I needed to re-launch this video again so Part 2 (law suit) will make sense when it airs at the end of the week. Sadly, This was literally a 2 year process that hung over my head and for anyone that realized, you are a true fan! thanks everyone and we will see you on Thursday for Part 2
Yep. The problem is even when you go above and behind for people it’s still usually not good enough and they’ll find something else to bitch about it in this case sue for…
I would have asked to see freeze frame data on all those codes looking at mileage (what occurred first or all at once), RPMs, and my personal favorites, throttle position and speed😉.... you may even be able to get fuel tank because if they were full throttle on no gas they could have leaned it out (fuel trims also tattle on a lean condition). That checks out, not his fault.
Right, because everyone drives around in their new vette with the throttle WFO, on an empty tank of fuel, long enough to make a lean condition capable of mushrooming a lifter...
@@bdd1469 well that is what happened to the engine right? Maybe he got excited and overreved the engine, now Cole when you go to shift and that little needle goes into the red and reads 9,000 rpm, that's bad.😉 my point was all kind of things could have caused it but the freeze drama data doesn't lie.
I was a die hard GM fan also I have had multiple Platinum ESV Escalades and GMC trucks. But had a 2019 Denali Ultimate XL with a folder two inches thick on problems. I also had a 2021 Sierra Denali Ultimate I got rid of after 8,000 miles. The quality just isn’t a priority for GM anymore.
I'm a GM Tech and specialize in Corvette, Camaros & CTSVs, its straight up a valve train weakness issue, "shit parts", gm ecms data log rpms, speed and everything else, we can see it. Problem is 90% of the time the vehicle was being driven normal when these failures happen, luckily for my dealership when this happens we permanently resolve the issue with having a somewhat local speed shop replace crappy part with aftermarket parts, and problem solved.....I'm not gonna advertise said shop but we are in Texas and we love speed.
Right, we had a problem with a truck that was always just putted around. Lifter actually separated in the middle. Came out in 2 pieces but didn't hurt anything.
Looks like I did it right to keep my beloved C6 convertible. These were absolutely reliable. Even here in Germany, problems with engine, torque-tube and the A8 transmission, are well known with the C7 . Looks like the C6 was the most reliable of all corvettes, lets see how the c8 will perform in this aspect.
I bought a used 15 silverado that came with a module that was plugged into the obd port that disables afm. Gm ruined a great engine with afm. The messed up part is that afm doesn’t even really increase gas mileage you get like 3 more miles to the gallon if that
I've been watching this channel for so long, i feel like i've seen an episode just like this before on your channel. With the corvettes, with the gm's v8 and engine valve shut problems etc.
He Craig, The displacement on demand (DOD) can not be removed by tune alone as the VLom, DOD lifters and springs are still in the engine. The issue with the lifters/springs collapsing can still occur even if DOD is not on/active. The lifters and springs must be changed to regular lifters along with the vlom removal to solve this issue. Note: all push rods should be taken out and checked also, a lot times the rods get bent when this issue occurs. I believe that low oil pressure in the DOD system is the mail culprit for the collapses.
Software shutoff with hardware in place takes care of most of the issues such as oil burning and stuck AFM lifters. A buddy of mine even had a collapsed lifter. He sent the PCM out and had the software turned off. Reinstalled it and drove it on the collapsed lifter. The lifter sprung back and its been running fine for close to 1/2 a year later with no issues. He was suppose to bring it to me (instead of driving it) for head removal and lifter replacement (or pop it back into place).
I’ve shut off 10 of them they are still rolling down the road way after the expected lifter failure shutting them off with software before 100000 will most likely save you a lot of money
Gm should be able to tell you if the engine was over reved, Like the guy posted below, If Not I would do all the work in house get good with those V8s be known as the V8 specialist You like them that's all it takes, No for real though it does Suck especially in this Stupid recessionary- inflated economy, It's real easy to F up with a manual if you end up in the Wrong gear down shifting if you don't take the time to get use to the way thie shifter works, That's why some hot cars had Gated shifter to help prevent this Nasty shituation.
