On certain vehicles operated in areas of heavy road salt usage (Ontario, Quebec, New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland & Labrador), road salt can collect in the outboard portion of the front lower control arm and may result in internal corrosion leading to thinning of the steel in the lower control arms. In severe cases, the corrosion may progress to the point where the lower control arm's upper and lower panels become perforated. A perforated front lower control arm may fracture between its ball joint attachment and the forward and rearward pivot attachments to the chassis. This could result in a loss of vehicle control and a crash causing property damage, personal injury or death. Correction: Dealers will inspect and, if necessary, replace the front lower control arms. Should the control arms not require replacement, drainage holes will be added, as well as treatment with rust-proofing material to arrest the corrosion process.

On certain non- ABS vehicles located in Quebec, Nova Scotia, New Brunswick, Prince Edward Island and Newfoundland, after sustained exposure to temperatures below -30 degrees Celsius, the power brake booster diaphragm may lose elasticity. After the first application following a sustained period of non-operation at temperatures below -30 degrees Celsius, the reduced elasticity of the diaphragm prevents the brake booster vacuum valve from fully closing. Therefore, the booster is unable to replenish vacuum and braking assist is reduced. The brakes operate, but require higher than normal brake pedal application effort, which may result in increased stopping distances. Normal brake booster operation returns as the brake booster diaphragm becomes warmer, approximately 10 minutes after the engine is started. Correction: Dealers will replace the brake booster assembly.
