Battery problems of the 2002 Dodge Intrepid

Bought a Dodge Intrepid the engine has been replaced twice it's an 2. 7 v. 6 . . . . The car stalls , the light flickers on an off as well as my radio!! my sensor are faulty because it give my car faulty reading to the wrong errs not only, that I have had build up in both engines grime and broken down particles! my speed is off sometime my car picks up speed by it self or it don't gain speed at all! the car also loses power for no reason at all! drain my battery four times! over heat without warning! had my thermostat replace twice!!! to many problem keep occurring and I can keep up with any of this!! texas dmv told me about this site told me about that these cars are not any good!! please help what do I do with this car?.

While wife was driving car to store on 2 June 2006, Intrepid engine shuttered and check engine light illuminated. Shuttering stopped and engine runs smooth but light is still illuminated. Mar 2006 engine oil change was accomplished along with a engine flush by ed's tire service, fayetteville, north carolina. July 2005 car failed inspection because of a bad battery, which was difficult to replace. Between 2002-2004 front rotors have been replaced twice, once by the Dodge dealership for $150. 00 then once by me for $60. 00. This sludge buildup problem that Dodge refuses to fix is becoming stupid! they are making the money off of us, they to at least own up to their design flaw and fix the problem. Does anyone know how to get sludge out of the engine other than tearing it down?.

Loose ground wire to battery posed electrical problems. Also, odometer tampering. Vehicle died while driving. Also, suspension/ steering problems. Dealer replaced all four bulbs on headlamps and high/low beam dimmer switch ,and cleaned out engine hoses, pcv valve and fuel filter.
