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 2011 Sonata has a seriously defective engine that seizes without warning. It was awarded the dubious honor of being the first CarTalk / CarComplaints Turd of the Week in late September 2015.

A class action lawsuit was filed in May 2015 against Hyundai that claims the 2.4L Sonata engine is defective. More info here.

Driving on the highway, went to accelerate and a loud clanking begin rumbling in my engine like something was loose and moving around. All my dash lights cut on and my speed slowed dramatically. Luckily I was in a position to get over to the shoulder before being rear ended by a truck. I wonder had I been killed or seriously injured would Hyundai still be dragging their feet on finding a remedy or replacing the engines for campaign 132. This incident occurred October 19, 2015 approximately 6:15am in mechancisville, md.

While driving at 45-50 mph, on highway, experienced catastrophic engine failure and other significant component failures, resulting in a very dangerous situation for driver, passengers, surrounding traffic, noises, smoke caution lights loss of power and control. Immediate evasive action had to be taking to avoid injury or loss of life. Once at rest, vehicle continued to smoke immensely. Low mileage, very disturbing and concerned for others driving these ticking bombs! Hyundai needs to address this issue with more strength and direction.
