Flex 6-cyl

  • Automatic transmission
  • 7,526 miles
The contact owns a 2009 Ford Flex. The contact stated that there was an oil leak on the rear of the engine. The engine was removed and the leak was repaired by the dealership. The air cylinder that lifted the third row seats was defective and had to be replaced. The rear hatch opened on its own five times; the dealer realigned the door to remedy the problem. The rear main oil seal failed so it was also replaced at the dealership. The brakes failed to stop the vehicle effectively. When the vehicle was taken to the dealership, they stated that the vehicle was fine. The battery was defective and was replaced. The transmission excessively shifted into gear when down shifting, causing the vehicle to jerk and shake. The dealer stated that they could not find a problem when they inspected the vehicle. The engine made a popping noise when he accelerated from a stop. The door molding and window molding sills became warped. Lastly, one of the tires (the contact could not recall which one) blew and the sidewall separated; he replaced the tire at his expense. The contact called the manufacturer who stated that once the vehicle left the manufacturing plant, it was the dealership responsibility and offered no assistance. The current mileage was 15,283. The failure mileage was 7,526. The battery had to replaced. Updated 12/30/10

I bought my 2009 Ford Flex in June 2009. The first time I noticed a problem was in July 10, 2009. I was traveling down a residential street and was approaching a stop sign and doing appx 28mph when they car engine died. The steering wheel tightened up and the power brakes went out. I stopped the car as quickly as possible, and then started the car again. After that it ran just fine for a month. Then in August 2009, I was yet again going down a residential street and was approaching the stop sign going appx 28mph and the engine shut off again, the steering wheel tightened up and the power brakes went out. We took it to the Ford dealer, and they couldn't find anything wrong with it. Then, it did the same thing to me again on Monday September 28th 2009, this was the second time to bring it to a Ford dealer. They hooked the troubleshooter up to it, and it didn't throw any codes that anything was wrong, so the dealership replaced the throttle body on the car. Since then it hasn't stalled yet... but it was only put on less than a week ago. Hopefully it doesn't stall on me for a 4th time!!!!
