The left or right-side roof-rail air bag (RRAB) inflator end cap may detach from the inflator or the inflator sidewall may rupture.

Risk: A detached end cap or inflator rupture can allow compressed gas to escape and project the end cap or fragments of the inflator into the vehicle, increases the risk of injury or crash.

ENGINE AND ENGINE COOLING:ENGINE:HARD PARTS INTERNAL/MECHANICAL

The connecting rod and/or crankshaft engine components may have manufacturing defects that can lead to engine damage and engine failure.

Risk: Engine failure increases the risk of a crash.

STRUCTURE:BODY:BUMPERS:ACTIVE SHUTTERS/GRILL

General Motors, LLC (GM) is recalling certain 2022 GMC Sierra 1500 vehicles equipped with chrome front grille deflectors. The attachments that hold the front grille deflectors in place may fracture, resulting in grille detachment.

The left or right-side roof-rail air bag (RRAB) inflator end cap may detach from the inflator or the inflator sidewall may rupture.

Risk: A separated inflator end cap or inflator rupture can allow compressed gas to escape, resulting in the end cap or other components being propelled into the vehicle, increasing the risk of injury or crash.

POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE:SOFTWARE

General Motors, LLC (GM) is recalling certain 2020-2022 Chevrolet Silverado 1500, 2500, 3500, GMC Sierra 1500, 2500, 3500, 2021 Cadillac Escalade, Escalade ESV, Chevrolet Tahoe, Suburban, GMC Yukon, and Yukon XL vehicles equipped with diesel engines.

Risk: Rear wheel lock-up can increase the risk of a crash.

SERVICE BRAKES, HYDRAULIC:BRAKE FLUID LOW WARNING: LAMP

General Motors, LLC (GM) is recalling certain 2023 Chevrolet Silverado 1500, GMC Sierra 1500, 2023-2024 Chevrolet Tahoe, Suburban, GMC Yukon, Yukon XL, Cadillac Escalade, and Escalade ESV vehicles. The electronic brake control module software may fail to display a warning light when a loss of brake fluid occurs. As such, these vehicles fail to comply with the requirements of Federal Vehicle Safety Standard number 135, "Light Vehicle Brake Systems."

Risk: Without a warning light, the vehicle may be driven with low brake fluid, which can reduce braking performance and increase the risk of a crash.

EXTERIOR LIGHTING:LIGHTING CONTROL MODULE:SOFTWARE

General Motors, LLC (GM) is recalling certain 2020-2023 Cadillac CT4 and CT5; 2021-2023 Buick Envision; and 2022-2023 Cadillac Escalade and Escalade ESV, Chevrolet Silverado 1500, Suburban, Tahoe, GMC Sierra 1500, Yukon, and Yukon XL vehicles. The daytime running lights (DRLs) may not deactivate when the headlights are on. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."

Risk: DRLs that do not deactivate as intended may result in a glare, reducing visibility, and increasing the risk of a crash.

AIR BAGS:FRONTAL:PASSENGER SIDE:INFLATOR MODULE

General Motors, LLC (GM) is recalling certain 2012 Cadillac Escalade, Escalade ESV, Escalade EXT, Chevrolet Avalanche, Silverado 1500, Silverado 2500/3500, Suburban, Tahoe, GMC Sierra 1500, Sierra 2500/3500, Yukon, and Yukon XL originally sold, or ever registered, in the states of Alabama, California, Florida, Georgia, Hawaii, Louisiana, Mississippi, South Carolina, Texas, Puerto Rico, American Samoa, Guam, the Northern Mariana Islands (Saipan), and the U.S. Virgin Islands or "Zone A." These vehicles are equipped with non-desiccated passenger frontal inflators containing phase-stabilized ammonium nitrate (PSAN) propellant. These inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, high temperatures, and high temperature cycling.

Risk: An inflator explosion may result in sharp metal fragments striking the driver or other occupants, resulting in serious injury or death.

TIRES

General Motors LLC (GM) is recalling certain 2020 Buick Enclave, Cadillac XT4, XT5, Escalade, Escalade ESV, Chevrolet Suburban, Tahoe, Traverse, GMC Yukon, Yukon XL, 2018-2021 Chevrolet Express, GMC Savana, 2019-2020 Chevrolet Blazer, Silverado 1500, GMC Acadia, Sierra 1500, and certain Continental tires sold to the aftermarket for various model year 2018-2021 vehicles. The affected tires were cured for too long during production.

Risk: Over cured tires may develop a break in the sidewall resulting in sudden air loss or a belt edge separation which could lead to a tread/belt loss. Either condition can cause a loss of vehicle control, increasing the risk of a crash.

STEERING

My power steering completely failed. This is a safety issue and could have caused bodily harm. I have looked on line and I am not the only one with this issue, and as I investigated it shows that this issue was recall situation on earlier models. My truck is currently in the shop and looks like it will cost $5,000 to do the full repair.

STRUCTURE:BODY

The upper part of the grill detached on my 2023 GMC Sierra 1500 while going 65mph on the higway. The part is about 4 inches wide by 6 ft long. People behind me in traffic were swerving and dodging to avoid hitting it. GM knows about this problem (see safety recall #N242490120), but the scope of the affected vehicles is incorrect, so my truck is not included. There were no signs that the part was going to fail before hand.

UNKNOWN OR OTHER

I am experiencing a recurring issue with my 2021 GMC Sierra where the dashboard displays a “Shift to Park” warning even though the vehicle is already in Park. This typically occurs when I attempt to shut off the vehicle. The doors unlock as expected, confirming the truck is in Park, but the warning prevents me from turning off the ignition immediately. After a few seconds, the warning usually disappears, allowing me to shut off the truck. This issue is more frequent in cold weather, suggesting a temperature-sensitive electrical or mechanical fault. Based on research and community reports, this appears to be a known issue across multiple GM vehicles, often linked to a faulty micro switch or wiring harness in the shifter assembly. I am concerned about the safety implications, especially if the vehicle fails to shut off properly or if the issue worsens over time. GM has not issued a recall for this problem, and I believe it warrants further investigation due to its widespread nature and potential risk.

STRUCTURE:BODY

After completion of a recall fix by the dealer for the grill while driving the front grill deflector detached striking the front hood and top of the cab before flying behind my vehicle barely missing a following vehicle and settling alongside the road. I pulled over, inspected the front of my vehicle to assure it was safely drivable. Once I removed loose pieces I returned and retrieved the top grill from the roadside then drove directly to the dealer who completed the recall fix. They have ordered a full grill for replacement. The recall fix/repair failed within day of completion. GM Program # N242490120 Status Complete NHTSA 25V060 Date Issued: 2025-02-06 Description General Motors has decided that a defect which relates to motor vehicle safety may exist in certain 2022 model year GMC Sierra 1500 vehicles equipped with chrome front grille deflectors. One or more of the attachments that hold the front upper grille deflector in place may fracture over time. If all eight attachment points break, the deflector may detach from the vehicle while driving. Safety Risk Description If a front grille deflector detaches unexpectedly while driving, there is increased risk of a crash. Repair Description Dealers will reinforce or repair all attachment points on the chrome front grille deflector. Recall Completed 2025-08-21

UNKNOWN OR OTHER
