CHEVROLET SUBURBAN 1500 2025 ELECTRICAL SYSTEM
high2025 CHEVROLET SUBURBAN HIGH COUNTRY. Vehicle is parked in my garage. Went out in the AM and the engine only cranks, will not start. Called On Star for roadside assistance. Sent a tow truck, the vehicle could not be towed due to the electronic transmission. There is no way for an owner to place the transmission in neutral. Vehicle is stuck in my garage. GM customer service referred me back to roadside assistance who for the second time stated that they could not help me. This is a serious issue. The fact that the transmission can NOT be shifted into neutral unless the engine is running is a very serious safety concern.Called GM helpline a second time. They said that I should call for a tow on my own. Waiting for the selling dealer to call me back. Vehicle is currently stuck in my garage and GM does not care.
CHEVROLET SUBURBAN 1500 2025 VISIBILITY/WIPER
lowCar was parked (in covered area) when back window shattered sometime after 12pm. Car had not been driven in two days and outdoor temperature started at 62 that morning so there were not extreme temperature changes as at the time the window shattered, it was approximately 75 degrees. No apparent reason for breakage as we live in a secluded area and were nearby outside enjoying the day.
