Infiniti Q50s are BREAKING! 

U make me feel so much better about owning my Q50. I bought my 2014 3.7 5 months ago with 70k miles. I have done all fluid changes including transmission drain and fill , transmission still feels healthy. I also replaced the rear diff bushing and was able to find someone to do it for $250, so I got very lucky. You are very correct about the valve body situation, if it were to go out, I would probably upgrade to vr30 tranny bc I’m rlly tempted to go force induction. Other than that, my Q has given me no problems and runs great since my ownership. I currently have your catback set up with test pipes and a tune. It sounds so good and is very fun to drive. Overall, this car is an awesome platform, great job on making a video showing how reliable it is

I bought the Z1 rear diff brace after seeing your video a few months back and it was surreal. I didn’t expect to already feel it while driving out of the mechanic shop, 10/10, do you know why I now hear a creaking sound when from the rear -while accelerating from a stop? Happened right after installing the brace

Had my 2014 since new. The ONLY issue I have had is a rear wheel speed sensor. 118,xxx miles and car runs great!

Every car has its own flaws, these q50s have such a large following that those with issues tend to be more vocal about it compared to many other brands/models. Still, hard to find an equivalent platform that’s 8+ years old with any less issues. Everyone driving around in newer small displacement turbo cars are probably going to have a rude awakening of some sort down the line… probably not as straightforward as a diff bushing. 😅

My warranty covered my trans which blew not too long after I got it (70k) other than been about 30k that I ain’t seen a light and I drive my car hard, definitely would recommend fuel injector cleaner every once in a while to avoid losing any power and you should be good, just make sure you’ve got that warranty

I have 2005 xle camry and never had big issues with it just the regular maintenance over 350,000 on the V6 engine super quiet,and trans is still pushing along

Changed my subframe last week and did the differential fluid change and all bushing as well

Got my 2015 q50s at 45k now its around 85k..still running strong only thing I changed was the rotors to Z1 rotors but the squil like crazy now about to go back to stock then looking for a q60s come winter time.

144k hwy miles and am replacing it now,i still like my q so to me its worth it since its the only problem ive had,and have kept up with maintenance

my q literally breaks 2 times a month and i’ve spent so much on maintenance but hey i won’t have to touch that part again😎 love this car recommend 100% stop being scared of infinitis they just sassy

Had to replace my valve body in my 15 Q40 at 101k. Did it myself and with a friend for around $1600 after parts. So far so good. Running smoother than before.

70k 2015 my transmission defiantly felt clunky i had a code P0826. cleared code and feels better for now. local nissan/infinti shop told me 4500 out the door for a vr swap transmission. also other issues up untill this point stock struts at 29k blown . rear diff bushing and many end links. the car has been great other wise

I would love to see a video of your opinions on upgrading/swapping the 7speed trans. My ‘13 transmission is at 10200 miles and with wanting to do power upgrades the trans is my biggest concern.

I started having weird transmission issues in my 3.7 around 160k km. Sold it immediately and got a BMW 435i M-Performance. I love it.

There's a reason why Billy Bob's Garage will fix your Infiniti and you have to take your BMW to dealerships or specific shops. You'll always win on the Infiniti

Man last week my radiator blew and now this week my motor is shaking aggressively getting code p0304 for 4th cylinder misfire. Granted the car got 150k miles but i been doing regular maintenance will be fixing this weekend i hope

Gonna pick up a Q50 Hybrid AWD fully loaded, multimedia pack, 360 degree parking cam, sports brakes everything, cant wait. Only thing im kinda afraid of is the mileage as its in 150k km (about 93k miles) but it has a full service history for the first 50k miles, only serviced at Infiniti, after which it got to an old Porsche collectors wife, so I have high hopes that its a-okay. Thank you for all the vids on the platform, yours is the most in depth of all of content creators. Its a bit over the market price, at like 22k USD, but eh, you pay for a quality car. I hope I will be just as happy as you are with yours!

My friend recently had his rear diff bushing replaced at 49k miles (2014 RWD). He got the Z1 Motorsports rear diff bushing set for $200 (it was on sale for $50 off around the 4th of July holiday). Labor where we live cost him $700 to replace it.

Same 7AT from “Jatco” in the 370z? I had mine replaced at 56,000…. Been fine for the past 50,000… I think you do have to do the fluid change and understand that it’s a liability if you beat the snot out of it…. I plan on VR30 swap…. Much faster cleaner shifts

My valve body seems to act up under low throttle low rpm shifting between 1-2 has been that way for over 60k miles now vehicle has 200,000 miles on it currently, transmission fluid change did nothing to help but vehicle remains consistent knock on wood it has been One of the most reliable consistent enjoyable vehicle's and I've owned many reliable platforms owned including The gm 3.8, I didn't break a front u joint which shattered the front differential

I just went thru the valve body issue at 65k , was gonna replace it but went along taking the car to a shop to get a vr30 trans installed for less than 2k🔥 drives amazing now

You described me right now 😅 I'm thinking of buying a 2016 q50 400 for 26k with 65k miles but I'm afraid it will be a nightmare and specially the fact that it has some mods to it like the exhaust. I am afraid that the previous owner had fun with it and left the problems for me to deal with.

