NHTSA Complaint #11443577 — 2015 MERCEDES-BENZ CLA250

I noticed for the last several weeks my car sometimes hesitates when I start the engine. I hadn't looked into it and wasn't sure what it could be because I changed my battery less than 2 years ago. I hoped it was a fluke or do to the increasing cold weather. Also the car occasionally shudders and hesitates when I increase and decrease speed and one or two the radio shut off on it's own. This morning, the automatic windshield wipers came on even though it was not raining and my windshield was not wet. This lasted for a few minutes before it stopped on it own. Then I drove about a mile and was at a stop light. When I eventually tried to accelerate, I wasn't able to and it was then that I noticed my car had slipped to neutral on it's own. I was on a busy road when this happened. The car also restarted on its own and I was able to shift to drive and continue driving. Thinking this was a fluke or perhaps a battery issue, I continued to drive for a few more minutes and again I found myself at a stop light and again, the car slipped into neutral. I quickly put my emergency lights on and restarted the car. The radio came but on, but I noticed the A/C did not come back on. I didn't bother turning it back on. I was able to drive 23 miles to my destination with no other incident. The majority of the 23 mile drive, after the car had stopped 2 times, was highway driving, so I did not need to stop much.
