My cobalt illuminates the check engine light as well as the theft light and displays engine power reduced happens multiple times first time it started was in 12/2017. The car was purchased in 2011 always serviced and repaired by dealer ship. The car stalls at stop signs lights or when you pull into a parking lot. Engine light comes and goes. Lights dim and flicker the gauges jump up and down in the dash. After you shut the car off the gauges in the instrument cluster jump adn make ticking noise. When there is no engine light present the car idles rough and acts like its going to die till you start driving then its fine. The issue with the brakes are when you to press them the pedal will depress all the way but its like it dont meet with the pad, this problem is intermittent as well. Obd2 codes have been p0641 p0017 p0651 p0573 current codes stored are p0340 p0300 p0341. I've had this car at the dealer and multiple shops on multiple occasions now without resolution. It's becoming more of a problem than anything especially when your on the interstate and it dies or coming up to a stop light/ sign, a car pulls out or an animal and your brakes fail to stop you! It is a very scary situation. The car does have high miles but I have not had any problems till december of 2017 mileage is 203,602 all maintenance is performed under recommended mileage.

Vehicle developed at rattling noise in the steering column when driving over rough road surfaces. I believe it is related to a plastic gear inside the column that others on the internet have described. Recently it has developed into a very loud rattle accompanied by a loud knocking noise that is heard and felt in the steering wheel only when braking moderately. Light or heavy braking seem to not cause this, so far. I am concerned that the problem may eventually result in the failure completely of the steering column. This would result in the inability for the electronic power steering motor to assist in turning the wheel, and thus the loss of control of the car. Or I am afraid it could result in the complete loss of steering all together.

When the vehicle is in motion on a city street and on the highway, the power steering light comes on, all indicators (I.e. Fuel, coolant etc.) go down to zero (says "low fuel" when tank of gas is full) and there are ticking sounds from the gear shift area. There is a loss of power to the car at the same time. There is a recall on the 2007 chevrolet cobalt, recall number 10v073000. The power steering module was replaced in approx. 2009, at our expense.

The vehicle lost power steering today in traffic. The dealership said the power steering recall was performed I'm march of 2011. I had the vehicle in for a knocking noise previous to this date (2007). Nothing was ever found. I found out today that the knocking was related to the power steering. I ignored the knocking because I cant afford for the dealership to find nothing. This is a recall that was never fully corrected. I feel as though gm ignored the real issue. I still have knocking noise and now, loss of steering.

Car was recalled in 2010 for power steering. Previous owner had it fixed. I initially reported back in january 2014 of recurring problem of losing power steering while driving. I was told it was already fixed so I would have to pay out of pocket to fix same problem as the recall. Here it is a year later and I'm still having the same problem with the power steering. The speedometer started flickering back and forth going haywire and there was a weird ticking noise in the area near the gearshift. I had to pull over on the side of the highway and was almost struck by a tractor trailer because the power steering locked up on me and I had my 3 kids in the car. I was told that I needed a new coil pack, it was replaced and it's still doing the same thing. It shakes at red lights and occasionally cuts off. I have to press the pedal to the floor to get it to accelerate which it does but very slowly, and then it just takes off like a rocket and I have no control over it. This is very dangerous!! Also my car can switch gears without having to press the brake or the button in the gearshift. I can just simply push the gearshift back and forth without being in the car. While backing out of my driveway my kneecap bumped my keys and my car turned off. There needs to be another recall of the power steering because apparently the replacement parts are faulty as well. Or it could be the faulty wiring altogether in the system. These chevy cobalts need to be taken off of the streets and owners reimbursed for the car plus all of the trouble and near death experiences that we have to continue to experience on gms behalf. I have read several other complaints about the power steering being fixed and still have the same results as myself. How many people will have to die or another lawsuit presented before there's another recall to have these cars removed permanently off the roads?

I took my car to a repair shop after hearing a strange noise while driving to work. After an analysis, I was informed that the engine had no oil in it and the noise I was hearing was called "engine knock." I was also informed that the engine was completely shot due to lack of oil. My oil light on my dash never came on to alert me of any problems with my oil. When I start my car, the oil light along with all the other emergency lights (I.e. Traction control, check engine...) light up as usual and then go off, so I know the actual light works but I think there may be a sensor issue.

My 2007 chevy cobalt is making knocking when I let off the gas, go over bumps, or just set in the car. I have taken my car to a mech and they told me its my sway bar links and my strut/shock is leaking. How in the world can a sway bar link fail under normal driving conditions and not that very many miles on the car. It looks as thou I am not the only chevy owner with this problem. Gm needs to fix this serious issue! I know I cannot afford to fix it.

Car has a hard yank after coming to a stop and starting off. Knocking noise coming from rear of car since day one of purchase. Vibration in accelerator and gear shifter. Lights on interior of car dashboard goes on and off. Problem still happening today and the tsm was replaced as well, as they always say they cannot duplicate the problem. Check engine light has never came on at anytime the problem happened. It happens after car is driven and heated up. Only happened when long trip over 50 miles, now since ignition has been changed on call back. Problems has worsened lights on and off, transmission hard shift when driving short trips as well as a constant vibration. Knocking coming from gas tank side of car was mainly during cooler weather now happened when day was above 90 degrees. Electrical problem with vehicle I think and has caused many problems and even deaths. Do not think it was keys ignition. I seriously think is in the entire electrical system. Problem should of been fixed when 1st reported, but they only reset the trans computer.
