2001 Dodge Neon Problems
RepairPal has identified the most common problems with the 2001 Dodge Neon based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
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.
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.
The fuel level sensors can wear out causing erratic or inaccurate fuel gauge readings.
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.
If there is a water leak into the passenger side of the interior, under the dash panel, it may be the HVAC housing drain is plugged or restricted.
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.
The engine may stumble occasionally during wide-open-throttle acceleration (full throttle). This may not occur frequently enough to set a Check Engine (MIL) light. The spark plugs (spark plug insulators) and spark plug wires should be inspected for deterioration and carbon tracking; resistance in the spark plug wires should be checked as well. New spark plug wires from Dodge are a revised design and any defective spark plugs need to be replaced.
