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 climate control system may blow hot when cold is chosen or all the flaps may close of airflow due to a fault in the climate control module software, which must be recalibrated. (2006)

Audio system: The audio system screen may freeze and there may be no sound from the speakers, but problems may clear when car is restarted, and flashing the control module eliminates the problem. (2004-05)

Battery: The battery may go dead overnight if the "infotainment" system won't allow the central control module go to sleep mode. (2005-06)

Brake noise: Noisy front brakes are corrected by installing a bigger caliper support that fits cars with 16-inch wheels, while rear brake noise is corrected with revised pads. (2004-05)

Electrical problem: On a few cars, the harness connector inside the A-pillar can get wet and corrode, so a campaign was issued to pack the connector with grease or replace if it was corroded. (2004-05)

Keyless entry: The keyless entry may work intermittently because a small screw in the unit works loose and parts fall out of place inside. (2004-06)

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 S40 and V50: The fuel line tube on some T5 models may leak in the area near the exhaust manifold, which could cause a fire. Dealer will change the fuel line material to Teflon from polyamide.
