This car overheated and a head gasket blew. I am on a Facebook forum, and it seems like all of these cars have these problems. The Chevy Sonic ltz turbo 1.4 2016 is known for coolant issues and head gasket failures. My car only had 104,000 miles on it. It should last a lot longer than that, but this is a common issue. For some reason there was a recall but they stopped fixing cars with 1.4 engines that came out after 2014. There cars don't have temperature gauges and when they overheat they don't tell you until a light comes on the dash and by then it's too late and your engine is blown. This should be illegal. Chevrolet needs to fix this.

Radio malfunctions. Channels automatically change and touch screen doesn't work all the time. I believe 2015 Sonic has a recall for this issue , but not 2016. It appears to be the same issue.

My car lock and unlocks when I did not hit any buttons. The remote start does not work sometimes. The battery loses connection from time to time with a brand new battery.
