I was going about 75 mph on the express way with one lane open due to construction. My car started losing power.I heard the chime and upon the dashboard were the words power reduced. My car slowed down in a matter of seconds to around 45 mph. A 18 wheeler was trailing behind me. I quickly jumped in the emergency lane to my right and took the next exit while riding the emergency lane. I shut the car off at the gas station, sat there for about 10 minutes, restarting my car helped temporarily. I was 3 hours away from home and had to drive back unknowingly if I will make it or not. I reached out to Chevrolet and was told to bring it in and leave it but they had no loaner cars for anyone at that time. I have replaced 2 sensors and now my start /stop has quit working. I spoke with 5 visitors at Chevrolet and we all were having the same issues. This is something ongoing according to my research on this particular vehicle and should be recalled asap.
