2013 Ford Flex engine complaints
Page 2 of 2: complaints 11 to 37 of 37, newest first, as owners wrote them.
My 2013 ford flex has had the same issue as the ford explorer. I purchased the vehicle new from sanderson ford in glendale az and noticed after a hard acceleration with the air conditioning set to recirculate. The dealer stated they could not recreate the issue and I took it back home. Years past and it was taken back again and same thing they could not re-create due to there was no mechanic that could drive it at higher speeds. I included a ford flex forum that explains the issue and shows that it does exist out there. Please add the ford flex to the "recall" fix of these issues. In the federal regulations under 49 cfr 393.83 the exhaust shall not leak / discharge so that it enters a sleeper compartment of a truck tractor. We have the same thing here the exhaust leaks into the compartment of where the driver is at. Https://www.fordflex.net/forums/viewtopic.php?t=17923
Tl* the contact owns a 2013 ford flex. While driving approximately 40 MPH, the vehicle stalled and the wrench warning indicator illuminated. The contact turned off and restarted the vehicle, but the failure recurred. The vehicle was not taken to the dealer or an independent mechanic for diagnostic testing. The manufacturer was not notified of the failure. The vehicle was not repaired. The approximate failure mileage was 78,000.
Driving down the road and out of nowhere my vehicle started stalling as if vehicle had no gas. Gas tank was full and vehicle showed me a wrench sign as I was looking at my dashboard
Failure of engine to start/run due to a faulty fuel pump control module. Current ford safety recall #16s31 (the federal safety agency #16v621) is limited only to ford/lincoln vehicles equipped with the ecoboost turbocharged engine. The faulty component on my normally aspirated engine, fuel pump control module #aa8z-9d370-b, is the same component being replaced on vehicles affected by the #16v621 the federal safety agency safety recall. To avoid engines shutting off at speed or not starting, it appears that the recall will need to be expanded to include normally aspirated engines as well. We were fortunate because our vehicle failed sitting in our driveway, not at 75 MPH on the highway. My wife's concern is what would have happened to her and our four grandchildren if this failure had taken place on the interstate in busy traffic at 75 MPH. Why is the same component that is failing on ecoboost turbocharged engines being covered by ford safety recall #16s31 not being recalled on similar vehicles equipped normally aspirated engines using the identical component? Failure of the component has the same effect of an engine that cuts off at speed or will not start. Your attention to this matter is greatly appreciated. The safety of the owners of these popular ford/lincoln family vehicles is at stake.
There is currently an issue with our ecoboost v6 turbo charger. There is a old drain tube leak that has been identified through ford and is a fire safety issue. This issue has been recalled for the 2014 and 2015 ford flex which is identical parts as our vehicle but never recalled. Would like to see this get recalled before harm is had. This is an ongoing leak that has gotten worse over time.
Tl* the contact owns a 2013 ford flex. While driving 30 MPH, the vehicle would overheat. There were no warning indicators illuminated. The vehicle was taken to an independent mechanic who diagnosed that the water pump needed to be replaced. The vehicle was not repaired. The manufacturer was notified, but was not able to assist. The dealer was not contacted. The failure mileage was 98,000.
Car just dies in the middle of driving and the steering systemlocks up. There has been a known recall for a fuel control module on ford flex, there is also known fuel pump problems with ford makes and models. I have lost power twice. Had at the mechanic last month. Could not get it to die for an entire week in the shop. Now it is dead in a parking lot again.
Tl* the contact owns a 2013 ford flex. While driving approximately 25 MPH, the check engine warning indicator illuminated. The vehicle was taken to evergreen ford lincoln (1500 18th avenue nw, assaquah, wa 98027) where it was diagnosed that the timing belt was stretched. Since the timing belt was directly linked to the water pump, a new engine was recommended. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 60,000. The VIN was unknown.
My ford flex stalls while driving anywhere from 10 MPH (in residential area) to 80 MPH on highway. Electrical is still working the engine shuts off and I lose control of gas/brakes. Three warning signs pop up at the same time: check brake system, collision warning not available, and service advance trac. Once I restart the car, the codes will disappear. The problem was intermittent at first, but now it's occurring more frequently. I'm too scared to drive my car now. Ford isnt being much help. I need help.
