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.

2006 Hyundai Sonata. Consumer writes in regards to replacement of drive belt issues. The consumer stated there were no issues with the vehicle, prior to the drive belts being replaced. A few weeks after the belts were replaced, the vehicle was not performing well when driven. There was hardness on the accelerator pedal, there was a slight, faint chirping, faint grinding sound when the A/C was turned on. The manager informed the consumer, the noise was coming from the A/C/panel and maybe a loose flap. However, the noise continued. The vehicle was returned to the mechanic, who inspected the vehicle and discovered the belt that was installed was not the correct one for the vehicle. However, after the original belt was installed the noise was still present, but not as loud. Also, the struts were replaced due to hearing a noise when going over bumps.

The timing chain tensioner on my 2006 Hyundai Sonata was defective and caused the chain to gain slack causing the engine to fail.
