VALVE TRAIN FAILURE
.2016 F-150 Ford Truck. Purchased from a used car dealership. While driving the truck on a freeway at about 40 MPH, accelerated to 55 MPH and changed lanes. Engine went into limp mode. Check engine light flashed. Started to deaccelerate. Moved vehicle over to shoulder. Fault codes: P0340, P0344, P0365, P0369. This truck has a 2.7L EcoBoost engine. Mileage is about 130,000. Two mechanics from different companies evaluated and found timing chain broke and sheared the keyway on the crank shaft where the timing sprocket is located. There was not prior warning to indicate any issues.
Our truck was smoking from the exhaust and we took it to the local Ford service department. They determined the oil pan is leaking, there is a coolant leak from the engine, requiring a new engine, and also the need for turbos. These are the EXACT issues that are included in this service bulletin making dealerships aware. If this is such a widespread problem with these trucks, why is there not a recall to make proper repairs?

Our truck has been experiencing downshift to a lower gear and the powertrain warning lamp wrench symbol in the instrument panel cluster comes on. This has been happening from about 4/1/2026 and ongoing.
VEHICLE SAFETY COMPLAINT STATEMENT Prepared for NHTSA Submission Regarding Recall 26V237 / 26S28 To: National Highway Traffic Safety Administration (NHTSA) Subject: Report of Accident and Vehicle Control Loss Due to Defect Specified in Recall 26V237 VEHICLE INFORMATION: Year/Make/Model: 2016 Ford F-150 VIN: [XXX] INCIDENT DESCRIPTION: In March, while driving during a snowstorm, the vehicle experienced a sudden and unexpected loss of traction and stability. Without warning, the rear wheels appeared to lock or drastically reduce speed, causing the truck to slide uncontrollably and strike a roadside barrier. Following the initial impact, while attempting to move the vehicle to a safe location as instructed by insurance/authorities, the engine suddenly stalled and shut down completely while in motion, nearly resulting in a second high-speed collision with the vehicle ahead. CORRELATION WITH RECALL 26V237: In May, I received a Safety Recall Notice (Ford Recall 26S28 / NHTSA Recall 26V237). The description of the defect—an "unexpected downshift to a lower gear causing abrupt wheel speed reduction and rear tire slide"—exactly matches the catastrophic event I experienced in March. The recall also notes that the engine may malfunction or stall, which occurred during my incident. IMPACT & DAMAGES: The insurance company evaluated the damage at approximately $6,000 for structural repairs. However, the vehicle remains unsafe and mechanically compromised. Despite the structural fixes, the core safety defect involving the transmission and engine software remains unresolved as Ford has stated that a remedy will not be available until July 2026. REQUEST: I am filing this formal complaint to document that the defect in Recall 26V237 resulted in a real- world accident and total loss of vehicle utility prior to the notification being sent. I request that NHTSA takes note of this incident as part of its oversight of Ford's recall execution, as the vehicle is currently un-dri INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATIO

