2012 Chevrolet Sonic owner complaints

Vehicle stalls when pulling out from a stop, and/or at low speeds when the clutch is pushed in. Then, it takes three seconds before the car can attempt to be re-started! Very dangerous when turning left across a highway or into traffic, especially since there is what seems to be a 'programmed' waiting period of 3 seconds before you can attempt to re-started. I've owned this vehicle (1.4l turbo engine with 6 spd manual transmission) since 05/21/2012, and over 8,000 miles later, it still stalls every time I drive it. The dealerships say, "cannot reproduce. Operating to specifications." *tr

The clean air hose from the throttle body to the clean air hose split at the convolutes causing an unregulated air / fuel ratio and lack of power due to the engine running lean. Potential safety issue if accelerating. Mileage at the time of failure 77,791 kilometers (48,230 miles)

The console gear shift has a button that must be depressed to shift. Button sticks in depressed position. Cannot remove keys in park position. The button broke I had to replace the whole console gear shift and have it installed. There needs to be a recall on this issue.

Tl* the contact owns a 2012 Chevrolet sonic. The contact stated that the transmission became difficult to shift and hesitated to respond. The vehicle was taken to a dealer where the technician diagnosed that the turbo transmission needed to be replaced. The vehicle was repaired however, the problem persisted. The vehicle was taken back to the dealer where the technician stated that the valve, transmission fluid and a gasket needed to be replaced. The vehicle was repaired but the problem recurred. The vehicle was taken to the dealer a third time but was not diagnosed or repaired. The manufacturer was notified of the failure. The approximate failure mileage was 34,000.

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

Tl* the contact owns a 2012 Chevrolet sonic. The contact stated that there was a strong hesitation when the vehicle was in first and second gear, as well as when the vehicle was in motion. The vehicle jerked excessively without warning. The vehicle was not included in NHTSA campaign number: 14v315000 (power train). The vehicle was not diagnosed.

The contact owns a 2012 Chevrolet Sonic. The contact stated that while driving approximately 55 - 60 MPH, the vehicle hesitated to accelerate. The failure nearly caused a collision. Upon investigation, the contact related the failure to NHTSA Campaign Number: 14V315000 (Power Train) however, the VIN was not included in the recall. The vehicle was taken to the dealer and Della Chevrolet of Plattsburgh (5101 U.S. Ave, Plattsburgh, NY 12901). Both dealers informed the contact that the VIN was not included in the recall. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 60,000.

Checked car while stationed, when running always needs more cooling maybe electrical burnout of a part that connects to the radiator fan. When put the diagnose code, none is given, and temperature goes up to 225, its a hazard if a person does not know that fan is not working, putting refrigerant all the time. Read that there is a new re-design cooling fan assembly.

Idles roughly, idle increases dramatically while the car is at a stop, and the engine stalls very frequently, regardless of temperature or weather conditions. On start-up, or while stopped with the engine running, the idle will become rough and vary between 200-3,000 RPM, but not stall. Also at times, while stopped, the idle will increase from normal, smooth idle up to about 3,000 RPM for approximately one second, then drop back down to 750 RPM (normal idle speed) without touching the accelerator. The engine will also stall at parking lot speeds when I push in the clutch to shift from 2nd to 1st gear. The car also often stalls when pulling out from a stop. A re-start cannot be attempted for approximately 3 seconds. Turn the key, nothing happens. I've owned this vehicle (1.4l turbo engin

Radio randomly turns on when car is shut off. Last night it turned on 13 times. It activates the full electrical system in the car. Won't shut off unless car is started and xm radio is tuned to fm and shut off. Then if your lucky it may stay off. I have been reporting this to the dealership in vermont and Chevrolet for 8 months. They tell me it is not an issue. They tested radio said it works fine. It is worse when cold out. Radio randomly turns on. Will not shut off. *tr

There is no heat in my 2012 sonic, the heat is turn to the highest position but only blows cold air. Occationally the heat will start but when the car is not in motion there is no heat and only cold air.

