I had recalls fixed in 2015. And then suddenly power steering turns on and off. Never before they touched it was there an issue. It happens here and there and stops. This year is happening every day and won't go away. My power steering turns off in middle of driving. Dash board lights go off and car starts cranking. Goes super slow. I'm scared ita going to explode. I can't drive on freeway. And now besides the lock on screen coming on my engine light stays on now. Not sure what to do with it. Car shops can't help. When I 1st had the issue I called the dealer because they fixed the recall and they said nothing could be done because they had already fixed the recall

Instrument cluster malfunctioning, speedometer and warning indicators flashing, going out, resuming normal operation, then repeating the failure symptoms repeatedly. During failure symptoms the transmission and engine bog down, stall and the power steering assist fails (with engine still running). Random electrical issues such as the check engine light, car alarm sensor, etc flash on and off then start working again totally normally. Can not get the failure to occur at the dealership or mechanics. Fails several times a week. Fails when driving on street, highway at low speeds, medium speeds or high speeds.

My 2008 Chevy Cobalt began secreting a very strong fuel odor; it didn't matter if it was parked, or driving, the odor has been prominent 24/7. I checked for leaks and found nothing. I recently moved, so I have yet to find a new, trustworthy mechanic, so I've been driving my husbands car due to the fact that I do not feel safe driving the Chevy at this point. I had however, been regularly starting the engine once a week, while trying to locate a mechanic, however now. My Chevy is completely dead; it wont turn on, nor will the lock system even function VIN number: [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).'

Coolant is not reading, air conditioner don't work and check engine light comes on. It will stay like this for a day or so then by the time I get it into the shop it starts to read again and the check engine light goes out air conditioner will work again and there are no codes to read. Repair shop can't find anything wrong. They said possible thermostat issue or sensor issue but without codes or check engine light on they have no idea. It keeps doing it but it seems to correct it self before I can get it back to the garage usually over a weekend when they are closed or very busy. I have had this issue for a couple months now, it has not appeared to cause any over heating or made any other sounds that I am aware of.

Start of the problem the gauges will go eratic, my car chimes a few dings then theft light comes on. I don't have a theft system. Ls model. Also effects the transmission(automatic) cause it will shift hard and jerk the car. The ac also shuts off during this issue, it will blow air but it won't be cold. Seems like the issue always comes back when it's extremely hot outside. This is an on going issue for about 5 years and it comes and goes. Every mechanic I went to their car reader can't read my car. Also it has happened while I was driving and again when I'm parked and just started the car. And I have had all the recalls fixed that were reported.

I started my car in my driveway, it started and then stalled immediately and would not start at all. I diagnosed it along with my friend who is a certified mechanic. The cam chain guides broke at less than 79000 miles, causing slack in the cam chain which caused it to jump teeth on the intake cam, throwing it out of synchronization. This caused the intake valves to be open when the piston reached the top of its travel, which bent the valves. This is a very common issue on the 2.2 engines, but very unusual for such a low mileage vehicle. The engine has a 100,000 mile warranty but only for 5 years. I only drive on average 10,000 miles a year. The engine is well below 100,000 miles and GM will not admit that they have a design flaw on these engines and will not make this repair for me under warranty.

My fuel pump was leaking, so we had the fuel pump replaced and now the air conditioning/heater/defrost systems no longer work. We've had to replace the steering column, the fuel injection, and a leaking front windshield twice.also the fuel switch. Now the car somewhat stalls when trying to start.

Was driving to san diego, first stop of several on a vacation. Stopped at a stop light. Went to proceed as light turned green, heard a scraping and grinding sound; there was little to no power for the car. It couldn't go above 30 mph, and made a "loud noise" (as stated on paperwork from dealership). Got to city (by the bay) Chevrolet. I ended up spending $1334.21 for a new catalytic converter and two gaskets. I was also out $111.26 for a rental as I was going to disneyland and knott's berry farm after a stop to san diego. I had to have the rental from Thursday to Saturday or I would have missed time at disneyland. I picked the day for knott's berry farm. According to Chevrolet, the 2005-2007 Cobalts in Nevada (where I bought the car and live) are affected by a catalytic converter issue; however after contacting Chevrolet and advising them of my issue -- they tell me (despite the identical issue) -- my model is not affected. I am looking for $1445.47 in compensation for actual losses. I would like compensatory damages since Chevrolet is refusing to do the right thing and investigate or reimburse me and it affected my vacation. Also, I want the recall extended to the 2008 models.

While driving on the route 20 at about 50mph it started to rain and all of a sudden my car "reduced engine power" light went on. My car started slowing down and I had to turn to the closest street so that I wasn't hit by the car behind me. This has happened before, last year while on the highway driving to cleveland, my car began rapidly slowing down and I couldn't pick up speed while pressing the gas. I took the nearest exit and had to wait two hours before the engine light would turn off. Also, while the check engine light is on, it also says "traction off" and my car shakes. Both times it was raining, and I was driving at 50mpr speeds.

I have read a lot about this on line and find numerous complaints related to this same issue in this same model.... please help... I feel this is a safety matter.... could stop in traffic or on expressway which I travel each day. Many thanks!

Clutch is losing pressure, can not shift gears to drive the 2008 Chevy Cobalt ls (manual). Must pump clutch over 200 times to get pressure back. The clutch pressure goes out while driving on street and the highways, making it no way to downshift/ slow down. Could cause injury to all passengers.
