Most reported Dodge Neon problems
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 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.
When a no start condition is caused by a faulty camshaft or crankshaft sensor, related fault codes stored in the powertrain control module (PCM) should not be trusted. Our technicians tell us that under certain conditions a fault code can be stored for the "good" sensor. Care should be taken to properly diagnose this condition.
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.
Problems with the remote starter accessory may be fixed by replacing the hood switch for the remote starter. The vehicle will typically chirp the horn and not start, or it will chirp the horn, start the car, and then turn off.
Cars without ABS suffer master cylinder failure. The brake pedal will be spongy in feel, the pedal travel will seem excessive, and overall braking performance will be poor.
The engine may develop misfires when accelerating up a grade or when carrying a heavy load. This can be from carbon tracking that has developed on the spark plugs causing the plug to not fire (misfire). The engine will run roughly and lose power.
Erratic or intermittent windshield wiper operation can be caused by a poor ground connection at the grounding strap.
If the vehicle overheats because the cooling fan is not turning on, or if the AC is not working, it may be due to a defective RFI fan filter module (located at the center, near the bottom of the fan assembly).
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).
