2012 Chevrolet Sonic engine problems

Filed Aug 20, 2026 · Body, Brakes · IL

I purchased a 2012 Chevy Sonic with 65k miles on it from Carvibe LLC earlier this month. When I took it into Firestone for a full inspection, they found that the car has severe rusting to the mechanical parts along with the body of the vehicle - the entire structure of the vehicle is compromised. Someone spray painted the rust black but Firestone was still able to see the covered up rust. Firestone has deemed the vehicle unsafe to drive.

I purchased this car 2 years ago and it has caused me absolutely nothing but trouble. We have replaced the fan 4 times (twice due to the resistor thats part of the fan failed), headgasket job, intercooler punctures (once inward, once outward), failed valve cover, intake maniford, turbo seals twice, failing check values, new relays for the fan (twice), another drive belt, and now I go outside and theres a puddle of coolant under my car. I have sunk over $8,000 into this car and it has been the worst financial decision ever. Why do the parts keep failing? Why isnt there a heat gage in the dang car so I know its too hot before the light comes on?

We have had to deal with severe overheating issues and failing parts our entire ownership of this vehicle, both of which then cause other parts to fail, as the parts are so poorly made and heat sensitive. We have replaced the turbocharger (twice), intake manifold + valve cover (twice), catalytic converter, the radiator (THREE TIMES), the cooling fan (twice), the MAF sensor (twice), and much more. All of this has been done over the course of 18months. This has easily been the most expensive car we have ever owned due to the constant repairs, all of which has been because of Failing Parts and overheating.

On 4/1/2023 my engine light went on. I had my nephews look at it. see pictures below for engine read and how oil mixed with antifreeze. Also note service paperwork. Gaskets were not up to quality to keep the oil sealed in its compartment. Manager called and tried to take care of issue because he only uses genuine parts but was told there was an issue with this part and until there were more fatalities or more people complained noting could be done. He was NOT happy. They did the best they could resorting to youtube videos and imagination. When I got it back, it was like brand new. Two days later, my engine light came on again. You will find the new engine reading which again had the oil mix with the antifreeze and no oil left. The engine would blow/seize or worse if I kept driving it. I am on disability and live alone. I cannot afford the unpredictability of having something happen to me on the road or where I am suppose to the money. I complained before to a manager at a dealership when I had a problem with my motor when my car was still new. He told me it was supposed to be like that. I keep revving in the middle of traffic lights and people were on my backend when I would get out of work at 3:00 am. The car was recalled two months later to replace many individual motor parts. I am too old and anxious to play these games. Please seriously have look into this please. Thank you for your time.

A few months after this car was purchased, we received the notice regarding recall 14234 for our 2012 Chevy Sonic. However, when we brought it to the dealership, they stated that our vehicle didn't fall under the recall. I told them we were experiencing shaking while shifting and it seemed like the exact same issue. Now about 1 year later with less than 100,000 miles, the car will not shift properly into 3rd gear. The auto repair shop informed us that we need to get a new transmission among many other related repairs. We seem to have the exact same issue as reported in the recall; however, we continue to be informed that our vehicle does not fall under the umbrella of the recall. After doing a number of searches it seems that this is a common story. All these 2012 Chevy Sonics have the same issue yet do not fall under the recall.
