NHTSA Complaint #11562870 — 2014 CHEVROLET VOLT

I bought my car and I had no idea about a known issue that this car has. Unsuspecting and trusting, I noticed my car had a reduced propulsion and it would like lose power and just slowly jerk and then really drastically reduce speed without anyway to fix it and on the freeway I got scared as I have never in my life has this happen in any car. So it happen a couple more times and I took a picture of it and took it to the dealership where I purchased it. They told me they couldn’t do l as they can’t repeat the issue. Well that only usually happens when I’m driving but now it’s more. The propulsion thing loses power and I as a driver going up a hill or anywhere now will lose speed and it’s dangerous, I feel like I may not make it home and I took it to the dealership many times and they told me there’s no issue. I took it again recently now that I’m out of warranty because it also had some high voltage issue and a sensor coolant issue that misreads. I like the car but very unhappy about dealership and manu not fixing this issue that every volt owner I talk to has, read about. I lose power, my car randomly heads up when it’s been cold all night and not driven now I have the same issues. I have the same issues and I use 91 gas, I have inspected my car and I had to learn about cars or more than I ever did which was like zero all because of this car. I even took it to the dealership 3-4 times (documented) to get it fixed and they just said there isn’t anything wrong nor did they say there’s a known issue and watch out for this or that. I had to look up the issue and learn about it on my own. Very dangerous date happening this is happening now almost everyday but was frequent 1.5 years ago but last 8 months it’s like the standard. I’m afraid my car will lose power on freeway, which it does and I have to take toll to stay away from others for everyone’s safety
