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.
Convertible top:
The convertible top may not close due to a problem with one of the microswitches in the lift mechanism. (1999-2000)
Doors:
The door may not open from the inside because the cable between the handle and release breaks. (1999-2000)
Engine misfire:
The pressure hose between the turbo and intercooler can come loose, causing significant loss of power. (2001)
Fuel gauge:
Erroneous fuel-gauge readings and/or problems during refueling may be due to the rubber fuel line inside the tank interfering with the sending unit or filler neck flap. (1999)
Spark plugs:
Fouled spark plugs cause hard starting or no-starts, requiring plugs with a hotter heat range. (2001)