Craig there is a RU-vid channel called Race proven motor sports and all they work on are corvettes and Camaros and every car they do they put in a new cam heads lifters because they all suffer this exact problem so they do the work before it happens!!! Check um out
yep, i have a few friends with tahoes with the afm and all of them have been back to gm for lifters and bents pushrods due the afm failures. The latest being a 2021 with less than 20000 kms and in the shop for a month for valve train/pushrod replacement.
Those Chevy LS v8 active fuel management engines are a NIGHTMARE. Stop buying those until they either recall or fix in new models…way too much work that is supposed to go for a flip
The dealer will not delete the dod system. It takes a lot more than a tune to get rid of the dod system, you can buy a kit and send the computer out to have it deleted but the mechanicals have to be done first. The dealer won’t do that, in some states it’s technically illegal.
Your correct!.. The good news if you have a C7 with a manual, it won't go into V4 from V8 unless your in ECO mode (In my experience).. I drive in tour mode most of the time, then sport mode on occasion.. no issues solid engine!
As much as I like Mustangs, I think it was a ‘99-‘04 GT 4.6. Not worth comparing to a Z51, unless you are comparing reliability. Why am I now remembering the fable of the Tortoise and the Hare?
I would do a DOD/AFM delete on it, get LS7 lifters and a Katech valley cover, might ss well do a performance cam and BTR valve springs. The motor would go for over 200k.
There is also a huge issue right now with replacement cams and lifters being made from junk metal "ask Mr Wizard" where you have to buy NOS lifters and cams for crazy ass prices.
Replacing a GM gas engine with less than 71K miles is shameful. Blame the manufacturer, not Craig. Thankfully electric cars are more reliable and now available.
Like other people said there's got to be a way to delete fuel management and track the car and see how it was performed you know he beat it he should have kept the mustang
Oh I love when dealers act like they gave money off. Clean Retail 30k avg 22k poor 10k Dealers prices it's 29.999 every time. It's got scratches and dents blah blah blah. Only like 3% of cars sit at very clean retail. You price it high so you get what you want. Stop acting like you give money off.
Everyone blaming the customer is ridiculous. If someone gave you $1000 and said “make the lifters fail and wipe out the cam” the only way to do it is let it idle for hours. Doubt the customer did that. Bad timing and flying wheels is a G for stepping up and solidifying his business reputation. Don’t give GM the credit. America is pimped out by the clowns in office which means you and me pay for it
You are way too kind!!! I am in Indiana. I would buy off of you if I ever needed a vehicle. As is is as is around here. You are one of a kind!! Your care!!! OmG!! Just heard there is part 2. WTF
Never trust the dealer. I would have my own trusted mechanic look at it. I have had a chevy V8 in a Silverado LT. Did not have any issues. I have a 2020 Jeep Wrangler. Had about 20k miles and dealer tried to tell me it needed breaks and pad all around. Most of those miles where hwy. miles. I have 34k miles on it and no issues with breaks to date. Can not trust dealer service dept. This at least the 4th time a dealer service tried to fix something that was not an issue. It sounds like you did the right thing. Your in business for the long term, not for short term gain.
Yeah that customer....if I had the opportunity I would baby the heck out it. The value seems to hold well if I am not mistaken. I'm int eh Carolinas and I cannot find ANY nice ones. At all!!!!
anyone tell you that you look like robin williams? lol... anyways.. I would make the buyer a deal saying he can't give a bad review to your shop. i'd give the guy his money back, take the car back.. buy a wrecked in the front corvette on maybe copart or something and put the wrecked car's engine in that corvette and sell it for breaking even. send the junk corvette to the scrapyard for $400. it probably would cost you more money, but one bad review will turn a lot of people away from your business.
Whats the reason you fired german? He to big? wanted to much money? Found out about how bad of a dealer you are? JW.. Also youre the problem why dealers are charging such high prices, OH just get it done, oh whatever the price just get it done, dude you're a horrible businessman, i guess you need people that can work on cars there huh..dont fire everyone then!
Just curious do you hit your head often, cause you keep buying gm’s crap and fixing it over and over. Love the channel, if you want to lose money up front buy my tundra for more than it’s worth and I’ll be happy….

I love the videos but man, you really seem to give some sort of deja vu moment during these videos by repeating yourself and in this video you repeated the story about selling a vette and the motor failing 3 full times... I understand the algorithms and such want you to make longer videos but man they are super hard to watch because of this.
