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.

CarComplaints.com 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.

Cobalt

  • 51,000 miles
This issue seems to be a common problem with the 2005 Cobalt. Please research any car complaint websites about this certain vehicle. Even though all the recalls have been taken care of, while in motion, at any time and any speed, the dash lights starts flashing and you get the message power steering on message center, tc light comes on, light that shows padlock symbol comes on, RPM needle jumps up and down, steering wheel locks up, motor surges and shakes, and you hear all types of clicking sounds below gear shifter. This is a very dangerous thing and Chevrolet/GM just cannot seem to fix this issue or even find anything wrong. The 2005 Cobalt needs to be recalled and any other year of Cobalt having this issue. I will give you below the last date this has happened, but this has went on since we got the car in 2008. My daughter is in school in Kansas City, and this issue has happened quite frequently lately. The only remedy is to pull to side of road, shut off vehicle and restart and hope it does not act up again. I just wonder how may deaths have happened already because of this faulty GM product and no one knew it was because of what the Cobalt did, locked up on its driver.

I was driving the car in the city street when the engine light came on. I continue to drive the car when I start hearing click sound than I hear bell sound come from the car. The car wouldn't go any faster than 40 mile hr & the gauges were jumping all over the place. I continue to drive the car then the words "power steering" came on where my mileage would show. All of the recalls have been repaired and something still wrong with this car. I asked GM to take look at the car without charging(money) to see if it is relative to the recall. The dealership said they couldn't tell if they would charged me money or not.

Cobalt 4-cyl

  • 139,975 miles
While driving on the street my car signaled reduced power, then engine disabled. Car slowed down to about 10 miles an hour, could not accelerate. Had to pull the car over, and turn the car off. Waited about five minutes and restarted my car. This happens about three times daily, and I was told by Chevrolet and GM that it's a common issue with Chevrolet Cobalts between the years 2005 and 2009 but this is not on recall. Today my car stalled five times and my bumper was hit by another car. I've been calling Chevrolet for the past two weeks and trying to see what can be done about my car as it is the only issue.

Cobalt 4-cyl

  • 171,654 miles
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.

Cobalt 4-cyl

  • 80 miles
I purchased a Chevy Cobalt brand new in 2005. From the moment it left dealership I have had one recall issue after another. The main issue is stalling while driving caused by the ignition switch. This had been fixed at schumacer Chevrolet several times. My vehicle continues to stall and I am terrified of causing an accident due to this recall which GM refuses to fix. I feel I was sold a lemon and all I get from GM and the local dealers is nothing. My vehicle is worse with the stalling. I don't know where to turn to. Please help. I don't want monetary compensation from GM if I or any passenger in my vehicle dies in an accident due to a malfunction due to GM.
