Hyundai Santa Fe - AWD Failure - What you need to know 

Just discovered this exact problem with our 2015 Hyundai (108,000Kms; Melbourne, Australia) - 7months out of warranty!! Doh! No idea until the service centre diagnoses it and quotes $3000 for parts. Thanks for the video - nicely put together and clear! Car has been really great until now. Best of luck! Very kindly.

So informative thank you. I've got this problem after 10 years of completely trouble free motoring. I have kept my tyres in good condition until this current lockdown and I am a nurse so I have continued to work through the lockdown without being able to access either a service or new tyres. My rear tyres have mismatched wear now. West Auckland Hyundai have been good. Thanks for this video. Makes much more sense now.

Thank you for the video; it was helpful; pretty much what I expected. I went to use the AWD and there we were without it, but, my vehicle has 350000km on it, I didn't pay much for it three years ago so it owes me nothing. Probably the coupler was going when I got the car, tire size was well matched and it has done no heavy towing as far as I can determine but it has failed. In view of the cost of a repair, the vehicle isn't worth spending a lot on and I was lucky to find another, again at a very good price and we have checked the drive, and it's tight as a new one. I'll part with the old one as a 2WD. A lesson well learned. Thanks for the information, greetings from Nova Scotia, Canada.

I found out the hard way this past Sunday (2/7/2021) I’m in the Southeast US. 73,000 miles. 2015 Hyundai Santa Fe Sport 2.0 turbo. Hyundai is going to fix it thankfully. It was the front differential like you described.

In the previous versions of these vehicles, the CM range, the transfer case was prone to fail if the owner hadn't ensured to make sure the tyres should all be the same size with equal wear as you mentioned. The service book also mentions this. Plus if you need to replace one tyre, and the other 3 are quite worn, you need to replace all 4 otherwise the system will engage the rear wheels on the road and just as in all part time 4wd systems something will eventually brake because the tyres won't slip to relieve the stress on the drive train take care of the tyre wear and the required tyre rotation and you shouldn't have any problems

87000 miles on my 2013, so far no issues with the awd. I drive in snow every year, use good tires and have been very happy with the performance. This gives me pause, however, seems like it might be a weak spot in the system.

Thanks Badger! Will keep this in mind to check when buying our second hand SF

Thank you for your video! I had the exactly issue with my Hyundai Santa Fe 2014 when it got 170000 km, no snow or hills only highways. The rest of transmission parts were ok like new ones. As you well said, the point here is to keep the tires and alignment in good conditions. After I exchanged the satellite box part the car is awesome again, with the 4 wheels working in the same time. No other mecanic issue with this wonderful vehicle.

I've got a 2008 Santa Fe, same 4wd system. Last winter the 4wd worked wonders, during the summer months I've had a control arm fail and wear out the front tires just enough that it's noticeable on the inner part of the tread. This winter I've "suddenly" got no 4wd, no warning lights, no sounds to indicate failure, it just doesn't work. Prop shaft does not turn when the car is lifted, but the rear wheels turn when the prop shaft is turned by hand... Seems to be the same issue you had. Thanks for the nice video explaining this surprisingly common fault :)

Had this happen to our 2015 model with 90,000km on the clock last year. Suspect it happened after towing up a steep bank on loose gravel (took a couple of attempts to get up) also had 4x4 lock switched on. Car was six months out of warranty. However, Santa Fe dealership put in a goodwill application on our behalf and all was covered. Cars been like new ever since. Thanks for the great video detailing the problem.

Yikes! That's an expensive repair Jonathan! Glad it was covered for you! 👍

saw your post about a year ago when trying to figure out what the hard clunk was when driving in reverse. bought the car used from a private owner with 95 k miles on it and it was like brand new and had it checked out and all was fine. was driving in the rain when pulling uphill when i noticed no traction and just the front wheel slipping. Put it up and exactly what you said no drive shaft spinning. was debating fixing it with a used unit for $700 us plus $900 labor and fluid but, the car has the 2.4 theta engine which burns oil so idecided to just drive it in 2wd as its not worth repairing.too bad the privious owner wasnt up front because this could have been repaired under the original owner warranty for free. only bought it as i couldnt find any cars available when my like new honda crv was rear ended and totaled by the insurance company last summer. buyer beware and thanks for the posts. will be purchasing only hondas and toyotas as they are pretty much trouble free .

