The contact owns a 2021 GMC Sierra 1500. The contact stated while using the GPS, the digital speedometer failed to operate as needed. The contact notified the dealer of the failure and the system was rebooted; however, the failure persisted. The manufacturer was made aware of the failure and a case was opened. The approximate failure mileage was 1,000.
While driving, when approaching speed of 40 mph, the engine begins to have dull shutter intermittently as though I am going over pot holes or rumble strips when I am not. Regardless of time or day or weather the truck has performed in this way. I have had it to the dealership twice for the issue. The first time they said they didn-??t feel anything and unable to duplicate the problem. The second time, the vehicle was with the dealer for several days trying to determine the other issue it was there for. I requested they again try to recreate the concern. The service assistance asked if I was willing to ride with the technician to see if I could point it out for him. In scheduled a time to do so, when I arrived, the technician was not there. I reside an hour away from the dealership. Making these round trips and getting no where with support or answers. When this happens, I become extremely anxious about the safety of the truck. Also- while 4 X4 is engaged, the truck has significant shutter when going up hill, as though the transmission is going to drop. The entire truck will violently shake.
The console radio dash has gone completely black while both driving and while using it for the speaker/phone system. The incident resulted in the entire system restarting.
Can turn vehicle off while in gear (drive specifically). When you let off the brake, the truck acts as if it is in neutral. Discovered in my driveway when accidentally forgot to shift into park when I pulled in and pushed the stop button. Truck turned off, which would only expect if in park (or neutral), let off brake, and it began quickly rolling backwards as if it was in neutral. Fortunately the brakes were working, but had any children been riding a bike on the sidewalk or walking by, my truck may have hit them. Had I been more distracted and not noticed initially, it could have rolled into the road and hit my neighbors truck. This behavior can be reproduced every single time, and I can easily supply video.
Less than 300 miles on the vehicle and it has thrown an error code P2B60. Relating to the engine coolant flow control valve position sensor. I have taken it to my local GM service center and they cannot see me for weeks. As of this morning the check engine light has disappeared but my fuel economy has severely decreased. It seems suspicious and possibly dangerous that it showed a check engine light with a warning of reduction in engine power the night before and disappeared in the

Started vehicle up in public parking lot and it had service power steering and ESC messages. Vehicle could not turn and had to be towed to dealership. The problem has been confirmed by the dealer but they have had the vehicle for 2 days and cannot fix the problem. Dealer states code keeps coming up in BCM but they are not sure why or how to confidently fix it. There were not warnings or any symptoms of this problem as it drove to work fine that same morning.
Prior to this incident I had lifter failure on my 2021GMC SierraAt 8464 miles, I was on my way to work and I heard a loud bang and I had to pullover off the highway, my dad had to come all the way out To get the vehicle because it had major engine damage and it was on a holiday so no one would come help me.The vehicle was in the shop for over a week getting these repairs done, upon receiving vehicle it had been a week and I received service four-wheel-drive messages on the dash.Trying to use four-wheel-drive after this was a no-go every time I push the button nothing would happen it would stay in two wheel drive.After this I made an appointment with the dealership for this issue to be fixed, as I was going to get readyTo leave again with the truck having no issues other than what I-??ve stated when I went to go start the truck nothing happened at all every light lit up on the dash and part of me thinks it-??s an electrical issue but the Other part of me thinks the motor is locked up. Also the lights would not shut off when I turn the vehicle off so I-??ll have a dead battery in the morning.
I started my truck this morning, drove it 3 miles, and all of a sudden got an ESC warning, Parking break warning, and a degraded power steering warning all at one time. My steering wheel started vibrating vigorously, a clanking sound started under the hood somewhere, and none of my safety features worked after.. Cruise Control, Vehicle Collision Control, Vehicle Gap sensors, etc.. The vehicle is currently at the dealer being looked at.
This is the second time I stop at the grocery store for about 15 or 20 min, get back in the car push the start, then the truck keep cranking with no start for about 20 seconds. Then I try second time and it fires up.
The auto stop feature on my truck is dangerous! there is no way to permanently disable it. When pulling into traffic from a stop, there is a significant delay for the car to restart and get moving! I have almost been in several accidents because of this. Forget the $20 in gas this junk might save someone over a year! it is dangerous
Returned home after some shopping. Parked truck in drive way. Approximately 5 minutes after returning home my wife saw truck smoking from under the hood. Within another minute or two there were visible flames coming from the back edge of the hood. We called 911. Within 5 minutes the entire front end of the truck was engulfed in flames. The fire department arrived and put out the fire but the entire front and cab of the truck was destroyed. Fire investigators determined fire started at back of engine compartment near battery. Vehicle was stopped parked in off condition. In my driveway. No mechanical problems were noticed on ride home and there were no panel alerts for problems.
