CHEVROLET Complaints

I have had experience with the "SHIFT TO PARK" error and I have had the "reduced engine power" error message resulting in an UNEEDED $2200 dollar repair only for it to break down 2 months later, same message this time with fuel spraying under the hood. I NEARLY BLEW MYSELF UP TRYING TO START MY CAR! How is it that I cant find this DANGEROUS defect on the recall list when I easily found the RECURRENT problem online? HELP

The contact owns a 2019 Chevrolet Traverse. The contact stated that while driving at an undisclosed speed, the vehicle jerked and failed to exceed 23 MPH. Additionally, the message “Shift to Park” was displayed upon parking the vehicle. The contact shifted out and in park (P) several times, and the vehicle responded as intended. Additionally, the contact stated that the vehicle failed to reverse. The vehicle was diagnosed by an independent mechanic, who discovered that the transmission fluid was leaking. The vehicle was then towed to the dealer, where it was determined that the transmission needed to be replaced. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 20V668000 (Power Train); however, the VIN was not included in the recall. The manufacturer was not made aware of the failure. The failure mileage was approximately 84,449.

On Star Telematics Module is failed and on backorder and no ETA according to dealership and ONSTAR. This is a safety issue as GPS is unavailable, SOS is unavailable, Cannot Locate Vehicle if lost or stolen. The company is very slow in response and this seems to be a global known issue.

Vehicle vacuum pump failed I have changed it 4 times now. Saw there have been more cases

Car says "service safety restraint system" and airbag light comes on intermittently. Dealer won't cover under safety restraint warranty. They site TSB about a wire that GM made too short but are not sure it will fix it. This car has 42,000. We are worried the safety restraint system won't work and we carry 4 children in our vehicle. This should be covered and a safety recall.

On 11-20-25 while driving vehicle home a loud noise was heard coming from rear of engine. After review and consultation with automative technician it was thought best to park truck in safe location at house and have towed to dealership as engine noise identified aligned with other reports of thrust bearing failures associated with this engine. Driving engine further was considered unsafe if further damage occurred the engine could seize up while on highway. The Dealership tested engine on 11-21-25 in accordance with GM technical service bulletin and confirmed a thrust bearing failure had occurred. A replacement engine and turbo were submitted for order, but not available to due to back order of these parts due to large number of failures of same engine this year. Only the GM dealership that I purchased car from has inspected vehicle at this time and there were no check engine lights in vehicle when failure occurred. I have since identified the GM technical service bulletin was published in September of 2025 and the Duramax 3.0 has had numerous failures throughout 2025, prior to my purchasing vehicle at end of October. GM manufacturing misrepresented the quality of vehicle during the new vehicle purchase and did not disclose the significant number of engine failures that have occurred this year that could have left me and my family in an extremely unsafe situation. Additionally there has been no communication on how the replacement engine equipment manufacturing has resolved the issue that created the initial failure and I am concerned of driving vehicle in future as the engine failure may occur again. NHTSA needs to record this incident and request to GM failure rate data this year and investigate GM for selling vehicles with known manufacturing issues that place driver/passengers in an unsafe condition when vehicle looses power while driving.

The problem that happened on my truck was the telecommunication module went out at 45k miles. That controls several features on my truck such as compass, navigation, remote start from cell phone, clock and several others. The biggest problem is that a check engine light pops up and you cant use your key fob to remote start your truck since the check engine light is on. I took it to the GM dealer to get fixed and they had to replace the module. According to my service advisor this is a common problem and I am looking for a recall or more information into why it failed.

On 10/14, I was driving the car to my job, when the car suddenly switched from its electric battery power to its internal combustion engine. The vehicle's information screen only showed that the battery was unavailable. I was able to operate the car on only the internal combustion engine to arrive at work. However, when I went to leave several hours later, the car would not start. The car was towed to a dealership and apparently repaired after about a week. However, the repair, a software reset, did not fixt the underlying issues, and on 10/27, after having the car for five days, the car again failed on my way to work, displaying a "Shift to Park" message and not starting. I towed the car to the same dealership, and they had it until 11/04. I recovered my car and drove it again to work that same day, but the car failed again due to the dealership not correctly diagnosing the issue, which appears to be the BECM, a failure related to bulletin N232432680. Due to this issue, I was left stranded on a busy highway for several hours on multiple occasions, and have not have a working vehicle since 10/14, meaning I have had to call off of work on multiple days, losing non-trivial amounts of income and undue economic hardship, due to this issue. Neither the dealership nor General Motors have offered any kind of help or support, and have generally attempted to avoid responding to my repeated phonecalls. Prior to this issue, there were no warnings or symptoms that I observed.

The contact owns a 2024 Chevrolet Corvette. The contact stated that upon parking and turning off the vehicle, the contact noticed that the radio, the infotainment screen, and the instrument cluster had failed to turn off. The contact stated that upon attempting to restart the vehicle, the vehicle failed to restart. Additionally, a tow truck driver was unable to jump-start the vehicle. The vehicle was towed to a local dealer, where it was diagnosed and determined that the 12-Volts battery needed to be replaced. The vehicle was repaired; however, the failure recurred approximately 3 weeks later. The vehicle was driven back to the same dealer, where DTC: U164F was found, and the dealer reprogrammed the infotainment system. The vehicle was repaired; however, the failure recurred recently. The vehicle was driven back to the same dealer, but had yet to be diagnosed or repaired. The manufacturer was informed of the failure and offered to buy back the vehicle; however, the manufacturer later withdrew the offer. The failure mileage was approximately 500.

My 2019 Chevrolet Tahoe Premier equipped with the 6.2L V8 engine has experienced a major internal engine failure. The dealership diagnosed camshaft bearing failure with a recorded misfire on cylinder #5. The engine oil was drained and inspected and no significant metallic debris was found, and the dealership noted no evidence of abuse or neglect. Intermittent drivability concerns were present over the life of the vehicle and were addressed through professional diagnosis and repair each time. The vehicle has been properly maintained since new. Just months prior to this failure, the vehicle underwent full diagnostics and significant repairs, and no internal engine failure was identified. This failure appears consistent with a known defect pattern affecting GM 6.2L engines involving internal valvetrain or camshaft-related failures. The failure resulted in abnormal engine noise, misfire, loss of power, and the vehicle becoming unreliable for safe operation. General Motors has declined goodwill assistance citing warranty expiration, despite the nature of the failure being a non-wear internal engine defect. I am submitting this complaint so this VIN and failure can be reviewed as part of any ongoing investigation into 6.2L engine failures.
