2017 CX-5 with 37K; Driving on interstate yesterday at 70-75 mph and all of a sudden "down shifted" 4 times and I could not accelerate out of it. Almost felt like it was falling out of gear but would not respond to acceleration--traffic behind and traffic beside me as I tried to get to shoulder. This all happened in about a 15 second time frame and then corrected. It felt like I was being hit from the rear--kind of a jolt. No messages popped up on the computer so I am not sure that the dealer will be able to track it down. Ran fine for next 50 miles to finish trip---anyone experience anything like this?
