My GMC sierra with 40000 miles the check engine light turn on and was steady on when driving on the highway I loose a power on the vehicle for a few seconds and almost a semi truck behind me hit me because I don’t have any power on the vehicle, I stop on a safe place and try to start the vehicle again immediately call dealer for appointment an start drive to home. The lady on general motors say I can drive safe with my vehicle but I don’t feel safe because nothing on the onstar computer works the emergency button and gps it’s not working at all.
10/01/vehicle brought to dealership for the 6. 2l engine loss of propulsion recall. Engine passed the pico vibration test. Oil was changed from 0w-20 to 0w-40. Mileage was 29k. 06/17/engine seized at 43k miles. Was travelling 50 mph up a mtn pass. Barely had enough momentum to roll to the right shoulder out of traffic. 07/07/new motor installed. Back to 0w/20 oil. Since ownership, I have to on a regular basis reset the collison warning from seat vibration to beeps. It appears to reset back from beeps to seat vibration every time there is an over the air software update. It might even just randomly reset. I cant tell for sure. I recently had a small backing accident were I was expecting the beeps to alert me. I mentioned this to my auto insurance company. They told me this was not the first time they have heard of this type of situation.
