My truck is having the same issues as listed in the recalls but isn’t on the recall list. Running rough dash board turns off and loses power to the cab. Low voltage light comes on but batteries and alternator test fine. Factory installed lift blocks have cracked and caused can bushings to fail.

I purchased my 2008 ford f250 in 2015 from a dealership in burkburnett, tx. The truck started loosing coolant from what seem to be the lower radiator hose. That leak stopped but continued leak coolant from but was not visible. Then the coolant filler bottle started collecting a black fluid and I was told that it was engine oil. So, I was getting oil in my antifreeze. The radiator was drained and refilled with coolant but I still found oil in the coolant filler bottle. Right around thanksgiving 2019, I decided to trade in the vehicle and drove it to a dealership 50 miles away. They test drove the vehicle and the engine locked up after the test drive and has not started since. We were given an estimate of $11,000 to clean out the oils in the engine. The pickup is not worth that much according to the lienholder. The vehicle is now sitting in front of my house and has been since the new year after we had it towed from the dealership 50 miles away to our home.
