My 2013 chevy sonic developed ticking sound shortly after I bought it at 60000 miles. The ticking got worse over time and then check engine light came on. I scanned the codes and multiple four codes were found. P0171, p0496, p1101, and p2270. After doing some research it seemed to be that most cruze, sonic, and trax vehicles all had the same issues. I took it to the dealer for diagnostics and was informed the vehicle needed a new intake manifold, purge valve, pcv hose, and valve cover. They called the dealership to see if there were any recalls and the only one was the valve cover but would have to pay for diagnostics to see if they would cover it or not. The breather diaphragm in the valve cover goes bad due to a fault intake manifold on these vehicle models. There is a little orange gasket in the manifold that goes bad and causes the diaphragm to go out resulting in having to replace the entire system. The intake manifold not only causes ghat issue but causes the car to get jumpy at stops and stalling out. Have almost had a few people rear end me due to this. The purge valve goes out as well and when at the fuel pump the car will hesitate to crank or run at very low idle shutting off multiple times before it starts up and then runs rough until a decent amount of fuel has ran through the engine. The car would not get enough fuel when at stops or on highways and would also just lose fuel and cut the engine off. Those components have since been replaced by myself and no more issues. Chevy will not recall the parts that are causing the issues and therefore there is a safety issue when out on the highways.

My sonic had the same issue as the federal safety agency recall no. : 19e-064, manufacturer recall no. : n192223230. Except, it happened when I reached to use the wipers rather than hitting the key fob with my leg. I reached to use the wipers and my arm hit the key fob, knocking it into the next position, turning off the engine. It could have just as easily moved over one more and locked the steering. The recall was done on the camaro's, so why wasn't it done on any other vehicle using the same key fob and ignition replacement? Was it because the camaro's price is 4 times the price of a sonic? Are camaro drivers more valuable than sonic drivers? There is a class action lawsuit including the camaro recall, but not the sonic. Https://www.gmignitionswitcheconomicsettlement.com/ I reported this back in 2014, and never heard a word about it.

Air intake system. Not long after we bought the car the check engine light came on reading a code ph171. We were told it was a knock sensor which we replaced and it didn't fix the problem, after we were told it was the air intake hose, checked it and it looks like it's a new hose no issues with it. Now we are trying everything we can to figure out the problem. We check online forums and found out that this is a huge problem with this car and almost no one knows exactly what it is to fix it. When the car is driving it seems fine but as soon as you stop and it idles it seems like it wants to die and almost has a few times. Was just curious if this is such a huge problem that so many people are having why there has not been a recall?

I just hope that it is not to late for me and my family.
