4 Power Train problem

Failure Date: 12/30/2023

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!.

6 Power Train problem

Failure Date: 01/24/2023

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?.

8 Power Train problem

Failure Date: 09/17/2022

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.

9 Power Train problem

10 Power Train problem

Failure Date: 11/07/2021

Driving 2012 Chevrolet Sonic approximately 50mph, car down shifted on its own to 20mph nearly getting rear ended. Tried driving in auto transmission and manual mode, transmission stuck in 3rd gear. Had to drive 11 miles on busy road at 20mph, speed limit is 50mph. Car is at dealer, has turbine shaft break and wave plate broken. Because car has 1-2012 on sticker, no warranty is available. My option is $4800 to replace transmission or junk it. Car only has 93 thousand miles and was always mainted very well, lucky there was no injuries.

During stop-and-go city traffic, the car will struggle to change gears, and has (between 5-10 times) "stopped responding," meaning that the car is unresponsive to pressing the brake or gas, although the electrical system continues to run. The only solution we have found to this is putting the car in park, turning it off, and turning it back on again, but this is very scary in the middle of traffic. This happened most recently on 5/8/21 but has happened at least 5 times in the past 18 months.

18 Power Train problem

Failure Date: 06/27/2020

At 94000 miles the car stopped shifting period. It would start and then go nowhere not forwards backwards nothing. Thank the lord I was parked at my house and it was a sudden occurrence.

20 Power Train problem

Failure Date: 05/30/2020

I was experiencing issues with the transmission on my vehicle. I lost control and when it stop abruptly in a ditch after hitting a fallen limb of a tree the airbags did not deploy. Since this incident I have extreme pain in neck, dizziness, and weakness in both my arms. My vehicle is not listed as part of the recalls and the violent stop of my vehicle upon hitting the object was severe enough to snap both tierod ends yet airbags did not deploy. I have significant injuries as a result and a wrecked car that I feel was hard to control due to the problematic acceleration of transmission.

Failure Date: 10/19/2019

The shift lever button will not release when in park, so the vehicle doesnt not read that its firmly in park; the key wont release and I cannot turn off the vehicle until the button unjams itself or I lubricate it to do so. This has been happening frequently. The only fix is replacing the entire shift lever, which is upwards of $300.

24 Power Train problem

Gear/transmission failure while driving in steady traffic. . . Car suddenly went to 5-6000rpms without pressure on the gas and then down quickly to 1000rpms before I was able to stop and pull over.

28 Power Train problem

Failure Date: 05/05/2019

The gear shift in the car started sticking about 3 years ago but it would still shift so I wasn't too concerned. Since then it's gotten gradually worse until tonight where it took me 5 minutes to put it into park. I couldn't released the key or get it out of reverse and it was terrifying. Mine and others safety was put at risk because my car not going into park means it can roll anywhere and cause an accident. I haven't taken it to a dealer to get checked and it hasn't been inspected by anyone else. There never have been any warnings from the car that there is an issue.

The car has under 100k miles and seems to be having transmission problems. Everything has been well maintaintanced. I recently purchased the car being the second owner. The car has issues getting up to speed causing people to tailgate me or speed up and go around me. You can also feel/hear the transmission going through the gears. The takeoff is absolutely terrible. You can tell the engine is working hard. The rpms don't go above the danger zone but they do rise when switching through the gears. It's very likely to cause a accident especially on the interstate.
