Okk Main issue is what everyone calls the “Death Wobble”. It has done it countless of times since I’ve had the truck. Even after I bought a New Fox Single steering stabilizer. I have replaced quite a few things under the front end that I was told “Could” be why it kept doing it. The most recent I’ve bought for the front is brand new Fox Shocks just like the ones I have on the back and it still does it. I’ve had the front end aligned a couple times since I’ve had the truck and rotated my tires once too. And to this day it Still does that death wobble. It scares me every time too still. Im afraid ima end up in a wreck or cause a wreck bc of it. Another issue is I keep having this warning pop up saying “ Engine Temp too high reduced engine power “ bc it thinks the engine coolant is too low which it’s Not. And when I scan the code through the OBD port it just says “Engine oil temp sensor too low/too high”. I had the Ford dealership in my town put a new Oil Temp sensor in it but it still throws a code just about everyday I drive it. Another issue I had was the High Pressure fuel pump on the front of the motor go out Literally while I was sittn in my driveway at night after just driving it not even 3 miles down the road to the store to grab a few things. And it ran fine like normal but soon as pulled in the driveway an was rolling my windows up about to go in it just died on me an had to get it towed to the Ford dealership in my town. They looked at my fuel an said my fuel was fine with No contaminants in it. I was just Unlucky they said so that was basically 10k out my pocket to pay for a Whole New fuel system. The Death Wobble is my most concerning issue but other than that the truck has been awesome.
