When accelerating from a stop (as in turning from a stop sign into a lane with oncoming traffic) to merge into flow of traffic the automatic transmission shifts up normally but then suddenly downshifts into first gear causing rapid deceleration creating a situation that may cause someone to hit the rear of my vehicle. This has happened 5 times so far. After the first time there was also a check engine code and the dealer replaced a transmission sensor. Since the 1st time (with just over 100 miles on the brand new car) it happened 3 more times without the check engine light and after shutdown and restarted it would operate normally. The 5th time (2 days ago) it happened again almost causing an accident with another vehicle and the check engine light stayed on, I went slowly straight 2 the dealer (1 mile away at the time). It is still at the dealer. This has all been on city streets. When this occurs I tied the manual function on the shifter and it still wouldn't shift.
