NHTSA Complaint #11681157 — 2023 VOLKSWAGEN ID.4

While accelerating and decelerating, there is a low popping noise that comes from under the floor of the car. It sounds like metal reacting to a change in temperature when it pops, like if you pour hot water into a metal sink. This has been a consistent issue for over a year, and despite the dealerships attempts to fix the issue by replacing the sway bar and tightening the suspension and upper and lower control arms, the noise persists during acceleration and deceleration. The dealership was able to reproduce the issue when we have taken it in. There are no warning lights associated with this issue. If this issue is related to the battery or to the breaks, it could be a serious safety problem. We've taken it in for this issue 4 times and we'll take it in again this week, and the dealership has held the car for over two weeks total to try to fix it.
