While at idle with a hot engine, the vehicle will intermittently shudder and stall. Once a check engine light appeared with the vault being cam shaft sensor. The check engine light has not reappeared to assist a mechanic as to the specific fault. The engine still has an idle issue which seems to be common with this engine and model year according to auto forums I have visited.

Truck randomly downshifted while going high speed, causing tires to lock up.

- Marion, OH, USA

2016 f150 3.5L eco boost V-6 was purchased recently from used dealership. Upon taking possession the vehicle would shut down while driving. I would need to get to the shoulder of road, put truck in park, turn off vehicle and then restart. It-??s happened 20 times in last 30 days. I-??ve taken to dealership 5x and they are unable to resolve, diagnose or offer any help. Online, many other owners have noted same issue. Doing 65 on fwy and truck suddenly dies is big deal! Ford does nothing. Error message on dash says something about stability track. When restarting engine, it turns over many times as if flooded but then starts.

These vehicles with the 5.0L engines have a problem with cam phaser timing which causes a rattle in the engine it also causes the engine to stall sometimes it causes the engine to stutter, in my forum I have saw this complaint from guys with vehicles ranging from 2015 up to 2019, this is a problem Ford knows about but haven't done anything about it, they have since developed a new cam phaser timing set but, they didn't not do a recall on this, this is a problem that occurs several times a week.

after warming up vehicle would not idle right when coming to a stop. it was intermittent at first but then got progressively worse. While sitting at a stop light rpms would go up to about 1000 then surge beyond without any input from me and then drop to below 500 sometimes killing the engine at what was suppose to be idle. there were not codes or check engine light but took to dealership when it first started happening they said they couldn't find anything wrong. during this time i replaced spark plugs, coils and timing sensors trying to fix but it those repairs didn't take care of it. but then it became more consistent and took it back in and they were able to confirm the problem occurring and after testing they recommended and changed out the timing components and all cam phasers, phaser filters and all vct solenoids

Oil pan leaked once before I bought the vechicle and once again at 90,000 miles and once again at 143,000 miles. Ford knows there is a problem related to the oil pan gasket and plastic oil pan. Ford upgraded the seal but it will still leak because the pan will get warped from the heat. On the ford forum multiple people have reported this as a problem as well.

Dec 2021 - Normal maintenance check including oil change. Technician informed me about leakage at oil pan. TSB 23-2083. Replaced defective oil pan. Jan 2025 - Normal maintenance check including oil change. Technical informed me about leakage at oil pan. TSB 24-2098. New design oil pan & replaced defective oil pan. Ford customer service notified. I requested if there was any financial compensation associated with these 2 repairs under respective TSBs. Answer - out of warranty. Internet searching - seems that these leakage at oil pan is known issue by Ford including a redesigned oil pan. Question = why is there no safety recall yet ?? These TSBs only give info about defect and how to fix. If vehicle is out of warranty, the repair cost is up to consumer. Consumer may not understand total impact = SAFETY issue because no oil then engine can malfunction or overheat resulting in vehicle stoppage on road (potential crash).

My 2016 Ford f150 engine failed. The Ford dealership found the turbo & the valves failed. 2 pistons cracked due to excessive carbon build up & the valves failed. The motor failed causing engine to stop suddenly.

- Omaha, NE, USA

Under light acceleration at highway speeds developed a misfire. Pulled over immediately and shut the vehicle down. Started vehicle up again and misfire was still occurring even at idle. Went straight to dealership where service department diagnosed as engine issues related to TSB 19-2384. Known defect to Ford related to a "concern with cylinder head valve guides". Advised by dealer this required new cylinder head but recommended entire long block replacement. Upon further discussion, manufacturer knew about this issue and did not recommend repair until symptoms developed because of their defect. Outside of warranty so dealer said they could provide no payment assistance. Spoke with Ford customer care and they informed me of the same and referred me to NHTSA.

At approximately 62,000 miles, a loud noise started from the passenger side of the engine, car was taken to the local Ford dealership for repairs, and it was determined that the bolts for the exhaust manifold broke which was causing fumes to enter the passenger compartment. Repairs were made at my cost of $6000, and calls were made to Ford Corporate for monetary help but they declined any help at all!

I was getting married and setting to go a getaway immediately after we wed. I got a tune up and go my vehicle read. After the tune up it the drive felt great. So me and my wife took to the highway, and as my vehicle began to accelerate the engine began jitter as I press on the gas peddle. The car would not go past 50 mph. As I kept my feet on the gas you can feel the whole car shaking, then the eco boost kicks in and it immediately accelerate at a high rate of speed and as attempt to control the speed by letting go of the gas. The vehicle shakes as it looses power and settles on 50 to 60 miles shaking until the eco boost kicks in. It was a two hour ride and I couldn't look back just pray. Through out the ride it was the same thing over and over again. My wife and I were in constant fear, because I felt due to the erupt increase in speed I was putting other motorist at risk. The engine light came on and a wrench symbol and tire symbol came on. The component or system that failed or malfunctioned involves the eco boost. It appears to be the same recall reference NHTSA # 24V-635 & Manufacturer: # 24S55. My vehicle presently has 78,000 miles on it and it should not be doing that. I have also looked at other problems with the 2016 Ford F-150 Ecoboost as being the web belt system and head gasket failure. However, whatever is the case anyone with this type of vehicle and experiencing the same thing is catastrophic the public safety at large and it cannot be ignored. Ford must correct this problem before someone end up dying as a result of this problem. Thank you for taking the time to read my story and I pray this may help you properly investigate my experience. I can have my truck available for anyone from NHTSA to inspect. Presently there is no data regarding the problem with this particular vehicle.
