2000 Plymouth Neon Problem Reports
Report A Problem
Spark plug tube seals fail, causing the tubes to fill with engine oil and the engine to misfire. As a result, the engine may run poorly and fuel economy can suffer.
Some vehicles may develop a musty odor coming from the HVAC system, Dodge has issued a cleaner/disinfectant and a coating for the evaporator designed to inhibit bacterial growth.
When the trunk lid weatherstrip (seal) is worn, the lid may rattle, water may leak into the trunk, or dust may get into the trunk. After installing a new trunk lid (deck lid) weatherstrip, be sure to adjust the trunk slam bumpers so the power trunk latch opens the trunk on the first attempt.
There have been reports of premature head gasket failure; an updated gasket design is available to correct this problem.
An engine Oil leak may develop at the cam sensor o-ring seal. Our technicians tell us this is often misdiagnosed as an external head gasket leak.
If a Check Engine Light illuminates indicating leak detection pump (LDP) failure, the cause is often pinched or disconnected vacuum lines to the pump. Vacuum lines should be inspected before replacing the leak detection pump. Contamination (carbon or debris) in the pump can cause failure and any hoses should be cleared before a new pump is installed.
Lubricating the flocked parts of the vertical window weatherstrips with Mopar Weatherstrip Lubricant can help with slow power windows or ease window cranking effort.
The sunroof may open only to the vent position and close, or it may open to the vent position and get stuck. This may occur after the sunroof was operated at high freeway speeds, which applies excessive force to the sunroof mechanism. The sunroof mechanism will need to be disassembled and reassembled, replacing mechanism parts as needed.
There was a recall to replace the vacuum hose for the brake booster. In the presence of oil, the original hose could swell and become disconnected. The brakes would function but power assist would be lost and the pedal would feel very hard.
A click heard when turning the steering wheel may be solved by aligning the steering column or installing revised parts in the column (requires removal of the steering column).
A clicking or popping sound from the front of the vehicle (left or right side) while accelerating from a stop may be fixed by installing a rubber gasket on the axle shaft.
If the needles for the instrument cluster are on the wrong side of the pointer stops, perform a "self test" on the instrument cluster. Press and hold the trip-reset button and then turn the ignition key on (do not crank the engine). Some indicators will light in the cluster and the needles should sweep to the proper side of the pointer stops.
