The 2013 Chevrolet Sonic has been a very reliable car over 160,000 miles with very minimal problems. I currently use it to commute over 100 miles a day and the seats have remained comfortable and the heater and air conditioning is working great. Even with the high mileage, the vehicle gets nearly 34 miles per gallon on normal 87 octane gasoline. The interior isn't high class but it's held up well with minimal squeaks and rattles although the plastic does scratch easily and the carpet quality isn't great. I have had an issue with the thermostat needing to be replaced multiple times. The piece carries a long warranty and only takes a few minutes to swap out so it's not a major issue, although it can cause the A/C to not work while it's failing.
