2024 Chevrolet Traverse

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 NHTSA 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.

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.

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.

The 2024 Chevrolet Traverse includes Front Pedestrian Braking and Rear Cross Traffic Braking as part of its standard Advanced Driver Assistance Systems (ADAS). However, these systems tend to malfunction on rainy days when the sensors become wet. In such conditions, the vehicle may brake abruptly even when there are no hazards in front or behind. For example, while attempting to drive around a vehicle waiting to make a left turn at an intersection, my Traverse suddenly stopped in the middle of the intersection, incorrectly detecting a potential collision. Another frequent issue occurs when backing out of my driveway on rainy days. The system applies the brakes, mistaking raindrops for obstacles. Due to these recurring problems, I have deactivated the safety systems and now drive without them enabled. This situation not only creates inconvenience for me as a driver but also poses risks to other road users if the vehicle stops unexpectedly in traffic. Additionally, repeated hard braking can lead to premature wear of braking components.

"Phantom Braking" with over 13 events the 2024 CHEVROLET TRAVERSE LT unexpected and abrupt activated the Automatic Emergency Braking (AEB) system when there was no obstacle, vehicle, or collision risk present! If an Mac Truck was behind us tailgating at the time we would have been killed! The dealer is downplaying the issue acting like they have never seen this before. They question is we know what AEB is and how it works "WE DO!". On top of that the 2024 CHEVROLET TRAVERSE LT breaks are completely defective. Deal inspected them on 6/25/2025 then we purchased on 8/14 drove it for 2,290 miles and they claim the breaks needed replacement. So we paid for that and still the breaks make a bad grinding sound and it is hard to stop the SUV. Please investigate ;(
