While parked and shut off at a gas station in Lakeside, CA, my 2015 Ford F 150 XLT spontaneously caught fire under the hood. The fire appeared to originate in the fuse box area, specifically where the fuel pump relay is integrated.

My 2015 Ford F150 has 108K miles. While driving on 2/21/23, the engine started missing, several engine warning light began illuminating. I was able to pull to the shoulder and stop the engine which was missing badly. After allowing the engine to completely stop and turning the ignition off, I allowed it to settle for a moment, then I restarted the engine. I placed it in gear and attempted to drive again, but the same missing and instrument cluster faults recurred. At this point, I had it towed to Loveland Ford, in Loveland Colorado. After evaluation, I was notified the Throttle Body had failed which also caused the instrument cluster faults. …
Throttle body failure approx every 45,000 miles. Bought F-150 new, now driven it approx 135,000 miles. Failure occurs when driving a various speeds, incl 75 mph. Engine shuts down, complete loss of power. DANGEROUS situation; safety at risk! Unexpected & random loss of power - w/ passengers aboard - in various traffic situations. After engine shuts down, restarts, then randomly shuts down until a new throttle body is installed. First throttle body failure repaired (=throttle body replaced) @ Ford Dealership in Price, UT. 2nd failure repaired @ Ford dealership in Hamilton, MT. Both covered by extended warranty. 3rd failure repaired [redacted] @ Hamilton, MT @ $324.55 personal expense. Check engine light warning occurs.
at 63000 miles in June 2021, randomly while driving, it presented warning "Hill Start Assist unavailable" and other traction control warnings,, throttle goes to idle in traffic, vehicle coasts and dies. Key off & on restarts it. Code P2112. Ford dealer replaced throttle body motor under extended warranty on June 3, 2021. MotorCraft Part has 2 year warranty. On June 17, 2023 (14 days out of part warranty), at 93,000 miles truck does identical behavior. Starts & runs fine, presents warning with random frequency (4 times this morning) at various speeds from 30 mph up to 75 mph in freeway traffic. Throttle goes to idle, truck coasts at 3-5 mph until ignition key recycled. happened this morning at 65 mph on freeway in construction zone with no safety shoulders. VERY dangerous!!!
Chech engine light keeps coming on. Dealer said it was an evap canister issue, I told them warning had come on prior for check fuel fill cap. (Capless). Said they needed to replace purge cylinoid. So as I'm paying $500 for the repair, I'm told this might not fix the issue. What? Started with small evap leak. And fuel door codes. That only came on at 1/4 tank used. Now it's a large leak that comes on every time I start the engine. And I got the check fuel fill door warning again. I've done every trick listed on forums to clean and lubricate the fuel fill door, it did help for a while but as stated above problem is now much worse. Dealer should know how to fix this issue once and for all. Forums note that this is a common problem with no quick solution.
Warped exhaust manifold. The design of the exhaust manifold where it connects to the turbo is not engineered correctly and only has 2 mounting studs. The heat generated from both the exhaust and the turbo is more than the 2 manifold studs can handle and the exhaust manifold warps causing a broken manifold stud and exhaust leak. This is clearly an engineering design fault and this part should be recalled. Loss of performance, and fuel economy. No warning signals in the vehicle. This is the second time that the exhaust manifolds have warped. The first time was covered under the powertrain warranty and replaced by the dealer at +/-60,000 miles. This problem has now occurred again and is no longer covered under warranty at 86,000 miles