Car overheats and coolant leaks.
Tl* the contact owns a 2013 ford flex. The contact stated that the vehicle stalled three times without warning. Additionally, the vehicle would not start. The contact called a local dealer (mcdonald ford, 6790 midland rd, freeland, mi 48623) and was informed that the vehicle was not covered under a recall. The manufacturer was notified of the issue and opened case number: cas13638921. The manufacturer stated that if the vehicle failed, the contact should take it to a local dealer for diagnostic testing. The failure mileage was 75,000.
As I'm driving the check engine light turns on and it slows down my car to two miles per hour once I turn it back off and back on it starts working again but as soon as I drive for a couple of miles or not even a couple of minutes the light comes back on and my car go straight to driving to miles per hour I want to know what could be wrong with this and why is it doing it
Tonight was the second time it happened. While I was driving, thank goodness I was not driving fast and was still on our driveway that the engine just stalled for no reason. I tried restarting the car but it would not start. I had to try starting it many times and after awhile it finally started again.
When I put gas in the gas either fill up or even just a cap off on the gas tank, starting the engin is dificult. It hesitates, when trying to start, and has a rough very rough idle. Accelaration is not a problem once we get going, but it is the initial starting of the vehicle that is a problem.
Ithe interior lights stayed on, door sensors malfunctioned, engine power went off, and alarm would go on intermittantly. These problems happened while the car was moving and when it was parked.
Driving the vehicle on city street, a maintenance indicator lit up on the dash and there was no power (acceleration.) vehicle did not shut off, but the accelerator pedal would no longer operate or rev the engine. Coasted to side of road and turned off. Upon restart vehicle operated normally. Turned around to head home. Pulled out from side street and it happened a second time. This time with a check engine light as well. Had there been traffic coming a severe accident could have occurred. Again, turning off and restarting resolved (temporarily) the issue. In the next 3 miles to get home, it occurred 3 more times. Ford dealership diagnosed it to be a faulty throttle body, parts are back ordered. Ford knows this is an issue and has "covered" some models, but still ignores the danger.
There is a dead spot in the engine when you take off or when you accelerate to pass another vehicle or when you want to get onto the highway.(dead spot aka no response from the gas pedal). I took the vehicle to premier ford lincoln dealer ship in brooklyn ny twice and the said the could not find the problem.
The door front driver side door sensor went bad and tells car that door is ajar. This was replaced under warranty last year. Now yesterday the same thing has happened to the front passenger side door sensor. This was quoted to me at $700. This is ridiculous for a bad door sensor that ford has put bad and faulty sensors on. I feel that I should not be liable for .the ford dealership in town said, "this is a problem with ford flex". This door ajar sensor keeps lights illuminated draining the battery, even though the door is shut. This keeps the lights on when driving, and at night makes it very very hard to see and drive. This will cause an accident due to faulty door sensors.
2013 ford flex model pos, rear passenger door ajar sensor was repaired due to being defective while under warranty around 32000 miles I believe, at roughly 45000 miles the drivers door sensor was starting to fail, it would require 2 shuts to shut off. Battery kept dying, got it tested said good but kept dying, did not think it was a issue with the door, but one night I went out to get something from my truck and what do you know every light in the thing is on. Why? You ask because the drivers door is apparently ajar, but its not. I replaced the battery the morning before I seen the lights issue $200 gone. Contacted ford by email recieved no response, contacted via facebook and they responded that they will try to help, recieved a call the next day nope we wont help you. For a $45000 truck it sure is made of low quality material. I will not be recommending ford to anyone. Worried the airbags wont deploy properly if there is an accident, if the truck thinks the door is open. Not to mention the fact my battery will die anywhere I stop for a few hours.

