On certain sedans, coupes, hatchbacks, and sport utility vehicles, electrical contacts in the ignition switch can degrade due to the high electrical current passing through the switch when the vehicle is started.

Worn contacts could cause the engine to stall without warning, increasing the risk of a crash.

Dealers will replace the ignition switch. Owner notification is expected to begin during June 2002. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact Acura at 1-800-382-2238.

On certain passenger vehicles and minivans; the ignition switch may wear excessively and prevent proper interlock operation, making it possible to turn the ignition key to the "OFF" position and remove the key without shifting the transmission to park.

If the vehicle operator does not shift to park before removing the key and fails to engage the parking brake, the vehicle could roll and a crash could occur.

Dealers will perform an inspection procedure that determines the amount of cylinder body wear. If significant wear is indicated, the dealer will replace the cylinder body, collar and latch plate. If no signs of wear are indicated, dealers will replace the latch plate with a redesigned part. Owner notification is expected to begin during November 2003. Owners should contact Acura at 1-800-382-2238.
