Here's what I've dealt or am dealing with:
- CSC/Master replaced
- Transmission replaced twice
- Both seat belts replaced (wouldn't retract well)
- Power steering rack (might replace again as the new one is also making noise after a couple of months)
- Axle clunk (will resolve in a few months when replacing rear tires)
- Heater core noise (still some air bubbles causing car to overheat in 100F ambient)
- ECU whine (too lazy to deal without having to unlock and reprogram)
- Brake switch (finally replaced after dealing with throttle lag and hesitation for years)
- Driver side window rattle (haven't fixed)
AFAIK, nothing related to running the car with turbos. It's a pain, but the list of these issues is much longer than the '03 350Z.
