On my way to work noticed the car lacking some power when accelerating to get on highway. Over the next 2 weeks car started sounding different. (like driving with air breather off) while changing oil today noticed air intake tube is cracked. Which could allow dirt and moisture to bypass filter and go into engine causing damage. Now the car has 52130 miles on it 2013 Sonic ls. Air intake tube should last longer then 2 years.

While driving home, the vehicle started to smoke. The windows were rolled down, the air conditioner was off and it is about 86 degrees outside. This isn't the first quirky incident to happen in this vehicle. I just bought it about 7 months ago. All the standard maintenance has been done to this vehicle. Not sure why it is smoking. After it being in our care for 4 months, the check engine light will also not go off, and the remote start doesn't work anymore. The driver side door has become loose as well. No one has been hanging on it, just simply opening and closing the door. Also the plastic cap on the shift has popped off. I will be getting it checked tomorrow and possibly getting rid of it sooner than later. This is a very poor GM model car.

This has happened more than once since I bought the car in October 2013, but it is happening daily now. I put the key in the ignition and it will not turn at all. It is stuck. I take the key out and put it back in and try to turn with no luck. Today it took 15 times of trying to turn the key and taking it out and putting it back in before it would start. I have even videoed myself trying to start my car so I can show the dealership. I am supposed to take it in tomorrow.

After haselwood Chevrolet Buick GMC dealership fixed the transmission seals I noticed that the engine is idling rough when at a stop light I notice this every once in a while.

- Bremerton, WA, USA

When in park, the engine idles very roughly. As a result of the rough idle, the fuel economy is not as good as it is supposed to be. Twice, the car has stopped running when at a stop sign/traffic light. When I reported to my dealer, the dealer informed me there was a tsb on the issue and the solution was to run tier 1 gasoline in the vehicle. The dealer indicated that GM does not have a "fix" for the problem. The car has the 1.8 L gasoline engine with six speed automatic transmission.

When car is stopped, it begins to make a rattling noise, at times it can be quite loud, it also starts to vibrate and almost cut off. The noise sounds as if it is coming from the engine. The noise has been sporadic. I took the car into the dealer and they could not find anything wrong. This is quite concerning.

Jan.7/2013 heard suttle/scraping/rattle sounds, thought I rolled over something on dark road in construction zone. Moved my car to left then really scraped on something. By next morning some oil leaked out. Had car towed to G.M. dealer. They had main engineers trying to figure out what was causing oil to spread in engine &Sonic was insanely smoking black smoke in, around.like in black cloud with sparks coming out back of car. I got terrified, as I had just picked it up, was told they had fixed the oil leaks. Dealer still has car. 3/3/13 they told me it was fixed, but it reeked with toxic fumes, I became nauseous, throat was scratching like before. Told GM that Sonic was not fixed. Requested new car from them. They are offering me a repurchase. I don't know what that means. They have refused to extend my rental to Transport my family of 5 safely.

When stopped at a red light, stop sign, the A/C will stop cooling and blows warm air out of the vents. I went to the dealership and do not know how to fix the problem. Told me that the mechanic/technician could not find anything wrong. The dealership is no help and I just want my 17000 car ac to work normal/ right. 2013 Chevy Sonic 2lt model with a 6 speed auto transmission. Please help thanks!

Per tech notes "case [xxx], advised a normal operating characteristic of 4 cylinder engine. Compared to similar vehicle made the same sound. Was able to deaden noise by applying pressure to front bumper.*** - tech comments: Normal operating characteristic - internal" information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

This condition happens during first drive of the day or after the vehicle sits for a while. While accelerating through the automatic transmission the car surges/jolts at or near the shift points. It almost feels as if I started moving the vehicle in the wrong gear, if it were a manual transmission. This condition also exists if you start moving the vehicle forward and then remove your foot from the accelerator pedal and coast. This vehicle is the rs model equiped with the 1.4 liter turbo.
