Three weeks prior, I had just repaired the rear differential bushings and when I drove of the dealers service lot, I realized the vehicle was dragging and difficulty accelerating which it was not doing before the repairs. I did not drive the vehicle much thereafter until December 29, 2015 as I was driving and came up a stop light, the "Service Airbag" sensor light came on, stays on, vehicle stalls and stops. The vehicle will start but will not move on drive or reverse. I towed it to the same dealership and 6 days later, till today, they still cannot figure out what the problem was. Just today, they called and said, it might be the transmission. Just frustrated and seeking a reliable suggestion.
