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.

  • 35,000 miles


The contact leased a 2013 Chevrolet Sonic. While driving 10 mph, the vehicle experienced an issue with the air duct. The contact stated that the vehicle's engine ran hot due to the pressure ratio. The contact took the vehicle to the dealer where it was diagnosed there was a tear in the air duct that needed to be repaired. The vehicle was not repaired. The tear in the air duct was between the map sensor and the throttle body. The manufacturer was not made aware of the issue. The VIN was invalid. The approximate failure mileage was 35,000.

The air conditioner makes a horrible squealing noise. It does this like clockwork every 30 seconds while running the ac on 2 or above. It is so loud even with the radio on you hear it going down the road. It started right after I hit 2000 miles on the car and about a month after buying it. It continues to do it a year later and I have taken it to the dealer 8 times, the say it is normal.

The engine coolant temperature warning light turn on my 2013 Chevrolet Sonic hatchback as I was pulling up my drive way. The ac stop blowing cold air. Liquid was dripping from the front portion of the car. The fan kept going even when after I turn off the vehicle. Turns out radiator has to be replace. Ridiculous since its a brand new car.
