At approximately 60,000 miles the vehicle had just been serviced and new tires were installed. We left the next morning for a vacation. About 100 miles down the limited access highway and traveling at 65 to 70 miles per hour the dash and information touch screen began flashing and a chime began repeating. The windshield wipers began operating at high speed. (it was clear, calm and about 65˚ f. Different messages began flashing: one said to stop and place the vehicle in park, another said to keep driving and not turn the engine off. When able to exit the highway the Jeep would only allow selection of drive or neutral. It would not allow reverse, which made it difficult to turn around. The vehicle did make it back 100 miles to the dealership but would not shift and lights flashed and chimes dinged the entire way. The dealer informed me that an electronic system associated with the transmission has failed and will cost approximately $1,000 to replace.
