I purchased my '99 Dodge Durango in 2/09 at 110,000 miles. After 24 hour driving it off the lot, the check engine light came on. The dealer had me take it to his mechanic and the idle air control valve was replaced. One week later, check engine light came on again. This time it was the oxygen sensors. Check engine light remained on even after the O2 sensors were replaced so the throttle position sensor was replaced. All seemed fine until 10/09 and the same process had to be repeated of changing the idle air control, O2 sensors and throttle position sensor. Then on 2/10, the rear brake on driver side locked up. All hardware, pads, rotors, drums, caliper and wheel cylinders were replaced.
A year later, rear brake locked up again and everything changed again plus all brake lines and brake master cylinder which seems to have cured that problem. On 4/10, a chirp was heard in the engine, turned out to be idler pulley and since it was so loose, everything in the front of the engine with a pulley on it had to be changed. Power steering pump, air conditioning unit, fan clutch etc. On 3/11, while driving, the transmission suddenly went into "limp home mode" and had to have a rebuild done. On 12/11, once again the idle air control, O2 sensors and throttle position sensor were replaced. Other random fixes have been upper and lower balljoints, u-joints, all four window motor/tracks and heater core. Now, the check gauges light came on and the oil pressure dropped to zero! From what I have read, it is a common Durango problem. It seems like Durangos have lots of problems and I think Chrysler should be held responsible for this mess they have caused. I have so much money into this truck, I cannot afford to try to sell it!
