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.

Check-engine light: The check engine light may come on accompanied by an engine misfire due to weak exhaust valve springs which must be replaced. (2004-05)

Electrical problem: If the OnStar system quits or won't come on (no power), but comes back to life if the fuse is removed for five minutes, the vehicle communications interface module must be replaced or else the problem will recur. (2005-06)

Fuel gauge: The engine may not start or may stall because the tank is empty yet the gauge shows fuel remaining, or the fuel gauge will not show full after refilling due to sulfur corrosion of the fuel level sender and if after treating with Fuel System Cleaner PLUS the problem remains, the sender may need to be replaced. (2004-06)

Fuel gauge: The fuel gauge may not move on trucks with the 4-cylineder or 5-cylinder engine, and all California models, requiring recalibration of the PCM. (2004)

Hood/trunk: Pickup box must be reinforced with available kit before installing a tool box, cap, etc. to prevent collapse. (2004-06)

Keyless entry: The keyless remote transmitter may not work, but function may be restored if reprogrammed only to quit working again due to water leaking into the body control module from a leak in the cowl. (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.
