There is a rattling (metal to metal) coming from the front left wheel setup. I'm not sure exactly what it is and either does the dealer. I have had it in 4 times now in 4 months for the same noise. It rattles when going over bumps, but does not rattle when I am applying the brake. They said they replaced a spring the first time, but that evidently was not the problem. Then they said they could not pinpoint the noise.
There is a vibration in the brake pedal when coming to a stop. I think it is related to the above problem.
When sitting at idle, there is a vibration of the whole vehicle (spontaneous, not a pattern to the vibration)
The transmission is slipping when going from a stop.
There is a grinding noise that goes with the rotation of the tires when turning under 15 mph.
When the wheels are turned all the way to the left, there is a jolt every rotation of the wheels. This sort of feels like the vehicle is in 4-wheel drive.
After spending so much money on this vehicle, there should be no problems, atleast not within the first couple months. It is a comfortable ride, but I don't think it will last too long after reading all these complaints.
I recently heard that durangos have problems with the front ball joints. Might try that. Its caused a lot of accidents. But, I'm not a mechanic.
