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 center air vent may be loose and flop out of position and the company was replacing the A/C register assembly as needed. The audio system cover may not close so it should be checked and fixed at the same time that the center console is removed. (2005)

Audio system: On cars equipped with the base level audio system, the radio stations may occasionally change by themselves requiring replacement of the audio head. (2006)

Doors: The front doors may not open fully and/or the window may not go all the way down due to a faulty door check rod. (2005-07)

Exhaust system: Rotten egg odor, while often caused by fuel with excess sulfur, is reduced by replacing catalytic converter with revised component. (2005)

Rear axle noise: Rattle from the rear hatch due to problem with mounting point for gas charged hatch support. (2005)

Steering problems: Some early production vehicles pulled to the right and, if an alignment does not correct it, it may be necessary to replace the power steering pump and link. (2005)

This table lists costs of likely repairs for comparison with other vehicles. The dollar amount includes the cost of the part(s) and labor (based on $50 per hour) for the typical repair without extras or add-ons. Like the pricing information, replacement costs can vary widely depending on region. Expect charges at a new-car dealership to be slightly higher.

2005-06 tC: Certain vehicles may have improperly assembled airbags that will not inflate sufficiently for occupant protection. Dealers will replace affected airbag modules.

2005-06 tC: Glass wind deflector for sunroof may shatter if hit by road debris with sunroof open. Dealers will install protective laminate to prevent pieces of glass from falling through sunroof onto occupants.

2005-06: The side impact seatbolster and curtain side air bags may inadvertently deploy if the door is closed with too much force while the vehicle is running or shortly after the vehicle was shut off. Dealers will replace the two side impact air bag sensors and install a urethane pad in the front doors, if necessary, free of charge.
