2021 FORD F-350 SD- Cleveland, TX
Cold side intercooler boost tube cracked due to constant vibration impact from coolant overflow hose routed directly above and on top of it. Part and vehicle is available for inspection. The split in the boost hose caused me to loose power while attempting to merge onto a road, almost being hit by another vehicle. After research there are multiple other instances of complaints of the same thing happening to others and multiple aftermarket manufacturers producing replacement and upgraded parts with references and warnings of the same thing happening for the last 10 years. No warning lamps or symptoms prior to failure. After failure no warning lamps but could hear an audible hiss. The vehicle has not yet been inspected by the dealer or police. I was told by their parts people it is a regular failure and the part costs typically around $200 and they only sold it as a full part and not just the rubber replacement hose althought they are separate parts connected with hose clamps.

2021 FORD F-350 SD- Hyrum , UT
Back up camera screen goes blue when put in reverse. Then after 20 seconds says camera unavailable see dealer. I had dealer repair with a software reset. Worked for about 2 weeks then same symptoms. Noticed Ford has a recall for the same symptoms on other vehicles but for some reason F-350s are not a part of it. Would suspect the truck uses the same camera system as the other ford vehilces under the recall. Ford needs to step up and cover the F-350s