Exhaust manifold studs broke off (as do they all break) and turbos oil lines leak engine oil causing fire. By the time I stopped and got out there was already flames coming out from the hood. It was so fast I didn’t have time to be get my firearms or tools out. I have not notified Ford or and I only had liability insurance on my 2016 f150. 3.5 eco boost.
Oil pan leaks. The F150 just crossed 70,000 miles. At just under 60,000 miles the truck had what the Ford Service tech described as a weap from the oil pan. He said it was a costly repair so just to watch it. At 65,000 it was a steady drip when the oil was warm. Now at 70,000 the Ford dealer is recommending a replacement. What I have learned is this is a common failure on 2015 to 2017 F150s with the 2.7L engine. I suspect this was happening earlier but the Ford Dealer was relucant to bring it up as it would have at the time been covered under warranty. I have also now learned Ford is on its 3rd TSB for resolving this common leak at the oil pan. Hopefully this will warrant a recall response from Ford. From research this is a very common failure and engine damage will occur if the leaking oil pan is not repaired. Please investigate as I suspect there are numerous complaints. Thank you.
While driving, the hill descent fault error would pop up on the instrument panel, the truck would begin to shake, and the gas pedal would no longer work. I would have to pull over, shut the vehicle off for a few minutes and restart it. This happened multiple time while driving on the highway and in town. After sitting in the driveway for while trying to get repairs scheduled, the issue got worse, and I would have to pull over every one to 2 minutes due to this issue occuring.
While driving the instrument cluster would flicker and then the truck would down shift gears. The first time it did, it dropped from 6th gear to 3rd gear at 70 mph, and the next time it dropped from 6th to 1st around 65 mph. It also occurred at lower rates of speed.
Very slowly a noise started on the passenger side of the engine and kept getting louder, didn’t know if it was a vacuum hose leak or something else. Finally the noise was very loud especially when accelerating, I took to my local Ford dealership to have them find the noise and let me know. 3 days later, I get a call from the service writer and he tells what the problem was, so I told I would be by to pickup the vehicle and he tells me that I can’t as the engine was taken apart on the passenger side. I told him, I didn’t authorize him to do that, only to find the noise, needless to say I was quite angry and I had no choice but to have them repair the exhaust manifold bolts which had broken towards the rear of the engine. After much discussion, he told me that this was a normal incident with this engine/vehicle combination due to heat buildup. I asked if there was a service bulletin on it and he played dumb and said no there wasn’t after telling me it happens a lot. To me this should have been covered under the long term factory warranty. The vehicle only had 61,500 miles on it. After hassling with him, I asked the price and it was going to over $6000.00, Again I am very angry, as I have no choice, and they end up replacing turbo parts that were just replaced 5,000 miles ago. I can’t believe how they handled it, no recourse and out of pocket $6,000. I made numerous calls to Ford in Michigan and got the total run-around. I really like this truck as it has served me well. Since, the service writer admitted that it was a continuous problem with this issue, as they have steel bolts going into an aluminum head, of course with heat there will be problems. I have heard of a few F-150 owners on a Ford website with the same issue and they ask the same thing, why not a recall? I would love to get reimbursed for all that money I had no choice to put out, as I would taken it to a certified mechanic that does all my work now! Total BS on the dealer and Ford!

Transmission downshifting and electrical issues
On 11/22/18, Thanksgiving Day, I was driving our 2 year-old Ford Lariat F-150 Supercrew alone on a backroad in Northern Colorado. I was going approx., 65MPH when out of nowhere the truck downshifted from 6th to 2nd gear and caused the truck to lockup, slam me into the drivers seat, and stop in the middle of a thankfully empty road. The engine made a popping sound. The truck made creaking noises from the wheels as I drove it home. It immediately started leaking oil. I took the truck that was still under warranty to the local dealer we bought the truck from the following week as it was a holiday, where I left the truck for a few days, and upon pickup, was told my concerns could "not be replicated" other than an oil leak. I spoke to the 'managers' in a backroom who were 2 men who LITERALLY told me I just needed to learn how to drive my truck better. I asked them if they had actually driven the truck to LISTEN to what a truck still under warranty sounded like after it how downshifted for no logical reason and dead stopped in the road after locking up. They did not. I told them I thought they wiped the codes and were relying on computers to diagnose issues and if Ford knew they had a problem and were hiding it, and people died, Ford would be sued. True story. I reported this to the FBI due to the response because it was disturbing. I know what happened to me when our truck downshifted. If I was on the highway people would have died. Period. I have 10 years worth of documents and all the Ford notes on everything that went wrong with the truck after that catastrophic event. I have 4 official complaints filed with Ford Corporate starting in early Feb., 2019 through late 2025. Shoutout to FormulaFord Rutland for being kind and ethical. I have pictures and video of our truck acting like "Christine" because the software goes haywire when it feels like it. I have the oil leaks and sounds from the wheels recorded on video. Ford Fusion did the same thing. Ford knows. Not ok
The truck would fall out of gear, going down the highway it would shift into 1 or 2nd gear reving the engine. I would have to put it in neutral and at times have to shut it comeplete down to have it reset.
