At 112,000 miles vehicle started loosing rpms at all speeds and conditions, usually after being driven for 30 miles or more. Sudden onset, no prior indication. Entire car shakes then at times stalls in heavy or no traffic, particularly at any inclines. Today I merged into heavy interstate traffic and vehicle suddenly stopped. The fuel pump has been replaced and no one has been able to offer any help as to what else it may be. I have found various forums with this make, model, year with the same exact problem with no solution indicated. This is the most common problem with this vehicle according to 3 major sites and at least 4 mechanics, often occurring on brand new vehicles. Dodge has been notified. There may not have been an accident yet but it will most likely happen.

Car fine until it warms up then the motor begins to shake, huge RPM loss, cuts off mid-traffic. Happens every time car is driven over 30 miles, then is undriveable for at least 6 hours. Stalls in the middle of highway or uphills, or down hills. Very dangerous going over 30 mph.

2005 Dodge Neon SE suddenly began to constantly accelerate despite the gas pedal not being pressed. Braking would slow the car but not effectively and the car would accelerate once the brake pedal was disengaged. While this was occurring, no sensors in the on-board diagnostic computer indicated any problem. The car was driven 30 more minutes with the engine being repeatedly turned off - in order to stop the car at red lights/stop signs - but putting the car in neutral caused the engine to attempt to red line and necessitated it be turned off. In order to continue traveling, the engine had to be started and the car rapidly put in drive or reverse before the engine red lined. After approximately 30 minutes, the check engine light came on. Nothing of note preceded the failure and the only work done on the car in the last 12 months was routine oil changes and one rotation of tires. Once the dealership examined the car, they found a faulty vacuum line but were unable to determine the failure for 30 minutes of the on-board diagnostic computer in determining that constant acceleration (or a failure in the fuel system) was outside the normal operating parameter of the engine. Dodge was contacted on the issue and contended the repair was outside the scope of the existing warranty and also could not explain the failure of the on-board diagnostic computer in detecting the failure of the fuel system. They seemed uninterested in investigating further.
