Mazda RX-8: Electrical
Affects Mazda RX-8 · 2004–2005 — about 4K vehicles.
The hazard
On certain vehicles, if while parked the engine is operated at high RPM's for an excessive length of time, some parts around the exhaust system can melt and produce a variety of malfunctions. The problems caused by the excessive heat build-up can range from an inoperative oxygen sensor, neutral switch and back-up lights, problems with the parking brakes, malfunctions of the gas gauge, and in the worst case, possible leaks from the fuel tank. Fuel leakage in the presence of an ignition source could result in a fire. Correction: Dealers will reprogram the Powertrain Control Module, install a heat insulator pad on the fuel tank, and inspect various components for heat damage.
