Transmission will not shift into reverse or shift out of 2nd gear

- Acworth, GA, USA

The car got stuck in 1 gear while driving on a highway and then would not go in reverse. Took it to the garage and was told the transmission wave plate has broken. This car has only 70,598 miles on it. Has been serviced regularly. I did a quick google search and this is a huge problem with these models! there was a recall for the same problem but doesn't include my vehicle.

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

My car jerks when it downshifts. It's been doing this about a year after I got it. Got it checked out at the dealership and they said it's not a problem. Fast forward...it's worse. The car jerks in second and first downshifting. Doesn't matter if I'm driving on the interstate or city street.

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. Afterwards, I couldn't get the car to move above 1000rpms and reverse gear went into failure. The tow truck couldn't move it without placing it into manual mode. It's been in the garage for a week with all diagnostics showing failure within the transmission. At this point, I either need to replace the transmission or buy a new car. I only had approximately 55,000 miles on the car in 7 years.

While driving on highway the transmission made a noise and just stopped. It is exactly what the recall states! I could have written it myself. Thankfully, got over to the side of the road without incident. GM states this VIN is not part of the recall. Certified Chevrolet dealer's "diagnostic" is "black fluid with metal in it" (more of an observation) and they will not take transmission apart to determine if it was indeed the turbine shaft fracture. Of course, they just want to put in a new one at my expense. GM should want to know if there are more Sonics with this issue to extend the recall and keep people safe!!

- Island Lake, IL, USA

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. The car cannot get out of it's own way.

Button on the shifter occasionally sticks. When it happens you cannot get your key out and you can easily accidentally go into reverse. After checking online I've come across several people with the same problem. This is definitely a safety hazard

In the summer of 2017 the check engine light came on in my Sonic and the car would not accelerate. It would even happen at red lights when I would come to a complete stop. After turning the car off and having it sit for a few seconds, it seemed to be fine. In September 2017, it was unable to pass inspection because of this. I was told it was a problem with a hose in my engine and had it replaced. The car ran fine during the winter. In spring of 2018, when the weather started to change, the issue of the car stopping and failing to accelerate came back and began to occur. It is the same issue that I was having before and I am very concerned about this in terms of safety. I have attached a copy of the service expaination and receipt.
