| First off 10,000 miles after my warranty ended the clutch went on this car. since then i have had to replace the clutch 3 more times, replace the transmission and then rebuild the transmission. whoever at chevy decided to use atf in a manual transmission care due to their own design flaw of a smaller whole thereby creating synchos which were not properly lubricated should be shot. so here we are again for annual transmission maintenance..ie: the clutch went out again. this time we changed it and since all the frame bolts were stripped out from the liscensed mechanic who did it the last 3 times, we had to take it out the top. next came the new starter that had to be put in and now it is all back together, all fuses checked out ok, the battery is ok, the starter checks out of, but....the car will not start. dash lights indicate that there is a power steering issue and i am out of gas, both of which are incorrect so something is wrong and i am out of ideas as to what on this stupid car that i never should have purchased and will never purchase again because it is junk!! | |||

| Battery died in car, had to jump the car. car started fine, steering seemed to be a little tight. after a few minutes of driving the tightness in the steering went away. however upon arriving at home the key would not come out of the ignition, and the shifter would shift into any gear easily without having to press in the shifter button. also in attempts to remove the key the steering wheel is now locked all the way to the right with the wheels locked in the right position. was able to remove key from ignition by locating the emergency key release switch under the steering column but car will not start now as key wont turn all the way, and shifter still shifts into any gear without having to press the shifter button. car was parked front first against building so i have no idea how i will get it towed out of there to a shop to fix it! i suspect the shifter cable assembly at the end of the shifter which is made out of plastic is broken. will verify when its taken apart. i have seen at least 50 other cases on the internet where this piece breaks and causes the car not to register it being in park and will not release key from ignition. gm recalled certain years for shifter problems but not the 2007 unfortunately! *tr | |||

| Purchased vehicle brand new in 2007 and no problems till now. 22 year old daughter driving vehicle, she is a college student. she drives in major city daily and driving home from school gauge cluster went crazy and power steering went out. scaring her, she parked the car in a church lot and i sent the car to a dealer the next day. i had found on the internet that there was a recall on the power steering assist motor and informed the dealership of such when the work was to be done. they replaced the motor under the recall but also charged me $780.00 to replace the steering column which they said was bad. i have found 1000 + complaints on the internet of people saying their steering columns were supposedly bad as well with 1 person having theirs replaced 3 times now. she picked the car up and 2 weeks later the same thing occurs again. the dealership looks at it for 4 days and claim they can't find anything wrong so do nothing but investigate. they claim the codes were erased on the computer because we drove it after the fault but the car was parked and immediately hauled to the dealer on a flatbed truck. as i said before there are well over 1,000 complaints on the internet that i have found myself so i am sure there are a lot more. as soon as i can afford it this car will be put in town square with a big lemon sign on it and she will be driving something other than gm. | |||

| The power steering of my 2007 chevy cobalt went out nov 27, 2009, late at nite on i-95 - freaked me out and caused me to be stranded! no dealerships service dept. open on weekends, so i gave up and drove it back to florida on sunday (took 10 hours). anyway, called local dealership, chevy corporate and filed a complaint with nhtsa... unfortunately i had no choice but to take it to dealer for diagnostics and then call corporate back where they said they might be able to assist with repairs but wouldn't know until diagnostics were done... dealership informed me that they believe the problem could be solved by replacing the power steering motor if i would only pay $350 for labor (they would generously donate the motor...) i declined (for now anyway) as we will try to repair it ourselves... i cannot afford to pay for this and shouldn't have to as the car isn't that old. the warranty just ran out in september as seems to be the case for many who's blogs i have read. they also noted on the summary that the motor might not actually take care of the problem and if it didn't then they would have to replace the steering column for another $800 plus labor !! my car has not yet been repaired and is still dangerous so i don't drive it unless i just have to go somewhere and have no other option. *tr | |||

| Clutch failure, theres a mechanism that does not allow you to spin the wheels into 3rd gear on the 2007 chevy cobalt ss. this mechanism has caused my girlfriends clutch to be burned up over a one month period. the vechicles clutch no longer fully disengages and will not allow the car to move. the part(s) have not been established yet because it is currently in the shop as of 3 p.m. today. if you would like more information on this please contact me through either my email or phone number, or even reedman of langhorne. *tr | |||

| I bought my 2007 cobalt in july 2008, used only as a rental car with enterprise, with 34k miles. within 2 months, my rotors were warped and had to be replaced. milwaukee has a terrible problem w/ potholes so i've had to put 4 new rims and tires on it too and an alignment. it still shakes when i go between 45-60mph. also, the gear shift keeps getting locked in park, like a sensor is broken or something. i have to continuously press on the brake until it gives. and there must be a short somewhere because occasionally the blinkers noise (tick tick) and the left speaker go out, come back on, go out, etc. i've had the car 8 months and have this many problems with it? of course the dealership is charging an arm and leg for repairs that i can't afford but i think they should be responsible for this because there is no way these problems can be operator error. this is a manufacturing problem! i can understand the tires & rims because i've hit too many potholes but everything else? come on. anyone else complained about similar issues? *tr | |||

| Tl*the contact owns a 2007 chevrolet cobalt. while driving 50-60 mph, the vehicle failed to upshift. the gear would remain in the downshift position. when a trailer was attached to the vehicle, the gears would not upshift and the vehicle could not accelerate. the trailer nearly rear ended the vehicle. the failure occurred numerous times and was taken to the dealer twice, but they could not determine the cause of the failure. the vehicle is currently at the dealer and they believe a new transmission control module is needed. the module has been replaced twice, but the failure still persists. the contact believes that a recall should be issued. the failure mileage was 7,048 and current mileage was 34,449. updated 12/22/08 *lj. updated 12/22/08. *jb | |||

| 2007 chevy cobalt- many problems, electrical comes off and on, car rides like a bucket of bolts, at 50,000 kms front passenger wheel had 1 1/2 inch movement while parked. very dangerous. why no recalls for these issues? the fixer of the car replaced a suspension control arm bushing. all kinds of noise, all pot holes i thought the car was going to fall apart. hunk of junk car. many safety issues should be investigated. brought back to the dealer several times for sagging doors on two door model, irregular idol, rattling sounds in the front end to no avail. thank god i only leased it, they can keep it, it is a hunk of junk. i would never recommend this car to anyone. *tr | |||

| I have had a series of problems with my 2007 chevy cobalt in the last 4 months. first in november of 2009 my wheels were too bent up and needed to be replaced. then in december 2009 my clutch burned out after only 47,000 miles. everyone i ever spoke to never heard of a clutch burning out so soon. i was on the highway going 65mph when no more power was being supplied to the vehicle after pressing down on the gas. i rolled into a nearby gas station and had the car towed to the dealership and the diagnostic confirmed my suspicion. i had it replaced two weeks later when i had the money. now its february and my parking brake will not engage. the car was bought brand new in 2007 and had regular maintenance done on the car, ie brakes, oil, filters. i could have been injured and i fear driving the car thinking something else will break down. no warning signs of any of these problems were noticeable. *tr | |||
