36 Engine And Engine Cooling problem

Failure Date: 11/27/2014

My wife was driving on the highway and it felt like transmission was slipping . We have a 6 speed manual turbo chevy Sonic. While the car was under the 36000 warranty an engine fault light came on and we brought it to the dealer. I believe they said it had to do with turbo ? they repaired the fault and now at 50000 miles it appears the transmission has let go and/or clutch ? recall 14234 appears to be what happened to our vehicle or the aforementioned turbo problem they worked on and want us to pay for something that maybe a recall item or faulty workmanship during warranty period.

For about a month now everytime I go to park my car my shifter get stuck and I am unable to put my car in park or take the key out. I went to the dealer ship and I was told I could spend $150 to get it looked at & then spend how every much money it would be to fix it. I dont have that kind of money for that at the moment but now its to the point where I cant even drive my car at all because the shifter always gets stuck and I cant get my key out to park or put it in park drive reverse etc. . . . . . ! ! ! I have seen that a couple people are having this problem so its not just my car. But since it gets suck I can be driving down the road and hit the shifter by accident and it will move the car into another position because it dosnt click witch means I can go from driving to it being thrown into park or reverse in seconds. Thats going to cause a accident! I need this fixed I drive with kids in my car on a daily basis . . . . . . . . . . Their is something wrong in the shifter.

41 Engine And Engine Cooling problem

Failure Date: 09/30/2013

I brought my car in because there was something wrong with the steering. I asked that an oil change be done and when I picked it up the car had white smoke coming out of the engine and had a strong burning smell. There was a lot of smoke I was only gone 10 minutes from the dealer before I had to bring it back. Brought it back dealer said they smelled burning and sprayed a deodorizer in vents to mask it, but they did not address the smoking that is still happening. Filed compliant with gm requesting a buy back of vehicle. I bought the vehicle the first year it was out,and have also had multiple issues with the front end, air conditioner not to mention that the dealer dropped car off rack and caused damaged.

42 Engine And Engine Cooling problem

Failure Date: 06/06/2013

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.

43 Engine And Engine Cooling problem

Failure Date: 04/28/2012

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 area it runs even crappier like its going to break down right in the street. I have the 5 speed, and its a terrible car!.

44 Engine And Engine Cooling problem

Failure Date: 02/04/2012

I turned on windshield wipers & the engine died. This was the first time it had rained after I bought the car & really did not at this time associate the wipers & the engine dying until later that same day when contacted a friend of mine to drive the car. The dealer contacted gm about the problem but they don't seem to be very concerned about the problem. The dealer replaced the wiper motor but that did not solve the problem. It is a long story & I'm very concerned for the safety of myself & others. It died the other day in traffic when it started to rain & I turned on the wipers and almost was hit by a truck. Please contact me, it would be easier for him to explain in person about the problem.

46 Engine And Engine Cooling problem

Failure Date: 01/01/2012

A few months after purchasing my 2012 chevy Sonic, I've noticed a decease in power and hesitation in its automatic shifting between gears. I've taken it in several times with the same issue, and each time the service techs (even the service manager) has told me and explained that it is behaving "normal" and "to design". If it were "normal" why hadn't it done that driving right off the lot??? and why is it, years later, its shifting hesitation has gotten worse to the point of severe jerking as it shifts from one gear to another, as if someone were learning how to drive stick for the first time?????? there is nothing "normal" about how my vehicle is performing. It is complete bullshit that I've been getting the run around about this issue for years. And they refuse to admit there's a problem, nor will they service it, which makes my vehicle ineligible to be claimed as a lemon, which it obviously is!!!.

47 Engine And Engine Cooling problem

Failure Date: 12/01/2011

When I am driving on city streets and am behind a car that is turning I have to slow down. When I give it gas at around 2k rpm. The car has some hesitation like it cant find a gear to be in. It has done it seance about 100 miles. Has 7000 miles on it now. Was told it was the transmission trying to find its shift points as you break it in at 1000 miles. (berger chevy) also when in garage and start car it sounds fine. But once I put it in rev. I hear lost lot pings coming from the engine area. Started after deer crash. Took to berger chevy where car was bought. They found nothing but just body damage. Hood, front end, and passage side all replace. With 600 miles on car.
