Defect
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.
Safety Risk
No risk description available.
Remedy
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.
