A known Ford defect on the 2017 3.5 ecoboost engine is when the manifolds, improperly designed and installed, warp and snap off the manifold bolts holding the manifold to the engine. The result is a great deal of extremely hot exhaust fumes being emitted in the engine compartment rather than out the end of the exhaust pipe. There were NO messages, lamps or other indicators of the manifold failure until a wheezing, rattling sound was emitted.

I have had many issues with this vehicle. The engine leaks oil onto the exhaust causing the engine to smoke, the engine uses antifreeze, the transmission will downshift at highway speeds to such a low gear that I need to put the van into neutral so that the engine doesn't blow up. It uses brakes quickly, (New brakes every 10,000 miles or so). Gas milage is less then 12MPG as well.

I have wrote to you before on this, but today (4.29.25) while driving downhill at 65 mph, no cruise control on, my van downshifted ON ITS OWN down to third gear and luckily, I was smart enough to shift the van in neutral and then back to drive or I would have blown up the engine. This is not just happening to my van, I have a friend who has purchased one and the transmission has gone out with only 35,000 miles on his van. My van is leaking oil and leaving spots everywhere it is parked, and it is using antifreeze at the rate of about a gallon every two weeks. This engine is total junk and neither the dealership, Ford, nor the federal safety agency are doing anything to correct this. Eventually, these engines are going to kill someone by locking up at highway speeds. Enough is enough! Ford needs to fix or replace these engines before someone dies!

I have sent this before, but my vehicles transmission will downshift, (at highway speeds), to a lower gear. I always have to put the van into neutral and then back into drive to get it to drive normal again. Also the van leaks oil onto the manifold which starts smoking. My van also uses antifreeze and I need to refill the coolant about every 2-3 days. This ecoboost engine is dangerous.

The transmission will downshift when deceleration and will actually throw you forward in the seat due to dropping into a lower gear. Vehicle has also developed an oil leak where oil is dripping onto the manifold, possible engine fire hazard. Engine is losing coolant due to possible blown head gasket.

Transmission will downshift on its own when vehicle is decelerating making engine RPMs over rev. Only way I have found to prevent this is to shift to neutral and then back to drive. I don't like doing this because it could accidently get shifted into reverse while driving at highway speeds! Valve cover leaks dripping oil onto the exhaust manifold causing the vehicle to smoke very badly and could possibly cause a fire.

1. Vehicle has oil leaking out of valve covers so bad it starts smoking from under the hood. 2. Transmission will stick into low gear and I have to put the vehicle into neutral to get it to start shifting correctly again. Vehicle will also pulsate speed with transmission growling. 3. Turbo chargers not operating correctly causing Vehicle to buck and hesitate under acceleration.

Vehicle has 140,000 miles on it. 1. Has valve cover oil leak where dripping oil is dripping onto the manifold and starts smoking. I talked with the dealership, they said they wont fix it under their "Lifetime warranty". I am concerned it will start a fire. 2. The transmission will suddenly downshift and seems to lock into lower gear when decelerating. Only way to get it to stop is to put vehicle into neutral while coasting and then back into drive. I am afraid its going to lock up and cause me to spin out. 3. The engine has a turbocharger issue in which when I try to pull out into traffic, it will sometimes buck, hesitate and backfire before it accelerates. Eventually I am going to try and pull out and it's going to do that and I am going to get hit! It seems to do it while coasting and then when accelerating again, that's when it happens. I took vehicle to dealership (Johnson City Ford) where they provide a "Lifetime powertrain warranty", but they are telling me that unless I have all service records, they will not fix it under the warranty. The only thing I have done with this vehicle is oil changes when the vehicle tells me it's due, Tires and brakes. I also called "Contact Ford" about the problem, and they basically told me it's not their problem, so there is a record somewhere of me contacting them Twice.
