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.

The contact owns a 2011 Ford F-150. While starting the vehicle, the contact heard a grinding noise coming from the engine. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 84,000.

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.

- Toledo, OH, USA

2011 3.5 ecoboost with 50,000 miles would lose power when passing and pulling into traffic due to cam timing chain defect and engine ended up blowing up. $5,640 repair at 54,000 miles and still no recall on this common problem with this engine.

- Capac, MI, USA

Coolant leaks at multiple points where O-rings are located.

- Claremore, OK, USA

Water pump failed

- Claremore, OK, USA

5.0 engine started knocking at 130K miles. Timing chains are also stretched causing another ticking sound.

- Claremore, OK, USA

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

- Wood Village, OR, USA

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

- Keithsburg, IL, USA

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.

The truck is making a severe rattling noise upon start up, which caused check engine light to come one. Codes are saying its timing chain related. Truck will loose power while driving, you can't push accelerator down without it stalling out or without it missing real bad and jerking. Had truck worked on previously by Ford dealer for the missing and acceleration issues. Dealer said it was a coil pack and changed it out and plugs and wires. Here I am within 10,000 miles later and its worst than ever. There is something seriously wrong with these ecoboost engines and timing chain issues. Absolutely no reason that a $40,000+ vehicle can't make it past 70,000 miles without having timing chain issues! extremely disappointed in Ford and the way they are handling this issue. Zero assistance or help. Next step after this official complaint will be a law suit.

- Paducah, KY, USA

I was driving home from the store when the check engine light came on so I connected a code reader and pulled a P0016. Crankshaft/camshaft correlation sensor. I took the truck to a mechanic to find out what can cause this code. After checking out the engine they found that the primary timing chain is stretched causing the play in the engine. This play causes the crankshaft and camshaft timing to be off enough to cause this engine code. This truck has 55000 miles on it and in no way should be having timing chain issues this soon. Clearly Ford has a problem with this timing chain and I should not have to spend $3,500 to have this fixed. This is a growing problem for folks who have these trucks and needs to offer a solution before someone gets hurt.

Misfire at high speeds. Causing engine shake and unable to accelerate. Due to this problem it is a huge risk of being rear ended because of speed drop. Huge safety concern. Spark plug and coil change only helps for a month at a time. This is in the ecoboost model

- Bellevue, NE, USA

While trying to accelerate at higher speeds the vehicle shakes and appears to misfire. When this happens the vehicle struggles to accelerate and black smoke appears from the exhaust. This occurs mostly while trying to pass another vehicle. The check engine light appeared in the beginning and the code referenced a problem with one of the ignition coils which was subsequently changed but the problem still existed without any codes appearing.

The contact owns a 2011 Ford F-150. While stationary, the vehicle would not start when prompted on several occasions. Palm coast Ford in palm coast, Florida was made aware of the failure and replaced the battery, but the failure recurred. The manufacturer was aware of the failure and stated that there were no recalls. The failure mileage was 68,000.

- Palm Coast, FL, USA

Going around 70mph on route 95, truck suddenly shifts from 6th gear down to 1st on it's own, rear wheels locked up and I skidded nearly off the road. Luckily I had my seat belt on or I would have been thrown into the windshield it was so jolting. Came to a stop, no dash lights or engine indicators came on. Turned the truck off, waited about 5 minutes, turned the truck back on, no check engine light, everything seemed ok, slowly drove the next 2 miles to my office. Checking Ford's website, there appears to be a safety recall for this issue. The molded lead frame is the issue, causing random downshifts.

- Woodbridge, VA, USA

My vehicle downshifts into 1st gear at all times but specifically when traveling about 70 mph, it has caused me to almost get ran into on the highway and almost seems you lose control for a bit, its been doing this for 2 1/2 years and is getting worse, I saw Ford had a recall on this type of thing but they said it wasn't in my batch of trucks, I think my batch should also be investigated because my truck is doing exactly that