Bought a 2015 Kia Sorento in December 2019. With just over a month left on the warranty, transfer case went. I had a feeling something was up. Had the dreaded clunk sound (feels like I actually hit a brick wall when it happens) when reversing, not every time though for some time before it went belly up. Also at times when taking a corner from a standing start, I'd get the dreaded rumble feeling and sound from the rear of the car. Long story short: I dodged a bullet. The repairs were roughly half of what I had paid for the car to begin with. Luckily covered under warranty, a month before it was out of warranty. Transfer case, coupling and rear diff replaced. Rebuilt gearbox (or so I understood), as well as new side shaft (again what I understood). The dealer that did the job was fantastic. The master tech that did the actual work, was absolutely excellent. Likely to sell it now though, as this scared the crap out of me. Looking for a Paj or Paj sport now.

Thanks a lot for this message, I got the same exact problem and the car is fairly new

I just bought a 2012 Santa Fe GLS AWD with 3.5L V6 and only 17,800 miles. I'll keep my fingers crossed.

That is a huge flaw. I'm glad that it was under warranty for you.

2007 Santa Fe with AWD indicator flashing and ESC off since January 2022. No error codes on scanner have not taken to dealership for inspection.

If I had a Santa Fe I'd watch this twice. :)

I purchased my 2013 Highlander as 2nd owner, 5 mths later front diff transfer case gone with $7000 for repair , it had had every scheduled service always at Hyundai 106000 kms, this is a severe manufactures defect! Hyundai have offered to pay half for the parts only $3000, I am now taking the dealership I brought it from (not Hyundai)to VCAT for the rest of the repair!

Excellent vid n educational. Hyundai SF has this problem all over

I have a 2013 SF Sport (Canada) that just rolled over 200000KM and had it in the dealer service as I had an engine light go from being on to flash. Dealer service said it was related to the engine recall issue and replaced it under warranty--my shop quoted me an estimate of $5K for a rebuilt engine, so I was glad not be out of pocket money. Whilst in, I was informed I need a new transmission I had to ask what the symptom was and was told AWD is not working on only 2WD--which sounds like the problem you identified in the video. I don't know how long this was the case but the quote for replacing a transmission given the age of the car is disappointing ($4.5K). I'm getting rid of it for a new SUV that is not Hyundai/Kia.

I’ve got a 2013 model which has just lost AWD, no warning 120k on the clock. It’s Out of warranty now too, eek!! We’ve already had the transfer case replaced in 2019 after a failure and now this. It’s my wife’s daily driver, never been off-road. Had the aircon fail 3 times, electric park brake fail once. Eats tyres and we’ve always made sure they’ve been rotated by a 3rd party company because our dealer service said they don’t rotate the tyres during a service. Absolute lemon of a car but when it works it’s a real nice drive

Common problem. Front Tranafer in 2014 blew at 45km under warranty. 110km the 4wd Coupler blew and warranty was denied. I have driven the car for another 50,000kms as a feont wheel drive. I have taken Hyundai to VCAT and they have capitulated 2 weeks befpre the hearing and will now replace the coupler under Warranty. If you get denied take them to Court. They know this is a problem and will try to avoid it. Call them out. It is a Disgrace.

Thanks for Video, yes I currently have this issue and suspect it is the transfer case unfortunately I don't have $4K plus for a repair, and this morning the nut dropped off the shaft on the Turbo and then shattered the impeller $1K for a second hand turbo plus labour etc... Our Santa Fe is a 2013 has now done 247,000 kms

Thanks man,that's my problem now!

I have a 2015 Hydundai x35 (has done 160K) and during a service they discovered I the AWD wasn't working (Front Dif Drive Splines stripped. I couldn't tell any difference when driving it, I've had it since 2015. My question is could I just get the oil drained and replaced (to remove any metal bits) and just drive it as a 2 WD? I don't really want to spend $3K on what is probably a $10K car now.

Great video Badger! Could it be people engaging the centre locker whilst having wheel slip, or does the car not let you do this?

I know this is 4 years late… but yeah I’m having some issues with my 2014 Santa Fe Sport AWD. I’ve started to notice that my tires will sometimes lose traction while going around some corners and accelerating, which has never happened before. When I have the car on the lift, start it and put it in drive, a bunch of traction control and ABS lights come on. When I press the AWD lock button, only the front driver’s side wheel AND the driveshaft spins. I’m concerned with this, because I wonder if there is an issue with the real driveshaft/differential coupler AND possibly the transaxle. The car only has 75,000 miles 😅

Just had 2016 Santa Fe Turbo Sport coupler replaced. 81,000+ miles on it, always had matching tires. Baffled on why this happened.

