There is a button on the transmission gear selector that allows the selector to move from park to the driving gears. On my car the button is now sticking in (will not release) this cause the gear selector to move freely from one gear to another such as drive to reverse ect also as this in in the in or engaged position the key cannot be removed. This is a safety issue as the car can be placed into reverse and or drive just by touching the gear selector

The contact owns a 2012 Chevrolet Sonic. While driving approximately 65 mph with the gear shifter in drive, the transmission downshifted into second gear. The vehicle then decelerated to 30 mph, jerked back and forth with a loud unknown noise, and then went into idle mode. The contact coasted the vehicle to the side of the road. The vehicle was towed to an independent mechanic (lowell automatic transmission in MA), where it was diagnosed that the turbine fractured and needed to be replaced. The vehicle was later towed to the dealer (lannan Chevrolet located at 831 rogers St, lowell MA, 01852) where it was diagnosed that the transmission shaft failed and needed to be replaced. The vehicle was not repaired. The manufacturer stated that the VIN was not included in NHTSA campaign number: 14V315000 (power train). The approximate failure mileage was 125,000.

The contact owns a 2012 Chevrolet Sonic. On several occasions, the gear shifter failed to operate. The contact stated that the shifter button would depress, but not release. As a result, the vehicle failed to shift gears and the key became difficult to remove from the ignition until the shifter button was released. There were no warning indicators illuminated. The vehicle was taken to the dealer where it was diagnosed that the shifter needed to be replaced. The vehicle was repaired. The contact mentioned that he previously had the shifter replaced twice; however, the failure recurred. The manufacturer was notified of the failure, but did not offer any assistance. The failure mileage was 52,956.

Gear shift release button has been slow to release for some time and recently cracked in half. That left me unable to shift gears out of park. I repaired with glue temporarily but would like a permanent solution from the manufacturer.

Transmission recall14V315000. My son and wife were driving in freeway traffic when suddenly, the vehicle lost speed and would not shift into third or higher gears. The vehicle speed was limited to about 25-35mph. It was a very frightening experience which could have caused a crash as my son was trying to weave out of high speed freeway traffic. The failure is related to a broken wave plate in the transmission which prevents 3-6 gears from engaging. The symptoms experienced are very similar to a recall GM has on some 2012 Sonics where the vehicle has limited speed and won't shift past 3 gear. Research reveals there are hundreds, if not thousands of these transmissions with the wave plates breaking and posing a safety concern.

Car started misfiring when accelerating and would jerk and be very rough when idling but no engine light. Full tune up found that open valve cover gasket was damaged and that seals were plastic when they should've been rubber, this caused oil to enter the spark plug wells. Changed gasket and seals but problem persisted. Took to the dealership and was told that ignition switch in cylinder 1 was bad, this corrected the issue but now car has burning smell at times.

Know to shift gears has a button your press to change gears. At around 44000 miles it gets stuck everyday. It pops back out eventually, but it's a dangerous hazard. Surprise it hasn't been recalled yet, with the many complaints I have seen.

Shifter button is sticking (will not release) which prevents removal of the key from the ignition. Also, could allow the the vehicle to be shifted into other gears (park, reverse, etc) while in motion.

The button that is depressed to put the car in and out of gear sticks in place, allowing for the gear shift to be pushed out of place. I have had trouble numerous times getting my car into park because the stuck button causes the gear shift to get caught in reverse, and today I accidentally pushed the gear shift into neutral while sitting at a red light.

Air intake hose has been replaced due to cracking only 3 years old at that time about 45K miles. Now the shift knob sticks and the button takes forever to release, or I have to pop it back out so I can take the key out otherwise the key gets stuck. Getting worse...now it is becoming harder to shift into park. All these problems occur when stationary...I have not attempted to move the car into other gears while in motion but I know it will happen if it is pushed while that button is not released.

Once again my check engine light is on. I have had this car since 2013 with 16000 miles on it. The first time the check engine light came on the dealership try to tell me it was the gas I was using. Come to find out it was the air intake hose was cracked....that was a little over a year ago and now it is on again!!! the first it was barely covered under warranty, I dont think it will this time. I am pissed.....I paid 17000 for this car and have had in the shop so many times it isnt even funny. I even had it in for the sway bar link that was broke which shouldnt have been at 42000 miles.
