Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. Notes: The Cobalt was introduced to replace two of Chevy’s smaller cars, the Cavalier and Prizm. But the compact’s fresh start that Chevy was hoping for was riddled with issues, most notably widespread power steering failure.

The power steering failed so often that GM was forced to issue a recall in March, 2010. Great, but what about other problems like the key getting stuck in the ignition or all the other electrical demons this car possesses?

And, oh yes — then there’s the terribly dangerous issue where the Cobalt randomly shuts off while driving. As it turns out, that problem is related to GM’s massive 2014 recall for a dangerous ignition switch defect. A recall that eventually ballooned to 2.6 million vehicles in one of the automotive industry’s biggest scandals.

Our vehicle is leaking gasoline and is exhibiting the same symptoms as those addressed in this recall NHTSA campaign #09V419000 but Chevrolet says that it doesn't cover the 2005 model and we believe it should since it is the same problem.

My car is leaking fuel at the gas tank. GM recalled the 2006 Cobalts but mine is a 2005. My car could explode and gas in our public water system is a huge concern. This car is a lemon!! I have extreme anxiety of dying in this car. I need someone to get GM to recall my car asap before I die!! I cant afford to fix it.

My car turns off in the middle of driving. Three times I have been on 45 mph roads, and have 2 small kids. This isn't the only major issue my car. But first the digital display reads engine disabled or engine losing power then engine disabled and loses all function. There was a recall over a year ago for this model shutting off while driving supposedly due to weight on the key ring. After the dealer fixed it the issue stopped until 3 mnths ago. I can only go a block before the engine disables now, it progressively happened sooner and sooner. A friend who is old buddies with a diagnostics specialist introduced me and he was able to tell me exactly what was going on to fine details. I called the dealership to see about any recalls and relayed the info he'd given me and they down played it like they guy didn't know what he was talking about. The dealer thinks its a throttle or engine problem. The guy I know said the computer chip in the key likely got messed up possibly from having my cell phone next to it a lot, that the part in the ignition that reads the signal from the key is getting mixed info and signals the engine to shut down. He also said that once it happens, a loop is created to where every time I turn they key it starts the cycle over where everything is okay in the beginning but the info gets misread over N over which is why he said I should get a new key- and (I think this is what he said) to replace to whole ignition column so all parts involved would be new. He also gets his parts wholesale and is not trying to rip me off. Next problem car burns oil! the last two times I had oil checked, nothing on the dipstick, I get it done every 3000miles. Walmart made me sign a paper stating there was no oil on dipstick. Gas line corroded, smell of gas throughout car, has whole piece replaced. These are serious why is Chevrolet doing nothing bad business

The vehicle will periodically jerk/hiccup at random while driving. On January 8, 2015 while traveling on the expressway, the vehicle began to randomly sputter/jerk/hiccup. The vehicle did not loose power, or was there any indication from dash board icons of any malfunction. There was not any visible warnings signs to alert a faulty system. This has occurred previously, while traveling throughout the city at speeds of 25-45 mph. During the most recent incident, traveling speeds varied from 50-70 mph on the expressway. This particular instance I was driving a 60 mile trip and this jerking occurred 7-10 times. The first time this occurred was probably 1.5 years ago. The vehicle was taken to a mechanic after the first instance, without anything being detected or a diagnosis. The issue is progressively worsening. It is beginning to happen more frequently. Last week, of the 4 days of travel on the expressway, the jerking occurred 3 of those days. Initially, I felt, this was associated to the cold and weather/temperature, but this has also occurred in warmer months. This is a definite safety issue, as it relates to myself, and others traveling in my vicinity.

Fuel system does not keep reliable fuel readings, particularly within the last 1/8 of the tank. It will often register as empty after having shut off the car with 1/8 of a tank only moments before.

The fuel pump is defective and leaking gas this is a recall on the 2006 models and up but not on a 2005 model. There are endless complaints online about the 2005 models leaking gas but there are no recalls on it yet.
