ID: 2124114FORWARD COLLISION AVOIDANCE: WARNINGS
My Onstar system is not working properly. I first noticed the Forward Collision light then the Wifi hotspot features not working. Reached out to onstar they couldn’t help then referred to dealership. Visited dealership 8/12/2025 was told there’s no error code although they see what’s happening. Doing further investigation of my own i found out this is a very well known issue amongst General Motors, Onstar and the dealerships selling these vehicles. There are varying issues customers are having from wifi not working to vehicles completely shutting down in traffic. Once my visit to the dealership commenced i was informed the Telematic Control Module” is on back order with no estimate on deliveries as there’s “others waiting also” this is a scary situation. I am worried that my issue is going to progress into a bigger problem. I drive 23 miles to work and 23 back. I am scared that my module will eventually fail when i am on the highway…..this is terrifying! Over 80k to play roulette.

The engine in 2025 Suburban (6.2L V8) has failed and the car is not drivable. It is currently in a Chevy dealership service department waiting for parts. The 2025 model is not listed under the recall. However it should be, I know of 3 2025 engines that have recently failed. I was passing a vehicle and as I took my foot off the accelerator the transmission shifted 2 times and then the engine shut off and the car was coasting. We had no indication that the engine shut off, just several messages on the screen. ( Press start button, and conditions not correct for shifting.)

New vehicle purchase, the Dealer had installed a 3rd brake light that blinks 4 to 5 times when pressed. I'm concerned because according to what I've read a blinking brake light is against federal and state regulations.
