Trouble Spots
Consumer Guide's® Auto Editors have scoured repair bulletins and questioned mechanics to search
for commonly occurring problems for a particular vehicle. In some cases we also give possible manufacturer-suggested
solutions. In many instances these trouble spots are Technical Service Bulletins posted by the manufacturer,
however, we have our own expert looking at additional vehicle problems.
Check-engine light:
The check engine light may come on due to failure of the EGR valve. The Delphi valve is to be replaced with a Seimens valve kit and have the PCM flashed. (2005-06)
Electrical problem:
The PCM was being replaced for a defective chip under a voluntary emissions recall because it affected the fuel pump and EGR system. (2005)
Engine misfire:
The engine may not start, may start then quit, and/or assorted warning lights may glow because the wiring connector under the driver seat may get wet and the contacts corrode. (2005-06)
Engine noise:
A whistling noise from the 3.5L engine during acceleration is corrected by replacing the PCV tube. (2005)
Fuel gauge:
The engine may not start or may stall because the tank is empty yet the gauge shows fuel remaining, or the fuel gauge will not show full after refilling due to sulfur corrosion of the fuel level sender and if after treating with Fuel System Cleaner PLUS the problem remains, the sender may need to be replaced. (2005-06)
Headlights:
The headlights and interior lights may flicker requiring replacement of the alternator. (2005)
Horn:
The horn may require extra pressure on some spots of the steering wheel pad and softer springs are available to retrofit. (2005-06)
