The truck looses power while driving down the road. Most of the time I have been driving as a slow rate of speed 20-35 mph. The engine continues to run and the wrench light comes on the dash. The transmission receives no power and the truck will only coast forward. Immediate solution is to pull over, shut the engine off and restart. The truck then has power. The problem may repeat itself within miles or it may not repeat for days/weeks. This happen 18 months ago, 4 months ago, and 2 days ago.

Had complete brake failure. Was able to get the truck stopped. Saw it was 2 pints low on fluid. Added fluid, drove towards my auto shop, had to stop to fill the brake fluid again (the light went on this time). Did this a few times. Just before I got to the stop, the truck blew out some smoke, chugged, and the motor seized up. Towed the truck to the shop, they found out the master cylinder leaked and the vacuum lines sucked the brake fluid out of the master cylinder and dumped it into the cylinders in the motor and this blew my motor. I hear there is a recall for this on 2014 F-150S but not on the 2011. Terrible design. A brake problem should not blow up my motor.

My truck is having the issues outlined in the NHTSA investgation PE13018. In some cases in rainy or humid conditions the engine misfires (sometimes without any codes) and loses power when accelerating. The engine sometimes than won't shift out of a lower gear until it is shut off and restarted. The Ford tsb (12-10-19) and related Q&a provided to the NHTSA has a fix but because the dealership has not repeated the issues (it hasn't been humid out and they aren't doing it under highway or open throttle speeds). We have given dates, experiences and codes to the dealership (including ones in the tsb). But as they can't recreate it in the service bay, they won't make the fix.

The contact owns a 2011 Ford F-150. While driving approximately 10 mph, the contact heard a loud bang sound from the engine compartment. The contact pulled the vehicle over to the side of the road to find that coolant was leaking onto the ground. The vehicle was towed to an independent mechanic and it was determined that the coolant was leaking into the oil and there were also metal shavings in the mixture. The dealer and manufacturer were not notified of the failure. The vehicle was not repaired. The approximate failure mileage was 94,000.

Driving 70 mph when 2011 Ford F-150 while driving in cruise control with A/C on lost all power..........and a tool displayed on dash. I was able to pull over on-side of interstate luckily.......turned off vehicle waited a few minutes and re-started with no further issues. I'm concerned this is similar to other issues Ford products have been having. Need answers before your vehicle hurts my family!!!

When coming to a stoplight on a city street, brakes were applied but the engine raced to a high RPM. Next I pushed pedal harder but rear tires were now spinning on dry pavement. I put F-150 truck into park stopping inches from the car stopped ahead of me at stoplight.

If I start my truck and immediately put it in reverse my brakes will not work, I have to let the truck sit for a couple minutes before my brakes will work. I have replaced my brakes thinking this would correct the problem but it did not. I have backed into a concrete post because of this. Very unsafe

Truck has a timing chain rattle and has had the same rattle for 28,000 miles, since I've owned the truck. It only happens when the truck has been sitting for an extended period. The rattle lasts from 2-10 seconds. I have videos of it happening in my driveway, after a cold start. Dealer refuses to fix it because it doesn't happen after I drive it to them and they start it. Tsb-14-0194, tsb 16-0027, tsb- 15-0131. All 3 tsbs have the same results. I have shown the dealer my videos nd the service advisor told me "no problem we can get it fixed", only to find out he dealer refuses to fix it until they can get the truck to do it for them, under their care. The tsb states that if the owner hears the rattle the dealer is to fix it.

Truck makes a loud rattling noise upon starting cold in the morning. Noise lasts for 3-5 seconds, than goes away. The electric vacuum pump was recalled and replaced roughly a year and a half ago. I took truck to Ford dealership last fall (2017), and they stated it was the tension belt/pulley loosening. While doing some research online, seems like quite a few Ford truck owners with that ecoboost engine are having same issue all across the country in all different climates. This seems like a safety issue to me, and was hoping Ford would recall and take care of this. Truck seems to make this noise while stationary upon starting first thing in the morning. I contacted Ford corporate, and they recommended filing a claim with you guys.

My timing chain stretched at 48 thousand miles. Ford needs to do a re-call on this. It is not ok that the consumer has to pay for a faulty product. Long time Ford owner and this needs to be fixed

The morning after I bought my truck in November. I went too start it on a cold morning and noticed a rattling noise coming from engine. Only does it when engine is cold. I've been told it is my timing chain. And the dealer wouldn't fix it since there was no warranty

At 10K blowing black smoke, lose power when passing at 10K also, check engine light at 40K. Dealer found nothing wrong and cleared code and check engine light went off. At 54 K engine ran rough and wanted to stall, began to make noise. Towed to dealer. Timing chains went bad and bent valves. Dealer said 10,000 dollars for new engine. I talked to Ford and they said nothing could be done. Dealer said to call them again. They said nothing can be done again. Next day dealer called and said they would do the engine for $5643 dollars. The truck only has 54,000 miles!

The contact owns a 2011 Ford F-150. While attempting to accelerate up hill, the vehicle shook violently and the rpms decreased. The contact took the vehicle to triple J Ford (470 marine corps drive, tamuning, guam 96913, 671-648-2277) where it was diagnosed that the catalytic converter failed and needed to be replaced. The vehicle was repaired, but the failure recurred. The contact returned the vehicle to the same dealer and was informed that there was no failure due to no failure diagnostic codes. When test driving the vehicle, the failure recurred at approximately 1,500 rpms. The vehicle received a replacement of the coil packs, spark plugs, O2 sensors, and an injector cleaning. On approximately August 5, 2017, the failure recurred after the second set of repairs were made. The vehicle was returned to the dealer where it was diagnosed that the turbo needed to be replaced. The vehicle was repaired. The turbo boost for the vehicle failed. The vehicle was returned to the dealer where it was diagnosed that the vacuum pipe was fractured and needed to be replaced. The vehicle was repaired; however, the failure recurred and the instrument panel showed that the tachometer was fluctuating. The vehicle was returned to the dealer where it was diagnosed that the injector needed to be replaced. Three injectors were replaced; however, the failure recurred. The manufacturer was made aware of the failures and was helping to get the failures resolved. The approximate failure mileage was 56,000.
