We have had our Sonic LTZ with 1.4L and automatic for just over 3 months now and have close to 8000 miles on it. So far no problems whatsoever. We are a retired couple (67 years old) and feel comfortable in this car.
Gas mileage has been very good with 38.7 mpg reading on the car display and we also check it the old fashioned way and get similar results.
It is a fairly quiet car depending on the road surfaces- some coarse pavement causing noticeable road noise but wind noise is low even on the interstate highway.
Handling is good but as one or two reviewers mentioned potholes or certain road irregularities can cause some darting.
The best part is I can fit my convertible car seat, a infant car seat and still fit an adult in the back seat (traveled 150 miles like that today) The fuel seems good but i'm not sure, i went on a 2 hour drive today an back, an used almost 7 gallons of gas, i was pretty upset with that. Backing out of my drive way, whenever my tires go down the front of the car hits into the drive way, it does that on alot of people's out where I live... not much i can do about it, but they are really low to the ground.
It's a great car , but we will see as the time goes on. Oh and the throttle is horrible!
Words cannot adequately express how much I love my car!
I had been driving the same vehicle for over 14 years. And I decided that enough was enough. It was time to get something different.
And it was the best decision that I have made in a very long time!
I brought this car new with 3843 miles on it. I left the dealership only to discover that there was no heat. Returned to dealership and found coolant low. It then took 8 times in shop and from Nov 14 2014 till Jan 12 2015 to find a factory defect. And now it leaking again with the dealership having no idea where. Make sure you have the Sonic checked before buying.
Ive had my sonic for almost a year. Ive had to have the radio replaced twice. People can barely hear me through the Bluetooth system (I have a Galaxy Note 3). The car idles weird now and theres a rubbing sound in the back end. This car feels very unstable on the highway and the dealer says there is nothing wrong with it. I went on vacation and someone smashed my passenger window open and the alarm DID NOT go off and GM says it will only go off if the door is opened. So far nothing major has went wrong and I'm hoping it stays this way. I will be trading out as soon as I can. I would not recommend this car to anyone.
