| Description of the problem | While traveling at highway speed the electronic throttle control system of the vehicle completely failed placing the vehicle into limp mode as indicated by the flashing warning lights and the dashboard display reading "esp disabled". The vehicle reduced speed drastically without driver input to do so. Were it not for the awareness and capability of the driver following the vehicle, this drastic reduction in speed would have caused a vehicular collision on an incredibly busy main thoroughfare. The affected vehicle suffered a complete loss of throttle control and the engine stayed at approximately 2000 rpm's regardless of driver input to the throttle pedal. Maximum speed dropped to no more than 15 mph. Stopping the vehicle completely at traffic control devices was difficult due to the constant high rpm the engine was maintaining. The vehicle was taken to the service department of the nearest jeep/chrystler/dodge dealership where it was troubleshot. The electronic throttle body was replaced consequent of the diagnostic check ran on the vehicle. The next 30 miles driven in vehicle were uneventful. The next day the exact same malfuntion occured again, albeit on a not so busy road (thankfully). Conversations with the service department reveal no confidence inspiring trouble shooting and/or repair procedure for what is apparently a known problem for many products across the corporate line, spanning many model yeas and generations. Basically, it was stated that they are aware of the issue but are unsure of what causes it or how to remedy the malfunction. The vehicle is now parked useless in owners driveway until a solution is found and the vehicle can be safely driven again. |
