2024 Chevrolet Traverse Brakes Problems

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?

I took my vehicle in several times for issues regarding the brakes. I was told for months nothing was wrong. The brake percentage was rapidly declining on the display and they just kept saying it would fix itself in an update. Finally the service brake alert came on prompting me to take it to the dealership again for the brakes. I was told my front brakes were completely gone and needed new pads and rotors and my back brake lines were severed and pouring brake fluid everywhere. I was told I was lucky I brought it when I did because I could have gone to stop and just not been able to. It was concerning because there was no warning or indication there was anything wrong and I kept being told everything was fine

At purchase, I noticed that the brakes felt spongy and were screeching when the salesmen pulled up. The salesmen stated that new brakes always screech due to burned plastic. Weeks later, I scheduled a servicing appointment with Chevy Crews in North Charleston, due to brake screeching, the repairmen told me again that the brakes had condensation on them, so he dusted them off and the screeching would stop in 3 weeks. 3 weeks later I returned again, the salesmen told me that GMC made the vehicles with faulty brakes. My vehicle was seen over 4 times for screeching brakes, thousands of consumers have complained about the same issue, and GMC has failed to act.

Approximately four weeks ago on 02/03/2026, during rainy conditions, the brakes on the vehicle did not function properly, creating a serious safety concern. At the same time, a hose connected broke and there was a strong burning smell coming from the vehicle. I also noticed fluid leaking from the vehicle. I immediately took the vehicle to the dealership for repair, and the vehicle remained there for approximately five days for inspection, parts, and repair. Additionally, this is now my third time bringing the vehicle in for service. During previous visits, I asked the service department about the condition of my brakes because they were making a squeaking noise and I was concerned about their performance. I was told by the service department that the brakes were fine, that I still had plenty of brake life remaining, and that the squeaking noise was normal. However, as of March 4, 2026, my vehicle displayed a new warning message stating “Service Brake Pad Monitor – Front Brakes.” This is concerning because the vehicle currently has approximately 25,490 miles. Given the previous brake concerns I reported and the dealership’s response that the brakes were normal, the new warning message raises additional concerns about the safety and reliability of the braking system. Because this defect involves the braking system and creates a safety concern, I am requesting that General Motors review my case under the applicable Lemon Law and advise me on the next steps toward either a vehicle replacement or buyback if the issue cannot be fully resolved.

What component or system failed or malfunctioned, and is it available for inspection upon request? The front and rear brake system is malfunctioning. Both front and rear rotors have developed significant premature heat “hot spots,” causing loud, persistent squealing and excessive heat from the front wheels. It began with the front brakesm July 2025 and as of October 2025 the rear brakes had the same issues. This vehicle is available for inspection upon request. ----- How was your safety or the safety of others put at risk? This issue involves the primary braking system. The front and rear brakes become excessively hot and produce loud, constant squealing. I am concerned about potential brake drag, caliper malfunction, or premature rotor damage, which could reduce braking efficiency or lead to brake failure. Because this affects stopping performance, it presents a potential safety risk to myself, passengers, and others on the road. ---- Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The Chevrolet dealership confirmed that both front and rear rotors have heat hot spots and advised replacement of the rotors and brake pads. Although I replaced the front break parts as suggested this did not repairthe issues. The vehicle is currently under review by a GM technician, but they have delayed a response sense January 14, 2026. ----- Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes. The vehicle was inspected by a Chevrolet dealership and reviewed by a GM technician. It has not been inspected by police or insurance representatives. --- There were no dashboard warning lights. The primary symptom was loud, persistent squealing from the front and rear brakes and noticeable premature heat spots on all the roters. The noise developed within approximately one year of ownership and at relatively low mileage for a new vehicle.

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.

The contact's wife owns a 2024 Chevrolet Traverse. The contact stated that while his wife was driving 60 MPH, the brake pedal was depressed and went to the floorboard, and the vehicle failed to respond. The driver engaged the parking brake; however, the vehicle failed to respond. The driver swerved to avoid the vehicle in front, drove over an incline, jerked the steering wheel, and the vehicle eventually stopped. The message "Braking Module System Failure" was displayed. The contact stated that the incident was frightening for his wife and his two children, who were also inside the vehicle. The vehicle was towed to the dealer, where it was acknowledged that the braking system module and the parking brake had failed; however, no official diagnostic information was provided. The vehicle was repaired under warranty, and the contact was advised that the vehicle was drivable; however, the contact advised the dealer that there were safety concerns because the cause of the failure was not yet determined, and there was no guarantee that the failure would not recur. The vehicle was driven back to the residence, although the contact remained concerned. The manufacturer was notified of the failure, and a case was filed, but no further assistance was provided. The failure mileage was approximately 28,000.

I experienced complete brake failure while coming up to an intersection during rush hour. To avoid crashing into the vehicles in front of me I went off the road onto the shoulder and coasted until I stopped. During this “brake failure” popped up on my dash. (I have a picture) I ended up turning the car off and then starting it back up. Everything appeared to be fine, however I was not fine. I called the dealership right away and brought in. They diagnosed it as needing brake master cylinder and it took about 30 days for the vehicle to get fixed. Now I’m experiencing transmission fluid leaking. The vehicle shudders when accelerating.

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.

Dec 22, 2025

Purchased my vehicle brand new in October 2024 and around 3000 miles give or take the front brakes started to squeal. I reported the issue to the dealership on several occasions and was told this is normal due to dust, etc. I have owned 3 brand new vehicles in my lifetime and I have never had this issue with a brand new vehicle with 3000 miles or less on a vehicle; especially a vehicle purchased for almost $60,000. My vehicle currently has 17,000 miles and the squealing continues just as it was at 3,000 miles. My front brakes currently show 18% brake life left on the dash in the vehicle status. This is unheard of for a brand new vehicle to be needing brakes this soon. Which would explain the squealing brakes, they have placed cheap brakes, rotors, etc on this new model. If it weren't for this vehicle status feature showing the life remaining for each component, I could possibly unknowingly experience brake failure and would not have been aware that the brakes were at the end of life so soon; almost less than a year from purchase. This issue needs to be addressed with the manufacturer and looked into before someone driving a brand new vehicle, thinking they still have good brake life ends up killing themselves or someone else due to brake failure.

My 2024 Traverse was delivered with defective third-row seat headrests that do not return to their normal upright position after being folded, compromising passenger head and neck protection in a collision. On October 28, 2025, the vehicle developed a coolant leak confirmed by the dealer, but repairs have been delayed due to a national parts backorder, creating a risk of engine overheating or sudden breakdown while driving. Additionally, the front brakes began squeaking excessively about one year into my ownership, and the brake pad wear sensor shows only 18% life remaining at 18,454 miles, which raises concerns about reduced braking efficiency and increased stopping distance. All issues have been reported to an authorized dealer and remain unresolved except for the third-row headrests. These conditions pose significant safety risks to occupants and other road users.
