CHEVROLET Complaints

The contact owns a 2015 Chevrolet Equinox. The contact stated that while driving at an undisclosed speed, the vehicle started shaking abnormally before unintendedly decelerating. The vehicle was taken to the dealer, where it was diagnosed with excessive oil consumption; however, the vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 65,000.

The contact owns a 2019 Chevrolet Traverse. The contact stated that while shifted into park(P), the message "Shift to Park" was displayed on the instrument panel. The vehicle was taken to a local dealer, where it was diagnosed; however, the diagnostic result was not available. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 57,000.

On 04/28/2026, when diagnosing a reoccurring check engine light on the vehicle at a Chevy Certified Service, the mechanic "Borescoped cylinder 4 and found significant scuffs on the cylinder wall which along with the misfires indicate a cracked piston. The big picture appears to be the piston cracked which caused excessive oil consumption and misfires. The excess oil and unburned fuel overloaded the converter causing it to fail. The engine and converter will need to be replaced." In 2017, a recall was issued by GM to mitigate Stochastic Pre-Ignition (SPI) Causing Cracked Piston (17019). Between the initial purchase of the vehicle (11/2016) and performed service required by this recall (03/10/2017), there were approximately 5000 miles driven. No engine diagnosis was performed or recommended. After the 17019 was addressed, the engine misfires continued along with reoccurring CEL. C.S.P. N182195660 Predictive Monitoring for Stochastic Pre-ignition (SPI) released in 2019 states the 1.5 L LFV engines in certain 2016 and 2017 model year Chevrolet Malibu vehicles may have a preignition condition that requires immediate repair. This condition may cause the engine to perform poorly, misfire, run rough, and/or excessively consume oil. It may also illuminate the vehicle’s service engine light. Over time, if not repaired, the condition can damage the vehicle’s pistons and engine. The VIN for this Malibu was not attached to this notice despite it having SPI recall history. On 06/2023 (after the N182195660 program ended), at 80k miles a diagnosis revealed a potential cracked cylinder with no mention of the pre-ignition condition that could cause the crack, and the only way to fix is to replace the entire engine (as per dealer recomendation). Since vehicle was out of warranty, the repair est. was nearly $10k. I firmly believe my 2016 Malibu has suffered the consequences of poor mismanagement on this recall, and am demanding mitigation from GM to fix this issue.

I am experiencing multiple unresolved defects with my 2026 Chevrolet Equinox affecting drivability, braking behavior, and vehicle structure/fit and finish. The primary issue is a persistent vibration, shimmy, or wobble during moderate acceleration from a stop. This condition is felt through the steering wheel, seat, and floor, and occurs consistently during low-speed launch and normal acceleration. In addition, the vehicle produces a snapping or grunting noise during hard braking, as well as rough and loud movement noises from underneath the vehicle during normal operation, which raises concerns about braking and drivetrain integrity. There are also body and interior fitment defects. The front passenger door does not sit flush with the rear door panel and appears slightly open when closed. The dealership service manager stated that correcting this condition would require removing and pulling the rear door panel outward so both doors align. The glove box door also does not sit flush when closed, and the service manager advised that replacement might make the condition worse. These concerns were reported to an authorized Chevrolet dealer. The dealer confirmed that General Motors has acknowledged the acceleration vibration condition in a Preliminary Information service bulletin (PIT6466) affecting 2025–2026 Equinox vehicles and advised that GM engineering is investigating the issue and that no repair is currently available. The combination of drivability issues, abnormal noises during braking, underbody movement sensations, and body misalignment affects the use, value, and safety perception of the vehicle. The vehicle has very low mileage, and several of these issues have been present since early ownership. I am submitting this complaint to document these conditions and request that NHTSA monitor potential powertrain, braking, suspension, and vehicle structure concerns if a defect trend exists. All of these defects have been acknowledged by the Dealership Service Dept

