When I tried to drive my truck I received the below error messages and lights on my dash board: steering assist reduced drive with care service trailer brake service esc brake system failure - 62 mph top speed abs check engine brake traction control I dropped the truck off at the GMC dealer for two days, I picked it up and it was fine. I was told it was a software update. Then 7 days later I had the same errors messages and lights on my dash board. And this time it was extremely hard to stop the truck. I needed to press down all the way to stop the truck.
When I am driving my truck, I will get notifications saying that there is a trailer disconnection issue when I don't even have a trailer connected. It also flashes an alert saying that the lane departure system and pedestrian sensor are being effected. As this is going on, the infotainment screen flashes on and off as well which is very distracting. They have continued to come on in cold weather after I have taken it to the dealership to be looked at. I don't know if this is a hardware or software problem but it needs to be addressed because it becomes both a large nuisance and safety hazards when you have errors messages and lights flashing while you're driving.
