2018 Mustang GT Clutch/transmission/engine rattle 2200 rpm

Описание: UPDATE: Ford gave me a full refund under CA Lemon Law.

2018 Mustang GT manual. Build date is 11/16/2017.
Noise occurs between 2000-2500 rpm. Usually hear it when shifting from 1st to 2nd and 2nd to 3rd. Noise is loudest in 3rd gear when holding rpm at 2200. Tech found cylinder damage to 5-8 and recommended full engine replacement. Ford only approved a new short block. Replacement took almost two months so Ford gave me a refund under CA Lemon Law.

Here is a related OASIS note that is a good explanation for what is probably happening. But the 5.0L does not have forged pistons so could be anything (wrist pin, skirt clearance etc.).

Some 2016 GT350 Mustangs might exhibit Piston Rattle from Idle to 3000 RPM

Some 2016 Mustang GT350 equipped with the 5.2L engine may exhibit a rattle or rapping type sound during cold operation at light loads and speeds from idle-3000 rpm. The noise will be most noticeable during light acceleration in the 1500-3000 RPM range and may also be noticeable in the 800-1200 RPM range with neutral throttle blips. This sound is caused by the piston motion in the cylinder bore. This is an inherent characteristic of the forged aluminum pistons utilized in this high performance engine. Once the engine reaches operating temperature the noise will diminish, although it may still be noticeable even when fully warm. There are no durability concerns with this sound.