1. service rear end light.... get this... is usually a dying battery. However, if there is actual damage to the rear end that means someone used launch control and didn't allow the brakes to release before launching... lots of rear ends blown catastrophically due to this at the track. 2. 6.2L engine has know damage issues in all Chevy cars due to long term V4 mode. in the 7 speed never use ECO mode. you don't save any gas anyway. I just drove my C7 to Nashville from Omaha and back. With ECO i got 31mpg. In touring i got 29.6 mpg. Never use ECO. Fortunately i bought my C7 with lifetime drivetrain warranty so I'll drive it forever.
Vehicles are a crap shoot especially in the past 10 years - with all the new computer stuff in them, new technology, etc. etc. Doesn't matter what make or model.
@@anthonylarocco6763 I’m somehow missing details: mileage, condition, etc. Was it a silver pre-‘05 4.6L ? If it was low miles and tight. Those can be a bit sloppy but it looked clean. How do you define “today’s market”? That car is known to run, these Vettes are not.
Buy yourself a hptuners device and disable AFM/DOD on every GM car you get. Device costs $300 and credits run $100-$200 per car. Easy to do. Takes 10-15 minuets.
Anyone reading the comments, the only way lifters really fail is because insufficient oil pressure at idle. Gm and Chrysler would rather have low oil pressure at idle than take a hit on EPA ratings. Let’s throw away cars less than 10 years old because personal vehicles obviously pollute more than diesel semi’s and garbage trucks driving every single day all day
All GM engines that have the cylinder displacement on demand system are prone to failure at any time, no fault of yours or the new owner, it's a garbage system with a high failure rate. FYI, disabling the system does not prevent the failure of the lifters, it just helps the drivability issues that the system creates, (fluttering and surging etc.)
I’ll say this it kind of sounds like you bent over backwards to help someone you were not obligated to help. You did that as a good businessman and I’m guessing to be a decent human being. Then in exchange for you being nice he turned into a dick the and tried to sue you. Unfortunately the guy should understand when you buy a used high performance car there is a good chance something will go wrong because the previous owner treated it like a high performance automobile and beat on it a little bit more than they would have a grocery getter
That may be true, I had my 2015 Camaro SS lifters do the exact same thing and mess up the camshaft as well thankfully it was under warranty and they fixed. But I never raced it to
If he did the dealerships tech would've caught it, GM Ecms data log every inch of your driving and whatever dtc pops up we can look at what speeds, rpm, air, etc triggered that code...
A couple years ago, I sold my 2014 Roush Mustang (550hp) to a private out of state buyer. As he left my neighborhood, I heard him leave rubber in the first 3 gears. About a month later, he called to tell me the clutch was shot, and he'd like me to split the expenses with him. (I drove the car for 5 years with no issues whatsoever.) I asked him how he drove the car, and he told me he babied it and drove it like a grandma. Case in point: Nobody buys Vettes, Camaros, Chargers, Mustangs, Vipers etc to drive them like a grandma. Needless to say, I did not contribute to the new clutch. Live and learn Craig. You're a good man, but these high mileage, high performance vehicles carry a bigger risk than the Accords and Camrys of the world. I admire the fact that you stood behind your sale, but within reason. Beard looks good too!
I mean unless he has a scanner in his POV there’s nothing that says you didn’t clear the engine before giving it to him. Not saying you would. I’m giving his possible perspective since you’re saying that in only 150 miles he managed to destroy his engine lol. But sure you could look at it that you lost 4.5k but you could’ve lost the full amount if you would’ve driven the rest of the mileage just be grateful for the partial loss and move on 👍🏻 you handled it the best way possible.
It's a very high failure rate problem with the GM V8's that have the AFM system, could have happened at any time, not at all related to being abused, just luck of the draw when it did it.
