Known Problems

The rear power door may not open or close properly, or make a grinding noise from inside the rear trim panel. If this occurs our technicians recommend to check for loose or damaged hardware at the rear door motor. Replace damaged hardware as required and use bolt retaining compound when reassembling the door motor hardware.

The anti-lock brake system (ABS) and/or brake warning light may illuminate, this may or may not be associated with a brake pedal pulsation. If a trouble code C1179 is stored, reprogramming the ABS system may be necessary to correct this concern.

It is not uncommon one or both of the exhaust manifolds to crack resulting in an exhaust leak. Symptoms will begin as a ticking type noise noted on acceleration when the engine is cold.

The fuel gauge may be slow to register, fail to read full when the gas tank is actually full, or read inaccurately. Our technicians tell us there is a redesigned fuel tank sender unit to remedy this problem.

A clunking or popping noise may develop when driving over pot holes or rough roads, the front coil springs may be the source of the noise. Our technicians tell us updated parts are available to address this problem.
