2015 FORD F-150 Engine Problems

Was driving at 50mph on hiway, all the sudden truck has loss of power and engine shut off, coasted down to stop, put truck in par, stared the car and drove another 5 miles and same thing happened again. No warning lite, no error messages was present when shut off happened nor during OBS scan at later time was. When second shut off happened there was a shift down happened. Not sure if the transmission speed sensor has something to do with engine shut off.

While in 6th gear driving on the highway at 70 mph the truck downshifted to 3rd and drastically decelerated. When this happened the instrument display went from having all 6 gear numbers viable to only 1 - 3. It had to be put into Manual Mode and shifted into 6th manually. This happens twice in the same trip.

Truck started making a loud sound from engine compartment on startup after towing camper 150 miles. The sound started to get louder and started to notice exhaust smells in the cabin. I took the truck into dealer to find out that the exhaust manifolds were warped leaking on both sides of engine due to a stud being broken that holds the manifold in place the tech said it sounds like a diesel. The service advisor at the dealership said that it is a "common problem" on the 3.5L twin turbo engine. The cab of the truck fills with the exhaust fumes to the point where the driver gets headaches unless the windows are open. I asked if there was a recall on this problem and they said NO. The same manifolds was used for years on that motor, since then Ford redesigned the manifolds to use extra studs into the...

Each time this has happened, the engine starts and runs normally with all warning messages cleared from dash. Safety Concern: Unexpected loss of power can increase the...

Truck is at 135,000 miles and needs its 3rd oil pan due to faulty engineering. Ford is not covering repairs or offering assistance for previously repaired products. I bought truck certified pre-owned with extended warranty. The oil pan was cracked at that time and needed to be replaced at first service. On average oil pans are lasting less then 70,000 miles. How is this allowed to continue to occur.

Intake manifold actuator fails prematurely. Code P2007 and P2005

Transmission abruptly shifted down from high gear to low gear causing it to lock up at a fast speed. My son hit his chest on steering wheel bc it was so abrupt

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.

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.

I was traveling [XXX] near Liverpool, PA at 60mph, the truck flashed a quick code on the dash and then suddenly downshifted from 6th gear to 1st almost spinning the truck as the rear wheels locked up momentarily. It would not upshift past 3rd gear and had to travel 35 miles home like that. I called my local Ford dealer (Parsons) and they said bring the truck in for diagnostic testing, so I did. Meanwhile I searched the internet to see if others had the issue. Turns out they did, BUT my 2015 with the 6R80 was NOT in the recall notice. Ford said it was the lead frame and needed to be replaced. IF it was a known problem, why not inform owners of these trucks. That said, Ford wanted $1500 to fix it, BUT they did not have the part. So I drove the truck (never with my...

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.

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....

[XXX]: check engine light was on and codes P2196 and P2198 were present. The dealer suspected it was the purge valve, causing the problem so they replaced it and reset the codes. 10/10/24: I brought the truck in to have it looked at due to the check engine light being on again. I was told the lead frame needed to be replaced but was on backorder. The bill to diagnose this was 196.80 and I was told I could still drive it. On [XXX], I had to bring my truck in to be inspected because while I was going about 70 mph it all of a sudden downshifted and jerked me forward like it was going to abruptly stop. The check engine light came on and I had to drive pretty slow to avoid a breakdown on the interstate. Very scary to have this happen in interstate traffic It could...

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.

The exhaust manifold on the 2015 Ford F-150 EcoBoost engine is designed with only eight securing bolts. Owners have reported that this number of bolts is insufficient to adequately secure the manifold, leading to heat-induced warping and subsequent exhaust leaks. The leaks cause an audible whistling noise when the engine is under acceleration, which not only affects vehicle performance but may also lead to more severe engine issues if left unaddressed. Many owners of the 2015 Ford F-150 EcoBoost engine have experienced similar issues, indicating a widespread design flaw. While the immediate issue is the noise and potential performance degradation, prolonged exhaust leaks can lead to more serious problems, including increased emissions and possible engine damage. The warping of the manifold could also lead to more severe mechanical failures if not properly addressed.
