Our new RT RS Adventurous

Hi, I won't go into a lot of details, but the same thing happened to us 20 miles into the BlueRidge Parkway in July and we spent 6 days in Fredricksburg, VA with our 2012 RS in the Mercedes Benz dealerrs shop. The engine light went and the transmission went into limp stage. We were towed, Mercedes USA paid for the tow the 70 miles. The next day they connected a loose wire in the transmission that fixed the engine light problem, but another light went on that was related to the electronic module and they thought clearing some codes would fix it. After failing two more times, once after it was "fixed" and we were on our way 45 miles away from the dealership, they ordered the new module. After waiting 3 days (weekend), they droppped the transmission and found metal in the pan. They had to completely replace the transmission. Completely blew a hole in our vacation, as we rented a mini van, emptied the RS, and traveled 850 miles back to Michigan. Dealership called at the end of the week, and we drove back to VA a week or so later to pick up the RS. Suggest they check the module, and have it replaced before you travel any distance. Still in negotiations with Mercedrz Benz USA on some reimbursement for hotel stays and cost to drive back to VA and pick up the RS.
