2006 Chevrolet Cobalt: engine overheating

Filed Oct 7, 2014 · Fuel system · CA

Gas leaks from top of gas tank, can cause fire, and throttle switch causes engine to loose power, I have had it cleaned and it works, but now I have second cobalt, and it does the same thing with throttle switch causing car to run under 20 miles per hour. The power reduction can cause engine to overheat and the leaky gas tank can catch fire. Someone should look into this issue asap.

Hydraulic cylinder went out on an 06 chevy cobalt with 42,000 miles on it. Was driving it less than 15 MPH in a residential complex on level ground when the clutch went loose. Could not shift and had to roll it into park. Both hydraulic cylinders were replaced (spent $1400 so I'm assuming they were new parts) and now the clutch sticks and the car is overheating. Still waiting as to what is to be done with the new problems.

On february 26, 2010 as I was driving my 2006 chevy cobalt the power steering quit functioning. I could not steer the car. The message "power steering" appeared on my dashboard. I took the car to a local mechanic. The mechanic stated he received complaints from other cobalt owners about the same problem. On 2/28/10 I called chevrolet customer service and reported the problem. I asked if there was a recall and told the representative what I was told by the mechanic. The chevy representative said there wasn't a recall at the time. I told the representative that I did not want my relatives to have to sue the dealership because I had died due to the power steering failing while I was driving my cobalt. The representative scheduled an appointment with a local chevy dealership to inspect the problem and said I would have to pay a diagnostics fee. On 3/2/10 the power steering malfunctioned again as I was driving. Fortunately, I did not have an accident. Coincidentally, when I went home and turned on the television I saw on the evening news that chevy cobalts were being recalled for power steering problems. I am leary of chevy dealerships. I purchased my used 2006 cobalt in 2008. It had 36,000 miles on it. Soon after I purchased the car I noticed the engine kept overheating to over 240 degrees. I took my car to a chevy dealership three times about the engine constantly overheating. They told me it was due to the plastic radiator overflow bottle leaking when it expanded when warm. They replaced the plastice bottle but the car kept overheating. Out of frustration I took my car to another repair shop. The other repair shop discovered that the engine overheated due to a cracked manifold. The chevy dealership failed to identify this after three visits. I have also had to replace the gear shift after 36,000 miles and a bushing at 69,000 miles. I am curious as to what they will say about the power steering failure at my appointment next week.

Correction to odi 10315929. Mistype about engine overheating - the engine overheated due to a cracked head gasket, not a cracked manifold.

I have a 2006 chevrolet cobalt ss. Back in january I had an incident where I was driving and the message center on the dash displayed "power steering." once that appeared and chimed, I lost most manueverability of my vehicle and it became hard to steer. Once I got to my destination, I turned off the vehicle and back on, and noticed that the problem did not replicate. At the time, my cobalt had approximately 78,650 miles. Since then, I had not had any occurrence until 2/1/10. Since 2/1/10, the problem occurs every day. It seems to occur after approximately 40-50 minutes of driving and then my power steering kicks out. Turning the engine off and back on will correct the problem, but within 5 minutes the "power steering" message reappears. The engine has to cool down for the length of driving time to increase. I drive a 44 mile commute daily one way, and experience this every day; seeing that I am not the only one experiencing this, it poses a serious safety risk especially when most of my commute is highway driving. I've had it kick out when I'm on an expressway exit ramp almost unable to continue my turn around the corner. I have seen that gm stated in rebuttal to this investigation that "if it goes out it requires extra effort." being a fairly burly male, that extra effort is a lot! It is like you're going against quite a bit of resistance on the power assist components. I used to work for ups and drove their trucks; their package cars don't have power steering and I know how the lack of power steering feels; this is nothing in comparison. Just having a major snow storm here in the midwest, it poses additional safety concerns trying to maneuver on snow covered pavement. Another concern and question that can be posed, is that if it cuts out after approximately 40-50 minutes of driving, that may mean the power assist is overheating. Can that cause a fire in the vehicle? My cobalt now is close to approaching 80,000 miles.

The powersteering on my chevy 2006 cobalt 4 door, the powersttering light comes on, then the car is nearly impossible to control. Makes driving almost impossible. Took to mechanic, seems the computer chip is ok, the selad system for the steering fluid is ok, it is an electronic motor that overheats is what the mechanic stated. Repaired 2/2/2010.

2006 chevy cobalt loses power steering while driving. I had just gotten off the highway and my car lost all power steering. Took it to a shop the next day and they said there was a bulletin out that these electric motors can overheat if you car sits idle for too long or you are stopped and the wheel is turned a certain way. It was a very snowy day and the roads were very icy. There would have been no way for me to swerve quickly out of someone's path if they cut in front of me or god forbid a deer would have jumped in front of me. I have a 6 year old daughter and thank god she wasn't in the car. I would hate to get in a severe car accident because there is a defect with a chevy part. This should definitely be recalled and fixed immediately. I imagine there are several parents that have this car and how unfair is that? I was told to just shut my car off and let it cool down. Well that's a fabulous idea on a highway when the roads are icy. Good idea. I should have thought of that. This is a serious malfunction that needs to be fixed.
