General GMC Canyon AT4X AEV recall: Incorrect sensing and diagnostic module (SDM) software may cause a second

Recall published 11 months ago

Incorrect sensing and diagnostic module (SDM) software may cause a second stage passenger air bag deployment when only a first stage is intended. As such, these vehicles fail to conform to Federal…

The hazard: Airbag or restraint defect

This campaign concerns the airbag or restraint system, which only matters in a crash — and is therefore easy to postpone and expensive to postpone.

What the notice says: An air bag that deploys improperly increases the risk of injury in a crash.

Why it matters: The airbag or its inflator may not deploy correctly, may deploy without a crash, or may send fragments into the cabin when it fires. The system is meant to be the last line of protection, so a fault in it is only discovered at the worst possible moment.

What to do about Airbag

General — This campaign concerns the airbag or restraint system, which only matters in a crash — and is therefore easy to postpone and expensive to postpone.

  1. Treat this as a high-priority repair rather than something to fit around your next service.
  2. Call any franchised dealer for the brand, give them the campaign number from this page, and ask them to confirm parts are in stock before you book — part supply, not labour, is what delays a fresh recall.
  3. If the airbag warning light is on, say so when you book — it changes the diagnosis and sometimes the parts needed.
  4. Do not fit seat covers or dashboard accessories over an airbag module while the campaign is open.

Costs, reimbursement and your rights

The repair itself is free. What people most often miss is that money already spent can frequently be claimed back.

  • If you paid for the same repair out of pocket before the recall was announced, ask the manufacturer for reimbursement. Carmakers must run a reimbursement plan for pre-notification repairs; you will need the original invoice.
  • An unrepaired open recall can affect a sale or trade-in. Closing it out costs nothing and protects the value of the vehicle.
  • Towing is normally covered where the vehicle is unsafe to drive, and loaner cars or rental reimbursement are often available on long parts delays. Neither is usually offered unless you ask.
  • A dealer may not charge a diagnostic, inspection or shop-supplies fee for recall work. If one appears on the estimate, query it before you sign.
