2010 Hyundai Genesis 3.8 4dr Sedan (3.8L 6cyl 6A)
On normal acceleration at about 1800 rpm there is an engine noise. The dealer service mgr and factory rep have heard this noise and say it is a piston slap due to phenolic piston skirts. I wrote the company and they agree but say it does not effect the engine. Maybe not but it effects my hearing as I have to turn up radio not to hear it. I am sorry I traded in my M35 for this car.