This video is Deja Vu. Is this a re-upload? Anyway, magic words "Corvette" + "76,000 miles" + "used car". Not saying a Corvette won't go the distance, but it takes TLC. I have owned 3. I sold my 2002 for basically scrap metal on Craigslist at 60k miles, my 2004 sold for what I paid for it at 40k miles. My 2007 now only has 23k miles, and I can't get any help with the seats from the entire supply chain, including the dealer.. They want $1300 parts-only for one headlight. Point? Do NOT hyper mile a Corvette unless you have a garage. Weather beats the crap out of these. And yes, the Active Cylinder thing is a disaster you have avoid. Thanks.
And, as I said last time this video was here, partner with a warrantee company, include a service agreement in the sale, and all these shenanigans go away?
i used to work for an aftermarket automotive parts store. what you said about the active fuel management system being junk & causing problems makes a lot of sense. had several several people wanting a code read for those GM V8s. the most bizarre one was a guy with a new (for the time) low mile Camaro. i don't remember the specific code, but it was a P code that ended with a letter d after the number. couldn't find any information for the specific code. fortunately for him, he had bought the car new from a dealership. so the car was under warranty. a week later he called the store to tell me that the dealership couldn't figure out what was specifically wrong with the Camaro, and that he was now the owner of a different vehicle ✌️🐝➕
I would've made the seller less unhappy, and the buyer very happy by sending it to a reputable speed shop, have them put a tsp cam and lifter pack in, tune it and wind up with an absolute animal of a vette for far less than dealer work would be for just replacement gm parts that are still made of weak materials. I'd split the cost with him and call it a day
It’s not your problem once he drives it off the lot. It’s a used car with 70k miles. His problem not yours. No way I’d pay for it. If he wants to not worry about fixing it he should have bought new.
He said the customer was a recurring one so he probably wanted to keep him happy or at least help in some way. It’s more profitable in the long run if he spends a few bucks to help the guy now and the guy later comes back to buy more cars
It's tough because if you offer for anything now becomes your liability, At least that's what it is here in Washington, We also can get hit with an expected use law. A used car It's purchased too run and drive and should run and drive. I would ask the dealer if there is a data logging in the car See what the Max RPM is and when it happened, if all is good I would offer to split the $6200, From there I would step back and not have anything to do with the repairs. thus relieving the dealership of liability.
36k was a steal on that car even 2 years ago when I first watched this video. The the coil/plug service is kinda what bites you, cause the lifter issue was undiagnosed at that point and it was cylinder 8 for both issues right? I would either halfsies the engine replacement and take the OG block for a project or just buy back the whole car for what he paid, rebuild it and probably sell it for more than 36 while monetizing the entire rebuild on youtube.
All the modern Chevy v8 engines with active fuel management engines need to be deleted. Buy the cam, lifters, etc. send the computer out to have the fuel management deleted and your good. To the customer it costs about $5600 to you it’s about $3500 paying for your labor. Worth it! Active fuel management engines get about 22 mpg…… deleted engines get about 23mpg
Programming the AFM OFF only is a very temporary fix, those engines REQUIRE full dod/afm delete, to properly do it so it doesnt ruin/prematurely wear engine parts down
I think you need to find yourself a GREAT independent mechanic who knows how to work on all these cars or at least GM or one brand car you have a lot of. TO CUT YOUR COSTS
Your being sued because no good deed goes unpunished. Did you as in past videos have him sign a new release over the repairs? I remember you had the person do that in the past.
What should of been done is sell it with a warranty through a third-party and it's problem solved. It's a Z 51 Corvette we all know what the guy did to the car he didn't drive it not to get on it.
Hey Craig I have a 18 suburban and had a fuel injector misfire in number 6 Chevy said to just replace and reading forums your more than likely going to have a check engine light due to the new injector sending more fuel then others So i found a oem set of 8 for 280 bucks on Amazon and 300 bucks to install at a local mechanic and 30k miles later no problem brother On these Chevy engines and fuel injectors you gotta replace all of them
Yeah I learned the hardel way, you have to get genuine GM parts. I kept putting knock sensors in my avalanche from eBay and CEL always came back on. Went to AutoZone spent $200 for two knock sensors. Cel never came back
Disabling the AFM system isn't really much of a "secret;" it's been common knowledge for years now -- just google it. The one detail left out was how much Craig had invested in the Corvette. I mean, if he bought it for 10 grand to begin with, my sympathy is somewhat DAMPENED, if you know what I mean.
