I'm the administrator for VerticalScope Inc's Infiniti Q60 forum. I'm the original owner of a 2017 Q60 Red Sport 400 with 36,xxx miles which shares the VR30DDTT with the Z. So the wastegates on my turbos occasionally rattle during cold starts since new. During my last scheduled maintenance (12/2022) which happened to be the month when my factory warranty ended, I asked that the turbos be inspected as we've had Q60 forum members report turbo and engine replacement. The service writer asked if I was hearing any noises from the turbos. I mentioned what I thought was waste gate rattle during cold starts. The turbos were inspected and then replaced under warranty. The new turbos still have the occasional waste gate rattle under cold start, so I don't know if the original turbos were actually defective.
Anyway, I'm looking to eventually trade in the Q60 when a decent amount of 2023 Z model inventory hits the Houston area.
Are there any known common issues with the 2023 Z?
