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.
