Every cold start the is a grinding and rattle noise that comes from the timing side. I took it to chevy and they said that cant do anything unless they hear it which I thought was reasonable and the next morning they called and stated my car has no noise even tho this happens every cold start. I also have a loud knocking noise coming from the engine when it is warm or has been driven for more than 20minutes the dealer says its normal but at 21454 the noise is 3 times louder than ever before. I had a check engine light code p0011 intake camshaft position timing -over-advanced (bank-1) which I took in and they fixed it 4days later and it is back same code I called the dealer and they said to bring it in I explained I don't have a ride to work they said I have to figure it out because I have to pay the deposit for a rental I shouldn't even need. The engine also seems to sputter and lose power randomly also the rpms will go up to 2500 sometimes while stopping I have always drive. Manual transmissions I believe I would know when I am pushing the gas! Chevy seems like they don't want to touch my car until my warranty is out I am so disappointed by their actions and this car sad I got 4 of my friends to buy them too in 2013 I just want chevy to buy back my car or fix all of it! This is my first american 100% brand new car and I feel like it is the biggest mistake I have ever made. The whole we cant just cant look at it unless we see or hear it is kind of bs!

I have a 2012 chevy sonic lt automatic with the 1.8 liter. The car started having problems around 45,000 miles and has gotten worse over time.the car on cold start ups has a grinding sound. This grinding most of the time only happens on cold start ups but does at times happens on warm start ups. This sounds like metal against metal and it rattles. This seems to happen until the car is fully started and running. I am getting concerned because it is getting worse and louder.

The rumbling/rubbing noise began on the passenger side of the front end of the car. With only 3,000+ miles on the car it was still under warranty and was taken to the service department. They found a leaking rf strut and noisy mount and replaced both parts. The replaced part seemed to remedy the rumbling problem but the front end still seemed unforgiving when it was driven on rough pavement. We began hearing a groaning/ rubbing/ grinding noise when the car was turning corners or while turning on an incline especially to the right and at 8,000 miles we returned the car and the service department said it was operating okay. The noise continued and at 13,000+ miles we returned the car and the service department found the mount to be binding on turns and replaced the rf strut mount. Again, the problem remained and finally a service technician rode with us and heard the noise and agreed that it was not supposed to be there. So at 15,000 miles the car was in the service department for two and a half weeks. They replaced the rf strut and mount because the strut was not setting flush in the mount. During the time the car was in the shop the technician called and said they were able to fix the issue but there was still another noise they heard and they needed more time to work on it. We requested a ride along with the service technician and the noise was absent on turning right at a slow speed but very apparent now in the front end of the car when turning in to park at the service department. At that time we requested to speak with the service manager and are in the process of negotiating a deal for a different car as this seems to be an on-going issue. We loved the great gas mileage and sporty look but the suspension seems to be troubled.
