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.

Rough idle: Rough idle or roughness/stumble on acceleration caused by poor oil flow to variable valve system caused by clogged screen on screw for oil tube connection on 2.5L turbo engine. (2004)

Transmission leak: Fluid may leak from transmission stud near the oil filter requiring sealing of threads. (2004-05)

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.
