Engine will not turn over. All electronics work. Keep turning ignition key on and off sometimes it will start in a few minutes other times it has to sit for a half hour or more. Dome light will come on for no reason. After reading others having same issues, I turned on easy access and slightly turned ignition key and sure enough the seat went back and dome light came on. This vehicle has been to a ford dealer numerous times, once towed, and they can't seem to duplicate the problem. Thanks to this website I now have more information and hopefully will be able to get this on going issue fixed. The easy access is always turned off. The no crank no start is the big problem because I can't go anywhere for just a half hour and be confident it will start.

Pulled into parking space, placed shifter in park, turned off ignition, released brake and vehicle rolled backwards as if not in park. Attempted to restart vehicle and no response. Set parking brake. Could not get vehicle to lock into park, shifter moved regardless of brake on or not and would not start. Moved shifter through entire range of gears and returned to park, vehicle still would not start and park would not hold. Called dealer and was told to have it towed in. Returned to vehicle and tried once more and it started and proceeded to respond normally. Vehicle taken directly to dealer who could not find any problem or cause of preceding situation. On two subsequent dates (most recent 5/25/2012), vehicle was backed into a parking space, placed in park and ignition turned off. When an attempt to restart vehicle was made there was no response. Park appeared to hold normal, but unable to engage ignition. Dash lights, chimes and all electrical components appear to work normal but was still unable to engage starter. Again started process to have vehicle towed to dealer. After approximately 30 minutes to an hour of sitting (with no other action) vehicle started normally. Again dealer at a loss for cause and cannot effect repair since unable to recreate problem. Concern is for transmission/ignition interlock failure or other action that could result in damage or injury.

Purchased 2002 mercury mountaineer from ford dealership in 2007. Transmission was slipping, took in two days later and still under warranty and informed new transmission put in. In august 2010, vehicle suddenly would not start, towed to dealership and informed the transmission was once again defective and sensors as well as cpu unit would need to be replaced. Researched on line on www.autobeef.com and noted many other defects on similar make, model and years with very similar problems. Approximate cost to fix $2,400 dollars.

My mountaineer stalls without warning while going about 35 MPH but after a few minutes can restart. It has done this 4 times over the last 3 or so months. In addition twice it would not start (it had been about 30 minutes since I drove it) and it had to be jumped. I replaced the battery thinking that was the problem but it persists. I brought it to a regular garage once, who kept it for a day and found nothing wrong. I then brought it to a mercury dealer who kept it for 2 days but found no codes or problems. It just stalled again two nights ago while I was driving 35 MPH without and restarted a few minutes later. The dealer had it for a day but again found no codes or problems. So far I just put in a new battery and they changed the oil and filter.

Tl*the contact owns a 2003 mercury mountaineer. The contact stated that the rear driver's side wheel bearing was replaced 3 times within 16 months. On october 1, 2008, while driving out of the driveway at an unknown speed, she heard a loud noise. The vehicle was towed to the repair shop and the mechanic stated that the rear driver's side wheel bearing failed. The contact stated that the vehicle was not driven on dirt roads, only in the city. She feels that either the wheel bearing is defective or the ford dealer did not properly correct the previous failures. The ford dealer stated that the vehicle is out of warranty and the wheel bearing is only good for 12,000 miles. The manufacturer took a report and stated that they will forward her information to the dealer. From there, the dealer will determine if the vehicle will be repaired. The failure mileage was 74,494 and current mileage was 104,000. Updated 11/14/08 *cn the driver side visor was hanging down, the vehicle stalled on several occasions. The lower ball joints and outer tie rod ends were replaced. The rear hatch window cracked. The vehicle would crank, but it would not start. Updated 11/18/08.

After not driving my vehicle for 2 days the battery level is low, the red indicator lamp on battery is showing, and my vehicle will not turn over. I connect my jump-it and it starts right up. I have taken it in to midland ford several times and they tell me that they cannot find anything wrong with my vehicle and they cannot replace any parts unless they can find a problem. They want me to leave my vehicle there for at least two days to try to replicate the problem, but refuse to provide a replacement vehicle or rental car or I have the option to have my vehicle towed in to midland ford at my expense so they can verify that the battery is actually low in order to replace it. My 2004 mountaineer only has only 21000 miles on it and the problem started occurring around 200 miles and is getting worse as time passes. Last weekend after driving home from work I decided to vacuum out my vehicle using electrical from my house for about a 1/2 hour and I did not even play the radio or have the ignition key turned on. When I was finished, I closed up the doors and did not enter the vehicle until the next morning when I was leaving for work and again the battery was dead with the red light on. I took it in again and midland ford said they could not find anything wrong and they cannot replace the battery. I feel very confident that if the warranty were to expire they would not have an issue with replacing the defective battery at my expense.

The car wouldn't start so I had it towed to the dealership. The technician tried it and it started right up for him. They couldn't find anything wrong with it. I'm not sure if I have it right but I was told the reason it didn't start was I had the wrong type of fuel, winter verses summer. The temperature dropped after thunder storms during the night. There's been quite a few times when the car didn't start up on the first turn of the key but I didn't think anything of it. There was another time when it didn't want to start but eventually did. It was a rainy, snowy night. This last time when it didn't start it had rained also. I'm wondering if it has more to do with the rain and not the fuel.

Ford has bought back car - hopefully, tomorrow will be the transition day. For the transmission, car had been in 3x - transmission kicked at various speeds. Starting in 12/01, 4x (including once in the dealership), the car would not start. Feel that this is a major problem w/ car. Receivng new car, but I thought this info. Should be part of the federal safety agency file.
