general problems of the 2006 Mercury Mariner

Engine suddenly cuts off while driving. Message on dash says to safely stop the vehicle.

My vehicle: 2006 Mercury Mariner hybrid SUV. Purchased new in 2006. In hot weather. . . Vehicle engine quits while in motion on freeway at approximately 70 mph (3 times), and city streets (3 times). Extremely dangerous when engine quits while driving on freeway in traffic. All you can do (while praying!) is coast to a stop and do your best to pull off on to shoulder of road without crashing into other vehicles. We have tried 3 times to get Ford motor to repair this problem. . . All to no avail. The last time we had to pay approximately $1,500. However, Ford motor did reimburse us! but at the same time they claimed the problem was resolved. Not true! about two years later the problem started all over again. For10 years we have been driving a defective vehicle that was--at all times--a danger to our lives. Ford motor should have taken this problem much more seriously and either replaced the vehicle with a another one, or truly fixed the problem. I feel Ford motor has liability in this matter. The last time this problem occurred was July 16, 2017.

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.

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 properally. 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.

I was entering the interstate 430 at the maumelle, arkansas on ramp and began accelerating to merge with rush hour traffic. I noticed that I had accelerated faster than normal. . . 70 mph. I took my foot off the accelerator to slow down, but I didn't slow down. I thought I must have hit the cruise control button, so I hit the off button and brake and slowed slightly. . . 60mph the cruise control was not on. I let off the brake and car began accelerating back up to 65 mph very quickly. By this time, I was entering the interstate 40 on ramp/crystal hill exit in north little rock, arkansas. I realized that my brakes were not slowing my SUV and I had to get the car to a stop. I stayed on the crystal hill exit. . . Pushing on brakes as hard as I could. I only slowed to about 40 or 50 mph. I turned my hazard lights and began edging to the shoulder. So still pushing on my brakes, I put the SUV in neutral. I finally stopped about 100 feet from the stop sign at the crystal hill road. When I stopped, I noticed the engine was revving a lot so I put it in park and turned the SUV off. I tried to stay calm for me and my baby since I was 35 weeks pregnant. I was lucky that I didn't have to crash the car to stop it or I didn't go into labor, but putting it in neutral worked. My husband had my SUV towed to crain Ford dealership. They have diagnosed the problem to be the air intake valve and the throttle position sensor. The tow truck driver and the mechanic at the dealership said the SUV was messed and barely got it in the garage to repair which the dealership is working on. . . One week later. The diagnosis was verbal from the dealership. . . Nothing in writing as of yet.
