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 conditioner may quit working due to water leaking into the evaporator sensor. (2001-06)
Ball joints:
Knocking noises from the front suspension on rough roads is likely due to worn torsion bar links because the seals tear and water enters the ball joints. (2001)
Brakes:
A whistling sound from under the hood when the brakes are released due to a problem with the power brake booster. (2006)
Engine noise:
Tapping/rattling noise on startup with 1.8L engine due to faulty hydraulic cam adjusters. (2004)
Fuel pump:
Tapping from the area of the gas tank requires installation of a restrictor in the fuel vent line. (2006)
Keys:
If the key is left in the ignition switch for extended periods (up to 36 hours) the key's battery may drain and the program in the key would then be erased. (2000-01)
Radiator:
The upper radiator support brackets bolts are weak and may break. Dealers were replacing all four bolts whenever one broke. (2001-02)
Rough idle:
The V6 engine may run rough or hesitate due to water getting into the crankshaft position sensor, requiring a new sensor and improved wiring assembly. (2001)
Steering problems:
The power steering hose may leak at the connection with the rank-and-pinion assembly due to 0-ring damage. (2001)
Transmission noise:
A scraping noise from the transmission tunnel area due to insulation drooping and contacting the drive shaft. (2004)
