The check engine light came on at 10,000 miles, car began running very rough. #8 fuel injector was completely plugged and had to be replaced.
Problems with the injection system at 20,000 miles - car running rough again. Also, transmission sounded like it was going to fall out when put in reverse. Dealer claimed they "tuned" up the car and put sound insulation around transmission case.
Easter Sunday 2000 - stuck inside a car wash because car won't start. Problem due to failure of two computer sensors which had to be replaced.
40,000 miles check engine light on again. Car running rough. Needs same work as at 10,000 miles on fuel injectors. One week later, same problem. Replaced parts.
60,000 miles check engine light on again. Car running very rough. Fuel Injector problems again. Also, rear window motor failed and had to be replaced.
Extremely poor mileage - no difference on road or in town - never better than 13 mpg. Air conditioner works poorly.
All the problems with the fuel injection system have been attributed to "bad" gas. I even have it in writing that the solution to this problem is to buy gas at name brand stations. The bulk of my gas has been bought at Texaco, Amoco and Sinclair. I have the credit card receipts to prove it. I also have a bag full of "rust" taken out of one of the fuel injectors. I have never had a similar problem with any other vehicle that I have owned. Now my son's 99 Dakota is doing the same thing and they have also told him that the "problem" is just bad gas.
This car has been very undependable and the dealers have been unpleasant to work with on the warranty issues. Plus now - the injector problem is no longer covered by my extended warranty since they claim it is a "fuel" problem.
I have a 2000 Dodge Durango SLT that is VERY dependable. No problems even similar to the one's you describe. My only problem is the check engine light came on recently (36k miles) and hasn't gone off. I'm thinking it's one of those situations where the light comes on at a certain number of miles and has to be reset. I had a Mazda that did that. Even with the check engine light on, it's the best running, best driving vehicle I have ever owned. Sorry to hear you have had so many problems.
