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.

Driving into a traffic circle car suddenly stopped then lurched forward making a squealing noise. Again, almost T-boned. The engine light then lit and bluelink posted a message on screen that car has an engine issue and to call dealer. Bluelink roadside assistance took 7 hours to get tow truck to me, dealer would not give loaner car until they received mine - lost a day's work and car laid up 5 days. Exactly one week after emergency brake self engaged and seized wheels while driving.

While driving 65mph at 10pm on a the interstate, I heard a pound "thunk" and thought I had a tire issue, so began to steer toward the emergency lane. I quickly realized I had no power to accelerate, no power steering and the dash was blacked was dead. Only ever thing working was radio, emergency flashers and dome light. Door locks did not even work. Called for roadside assistance and car was towed. I have no further information about the car's disposition as it was a rental. It was terrifying and could have ended catastrophically in serious injury or death. The reason I am filing this report is to insure it will be investigated thoroughly. I did report it to Hyundai.
