Ford F150 2011 ecoboost engine. In 2015, truck started to loose power going up hills or carrying a load in truck bed. Then the truck went into limp mode on highway going 70 mph. So in January 2015, Ford replaced timing chain at 60,000 miles. Now two years later and 40K miles since - truck is having timing chain errors again. Engine looses power and engine light and codes set saying timing chain errors. Same symptoms as before. Ford says truck is out of warranty and will not fix unless I pay.

Primary timing chain wear. According to tsb. 15-0044, the structure of the timing chain is inferior to the point it stretches. If it breaks, the engine will be compromised and a full re-haul of engines interior will be needed. A loud grinding noise is always heard upon startup in a "cold" start up.several complaints on line concering Ford's below standard of material / cost of any repairs. Also mentioned is after repairs are done, same trouble returns in short period of time after repairs. Unknown the affect the timing chain will have on vehicle if it breaks in transit. Note: As far as I can tell, the issue has started as soon as vehicle purchased reaches "out of warranty" mileage status.

I drive a 2011 platinum with the 3.5 L eco junk when driving on the highway the truck looses all power and shakes and doesn't want to shift up when accelerating hard it will stick in 3rd or 4th gear at 70 mph and when it finally shifts it takes off fast and hard these trucks with the ecoboost are junk and they should just recall the whole truck considering Ford can't figure out how to fix there problems

According to the research I have done to this point the fist recall that I believe applies to this vehicle is tsb 13-6-8, and the 2nd is tsb 13-8-1. both of these symptoms are prevalent to my vehicle but Ford fails to act on this tsb and fails to make the necessary repairs that will remedy these issues. Once again this vehicle is now part of a field service action (15N05) for the electric vacuum pump, and will return the vehicle on 3/24/2017 to see if they will respond in this action, and once again bring these tsb's to there attention as previously done to see if they will repair the vehicle to an acceptable operating standard. If Ford fails to respond to the tsb's and to the field service actions, what are my options to see these repairs take place, and my vehicle is in a safe and proper working function?

It is loosing power when acceleration during wet or cold conditions. This will happen when getting on the freeway, or passing, going up hills and acceleration from a stopped position.

Made a right onto hwy & almost got smashed, no power in the peddle, with a semi coming at me full speed I'm sitting there trying to go, he blew his horn passing me in left lane... crazy!!!!!!! this really should be a recall, not just cuz of me but for the safety of everyone!!! not cool!!! without a doubt this is a safety defect! reduced power during hard acceleration NHTSA preliminary evaluation #PE13018 status: Closed date opened: May 22, 2013 date closed: April 07, 2014 recall: No recall issued component(s): Engine engine and engine cooling summary: On May 22, 2013, the Office Of Defects Investigation (ODI) opened PE13-018 to investigate 95 complaints alleging incidents of reduced engine power during hard accelerations.

Code P0016, timing chain tensioner and timing chain looseness on ecoboost Ford F-150. 2011 w low miles at 59,000. Common problem should be a recall.

- Albany, OR, USA

Tsb 14-0196, tsb 15-0131, tsb 16-0027 - all explain the issue, so yes Ford knows it is a recurring issue. Its basically the engine rattling for 2-5 seconds when you starting the vehicle from a cold start. In mechanics terms the primary timing belt has stretched and takes that 2-5 seconds to pick up the slack.this video explains it very well. Https://www.youtube.com/watch"V=wt3ac_H8wl0 Ford only covers this issue for 5yr/60K miles which is terrible. Tons of different models of Ford have this issue over a variety of different years. This should easily be a recall on Ford or atleast an extension in warranty. This repair will cost around $2000 to have a Ford dealer fix it for you. I currently only have 62K miles on my truck and Ford still won't even give me a discount for the repairs. Im only 2K miles over the warranty mark and still get nothing" I've loved Ford trucks for years but after all this, its easily driving me away from wanting another Ford.

Intercooler for turbo has been replaced twice and will need to be replaced for a third time as the vehicle loses power when accelerating for passing, etc.

My 2011 F150 FX4 has been acting up with the transmission. This has happened multiple times and the dealer is unable to replicate it. So far they have changed all of th coil packs, reset the transmission, changed all the spark plugs in a hope that was the issue. Well it's not. The truck lunges forward with loud bangs and grinding noises. RPM's go up and down and the truck sounds as if I downshifted from 6th gear to first. Then I can only go 40 miles an hour with high rpms. Engine lights have lit up and now a wrench. This is crazy my gauges don't work this is dangerous.

This is the second time I have had this issue with this truck, while merging on a highway, my truck loses all power and starts shaking rapidly, once again I was almost involved in an auto accident because I could not merge. When I initially had this issue 50 thousand miles ago, I brought my truck to auto-nation Ford in white bear lake Minnesota, they said it was an issue of spark plugs, wires and coil packs, Ford also said the issue was the inter-cooler. Ford fixed all of those issues roughly 50 thousand miles ago, but here we are, my truck is at 100, xxx miles and this issue happened again! this is a serious safety issue, I have now been run off the road twice and almost crashed into a lake! when my truck loses all power and starts shaking rapidly, I lose control of the half ton truck. I contacted my local Ford dealership, (auto-nation Ford) in white bear lake, where I bought the truck and they would like me to pay in full for all of these issues, which Ford clearly knows about. I know for a fact I am never buying a Ford again, my safety and the safety of my family has now been compromised on multiple occasions and Ford has not once taking responsibility or offered to fix the issue. I am very disgusted with the way Ford has been handling these safety issues. When you buy a brand new truck and things like this happen, the company should take care of you, but once again, Ford has proved that they do not care about their customers.

The engine misfires and changes to "limp mode" after the engine shudders, shakes and looses power. This has happened twice in the life of this vehicle. Also the steering sticks when turning left.

Just letting you know the stumble issues to these vehicles could be dangerous had it happen a week or so ago while towing. The power was totally gone at full throttle while passing a vehicle. What if I didn't have enough time. I just discovered all this information. As I am typing this my vehicle is in the shop getting the catalytic on the driver side (bank one) replaced and a re-flash, as it threw the P0430 dtc. Again it was a drastic power loss at full throttle, when throttle released regular operation occurred. "you try letting off the throttle while in the middle of a pass, I didn't". and by the way I was a mechanic most of my working days. Just because people don't report it doesn't mean it doesn't exist. In my opinion there are a lot more of them out there with the same problem, just google it and you will see many. Thank you
