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. Notes: The 2012 Kia Sedona received a poor rollover rating from the IIHS.

My vehicle has approximately 68K miles on it, and began leaking oil within the past month (and displaying the low pressure error light). The leaks themselves varied between small drips to significant amounts left in parking lots. It got to the point where I was unable to even run the heater for extended periods of time due to the fumes entering the cabin from the burning oil. With 3 kids until 12yrs, it was very unsafe. Upon bringing it in for service, I was advised that not only the oil pan gasket needed to be replaced, but the rear main seal as well. This is alarming since the rear main typically does not need to be addressed until the vehicle is over/near 100K miles. Thankfully, my warranty is covering the repairs, as this could have cost me over $1K to replace (due to the transmission needing to be removed to get to the seal).

About 18mo after owning the van we started to have issues with shifting from park to other gears. It keeps getting worse as time goes on. Now I have had to remove the shift nob and depress the linkage to get it out of and into gear.

Sedona 6-cyl

  • 22,466 miles
Key stuck in ignition. Parked mini-van, cannot remove key from ignition. While turning counter clockwise, stopped at acc position. Can turn key clockwise, restart engine, turn off engine, key would not turn counter clockwise past acc position. Took to dealer, dealer could not duplicate problem. Cost $170. 2 days after pick up mini-van from dealer, wife drove to grocery store, could not remove key from ignition. Checked internet, seems that there has been a problem going on since 2006 with numerous Kia vehicles but no technical service bulletins. I was able to duplicate it once. I could not turn key counter clockwise past acc, when I took foot off brake pedal, vehicle rocked slightly, heard click and saw gear selector lever shudder. Now could turn key and remove from ignition. I think something wrong with shifter linkage not releasing microlock in ignition.

The contact owns a 2012 Kia Sedona. The contact stated while driving approximately 60 mph the vehicle lost acceleration independently and the speed would not increase to 30 mph when the pedal was engaged. The failure occurred twice over a period of a year. The vehicle was taken to the dealer who diagnosed that the sensor for the throttle needed to be replaced. The vehicle was repaired. The contact also stated that the odometer reading was incorrect. The manufacturer was notified of the failure. The approximate failure mileage was 42,000.
