I was driving along when I could smell my car getting hot, so I pulled over and sure enough it was overheating, but did not show inside on the dashboard, so I had it checked and the plastic housing around the thermostat was cracked in 3 places, so I say fix it ,they said it would be 450.00, Ok no problem, then they called back and said that the housing was welded to the manifold and that I would have to replace all for 1200.00 And that the housing wasn't made of plastic anymore because of this problem. I think this should be a recall and fixed for free. *Tr

My check engine light came on and the diagnostic code says that the catalytic converter was defective, even though it is supposed to be covered by an 8 year 80,000 mile warranty I have been stone walled by earnhardt ford in arizona in getting it fixed. I have already had to replace 4 o2 sensors at my expense in the last 6 months. When my engine light came on the first time I took the car into my mechanic who said the code was for the catalytic converter and that it would be covered by my warranty so I should...

contact a ford dealer. I called a ford dealer and they said call a mercury dealer, when I called the mercury dealer they said the light had to be on or they wouldn't fix the problem. The light came back on 2 weeks later and I took it to earnhardt mercury in tempe az who checked the light and said that it was the catalytic converter but they hat to reprogram the pcm to confirm the diagnosis and that they couldn't do it at that dealer and shipped my car to earnhardt ford in chandler who said they were to busy to reprogram the pcm and had to keep my car overnight. They then said that I would have to wait until the light comes on again before they would be able to order parts to fix it. So I will have to leave my car with them a 3rd time. So far they still have my car for a 2nd day and I cannot get a call back from the manager of the service dept. *Jb
After only owning my vehicle for 8 months, and being told it was in perfect condition, in a matter of 3 days, many problems occurred. My 4wd lights began flashing, along with the check engine light. When accelerating uphill, the temperature gauge raises to high in a matter of seconds and the check gauge light comes on. The car began dying, the idle dropping at slow speeds, and even died in mid driving down the highway, leaving me to veer towards the edge of the road with no power steering. I took the car to a...

dealership, that was supposed to honor my extended warranty, I paid $1200 for. My estimate came up to almost $3000 with the warranty only opting to cover $ 300. The problems as described by the mechanic were: throttle position sensor: $680, slack in both lower ball joints (need replacing): $625, electrical and related repairs: $ 215, sensor for front and rear internal failure $ 700, t/case motor $725. I come to find out that the 4wd on my vehicle purchased only for that reason with winter coming doesn't even work, the whole thing needs rebuilt. I've never even used it. I paid all I could $900, and got the car back just to have it responding the same way, virtually un-drivable. After viewing several websites, the ford/mercury website listed no recalls and complaints for my vehicle, but alldata.Com listed the throttle position, and the same 4wd problems I'm having; plus minor ones I failed to mention to the mechanic, such as the rear seat positioning will not recline, whistling from the wheel well etc... I am very disappointed in my findings, and find my self in question as to keep the piece of junk, or buy a new car. Did I get screwed by the dealer who sold it to me, along with my "fake" extended warranty? Is there any possibility the manufacturer can partake in the repairs? I already know similar problems are happening to other owners of the 1998 mercury mountaineer. *Jb
