This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
The transfer case has locked up several times causing me to wreck once. The engine misfires and does not give the MPG advertised. The life of my family has been put at risk with little to no care from the dealer after several attempts for service.
My safety system service warning comes on for about 30 seconds and then goes back off. This has happened about 4 times now. The transmission causes my truck to shake randomly. My pulley is going out and the local dealer said they wouldn't replace is under warranty(even though my warranty was still is effect) because they said it looked like someone sprayed tire cleaner under the hood(I bought it from the same dealership that I took it to for this service.) The brake seem to shake already when coming to a stop. They seem as if they are wearing prematurely.
While vehicle is in 4-wheel drive or 4 auto or 4 L. It makes a grinding whining noise! I have contacted the dealer Newberry motors of Newberry MI 49868. I asked them about a service bulletin I saw on the noises I am hearing, and I was told service bulletins are only assigned to a vin number and not groups of vehicles. which is a lie!!! SO THE GRINDING NOISE IS BAD WHEN IN 4 WHEEL DRIVE. PERIOD. DOES NOT MAKE THE NOISE WHILE IN 2 WHEEL DRIVE. THANKS FOR ANY HELP THAT CAN BE PROVIDED!
Power hesitation, along with loud knocking sounds coming from the engine. Cause truck to completely shut off while driving 35mph. No warning lights or anything came on until complete failure
I was not personally at risk during my incident, but I can see how I could have been if my situation was a different. My 2021Chevy truck suddenly lost engine power at a traffic stoplight. It almost stalled coming to a stop. Then when trying to accelerate, it had very low power, and was stumbling. I was only a mile from home, and not busy traffic, so I managed to make it home. Driving very slowly with the engine clearly under very low power. No CEL or warning lights came on. After getting it towed to the dealer the next day, the dealer informed me it was a failed lifter and bent pushrod. After a little google searching, I found it is a common failure in newer GM V8s. I also learned my truck was built in a date window that GM issued a Service bulletin for lifter failures. According to forums and Facebook pages, Many other owners have had the same problem. Even 2-3 time failures with some owners. Even after repairs. Either in the date range of the bulletin or outside of it. My specific situation wasn't dangerous, but I could see how it could be, if I were on a busy highway, or if the truck completely lost power. As far as I see, no Recall has been issued, just many internal service bulletins over several years. And even a class action lawsuit in regards to lifter failure. My truck was fixed with all lifters replaced with an updated part number. 5000 miles since the repair. Gm did a good job with the repair, and after some communication with GM customer service, they replaced all the lifters, and not just the broken one. This gave me a bit more peace of mind, but I worry with so many failures posted online daily, and without a documented case on NHTSA this will continue. Thanks
I was on interstate 85 and the whole truck started shaking and check engine light, service ESC light and service parking brake light came on. Thankfully I was near and exit ramp and got off as I had almost no power. I limped my truck back to the dealership where they diagnosed it as lifter failure and replaced both banks of lifters. This is a known problem with General Motors and is simply a matter of time before a terrible accident occurs.
My pick up was hit from the rear the drive shaft broke at the well and the rear broke both side of the axle to the housing of the rear I have pick of the rear and the drive shaft.
At 7,316 miles my 2021 Silverado 5.3 V8 had lifter failure while driving, the truck would not accelerate correctly and I was forced to pull off the road, luckily it was able to turn off at the next road before the vehicles behind me caught up. The check engine light was blinking and was making a lot of popping noises. I was able to take back roads and drop it off at the dealership for repairs.
Vehicle began having issues at 3 months old... Random service messages, defective headlight, wierd engine noises at startup and stalling upon acceleration/deceleration. I took it to the dealer several times about the issues I were having but they always say they aren't able to replicate any issues. 3 months later I was driving on the highway and the engine started knocking. Had it towed to the dealer and it took them 6 months to replace engine, tcm, starter, and other parts. After finally getting the truck back, it was still stalling and there was a check engine light... Dealer did not reassemble the vehicle properly and several parts and bolts were still missing. It went right back in the shop and catalytic converters were replaced. I also mentioned missing parts and bolts. I get the truck back again and it still seems like it wants to stall. I was turning into a parking lot a few days later and it seemed like it wanted to cut off. While I was distracted trying to see if the truck cut off, I hit a small pole... Truck was damaged way more than it should have been because the dealer did not reassemble it properly. Body shop said my bumper was only held on by 2 bolts and several other bolts and pieces were missing. They said if my bumper was attached properly the damage would not have been as bad. The vehicle was already unsafe because of stalling and the dealer made it structurally unsafe as well... I have opened cases with gm and they aren't doing anything about it. Here this truck is 14 months old and it's been in their possession more than mine... I have asked them about replacing the vehicle and they insist on fixing the issues but never do and I end up driving an u safe vehicle around.
