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.

Electrical problem: Various convenience functions initiated by pressing the buttons on the key may activate unintentionally and dealers have been instructed to deactivate some and/or change the time the button is pressed for activation. (2005-06)

Exhaust system: A campaign was conducted to replace a clamp on an exhaust system hanger that may allow the pipe to move and point downward. (2005-06)

Headlights: The nozzles for the headlight washers may pop out during freezing weather. (2005)

Vehicle noise: Rattling noises from the front are caused by nuts on the stabilizer bar links working loose. (2005)
