One problem related to engine knocking noise has been reported for the 2012 Ford F-350. The most recently reported issues are listed below.
While driving my vehicle to get on to the freeway, the engine started revving and rattling I could smell something burning. When I tried to press on the brakes it wasn't working than the steering locked. I hit my emergency breaks put on my hazard light and turned off the car until a police officer arrived. I purchased the vehicle on 2/28/2020 and when I returned to pick up the truck the next day they could not produce the keys, this took about 2 weeks. On 04/06/2020 approx. 2 weeks after picking up the truck the it wouldn't start, I jumped the truck at which time there was a rattling and knocking sound in the engine, I took it back to the dealership for servicing. I got the truck back again a little over 2 weeks later on 04/23/2020. I feel the truck is so unsafe that it will cause me to get into an accident placing my life that of my family or another driver in a separate vehicle at stake. Upon reviewing all of the documents none of the documents have the same odometer reading and the number is approx. 24000 off.
