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.

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.

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.

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 ;(

On July 31st, while backing up on a clear road in rain the brakes locked suddenly. The brakes applied & a message saying Emergency Parking brake engaged. Must be manually released. This happened twice in a 30 second period before there was enough room for me to pull forward out of the spot. I called the dealership on August 1st to see if this was a known issue and they said no. Brought the car in on August 2nd. They scanned for errors & found a message Lost Communication with Parking Assist Control Module with 9 other error message. They said this was not a known problem and to them it appeared to fix itself but would let me know if there was any way to fix. Car has just been in for regular multi point inspection on July 24th. On August 20th went to get in the car but none of the key fobs would open it. Called two dealerships but neither could come up with answer. Chevy Roadside was called & came to get into the car and ended up jumping it. At that time the battery was tested and it appeared fine. It was recommended to run it for a half hour. I ended up driving it for an hour with no extras on. On August 25th the next day I went to drive it the battery of this 1 year old car was dead. Called the two dealerships to see what could be done & was told to bring it in. Called Chevy Roadside Assistance who dispatched someone to open the car and jump the battery. This person found the battery was not holding a charge & said nothing when I said I was driving it to the dealership. Got 3 houses away & a message that the Brakes have failed. Press hard to brake popped up. In addition the steering locked up. I missed hitting a lady with a kid in a stroller by 6 ft but managed to get it to the curve & with 3 pushes into park. It was towed to the dealership. When it arrived at the dealership the brakes locked up so it would not back up off the flatbed. It had to be forced off. Dealer blames poor battery but can't explain July 31st or why battery readouts say okay.

We have experienced phantom AEB warnings and braking (60+ warnings w/o braking, around 10 brake activations) since owning the vehicle a little over a year now, purchased new. We took it into the dealer in May to have it addressed and they determined the AEB system was inoperable due to a defective front camera (windshield). After replacement and reprogramming, we picked up the vehicle and noticed a decreased sensitivity to our rear/side alerts AND ZERO forward AEB or proximity alerts of any kind. Not car, pedestrian, object or wall. Forward AEB alerts were completely disabled. Additionally, the vibrating safety seat which was previously inoperable (we assumed our car didn't have it) was on and functioning for all side/some rear alerts. We took the car back into the dealer and after 5+ days they determined it was a "faulty batch of cameras" and they replaced the front facing camera again. Today, we picked up the vehicle, being told everything was tested and reset so functioning properly- with our 3rd new forward camera. Yet, the AEB system was clearly inoperable again, zero front facing AEB/collision/proximity alerts - even though all settings 'on.' Rear alerts still seemed delayed and less accurate than before we brought the vehicle in the first time. I returned the vehicle to dealer and demonstrated again. My service rep agreed - it does not seem like it's just the front facing camera and must be a larger issue electronic issue. To date, I've been in contact with GM corporate executive team and have very little real concern or amelioration of these QC issues with the vehicle. We have spent over 20 days in the shop within 12mo. They refuse to acknowledge that there significant defect with the vehicle to warrant repurchase. These safety issues are only part of what appears to be serious QC deficiencies that put my family at risk. My wife and kids are in this car 98% of the time. I have video documentation from both camera repairs if you want to see them.

While backing out of a driveway into an unobstructed road with no oncoming traffic from either side nor any pedestrians or cyclists approaching, the automatic emergency braking system applied the brakes and then locked up leaving the vehicle as an obstruction in the road. To disengage the locked brakes required a large amount of pressure on the accelerator pedal bringing the engine RPMs up to a sufficient speed to disengage the automatic emergency braking system. Had there been traffic approaching what would have been an otherwise safe amount of time to bring the vehicle into the flow of traffic would have been insufficient and may have caused an accident. There was no warning indicating any of the vehicle sensors detected an approaching object or obstruction. This is the second incidence of the occurring in the last week.

I am writing to report a serious safety concern with my newly purchased. I believe this issue, if unaddressed, could lead to accidents. Specifically, when I am stopped at a stop sign with another vehicle behind me and the light changes to green, I begin to drive forward. However, as the vehicle behind me starts moving toward me, my car suddenly and violently applies the brakes. The force is so strong that it feels as if I've been rear-ended. This abrupt braking creates a dangerous situation as it increases the likelihood of me being rear-ended by the car behind me. It is important to note that I am in "Drive" mode and moving forward, not in reverse, so I would not expect the car to brake under these circumstances. This issue is not isolated, and I have experienced similar sudden braking on several occasions, but this scenario is the most concerning due to the potential for accidents. I took the car to the dealership, assuming it might be a programming error. However, the dealership informed me that this is a known issue with this model, but no recall has been issued to address it. I strongly urge the NTSB to investigate this matter further, as I believe it poses a significant safety risk to drivers and passengers. Thank you for your attention to this issue.

This vehicle was advertised as having the Super Cruise feature along with "following distance indicator", "forward collision alert", "lane keep assist with lane departure warning" and "intellibeam" (auto headlamp dimming feature). We purchased the vehicle expecting all of these to function. When we took delivery and went on our drive with the salesman so he could explain all the features, we found that the Adaptive Cruise Control and the Super Cruise would not work at all. We thought maybe we were trying to engage it incorrectly, so the salesman advised he would check into it the next day (we took delivery after regular service hours) and get back to us. We took the vehicle home. Upon driving the next several days, the Forward Collision Alert malfunction indicator light came on in the driver information center. We had made an appointment and took the vehicle to the dealer. We were advised that bulletin #PIT6167A was issued by GM on 6/20/2024 stating "Super Cruise Unavailable" and it was a known problem and at the time there was no fix. We were advised by the Dealer that the issue was a software engineering issue that GM does not have a solution for repair. GM allowed this vehicle to be sold knowing that the Automatic Driver Assist (ADAS) safety systems on this vehicle would not function at all. We knew the Adaptive Cruise Control and the Super Cruise systems would not work, but we found out on the road in the dark that the "Intellibeam" system was not working when oncoming traffic started flashing their bright lights. This was a safety concern. This was very irresponsible of GM to sell these vehicles with ADAS issues. How did this vehicle pass the quality control process at the factory? Research shows there are other models affected. Today I learned that there is a newer version of the GM service bulletin (new number is PIT6167C) that states there is still no repair process for the Super Cruise (and other affected ADAS systems) available yet. GM refused to buyback.

Transmission issue: Dealer was not able to replicate issue due to it only happening periodically. When putting into drive mode and going to accelerate it feels as if the transmission is slipping and give a big jerk. Also will sometime make a loud noise like tranmission is "dropping". Or when foots off gas peddle after going at a steady speed then go to accelerate again it will jerk. Dealership said that is normal as there is a "learning phase" which I've owned several new vehicles n never experienced this before. No warning lights have been shown. Reverse automatic breaking issue: Several occasions while reversing vehicle will slam into park mode when nothing is behind me. Brought to dealer, dealer said to shut off the notification. However, I don't want to have to shut it off. Tech did experience this once while attempting to reverse vehicle. But service advisor said there is no fix for this issue.
