Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

2009 Ford Flex Owner Comments

problem #10

May 282016


  • 101,946 miles


The contact owns a 2009 Ford Flex. While driving 35 mph, the front of the vehicle began to vibrate. The vehicle was taken to an independent mechanic who diagnosed that the front axle had an indentation and the rear brake caliper had bolts that detached. As a result, the axle and caliper needed to be replaced. In addition, the technician stated that the torque converter and transmission seal were leaking oil and the drive line and torque converter needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failures. The failure mileage was 101,946. The VIN was unavailable.

July 22, 2016. Wife started car in school parking lot and headed to the exit. While making a left hand turn onto the main road, and accelerating, loud noises again heard under the car and it lost power even while giving it gas. Had to pull over to the side of the road. Shut off car and re-started. No issues. Wife refuses to drive the car until fixed. Taken to dealer on July 29, 2016. Unable to duplicate. Returning to dealer Aug 5 for computer re-flash. This is a significant safety issue that is being reported all over the Ford Flex forums and it appears Ford Motor Company will not address the issue.

While leaving a parking lot and accelerating to barely 10 mph, the left front brakes seemed to lock up and the car stuttered. After stopping and accelerating again, the problem did not reoccur at that time. The second time, I was leaving my driveway, again going no more that 10 mph and the same thing happened, this time I noticed my traction control light flashing. I put the car into reverse, backed up a bit thinking I'd run over something, and accelerated again. Nope, didn't run over anything, just traction control seizing up. Very concerned this may happen at higher speeds and cause an accident.

My 2009 Ford Flex limited fwd has less than 50K miles and the rear rotors has been replaced twice. They rusted away, corrosive brake fluid causes rust. My dealer keeps saying that all Flex vehicles have this problem.

I purchased a 2009 Ford Flex from mike dorian Ford that had 14000 miles on it. Two days after purchase I took it to a dealer for a bad grinding sound in the brakes. They performed a tsb on the front brakes. I took it back several more times for braking issues. Then the car came to a grinding stop in traffic several time and I almost got hit. I took it to 2 different dealers complaining about the violent shaking and the inability for it to go when I gave it gas. Finally after this happened several time I was hit as the transmission brought the car to a halt. I suffered injuries and the car had $15000 worth of damages. The person who hit me sued my insurance company. The dealership had my car for four months and never looked at the back brakes or transmission. I took it back 6 times for a leaking transmission and several other issues that were not fixed. This vehicle continues to come to a stop after trying to go from a dead stop. I almost got hit by a semi truck. My wife will not ride in the car because she feels we will die in this car. Ford has done nothing about this problem. I talked to a Ford mechanic who told me it was a transmission problem yet Ford has never even looked at the transmission. I feel I am going to be killed in this car. After $15000 of damages I have lost all value to the vehicle and my insurance has been raised. I later found out there is a tsb for the transmission yet Ford has never even looked at it.

Purchased Flex in 2009, day 1, 5 miles, station wagon has vibration. To this day, still has vibration. 58000 miles now. Bbbautoline says it's out of coverage for arbitration. Flex was in shop min 12X for same issue. Dealer and engineers said bad brakes, the have put on 5 sets of pads and rotors. Bad wheels, mine were the 17" style, now I have 19" limited wheels, very expensive tires. Still vibrates.... one 3 day service stop at varsity Ford, a@$$$×$@ tech or mechanic drove miles to the tune of 750!!!!! and I wasn't supposed to be upset.....test driving it..... ok, 12,000 miles, on new 19" hankook junk tires, optimo, they were bald, dealer says I have to replace myself, a 60,000 mile tire, lol on me. 31000 mi, dealer says don't bring back, we can't fix.... and said it's a lemon, go arbitrate it out, we know it's a bad car, but we can't get you a new one. 35,000 miles, spouse taking kids to daycare, turns corner, says she heard something pop, and she could not steer, hit a parked car.... after looking with police, I have video and photo proof, inner tie-rod snapped, causing the accident. So, 4,000$ of damage to my car, from a tie rod not being installed right. There was an inch of play, up and down, side to side, on the outer tie rod, from not being installed correctly at the factory, hmmmmmm, made in Canada. So now, after accident, car fixed, I thought for sure, it would be a whole new driving vehicle? shat not! 58,000 now, and vibrating like an off balance washing machine. And BBB and Ford are not taking any responsibility. All I wish was for a Flex that drove smoothly.....

Drove 30 miles at highway speed. Then in shopping mall engine quit suddenly at 20 mph without any warning. No power brakes, no power steering. It was if someone had turned off the ignition. I was able to muscle the car out of traffic and was thankful this sudden failure did not occur at speed or while making a turn across traffic. This seems to be a problem identical to those reported by other 09 Flex owners, but Ford ( or at least my local dealer) is not interested in addressing the problem. Considering that the car had a loss of control, it is puzzling that this defect is not being taken more seriously. In terms of severity of the problem, this sounds like a '10'. the proposed fix is new throttle body, reprogram computer, clean injectors. Since no fault codes appeared and since this is intermittent, the mechanical breakdown policy does not cover what is clearly a manufacturing defect on these early builds. So the problem is twofold: The car dies suddenly and the computer does not recognize this as a fault.

Flex 6-cyl

  • 34,500 miles
Took car to tire merchant to replace tires. They reported to me a problem with right rear brake. Piston is fully retracted out, and brake pads have abnormal wear relative to others on car. Suggested that I contact dealer for replacement of brake caliper. Also reported that they contacted Napa, and were told that Napa had received many reports of right rear brake caliper issues on 2009 Flex, and in fact, Napa has part on indefinite back order. Part also on back order at Ford (only for right rear brake, apparently defect isolated to this brake), although placed order for part today. Told that there was no recall although there was a service bulletin so I would be responsible for all costs of replacing defective part since my car recently went out of warranty.
