This is probably a new one...anyone have trouble with a squeaky driver's seat on an R51? The sound seems to come from inside the seat back, when you accelerate or push your lower back backwards in the seat...I believe that it's the lumbar support. It can be prettly loud sometimes and gets really annoying.
Took it to Nissan today and they said they'd order the parts, but it sounds like they have to pull the seat and really disassemble it to get inside. 35,150 miles, so I just got it in under the warranty. I'll post any new findings after they do the work.