I've got my old beater version of this car with this self same issue. I'm half tempted to weld this joint together.

Thanks for your advice 😎

We have 2012 santa Fe, only used for school runs, never been off road, regularly serviced, last year we had to replace the engine, earlier this year we had to replace the gearbox, now we have a clunk from the transfer case and mechanic says it will fail any day now. Should have got rid of it after engine but mechanic said that was the big one you'll get years out of it now, then I argued to get rid of it after the gearbox, "but we'll end up with someone else's problems" Overall lemon of a car, I'll never touch Hyundai again

Excellent video only a Kiwi could give a subjective explanation. A lot of Auckland cars end up in Turners Christchurch

that's crazy that those splines stripped out, good thing for warranty

My brother has had two Santa Fe, he had exactly the same problem with both of them. He lives at the top of a big hill, and as soon as it snowed the problem soon showed up. He also had problems with the dual mass flywheel in both of them too, both falling to pieces at around 30 to 40k. He now has the equivalent Mitsubishi, and he went auto too. It's now done almost 100k with NO issues at all.

In my Santa fe 2007 4wd wont work, push the 4wd, it is show on the panel like is on but no traction on 4 wheels just the 2 in front, look like this is electronic can you show how to fix it ?

Thank you for the overview! Have just been told by Hyundai my transfer case has failed and the spline on the drive shaft possibly stripped. I have not seen any photos yet and we have had no sign of leakage. Always serviced with Hyundai Melville (AU) since new. They mixed up their service schedule this year and missed the 96month service. Looking in the records no sign of transfer case fluid checks or replacement to date. Milage is 107k in km. Car always driven light, never off-road nor towing anything. Hugely disappointing but hope Hyundai Australia will come to the table given low milage, loyalty and service bungle. Any suggestions most welcome.

2017 Grand Santa Fe (German), 200HP Diesel. AWD was still working, but driving fast on twisty roads (right corners), the car was shaking. Diagnose from Hyundai-Dealer, defective Differential. Whole drivetrain was replaced (warranty / 58000km). No Trailer or heavy loads. 4 matching Wintertires, Not old and equal on Profil depth

I have a 2014 been a great car to I got this problem. I noticed the problem at 90k could have happened earlier on. I have 22” tyres on mine and they said that could caused the problem. My warranty ran out so I been quoted 6k for the job.

Great video and very helpful. We've got a 2012 Santa Fe 224k has been very reliable until now. We use it to shuttle kids up and down the ski hill roads in NZ and handled it with ease over the last 5 years or so. Last week The car lost traction on a section of road that it would normally be a problem and the 4wd light started flashing. looks like we might be up for a new diff? CVs are up for replacement too.

I have a 2011/12 kia sportage 210000km. Same problem kia estimated cost to fix $21,000.

my 2011 has this now. was hoping to get used bits of a damaged vehicle to replace it as it needs a clutch slave cylinder as well.

Also this exact problem with 2015 Santa Fe Highlander 107,000 Kms Sunshine Coast. Over 3 years out of warranty. No towing ever but recently had the 2nd of 2 punctures a year apart on the Bruce Highway and needed to drive one Km on a flat tyre on both occasions to exit the freeway. Could this have caused the splines on the transfer shaft to shear off? Been quoted $6.5K to repair. Would I be better to just leave the rear wheels disconnected and operate the vehicle as a front wheel drive only from now on?

I own a 2014 santa fe and its been nothing but trouble for the past 4 years. I don’t understand how car websites keep mentioning it as a reliable vehicle. I agree its good value for options they provide, but reliability is garbage.

I had the exact same problem. Mine presented a large noise under reversing. Presumably the splines slipping. It was £2500 all in and unfortunately not under warranty. However the vehicle had done 80k miles. Very good video explaining the fault

Any way to weld that together? ive seen on trucks people weld rear diff Gears together with success.

It looks like the steel on these parts is not hard enough ! I also don't get it why they make such small steel teeth on such large parts.

