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.

2001 Hyundai Sonata Owner Comments

problem #1

Jan 282004

Sonata 6-cyl

  • Automatic transmission
  • 80,000 miles


Lower oxygen sensor malfunctioned, causing the "check engine" light to stay on. I have been returning to the suntrup dealership in Missouri every since I purchased the car for the same exact problem. And the problem is always the oxygen sensors. I have a 2001 Hyundai Sonata and I have been having the same problems over and over. I had an extended warranty that I purchased with the car for $1,300 and I find out on my last visit to the dealership that the warranty company filed bankruptcy. So now I have no warranty on my car and I have lost money for no reason.
