Dear NHTSA, I recently leased a 2019 GMC Sierra pickup truck. This truck is currently in the shop for the 6th time, and neither GM or the local dealership can seem to fix anything on this truck. Most recently, as yesterday I had my car in for the braking system. The dealership called me and said my truck was fixed. As I turned my truck on, the brake system light came on. I was told by the dealership to just drive it and it will go away. I do not feel this is a good/safe practice and GM is not helping me to get out of this unsafe truck.

Cruise control would not disengage when the brake was applied I was on a highway traveling 65 mph. Had to take an exit ramp to avoid a collision with vehicle in front of and beside me.

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.

I have a 2019 GMC Sierra I took it in for recall services and took a road trip to Texas once I reached tax that evening I had a brake system failure going down the highway took it into the shop and had everything looked at and check they said truck was fine and the next morning on the trip back brak system failed again and both time check engine light was on for electric problem as well. Go the truck to the dealer again where it is currently at now. They will do the same thing and tell me the truck is fine or replace parts that was not the issue. I refuse to place my family life in danger by continuing to drive this truck it is a major safety hazard

First week of ownership I noticed that the rear window had a water leak by rear driver seat. While inspecting the leak, I notice that the paint on the rear brake spoiler above the rear window had two black marks. Body shop technician rubbed his fingers on the spots and paint was rubbing off. I started to receive 'service steering column lock' messages intermittently and regularly during startup. Heating indicator lights for all the seats do not light up to indicate their settings. This occurs while vehicle is stationary or on the road. The rear backup camera screen turns blue and displays 'service rear backup camera' while reversing and it occurs occasionally.

I am a heavy highway construction inspector for wvdoh and while working on I 81 sb in martinsburg, wv this morning around 2:00 am while performing my duties I attempted to pull out of my lane closure into traffic when my truck literally got stuck halfway out into live traffic. It was as if I was stomping on the brakes instead of giving it gas. Fortunately I reacted swiftly and put the truck in reverse to back into my lane closure preventing a collision with a tractor trailer traveling at speeds in excess of 55 mph. I was literally shaking when I realized how close of a call it actually was and that not only could I or the truck driver have been killed, but so could the workers on my job have been injured and/or killed. I had to have my truck towed back to my field office. For some reason the truck started driving properly again. There is definitely something wrong and it is extremely fortunate that no injuries occurred on my project. I did notice a post on this website explaining the very thing that happened to me this morning. This issue must be addressed immediately before people are killed.

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.

Trailer disconnect warning when no trailer is connected cold weather seems to cause the error the warning continually pops

- Buffalo, NY, USA

When the temperature drops below about 20 degrees (Fahrenheit) the center instrument cluster starts displaying emergency codes that require constant clearing, only to have the error codes reappear. The same thing happens on the infotainment head unit in the center stack -- it flashes, resets, cuts the sound in and out and displays trailering checklists. All of this is immensely distracting to the driver and creates a safety hazard. I've had it serviced and have been told GM engineers are aware of the issue (its common on 2019 Sierra and Silverado 1500 trucks) but have been unable to find a solution. I have video of both types of errors.

- Park Ridge, IL, USA

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.

Have about 6000 miles on my 2019 GMC seirra denali 5.3. I've been experiencing a very troubling issue been to the dealership once already and had a hard time convincing them that something was wrong with the truck.every time I drive for long periods of time or idle for 10+ mins when I shift from park to drive I cannot go faster than 5 mph without the rear brakes locking up. I do not know if this is some kind of limp mode or what.