I was willing to buy a 2015 one with a diesel manual but now I think I might pass

Had a transmission front seal leak on my 2012 - got it repaired. Took the Santa for a test drive of 4X4 and noticed no power to back wheels. Given that the prop shaft does not spin when diff is locked - I suspect its the same issue as you had here. Also, given that the transmission has JUST been put back together, I'm loathed to have them dismantle it again, and was wondering if it isn't a better idea to leave this alone until my next transmission service in four years' time (it'll give me time to save up for parts and labour). Do you know if I am subjecting my car to further damage by not addressing this immediately? The fact that you said you've been driving around with this issue unaware for some time suggests that this issue wont cause further damage to the car. Thanks for your great vids - I've learnt so much from them!

2015 model, mine had same problem back in mid 2020 and had it replaced as you did with a “good will” contribution from dealer. Now the AWD “Lock” suddenly engaged and no light indicator on the dash. Can’t get it to disengage so had to get it towed to North Harbour Hyundai. Awaiting their diagnosis now :(

I have just suffered this issue on my 2016 Santa which has only done 38,000 miles. Hyundai customer services are not interested in providing a post warranty contribution.The 5 year warranty finished the middle of last year (2021). Hyundai dealership are quoting £4.5 k for refurbished parts and over £9k for new parts. I have always used the same brand of tyre (Hankook) which came with the car. I have had the car from brand new and it has only ever been on the road and not off road. It seems to me that the parts/engineering are not fit for purpose.

I have a 2014 SF only done 89,000km had since almost new. Exact same issue with mid TF case and also parts in Trans. Quoted by my mechanic $7,000! It has just been shipped of the a Hyundai Dealer in Auckland for them to inspect. Spoke to Hyundai NZ, first question was about the tyres. This is a dodge the issue excuse from them. If decent quality the tyres would not cause this. Anyway tyres are new and to factory spec and rotated. So sorry Mr Hyundai. Will advise updates. But to me regardless of age it is only 6 years old with low K’s, it should not fail. My old 1996 Toyota Surf had done 300,000k’s and had a hard life, no engine or running gear issues.

Mine actually cracked the differential carrier in three places that you have in your clip.One part dislodged when examining it.I have approached my local NZ agent.Possibly some assistance $$ from Hyundai . Carrier splines not worn but transfer case spline was.

Stay clear of 2017 santa fe sport and various other models as well. EGR recall due to excessive rod bearing ware. Instead of replacing the engines Hyundai designed a more sensitive EGR and a software update. One year later rod bearing failure and only 28,000 miles on the it. Goes in next week for new engine, getting rid of it as soon as I get it back!

My 2013 Santa Fe has just been diagnosed with this problem but it still drives the rear wheels at this stage. There is a loud clang/clunk as I reverse up my steep driveway. It has done 180K and its previous owner was a rural person who had probably done a lot of towing and I do my share of towing too. Dealer has quote $6500 to repair. It should be better than this; there must be some sort of misalignment to cause this level of wear!

I have a 2010 Kia Sorento with 205,000km on it. We had the same thing happen to us. The only indication something was wrong was when the car was in reverse occasionally it would make a loud clunk. Went to tow the caravan up over a kerb one day and it started skidding. Its in the shop right now getting the transmission reconditioned and the transfer case replaced. The agent said 9-10k to fix, however I am getting it for roughly 5k from my mechanic. I will be switching cars as soon as I can to get something better for towing. It's a shame really as they drive so nicely and towing is a breeze.

2013 13500k mine did the same thing. Haven’t had it fixed yet. 2wd is good for now. Full service history.

We bought a 2013 Santa Fe new. Always serviced at Hyundai. Had the same problem at 50,000km in 2017. Checked under the car after a service, and found the prop shaft could be turned by hand. Repaired under warranty. Strangely I had never used 4WD. Never knew it wasn't working until I checked and hand turned the prop shaft. It must have destroyed the splines by just turning the prop shaft itself!!

Most AWD units dont engage all the time just when needed. Seems you wouldn't use the AWD much. Looks like a lot of soft metal on the splines.

2013 hyundai santa fe. Owned since new, only dealership serviced, never towed anything, never been off road. 110 000km same failure. Total heart break.

