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.

2010 Hyundai Sonata Owner Comments

problem #3

Hyundai Sonata 2010 V6 sedan rolls backwards on incline when in drive. Basically goes into freefall in time it takes to put foot from brake to accelerator. Also steering is very swimmy. Tend to over or under steer and lots of sway in chasis when turning or changing lanes at high speeds on freeway. Have taken to dealer multiple times and told it is the way it is designed. Sounds flawed to me.

The contact owns a 2010 Hyundai Sonata. The contact was driving approximately 5 mph attempted to park the vehicle on an incline. When the ignition was turned off the key was removed with the gear shifter in the drive position. Suddenly, the vehicle rolled down the incline into another parking space. The VIN was not available. The failure and current mileages were 3,500.

I was backing up slowly when the car suddenly accelerated without me touching the gas. I was about to put it into forward gear when it suddenly lurched backward.
