2 Engine And Engine Cooling problem

Failure Date: 07/24/2024

The car idles very low when stopped and sputters/putters like it's going to die. It has now actually died on me twice while driving, luckily when you put it in park and turn the car off and back on it starts right back up but you can see how this is a severe safety hazard. The first time it died I was stopped in the turning lane waiting on trafiic to go by so I could turn left (this is the busiest street in town) I go to start turning left the car just shuts off mid turn crossing the other lane of the street, luckily I didn't get hit by oncomig traffic and was able to coast onto the side street that I was turning on and pull over and turn the car off and back on and drive it home. I took it to the mechanic and he can't figure out what's wrong with it so he gives it a tune up and now the check engine light won't turn off. . . Fast forward to today it dies again at a stop sign with my 12 year old son in the car. It is especially bad if you have the ac on it seems like it effects the elctrical like the car is going to shut off when I am stopped and the ac is running, so I turned off the ac and it was still sputtering when I would stop but didn't die again. .

4 Engine And Engine Cooling problem

Failure Date: 01/01/2022

The problem that sent it to a different mechanic than the chevy dealer where it came from after a month and 900. 00 bill for 550. 00 ecm and diagnostic test they did without my permission, there labor for the test and ecm was a total of 900. 00. Plus claimed it was throwing a code for a peddle that it needed. We just put a brand new peddle and brand new throttle body on it, it was idled to high, so reason for them getting it was to get the old ecm and new throttle sinked up to reduce the idle , at the time of it leaving me it started and ran just idle to high. Throwing no codes. They got it, claim it wouldn't start so did a diagnostic claimed it needed a new peddle. I said I'm coming to get it, they didn't tell me at any time I couldn't drive it home. I left there lot and pulled about 150 feet off the side of road because it wouldn't shift. Called them , botched did no good. Called same tow truck to tow it home. Got here it was idled normal but was throwing a different codes, I turned the car off it wouldn't stop running for about 3 to 4 minutes, then it died. I had it towed to different mechanic for the ignition to be replaced. He said it was throwing a couple codes still ignition not fixed yet, and it ran for about 15 minutes after shutting off the key. At no time here or at the new place did it throw a code for a defective peddle. So now it's be gone for 2 months , new ecm , new throttle body ,new peddle, idle is fixed and car runs but won't shift. Codes its throwing is now are just needing coil on #4 checked and throttle position sensor adjusted. So far that's it. 2 months later. Still not ready for pick up.

7 Engine And Engine Cooling problem

Failure Date: 08/05/2020

Before I get into all of it there has never been an accident not yet at least. I do everything I can to try an stop that from happening, (but accidents do happen) only because I know my car could kill on me so I’m extra careful. 1) after I get gas I’m my car the car won’t start right away. I have to restart it a couple times an step in the gas an rev up wasting the gas I just put in to get it to start. 2) when I stop an start to pull out of somewhere on to a main road the car will just die on me so I’m stuck pulling out in traffic trying to get my car to start again. It’s when I come to a stop an pull out it just kills on me. So I have to make sure no one else is coming an I have enough time to be able to restart it otherwise I’m worried when I pull out of anywhere or stop an go that another car will smack into me because my car just died on me in the middle of the road/ pulling out an crossing lanes. Super scary! 3) let get into the next issue so anytime I run my ac my car starts to do this jumping thing like it wants to kill on me not to mention it has killed on me with the ac on (I live in louisiana an it’s too hot not to have ac plus I have 3 kids) what’s sad is the ac works fine but if you want the car to maybe not die then turn it off an you have a better chance of it not killing off on you but not always a guarantee. So ill run it for second to try an cool down so I’m not drenched in sweat but I have no other choice to turn it off so the car doesn’t just die on me. This refers back to the 2nd problem I make sure it’s off anytime I pull out of anywhere thinking that would help it from killing on me while trying to get out of anywhere but it doesn’t but I can tell you if the ac is on when I pull out when I start to go it dies right as I’m in the middle of the road every time never fails. Mechanics have replaced parts trying to fix the issue, but it still happens I can’t keep buying/fixing things for nada, ongoing problems since buying.

Sometimes the car won't even start, it won't kick over, on the digital display of my dash I get dash marks cause of a computer error cause of a another faulty ignition switch. The cars gauges as I try to drive will not work, the icons on the dash will keep rotating from other icons, this car is dangerous in my own opinion. When I drive the gauges won't work and it's so dangerous, I can't see the speed or my rpms, I can't see how much gas I have, my radio is no good, the leather they used for the seats was garbage, the paint was done by an amateur, the paint is coming off the car, rust is developing, my doors will open and close themselves, I never had this problem before doing the recall. The ignition switch turns off my airbags,my radio does not work, my wheels hubs have broke cause they used cheap wheel hubs on a sports car, the ignition coil packs are garbage. The car is defective, I spent close to $22,000 to $24,000,in 2006 for my 2006 Chevrolet Cobalt 2. 4 ss which has less than 71,000 miles. They pushed a cheap crappy parts car with cheap paint and no rust prevention,also the wiring of electronics in the car was complete [xxx], the wiring harnesses on all the wires is crumbling,the wiring to the battery in the rear trunk of the car is a fail,Chevrolet pushed a car out that was no ready for market,they pushed a car out that was defective and dangerous.

32 Engine And Engine Cooling problem

Failure Date: 04/02/2014

I had become aware of the recall, just the week prior and was planning on making arrangements to have the car fixed, once the parts (3-4 weeks out from what I was explained) arrived. I was also explained via the dealer and what I read on line that the car should be ok to drive so long as there was nothing on the key. So I requested my daughter to only use the key with absolutely nothing on it, when using my car. At approximately 2pm on a clear sunny day, my daughter was exiting the freeway. As she was slowing down, the car suddenly shut off on her. Before she had time to react she hit another vehicle. She was fortunately not injured, mainly because she was already slowing down and had it been a few minutes earlier, things may have been drastically different. I have had this car for 7 years and I drove it quite a bit and let my daughter do so as well. I am angry that gm has allowed my daughter and I to be at risk for such a long period of time and even as I am writing this (2 weeks later) the only answers I have really been given from gm are answers I have had to call and press them on, which for the most part is almost no information at all. I am sure they are being inundated with complaints and having to deal with the media, congress, NHTSA, but I cannot feel any empathy or sympathy for that matter, when they have had years to deal with this and simply swept this under the rug. Harsh and swift action must be taken to punish them and set an example to all others. Enough with the bail outs. Time to start being accountable.
