2024 Chevrolet Traverse

The Defective Software Trigger: vehicle’s dashboard Brake Pad Life Monitor indicated the pads were low showing 19% roughly 3.5-4mm remaning life. Upon arrival to the dealership, I was informed that my rotors would also need to be resurfaced. I contested a mandatory rotor resurfacing policy. I openly disagreed with this arbitrary "store policy" but was forced to comply to get my vehicle serviced. The dealership stated they would refuse to replace the pads unless I paid out-of-pocket for an unnecessary resurfacing. The technician measured my pads at 7mm (over 60% of usable life remaining). My vehicle did not need brakes; it was suffering from a known factory software bug detailed in GM Bulletin 25-NA-029. Rather than identifying this warranty glitch, I was forced to pay for unnecessary vehicle repairs. The technician machined my front rotors and installed new pads. On my way home, the vehicle exhibited severe, violent steering wheel shaking under braking at highway speeds. The technician completely failed to check for runout or machine the rotors evenly. I was forced to drive 90 miles home with a violently vibrating steering system. I called the dealership but the facility was closed. To correct a severe safety hazard caused entirely by the shop, I had to drive an additional 90 miles back to the dealership (a 180-mile total round trip) on compromised brakes. I requested that the dealership replace the ruined rotors and pads at their expense. Management refused instead, to force the shaking to stop and avoid paying for hardware, the dealership refunded the original resurfacing fee (Driver side rotor 29.89mm to 1st resurface 29.20m- Passenger side 29.80mm to 1st resurface 29.25mm) and machined my front J61 rotors a Second time, cutting them down to 27.80mm Driver side and 27.59 mm on my passenger side. I have contacted corporate but I've had no resolution.

There was a sent out that GM dealers needed to at no cost provide the software update to several vehicles due to a software issue that puts out an emergency warning that the brakes are wearing and are critically low when in fact they are not. Without the new software vehicle owners cannot manually reset the notification even after changing their brakes. I recently took my truck to David Chevrolet who advised me I needed to pay $193 for this software update which goes against the notice from GM and the DOT. I’m now driving without my brake monitoring system on because the dealership will not update my software. I’m filing a complaint because I should not need my brakes changed again by the dealership as I have already replaced perfectly good brakes because I didn’t know there was a software problem. My vehicle is well under the 36k mile and is only two years old.

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.

There is a known issue with the software / brake monitoring system with the 2024 Chevy traverse. The brake pad sensor is faulty and the vehicles warning system tells you that your brake pads are critically low when in reality they are not. Even after you change the brakes and put a new sensor you cannot clear the notification. The only way to reset this is to either take it to the dealership for them to change your brakes or pay $200 to obtain the fix for the software. Now this is bricks maintenance meaning as the consumer you should be able to maintain your vehicle on your own but GM has made this impossible which will force the consumer to turn off their brake monitoring system to remove the faulty warning. This is a safety risk for the consumer and the other people on the roads. This update should be done free of charge but they refuse to do it.

VEHICLE: 2024/2025 Chevrolet Traverse RS COMPONENT: Electronic eBoost Brake Master Cylinder Assembly DESCRIPTION: Within a few months of purchasing the vehicle, the brake pedal began exhibiting excessive free play (long pedal travel) and significantly delayed stopping behavior, particularly dangerous at highway speeds. The vehicle requires substantially more stopping distance than normal, creating an imminent rear-end collision risk. This defect has been brought to the dealership's attention twice already. The vehicle was just serviced and returned for this same issue. After each service visit, the brakes temporarily function normally for only 500 to 1,000 miles before the dangerous delayed braking behavior returns. Previous dealer repairs included bleeding the brake lines and updating the Electronic Brake Control Module (EBCM) software — both failed to permanently resolve the issue. The root cause appears to be an internal bypass leak within the electronic eBoost brake master cylinder assembly, where defective internal rubber cartridge seals allow pressurized fluid to slip past them over time, progressively degrading braking performance until the next service intervention. This is a REPEAT safety failure. The vehicle has been serviced for this identical brake defect TWICE, and the condition returns each time within 500–1,000 miles of the repair. This issue is documented under GM Service Update N242482170 and TSB 25-NA-029, and is the subject of active class-action litigation affecting 2024–2025 GM SUVs. The driver and all vehicle occupants are placed at serious risk of injury or death due to the inability to stop the vehicle within a safe distance during normal highway driving conditions.

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.

My breaks have been squealing on my 2024 Traverse since about 6 months after my purchase in 2024. I have taken it to the dealership on multiple occasions and they stated that GM knows of the issue but there is no fix. The system states my front breaks are low. I recently took my Traverse to a break repair/replacement shop and they stated my breaks are not low and they look great and numerous people have brought their Traverse in with the same squealing complaint. With the amount of complaints why hasn't GM done anything about it?
