Warnings problems of the 2024 Chevrolet Traverse

Vehicle experienced uncommanded automatic emergency braking with no warnings or obstacles present. Sudden hard braking caused fear of collision. Children were in vehicle as well as two adults. Vehicle has prior collision repairs. Owner fears highway driving due to risk of recurrence.

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.

To date, I have brought the vehicle to the service department four times, primarily due to the check engine light and other critical malfunctions. Below is a summary of the incidents: first visit (approx July 2024): the vehicle suddenly lost acceleration while I was in traffic, leaving me stranded in the roadway. This posed a serious safety risk. The vehicle remained in the shop for 28 days. Second visit (September 29, 2024): multiple warning lights illuminated, and several diagnostic codes were detected. Third visit (do not recall the issue): will find work orders if needed most recent visit (December 3, 2025): a coolant leak caused the temperature gauge to spike, resulting in the air conditioning shutting off due to overheating. The next day the check engine light came on. I had no warning prior to the guage spiking. In addition to these major issues, the following concerns remain unresolved: brakes continue to squeal. The dealership advised this is normal and that front brakes wear faster. Reverse sensor activates randomly, causing the brakes to engage abruptly. Also the front crash sensor triggers without any obstruction ahead. The dealership recommended disabling this safety feature. These recurring problems raise serious safety concerns and significantly impact the reliability of the vehicle. The advice to disable safety features is unacceptable and does not address the underlying issues.

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 NHTSA to record this complaint and evaluate whether these failures represent a broader safety defect in the 2024 Chevrolet Traverse z71.

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.
