Chevrolet Cobalt hesitation problems

Filed Aug 19, 2020 · Fuel system · 143,385 miles · OH

After filling my car up on 7/28/2020 my car started having issues with starting without hesitation. I took it to the shop to have my oil changed and quickly realized I was losing gas. I ended up losing my tank of gas and had to return to the shop to have my entire fuel line replaced. I noticed that I was leaking something while backing out of my driveway and could see the trail of gas on the pavement. When I took my car back to the shop it was severely leaking gas near the rear left wheel well.

While the car is running or while the fuel system is still under pressure, for example after having been driven there is a steady fuel leak in front of the drivers side rear tire. I have parked the car only to have lost 1/4 of a tank of gasoline to the leak. There is a very very strong odor of gasoline that permeates the car. Sometimes the car will hesitate to start, the engine continues to crank after I release the key and then it finally catches and starts .I understand this has been recalled in only certain states.

Increasingly the vehicle is not operating properly. The lighting is not consistent and the smallest addition of extra features requiring power (ex: using one or more window controls, heater and or defogger, lighting in dash at full capacity, musical performance, radio and bass, etc) will cause the power of existing devices to flutter or surge for example the headlights will dim out when turning the windows down or the vehicle will begin to vibrate and shake even more almost as though it is overpowering and wanting to shut down or quit. Also the rpms will feel like they are hiccuping or bouncing down and up more than usual and at random times and speeds at times seems like its going to red line even if you take your foot off the gas. This is also a bit of the same type of issue but it is the opposite when you push the gas it hesitates or something like that glitches or jolts and gains power very slowly and has a hard time accelerating and gaining speed (seems gutless?) . And at stop lights and whenever parked its rumbles and shakes all together let alone if you are using the radio or heat etc it's loud enough to have to get the people in vehicle to almost yell when talking over it or if you are in a drive through the person can't hear you and either have to stut off the engine or speak to them in person at the next window. Also when you are slowing down to stop it almost seems the engine will be faster than the body or something like that (I know sounds crazy but I don't know how to explain it any other way) . I've come to the conclusion that it will be fuel and or electricity related or both. Its also randomly showing a few different codes and then suddenly they go away all to do with fuel pressure or syster or evap type thing. Without clearing them they resolve themselves without any work or anything witch also seems very oddto me. Thankyou in advance for reading.

Tl* the contact owns a 2005 chevrolet cobalt. While driving at any speed, the power steering seized. The contact had to use excessive strength to turn the vehicle. The vehicle also lost fuel. The failures occurred without warning. The vehicle also hesitated and jerked violently, and "faulty power steering" and "loss of fuel" appeared on the instrument panel. In addition, the service engine indicator illuminated and the transmission made an abnormal shifting noise. The contact called anderson chevrolet (31201 auto center dr, lake elsinore, ca 92530, (951) 226-0822) and was informed that the transmission recall was serviced in 2009; therefore, the contact would have to pay for the repairs. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 120,000.

2006 cobalt has been showing the power steering display on the dash light and when it does the engine starts hesitating and rough idle I read a few minutes ago about a recall of maybe the same situation a few years back but didn't know that at the time and didn't think that my cobalt would have that problem

When driving at a constant rate, with constant accelerator pressure, between approximately 25 to 50 MPH, the rpms jump/fluctuate causing the car to lurch and hesitate. This can be a safety hazard, particularly in icy conditions. The only way to avoid the hesitation is to actively accelerate or decelerate. There are numerous owners that have posted an identical issue on message boards and have stated that their vehicles had similar issues that were remedied by similar repair processes and that chevrolet has altered the process used to make replacement parts as the initial parts were defective. In addition to being a safety hazard, it is also an excessive and costly burden on vehicle owners. My vehicle has only 40,000 miles on it and has been doing this since under 35,000 miles. It cannot be documented without a video. The rpms jumping is a constant and unrelenting issue when driving at a constant rate of speed between approximately 25-50 MPH.

Strong smell of gasoline in the vehicle and around it. Hesitation in starting vehicle. Took to have looked at and was told our fuel pump has a bad leak. Did research on line to find out other VIN 2007 chev. Colbalts also having this problem and most were covered by a recall. However, our is not! Our daughter drives this car 2 hrs a day and it is such a fire hazard. How is this not included in the recall. This is a huge safety issue I'm sure you agree. The risk of fire from the gas leak and the large amount of chev cobalts that have had this issue makes no sense you wouldn't cover the repairs. Please tell us the way to get this expensive repair taken care of. We insist you cover the defect! Thank you in advance and prayers no one is seriously injured with this defect being such a problem for gm.
