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 Amanti Owner Comments

problem #5

When I start my car, the RPM accelerates high as it will go. Very annoying and loud. It does this most of the time some times when I come to a stop light and proceed forward, the car jerks forward as I accelerate.

My check engine light comes on and my car loses power fast no matter what speed I am going. I put my foot on the gas and the RPM's go up and I am only able to drive at a speed of 20mph. At times my car will drive at a normal speed and the check engine light will be on.its very strange. I've taken it to the dealer and they said that it needed a new catalytic converter. It was replaced under warranty. One week later the same symptoms and another out of pocket expense of over $1,000 and another part. The problem still exists months later. Each time with a different diagnosis by the dealer. My mechanic diagnosed the problem when it first happened with his meter and it read electronic throttle body. I told this to the dealer months ago and thousands of dollars ago.

The vehicle surges while accelerating. The problem occurs sporadically but has done it consistently for over 5 years. Every time I take it to the dealer they can't find anything wrong and nothing is done. This vehicle has an electronic throttle.
