Problems with 2012 Chevrolet Sonic POWER TRAIN

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.

While driving my car, the car looses power and began to stall. i've went to two chevy dealerships and two repair and no one is able to tell me what's the 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. 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.

Automatic shifter release button sticking you can not get the car to go into park to shut off car also it stays depressed causing you to be able to easly hit the shifter into neuteral or reverse while driving

Tl* the contact owns a 2012 chevrolet sonic. while driving 30 mph, the vehicle stalled and the check engine indicator illuminated. the vehicle was towed to the contact's residence. the vehicle was taken to an independent mechanic who diagnosed that the turbine shaft malfunctioned, which caused the vehicle to remain in third gear. the dealer stated that the turbine shaft needed to be replaced. the vehicle was not taken to a dealer for diagnostic testing or repairs. the manufacturer was made aware of the failure. the failure mileage was 134,000.

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.

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!!

Car will not go into reverse. car will not shift properly, appears to be stuck in 2nd gear.

Automatic shift button gets stuck causing the ability for the vehicle to accidentally come out of gear. when the shift button is stuck in, i then need to pry the shift button out to put it into park in order to remove the key. we have been driving the car for a couple of years thinking it is not a big deal to pry the button out (rather than pay $400 to get it fixed), until we figured out that when the button is stuck in, it can easily be bumped into different gears by accident.

In 2014 the shift gear was replaced due to a recall. it hasn't been 3yrs, and the shift gear is damaged again. when i shift gear from park the release button stays stuck, posing a safety hazard, if by accident the shift gets pushed while the car is on drive. upon parking the car, the release button stays stuck and the keys will not come off until that button is release.

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.

The button on my gear shift is sticking. whenever i shift gears the button sticks. sometimes it will stick the whole time i am driving and other times it will only stick for a minute or two. what deeply concerns me is when i park i cannot remove my keys or turn my car fully off until the button to return to a relaxed state. sometimes i will have to sit in my car for a half an hour waiting for the button to come out of the gear shift. this has been happening for the past month.

I can be driving my car normal when out of nowhere it almost completely loses power in the middle of the road (to the point it is very dangerous to be driving). the tcs light will illuminate as well as the check engine light with 2 codes. i was in traffic and my car literally would not pick up speed/accelerate (even with pedal all the way to floor). this is a very scary situation that should not be happening with a car that isn't even that old and only just hit 60,000 miles. i'm guessimg on the first date i noticed the issue, and it happened again on september 29, 2017. i do not feel safe driving this vehicle i have invested in and feel my tranny should have been one included in the recall, especially with it failing before 60,000 miles. please help.

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

My chevrolet sonic has developed an issue where the automatic transmission shift lever button is sticking in the 'in' position. in this position, the transmission gears can be changed without touching the button is such a fashion as to move the transmission from park to reverse, neutral, drive and in this module it has a so called manual mode. so one could bump the gear from reverse to drive or from drive to reverse just by touching the gear shifter. of course, with this button in the in position you cannot remove the key out of the ignition. i feel this is a safety issue and thus reporting it as such. this issue can happen both driving and before driving. as it is not safe to drive the car this way i will be taking this in to a chevrolet dealer to be fixed.

I purchase my car march 2012. had have been taking it to dealer about the washer fluid not staying in bottle. they told me nothing was wrong. then took it again for transmission slipping into gear they said again nothing was wrong. now the transmission is not working and they say the recall is not for my car cause there website says so.it stopped moving on the highway with me having a 2year old in back seat. i finally got my fluid to stay in bottle by some other mechanic.

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.

12/23/16, i purchased a 2012 chevrolet sonic. 4/6/17, i was at a traffic light when smoke come in the vents from the hood of the car. i called onstar & to run a diagnostic. the diagnostic didn't return any information & i contacted the dealer & took the vehicle for service on 4/9/17. i was told the thermostat housing was leaking and caused the smoking. the coolant system was flushed & filled & a gm oil, lube, filter change was done. the vehicle was ready for pick on 4/19/17. a few weeks later the car was smoking again. i called the dealer, i was told it was probably just fluid on the engine. the car continued to smoke periodically. 6/7/17, there was a large pool of oil under the car, i took the car to a local shop. they said that the oil had been overfilled & that it blew a seal. i called the dealer, i was told they did not overfill the oil & made another service appointment. i was told again there was a problem with the coolant system & the oil & that was the reason for the smoking. repairs completed 7/10/17. 9/27/17, while driving the check engine light came on, so i called onstar for a diagnostic & they gave me an error code p0299. they told me that it was an airflow problem. i called the dealer & asked for the service manager & gave her the error code. she said there was a problem with the turbo & that i needed to bring the vehicle in. i took the car to them 10/3/17. 10/4/17, the service department called me & told me that the turbo on the car was bad. the repairs were completed on 10/12/17. 10/13/17 the car overheated. the vehicle was leaking coolant in two places. i took it to a different dealer & they said the t-joint in the coolant system was leaking. the repairs were completed on 10/18/17. 11/3/17 an email from on-star said there was an engine problem. i contacted on-star for a diagnostic & they said something is wrong with the coolant system.

Starting in november 2016 the gear shift button began sticking a little on the cold days. a month later i was unable to take the key out of the ignition and couldn't get the button to pop back out until the car was warm. wd-40 helped temporarily and then my mechanic cleaned it and use silicone. it was better but still sticky. no issues during spring, summer and fall but it started as soon as the cold weather hit. if i am in the car long enough it isn't a problem but short trips on cold days mean i have to use a card to pry the button out. only once has it caused a problem while driving when it too easily slid from d into m1. i dropped my car off to have the gear shifter replaced. the part is about $150. i don't know how much labor will be and i havent been under warranty for years.

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.

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. *tr

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.

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.

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.

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.

Automatic gear shift button sticks. shift lever can move from drive to neutral to reverse to park without locking as the button is stuck depressed. keys cannot be removed when car is in park. stationary and in motion. multiple times. situation is getting progressively worse, i.e. button is sticking more frequently.

My trans will not shift passed 3rd.

When car is placed in park, ignition key cannot be removed.