Thanks for that Badger, very helpful. I bought from a dealer, a 2010 IX35 2.0 L CRDI just over 6 months ago, as a tow car for our caravan. Currently under 190 K km. The towing capacity is 1600 kg and the van weighs 1450, so that should be OK. I didn't know about testing the AWD on a hoist and so the 1st chance I've had to experience the AWD was this week, towing the van up a steep gravel driveway. The AWD did not kick in, but the 4WD lock worked after a 2-3 seconds of skidding at a bit above idle speed. 1 does this seem to be the same problem, just that it has not deteriorated fully yet? 2. should it be covered under the CGA as the 3 month dealer warranty period has passed? 3. other online forums talk about the viscous coupler, is that the same thing? Thanks

Thank you for the explanation! Could you provide the part numbers for the precise parts you had replaced? We have an automatic 2015 Santa Fe with the same diagnosis. I’m having problems tracking down the parts however. Thanks again for your expertise.

Hi great video thank you. How can I lock my 2014 Hyundai Santa Fe into AWD and how do I release it back to two wheel drive. I assumed it did that automatically. Regards Geoff from Oz

2014 Santa Fe Sport. Only the front passenger wheel is engaging. Neither the front driver or both rear wheels engage.

Tks. Well Done. our 2009 Santa Fe, AWD coupling failed of course, right after warrantee expired. Now we are at 148K with good tires never towed anything and we have the thumping again, sounds like we are getting hit in the back. Thoughts? Thanks again

How do you not hear it

2013 Santa Fe Sport, 2.8l just got diagnosed with the same problem, not impressed with this news

OK, so the actual faulty area is the shaft that connects the transfer case to the actual gearbox output..... mine has gone and I was going to order a new transfer case, but not after seeing this..

I won't get this fixed by warranty 😢 220.000 km driven. 2013 Santa Fe premium. 3 years ago I had the back diff blow out on me. I got it then fixed because it was just right under warranty. Last winter I got this problem and I thought it was because I had bad tires. And having the same problem this winter but i checked the tires better this time. Even had them Special washed and stuff. And still had the problem. So I had to start google some more as a 4 wheel drive should not have had problems where I was having problems.

Hello. Great video. I have a 2013 Hyundai Santa Fe sport 2.0t and today in the snow my awd warning light was coming in intermittently when slipping and fighting for grip. I can’t find much info on it. Was wondering if you would have any opinion on it. Thanks cheers

Great video. I have a 2017 santa fe diesel 2,2 (115,000ks) , Took it in for a service and they came back with a report saying the diff coupling needed replacing as leaking oil. Does the coupling actually contain oil, if so and leaking cant the leak be sorted and oil refilled. If its not leaking from the coupling could it be the diff. They produced a lovely photo and yes there is evidence of oil leaking . shame I cant upload it. Its an expensive exercise so any comments or feedback appreciated. Thanks

I have a IX35 2015 off road wheels driving on sand I push Diff Lock and only my Front wheel worked

Hello i have santa fe 2009. Do you know is it a limited slip diferential or no? Im confused about oil replacment. LS oil or regular gear oil ?

Do you know if a 2010 Santa Fe 2.2 diesel manual can be driven with the propshaft removed, the central 4 wheel drive shaft?

That name has bad rep around here...My mate's just crapped the EGR cooler...They call theirs a C#nta Fe...Same heap with the DPF and all the other stuff.

Please state the part numbers of the parts needed to be replaced. It would be greatly appreciated.

You can end up with a lemon on the 2016 Tucson as well. They could never fix the dual clutch transmission and finally bought my car back at the original cost, taxes and insurance.

My Hyundai Tucson 2011 has a different problem, while on hoist the one side rear and front driver side spin but non of passenger side spin. What’s your opinion?

2013 Santa Fe Sport, 109K miles, KaPow, $5K repair bill. All tires worn same, but front and back different brands. Never used AWD, wasn't even interested in it. Now KaPow! Do I fix it or buy a new car? More will be revealed.

i initially thought not too much of the video warning as a small number of most brands have horror stories...which is rare and bad luck but after reading the comments i might steer clear of the Sante Fe....it reviews very well and I imagine its a great car otherwise.

I have a 2014 Hyundai Santa Fe, 59,000km. Description of issue: Road tested and confirmed noise. Took sample of rear diff oil and found to be very contaminated with metal fragments. Also removed the RHF drive shaft and found corrosion inside the transfer case and shaft. Excessive movement in differential to transfer case. Is this the same issue? We have been to the OFT / looked at Consumer Guarantees.

