Death Wobble Severe steering problems occur with this vehicle. Especially when hitting even a slight bump in the road. When pulling a trailer across a bridge, it became so severe that the truck and trailer changed lanes and I had NO control. This problem occurs regularly and is a very dangerous situation!

The exhaust manifold bolts broke and it’s leaking toxic fumes in the path of the cab and it gives me a headache I’ve done research and this is a common issue

The truck has developed a significant knock coming from the intake manifold. It is loud enough to hear with the hood closed. The problem exists warm and cold. The knock was verified by Sunrise Ford in Fontana, CA in December of 2024. The Dealership had another F250 on the lot with the same 6.2 engine and that it also has a knock coming from the intake manifold, so they considered the situation "normal". There is a significant amount of information available that the knock is related to an impending failure of the Intake Manifold Runner Control (IMRC). If the IRMC fails, the parts will go into the combustion area and could cause an immediate catastrophic failure of the engine. At best this problem creates a loss of power and a pulsing vibration at idle.

Message #6-Pre-collision assist not available. I thought if I shut the truck off it would reset. When I tried to restart the truck it did nothing. Had it towed to Archie Cochrane Ford in Billings, MT. They replaced the DEF wiring harness. 2nd incident on [XXX], drove through rain on way to Provo, UT. Service engine soon light came on with all the same messages + five other messages. Had it towed to Larry H Miller Ford in Provo, UT. They replaced the Battery Junction Box. Drove to Yuma, AZ without incident but had them look it over and they could not reproduce the issue. Drove to Dickinson, TX, encountered fog on 1/3/2025. Incident #3, drove to the gas station on [XXX], started the truck up and the same messages came up. Roads were dry, although it had rained the night before. Drove straight to McRee Ford where the technician observed the issue firsthand. While the vehicle was in park it was constantly surging. We researched online for the same problem and have found others that have had this same type of issue. We have had to rent cars when the truck was in the shop. We believe this is an engineering issue and Ford should fix the issues without charging. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORM
