CHEVROLET Complaints

My 2017 Chevrolet Tahoe equipped with a 6L80 transmission began experiencing transmission-related drivability issues at approximately 130,000 miles. The vehicle jerked on takeoff, had delayed/slow shifting, produced a whining noise, and later had intermittent shuddering/surging while driving. During service, metallic debris/shavings were found in the transmission fluid. The transmission ultimately required replacement at my expense. I am aware of GM Technical Service Bulletin 20-NA-142, “Shudder/Surging While Driving,” which includes 2015–2022 Chevrolet Tahoe models equipped with MYC/MYD transmissions and discusses conditions that may be identified as torque converter shudder. My vehicle’s 6L80 transmission corresponds with GM RPO MYC, and the symptoms/repair findings appeared consistent with the bulletin. I am filing this complaint to document the transmission failure and related safety concern, as the jerking, delayed shifting, and shuddering affected normal vehicle operation.

Driving 65mph down highway and power steering lost power and Error message "Stabilitrak" "Power steering drive with care" This is a busy highway and I was scared I was going to crash into another vehicle or run off the road. I have taken this vehicle immediately to my Chevy dealer and was told it was my rack and pinion needed to be fully replaced. I checked the recall list and my vehicle was not listed , however GM recall N202325410 for the 2015 Colorado has the same components and parts was involved in a recall.

My 2023 Chevrolet Suburban Premier is covered under GM recall 25V-274 for the 6.2L L87 engine defect (loss of propulsion from connecting rod and crankshaft failure). In XXX, the dealer notified me my vehicle required a full engine replacement under this recall. Wareing Sheridan Chevrolet in [XXX] replaced the engine, and the vehicle was out of service approximately 12 to 14 days. Approximately 6,000 miles later, on XXX, the replacement engine failed while I was driving on the interstate highway near Billings, Montana. There were no warning indicators of any kind until I suddenly lost power. Only at the moment power was lost did the check engine light come on and a low oil pressure warning appear. I was barely able to get the vehicle off the interstate before it died. I had my family in the vehicle, and losing power on the interstate with no warning created a serious risk of a crash. The vehicle had to be towed to Denny Menholt Chevrolet in Billings, MT. On June 13, 2026, the dealer confirmed the vehicle needs a second complete engine replacement under the same recall. This is the second L87 engine failure and second full engine replacement on this vehicle under recall 25V-274. No crash or injuries occurred. I have an open case with GM (#XXX).

I used the jack for the first time of buying the vehicle new. I jacked the vehicle up to put the spare on and the scissor jack folded up and the car dropped. So I looked up if there was a recall on it and there isn't but there is on other vehicles. Note: the car was on level hard surface ground and I placed the jack in the correct location.

Defect: Engine failure caused by lifter and camshaft failure at 114 miles (5.2 engine hours). The vehicle is at the dealership undergoing warranty repairs. The service department confirmed a seized lifter, necessitating the replacement of all lifters and the camshaft. The incident occurred at highway speeds on the interstate when the engine suddenly began knocking loudly. Immediately after the knocking started, the check engine light illuminated, followed by consecutive "Service Anti-Collision System" and "Service ESC (Electronic Stability Control)" warning messages.

I was driving on the highway at about 70 mph and the passenger side lower control arm where the ball joint sits broke. It messed up the passenger fender and tire along with the steering link. It also bent the upper control arm as well. The ball joints were replaced about 6 months ago.

Vehicle engine light came on XXX and was driven immediately to Auto Zone to check the code. The code showed P0299. The vehicle was then taken 2 miles home and parked. It was towed to Lake Chevrolet in [XXX] on XXX to prevent any engine damage from occurring due to the failed turbo. Upon Lake's inspection they claim the manifold and valve cover gasket must be replaced. We agreed to that, and asked about an oil change as everything we read said that was mandatory with work like this. Was told the technician didn't suggest it but they would do it at our request for an additional charge. After they confirmed the turbo was bad and well as the items above we agreed to the repairs and they said the vehicle would be ready the next day. We called again at the end of the next day and they said the repairs were made and they were going to drive the vehicle to make sure all was well. The next call we received was the service advisor stating we need a new engine as after they drove it white smoke was coming from the exhaust and they now found a cracked piston. The vehicle was not blowing out white smoke when they received, it also passed emissions on 4/14/26. We also asked for all technician notes, diagnostics, etc. which they will not provide us unless we come in and get the non running vehicle and pay the 983.00 invoice. We would have to have the vehicle towed from their lot as it can't be driven since their repairs. We contacted GM and spoke with "Tamar" multiple times with no resolution. Service manager claims GM will pay 1,500.00 towards a 9,000.00 new engine. This engine damage is consequential damage of the turbo failure which the dealership is denying. GM and Lake Chevrolet are refusing to honor special coverage XXX for the resulting catastrophic damage. Dealership also refusing to provide documentation requested in attached letter. We seem to be expected to take their word for all of this. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Driving towards direct light/sunlight is damn near impossible with this vehicle die to the extreme amount of glare from the dashboard. It makes me worried especially now that summer is approaching, feels like it can be catastrophic. Rear brake assist is horrible on more than one occasion the car will stop as if it has just been hit by a semi. Leaving the vehicle unable to proceed in reverse(one has to shift to drive or put in park before continuing to reverse). This is not only a nuisance but can lead to an accident especially during the mad rush of drop off at the elementary.

Was traveling to head towards the beach and all of a sudden the whole dash starts glitching then goes out for about 10-25 seconds then cuts back on like the car is powering back on. I thought maybe it had something to do with my daughter touching the radio. Well I continue to travel get down the road about another 45mins and it does it again. So I decide to turn the radio off, turn off the A/C, call the dealership and turn around and go home. Dealership checks the car, states it may have been the radio. But how when the car seem to lag/ lose power for a few seconds. That's a safety issue. Car can cut off and cause catastrophic damages. I only drive 3 miles to my job daily so I don't know if it'll happen again until this weekend when I travel to Florida. I've had Dealership to replace the antenna when I first got the vehicle because radio wasn't working. I constantly hear a clicking sound when the air is on. Dealership states they don't hear it. This model vehicle seems to have a few kinks that need to be check.

2021 Chevy Suburban started to have harsh shifting particularly on acceleration and shuddering at higher rates of speed (feeling like you are driving over a rumble strip). I took it to the dealer, and they confirmed the torque converter was in the process of failing. It's currently in the shop getting a new torque converter. No warning messages/lights had yet appeared. Technician at dealer stated that this was a common failure with this model.
