2011 Ford Flex Warren, RI

POWER TRAIN

Went to put car in reverse and it kept driving forward- no weird sound or anything. Proceeded to put the car in park and it was still moving forward. Transmission was stuck on drive.The shifter is disconnected from the transmission with no warning .Just looked and the transmission shifter bushing is disconnected. Also saw that this part is a recall on other ford vehicles. Had this been recalled on all vehicles with this part, I would have known to have it fixed. Luckily I was somewhere safe when this happened but it would have put myself as well as others in danger.

2011 Ford Flex Battle Creek, MI

POWER TRAIN

My brakes locked up suddenly on the rear end causing me to get stuck in the middle of the road and unable to move it, even to tow it. I had to take 2 days almost to fix it in the middle of the road, since yesterday morning. They also began locking up suddenly on the front end, the wheel bearing, CV Joint, Tie Rods, CV Axles, CV Boots, and sway bars began failing out of nowhere as well. The brakes may or may not be able to be replicated, as they are partially fixed and yes my entire front end can be replicated. The danger is my brakes locked up as I was driving, in the middle of the road at that. I have not been able to get the front end fixed as it is expensive, however the danger of this is the tires falling off or the front end failing all together. ALL of the other people who drive these that I have talked to and met have had the same problem and yes they are factory parts! Even the people who have only 30 to 60000 miles on their 2011 Ford Flex Titaniums have these issues! Not only this but also the sensors go bad almost immediately off the lot, which can cause the car to brake without warning, stop running out of nowhere, make the power steering module fail, make your vehicle stutter because ALL of the sensors are bad. These vehicles need to be recalled and fixed, or recalled and replaced with better vehicles (from $60,000 up to $95,000) with any mileage any year. Please recall these and please help! I just got mine, this isn't right!

2014 Ford Flex Sioux Falls, SD

POWER TRAIN

2014 Ford Flex AWD with 122,032 miles. Tried to get on interstate and when I got to 55mph heard a loud bang and smoke rolling from underneath car. Pulled over to find that the front differential had blown it's seals and gear lube sprayed everywhere. Car has been gently driven 25,000 in last 4 years with only other issues. Rear Hatch drive motor. Blend door actuators and strut mounts. Which all happened at 110,254 miles. Great car but now $3100 for a major part defect that is from Ford itself. Maintenance schedule in owners manual says an I quote. "Do not add fluid or change no need to check guaranteed for life" why is it there is the same recall for it but my vin is not included. Makes no sense. Been regularly maintained even before intervals. No warning no sign. Just boom

2016 Ford Flex Toledo, OH

POWER TRAIN

The power transfer unit otherwise referred to as a transfer case exploded from the inside with under 50k miles on the Flex resulting in the transmission cracking and breaking as well. AAA inspected and replaced both transmission and transfer case. They say they see a lot of them for these models and is a common issue. We kept old transfer case as proof. Car is not used for towing as it has no hitch and as stated before had under 50000 miles when it destroyed itself with myself and kids in the car driving 45 mph.

AWD indicator states off while driving at times without warning. Also leaking sludge. Now need to replace PTU and FORD AWD vehicles are known for this issue... Needs to be recalled as system can fail and explode.. This is supposed last the lifetime of the vehicle and is not set up for maintenance causing the system to fail. I am replacing with a unit that can be serviced every 30K miles. This is a safety issue.

2011 Ford Flex at 112,000 miles North Street, MI

POWER TRAIN

The contact owns a 2011 Ford Flex. The contact stated that upon her husband starting the vehicle, the vehicle entered limp mode as he exited the driveway. Her husband then drove the vehicle back into the driveway and turned the vehicle off. The next day, her husband started that vehicle and was temporarily able to resume normal driving; however, the vehicle entered limp mode while in traffic as the power train warning light illuminated. Her husband was able to coast the vehicle back home while in limp mode and had the vehicle towed to a dealer. The dealer initially diagnosed the vehicle with a defective throttle body; however, the failure persisted after the part was repaired. The contact made numerous trips back to the dealer; however, the failure persisted after each visit. The contact was then informed to take the vehicle back once the wrench light had illuminated. Once the wrench light illuminated, the contact began to drive the vehicle to the dealer. While driving, she heard an abnormal clunking sound coming from the vehicle as the check engine warning light illuminated and the vehicle entered limp mode. The contact made it to the dealer as antifreeze began leaking from the vehicle. The contact was then informed by the mechanic that the radiator fluid had begun to leak out of the vehicle as a result of the water pump, which was previously replaced. The mechanic also discovered that the radiator fluid had leaked out of the rear main seal of engine which caused engine failure. The manufacturer was notified of the failure and provided the contact with a case number. The vehicle remained at the dealer and was not repaired. The failure mileage was approximately 112,000.
