2010 Ford F-150 5.4 ltr stalling at idle and losing control of vehicle. Repairs done at local dealership including replacement of catalytic converters and O2 sensors. Problem still exists almost causing several accidents. Back at dealership again for review. Truck is dangerous to drive. Same problem can be seen all over the internet. Ford needs to address this issue before someone is killed.

Vehicle stalled as if out of fuel, despite having been recently filled with gas. Fuel monitoring system (tank level gage and range computer) indicated that vehicle was using fuel at much higher rate than normal. For example, normal range of this truck when 36 gallon tank is full is approximately 570 miles. After 250 miles, gauge was showing tank out of fuel and range computer was instructing me to refuel. Refilling only required 15 gallons, indicating reduced tank storage capacity. After performing research via internet, suspected bent fuel pump mount due to failed tank purge valve. Brought vehicle to dealer for service who found stored P-1450 code which indicated a prior failure of the fuel vent purge valve. Dealer dropped the tank, removed the fuel pump assembly and verified that the mounting system for the pump assembly had been severely bent when tank collapsed under atmospheric pressure. Negative gage pressure inside of tank caused plastic fuel tank to collapse, severely bending fuel pump mounting hardware which is constructed of two 3/16" diameter steel rods. Apparently the purge valve failed and either there is no pressure relief system, or it failed. Dealer replaced pump and purge solenoid valve at owner cost of $950+. dealer indicated that there was no liability from either dealer or manufacturer. My concerns is simple....how can the design of the fuel system allow the tank to collapse at all? my case resulted in pump hardware damage, but it seem very plausible that fuel tank damage or failure is very possible, potentially leading to spilled fuel and fire.

I have 2010 Ford F150 FX4. I have 36000 miles on it and am the original. Bought it new from dealership. Today I was towing my horse trailer with 2 horses in it and came through the residential area near the barn. Speed limit is 30 miles an hour and I was doing 25 and was actually braking to slow it down to 20. I heard a weird engine noise and suddenly the truck surged and took off. We hit almost 50 miles an hour in this residential 2 lane road in a matter of seconds and I was standing on the brakes with both feet. My friend in the truck was downshifting (automatic) for me in an attempt to slow engine down. We managed to get it to 2nd and with me standing on brakes we were able to keep it at 40 mph. Neutral had no effect and rpms way too high for first gear-every time I slightly lifted my foot of the brakes slightly, we surged to 50 and the truck kept trying to go faster. Nothing we tried could get it to stop, slow or return to normal. We tried neutral and nothing happened. It was not the floor mat or the tow feature. Did not have speed control on. Scariest ride of my life and with two horses behind me. I was prepared to hit a tree or rock wall as we were running out of road. I was terrified of jack knifing. We finally hit an incline for a hill and we slammed it into neutral again, pulled the emergency brake and shut off the engine when we got to the top. Think my brakes completely burned out and smoke was coming from my engine. Numerous people that we had terrified pulled over with us once we got the runaway truck stopped. Called tow truck and had towed to dealership and will see what they say tomorrow. I shudder to think what could have happened had someone pulled onto the road in front of us or a deer stepped out. I am terrified of this truck now.

I was coming to a complete stop at a red light and oil light illuminated and made audible beep and engine shut down. Placed truck in park and restarted right up placed into drive and drove away without issue when light turned green. This is the third time this has happened always in the same way in same order complete stop oil light beep and engine shut down. The first time it happened it was brought to dealer and since no engine light was not on and no stored codes we found I was sent on my way. Sine I owns own scan tools and am now out of warranty I have need to bring to dealer to waste my time when they can't diagnose until there is a recall.

- Cranford, NJ, USA

Truck stalls intermittently. Usually it is while coming to a stop but occasionally it is while making a slow turn. This means the power steering goes as do the brakes. Very scary. The engine codes have been checked and since they do not show anything the truck is considered good. Yet it continues to stall.

- Dunedin, FL, USA

While decelerating 2010 Ford F150 stalled (4.6L V-8). Vehicle restarted in neutral, then stalled each time vehicle was put in gear. Increased rpms in neutral and put vehicle in drive and drove to safe area, vehicle stalled. Cleaned mass air flow and made it home. Took vehicle to local dealership where vehicle was purchased and was told that because the onboard computer is not displaying a code that the truck cannot be fixed. Currently I refuse to drive a vehicle that is stalling unexpectedly and subsequently losing power steering and brake assist. This vehicle is a danger and liability to any driving inside it, or near it.

