2017 FORD F-150 Complaints

I was driving at 62 MPH and the truck suddenly down shifted. It is a 6 speed transmission and I was in 6th gear when it down shifted. The indicator that displays what gear it is in disappeared but the rpm went form 1,500 up to 3,000 very abruptly. In fact, when it happened, the back wheels actually hoped up and down a couple of times. I tried to shift in manually but nothing. I stopped the car, restarted and it would not upshift. I put the car into neutral while I was rolling and then put it back into gear and the transmission stared to act normal.

The intake manifold on this series of trucks is a commonly found failure. It is costly as it requires complete disassembly and reinstall for internal components, that lead to poor performance and eventual engine damage if not repaired. I had a SES code 2019 flag for this and required me to have >$1500 repair to resolve by a reinstall of a new intake manifold by the Ford Dealer on May 21, 2025. This should have been recalled with the vast number of problems seen online and that the dealer had this part in stock as it is so common. I was only 50d after my extended ESP warranty when it went.

Truck has been downshifting at low gears prior to this main incident. Usually at low speeds between the 1-3 gears. But today I was driving down the highway at approximately 65 mph in the 6th gear and without warning it seemed to electrically down shift into 1st gear. I describe it as electrically because the Rpm’s dropped almost instantly for a second and seemed to reboot. Which is extremely dangerous especially on a busy highway. Not only could I cause me to crash but also others to wreck into my self and poses a incredible risk for my fellow drivers And this is the reason for my complaint. Going from the 6th gear to 1st has to be some sort of recall and or an indication of far greater problem. What is even more odd there have been no check engine lights on for any of these instances.

My apologies, I sent prematurely, case number 11664674 is already open, but I wanted to add to it. My 2017 Ford F-150 with the 2.7L EcoBoost engine has experienced recurring coolant loss and is now showing signs of internal engine damage. I initially reported the issue to the Ford dealership in November 2024, but no issue was found. On May 23, 2025, the dealership told me I need a new engine. My independent mechanic suspects cracked intake valves or internal coolant intrusion — a known defect in the 2.7L EcoBoost engine. This appears to be the same issue identified in class action lawsuits and previous NHTSA complaints. I feel the vehicle is now undrivable due to my fear of imminent engine failure. My extended warranty expired in December 2023, but the problem started well before that with white smoke coming out of the tail pipe upon cold starting. I am requesting NHTSA investigate these recurring issues, as this appears to be a widespread and unsafe defect affecting multiple years of the Ford 2.7L EcoBoost engine.

Internal coolant leak issues leading to engine failure. Know defect publicly acknowledged by Ford as there is a class action lawsuit for the later models, but same engine (2.7L eco boost) My gauges do not register that my coolant is low or empty. I have taken it to the dealership twice in 6 months for the complaints of coolant loss. An independent mechanic suspects the same issues as the known defect leading to engine failure
