Issue: On certain vehicles, the recall repairs completed by a General Motors dealer during recall N242454440 (Transport Canada recall no. 2024-637) may not have been done correctly. As a result, a second repair is required. 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.

2020 GMC Sierra Hd recall questions
NHTSA lists no recalls for the 2020 GMC Sierra Hd in our latest copy of its database. That is not a clearance for your vehicle: campaigns can be issued at any time, and NHTSA's VIN lookup is the record. Transport Canada lists 8 Canadian campaigns for the Canadian-market model, shown separately.
Enter your VIN in NHTSA's recall lookup or GMC's own, or call a GMC dealer with your VIN. 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. Transport Canada campaigns cover vehicles sold in Canada. For a vehicle sold in the United States, go by the NHTSA listing and NHTSA's VIN 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 so notices reach you, and check NHTSA's lookup from time to time.
