Issue: Over time, the transmission control valve could wear and lose pressure. If this happens, the transmission could shift harshly and could cause the rear wheels to lock up. Note: This recall only affects vehicles equipped with a diesel engine. Safety Risk: Rear wheels that lock suddenly could cause a loss of control and increase the risk of a crash. Corrective Actions: General Motors will notify owners by mail and advise you to take your vehicle to a dealership to update the transmission control module software to detect excess wear in advance of a wheel lock up. If detected, a service engine light would turn on, a message would display in the instrument panel and the vehicle would be limited to fifth gear.

2021 GMC Sierra Hd recall questions
Transport Canada lists 4 recalls for the 2021 GMC Sierra Hd model year. That counts campaigns naming this model year, not recalls on your vehicle: many cover only a VIN range or production window, and some only vehicles found on inspection.
Enter your VIN in GMC's Canadian recall lookup, or call a GMC dealer with your VIN. In Canada the manufacturer is responsible for showing recall and repair status for each VIN, so its lookup is the authoritative answer. Cardog uses your VIN only to find the model year; the recalls shown here are listed for that model year and are not matched to your VIN.
Not necessarily. NHTSA campaigns cover vehicles sold in the United States, and NHTSA's VIN lookup has no Canadian data. When a defect also affects Canadian vehicles, the manufacturer files a separate notice with Transport Canada, often under a different number and sometimes covering a different set of vehicles. For a Canadian vehicle, go by the Transport Canada listing and GMC's Canadian lookup.
Safety recall repairs are normally done at no charge by an authorized GMC dealer. The manufacturer's notice for each campaign sets out the remedy and any conditions, so confirm with the dealer when you book.
Once GMC's lookup or a dealer confirms a recall applies, book the repair with an authorized GMC dealer and bring your VIN. If the manufacturer's notice says not to drive the vehicle or to park it outside, follow that instruction. Parts can take time, so book early.
Follow the manufacturer's notice for that recall. Most allow normal driving until the repair; some tell owners to stop driving or to park outside until it is fixed. Cardog does not grade recalls by severity: the manufacturer's notice and your dealer are the source.
Manufacturers must notify owners they have on record. If you bought the vehicle used or have moved, update your details with GMC Canada so notices reach you, and check the manufacturer's lookup from time to time.
