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.

2014 Kia Cadenza Owner Comments

problem #2

Jan 122016


  • 11,600 miles


The speed control brakes were triggered by a loaded bnsf container train about 50 yards to the left of and parralelling the vehicle. There was no traffic ahead of or behind our car as we caught up with this train and then there were rapid beeps from the dash area and the brakes were firmly applied as they would be if we were approaching a slowed vehicle on the road. This repeated until I turned off the cruise control. The train later got ahead of us and when we caught up with it the process repeated. No other train had this effect not has the problem recured. This was on us 84 between texico and muleshoe, tx.
