2007 Chevrolet Cobalt: engine knocking or ticking

Filed Aug 16, 2017 · Steering · 68,750 miles · AL

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.

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.

Noticed that the car turn signals were working, but there was no ticking sound inside the car. Noticed that the front left speaker went off and on. When it worked, the turn signal sound would return after going over a bump, but then stop working again. Then the right front speaker stopped working. Learned that all audio warning devices in the car are connected to the front speakers. If a child in the back seat removes his or her seat belt, there is no auditory signal to the driver of this danger, same if the car door is opened, etc. Contacted gm last week and they said they would help with repair costs, which I had done at their dealership, but now they are saying I was given the incorrect information from their consumer office and they will not pay the almost $200 bill to replace the speakers. This is a safety issue as all auditory warnings come through the front speakers of this car. Also I was never notified of a recall for a leaking gas pump or even the existence of this problem in this make and model.

Strong smell of gas when im driving the car in and outside. The car has trouble starting, I had it checked and was told there was a fuel leak. Called gm and was told even though their was a special coverage for my state they would not fix the leak. This is a dangerous leak due to a faulty plastic part. I hope my family doesn't die from inhaling fumes or blow up. Kinda makes you think its another pinto exploding gas tank deal. I guess they wont do anything until someone dies. I have had many problems with this car starting a week after I bought it new. Knocking when the engine starts, using oil now, airbags not working, small electrical things keep going wrong. When I take it in im told they cant reproduce the problems.

My 2007 cobalt drove fine,until it reached 55000 miles. One day it felt and sounded like the front end was going to fall out. If I would go slow over a hump,you could hear a knocking noise at the bottom of the steering column. I took it to 6 different mechanics, who checked everything, struts,springs, rack & pinion,etc. Finally,one mechanic,turned the steering wheel left to right about a 1/2 an inch and you could hear a knocking. He said, take it to the dealer, it is the steering.I made at least 10 trips to get it worked on. I was on the phone daily with gm. I explained when I am driving down the road,the car is all over the road,they think I am drunk, it does what it wants to. The steering wheel turns way farther than a normal steering wheel,alot of play. I can park and the wheel will be upside down,but my tires will be straight. Or driving straight and wheel is turned to one side. I was soo upset, mad, because this is a 2007 vehichle. I knew nothing of a recall.they replaced my 2 front lower control arms and my lower steering column. I had to pay $900.00 for all of the work. It fixed my problem about 60%.the dealer was so nice and understanding, that he reimburse me. Which I am soo thankful. So I haven't even bothered to get back intouch with them. I am to the point that I do not care. If I wreck, I wreck. I am tired of all the hassling, time, money, aggravation and days on the telephone. I still hear a knocking going over a small hump. I drive slow, stop at railroad crossings,because I try to take care of my car. I have always bought chevrolet and have never had this kind of trouble. I really do hope they figure this out and they probable do to. They are not allowed to sale any cobalts off the dealer lots at this time,until it is resolved. I am sure it is not all cobalts with these problems. I believe atleast 50% of the people have heard or read of these steering problems and are saying that theres does the same thing. I just know that I would hate to be in gm's shoes right now. Thank you.

Tl*the contact owns a 2007 chevrolet cobalt. The contact heard a noise as if metal to metal were knocking together in the front end of the vehicle, especially when he hit a bump in the road. The contact noticed that the failure had become progressively worse since he purchased the vehicle in may of 2007. The dealer installed new brakes pads and turned the rotors; however, the failure continued to occur while driving various speeds. He took the vehicle to the dealer 7 times and the most recent was february 2010 when the dealer replaced the two front struts. The failure has not recurred since the front struts were replaced. He called the manufacturer and was instructed to take the vehicle to the dealer. The current mileage was approximately 49,000. The failure mileage was approximately 900.

Not long after I bought my 2007 chevrolet cobalt (on labor day 2006), I noticed that occasionally there's a noise in the rear of the car which sounds like someone is knocking on the trunk. I took car to dealer and they could not duplicate the situation so they said there was nothing they could do about it. I've had numerous people in my car hear this noise and ask me what it is.