The first incident occurred april/2014 while my flex was idling in the driveway and shut off and would not start for about six hours. I did nothing to diagnose or troubleshoot, it just started after sitting for that time frame. It did not go to the shop. The second incident occurred june 11, 2014 while I was driving about 5 minutes from my home. The engine shut off while I was traveling about 30 MPH, I coasted to a halt in a traffic lane and it would not start. It would crank, but not turn over just like the first incident. It was towed to a shop where it was determined the fuel pump was not getting power, but before it could be isolated the vehicle started. The tech advised since it started they would not be able to do anything further. I took the vehicle to the battlefield ford dealer and told them the issue. It was due for a recall which would switch out the fuel pump and fuel pump control module and was advised that should fix the problem. The service was performed. On june 26, 2014 my wife got in the vehicle in the morning after it had sat in the driveway all night, and when she hit the start button it took many more cranks than usual for the vehicle to start. As soon as she turned from the driveway it started sputtering and fluttering and the engine shut off down the block from our home. She coasted to a halt, the vehicle did start again and she parked it in our driveway. It would crank and crank but would turn over. I called the dealer and had it towed there, fortunately I have aaa. My vehicle is out of warranty to due to mileage. As it stands now this is a very serious issue. We live in northern va and travel I-95 frequently and if the vehicle would turn off while traveling there it could be tragic. We don't feel safe driving this car anymore and will more than likely trade it once the dealer fiddles with it.
Upon hard acceleration exhaust fumes enter the passenger compartment. Go to http://fordflexforum/topic/596-fumes-in-cabin/page-2 for actual carbon monoxide concentrations test results performed by a fire department.
My vehicle motor quit about a mile from my home and I coasted to the side of the road and tried to restart the motor. The smell of gas became very strong and I got out and could see where a stream of gas had started 50 yards back on the street and a puddle was under the gas tank. I got the heck out of there and called ford road assistance. The vehicle was transported to the ford dealer.the safety recall 13s04 for replacing the fuel pump had been performed about a month ago and 1000 miles ago. The dealer had not install the o ring seal properly. They did it again and say it is good to drive. I am not so sure.
While traveling at 55 MPH, on cruise control, the engine began to knock and then the car lurched forward twice and began to shake pretty bad. I pulled off the road and called the dealership. After holding up the cell phone to the engine, I was told to "turn that engine off now!". The car was towed to the dealership and I was later told there was a catastrophic engine failure due to an cylinder within the internal piston that broke free and put a whole in the engine block, requiring the engine to be replaced. The service manager gave me the mangled cylinder and stated he thought the ball bearings had failed and caused the cylinder to wreak havoc with the engine. After seeing the piece that broke off. I feel that we were very lucky it did not come through into the passenger compartment; it could have caused a serious injury, if it had. Ford has agreed to replace the entire engine under the extended warranty, saying this type of failure only happens "1 in a million". I do not have any confidence that the same type of engine failure would not happen again if the ball bearings and or cylinder are inferior. I have pictures available if needed.
On 7/20/13 I dropped off the flex at the dealer for the timely service and also to have the A/C checked. For about 2 months a terrible odor has been coming from the A/C and after the car was unused for a day, the odor was unbearable when we turned on the car A/C. On 7/22/13 at the end of the work day, the service dept called stating all work was completed, that the A/C was working properly and that there was no A/C problems to repair. When I again informed them about the terrible odor, I was informed that the flex has a problem with mildew in the A/C but that there was absolutely nothing they could do to fix the problem. I did not pick up my car from service and called the service manager to inform him/her of what I was told by the service advisor.the service manager agreed that this was a problem with the ford flex A/C, that ford was aware of this A/C issue as of a year ago, but that there was no solution to the problem. I immediately called ford customer service. I was informed that a regional rep would call me in two days. I said that I could not pick up the car as my daughter suffers from upper respiratory ailments and that I would not pick up the car until the mold and mildew was removed and the problem fixed. I informed them that I needed a car in the meantime to ghetto work, etc. I was told that they could not give me a loaner and that I should get a rental car at my own expense and that there may, or may not, be a possibility of a refund for the rental expense. I am curious if anyone else has had this A/C problem with ford and it was corrected?
