Sonic LT 1.8L

  • Manual transmission

I bought this 2012 Sonic car new in Oct.2011. This has been the worst new car I have purchased (new cars owned:Tahoe,Sonata,Accord LX,Altima,Tacoma,and Accord EX). This car has 31000 miles on it and the Thermostat housing has a leak and I have had the Transmission repaired under warranty for not shifting gears. There are Product of China tags on wiring harnesses and parts of the engine! I thought this was a American Union Autoworkers Company! China ! Well this is another example of inferior American Engineering and Corporate Greed at its finest.

Thank you Obama for spending my tax dollars on the GM bailout. I'm really reaping the benefits of a Quality company and product. I had at least 40000 miles on my new Hyundai Sonata before mechanical failures. Guess I will trade this in on a reliable Honda before it completely dies!