First of all the windshield wiper line keeps popping of my car not allowing me to use my windshield wiper fluid so the tank is always empty. Second while driving my car radio flickers on and off and sometimes completely goes black not only that my car speedometer is electrical and after 30 min of driving says im going 20/34/whatever MPH it wants to read when im really going the hwy speed limit and I have often had to mess with the wires that run to my battery to turn my car back on since its the wires(electrical work and not the battery) my battery has been tested many times. Finally third the little shift button on my car keeps sticking and wont allow for my car to properly shift causing my car to over rev and not want to drive. Im now at 115,000 miles and every time I go to a dealershi

Car will start by itself after key is partially inserted into ignition and car will try to start over and over if left in ignition when turning off. Took to dealer they blamed on aftermarket radio. However, I am pretty sure has done almost from the point purchase. Disconnected radio stuff and still does same thing. Car is stationary in park. No safety issue other than what is stated.

Tl* the contact owns a 2012 Chevrolet sonic. The contact stated that the vehicle would hesitate to accelerate over 10 MPH. In addition, the vehicle stalled when idling and the check engine warning light illuminated. The vehicle was taken to an independent mechanic, who diagnosed the unknown parts needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was unavailable.

This car when sitting at a idle shakes it don't matter if you start it up in the morning or in the day or night. It acts like it has a misfire when driving like all the cylinders aren't working properly. Taken to dealer twice since I bought it new in march 2012. Has a rough idle everyday ,after it warms up and you drive where ever you are going and then sit at a idle it bogs down,shakes the car. And im tired of going through this the dealer says its normal . And that the tech guys say its there number one complaint! Im upside down in it so im stuck unless I can maybe file the lemon law.the dealer told me the first time I went that it was the alternator from sitting overnight. Lol really??? And that the Chevy trucks do it too. Come on....and if the car has 3 or less bats showing on the gas

Tl* the contact owns a 2012 Chevrolet sonic equipped with hankook optimo tires, size: 195/65/r15 (n/a). The contact stated that she took the vehicle to the dealer for an oil change and noticed that there were bubbles in the front driver's side tire. The contact stated that she contacted the dealer and but they provided no assistance. The vehicle was repaired however, the failure later occurred on the rear passenger's side tire. The failure mileage was 9,000. The DOT number was unavailable.

This vehicle has had "undiagnosable" problems aince it hit 1200 miles. I have made 57 visits to Chevy dealerships for attempted diagnostics and repairs. The car has lurched forward of its own accord, my brakes have failed to engage on a single occasion, the car has intermittently shut off during idle, the car has also had issues with shifting for the last 2 years. A 3 year battle has yeilded no answers or improvement; I was unable to utilize the lemon law because the issues couldn't be diagnosed. Finally the car is showing codes for what I believe is the transmission based on how poorly the car is running. I can provide information for the dealerships I have worked with; they have all the documentation for the obscene number of visits I've made with this car.

While driving at highway speed on a two lane road at night, applied brakes to avoid animal in road. Conditions were clear and road was dry. There was plenty of time to slow to avoid animal so this was not a panic stop. Upon application of brakes, headlights went out. Dash lights stayed on making it impossible to see out of the vehicle. Applied brakes with more urgency and all four wheels locked. Vehicle skidded straight until the right tires made contact with the right shoulder. The car then spun counter clockwise back onto the roadway, across both lanes, and came to rest on the shoulder of the oncoming lane (approximately one and one-half revolutions). Skid marks on highway confirmed the wheel lock and the spin. Car was shut off and re-started and all systems worked fine. Un

I bought this vehicle brand new. Paint started to loose shine about two months ago ( I personally wash the vehicle with properly cars wash soup). Took to dealership and they can't cover under manufacture warranty. Cost over $400.00. Check engine on. Took to dealership and they found two hoses damaged and thermostat leaking.

My 2012 Chevrolet sonic has gotten its second flat tire from alignment issues, and is about to need a third tire replaced. The car has 26000 miles with a clean bill of health, other then major steering issues. The tires completely run bald on the outer edge of the tire, and a shaking is experienced at all speeds while driving the car. I had taken it to the dealership about this issue, but was told it was happening because I am not doing an alignment every 6500 to 7500 miles; which I find to be ridiculous. I have never heard of having to align a car that frequently. So there verdict this far is I have to by all new tires and get an alignment done on my car with only 26,000 miles. I contacted corporate headquarters out of frustration caused from the dealer ship writing me off twice, and say
