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)
Electrical problem:
If the OnStar system quits or won't come one (no power), but comes back to life if the fuse is removed for five minutes, the vehicle communications interface module must be replaced or else the problem will recur. (2005-06)
Electrical problem:
On vehicles equipped with OnStar the global positioning system may lose precision (get off track) and may be caused by window tinting, or, if the antenna is in the rear parcel shelf, by things placed on the shelf. (2005)
Engine noise:
A whistling noise from the 3.5L engine during acceleration is corrected by replacing the PCV tube. (2005)
Engine stalling:
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. If after treating with Fuel System Cleaner PLUS the problem remains, the sender may need to be replaced. (2005-06)
Engine stalling:
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)
Horn:
The horn may require extra pressure on some spots of the steering wheel pad, and softer springs are available to retrofit. (2005-06)
