rotors had to be smoothed out due to a bit of shakiness on highway braking - rotors are fine, but had some 'bumps' on them. This is something I saw a lot of when I had the G35x prior to this M45x. I think it's a weakness in Infiniti brakes.

Low frequency vibration at 20-60 mph was not solved by rotating tires so it is probably the DS wheel bearing. Mechanic wants to let it get worse to confirm which bearing is bad. Driver's seat moves forward/backward by 0.25" during hard stops/acceleration. There's a TSB out there apparently. Otherwise, the entire seat base needs to be replaced at ~$1200.

Replaced front passenger-side wheel bearing. Cured low frequency vibration noted earlier. On an intermittent basis, the A/C and fan can take 2-5 minutes to turn on. Sometimes, the system works for 30sec and then stops for a few minutes, no rhyme or reason. Mechanic replaced the blower motor and resistor, which helped somewhat.

Dealer replaced blower motor relay (same as earlier repair done by my indy mechanic) to fix intermittent A/C delay issue. Turns out that it may be a short or loose connection in fuse box causing all of my issues. Dealer adjusted fuse box. Seat rocks forward or backward during hard acceleration or deceleration. Automatic steering wheel position function only works 50% of time upon entering vehicle. Dealer wanted to replace entire motor assy, which I declined. Forum indicates that it's probably a cheap sensor that needs to be replaced.

Works perfectly now. Moonroof continues to leak since it was brand new. Infiniti worked on front driver side door following a very minor accident. Less than one year, the door began leaking. Took no responsibility, so I would not pay them to fix a problem that they caused. To date, leaks have caused moisture build-up on back window, causing bubbles between the glass and tinting.
