I keep loosing power and get the message "Engine Power Reduced" and the car stops while driving down the road, sometimes it just stutters and won't maintain speed without the warning. I've had 2 shops check it out and can't find anything wrong. This vehicle has had all required maintenance done by the dealer since it was new.

1. The vehicle's transmission does not operate consistently and safely. 2. At times, the transmission will not engage, and this has placed my family in very dangerous situations when changing lanes. 3. At red lights, at times, the transmission will not engage to drive. 4. When slowing in traffic at times , the transmission will not adjust to the slower speed, although the operator is applying the brakes. Then, without warning, the transmission will engage the higher speed, almost launching the vehicle forward suddenly, potentially into another vehicle or person, depending on the situation.

Vehicle Safety Complaint – 2024 Chevrolet Equinox I am reporting a safety defect involving unintended vehicle movement and improper shutdown behavior. While operating my 2024 Chevrolet Equinox, I was able to shut the vehicle off even though it was not in Park. After shutdown, the vehicle rolled forward on its own and struck a tree. At the time of the incident, the radio remained on despite the vehicle being turned off, indicating the vehicle may not have fully entered ignition-off state. This incident suggests a potential malfunction involving one or more of the following systems: gear position detection system transmission park engagement mechanism electronic shift control module ignition state logic or body control module The vehicle should not allow shutdown unless it is in Park, or it should provide clear warnings and prevent unintended movement. This behavior presents a serious safety risk of rollaway incidents. I am requesting a full diagnostic inspection and documentation of all stored fault codes, including history codes, prior to any resets. Please also check for software updates, technical service bulletins, or known defects related to shift position recognition or ignition state control. This issue resulted in unintended movement and property damage and poses a significant safety hazard.

The contact owns a 2024 Chevrolet Traverse. The contact stated that while driving out of the dealer's parking lot at 4-5 MPH and depressing the accelerator pedal, the messages "Service ESC System" and "Brake System Failure - Press Hard to Brake - Do Not Drive" were displayed, and the check engine warning light illuminated. The contact stated that the vehicle failed to respond while depressing the brake pedal, and the vehicle rolled to a stop. The vehicle was taken back to the dealer, where the failure was associated with the braking system. The dealer disconnected and reconnected the battery, and the dealer cleared the codes. The dealer informed the contact that the vehicle was repaired and returned the vehicle to the contact; however, the contact stated that the dealer had failed to determine the cause of the failure and to perform an adequate repair of the vehicle. Additionally, the contact stated that the brakes had been making an abnormal squeaking sound while the brake pedal was depressed. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure, and a case was filed; however, the contact had not yet been contacted. The failure mileage was 16,876.

My check engine light came on, I took my vehicle to Ken Ganley Chevrolet because that is where I purchased it. They claim they have no record I bought it there and at first refused service. I provided my loan documents that state I purchased it. Tim was in the service department, I brought the car in and he had it looked at. He said the issue is the turbocharger, which is a known issue with this year/make/model that GM knows about. The repair was under warranty, completed and the car returned to me. Less than 2 weeks later the check engine light came on and the diagnostic gave the same error. I took it back to the dealership and I got 3 different answers. One person told me it was an exhaust issue that was causing the turbo to overheat (the car is kicking out excessive amounts of carbon monoxide), the second person told me there was no issue and they weren't sure why the check engine light went off, the third person said it seemed like the exhaust and the overheating was a safety issue and it shouldn't be driven. They ultimately refused the repair and said bring it back if it gets worse. I called GM corporate to report the dealership and ask for an actual repair. They told me to take it to another dealership to be looked at. Multiple other dealerships have refused because the case is open with the original dealership. That Ken Ganley Chevrolet dealer is refusing to acknowledge a repair is needed. The car is continuing to kick out excessive carbon monoxide and smells like burning when driving. The engine chugs and doesn't get up to full speed. I requested goodwill reimbursement for part of the car from GM for failure to service and an unsafe vehicle and they have offered no solution because other dealers won't give a second opinion. The car is not safe to drive and is not being repaired.

On approximately January 24, 2026 my 2020 Chevrolet Silverado 2500HD equipped with the 6.6 Duramax Diesel displayed an error code (P20B9). This error code was found to be related to the diesel exhaust fluid system specifically relating to "Reductant Heater A Control Circuit/Open." On January 27, 2026, the vehicle was diagnosed at Chevrolet dealership and the following was reported "Diesel Emissions Fluid Tank Remove and Replace - P20B9 SET FOR REDUCTANT HEATER CIRCUIT...COMMANDED ON AND ZERO AMPS..CIRCUITFAILURE... DISCONNECT PUMP MODULE AND BURNED/OVERHEATED TERMINALS..PUMP MODULE AND HARNESS PART OF TANK ASSEMBLY... LABOR TIME ADDED TO PERFORM MALFUNCTION/TAMPER TEST TO CLEAR EMISSIONS MESSAGE...." I found the "burned/overheated terminals" comment to be alarming. I looked into this matter further and found a GM Service Bulletin (21-NA-006) from October 2022. This bulletin identified this issue which contained an image showing burned/overheated terminals. The identified cause within the bulletin states "This condition may be caused by a poor connection at the Emission Reduction Fluid Tank electrical connector." I believe this should upgraded to a safety recall due the the potential of this terminal connection catching fire which could be detrimental for the operator, passengers, property, and the public.
