One problem related to diesel engine has been reported for the 2002 Dodge Dakota. The most recently reported issues are listed below.
I have 2002 ram 2 wheel drive with a high output turbo diesel. The check engine light came on at 23300 mile, it used 14 gallons of diels to go 56 miles. When I took it to the dealer they sayed the fuel injector pump was bad and it will be fixed free under warranty. The only other complaint is that the doors whisle and it is being looked at by consumer affairs to be fixed.
