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.
Airbags: The airbag warning light may come on if a device with a memory card (e.g. laptop computer, PDA, etc.) is placed on the passenger seat which causes interference with the Baby Smart system. (2006-07)
Battery: There was a service recall to replace the voltage regulator in the alternator which, if not replaced, allows the battery to go dead. (2006)
Brake noise: Noises from the front brakes due to weak brake pad pressure retaining springs. (2006)
Check-engine light: The check engine light may come on because of a malfunction in the secondary air injection system due to a bad air pump relay. (2006-07)
Steering problems: The speed sensitive steering may malfunction due to a broken connector or other electrical connector fault at the valve on the rack-and-pinion assembly. (2006)
Sunroof/moonroof: The sunroof may leak or rattle due to an inadequate seal in the frame. (2006)
