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.

2010 Kia Forte Owner Comments

Forte 4-cyl

  • 22,500 miles


My 2010 Kia Forte ex sedan, 5 speed automatic has a transmission problem that could definitely lead to injuries or death. This is a recurring problem that can happen any time, but mostly occurs during or after going up a significant hill, but may happen on level ground. There's 23,000 miles on my Kia and it's under full warranty. I took this to the dealer, they could not find a problem or duplicate the problem; they suggested flushing the transmission for $150, so I did that. It did not help. It stopped for about a week, then it started seizing up again, today (3/10/2011) it seized twice on my wife. What it does is not actually stop the car, but "freeze" you at one speed, typically either 20mph or 45-50mph it takes up to 30 seconds to shift, and if you are pulling out in front of traffic and it seizes and won't let you go beyond 10-20mph it's very dangerous. The dealer says they won't have a replacement loaner until next week, so we'll wait. I'm in northern ut. It's happening in dry warm (50-60 degree) weather. We have not driven the car severely, this should definitely not happen. The Kia owner's manual says to inspect the transmission fluid at 40,000 and only change then if needed, so the very expensive fluid should be good. This is some unique fluid you have to buy from the dealer, normal auto parts stores don't have it. Other drivers are reporting this with the Kia Forte ex also ( I am concerned about our safety while driving a car I can't predict when it will seize up and not shift. Letting your foot off the gas does not help. It does have to be well warmed up to have this difficulty, at least 10 minutes of driving. Thanks for your attention to this matter!
