I received notice that there are two recalls out for my truck: a brake system recall and a forward camera/collision recall. Had both recalls performed and immediately the forward camera collision alert, lane keep and intellibeam systems didn't work. Delaer informed me there is a problem with the update and I need a new camera. That is on order and pending. More importantly, about 2 days after the updates the truck showed alerts about the brakes, traction control and stabilitrack systems. Upon driving the truck the power/vacuum assist system failed and the brake pedal nearly went to the floor before engaging brakes; I could barely stop. Returned the truck to the dealer and was told its a common issue with the brake recall update (the truck had no such symptoms before the update). If you check out various gm vehicle owner forums you will see scores of silverado and sierra owners with the same two issues post-update: no collision camera and sudden loss of brakes. There is a problem - a very dangerous problem - with these updates.

Tl* the contact owns a 2019 gmc sierra 1500. The contact stated that the back up camera was faulty. The features worked intermittently and would not complete all views of the rear of the vehicle. The screen turned blue and "service back up system" appeared on the camera screen. The contact stated that the vehicle also had a lane assist sensor; however, the seat would not alert the contact or vibrate when he drifted out of the lane. The vehicle was driven to home dale schwartz gmc (145 willow ave, honesdale, pa 18431, (570) 253-4222) where it was diagnosed that a new module needed to be installed in the rear seat. The contact did not know what side of the rear of the seat the module needed to be placed. The vehicle was not repaired. The mechanic ordered the new module and stated that it would arrive in three weeks. The manufacturer was made aware of the failure. The failure mileage was 1,800. The VIN was unknown.

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.

Vehicle screens including both the driver information area and the infotainment screen began flashing alerts/warning about disabled cross traffic alert, lane keeping assistance, and trailer connection/disconnection warnings. Alerts happened ever 2-4 seconds with screen flashes each time. Very distracting in the dark which makes it difficult to pay attention to the road. Almost rear ended another vehicle due to this issues.
