Infiniti M in California, United States Dec 2011 - Sep 2015
Feb 2012 90900 mi	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.

Dealer wanted to replace entire motor assy, which I declined. Forum indicates that it's probably a cheap sensor that needs to be replaced.
