I've been having problems with my truck since my purchase date June 29 of 2021! I own a 2011 Ford F150 super crew! My truck has been to the ford company at least 5 to 6 times. I have inform the service team that this is a business truck! I have bought a new battery because I was told I was having low voltage but with the new battery I am having the same issues! I have had actually weighed a problem her assembly problems I have had my brakes replaced in the rear I have had converter problems and I was also told that I should get a tuneup but didn't need it! I have had some bad experience with my Ford F150 2011 super crew and all I ask is for a better experience! I've never had an accident in his truck! I never had a accident in this truck!!!! I have had so many problems with the truck!
I was driving 65MPH. The Change Oil Soon Message come on. I pressed Reset to clear the message. Within seconds the truck jerked twice and when I looked at the dash I was in 1st gear doing over 5500 RPM. The speedometer showed I was not moving but no other indications of error on the dash. No Wrench showing this time. I pulled over and turned the truck off. Restarted the engine and everything was just fine the whole way home from there. I drove the truck to the dealership (Lawton, OK) to check the truck for me on Thursday but they seemed to think if the check engine light was not on there was no urgency. They know it is an F150 from 2011. They want me to return on the 16th for an appointment.
On certain days, usually humid days, when you approach a hill and give it gas, a wrench appears on the display and the truck goes into Limp mode. It may go for weeks without doing this, but when it happens, you may get killed. Especially, if you are on a highway. You have no power to move the truck. You are a sitting duck. I took in to a service station and the cleaned the Throttle body, but it still happens. If you drive slowly without changing accelerator position the truck will drive but too slowly. It happens far too much.
Was starting to accelerate out of a toll booth a vehicle and was about 60mph when suddenly the engine shut off. Electrical worked. Got mechanical symbol and then oil pressure low warning. It started to down shift and slow rapidly in traffic. Managed to get to side of road but almost got hit. Got it towed to dealer and the fuel pump fuse had melted. Shutting off the fuel pump.
The vacuum pump recall was replaced in 2016 and it's bad again. I have the emissions warranty with ford I am 6 owner the other 5 owners were resale so I get the one time lifetime emission warranty. the truck is doing all kinds of crazy stuff
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,[redacted] 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. …
Truck will have severe intermittent stumble/misfiring on acceleration from 45mph+ in humid, wet or damp conditions. The vehicle shudders violently, bogs down, and check engine light flashes eventually becoming a solid engine light. This involves the engine shuddering when there is acceleration at highway speeds; this is very dangerous when trying to pass vehicles at highway speeds. Have my spark plugs and coils replaced after the following happened in damp and wet weather conditions. Make years seem to involve 2011-14 EcoBoost trucks. From thousands of Ford forum posts, the trucks have an intercooler condensation problem that is causing poor performance and spark plugs/coils to fail early. Water and oil vapor/residue condensation is being sucked into the engine. …
I have several occasion for the past couple of years of my f150 not starting when turning the key on. I have taken it to the Ford dealership several times but they couldn't determine the problem. I've had several occasion of the low oil pressure light turn on and the vehicle has stalled. Just recently I was making a right turn and at a small angle and the truck completely stalled out while driving. I had to coast to a stop without any power steering until it finally stopped. I tried to crank it over but it wouldn't start. After about 5 minutes it finally started without issue. I've had it stall twice while I lost total control of my truck and it is extremely dangerous. I had to tow it to my dealership again today. I think I May have finally found the issue which May point to a faulty 20amp fuel pump fuse. …
Upon downshift during acceleration, the truck shudders, misfires, backfires through exhaust system, and loses power while creating a violent shake in the drivetrain. This occurs in below 35 dry or wet weather. This issue destroyed my catalytic converters, as well as broke loose the baffles in factory muffler causing over $2,000 in repairs for exhaust. I further replaced plugs, and plug boots. The vehicle continues to have this severe issue, and the only way to keep from further damaging the vehicle is to pull off the road, and idle as well as rev engine for several minutes. It is extremely unsafe, and nearly caused other vehicles to rear ended me on at least 5 occasions. All of which I had to jump onto shoulder of road or in median to keep from getting hit. My research shows that this is a common problem amongst owners of this vehicle. …
