While in 6th gear driving on the highway at 70 mph the truck downshifted to 3rd and drastically decelerated. When this happened the instrument display went from having all 6 gear numbers viable to only 1 - 3. It had to be put into Manual Mode and shifted into 6th manually. This happens twice in the same trip.

Truck started making a loud sound from engine compartment on startup after towing camper 150 miles. The sound started to get louder and started to notice exhaust smells in the cabin. I took the truck into dealer to find out that the exhaust manifolds were warped leaking on both sides of engine due to a stud being broken that holds the manifold in place the tech said it sounds like a diesel. The service advisor at the dealership said that it is a "common problem" on the 3.5L twin turbo engine. The cab of the truck fills with the exhaust fumes to the point where the driver gets headaches unless the windows are open. I asked if there was a recall on this problem and they said NO. The same manifolds was used for years on that motor, since then Ford redesigned the manifolds to use extra studs into the heads that are already there but now want the consumers to pay to install the new design to keep the fumes out of the cab. Looking online it seems to be a problem that the turbos are heating the manifolds to the point that they warp and snap the only stud used on the rear portion of manifolds for owners that tow with the truck (that has a tow package and rated at 12500 capacity) FYI I'm only towing 5000 pounds. My concerns are that the exhaust fumes can overcome the driver an cause them to pass out or become impaired by the carbon dioxide poisoning.

- Melbourne, FL, USA

Problem: Engine unexpectedly goes to idle speed after accelerating up to highway speeds. Cruise control was not engaged at time of failure. This has happened three times, all after a cold start up, and all within 2 miles of home. The most recent occurrence being 6-19-25. At time of failure, multiple warning screens come up on the dash, including "Hill Start Assist Not Available", "Service Advance Trac", "See Manual" (with a picture of a wrench). No check engine light comes on, and no error codes are set. Engine does not respond to accelerator pedal, engine will only idle roughly. When this occurs, the only remedy is to pull over to the side of the road, shut off the engine, then restart the vehicle. Each time this has happened, the engine starts and runs normally with all warning messages cleared from dash. Safety Concern: Unexpected loss of power can increase the likelihood of an accident, especially in heavy traffic. This truck is used frequently for towing, and an unexpected loss of power can create a loss of trailer control. Dealer Contact: Last September when this issue initially cropped up, the truck was taken to our Ford dealer for diagnosis. They kept the truck for approximately two weeks, driving it daily without having the issue reoccur. They performed diagnostics on electronic modules but found no concrete issue. Inspection: Truck has not been inspected by the manufacturer, only the dealer. Warning Lamps and Messages: "Hill Start Assist Not Available", "Service Advance Trac", "See Manual" (with a picture of a wrench)

Truck is at 135,000 miles and needs its 3rd oil pan due to faulty engineering. Ford is not covering repairs or offering assistance for previously repaired products. I bought truck certified pre-owned with extended warranty. The oil pan was cracked at that time and needed to be replaced at first service. On average oil pans are lasting less then 70,000 miles. How is this allowed to continue to occur.

I was driving at around 45mph and my truck suddenly downshifted automatically and almost brought me to a complete stop. It finally shifted back up and I was able to return to the proper speed. If this would have happened at higher speeds I could have been in an accident. Event at 45mph, had I not had my seatbelt on it would have thrown me into the steering wheel.
