general problems of the 2008 Mercury Mariner Hybrid

Stop safely now chimes and displayed on dash followed by no acceleration until vehicle stalls and stops. Starts right back up but continues to happen especially in la rush hour traffic. Very dangerous! had recall work done on the mecs 3yrs ago but problem has continued. This happens while in motion on the 110 freeway in downtown los angleles, CA. Could be the electric throttle body or rear actuator. Or any other component that works with the electric motor and battery.

The power torque sensor for the power steering was already recalled and had the system updated before I got the car in 2014. The cars steering wheel starts shaking a little then all of a suddle the steering wheel locks up and the power steering stops working, so you can't hardly turn it. I came inches from getting in a wreck. You can update the system but it will only work for about 1 or 2 years.

Quits running while caution with explanation in middle light appears and wrench light appears. Then notification to stop at once safely. This has happened on freeway. After 15-20 minutes car will crank again but may only go a few feet and stall again, near death experience.

When decelerating down hill the brakes became seemed to have no power to stop the car and required extreme force to stop the car. Afterwards the electronic motor disengaged from the engine and the automobile runs on combustion engine only without the hybrid electric motor assist.

Just after starting my car and driving down my street at ~5mph, there was a warning symbol (red triangle) and then message saying "stop safely now. " the vehicle then lost power steering, and power to the engine. I restarted the car and made it ~100ft and the same thing happened again. This also happened several times previously on the highway traveling ~65mph and with the same message "stop safely now" message appeared and immediately lost all power to steering and the engine. I went to the Ford dealership and was told to replace the hybrid coolant pump and blend doors and this fixed the problem for several months until today. I had also just taken the vehicle into the dealership for a recall on the power steering. This loss of power and ability to steer is extremely dangerous! this needs to be recalled!.

While my wife was driving our 2008 Mercury hybrid mariner on a highway at a speed of approximately 45 mph, a warning light appeared on the dash (red triangle with and exclamation point) and the vehicle began slowing down in a manner that prevented her from controlling the speed of the vehicle. My wife, fortunately, was able to pull to the side of the highway without incident. The Ford dealership's diagnostic test revealed a faulty electronic throttle body and the dealership recommended immediate replacement for safety reasons. I understand that as a result of similar issues with Ford escape and Mercury mariner models, through a customer satisfaction program, Ford voluntarily has extended warranty work for some escape and mariner vehicles. The VIN for our 2008 Mercury hybrid mariner, however, was not included in this program. I spoke with a representative and with a supervisor from Ford customer service (800-392-3673), and the supervisor reported that Ford is not in a position to address the issue with respect to my vehicle, because there is not enough data to include my vehicle within the voluntary customer satisfaction program.

I was traveling west at about 70 mph in the left lane on I-66 out of washington, DC with four people in the car. Suddenly, the engine died and we were left with only the electric motor on the hybrid and a dash warning of a red triangle and the statement "stop safely soon. " the car quickly lost power to about 30 mph and we struggled to get across the four lanes to the shoulder. The electronics in the car still operated (radio, dash lights, etc. ), but the gas engine stalled. Once on the shoulder, we stopped. The Ford owner's manual told us to turn the car off and try to re-start. We did this and the car re-started. We started to drive, but the car did the same thing after about 5 minutes. The car did the same thing on about 5 different occasions until we could get to an exit that had businesses. The Ford dealer in this area (away from my home) states that the electronic cooling pump needs to be replaced. Although I understand that parts fail, my complaint is that Ford should not tell owners to re-start the car and try to proceed on. It is dangerous when it continues to fail and you don't know where the next failure might occur (on a bridge, in a construction zone, on a busy, fast interstate). Moreover, having reviewed complaints on this site and elsewhere on the internet about Ford hybrids, I know that many others have experience this situation where the car engine stalls at highway speeds due to various problems (e. G. , the electronic cooling pump, bad sensors, or a corrupted pcm).

This would be the third total engine power shut-down at freeway speeds with no limp-away option after exiting the freeway, realized that we were in an unsafe neighborhood [so not a good option to stop and call for tow], tried mapping surface street route to safer area, but nav system showed the only surface street route to take us back home put us on a steep, narrow winding section of laurel canyon - no safe exit if another shut-down. Also realized we couldn't use riverside thru griffith park which is locked after dark . . So zig-zagged north and west about 5 miles below 40 mph keeping to lighted streets hoping for safe place or unremembered route. Engine remained stable once more, drove towards I-5 again on los feliz (past the griffin bar 㢠and a topless club) . . Remembered los feliz ahead had a long, separate entrance ramp to n/b I-5 . The drivetrain accelerated smoothly to ~50 mph, then warnings / drive train died again at the bottom of the on-ramp . . Hazards � again . . But with less momentum, harder to find a wide-enough spot on the n/b outer shoulder across from s/end griffith park golf course. When minimal spot found stopped / parked / shut down and restarted again, engine started and idled smoothly, no warning lights remained on. Now about 10:15pm. With hazards on, rolled below fwy speeds along shoulder until it ran out just as adequate opening appeared in outside lane. Accelerated cautiously to below 50 mph, limped off at odd freeway appendix which leads east - merged right onto san fernando, turned left (north) at next signal and started working way about 12 miles back west on surface streets from the moorpark area never exceeding 45 mph. No additional drivetrain issues before we reached studio city home ~ 11:10pm. This was the third total engine power shut-down at freeway speeds with no `limp away' option.

The engine abruptly stopped while I was traveling 65 mph. The car was towed to a Ford dealer who diagnosed the problem as the "motor electronics cooling pump. " the part was replaced but was not covered by the warranty. Ford issued a technical service bulletin in November 2008 concerning this problem, so Ford has been aware of this danger for years.

Vehicle's gas engine shut off on the freeway at 65 mph without warning leaving only the electric motor to power it. The reduced the maximum speed to 25 mph. Dealer said failure of the motor electronics cooling pump caused the loss of power.

Around oct 2009. My sensor went bad and had to be replaced then again in October 2010 or 2011 with around 60000 miles going down I-75 around 70 miles an hour a red triangle came on telling me to pull over safetly now. I need a mecs pump something about a pump to cool the battery after again another costly bill on my way to work this spring the red trianle came on again. This time instead of taking this car to the dealership I took it to my mechanic it saved me around $100. 00 on the replacement of the cooling pump. I was driving in constuction August 22, 2013 and the red light came on again telling me to pull over safely I did have my air on and I was stuck in traffic so I pulled over. In the heat I have not had my air on again and it has not happened in the last couple of days but I do not trust my car and I now need to go to my mechanic and have it checked out. .

The car shuts off without warning on the highway at speed causing fear, danger and a potential for disaster. Still doing this most recent incident was June 25, 2014. Ford refuses to do anything about this reoccuring problem I have, as do may other owners of Ford hybrid vehicles.
