Are cobalt ss reliable

How many miles a year do you drive? Multiply that by the years and add it to 120,000. If I were to buy a 5 year car I would go with something with a LOT less miles on it.

12,000 miles a year after 5 years would mean your car has 180,000 miles on it which is pretty high even if you take really good care of your cars.

No they are not. tons of youtube video's of people trying to fix these things, the engines are junk. Yea when running the first few months make good power and are fun to drive but by then they are useless.

They are good cars as long as you know what you are doing I have 5 of these cars and they are amazing

Code po 302 is a nightmare and a regular problem.
