Trailblazer

There is something wrong with the battery charging system, this is a known issue for GM. I've brought it to the dealership to address the issue and they do not know what is wrong or how to fix it. Sixteen times since I got this vehicle it has flashed a warning "service charging system: your vehicle may stall because the battery is not charging properly. Schedule service soon." I obtained this vehicle April 30th with 5 miles on it. They still do not have a fix for this, the dealership stated they would contact me when there is a recall....

On 4/14 with only 21 miles on the odometer in this newly purchased car the entire transmission failed, per the dealership because of a “leaking valve”. The check engine light came on after the car was jumpy and then the car refused to speed up on an extremely busy street and began locking up, putting us at serious risk of an accident. It was barely able to reach a parking lot and at that point all of the transmission fluid leaked out all over the parking lot.

While driving the car stalled and eventually stopped running. The battery was still on, but there was no power to the engine. The car needed to be pushed out of the road and towed to the dealership for work.

See attached document for complaint.

The contact owns a 2025 Chevrolet Trailblazer. The contact stated that when he stopped the vehicle and had shut the vehicle off but had left the vehicle in drive (D) and had not engaged the parking brake, the vehicle rolled forward. The contact stated that this was also occurring when he had stopped the vehicle, turned the vehicle off and placed it in reverse (R) without engaging the parking brake the vehicle rolled backwards. The contact had not taken the vehicle to a local dealer or independent mechanic. The vehicle was not diagnosed and was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 700.

Vehicle would not go over 20 mph at times. When vehicle would shift from 2nd to 3rd gear the engine would race yet not engage.

My Navigation, Radio, Internet and OnStar went out and continually goes out on a day-by-day basis. I was in a different state, and it was pouring rain, my navigation, radio and OnStar ability was gone. Chevy knows this is an ongoing issue with 2024 and said the radio is back ordered. This car is a 2025 and its still and issue. The ability to fix it has been stated as unknown because they have no fix for the radio at this time in either year. When you rely on Navigation to get you home and it leaves in torrential rainstorm, and you have no idea how to get home that is bad. If I had been in an accident or God forbid rolled down a hill. OnStar would not have been alerted to this and it could be a potential life or death issue. Everything in the front of the car goes out. I am not sure what else is affected as the car is new and I am learning all the different devices. In all states nationwide it is illegal to hold your device, that is why we rely on this technology. There is no lights or failure indication other than the OnStar goes red and the radio goes out. OnStar has stated if my button is red, it's a hardware failure and they will not be alerted, and I will not be able to alert them to an emergency situation.
