The driver's seat in the MDX is stuck in the highest position for the front part of the seat BOTTOM. There are 3 motors for the seat bottom. One moves the seat front to back, one moves the back of the seat bottom up & down (tilt), & he 3rd one moves the front of the seat bottom up & down (tilt). The seat will go forward & back, & the rear seat bottom tilt will go up & down, but the front tilt is jammed in the full up position. I can feel the motor trying to work when you hit the switch, you can feel the motor torque over just a bit before it stops, like the track is jammed or something. I unbolted the seat so I could tilt it up & back & inspect under it, but could not see anything obvious to fix.

I've never even heard of anyone working on something like this. I'm sure Acura's solution would be to replace the whole seat undercarriage for a massive parts & labor bill.
Anyone heard of or had this problem? Any ideas?

 

Check the fuses under the dash. I had an issue with mine and it had a blown fuse. I replaced it and it's been working for about a year now without any issue.
