CarComplaints.com Notes: The 2006 Cobalt continued to carry the torch first lit by the 2005 model year. To be clear, that torch is burning bright with widespread power steering issues, electrical curiosities and a dangerous ignition switch defect which led to a massive recall by GM. This isn’t a great torch to carry.

The 2006 added it’s own special flare with gas leaks due to cracks in the “return portion of the modular reservoir assembly.” A recall of 2006 Cobalts was issued to fix the problem, but only to vehicles sold in or current registered in Arizona and Nevada, leaving other owners to pay for repairs themselves.

Between this car stalling while driving, giving owners fits with power steering failure and having it be a potential tinderbox because of gas leaks, we felt we had no other option than to award it our “Avoid Like the Plague” badge.

I have a gas leak under the car wherevtha gas tank is. I have had this leak for awhile. Wanted to know when the recall will hit Georgia so I can have it fixed. It smells like gas at all times. Almost to the point of making you sick. They have a recall for this in other states. Want to know when it will hit Georgia.

Takata recall: I recently purchased a vehicle from someone (private owner) and as the tags will soon expire so I decide to get what needs maintenance done to turn that check engine light off. I got a free estimate from O' reilly's and told me to go to Chevy and get the maintenance done to my safety recalls. Next morning I drive over to Chevy's dealership where I was denied any recall being done by an employee named sean popplewell. I told him to print me out a paper of what had been done, needing to be done and also took it up with the manager. The service manager confirms I cannot be denied for a maintenance but sees that the only maintenance open online is a service update and that there is nothing they can do salvaged or not. As I recently purchased the vehicle I am being denied my right to a safety recall, not only being denied while driving my 1 and a half year old son, in a vehicle who's check engine light is on due to the safety recalls that I am being denied to. I am within my right to 10 years after the recall is distributed to get the recall done within that time, they are not allowing me too. The car is 100% driveable but I need to get this taken care of so I am not denied in my smog test. I was also not the original owner and the law states that I am not held accountable for a previous owners lack of responsibility, I was not aware, I've never had received proper notification I should not be denied service. It's sad to know they have denied me these rights in front of myself and my 1 and a half year old who is in the car 24.7.

The vehicle can mess up from either driving down the highway or trying to accelerate the vehicle on city street or highway that the engine stalls and says "engine power reduced" the check engine light along with the T/C light comes on. It happens multiple times in just 30 minutes of driving, more for longer trips. It will even do it in 10 minutes of driving. You have to pull over and turn vehicle off for a few minutes and then it drives fine for maybe a mile down the road before it does it again, or, you can continue driving it with the pedal all the way to the floor board trying to get speed which if you do the car shifts gear very badly and rides rough but when you're trying to get to work on time you do what you have too. I have taken the vehicle to a mechanic 3 times over this. Throttle body was changed (twice), they replaced the computer and cleaned the wires. One mechanic was the Chevrolet dealership and they told me they needed it there when it happened to better diagnose the situation. I do not have the ability to let them just keep my vehicle. I have had this vehicle for a little over a year. I bought it used. I have a loan on the vehicle and I am scared to drive this any further than I have to because I know the vehicle will mess up. I have two children that I have to put in this vehicle to take places. This vehicle is extremely unsafe!!!!!!!!!!!!!!!!! I want help with this situation!! this first happened in November of 2016. I do not know the day specifically. I do remember it did not fall under the dealerships warranty that I got it from.

Some time ago I received a recall notice for the fuel lines. I contacted dealership and they refused to repair. Currently I have an active fuel leak around fuel tank when driving. Somebody told me about this website, so I am writing here to see if somebody can enforce recall for my car. I don't remember now when I was rejected, so I will put /1/1/2016 for the date. Thanks.

My 2006 Chevy Cobalt ss smells of gas both inside and outside of the car. I researched this issue with my make/model/year of car and found that other states (not mine), had a recall involving the fuel pump on this car. I don't understand why other states didn't recall this issue when many other states have complaints about this issue? I live in Michigan and many others have posted the same problem with their car yet none of us are in the 2 states with the recall. All states should be included as this can cause a fire! I shouldn't have to pay for this to be fixed when it is obvioulsy a serious problem!

There was a regional recall done on the fuel pump module on many different GM vehicles. Due to a crack in the plastic around the modular caused by extreme heat exposure. When the issue occurs, it leaks gas and fumes, also there is a very prominent gas smell surrounding the entire vehicle hours after being parked. I live in Kentucky, my VIN is between the VIN breakpoints on the recall but due to my region, I'm not included in the recall. GM to save money has made a special policy concerning this issue to fix the problem and pay fully but because it is not a "safety concern" which was said to me by Chevrolet customer representative paul, it wasn't a dire issue. This is a safety concern directly stated by NHTSA, and the part in general should be recalled completely not just regionally. I am now, due to it being my only transportation, until I can afford a rental, driving a vehicle that is leaking gas and fumes due to a faulty factory part put on my vehicle by GM. This issue should be addressed. Consumers are in danger and due to not being in a certain "region" we are risky our safety and the safety of others because we can not get a fair recall done.

A few days ago, we were in the garage and a strong odor of gasoline was coming from our car, a 2006 Chevy Cobalt. We checked online to get this problem fixed and noticed that only Cobalts manufactured in Arizona and Nevada were covered. Really GM. Since we live in Ohio, our safety is not high on the list as those who live in Arizona and Nevada. I really hope that NHTSA can enforce a recall so this issue can be fixed. There are many complaints surrounding this issue on the internet.

Smelled gas outside and inside car while driving and parked. Looked under car and gas was leaking from fuel line in front of driver rear tire. Fuel line in close quarters with exhaust and was spraying onto exhaust pipe. Contacted dealer to check on price of repair or recall and dealer stated they have had many Cobalts similar year with leaking fuel line in same location. Stated GM used an absorbent heat wrap on that section of fuel line and that is corroding the line. Cost for replacing lines was over $800. I am deciding on repair route due to excessive cost of repair. This is an extremely dangerous failure in GM's end and needs the fuel line recalled. Appears both lines are leaking right by each other. This is a fire/explosion hazard and is very common. GM recalled the fuel pumps for possible leaks but not these failing lines? my garage kept low mileage (97000) car should not need it's fuel lines replaced already, especially at $800 plus.

The fuel lines in my 2006 Chevy Cobalt began leaking yesterday. A fuel smell was noticed in the cabin of the car. I also noticed some dripping fuel in the rear of the car. I took it to my local Chevy dealer and was told it was not covered under the previous recall because it was not the plastic line that went into the fuel pump. While off the car just dripped fuel about 1 drop every 10 seconds. While running and stationary it was a steady stream of fuel pouring out.

I am copy/pasting the recall notice. This is happening in a vehicle in Mississippi. General Motors is recalling certain 2006'2007 Chevrolet Cobalt, Saturn ion, and Pontiac G5 vehicles registered in Arizona, Nevada, California, Florida, and Texas because of a crack that could possibly develop on the plastic supply or return port of the fuel modular reservoir assembly. This crack could cause a fuel leak that could be observed dripping onto the ground in some cases, causing a possible vehicle performance issue and a fire hazard. Dealers will replace the fuel pump module free of charge.
