What is wrong

On certain vehicles, a problem with the rear brake system may cause gas bubbles to form in the brake fluid. This could cause a soft brake pedal feel and a reduction in brake performance, increasing the risk of a crash causing injury and/or damage to property.

What the dealer will do

Dealers will bleed the rear brakes.

What is wrong

On certain vehicles, a joint on the high-pressure fuel pump may have been improperly welded during the manufacturing process. Over time, this could cause the weld to crack and create a potential fuel leak. A fuel leak in the presence of an ignition source could increase the risk of fire, causing injury and/or damage to property.

What the dealer will do

Dealers will replace the high-pressure fuel pump and high-pressure fuel pipe.

Airbag

Transport Canada recall 2018279 · manufacturer campaign 18179

25 May 2018

Transport Canada lists: Terrain 2018

What is wrong

On certain vehicles, the Sensing Diagnostic Module (SDM), which controls the airbag system, may not shut down correctly when the vehicle is turned off. If this happens, the SDM may not work when the vehicle is started, making it unable to detect a crash or deploy the airbags, and increasing the risk of injury in a crash.

What the dealer will do

Dealers will reprogram the SDM with updated software to correct this problem. Note: If the SDM is inoperative when the vehicle is started, the airbag warning lamp would illuminate, a “service restraint system” message would be displayed and warning chimes would sound.
