2024 Chevrolet Traverse

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

Back in December 2025 took car in because there was a coolant leak until the car started. Alerting me that it was overheating in the middle of the freeway. I had to find a place to pull over while the car was alerting. With urgent urgent urgent alert to pull over. Took it into dealership and it Turns out it had a coolant hose leak . I took the car in for an oil change TODAY and turns out has a host leak again. The dealer did the inspection and I don’t have the part available to fix it. And this is a brand new car giving me issues. I travel far on weekend so this would be hazzard. The dealer said the water tank low because of the leak. It’s also the rear backseat window would not go Thank you It’s leaking, and that’s a safety issue. Because if there’s Down emergency, we can roll the window down. We also had an issue with the break pad alert system alert me. There was no brakes. It turned out to be in update issue and again I was going to travel on vacations. Those are other issues. I’ve had with the car but the maintenance issue today is at the clothes again is leaking and is a safety hazard because if I’m driving and the car and it overheats.

On the car seat there are two indicators to tell you if the seat is locked in place because it is a rotating car seat. Both indicators never fully go in the “green” meaning the seat is fully locked into place. The car seat is less than two years old and both indicators are malfunctioning, they aren’t going fully in the green. I reached out to the company with pictures and videos and they have done nothing to help. They said from the video it looks like the car seat is functioning properly and they will not fix or replace it.

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.

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.

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.

This was one of about ten times this has randomly happened when using Super Cruise. We were heading south on I-41 and super cruise is active and set around 80 mph, I entered an area where Super Cruise became unavailable or the system indicates that road information is not available, the vehicle immediately began to rapidly decelerate to under 60 mph within 5 seconds of the vehicle notifying me with red bar on steering wheel and one buzz of my seat. Causing serious concern for safety of my family in the vehicle. During this deceleration, I am unable to override or stop it — pressing the brake pedal does not cancel the slowdown, applying the accelerator has no effect, and no control buttons will disengage Super Cruise. All pedals are dead. All buttons to cancel do not disengage what the CAR is doing. The vehicle continues to slow down on its own, which poses a significant safety risk on highways and interstates.

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 filing this complaint regarding a persistent and unresolved defect with my 2024 Chevrolet Traverse, VIN: [XXX] . The first occurrence of this issue was in June 2025. Since then, the vehicle has repeatedly experienced a “Check Engine” warning, engine misfires (cylinder misfire), loss of power while driving, and severe engine shaking. These symptoms make the vehicle unsafe to operate. The vehicle has been taken to an authorized Chevrolet dealership approximately 20 times for the same ongoing issue. Despite multiple repair attempts, the problem has never been permanently resolved. In total, the vehicle has spent about three months out of service at the dealership. As of January 14, 2026, after the vehicle has been at the dealership for over two weeks, I was informed that the dealer is unable to repair the vehicle. They have escalated the case to the manufacturer, General Motors, because they cannot identify a permanent solution. The current mileage of the vehicle is approximately 41,700 miles. This ongoing defect makes the vehicle unreliable and unsafe for normal use. The repeated failures to repair suggest a potential manufacturing or design defect rather than an isolated incident. I respectfully request that the National Highway Traffic Safety Administration review this matter and determine whether an investigation or further action is warranted.

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.

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.

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.

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.

Completely disgusted with Chevy traverse. Upper radiator hose busted and radiator leaks at seem, squeaky brakes since day one purchased then sensor on brakes went bad causing it to say brakes are less than they actually are says 18% and it’s actually 88% caused the engine light to come on ppl can’t afford a payment and be at the dealer all the time and without transportation. It’s my only vehicle and I need it fixed but everyone says part is back ordered or something this is a shitty vehicle Chevy needs to pay to replace brakes sensor hoses and radiators even if it’s past factory warranty these vehicles cost to much not to last past 36,000. Ridiculous there needs to be a recall this is becoming a very well known problem Chevy should have to cover to fix it and make it right and provide a vehicle while it’s in the shop. Very upset with Chevy and it’s quality and this needs to be recalled asap

At around 22,000 miles my vehicle went into reduced power mode with no indication of why. This happened while I was going up a steep hill and the reduction of power slowed my vehicle dramatically, and I was nearly rear ended. The vehicle had no check engine light on until the next morning. I got the check engine light read at Autozone and they indicated that it was for a coolant pump. When i checked the coolant reservoir, it was empty. I added GM approved coolant and the check engine light turned off, but I had already set up for the vehicle to be serviced at Earnhardt GMC, so I still took it in on 9/19/25. They had my vehicle there for 5 days and said it was a valve that was causing a leak, and they had replaced it. On 10/12/25, my vehicle went into reduced power mode on the freeway again. I still had no check engine light. I had to wait until the morning to take it into the dealership again. In the morning the check engine light came on again, so the dealership was able to read it and it was the same code as before. This time they only needed the vehicle over night, and said the coolant leak was from a bad water pump. on October 27th, my vehicle once again went into reduced power mode on the freeway, and again no check engine light. The next morning the check engine light was present and I again took my vehicle to Earnhardt GMC to have it diagnosed. Once again it had the same code. The next day I received a text message from my service advisor, that the issue was from the radiator hose and that they will be ordering it. So at this point I am in a rental car that was covered by my warranty. I asked if they had any updates 2 days later, and was told they didn't. On 11/3/25, while looking at a Facebook group for 2024 Traverse owners, I saw a number of people with the same issue I was having and getting month long ETAs for repair. It was later confirmed that my part will not be available until between 12/16/25-12/30/25. My vehicle is currently still at the dealership.
