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.
Air conditioner:
The air conditioning may not cool sufficiently and/or the outside temperature reading may be wrong due to a poor crimp connection or faulty outside temperature sensor. (2005)
Brakes:
The ABS (anti-lock brakes) may activate unnecessarily under normal to light application due to cracks in tone wheels. (1996-05)
Dashboard lights:
The "oil level" selection of the information center does not work because cars shipped to the US do not have this feature. (2005)
Fuel door:
The fuel door may not open because the release cable causes interference and must be routed out of the way. (2005)
Fuel gauge:
If the fuel gauge does not show full after filling up, the program for the instrument cluster must be updated. (2005)
Keys:
The key may not come out of the ignition switch because the system can't tell that the shift lever is in park. This requires replacement of the shift selector with redesigned part. (2005-06)
Keys:
The ignition key may not come out of the lock or the car may not lock due to trouble with the gear selector mechanism. (2005)
Oil leak:
Oil leaks may occur on the 3.2L engine at the timing chain upper covers requiring fresh sealant. Leaks from the camshaft sealing plugs require the old plugs to be removed (possibly from inside the engine) and redesigned plugs installed. (2005)
Oil leak:
Camshaft plugs in the cylinder heads of the 3.2L engine may come loose causing an oil leak. (2005)
