Was so happy after bought a 2011 MDX Base model on Saturday, however discovered a problem the very next day that it would jerk when decelerating from 35~40MPH to around 15MPH without breaking. The jerk is 100% reproducible and getting worse and worse. Brought back to dealer twice and finally convinced them it is problem that need to be fixed. Eventually they figured out that a secondary valve on the transmission is faulty! How could this happen on a brand new car?
After replacing $200+ part, the problem is fixed. My new car has to stay in the shop for 3 days in the very first week. Really worry about the build quality. It will be my last and final MDX.
