2012 Chevrolet Sonic: engine knocking or ticking

Filed Feb 15, 2015 · Transmission · 46,000 miles · TN

I have a 2012 chevy sonic and the gearshift will not lock into place and an accidental bump will knock the car into another gear which could be dangerous to me and others. Reading online threads, I have noticed that this affecting many other cars of this make and model. I notice that gm wait until the last minute to issue recalls. I just hope that it is not to late for me and my family.

Beginning from the first month of ownership. Approx. 28,000 mi. At cold start there is a rattle noise like metal on metal. Then will disappear right after. Has been getting worse/ louder. Hard shifts, loss of power. Now as of last night the check engine light is on and the car runs rough. High idle, stalls, knocking noises from engine. Fault code. P0011?

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!

Issues began with an intermittent rattle at cold start after car had been sitting about 30mins to an hr, from being driven. No codes showing so went un-repaired, once pinpointed, it was replicated, still no codes, no fix, starting about aug 2012 after my 1st service car began to shake at idle while stopped in d, started getting worse progressively. Vehicle stalled in middle of intersection while trying to shift itself (auto trans) into 3rd, violent jerk to a stop and immediately picked itself up and jerked forward and moved, with my children in the car. Next stall occurred about 3-4 weeks later, idled so rough and low while in d at a stop light, car bogged down and stalled, started itself right back up. Engine power surging began at this point. While braking or on brake while stopped, engine would power surge thrusting car forward, came very close to hitting several cars while pulling into parking spot from these surges. Had taken vehicle in multiple times between 1st occurrence and this point in sept. It was duplicated with multiple symptoms at once, including as given from dealer: hard shaking, misfire, and rattle/knock at cold start. Only code to show was for the misfire, repair: valve cleaning, not fixed. Rattle became a knocking. Idle meanwhile getting rougher. Took back for knocking, surging, rough idle, stalling. No codes, repair: gm tech assist had camshaft actuators replaced , fixed knocking/rattle at cold start only! Idle worse, now loss of engine power intermittently causing vehicle to hardly move, had vehicle back less than 24hrs. Almost had a "t-bone" accident and head on into a pole in same incident due to said loss of power. Asked for replacement (after 7 service repair attempts), request presently in limbo, no offer of replacement thus far! I am severely concerned for my family's safety at this point, clearly defective in itself with no codes showing.