Add 1 more victim to the ongoing and growing list of GM owners of vehicles with 5.3/6.2Lmotors with DFM lifter failure. 50 miles after returning from a 500 mile trip from N. Wisconsin fishing trip this motor threw in the towel. Dealer assessment cylinder #6 lifter failure with an extra bonus of damage bad enough to require replacement of entire cylinder head! This motor has 11K. miles on it, and I have had oil changed multiple times as I am old school and don't buy into the whole 7500K. thing. Guess I should have saved my cash for something more fun! Check engine light did not come on till almost 2mi. after vehicle started running badly, flashing check engine light did not come on till I was almost home 15 mi. Had it towed to the dealer on my own dime!
Vehicle engine has experienced engine lifter failure at 28,000 miles. Engine began shaking violently, check engine lights flashing, traction control light, and stability control lights all came one while driving on the highway several hours away from home. Vehicle had to be towed by Chevy roadside assistance to the nearest dealership. Chevy dealership inspected and said they have to order new lifters for my engine and it would take several weeks for repair.
The 2021 silverado v8 randomly started making a knocking noise. The steering wheel would shake randomly as I accelerated and stayed above certain speeds. I-??m barely able to drive slowly residential speeds at most. If I drive any faster I-??m worried for my safety that the car while break down in the middle of a busy road posing a danger to my family and those around me. I-??m not sure if this is a lifter issue, or engine issue but it seems to be a widespread issue that I haven-??t recurved any recall notice for.
There is a massive shudder that sounds like the whole dash could come loose. feels and sounds like rumble strips and off road driving mixed all together. It happens at all speeds and when rpms are steady around 1200-1400.
I have a 2021 Silverado 6.2 being repaired for failed lifters. I see this is a common trend and can cause hazards when pulling over for a faulty motor. 10 speed Transmission downshifts from 2 to 1 harsh with rpms jumping up causing for me to apply more brake pressure to stop. I have had a few incidents when I get close to the vehicle in front coming to a stop. I have taken vehicle to dealer for issue and they couldn-??t replicate issues. Check engine light has popped up once or twice but never stayed on long enough to throw a code.
Engine valve lifter failure at 20,000 miles; engine hesitation and power loss. Error to parking brake and to electronic stability control. Chevrolet to replace damaged lifter but refused to replace both banks of defective lifters. As a result of dysfunction I was stranded 1200 miles from home and have been waiting 2 weeks for repair. Still 1200 miles from home with 2 kayaks, 2 bikes etc.
Driving down the road and out of know where engine starting knocking and lagging, idled rough. Drove to dealer lifter failure was what was diagnosed. 10000 miles on the truck driven easy, no towing or anything. Dealer also informed me 3 other silverados were there for the same problem! Ridiculous!!
Driving the vehicle on October 10, 2021, with my fiancee and her mother in the vehicle. Upon exiting expressway I-75 a noise in the front end could be heard. It was a pinging/clinking noise that didn't change in frequency under braking nor under speed changes. It stayed at the same frequency of occurrence regardless of speed but wasn't present at vehicle stop or idle. It seems only to happen when vehicle is in motion. The noise became louder at lower speeds of driving. Vehicle was taken to a GM dealership on October 11, 2021, for repair. The dealer indicated that they could not repair the vehicle as GM issued a work instruction (PIP5653) stating no repair or resolution is available. GM indicates there is no problem to the vehicle however something is wrong with the front end axle and if it breaks then there is risk of accident as the wheel could lock up causing loss of control and/or loss of steering. Upon reading document PIP5653 I learned that all GM full size pick-up trucks and SUVs from model year 2019 to 2021 are effected. This is a huge population at risk for possible loss of control and/or loss of steering to be supported by simple GM comment. There must be a fix.
