Filed Sep 7, 2025 · Transmission · VA

Transmission makes a sudden hard down shift..... and it always throwing codes ... well maintained but getting too expensive.... 2017 F150 ecoboost 3.5... jumped into lump mode while between 2 semi trucks and one one my side also.... I held down on the throttle so that it wouldn't stop in between the semis and finally had a chance to pull over.... turn my vehicle off... it drove normal but now have another code... possible misfire.... cylinder 1 and 4.... last month it was cylinder 3... I've talked with Ford on helping with the bill they said they don't do that... but offered me some other things that may be covered undered some other recall.... every other month it's something... ooo yeah, had cam phaser done also.... out of pocket... can't find the cam phaser bill but if you need it I can request a copy from the mechanic shop....

My F150 has an inherent design defect which makes them predisposed to leak coolant, including allowing the coolant to seep into the engine cylinder, which causes overheating and cylinder head cracking, and can cause the engine to misfire, suddenly stall, or even catch fire while driving. My truck currently has this issue it have white/gray smoke coming from the exhaust and has a coolant leaking issue causing it to come out of the tailpipe. This is 100% a manufacturing issue. I have always had my maintenance done at the dealership, examples of oil changes, and things like that. I have owned the vehicle since brand new engine issue is at no fault of mine.

Which caused horrible vibration. And very poor dieverably. Ending up needing an engine replacement at 121,00 miles. And cost 14,000 to do. Happened in February and still waiting for the engine replacement to be done. Ford is behind on motors.

2017 Ford f150 super crew 5.0L V8 engine. Started rough idling at stops when in drive about 5 months ago. It started just completely dying while in idle but never threw a check engine light or any code. Ford dealer didn't have an appointment for weeks. We took it to three different licensed mechanics who could not recreate the issue. We just got the truck back after the 4th stay in the shop and the mechanic mentioned the VVT solenoids being bad. There was an issued recall for this exact same problem but not for the 5.0L on 2017 Ford F150. After some more digging, I see hundreds of this exact issue on the Ford forums.

Problem started in May 2021 at about 70,000 miles. Initially truck would idle rough at stop lights, stop signs, and when parking RPM dropping to 500 not all the time. Then in August 2021 progressively got worse and even started idling rough and stalling at intersections, stop signs, and parking. When there is a lot of moisture in the air it is worse. One rainy night it stalled at three intersections in a row. You have to put vehicle in park and put some pressure on gas pedal to keep RPM's up. Someone is going to get hurt very bad in a accident or on the freeway from these trucks stalling out. My truck is currently in the dealership and they are initially saying they see no issues as there are no codes. Online there are many many of the same issue reported. All with the exact same characteristics of rough idle then stalling and no codes or check engine light.

Took delivery 5/8. Called dealer service department 5/17 to see about rough idle and a few minor cosmetic issues. Dropped off 5/25, service advisor called 5/26 to tell me it is blowing oil through the pistons and they are going to have to replace the heads per a tsb. I started research on the internet and found ford tsb 17-0007. Seems that f-150s made between june and october 2016 might have this problem. The technician plugs the truck into the dagnostics machine and if your vehicle is one of the unfortunate ones, it either gives a code for head replacement or engine replacement. Why are these vehicles waiting to be sold before checking a code? Here I have a month old "new" vehicle that has been down longer than driven. I have been communicating with ford corporate since 5/30 requesting either a new engine or vehicle. Replacing the heads should not be an option when a consumer has 400 miles on an engine. Should be getting an answer from ford in the next two days, but still, if I am forced to accept new heads, the reduction in value of the vehicle will be tremendous.
