NHTSA Complaint #11452396 — 2016 ACURA TLX

Was driving down interstate 70 at approximately 75 miles an hour. My cruise control was set and I was going up a small hill and out of nowhere my car decelerates down to about 50-60 miles an hour and it won't shift into gear/turn over and is making a grinding/revving noise. Almost all of the warning lamps and messages started flashing when this happened. There were cars behind me and next to me on the interstate when this happen and could have caused a serious crash given that the car decelerated and stopped functioning in the middle of the road. I had to pull over on the side of the interstate and I immediately called the dealership to see what was going on and if the car was safe to drive. I took my car to the Acura dealership either that same day or the next day and they claimed they didn't know what the issue was and told me that they reset the mainframe and that would take care of the issue. It did not take care of the issue and this problem has continued to happen multiple times. With the most recent time that this issue occurred they told me that I needed to buy a new battery and that would take care of the issue. I purchased a new battery and 2 days later the same thing as above happened again while driving 75 miles down the interstate the car decelerates and about causes me to crash. Prior to this situation happening in 2020, there was an issue with my battery and when my car would go into idle mode at stoplights/stop signs, it would die in the middle of the road and I would have to wait a few minutes before it would start back up.
