This is going to sum up NNA's response:
- Orange Peel - It's normal.
- Throttle lag - It's normal.
- Car won't start, steering lock failed. - Take it to dealer to get it diagnosed. Pay to replace the known good battery. Replace ECU. Then later realize there's a TSB for steering wheel lock.
- Oil recommendation - Use Nissan's ester oil.
- Noisy valvetrain - Use Nissan's ester oil.
- CSC failed, lost clutch pedal pressure. - Take it to dealer to replace CSC and/or master cylinder. Possibly end up replacing the clutch disk.
- Loss of power, high oil temperature. - Take it to dealer to get it diagnosed. After a few trips, get NISMO oil cooler, but voids warranty.
- Intermittent throttle response. - It's normal. Take it to dealer to get it diagnosed. Replace battery. Replace other things. Then realize it's a faulty brake switch all a long.
- High pitched whine. - After being told to make several trips to the dealer, finds out noise coming from ECU. Replace ECU.
