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.

21 May 2026

Transport Canada lists: Silverado 2018–2019 · Sierra 2018–2019

What is wrong

Why it matters

An airbag inflator that ruptures can create a risk of injury.

What the dealer will do

24 May 2024

Transport Canada lists: Silverado 2014–2019 · Sierra 2014–2019

What is wrong

On certain trucks, the repairs completed by a General Motors dealer during recall N192220470 (Transport Canada recall no. 2019-325) or customer satisfaction program no. N192270330 may not have been completed properly. As a result, a second repair is required. Additionally, certain trucks may not have had the updated parts installed during production. On certain trucks equipped with a power sliding rear window, the rear defroster wiring could overheat and melt.

Why it matters

Wiring that overheats and melts can create the risk of a fire.

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 contact cover for the sliding rear window. The dealer will also update the heating, ventilation, and air conditioning (HVAC) software, if necessary. If the rear window or sliding glass assembly are damaged, they will be replaced.

1 October 2020

Transport Canada lists: Escalade ESV 2018 · Silverado 2018 · Sierra 2018 · Yukon 2018

What is wrong

On certain vehicles, there could be a reduction in power brake assist due to a decrease in output from the vacuum pump. This could cause a hard brake pedal and create an increase in brake pedal effort that is required to stop the vehicle. Note: This is an expansion of Transport Canada Recall 2019-324.

Why it matters

A sudden increase in brake pedal force could lead to an increase in stopping distance. This could increase the risk of a crash.

What the dealer will do

The company will notify owners by mail and instruct you to take your vehicle to a dealer to reprogram the electronic brake control module.

What is wrong

On certain vehicles, there may be an error in the electronic-brake control module software. This could cause the driveline-protection system to activate when a wheel-speed sensor fails. If this happens, the brakes could apply and cause the vehicle to pull to one side. Note: This recall only affects vehicles equipped with four-wheel drive, a 5.3-L engine, and a 3.08 ratio rear axle. The problem can only occur when the vehicle is in four-wheel drive or automatic mode, and travelling at a speed between 66 and 97 km/h (41 and 60 mph). A wheel-speed sensor failure will cause the electronic stability control (ESC) and anti-lock braking system (ABS) warning lights to turn on, and a "Service StabiliTrak" message to display.

Why it matters

A vehicle that suddenly pulls to one side could increase the risk of a crash.

What the dealer will do

General Motors will notify owners by mail and instruct you to take your vehicle to a dealer to update the electronic-brake control module software. General Motors advises that using two-wheel-drive mode can eliminate the risk until the recall repair is completed.

What is wrong

This recall is for aftermarket replacement rear window glass produced by Vitro Automotriz. Certain rear window glass may not have been properly tempered. If the window breaks, the glass may separate into large pieces instead of very small ones. Note: This is a voluntary recall that is not being conducted under the requirements of the Motor Vehicle Safety Act.

Why it matters

Glass that breaks in to large pieces could create a risk of injury.

What the dealer will do

The company will notify consumers by mail and instruct them to inspect the designation code marked on the rear window glass. Products affected by this recall have the designation “DOT 287” along with the lettering “VMR” (Replacement Market) and a date code that is before July 2019. This information is printed on the bottom corner of the glass. Consumers should contact Vitro's customer service at 1-412-995-6457 or argbacklites@vitro.com to arrange for replacement of the glass.

Source: Transport Canada — Vehicle Recalls Database; NRCan — Fuel consumption ratings. Data current as of 6 August 2026. 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.
