2018 GMC Sierra Hd recall questions
NHTSA lists no recalls for the 2018 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 9 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.
