I had the VTM-4 light come on the other day on a 2009 model. We took it in to the dealer and were told that there is a Electromagnetic clutch failure on the left side and that we would need to replace the read differential unit. Has anyone else had issues with this? Also, the quote from the dealer was just shy of $4000...ouch. We have taken good care of the vehicle. It has 72,000 miles and we have kept up with all the maintenance.
