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.

2009 Chevrolet Aveo Owner Comments

problem #4

  • 15,000 miles


I have a 2009 Aveo 4 door with hatchback I bought brand new in April 2010. We have had tons of issues with it. It had a battery leak due to a bad weld job that cracked the battery and acid went throught the engine area (and all over our new home's garage and drive) all the front end has been replaced from the axle, cv boots, lower control arms (just replaced yesterday). This has been an ongoing issue with mulitple trips to the dealer and stays in the shop. Now--new issue---hubby was driving home in stop and go traffic and the car just stopped moving. It was revving up but the car was out of gear so he and his car pool buddy pushed it off the road, shut it off, and then tried to restart it but it did not want to start back up. They walked around it to see if they could see if anything was leaking and looked under the hood and seen nothing out of the ordinary. They got back in and it finally started up after 10 minutes or so and all was fine. Took it to the dealer and when I checked in the guy popped the hood and pulled out the transmission fluid dip stick. He said "no freaking way" over and over again as he put drops of the fluid on his paper and smelled it. He said that the fluid was way dark and smelled burnt and there is no way a car with less the 15,000 miles on it should have that kind of transmission fluid. Well they kept the car overnight called me today to tell me to come and get it that there is nothing wrong with it. That " the tech is unable to verify concern, scanned for codes and bulletins and found none" so therefore there is nothing wrong with it. Next time it jumps out of gear to push the onstar button and have it towed to them and they will see if they can figure it out next time. I have a handicap son and we use that car since it gets great gas mileage to get to the doctor appointments farther away and I do not want to break down on the freeway with him. After reading that our lemon Chevy is not alone with this issue you would think GM would.

The contact owns a 2009 Chevrolet Aveo. The contact was driving approximately 50-55 mph when the vehicle began to decelerate and drive as if the contact had shifted into neutral. The contact depressed the accelerator and the vehicle was hesitant for a moment before engaging. The contact stated that the failure would occur sporadically at various speed and road conditions. The vehicle was taken to the dealer for the failure four times yet the dealer was unable to duplicate the failure each time. The vehicle was not repaired and the manufacturer was not contacted to report the failure. The approximate failure mileage was 4,500 and the current mileage was 12,000.

Driving on interstate highway in our new 2009 Chevrolet Aveo. It has an automatic transmission. The transmission shifter jumped or was slightly bumped (although I don't recall bumping it) from drive into neutral at 65 mph. Fortunately able to make it to shoulder to return to drive position (didn't know if going from neutral to drive at high speed would have caused damage). Reported problem to auto dealer who said the transmission is normal, does same thing on cobalt model! note: We can push shifter from drive into neutral at any speed without depressing the button on the shifter. Has only happened one time so far.
