NHTSA Complaint #11606974 — 2023 FORD F-250 SD

Upon starting the vehicle the engine made a rattling noise.I turned it off and restarted it and the noise continued. Turned it off again and the noise stopped. Brought it the dealer with a video/recording on my wifes phone so they could hear the noise. The truck was there over a week with the service writer saying they could not duplicate it. The truck was there a few more days before the service writer told me they received a service bulletin instructing them to up the pressure on the oil pump. They did that and told me the truck was fixed.I went out yesterday and the noise has returned, again my wife recorded the noise. Bringing it back again to the dealer. We are afraid to use this truck as we dont want to have an engine failure. This has also been to the dealer for brake squealing and the instrument cluster going totally blank, again being told it cant be duplicated. this truck has 3400 miles on it.
