2024 Chevrolet Traverse

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.

Emergency brake engaged while driving in reverse causing the vehicle to abruptly stop 3 times leaving the driveway. This continues to occur as we left the house moving forward decelerating the vehicle. My [XXX] infants were in the vehicle causing them to scream, and this defect could have easily caused a crash. I no longer feel safe driving the suv. We proceed to call the dealership we purchased it from (Rick Hendricks Chevrolet of Naples) Spoke with management the guys name was Jack. He said this is an ongoing issues they are working on and told us to bring it in. I’m not driving this vehicle on the highway an hour away so we are now escalating the situation to headquarters.

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.

The contact owns a 2024 Chevrolet Traverse. The contact stated while driving 45 MPH and depressing the brake pedal, the message "Brake Assist Failure" was displayed. The contact was able to pull over to the side of the road. The contact stated upon turning off and restarting the vehicle, the message was no longer displayed, and the vehicle operated as needed. The contact stated while driving 25-30 MPH at the airport, the failure recurred. The contact stated that upon turning off and restarting the vehicle several times, the failure persisted. The messages "Brake Assist Failure" and "Forward Collision Not Available" were displayed, and the check engine warning light was illuminated. The contact was able to drive 5 MPH and pulled over to a safe location. The vehicle was towed to the residence. The vehicle was then towed to the dealer, where it was diagnosed that the brake master cylinder had failed and needed to be replaced. The dealer was awaiting the parts to repair the vehicle. The vehicle was not repaired. The manufacturer was notified of the failure and a case was opened. The failure mileage was approximately 1,900.

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.

The contact owns a 2024 Chevrolet Traverse. The contact stated while driving approximately 15 MPH, the brake pedal was depressed, and the vehicle jolted forward with two unknown warning lights illuminated. The contact stated that the Forward Collision Avoidance and 4WD Unavailable messages were displayed. The vehicle was towed to a dealer to be diagnosed. The contact was informed that the "Rear Driver Side Sensor" needed to be replaced. The contact stated that two different parts for the rear sensor were replaced; however, the failure persisted. The manufacturer was notified of the failure. The failure mileage was 2,631.

on multiple occasions now this vehicle has applied automatic braking for no apparant reason. the vehicle has applied an extreme braking scenario. And applied the full brakes causing the vehicle to skid and extremely jar the interior passengers. this automatic braking was almost like driving the vehicle into a wall as it was immediately stopped. in the latest instance the vehicle behind me was barely able to avoid running into the rear of my vehicle.

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.
