Due to the inappropriate shape of the linkage in the rear door lock controller, accumulated dust may prevent the door lock mechanism from functioning properly, causing incomplete locking of the door when the childproof locking system is used. This could result in an opening of the door while driving, increasing the risk of personal injury to a vehicle occupant.
Dealers will install parts in the latching assembly that will prevent this problem from occurring. Owner notification began July 26, 1999. 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 Mazda at 1-800-222-5500.
