In 2011, I bought a Sonic 2012 who turned out to be absolutely faulty. The first problem was with the braking, which did not work or did whenever it wanted to. It was then found that some hoses that control the emptiness were damaged. Later, the ABS began making a terrible noise like the one of an old car. Finally, it started jerking because something in the transmission was failing, and even two times a little engine of the air conditioning gate broke down.

When engen gets a bit hot the check engen light and abs light will come on at the same time and flash for a short while and then goes off again we have replaced the air intake senor and spark plugs but it still does the same.

RPM up and down if car is stoped and sometimes it goes off. If driving its ok but if u want to stop at traffic light suddenly RPM goes from low to high and the transmission will jerk to change gear unless u continue to press brake than it will not jerk. Also engine light on and ABS comes on and off if ur stopping at the light wether ur using break or not.

When I brake there is a a funny sound

For example, when I'm walking and I use the brakes to change the speed, the engine turns off.

When The engine is running, the ABS light fleshes ON at the cluster then car won’t Accelerate or Rev

We bought our Sonic 2012 ltz in 2011 and, since the first year of usage, we've been having problems with it. First, a joint was released and it makes it sound as if it were an old car. It then started failing when braking forward or backward and it ended up being the vacuum hose of the ABS brakes. This year, the stabilizer bar's screws have been replaced as well as the automatic transmission's oil lock. Last but not least, a week and a half ago, we suffered a collision from the front and the air bags were not activated. There is no way we can now feel secure when stepping on the car. If somebody has had similar problems, I would appreciate it if you let me know and if you know how I can solve this. Thank you for the comments.
