the door handle is loose and the door wont lock sometimes, most of the time, i heard this is a major problem on mountaineer's. ford needs to tighten up. they need to keep up with CHEVY. this problem is a big mess. but have alarm, so if door isnt locked and alarm is armed , alarm will sound.. makes me feel somewhat better. i just bought the car and now all these problems are happening. a/c doesn't blow cold, rear speaker is blown, handle and door lock sit. but overall im satisfied with my new truck. rides good and handles well.
