Electrical System Problems of Chevrolet Cobalt - part 1

The fuel tank has an evap leak that somehow breaks on top the tank so it leaks the gas vapors and could potentially start a fire but the part that breaks is a non serviceable part so it can’t be fixed without purchasing a whole new gas tank that isn’t cheap. My other concern is the infamous grounding issue with the wires on the ground g105 I believe right next to oil filter that grounds the transmission and engine control modules well it shorts at times when driving and suddenly your car dies while driving how scary it could cause a wreak and kill somebody it’s a very scary issue that constantly comes back even after trying to re ground it needs to be recalled and fixed it’s going to kill somebody and it’s a well known issue for this make and model that should have already gotten attention to be resolved.

Unknown. My traction and abs light keeps coming on. My steering is off some. My turning right or left is making ruff popping sounds in the steering. My abs and traction lite keeps coming on.

I started up my car and it was very hard to turn the wheel easier when I gained speed. The warning said "power steering".

My speedometer jumps and shows a message of power steering. It makes my fuel line jump as well. I've recently gotten my starter fixed because my car wouldn't start. My tire warning stays on and my tires are new and set at the right psi. My abs comes and goes all the time and nothing needs to be fixed. My car jerks really hard when all of this is going on.

While driving the car, it will suddenly stall w the engine running but won’t react the use of the brakes, steering or gear shifter. It’ll suddenly jerk and the following lights will appear on dash :abs, power steering, no brake fluid warning, low fuel warning and check engine. All of the areas have been check and have all their fluids so this doesn’t make sense. We bought this car for our 16 year old daughter and the first time she drive it, a truck almost wrecked into her.

Ignition switch had a previous recall, but now the ignition switch won’t turn the car on on the first 5-10 switches with any keys, or spare keys. Steering wheel shakes/wobbles when exceeding over 50mph.

Abs light lit, traction light lit, power steering light lit, car jerking, not shifting. Stalling.

I was drivein on high way in my car got hard to trun so I stoped and let my uncle drive cause he is more stronger then from that point it got harder to trun it amost locked up on me who know what would have happen but I was almost to my house so we were ablue to get it here then I called my car lot and I hade to drive it there it was so impossible to do but with the help of my uncle he got it there and im in school and stuck with out a car intell its fixed and I have to pay laber wait on part to come in thay say etc its just alot and thank god I was not alone.

I was driving down the road and I used my blinker then my car shut off while driving, its turned back on in seconds then when I came to a complete stop the car shut off while on drive and it lost communication to the tcm and it was displaying messages such as “low fuel” and the rpms was at zero.

Power steering is locking up while driving. Windows won’t go down.

Wiring harness is located too close to the human under the driver's seat. Exposes the driver to electrical frequencies that could be avoided if the wire harness was a further distance away from the human. Also, the the fuel line rusted through after 9 years about 9 inches away from the rear axle where the metal tape ends around the fuel line. The metal tape seems to allow more moisture to become trapped around the fuel line; which promotes rust and a leak where the metal tap ends. After the metal tape, the fuel line is in good condition on this specific vehicle. The fuel leak is about 0. 5 inches wide and a lot of gasoline drips / leaks after the car is started. The rust particles are located after the fuel filter; which may promote the rust particles to reach the engine via the rusted fuel line. The car has trouble starting (a delay) and needs to have the key turned twice due to the leak. The leak is very close to the muffler, so it seems like it would be at risk of catching on fire if the muffler was hot enough or if it were traveling on a long trip or going up or down a steep hill. The vehicle has been inspected by police. There were no warning lamps or lights.

I own a 5-speed manual transmission which should roll freely while in neutral. After starting engine while on a slight incline in a parking lot, the vehicle would not roll in neutral, as if all brakes were being applied. I thought that by driving the vehicle on the road the brakes would free up, but they did not. I shut the engine off and on a few times but that did not make a difference. I could only move forward at 5-10 mph in first gear to get the vehicle home, which fortunately was just 5 blocks away. Something smelled terrible like burning wires or brake pads. Even after letting the vehicle sit in my driveway for a few hours it would not free up the brakes which were being applied. Then I read a tip on an internet users forum: remove a fuse labeled "abs2" and voila! it freed up the brakes! I can drive the vehicle normally but obviously without abs capability. Now my 19 yr old grandson, who turned the vehicle over to me because of this issue, states this happened to him on two different occasions *while driving on the road!* imagine having your brakes applied while at full speed: this is a serious safety issue which could result in injury or death.

My power steering alert came up and immediately I start having trouble driving as the steering wheel got tight. Almost had a accident and there is other problems with my 2006 chevy Cobalt lt that have been on recall and I cannot get any help at local dealership.

The contact owns a 2007 Chevrolet Cobalt. The contact’s mother stated that while driving at various speeds, the vehicle would stall without warning. The contact stated no warning lights was illuminated. The vehicle was towed to a local dealer where it was diagnosed with needing the ignition switch replaced. The vehicle was not repaired. Upon investigation, the contact associated the failure with NHTSA campaign number: 14v047000 (air bags, electrical system) however, the VIN was not included. The manufacturer was informed of the failure but offered no assistance. The failure mileage was approximately 107,000.

