When I am in reverse, the car will slam on the brakes without warning even without a hazard or object in the way.

A software update caused the warning lights to go on and off despite no issues surrounding the vehicle (lane assist, forward collision warning). While driving on the interstate going 70MPH the forward collision light flashed a warning which then reduced the cars speed from 70MPH to 40MPH within a very short period of time. This is a huge safety concern and no accident happened as there were no other vehicles around at the time.

I am writing to express my disappointment with the quality and reliability of my vehicle. Since purchasing it, I have had to return it to the dealership on five separate occasions due to ongoing defects and mechanical issues. Shortly after purchasing the vehicle, the Super Cruise system failed to function properly and required service. At approximately 15,000 miles, I was informed that the brake pads were already excessively worn and needed replacement, which I believe is premature for a vehicle with such low mileage. Most recently, the check engine light illuminated, requiring another visit to the dealership for diagnosis and repair. These repeated issues have caused significant inconvenience, wasted time, and disrupted my daily life. I purchased this vehicle expecting it to be safe, dependable, and of high quality. Instead, I have experienced recurring problems that have seriously affected my confidence in the vehicle. Given the number of repair visits and the ongoing defects, I respectfully request that General Motors review my case and provide an appropriate resolution. I would appreciate a prompt response and a fair remedy to address these continuing issues. Thank you for your time and attention. I look forward to hearing from you soon.

Vehicle: 2024 Chevrolet Traverse Z71 Mileage at first incident: 25,821 My 2024 Chevrolet Traverse Z71 experienced multiple safety‑critical electrical and ADAS failures. The vehicle had a Reduced Acceleration / limp‑mode event, accompanied by a strong antifreeze odor inside and outside the vehicle. Dealer diagnostics on 06/29/2026 and 07/16/2026 confirmed several trouble codes affecting the engine, braking system, and collision‑avoidance systems. The following diagnostic trouble codes were recorded: P3705 – Engine Coolant Pump Control Circuit Low (engine cooling fault) C0609 – Park Brake Actuator / Switch Signal Fault (brake system logic fault)-Active 6.29.26 10:12:43AM U160A – Lost Communication With Serial Data Gateway Module (CAN‑bus gateway failure)-Active 6.29.26 10:12:43AM U197A – Lost Communication With Front Radar Sensor Module (forward collision warning / AEB disabled)-Active 6.29.26 10:12:43AM These faults caused loss of radar‑based safety features, including Forward Collision Warning, Automatic Emergency Braking, and Adaptive Cruise Control. The vehicle displayed warnings and temporarily disabled ADAS functions. The Reduced Acceleration event created a hazardous situation in traffic. The dealer attributed the incident to “low coolant,” but the diagnostic codes clearly show electrical and communication failures across multiple safety‑critical modules. The antifreeze odor continues, suggesting a possible coolant leak or unresolved cooling system issue. The vehicle has been inspected by GM technicians, and the codes were documented on both visits but they say car is fine. The safety systems affected include brakes, engine cooling, electrical CAN‑bus communication, and collision‑avoidance radar modules. I am requesting the federal safety agency to record this complaint and evaluate whether these failures represent a broader safety defect in the 2024 Chevrolet Traverse Z71.

The 2024 Chevy Traverse has super cruise. It is basically an auto drive feature. It has sensors in the top part of the steering wheel. This plastic area is known for cracking and the dealership said there is nothing they can do. This is absurd. They know there is an issue with the wheels cracking and they are not fixing them under the warranty.

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.

I am experiencing a recurring battery/charging system detection warning with my vehicle that has not been resolved despite multiple service visits. The warning continues to reappear after the vehicle is returned to me, indicating the issue has not been properly diagnosed or repaired. My vehicle has been in the shop approximately 5 times for this same issue. Each time, I am told the problem is resolved or that they cannot replicate the issue, yet the warning returns shortly afterward. To date, no permanent fix has been provided, and the underlying problem has not been remedied. I have made repeated attempts to work with GM and the dealership, but meaningful assistance or escalation has not occurred. This ongoing electrical issue raises concerns about the reliability and safety of the vehicle, as well as GM’s failure to correct a known, documented problem. I am requesting appropriate escalation and resolution, including further diagnostic intervention by a regional service manager or field engineer, or consideration of alternative remedies if the issue cannot be permanently repaired.

Recurring failures related to brake system. When reversing, the rear brake assist system slams on the brakes for no reason even though no obstacles are present. This startles everyone in the vehicle and nearby traffic. On other occasions, the vehicle shows an error on the instrument cluster stating "Rear Brake Assist Unavailable". More recently, a persistent error began appearing on the instrument cluster stating "Service Brake Monitor", indicating a failure of the brake pad sensor. On top of all of this, the brakes are noisy and squeaky to the point where it wakes up my neighbors.
