Trouble Spots

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.

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. (2005-06)

Interior trim: The shifter knob comes off the shaft of the SS Supercharged model and must be retained with self-tapping screw and glue. (2005)

Keys: The key won't come out because of a problem with the microswitch pin in the floor shifter assembly. (2005-06)

Oil leak: Oil may leak from the 2.2L engine front crankshaft seal, especially in the winter, as the seal is damaged if ice forms at the mating surface then rips the seal lip when the engine is started, for which there is an improved seal. (2005)

Water leak: Water leaks onto the passenger side floor from the A/C housing, requiring installation of a seal between the heater core and A/C housing. (2005-06)
