Mariner Hybrid

  • 54,500 miles


Was stopped at a red light, car had been driving fine, but when the light turned green and I proceeded my car suddenly had reduced power and would not drive more than 40-45 mph. No lights or anything came on the dash the first time. The second time however a yellow/orange wrench light appeared. I got home and parked for the remainder of the day but then the following day the problem still proceeded and I then let it sit all weekend. The following Monday I turned it on to take to the repair shop and the car drove fine that entire day. The next day, Tuesday, while driving home from work it happened again only I couldnt go faster than 30mph in a 55 mph zone. Car was taken back to shop and diagnosed as a failure in the throttle body. During this time of reduced power fans in the trunk space got extremely loud and began sucking in air, as if trying to cool the batteries. Needless to say Ford has been no help and I can not get to work as I cannot safely drive my vehicle due to the limp home mode activating and random times. The prior investigation infuriates me to see they extended a wattanty instead of doing recall because now owners like myself are stuck not even being able to get to the dealership because the car is not safe to operate.

While driving and attempting top accelerate up to speed, the vehicle began to slow and hesitate. It would not properly accelerate. After going a short distance at reduced speed, the vehicle began to shake and hesitate. I was able to make it home (luckily not too far). The wrench symbol on the dash illuminated during this episode as wheel. I checked theowners manual and then called my local dealer who recommended the care be towed to dealer and not driven. This was done the next dayand after a full day of checking the vehicle, the dealer advised they had no idea what the problems was. They released the care to me. The next week the same situation happened several more time and finally, while on the way to dealer, it happened again with the service engine light coming on as well. This time the dealer identified the problem as the throttle body and replaced it at a cost inexcess of $500.

The contact owns a 2010 Mercury mariner. The contact stated that the vehicle stalled six times without warning. The vehicle was taken to a local mechanic because they were unable to take it to the dealer to have the throttle body replaced. The vehicle was not repaired for two weeks because the part was on back order. The failure and current mileage was 24,400.
