Recalls

Good news: Recall repairs are almost always free. Book with any manufacturer dealer and quote the recall number. Transport Canada’s own wording is that a manufacturer “will almost always make these repairs free of charge”, so being asked to pay for recall work is unusual and worth questioning. Since 2018 the Minister of Transport can order a company to pay for repairs so owners do not bear the cost.

What is wrong

On certain trucks, water could leak into the exterior tailgate switch. As a result, the tailgate could unlatch and open unexpectedly while parked. If this happens, cargo that is not secured could fall out of the truck bed and onto the road when the vehicle is moving. Note: This recall only affects trucks equipped with a power-locking tailgate.

Why it matters

Cargo that falls from the truck bed could create a road hazard for others and increase the risk of a crash.

What the dealer will do

General Motors will notify owners by mail and advise you to take your truck to a dealership to replace the exterior tailgate switch. To reduce the safety risk, General Motors recommends that you should inspect the tailgate to ensure it's closed and latched before driving.

Running cost uses Ontario average prices (155 ¢/L, 14.5 ¢/kWh), which are hand-maintained estimates. These are average residential rates. A car’s charging is added on top of what your home already uses, so on a tiered, time-of-use or subsidised tariff it is billed at your top rate rather than this average — which makes the real cost higher, especially in the territories.
