2024 Chevrolet Traverse

The contact owns a 2024 Chevrolet Traverse. The contact stated while driving at various speeds, the check engine warning light illuminated on the instrument panel. The vehicle was taken to several dealers and the contact was informed that the issue was related to the OnStar feature. The contact called OnStar but was informed that the App was not responsible for the check engine warning light being illuminated. The vehicle was taken back to the dealer and a reset was performed of the check engine warning light. The contact stated that while driving at various speeds, the transmission unexpectedly downshifted without warning. In addition, the contact stated that upon turning off the vehicle, an abnormal, banging sound was coming from the engine. The vehicle was taken back to the dealer however, the cause of the failure was not yet determined; however, the contact was informed that the front drive axle was leaking. The front drive axle was replaced; however, the failures persisted. The manufacturer was notified of the failure but offered no assistance and the contact was provided a case number. The vehicle was not repaired. The failure mileage was approximately 500.

With only 1017 miles on vehicle, the transmission leaked all of the fluid out. Incident happened on a side street, thankfully not on the freeway as this would have been even more of a safety concern. Vehicle was sent to local dealership for inspection. NO warning lamps or messages appeared before, during or after the transmission fluid leaked out of the vehicle.

The manufacturer was contacted and opened a case, but no additional assistance was provided. The failure mileage was approximately 2,200.

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.
