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.

Delays in acceleration linked to a computer program that controls the transmission, shifting from 1st to 2nd gear automatic transmission, there may be a 2 to 3 second lag in acceleration due to the transmission control module programming or transmission.

Sonata 4-cyl

When vehicle is cold and I decelerate down thru 20 mph, the transmission down shifts abruptly causing a jerking motion. I have been told by an auto mechanic who researched it that there was an actual recall by Hyundai for this issue. He said the problem was that Hyundai installed computer control equipment from an older model in their 2010 Sonatas and this resulted in a failure in proper communication between the computer and the automatic transmission's solenoid, causing the abrupt down shifting at 20 mph when car is cold. One last note: When this first started occurring, it would cause the "fix engine" light to come on, but this has not happened for about the last three weeks. The abrupt down shifting when cold still occurs consistently, always right around 20 mph.
