1 Power Train problem of the 2018 Lexus GX460

Failure Date: 01/01/2020

There is a thud that occurs in the drive train when accelerating from a stop, or accelerating from a roll. The dealer said its normal, but it cannot be normal. It is a literal thud. I have heard this thud countless times over the last year since we bought the car. I have also read on many forums that other people have this same issue.
