Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

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?

After purchasing my Chevy Sonic 2012, I went to get my first oil change 3 months later. And the engine light came on. I have gone back multiple times, and have been told that it was the gas cap which by the way had a recall on it. The light came back on a week later. Took it back they said that the one they replaced it with had a bad seal. They ordered the part replaced the cap. Drove for another two weeks and the engine light came back on. Took it back, this time they told me that the car needed a thermostat replacement done the light came back on again. Took it back this time, I was told that it was a air vent tube that was connected to the engine, which by the way is not covered under my power train, did that and yet again the light is back on. Now my radio goes on and off when it wants to. When I get up to go to work my battery is dead. They have also replaced the drivers air bag for some sort of recall. The windshield wipers was replaced as it also had a recall. I really want to trade this car in I am literary scared to drive it. Scared driver...........

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 dealership they say there is nothing wrong with my car when I know there is since I have been the one driving it and then they just give it back to me which still costs me money with no solution my cars state has just been getting worse and worse and due to limited income I cant afford to get a new one at this time otherwise I would have already traded this Chevy pos in. I also called Chevrolet's corporate office where the lady gave me a case number and never called me back like she was supposed to. While on the phone with her she told me that there was nothing she could do for my car since my car wasn't a recall but I find it odd that my car was made on February 28, 2012 which falls between two major recalls with problems similar to what my car has especially since one is the windshield wiper recall. So I believe that the Chevy corporation as a whole doesn't want to take responsibility for their faulty car that they have made and when you take it to a Chevy dealership they will continue to tell you nothing is wrong so that they just take your money and not fix your car. Unsafe&immoral.

I was driving at night and it was warm outside.....so bugs caked onto the windshield. When the bugs caked onto the windshield I tried to use my windshield cleaner and nothing would come out and I ended up smearing the bugs. I absolutely could not see....so I made it to the nearest gas station and checked the reservoir to find it empty. I went into the gas station and bought a cheap bottle of clean and put it into the reservoir, and as soon as I put it in a puddle drained from underneath the car. I found that the reservoir could not hold the liquid and I figured that a hose must be loose.

I went to go some place when I noticed the passenger side of my windshield cracked. There is no chip indicating that something had hit it. The crack seems to have started from the edge of the windshield. It seems that the windshield had twisted. The crack is approx 8 to 12 inches and circles into an up side down U. I believe GM should look into this problem. I have checked to see if GM has a recall and they do not.