My 2015 hasn’t had any valve body issues yet or rear diff bushing issues yet either and I’m about to turn over 107,000 miles🤞it’s still a great whip tho!! like you say they are getting older and things do happen.. but you don’t hear nothing but the complaints, you don’t hear about the people who have mo issues but any car you buy will have some things that need to be replaced after some period of time!!! I think either way the platform is great and the car is just all around sound and a lot of fun to own and drive daily 💪🏼💯

Saw a q50s dropped off at the dealership by tow truck. (Lowered, exhaust, nice wheels, custom wrap) Overheard the owner say he had just purchased it 5 days ago, no start and even when jumped, still wouldn’t start. I went back to the dealership to pick up my title 1 month later, saw the same Q still parked in the same spot. 😬something terrible was definitely wrong with that Infiniti.

2014 Q base 3.7 Just hit 140k today no issues just regular oil change every 5k and i did rotors and breaks and sepertine belt only issues ever. I drive it not hard but I do have fun I love the car so far no complaints!!!

2014 Q50a (yes i know) Got it for 7k in 2019 clean title 55k miles. 115k miles now i banged on it from time to time since only thing i do is hit the freeway with it... have a misfire changed all sparks and ignition coils checked for leaks. Took it to a mom and pop shop dude said it was the head gasket. Was thinking of getting a used motor and going VR trans.......but i might just go ahead and rebuild the motor to go Supercharged make a light 500whp nothing crazy.

Just replaced the valve body and sensors in my 2015 Q with 86k miles. It was just shy of $3,250. Wasn’t driving the car hard, was in standard mode, went to the gas station to fill up no issues but when I left it wouldn’t go past 2nd gear, couldn’t change the car into any other mode. It’s now fixed and running perfect again!

35,000 km 2015 infiniti q50, own it since november 2022 and no problems at all.

i have a 2015 q50 had it for about 5 years bought with 38k miles never hard a issue with it till recently with the valve body. car jus hit 102k miles

Mine always has tiny air bubbles in the oil and the motor makes some pretty bad noises. It's quiet now but not sounding too good. It's a 2015 with 98k mi.

The people who complain about car issues are clueless and doesn’t know how to maintain cars in general. Car will break if not properly maintain as simple as changing oil 3-5k miles. I have a q50 3.0t bought used at 30k miles and now sitting at 93k miles has never have any issues except changing the serpentine belt cuz it was squeaky have new intake and z1 hoses as well. I changed it every 3k miles with Nissan oil z1 oil bolts. My car STILL DRIVE SO DAMN GOOD LIKE BRAND NEW. No turbo problems at all boost still kicks in. Those people who break their cars are clueless who can’t maintain simple maintenance. They abuse the car and can’t take care of it it’s simple as it is.

Bought mine june 26 & 3 weeks later valve body went out omw to work so just be very cautious other than that i love the car

I wonder if the rear cradle for the Q50S is the same for the Q70L. At some point soon I will have to replace it on my 2015 Q70L. is there a known issue on why the valve body will fail? My individual Infiniti Q70L just clocked over 200,000 miles. I have serviced the transmission every 50,000 miles. I’ve noticed that as I approach 50,000 miles the transmission starts to slip and buck at low acceleration particularly up a hill. Once the transmission service is performed, it starts to operate normally with no more bucking or slippage. In my honest opinion, it’s a lack of scheduled maintenance. Obviously, the engine oil should be replaced every 5000 miles with good synthetic oil. The transmission should be serviced every 50,000 miles. The differential should be serviced every 60,000 miles. The brake fluid should be monitored and changed when water is detected. The coolant should be serviced every 30,000 miles to 40,000 miles The transfer case should be serviced every 50,000 miles. All these Infiniti 3.7L VQ engines with the seven speed automatic simply require scheduled maintenance.

Yup I had transmission problems I just vr30 swap my transmission it's worth it

i juss bought my 15 q50 on 7/24 with 53k miles. it was an older couple that owned it and barely drived it

My friend got a 2015 Infiniti q40 basically a g37 different name from caravana with 50 k miles and right after the valve body went

I love my car 2015 350gt hybrid … however the valve body is stressing me out! Bought one and it wasn’t good ….car parked over a year😢

Had mine for 96k miles and dozens of street takeovers so it’s been sideways for a good portion of those miles. No spectators hit and no mechanical problems ever 😎 🤞🏽

Hey SCS I have a question. I have a G37 but same Valve body as a Q50 3.7 and I found a $1500 level 10 transmission I'm thinking of purchasing but I don't know if I should get that or just do a VR30 upgrade.

