CarComplaints.com Notes: The 2012 Chevrolet Sonic is fairly new & is already showing an early trend of transmission problems.

Owners report hesitation when shifting & grinding/hard shifting into gears. Some dealers are calling the condition "normal". Another owner reported his dealership replaced the transmission under warranty, but the new transmission had the same exact grinding problem. Design defect?

On June 19, 2013, after picking up my 5 yr old grandson from summer camp, we were on our way to the park. I am driving approximately 45 mph and all of a sudden, my grandson opens the door! while the locks engage when put into gear, he was able to open the door! needless to say, I flipped out! that's not supposed to happen! my doors are supposed to be locked!!! I find this very dangerous and unsafe for anyone, any age! my car does have child locks, but why should I have to turn them on every time someone gets in my car when my locks automatically engage when put in gear!!!!!"????????? Chevrolet has always been my favorite make of a vehicle and that is why I chose to buy one. Plus, the Sonic was a wise choice for me at the time because I was driving 60-75 miles a day back and forth to work and home. Then more traveling on the weekends to mobile, al to visit family. After that incident, please mark my word, that I will never buy another Chevy again, and I will make sure that no one else does as well. I will contact my local news station and hire an attorney, if I have to, make Chevy improve my vehicle or give me something else that is safer for my family! what if something were to happen to my grandson? then what? what if it were you and your grandbaby or son or daughter? you best better believe that you would have the biggest lawsuit on your hands that you've ever had to witness!!! and I guarantee that you still will have one, if they don?T make this right! I am not asking for money (that?S not what I"M about), but simply another vehicle that is safer than the Chevy Sonic and to make all Chevy Sonics safer!!!! I am appalled that Chevy would make a vehicle that is so unsafe!
