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.

2004 Kia Sorento Owner Comments

problem #1

Mar 122004

Sorento 6-cyl

  • Automatic transmission
  • 1,500 miles


Since purchasing new 2004 Sorento in February 2004, have had the vehicle to two different dealers for five attempts to resolve a vibration from unidentified source. The vibration was first experienced at 70 mph. One dealer has replaced the gear cluster in the rear differential, balance and rebalanced tires, replaced rear U-joints, and replaced front drive shaft. This did not correct problem. Second dealer replaced rear drive shaft a second time. Vibration is now worse. It can be felt at 50 mph and 70 mph. Have met with Kia factory rep. Kia states they have a technical bulletin on this problem.