The valve body messed up on my at 120k miles. Took it to the dealership and they fixed it for free with warranty.

had a valve body issue on my old 2017 3.0t. Input speed sensor goes out and puts the car into limp mode.

2016 3.0TT here. Car stopped shifting this morning on the way to work with no warning signs beforehand. 55k miles. I baby the thing so I was baffled. $3,011 total. Here’s to hoping it was a one-time issue. Had to replace the rear differential gaskets earlier this year too.

Have u heard anything about 3.0 Transmissions? Did those have any issues ? My vq transmission went out wanna do a vr swap but don’t know if they even good. No one seems to rlly know

Hey SCS I’m thinking of selling my 2014 q and getting a 2019 3.0t from a private party and i wanted to ask you what should I check before I buy to make sure car is healthy? I just don’t want to get it then the turbos give out or something cuz i really have no clue how they maintained it and some people listen to infiniti and do their oil changes every 10k miles 🤦‍♂️

Somehow landed in one with the valve body issue after watching this😅

I have a 2015 3.7 with 154k miles on it and have changed Valve covers at about 100k. Currently have a vacuum leak that i can’t find but most likely an old hose.

Infiniti is a very good and reliable car 🚗. It's not the car it's the driver. If you drive it like a grandma it will last. If you dog 🐶 it like it's stolen it will not last. Just food for thought. I have some cars to go fast in when I feel like it from scat packs to 350zs. My daily driver is fast enough for me. 08 Acura TL type s

Keep Trans Fluid Changed and use a Trans Cooler, Great Video as always

I had the valve body issue at around 75k 2yrs ago. I bought a used one from a Q70S and had it installed all total for under 500. No problems since and I'm at 91k now. That's the only issue I've had with the car.

Put 194k KM on my 2015. I did not, baby the car, and did many full throttle pulls... a little Rev flair and slipped out of gear once in a while. Apart from that, just regular maintenance and very reliable. Replaced a throttle body and 2 front wheel bearings during its life. Miss my Q50

Don’t own a q50 but my auto 370z transmission broke a 2nd time on me. When you try to take it out park and put it in drive or reverse it just stall and cut off. Now gotta find yet again another transmission or pay extra to try to get the vr30 transmission to fit in my car. Worst transmission I ever dealt with🤦🏾‍♂️

How long does the q50 hybrid bat last

Had my fluid flushed every 40k miles. I'm currently at almost 90k miles on my 2012 mostly hard city driving... no issues...knock on wood .

My 2015 q50 , valve body went out at 72k , alternator went out at 75k , heater hose coolant leak , Door Lock actuator went out for my door, Oem Brake pads suck , Z1 undershroud 🙌 saves oil pans , this Nissan sucks I’m prolly gonna go B58, I fixed all this stuff, the car runs great

I have a 2017 Infiniti q50 3.0t first owner my engine is going out at 105,000 miles I fill eventually this cars will go up in value good vehicle but has many issues

Had to replace transmission twice due to valve body issues even though I own the g37

2014 q50 with 123k miles and my baby still running flawlessly 🙏🙏🙏 (I’ve been the only owner)

I have a q50 3.7….. trans went out at a 100k replaced it with a used one and now my down shift is a little rough. No codes is showing any suggestions !?

2015 ‘15 3.7 43k miles for $21,650 been itching at this buy for a bit now any advice?

had mine for almost 3 years im around 50k no issues yet lol

I’m having valve body issues what’s the best option for replacing that part

Then the ones with turbos, they are going bad. Dont make them like the G35 anymore

Is the vr30 transmission upgrade a performance upgrade or a maintenance fix?

Lookout do you even still have your Q50? I replaced my valve body at 100000 miles these things are like on a scheduled failure plan. Steer away from eBay purchase at stealership:(

How you put your top screen like that, rather stare at that then the gps 😂

The valve body problem isn’t exclusive to the Q50. When I was an Infiniti tech I also replaced them on the Ex and FX SUV’s. I’m thinking it’s just a faulty component on those particular 7AT’s on the 37. Not that bad of a job to do honestly. Just a bit messy lol.

Because of these issues, is that why they are so cheap aftermarket? I went to see a couple of Q50, but they needed thousands of dollars in repairs, and it had nothing to do with the things you mentioned 😅. I went to with a Lexus GS 350 with 186k miles that drives like a new car instead. $13k is what I paid for the Lexus. It's funny that one of the Q50 that I was going to go see had transmission issues 😮

How will I know if I'm having problems with my rear diff bushing?

