So I posted that after speaking with the rep at MB House of Imports, in Brea, I think. The rep was mistaken, and I never got a quote to replace the motor. I had to replace the dc converter which cost $7,000. The issue with mine is the whine that the motor makes. I was told I had to replace the motor and she quote me about $8,100, but that was for the converter not the motor.
It has had the noise for years. I've had the car 4 years, and I never really noticed it until they brought it up, now it seems to be getting worse, or maybe I'm just paying more attention to it.

. I'm taking it to QCCharge outside of SD. There is a link in another post. They were nice, seemed to know just what the issue was (worn out bearings) and quoted me $4,250 to fix it. They are the only place I can find. Found no place in L.A. willing to work on it.
