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: A growling sound may come from the A/C compressor when it cycles off or on requiring replacement of the expansion valve. (2005)

Check-engine light: The transmission solenoid/pressure switch leaks fluid causing a check engine light, requiring replacement of the solenoid and electrical connector and fluid may also leak from the electrical connector guide on the right front corner of the transmission. (2005)

Starter: The remote starter may not work because of a failed hood switch. (2005)

Steering noise: Whining from the power steering when first started, especially in cold weather, due to insufficient fluid flow. (2006-06)

Steering noise: Clicking from the steering column due to interference between the turn signal lever and the cancel cam. (2005)

Transmission leak: A recall of 99,000 units was conducted because of a bad seal on the automatic transmission fill tube, which could allow water to get into the transmission and cause extensive damage. (2005)

Transmission leak: Transmission fluid leak, which appears to be a pan gasket, is from the electrical connector O-ring. (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 Grand Cherokee w/ 3.7-liter V6: Water from the A/C evaporator may enter the transmission leading to increased transmission operating temperatures, expulsion of transmission fluid, and underhood fire. Dealers will replace defective seals, flush affected transmissions, and possibly replace torque converters.

2007: The antilock brake system control module software may cause the rear brakes to lock up during certain braking conditions. This could result in a loss of vehicle control and cause a crash without warning. Dealers will reprogram the ABS electronic control unit.
