The upper power steering hose on some of these vehicles may have been misrouted so that it can come in close proximity to and/or contact the catalytic converter, GM stated in its recent recall bulletin. With the engine on, heat from the catalytic converter may melt the power steering hose. If this occurs, power steering fluid could flow onto the catalytic converter, and an engine compartment fire could occur.

For the recall, dealers will inspect to ensure that the upper power steering hose is routed correctly. If it isnt, dealers will replace the upper power steering hose. GM expects less than one percent of vehicles to require hose replacement.

Dealers are also to install a protective sleeve around both power steering hoses on all recalled vehicles, regardless of routing, to prevent abrasion of the hoses.
