I was driving to my sister's house on sept. 27 2020. When my car started making a loud noise from the engine and I noticed the engine light came on. I pulled over called my husband, when he got there he opened the hood and noticed the catalytic converter broke completely off my engine. We managed to get to a friends down the road for the night until we able to get it towed to the dealer's the next day. When I called the and told them what happened they told it was my fault that I must of hit something to make fall off. I do not have any other underneath my car, I tried to tell them this was a safety issue and that I could have possibly burned to death in my own car if I hadn't of pulled over upon hearing. . . Thankfully I was in an area where I could pull over. I did call gm also they to said it was my fault and or weather conditions. I told them it was not my fault I did not hit anything and weather have nothing to do with it, bottom line is that part should have never fallen off to begin with. Because it did fall off I felt it should have been covered under warranty on your website I noticed you already have a primarily investigation going on this matter complaint # pip5419b.

My car just reached 79,000 miles and I was driving when my car cut off in the middle of traffic! this happened twice in the same drive. It immediately started back up but then the check engine light came on along with a stabilitrak error message. Then a message saying engine power is reduced. Now the car's engine is making a terrible noise and is having problems accelerating without making a loud sound like air trying to blow through a pinhole. The chevy service department I took it to wants almost $700 just to take it apart to see what it wrong with it, which doesn't include the possible amount for repair. And they did not look at any of the technical service bulletins like requested! now they are saying my car is not able to be driven at all. I went online and started to research these issues and found that there has been a lot of complaints about these exact issues most even the same year. There is no reason that a car with 79000 miles should have engine problems. I owned a 2003 Impala prior to this one and had almost 125000 miles before I purchased this 2011. There are way too many complaints going on with this car for it not to be recalled.