My 2010 Ford F 150 that I bought new in August of 2010 has stalled five different time over the last two years. The first time was about a month after I bought it with less than 2000 miles on it. While stopping at a red light the engine just died. The other four times was while making a left turn. When it stalls the engine RPM just goes down smoothly to zero and becomes very hard to steer and brake. This is very dangerous while making a turn across oncoming traffic which is how two of the stalls happened. The last incident happened on 11/27/2012 with only 21,000 miles on my truck. I came extremely close to hitting a dump trunk that had to swerve not to hit me. After I stop and put it back to park it starts right back up and runs fine. No engine lights and the dealer says there are no codes set. I have taken it in twice before with no help. This is an extremely dangerous safety issue that needs to be fixed. Updated 03/26/14

While breaking to make right hand turn engine stalled. First indication was truck was impossible to steer. I was able to stop truck in the middle of the intersection. At a higher speed this would have been deadly. Ford dealer claimed to have never heard of the problem even though an internet search shows thousands of such incidents, many of them reported to this Agency. Dealer was unable to find a cause, although the manager said it was likely the throttle body but he could not replace a part under warranty unless it was positively known to be defective. I was sent on my way to risk my life in an unsafe vehicle.

- Crystal Lake, IL, USA

Vehicle engine has stopped while in motion on two separate occasions. On 5 Oct 2012 while merging into traffic at about 45 mphs and once on 19 Oct 2012 while coming to a stop at a red light. Was unable to restart at stop light for about 2 minutes. Very dangerous problem because I lost control of all power steering and braking. Brought it to the dealership who stated that this is a common problem among my make and year model. Dealership replaced the fuel vapor valve assembly. Remains to be seen as to whether the problem is fixed or not. Of course, the problem is not covered under the extended warranty.

- West Monroe, LA, USA

When making a left turn into oncoming traffic, the engine died which disabled the power brakes and power steering. After coming to a stop, I was able to start the engine and continue driving. I took the truck to the Ford dealer and they checked the computer codes and said nothing was wrong. As a side note, nothing is wrong according to them unless the computer finds an error code.

- Port Sulphur, LA, USA

Sometimes around 45 to 50 mph when accelerating, the truck does a violent hard shift. It is random when it will happen and has been happening for over a year. I have taken the truck to two different dealerships several times and they keep telling me Ford is aware of it but does not have a solution. I have contacted Ford directly and they just tell me to take it back to the dealership.

This F-150 pick up truck was purchased in April 2010 as new. Everything was ok until April 2012. The truck stalled without warning when it slowed down or made turns. The engine died and no power, no steering. I was able to restart it and sent the truck to the dealer shop right away. On the way to the dealer, it stalled couple of more times. Luckily, no other cars were behind, otherwise I could not imagine what would happen. The dealer could not duplicate the problem or get a code. I checked online and noticed many 2010 F150 owners had same problems. Some of people mentioned to change throttle body, so I told the dealer shop and got throttle body changed. During the next 2 months, it did not happen again. However, on July 5th 2012, it stalled again when I made turns in the local. I sent the truck back to the dealer shop again and they still did not know how to fix the problem, since it happened intermittent. Now I am afraid of driving my truck. Absolutely no drive on highways. The people have already complained the 2010 model that the trucks stalled on the highway at >65 mph. It is a severe safety issue. I am very frustrated since the truck is not living to what it is suppose to be.

Engine stalls at low speeds causing loss of steering and braking. There was no check engine light or error code when this first occurred. After the engine had stalled for about 32-35 times, the check engine light finally came on. I took the truck to a local mechanic shop to read the code which indicated that the evap system was blocked. My dealer determined that a solenoid in the fuel evap. System had failed. As a result the fuel tank was collapsed by vacuum because there was no secondary tank vent. This is dangerous! there should be a secondary vent or a pressure/vacuum sensor to prevent the tank from being collapsed. Note: The tank was collapsed so much so, as to damage the pump/level sending unit assembly.

On May 8th 2012, my truck stalled while I was merging into traffic at approx. 55 mph. The vehicle was brand new when I purchased it in may of 2009 from gulf coast auto Ford in angleton, Texas. So, I had them tow it to their shop for repairs. The mass air flow sensor was replaced on May 9th, and I drove the vehicle until Friday, May 11th, when the same problem occurred. The vehicle stalled at traffic speeds, died, and then couldn't be restarted! this second incident also resulted in my having the vehicle towed to the dealership where I am told that they can't find the problem!! it now starts after the stalling, but not until a period of hours passes. What can I do" this is a serious safety issue" Ford is telling the dealership to put an on-board data recorder on my truck that they cannot even get from Ford! I only have 52000 miles on this vehicle and have cared for it meticulously.
