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.

Battery: The battery warning light may come on due to lack of charging from alternator if vehicle is started, put in gear and driven before engine speed has returned to idle. (2003)

Blower motor: The blower motor may quit working or switch to another speed without input from the driver requiring a new wiring harness from the blower motor speed controller. (2003-04)

Electrical problem: The radiator fan motor may stop working requiring a new wire between the powertrain control module (computer) and fan motor. (2003)

Engine noise: Some 4.6L engines may develop a ticking sound from the engine at idle requiring replacement of the cylinder head and camshaft assembly. (2003-04)

Wheels: The rear wheels may chatter during low speed turns requiring installation of a revised clutch pack in the 8.8-inch, limited slip differential. (2003-05)

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.

2003 fleet/police cars: Wheel bearings and axles could become overloaded due to high loads, leading to early bearing failure and ultimately to axle-shaft fracture.

2005: Battery cable's fusible link on some cars may contact and subsequently chafe on cross-member bolt, which may result in heat damage and possible fire.

2007: A front wheel bearing and hub assembly may fracture due to improper heat treatment. As a result, the wheel may separate from the vehicle potentially resulting in a crash. Dealers will inspect and replace affected parts.
