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.

2003 Kia Sorento Owner Comments

problem #2

Nov 122007

Sorento Lx 4x4 V6

  • Automatic transmission
  • 75,000 miles


There's no excuse for this to happen. I consider it a Mfg. error and Kia should offer the tank free.

problem #1

Apr 202007

Sorento EX AWD 3.5L

  • Automatic transmission
  • 61,500 miles

Heater would make a gargling sound like there was air in the system and there was no heat and the temp gauge would rise towards the hot level. Fortunately it was cool out and the ramp air kept the engine cool. Called KIA service and the mechanic told me to check the coolant overflow tank. It was empty. He said it probably has a crack in the bottom that is was a known problem. Did not see any coolant on my garage floor so I was puzzled (you could eat off my garage floor). Mechanic said you would not see any leak as it only leaks when warmed up and leaks onto the exhaust manifold so it would evaporate. Of course it happened 1500 miles after the 60k warranty. So I had to eat the cost of the part @ $95 which wasn't too bad.
