If certain passenger vehicles are parked and the engine is operated at high rpm's for an excessive length of time, some of the parts around the exhaust system can melt and produce a variety of malfunctions. Problems caused by the excessive heat build-up can range from inoperative oxygen sensor, neutral switch and back up lights, problems with the parking brakes, malfunctions of the gas gauge and/or possible fuel leaks resulting from heat damage to the fuel tank.

Fuel leakage, in the presence of an ignition source, could result in a fire.

Dealers will inspect and replace parts. The recall is expected to begin during August 2005. Owners should contact Mazda at 1-800-222-5500.