While exiting a highway via an off-ramp, the vehicle experienced a sudden mechanical failure consistent with internal engine/bearing failure. During deceleration on the off-ramp, the engine began to shudder violently and immediately lost power. The vehicle was unable to maintain normal operation and became unsafe in an active traffic environment. After coming to a stop, the engine would not restart and the vehicle was completely inoperable. There were no prior warning signs or alerts before the failure occurred. The issue developed abruptly while the vehicle was in motion. The vehicle required towing and dealer inspection. Diagnosis confirmed internal engine damage / bearing failure / engine seizure. The repair required engine replacement This failure is consistent with widely reported issues involving GM 6.2L V8 engines (model years 2019–2024) experiencing bearing failure and catastrophic engine damage. The same failure characteristics appear to be present in this vehicle. This represents a serious safety concern due to the sudden and complete loss of engine power and inability to restart the vehicle while in a traffic environment, creating risk of collision or roadway obstruction. The vehicle had approximately 65,000 miles at the time of failure.

The car has cut off three time while at stoplights. I can get it restarted but the dealership cannot duplicate it even though there are codes in the system. Also the automatic braking will randomly stop when it shouldn’t and it is a hard braking.

Urgent: Engine Failure Following Recent Service – 2021 Chevrolet Tahoe To Whom It May Concern, I am writing to formally request assistance and an investigation regarding a serious engine failure involving my 2021 Chevrolet Tahoe. In July 2025, I paid out of pocket to have the lifters and camshaft replaced on this vehicle. More recently, while traveling, the vehicle broke down and was taken to Uebelhor Chevrolet, where the valve body in the transmission was replaced. After picking the vehicle up from Uebelhor Chevrolet, the vehicle broke down again approximately one hour later while in Henderson, Kentucky. At that time, the engine began smoking, running rough, and misfiring. I checked the oil level during the incident and found it to be extremely low on the dipstick (I have photographic evidence of this condition). The vehicle had to be towed to Kate Faupel Chevrolet for further inspection. I was then informed that the engine has a dropped lifter on cylinder #8 and possible camshaft damage. Given the following factors: Recent out-of-pocket lifter and camshaft replacement (July 2025) Immediate failure shortly after leaving a Chevrolet dealership Extremely low oil level observed at the time of breakdown (with photo documentation) Diagnosis consistent with potential oil starvation and internal engine damage I am requesting that General Motors conduct a full review of this situation to determine responsibility. This raises serious concerns about a potential defect, improper prior repair, or a service-related issue that resulted in catastrophic engine damage. At this time, I am not authorizing repairs until liability is determined. I am requesting: A formal case review and investigation Assistance with repair or full engine replacement Guidance on how this situation will be resolved This incident created a significant safety concern, as the vehicle became disabled shortly after leaving a dealership during travel. Please contact me as soon as possible to discuss next steps

Driver Information Centre (DIC) and Infotainment go dark. This has happened twice now over the last 2 months. While driving suddenly the infotainment goes blank and loses the radio and then the DIC follows by going blank (dark). So I was left with no speed indication. The car drives normally during that time. After 30 seconds to a minute the screens come back on as if it rebooted while driving.

The contact owns a 2016 Chevrolet Malibu. The contact stated that while driving approximately at 55 MPH in a rain storm and making a right turn, the ABS and Traction Control warning lights had illuminated, and the driver suddenly lost control of the steering and crashed into a tree. During the incident the driver sustained a concussion and neck and shoulder injuries which later required medical treatment. No police report was filed. The vehicle was later towed to the local mechanic. The cause of the failure was not determined. The manufacturer was notified of the failure, but no assistance was offered. The local dealer was not contacted. The failure mileage was 144,000.

Transmission has had a failure to shift problem on several occasions resulting in deceleration and a decreased ability to accelerate. This has occurred on most occasions at highway speeds while passing a vehicle causing a very unsafe condition. Dealer has evaluated and determined the transmission valve body is defective and needs replaced. Upon researching the problem, many similar GM vehicles are experiencing the same issue