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.

The receptacle that holds the brake light gets so hot that it melts and has melted the plastic around it as well. The bulb won’t stay lit because of this therefore the brake and turn signal lights constantly burn out and it could cause an accident due to lack of signaling and could also very easily start a fire. It started about 2-3 years after we bought the car new with just having to just replace the bulbs much too often, yearly, then a couple of times a year, and now the bulbs are not even lasting a month and the components are actually melting.

My headlight an blinker quit working new bulbs an all new wiring it it still will not work my trunk button also just stopped working an the fuse is not blown. I even replaced it just to make sure still nothing. Door panel clips won’t stay in bought new ones same thing so now my handle is coming apart an my door doesn’t want to shut bc it thinks I’m still holding the handle. . Fuel everytime I get gas I have to crank my car a few times and press on the gas before I can get it to go otherwise it just dies on me I’ve had it looked at they said it was something about how my car does not know when to stop releasing air I think. My blinkers don’t turn off unless I do it manually. The seals on my door is no good anytime it rains it’s coming inside of my car an since the door panel won’t stay on it’s coming straight into my car.

While driving power steering message showed on dash, lost transmission control, and speedometer stopped working.

The tcm in my 5 Cobalt is not working properly I've tested and replaced everything els and had the tcm reprogrammed still getting problems aiming back to the tcm it wasn't looked at by a business.

With no recent changes to the car, it won't start, theft lock symbol is on. Tried the spare key. Tried theft lock relearn 10 minute and 30 minute procedure. Disconnected and re-connected negative battery terminal. None of the steps worked. This issue has the potential to keep families stranded.

Instrument cluster lights do not work and electric power steering dose not work.

The air bag never deployed I bought car in 2018 from original owner with car only having 33,000 miles on it and still under warranty til car had 100,000 miles and I hit a deer head on 2 months after getting car which bought in may of 2018 hit the deer in July 2018 . The deer was hit with the front passenger side it broke my headlight n messed my hood up and smashed in the grill little and my air bags never deployed I hit deer at 50 mph , after that had happened I took it in to chevy dealership and had them look at car cause I told them I hit that deer and air bag never deployed and that my air bag light came on once in awhile and said service air bag . The dealership said they do that sometimes and did something to make light go off that was it my air vag light still comes on and says service air bag . Also ignition switch and fuel smell foul coming from car a lot and is as I speak . My reduce engine power light comes on a lot and have no power to gas pedal n car won’t stay running . I have try to get two recalls fixed back in 2-21 I was having problems with my car back then too special reach called me in Jan of 2021 and told me that there were two recalls on my car ignition switch and fuel module so I informed dealership when I took my car in that next month in Feb 21 told them I was informed on 2 active recalls on my car . When they were done with my car later that day I asked them if they fixed the recalls they said no cause it was map sensor so I then made an appt to get recalls fixed when I got there for the recalls to be fixed one of the technicians told me it shows that they were done . I called chevy and complained about the issue I just had and never had recalls fixed but they must of put it in computer they fixed them so I’ve been really upset that I been trying to get past recalls fixed that are on my car and I get run around and told there isn’t any I know about a past recall on shift selnoid low circuit too that was a past recal.

Will not start- ignition bad - relay bad.

Power steering warning came on while driving on the highway an the speedometer stop working now the car won't start I have checked fuses an relays unhooked battery to reset computer nothing works.

The accelerator pedal constantly fails to activate immediately after turning it on. It used to happen on cold or rainy days. It now fails to activate all the time. Took it to an independent service center and they said it could be the wiring due to water getting in the car. My car did have a leak and it was fixed but many months after these issues started occurring. I get a check engine light with a service traction control, service esc, and code p2138 is shown.

Power steering message came on while the car at high speed driving and car shut off/engine shut off completely, thanks god was on a rural road and there was not much traffic. Try to start car the security lock came on. Security lock comes on the car very often leaving me stranded. The car has 54000 miles.

I went to turn the car on and it wouldn't start. As I tried to take the key out of the ignition it locked itself in and have not been able to remove it. I was going to attempt the car jump but I couldn't put the car in neutral to move it to a position to get a jump because the gear shift is also locked. It is impossible to move this car as is.

1. Gas smell - fuel leaks after leak fix still smell gas (even after setting for a couple of days. 2-door lock issues-even after fixed by gm-now won't lock at all 3. Air bags- gm stated that they could not get parts in 4. Electronic issues -start auto now show-power steering, had checked by gm wont ecm won't cummunicate with tcm. I have had all of this checked by anthony Chevrolet and nothing has been done! state they cannot get parts and or not worth fixing.

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.

Car shuts off and loses power while driving and the key keeps getting stuck in the ignition and the doors keep locking and unlocking constantly until it loses power again after changing the battery.
