The contact owns a 2020 GMC Sierra 2500. The contact stated that while driving 65 MPH, there was a burning odor coming from the vehicle. The contact depressed the brake pedal, however, the vehicle failed to respond as needed. The vehicle was pulled over to the side of the road, coasted into a ditch, and went into a field before coming to a stop. After the vehicle came to a stop, the contact became aware that there was a fire behind every wheel, and the flames had spread to the grass. The fire was self-extinguished. The contact referenced NHTSA Campaign Number: 21V758000 (Service Brakes, Hydraulic); as the possible cause of the failure; however, the VIN was not included in the recall. The contact stated that the failure had previously occurred in 2023. The vehicle was towed to a tow yard. The failure mileage was 201,000.
This morning it seems as if my 6.2L GM motor threw a rod. All the initial sounds and check engine information point toward that. I will be taking it to a dealer to confirm the issue. Data center driving ability and sounds indicate steering was affected as well or is somehow connected.

I own a 2020 GMC sierra AT4. It has developed a shudder when cruising on the highway or driving in town around 1500rpm. I believe it is coming from the transmission. A local shop mentioned the torque converter. The shudder feels like a delay in power and makes it difficult to hold speed or accelerate when needed.
