Recall has not been remedied, and it has been over six months.I was told it would be remedied by june or ford would be held accountable for compensating for repairs on the.Recall. #25SA9/25v695 The recall addresses the camera for backing up witch is still not functioning in a safety risk.
Wile driving 40 mph, the right rear tire locked up and I had to counter steer aggressively to avoid spinning out and hitting oncoming traffic. The car was flat bed delivered to Ford and they recommended the following repairs. "Control Arm- Rear: rear suspension lateral links. The rear upper and lower control arms not only provide suspension travel but also secure the rear end to the vehicle." "*Tires - 4: passenger rear inner sidewall damaged."
An antifreeze leak is very hard to locate because Ford’s design placed the water pump INside the engine rather than on the OUTside, which would be more the norm. If antifreeze leaks enough, it gets into the oil and the entire engine stands to be destroyed. Our heater quit blowing warm air recently and after intently searching we discovered that we had an antifreeze leak inside of our engine, and antifreeze was slowly leaking out through a weephole in the engine. The water pump had gone bad and needed replacing. The hours required to replace this water pump are intense and they are long. Almost the entire engine needs to be dismantled in order to perform the work. Not only does the pump need changed, but so does the timing chain, hoses, seals, gaskets, tensioners and other engine parts, all at the same time, making this a VERY costly out-of-pocket expense for us elderly people who have long relied on Ford’s standard of doing what’s right by its people. In our research we found that the water pumps in Flex engines are failing, regularly, once the vehicle is close to having 80,000 miles on it. This repair most DEFINITELY should be covered by recall since it is happening so regularly. We have just been forced to pay for this repair on our own and I would like to please ask for your help in recovering what we’ve had to spend. Will you please provide contact information as to where we can reach out for assistance in this matter? Your help is VERY much appreciated! Thank you!

Have been waiting for several months for Ford to remedy BOTH recalls. There obviously is no important reason for them to be productive and do the right thing so this issue will likely never be resolved unless I take action and file a complaint. The two issues are not even that critical so I further don't see why action has not been taken. 1. Interior A pillars separating. 2. Back up camera screen on infotainment center.

Recently, while driving on the freeway The drivers B pillar, came off and was only held on by the wires for the keyless entry. While driving on the freeway, I had to hold the B pillar until I could get off the freeway. When I called Ford, they told me to bring it in to get it looked at to proceed with the repair, but was then informed there is no parts at this time and had no time line when they would receive them. which is completely unacceptable since my B pillar is no longer attached. Also, my backup camera does not work. Sometimes it will work, but everything’s upside down and other times it just cuts out with lines across the screen.
