NHTSA Complaint #11502919 — 2019 FORD F-150

cam phaser recall performed by dealer prior to 36k miles. at 36k miles, returned to dealer with same rattle noise from engine, dealer said was noise from backpressure at exhaust near turbo. at 40k miles, engine failed in middle of intersection. Advised by dealer the engine is total loss and will need to be replaced, declined to agree that the cam phaser timing chain was the result, stated that the issue was in the lower end of the engine, which is where the oil pump is....that runs off the timing chain. prior to the failure, I experienced slight power loss, complete momentary power loss shifting between gears 2 and 3, slight knocking noise from the engine that mimicked a diesel engine sound, as well as the stated rattle noise.