Had a brake sensor issue, but its built into the master cylinder. $1 part. $3000 job.

What is a good upgrade for awd q50 to get better 0-60 times?

46k miles with Value body issues.

So I just bought a Q50s redsport, does it has a better tranny than the other platforms of Q50’s?? Should I be worried?

I have a 2018 q50 red sport 400 and it just stopped running at a stop light couldn't get it to start and when I went to the mechanic he showed me how hard it was to try and crank the crankshaft by hand I think my engine if done and he can't even figure out why. Engine has plenty of oil in it.

Is it worth it as a first car? I'm okay with learning how to fix things like the valve body, I've been looking at a '15 3.7 Premium AWD. All highway miles probably, judging its yearly mileage.

my 16 q50 3.0 breaks fucking constantly. I'm in the process of switching everything back to stock and selling. ill always love Infiniti and Nissan but I'm switching to German. looking at an Audi s4 or something with a b58, only because working on them is easier. my q50 has gone through 4 sets of injectors, oem injectors failed, then failed again so switched to aftermarket, which also eventually failed, then got warrantied with an upgraded set, which also failed. in process of getting them replaced and then selling it. somehow both throttle bodies had to be replaced, my block was porous so that was replaced as well, water pump had to be replaced, turbo seals went out, had them replaced under warranty, less than 10k miles later blown again. idk how others have such good luck with their 3.0t, but mine has been a curse, i know this video is about the 3.7 but still. Seems that the 18+ vr30s have been good though, so maybe just stay away from the 16-17 vr30s lol. Edit: I suppose its worth mentioning it was modified. it made 530whp and 480wtq and people are prob gunna say its because its modded but I haven't seen anyone at all with his many issues lol. But at the same time I've seen people with completely stock Qs having a ton of issues

Iv got a 2015 q50 it's at 230,k / 143,000 miles and I beat the fuck out of it, floor it everywhere hard on the breaks sqweeling through corners, only problem iv had is a fuel pump failure with cost me 1000cad out the door I love this car

I have zero issues With my 2014 infiniti Q50S hybrid and it has over 150,000 miles

I just had my Q hit and run totalled unless I got 20k to fix. What should I get next since I didn’t have insurance still owe 14k..

do the hybrids still have the value body issues?

i just got a 2014 q50 (3.7) the 3-4 shift slips, is that anything to worry about?

What’s the symptoms of the valve body issue

Don’t get a old Q50 that get miles on it and had more than 2 owner simple as that. Or make sure it’s clean.

The rack and pinion is also an issue for higher miles

Anyone that somehow thinks a BMW over a Nissan product in over all cost of ownership if you actually take care of the thing deserves what they get. We're taking about a cross brand shared platform with a "cheaper" brand vs a European congomorate if very particular parts and platforms.

2014 Q50 rwd 86k miles and valve body TCM shorted out. Got a refurbished valve body and TCM was bad on it too so I got stuck with a $550 labor bill. Now saving for a brand new Nissan valve body for $1700 and hopefully a warranty. Then I will change my transmission fluid every 30k so hopefully the TCM won't short again lol also thinking about installing a transmission fluid temp gauge. Oh and apparently my sunroof drain is clogged on the driver side lol

Since all the Qs are being sold as used definitely check up on the transmission make sure its good before everything is finalized on the deal! Story time: Carvana fucked me over and my car was shifting hard as shit, so luckily i caught it early and got it replaced with a new transmission under the 100 day warranty.

The valve body issue is my only problem with the Q50, besides that it's great.

How are the 2018+ 3.0t models?

Get a turbo transmission from a 3.0t slap it on your q and u should be good

I’m at 65k 3.7 I need to sell this thing asap

Level10 has a “Valve Body Fix” on their website for 700 bucks...is that a viable solution to the tranny problem assuming it hasn’t already failed?

My serpentine belt just popped 😂 was a $1300 infiniti fix but she drives new. My advice for 2016+ people Fix the damn belt before it snaps😂

How much does your (and anyone in the comments) car insurance cost for the q50?

Oh yeah 14 and 15's are having major issues. The misses 15 Q50 had $6000 worth of issues. Particularly the wack ass valve body's thats in them!!!

My 2014 q50s it at 147xxx, dropped 2 inches and awd.. no problems... hopefully i dont jinx myself lmao

Im dealing with a valve body problem🤦🏽‍♂️

I’m currently going through this I’m on my second valve body I’m getting a new transmission I had the car for 4 months

If you have the money just go get a lexus gs350 around the same year. Bullet proof cars

I feel like 80% q50’s are rebuilt definitely the 3.7 more then any car Ive seen

2019-2020 VR trans with flex plate. Solve that issue.
