2006 Mercury Mariner Owner Comments

problem #8

  • 60,000 miles


My Mercury Mariner's idler pulley has already broken three times in the past five months. There must be a recall on this vehicle. The car is very good and too strong for that thin bolt in this part. Luckily, the fourth time it happened, the Ford dealer didn't charge me for the new part, which also broke off two weeks later. It has also broken two belts already. Trying to solve the issue, I went to metric bolts and nuts, in wakefield, MA, and bought a higher grade hardened steel bolt/screw, and it also broke off a week later. Once again, two days ago, my mechanic put in another hardened steel screw. He added a nut near the bearing, which makes a squeaking noise, but it has not broken yet. I am now afraid to drive it far from home, because I have been towed so many times already. I have researched the internet and realized that it is a constant issue. Some people have reported the occurrence of this issue 17 times in less than a year. It is also the same frequent problem with Mazda tribute, Ford escape, Ford Fusion, etc. What does it take for a recall? help! help! help!

The truck shuts off when I come to a complete stop. It usually happens when I'm attempting to stop at a yellow light to avoid running the red light. If the truck come from a high rate of speed (45 mph) to (0 mph) it just turn off. I'm afraid someone is going to run into the back of me when the light turn green because the driver expects me to move when the light turn green. I think this is very dangerous for a vehicle to just stop. It has happened about 20 times since 03-29-2014. I was told by two mechanics that it's the torque converter and that there is a recall on the Ford escape for this same problem. I believe the parts are the same for Ford and Mercury and I want it to be known that Mercury vehicles are having the same problem.

Mariner 6-cyl

  • 77,541 miles
While building speed via an on-ramp on ca freeway 680, the transmission began to fail. Within roughly 200 yards, the car lost power and, thankfully, I was able to get my car to the side of the freeway. The first time I was able to get the car to work again, I was only able to drive about 50 yards. I then let the car 'rest' for about 20-30 minutes (while I contact my roadside assistance company). After that amount of time, I tried the car again and was able to drive to the next off-ramp (industrial way, benicia, ca). At the stop sign of that off-ramp, the car failed again and I chose to have it towed instead of continue trying to make it work properly. My Mariner is a 2006 with only 77,541 miles! my car eventually got to a transmission shop to be fixed, but it was in my research of the problem that I found failing/faulty transmissions to be a very common and known issue for Mariners with low mileage (model years of 2005-2011, at least). My complaint is that there should be a recall issued because this is a well known problem.
