general problems of the 2015 Ford F-150 - part 2

I was driving at around 45mph and my truck suddenly downshifted automatically and almost brought me to a complete stop. It finally shifted back up and I was able to return to the proper speed. If this would have happened at higher speeds I could have been in an accident. Event at 45mph, had I not had my seatbelt on it would have thrown me into the steering wheel.

I have had the gasket for the oil pan fix two times. It is leaking again and told by Ford that it will happen again. It is 1200 to have it fixed plus they have to keep it for a few days to make sure the seal is dry. If you do not check the oil all the time it could be low and lock up. I know other people that have had this problem. It is on the 2. 7 eco boost.

Broken exhaust bolt on passenger manifold. Exhaust leak. . . Felt as though carbon monoxide gas was entering cabin portion of truck. Smelling of exhaust in cabin of vehicle. Made wife and kids nauseated and lightheaded. Did research and found out that Ford had a poorly designed manifolds and didn't utilize all exhaust bolts. In turn caused the #8 bolt to snap and manifold to warp and release exhaust fumes.

This happened a few years ago and then a few months ago and then a few weeks ago on 11/10 and 11/12. It took two dealers to work on problem. There are no engine codes to point to problem. In the shop now. Apparently, it is the vct solenoid. A known safety problem. . Read more...

I bought the vehicle 3 to four weeks ago. For about a total of 6 or 7 times since I purchased the vehicle, the vehicle unexplainably goes into limp mode for no apparent reason. The engine is idling but will not accelerate at all, which in my case was extremely dangerous. In one instance, I was going up a mountain pass in an area that is steep with many sharp turns creating a blind turn issue. The truck suddenly went into limp mode just on the other side of a sharp turn. Vehicles behind me had absolutely no warning that I was stopped in the middle of the road. A second time, I was accelerating into heavy traffic when it occurred. This created all sorts of havoc as I tried to warn other drivers that I was disabled. This is critical and needs to be investigated.

During the course of driving on the interstate at 70mph the vehicle decelerated and went to a lower gear. The dash panel of the truck did not show all of the gears available. An emergency stop on the side of the road and turning the vehicle off and back on temporarily resolved the issue. It occurred intermittently and without warning. The truck continued to show problems and was taken to a transmissions shop which checked the transmission, replaced a line for a small leak and said everything seemed to be in order. The cause was not found to be a lack of transmission fluid as the levels were normal. The truck continued to intermittently decelerate. The last time that occurred, the back wheels locked up while on the road. The truck is now sitting due to the safety risk it poses and the locked up transmission on the rear end. It is available for inspection upon request. My safety and that of others was at risk. The problem was not replicated in a service center. The vehicle was inspected beforehand but not after the last issue, (it needs a tow as the back wheels are frozen). There was a warning light for the engine camshaft that came on and the problem was diagnosed at Ford as a camshaft issue though they could not understand the deceleration issue. The truck was taken first to Ford then to an independent transmission shop. Due to the issue the truck is not in use.

Driving down the hyw the 2015 f150 will shut down to limp mode can not excelarate lose of power have to stop and restart did this 4 times. As this happen I was just about rear-ended.

Started truck and drove about 1/4 mile when it lost all power and numerous messages started flashing on the screen. Truck had no power and I had to pull to the side of the blvd to let other traffic pass. Shut engine off and restarted. Started oksy but returned home. Learned from my mechanic 180 miles away that it is the throttle body, a common problem to which there is no recall but possibly and extended warranty. Truck has 49,253 miles on it.

Transmission changing gears on its own while driy.

The timing belt/chain is failing on F-150 trucks and multiple people have sent in issues. I think from 2015-2018. It looks like you are already looking at other Fords with same issue. What I was told is that there could be sudden stalling: if the timing is thrown off or the chain snaps, the engine cuts out instantly. Losing power steering and engine power while driving in traffic creates an immediate crash hazard. Severe misfires and power loss: a slipping chain causes rough idling, violent shaking, and an inability to accelerate which happened to the truck. Due to this I had to get mine fixed in June of 2024 I have attached the invoices. I tried to upload invoice but said there was an error.

My 2015 Ford F-150 truck has had multiple issues related to performance issues, with only 80,000 miles on it. I have had issues with it losing power while driving, both with and without towing a trailer where it just powers down on the highway from 70-75 mph down to 40-50 mph in traffic. I usually just have to pull over, turn the engine off and then turn it back on and everything runs normal. It is currently at phil long Ford in colorado springs, CO, having the short block and driver side cylinder head replaced at 80,000 miles because it was smoking out the exhaust and they determined that it had coolant leaking into the #4 and #5 cylinders. This is after it had a completely new engine installed at 75,000 miles due to coolant leaking into the 3# cylinder and causing severe damage to the engine. It was in the repair shop from August 2023 until late December 2023 because the engines were are backorder. The passenger side cylinder heads are currently on a 13 month backorder according to the dealership, which is why they are only replacing the short block and driver side cylinder head this time, after only 5,000 miles on the replacement engine. I have also received multiple recall notifications regarding this vehicle, the most recent of which was on 4/22/2024 for #24e03 powertrain control module software update, none of which have been repaired during the multiple times and extended durations that my vehicle was at the Ford dealership for repairs. Two recalls existed and should have been repaired when my vehicle was at the dealership between August and December of 2023, and the most recent recall shows "no remedy available" for a pcm module software update?.

When I was driving a light came on that said low oil pressure. I checked the oil, and it was full. Driving to get it checked out the engine stopped. I had it towed to the Ford dealership. The engine failed at 81,000 on my 2015 Ford F-150. I was charged $220 for the Ford technicians to say "they do not know why the engine failed but for $16,000 they will put a new engine in. " I asked for details as there is low miles on the engine. The technician said "they would be happy to tear apart the engine, for a fee, to find out. " I asked about a warranty they said the motor is good for 60,000 miles after which point it is not covered. I found, on the internet, that the 2015 2. 7 ecoboost engine has problems with oil leaks and that the piston melt, fuse together and the engine stops. I also found there is a federal investigation into the 2. 7 ecoboost engine. . Read more...

This engine defect is well known to Ford ; it involves the 2015-2017 2. 7 liter ecobost . These engines were produced with a faulty oil pan gasket . I just paid to replace the third oil pan . Taken in totality these leaking oil pans are a safety issue since oil is deposited on our roads leading to slick conditions and deteriorating road surfaces . Ford's most recent TSB related to this defect is TSB 24-2098 , which superceds tsb23-2330 . This defect effects thousands of Ford's 2. 7 liter ecoboost engines . Please examine this safety issue . Thank you.

The oil gaskets on the valve covers and oil pan are defective and leak. This causes oil to be leaked on the engine and can catch fire. Ford has stopped making the defective parts and now charging customers for the repair. If the repairs are not made, the engine fire is a probability.

The truck only goes through 1 through 3 and then when it shifts into 4 it doesn’t go anywhere and it throws a bunch of service codes that just go away when you turn the truck off it has dropped from 6th gear to 3rd and locked the tires up and spun me out almost causing me to wreck the truck.