I use Santa Fe DM 2013. now it passed 180 t.km. Problems with awd were fixed at 100 t.km. In Russia nobody cares about your whehicle after your official garanty is over. So we paid somethinf about 1500-2000 dollars usa. At 125 t.km i had an issue with a/t transmission. Price to fix was about 2000 $ again. I had problems with 3/4 gear pack. All the frictions were to be changed... but befor that - i drived about 5000 km with 2 motobikes in trailer.. maybe it was because of that)

Have had this problem occur in the past week on my 2013 Santa Fe Elite Diesel. Done 122,000kms and a loud bang happened when taking off from a stop. Repair quote from Kaspa Transmissions is $7000. Ouch!!

Hi.. I'm concerned as I had to tow my 2010 hyundai sante fe. I forgot to tell the Tow Operator it was all wheel drive. He towed it about a half a mile to a mile, before asking...??? I feel HE should have known, as an Operator....‽‽‽ Seems ok right now. Should I be worried??? And what would I need to look out for to know if it had, indeed, been ruined. Been driving it for a few months, now, after tow. Not really noticing anything abnormal at this time...

What are those 2 bits called as I need to order them for my 2014 Santa Fe please thanks

I own a hyundai santa fe 2010 AWD and had an issue with turning my wheel all the way to the left when the caar wouldn't move forward and stayed stuck. Then I pressed the gas and it made a loud jerk noise that lashed the car forward. I took it to a hyundai dealership in Milwaukee, WI and they reported rear diff leak in cuppler and housing unit. Everything else works well but whenever I turn the wheel is when the car doesn't accelerate forward anymore. I tried my warranty but unfortunately doesn't cover it. What is the best fix and option at this point?

Hi, we have a 2012 Santa Fe 3.5L Elite that needs a gearbox repair after we noticed reverse was not responsive as usual and jerky and then a series of quick jolts or misses driving the motorway. 105kms, tyres are different make after we got two new tyres that were different to the existing two to pass a WOF (Typer Power tech said this was ok). Also tyre size (mags) bigger than originals (as we bought like this). Could this have been the likely cause of issues we are now facing? Hyundai service centre has changed the inhibitor Switch and Transmission fluid has been changed to see if that would fix the issue but it hasn't. Thanks

do you know where the breathers are on the transmition and diff are?

hello i have a santa fe 2001 4WD V6 right hand drive, i got a problem with it. the gear are not shifting. and on the dashboard when i put the gear to drive or (D) it shows (D and gear 3) at the same time. Do you have any help?

Hello I have exactly like this problem but my car is Tucson not santa, when I press the diff lock button it shows in car engine screen that is turned on but there is no action form the car just the front tires rotates and the rear tires does not move, what can I do?

It looks like a heat treat quality control problem. I bet the replacement parts are better.

Have a 2014 santa fe, 128,000km made a clunk when reversing, took into north harbour Hyundai & front diff is buggered, looking at $3,400 + gst to repair no warranty. Have recently been towing an English caravan but well within limits.

I'm sure it's been asked before but please can anyone tell me what type of oil is used to refill/ change the old one in the 4wd actuator?

I have a question I have a 2010 Hyundai santa fe limited edition awd 3.5l v6 and the viscose coupler is f**ked on it what happened if u still drive it

4/8/21 My 4 wheel drive has failed . 210000 . Hav owned it for15 months.Im gutted

Today it happened to me. 2015 Santa Fe 2.2 diesel 78000 km Drive shaft not turning when front wheels are. Drive shaft can be turned by hand when the car is stationary on the ground. I will disassemble it to make sure, but it looks exacly like the problem you had. Did anyone found a better replacement for the OEM diff carrier? Aliexpress?

Does this issue cause gear oil leake?

Good to hear from ya. Thanks for the info, think I will stick with a Jeep if I go 4 wheeling. Happy Motoring and off roading.

I have one those 2013 Santa fe sport with the same problem and I have a cuestión. this is inside that transmition or transfer case?

I have just had this happen on my MY14 plated Santa Fe, bought new (ex demo), at 120000ks, Always replaced all 4 tyres at once with good quality tyres, don't take it off road, never been under heavy towing, mostly school pick ups and long highway drives. Still under the after market extended warranty but dealer has told me they will only cover up to $1000 per warranty claim, there estimate is $4220. I will be fighting them.
