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?

While driving on the highway late at night, at approximately 60 mph my 2012 Sonic began to lose power and slowed to a dangerously low speed when there was nowhere for me to pull over! I literally had to coast to a spot that I could barely squeeze off the road! Then would not shift into any workable gear but 1st and after that just revved up loudly. Long story short…had to be towed 35 miles home. Then towed to a reputable garage where they concluded the transmission was shot at about 90,000 miles. Would be around $3800. to rebuild. Come to find out these cars are known for this problem! And yet somehow I’m being told by GM that it’s not included in the Turbine Shaft Fracture Recall for that car’s year/make/model!! WHY?! Needless to say….the car will be junked!

Engine 2

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.

01.24.2023 Purchased Chevy Sonic 2012 three weeks ago (12.27.22) w odometer at 33,688 and manuf. date of 03/2012. It has multiple recalls, inc transmission, that GM has reported resolved. I have had to schedule a transmission rebuild for $3,200.00 in February. After pressing on gas pedal, the vehicle hesitates as though it is going to stall, then lurches forward. On open road it will buck. When slowing down to stop or make turns, it bucks and lurches. The problems duplicate those stated in almost all of the complaints reported on this site. If GM has reported this vehicle as properly repaired, then I am stuck. Also, the questionable low mileage of a ten year old vehicle and dates of the recalls make me wonder about where and when or if all the recalls were truly resolved. There is one accident reported on this vehicle, Sept. 2022; was the accident caused by the same powertrain related problems?
