I have a 2018 Acadia with less than 18,000 miles. I just had an oil change a week ago and filled up my tank yesterday. Today I go to start my car and there are a ton of messages on my dash. Service theft deterrent system, service parking brake, service stabilitrak, program cluster, battery saver active, service battery charging system, fuel level low. The “park” light is on and the radio won’t come on. I had the hardest time locking the truck and the beep was low and the inside lights were flashing and the windshield wiper blades were slowly moving. I’m going to have it towed tomorrow since it’s Sunday today and everything is closed. Any idea what may be wrong? I’m really worried.
