NHTSA Complaint #11580948 — 2017 CHEVROLET VOLT

We bought the car for our son when he began to drive. We liked the idea that it was gas and electric. At the time, our son was into electric vehicles. At 44, 000 miles, 7/10/20 the car was taken to the dealership. The engine light was on at this point, the message displayed "Propulsion Power is Reduced". Once the diagnostic was done it was said that the EGR valve needed replacing. Of course, this is during the of COVID. Everything was shut down. No one is working. It is now a wait game. Prior to this our Chevy Volt has been in and out of the dealership with either recall or something else. We enjoy the car because of how it operates with gas and electric. Fast forward it is 80,000 miles now, and the car is at the dealership again. It has currently been there for almost a month. After blowing fuses it has be diagnosed as the EGR valve needs replacing again. The part is not available currently. No one seems to know when it might be available. The part cannot be purchased from our local distributor. GM is the only ones who makes it is our understanding. There is no other dealership near us that has certified technicians who can work on them. We called around and asked. We want to know what the solution is. How can this be prevented? We were over an hour away from home and no dealership was open when it went out the last time. It became worse to the point that we were stopped on the road with flashers on because it was not safe to pullover. Prayer works.
