[QUOTE="Art Vandelay, post: 15877493, member: 189090"] Hi, Today I took my car to the dealership to see about a rattle noise coming from the engine. I described the problem to them like this: "A rattling noise while accelerating slowly between 2500-3000 RPM" They got back to me with Special Service Message 46173 that says: "Some 2016-2017 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." That sounds very much like my description of the problem. So I guess most of you are experiencing this rattle and just dealing with it? Thoughts? [/QUOTE]
