General Motors, LLC (GM) is recalling certain 2024-2025 Chevrolet Silverado 2500 and GMC Sierra 2500 vehicles equipped with the enhanced towing option and 20-inch accessory tire/wheel package. The tire information label may state the incorrect rear tire pressure, resulting in underinflated tires and preventing the tire pressure monitoring system (TPMS) from displaying a low tire pressure warning.
General Motors, LLC (GM) is recalling certain 2024 Chevrolet Silverado HD 2500, 3500, and GMC Sierra HD 2500, 3500 vehicles equipped with power-unlatching tailgates. The tailgate's electronic gate-release switch may short circuit due to water intrusion, which can result in the tailgate inadvertently unlatching while the vehicle is in Park.

The tailgate's electronic gate-release switch may short circuit due to water intrusion, which can result in the tailgate inadvertently unlatching while the vehicle is in park.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“The vehicle experienced a loss of engine power accompanied by a check engine warning light and a “Reduced Acceleration”/reduced-power condition. The exact component causing the malfunction has not yet been determined. The vehicle and any affected components are available for inspection upon request. While driving the truck uphill toward our residence, the vehicle lost significant power and had difficulty maintaining acceleration. The truck stalled several times. The sudden loss of engine power while driving on an incline created a safety risk because the vehicle was unable to maintain normal acceleration and could potentially have stopped in traffic or created a hazard for other vehicles. The problem has not yet been confirmed or reproduced by a dealer or independent service center. The vehicle has experienced the problem while being driven, including the reduced-acceleration condition and multiple stalls. The vehicle will be inspected by a GMC dealer on Monday, September 28, 2026. The check-engine warning light illuminated, and the vehicle displayed a reduced-acceleration/reduced-power condition. The truck subsequently experienced significant loss of power…”
“driving down the road going to and intersection the dash says I received a Service ESC message followed by a Reduced Acceleration warning on the center display. I also had the forward collision, traction control and check engine lights come on. I also noticed the shudder/jerk. The truck is giving a P060C code and when i was driving it dies in the intersection of the road and will not start back up. puts the computer in a safety mode. I have call my local GM dealer and they did not fix it and it happen twice. I the truck dies in the middle of the road and no way to start's it and if a big rig crashes in to the truck some one or more than one will be hurt or killed”
“Intermittent trailer disconnect and loss of electric trailer brake output while towing Airstream. The truck is connected to the trailer through the seven Way plug. There are no modifications to the truck. This is a safety hazard as I pull a 9000+ lb trailer. Trailer connection drops momentarily and integrated trailer brake controller loses communication with trailer brakes. I went on a 5000 mile trip and my trailer brakes were connecting in disconnecting consistently. Every time there was a disconnection or connection the vehicle would “ding ding. This virtually happened consistently while we were on this long trip. During the trip, we tried to wedge the plug tight and zip tie the door shut, attempting to keep the plug tight. My truck is at the dealership, waiting on a “tool“. This is the second time it has been in the shop for this issue. I supplied a picture of the dash message after it got tired of connecting and disconnecting. I feel this is a serious safety issue. Thank you, [XXX]”
