CHEVROLET Complaints

My truck has the L87 motor on recall. i purchased it brand new and paid top dollar for it. I've had issues since I've bought it. All of my maintenance has always been done at the dealership from regular maintenance to purchasing brand new tires. I am very disappointed to have a truck that concerns to drive, i do not take my family out in my truck because i am not confident in its reliability and safety. multiple times i've taken my truck in for service and let them know to complete an oil change, tire rotation and to check an issue with a "tick, clunk and knock" just to be told it was "normal for the 6.2". my normal dealership has blocked off appointments online and you'd have to call to try to set one up. I demanded a diagnostic one time when the truck was acting weird and the tech stated "stop by, i'll squeeze you in" in which i did. however, i wasn't given any documentation since "i didn't have an appointment". After reviewing all of my service records, i come to notice not once time did they mention they did a diagnostic check. Only the recall test shows on one of the service records. I've had 3 different viscosity oils in my motor from the dealer stating GM recommended it. I had to night drop my truck on June 14 as it was making a weird noise from the engine and it felt like it had less power. I waited 2 days and the dealer did not contact to even state they have my truck in service. when i called to ask the status i had to agree to text message communication in which they replied, "at best it will take 2 weeks just to look at it". I asked for a loaner since i need a truck for work and transportation, they replied they do not have any and I will be placed on a list. My truck is still under original powertrain warranty and they cannot even provide a loaner. i feel that they are brushing me off to buy time and here i am making hefty car and insurance payments for a truck i do not have nor a truck that I NEED to provide for my family. GM does not care!

The power steering motor failed ,ESC , TRACTION and power steeringg lights came on, i am a woman and coould NOT control the car and my safety and others was at risk for an accident or crash ,there was nothing prior to this just suddenly loosing control of my car and a very scary position to be in , yes the chevy dealer has the component.I know ther was a recall on this problem and other s beside myself are still having this problem so with the low milage on this car this should NOT have happened , General Motoors should stand behind a recall no matter how long, a recall is a recall 10 years or the life off the car.

Our car one day showed several illuminated dash lights regarding brake system, along with several pop up warnings. We took it to a Chevrolet dealer for service. They’ve had it for 54 days. They’ve confirmed widespread brake system and electrical system failure, but even after escalating to corporate tech assistance, there is no progress nor resolution available. We were told they have at least a dozen others with this same issue. It is wildly inappropriate that there has not been a recall issued as this is a serious safety defect. We demand a buyback from GM for putting this death trap on the market knowing they had these issues with 2024 models but continuing to roll 2025 and 2026 models with the same issues.

I am filing this complaint regarding a major engine failure in my 2020 Chevrolet Silverado 1500 equipped with the 5.3L V8 engine. At approximately 56,000 miles, my vehicle experienced a failed valve lifter, resulting in loud engine ticking, a check engine light, loss of power, and unsafe driving conditions. The vehicle was no longer operating properly and required immediate repair. Although the vehicle had been regularly maintained and had relatively low mileage for such a significant engine issue, I was informed that the failed lifter damaged the camshaft and related engine components, requiring extensive repairs. The total cost of the repair was $6,180, which I paid out of pocket. My Silverado was just outside Chevrolet's 5-year/60,000-mile powertrain warranty period by time, despite having only 56,000 miles. A major internal engine failure should not occur on a well-maintained vehicle with such low mileage. After researching this issue, I discovered that lifter failures involving the Active Fuel Management (AFM) and Dynamic Fuel Management (DFM) systems in GM's 5.3L engines have been widely reported by other Chevrolet Silverado owners. This indicates a potential design or manufacturing defect rather than normal wear and tear. I am requesting that General Motors provide reimbursement or goodwill assistance for all or a substantial portion of the $6,180 repair cost. I believe customers should not be responsible for paying thousands of dollars to repair a known issue on a low-mileage vehicle. I respectfully request that this matter be reviewed and resolved promptly.

“Service transmission now unable to shift soon” message. Vehicle is stuck in park. Message appeared in May. Transmission stuck shortly after. Safety is at risk due to transmission being unable to shift due to faulty module that is widely reported and known to Chevrolet.

Rear end makes noise when turning, been flushed based on current bulletin. Still makes noise but not as bad. Now transmission is jerking at multiple gears

2018 Chevy Traverse purchased from Carvana caused carbon monoxide exposure to my family in military housing. Vehicle locked itself while running in the garage (garage door open), and CO entered the home where my children were standing near the interior door. Fire dept forced entry into the vehicle and cleared the home. All family members required oxygen at the hospital; all 3 children had elevated COHb levels. Mechanic confirmed catalytic converter failure and exhaust defect. Full Description: On 6/7/26, our Traverse turned on and locked itself while running in our garage (door open) as we were preparing to leave. Exhaust was blowing toward the interior door of our military home, and CO entered the house. My children were inside near that door and became exposed. We could not unlock or shut off the vehicle. Fire dept forced entry, confirmed high CO levels, and cleared the home. At the hospital, all of us required oxygen; all 3 children had elevated COHb. A mechanic later confirmed catalytic converter failure, exhaust defect, P0171, and incomplete catalyst monitor—stating this can cause ongoing CO exposure. A Build Verification sheet found in the glove box (not disclosed at sale) showed pre-existing issues: exhaust rattle, check engine light, and multiple mechanical reworks. Carvana refuses to assist. This vehicle is unsafe to drive or idle.

Service brake assist warning came on the day before a severe audible engine knock started. Drove to nearest dealer and they immediately diagnosed as a probable engine failure/engine bearing/connecting rod. 6.2 liter engine 9500 miles

Fuel regulation module K111 part number GM13540028 failed and when this part fails the truck is stuck where it is. The brakes are locked, the truck cannot be started or put in neutral. If the truck stops on the road or freeway you are completely stuck where you are in the middle of traffic. This part fails often and failure leads to a very dangerous situation.

General Motors is using the arbitrary 6,213-mile tracking window of Recall 944 to deny coverage for a diagnosed Cell Section 3 hardware failure at 123,582 miles. However, this vehicle is directly impacted by the failure parameters outlined in the expanded GM Safety Recall N242470160 / N242470162, where GM openly acknowledges to federal regulators that the advanced diagnostic software has failed to properly detect defective battery modules. By denying a physical battery replacement when a manufacturing defect is caught during a mandatory corporate software reconfiguration, GM is violating the spirit and legal intent of their ongoing federal safety recall campaigns.
