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.

I was driving from Rhode Island to North Carolina and when I was driving West across the tappan zee bridge near New York city and had gotten to the other side of the bridge, I lost throttle response. The car began to slow down in heavy traffic and I had to cross three lanes to get to the right hand lane. The check engine light was on steady at this point. By the time I reached the right hand lane, the car was going only about 35 mph and I was very lucky that I was not hit by other vehicles on the bridge, who were dodging me at high speed on both sides.. this was a very scary situation and could easily have resulted in fatalities. Fortunately, there was an exit on the other side of the bridge and I managed to get off I287 and find a place to stop. I checked the internet and found reports that other people had experienced similar events and that the car returned to normal after turning off the engine and restarting it. My wife, who was with me, recalled that something similar happened to her 2004 Hyundai Santa Fe several years ago when it was driven locally by one of my sons. So after about 20 minutes, I restarted the car and found that throttle control had returned and we continued on our way. After stopping to eat later in the day, and returning to the car, the check engine light had gone off and has been off ever since. I managed to return to Rhode Island yesterday without any further problems, but am now afraid that this might happen again and that I will not be so lucky the next time. I have not had time yet to have the dealer check out the car, but plan to do so as soon as possible. This is clearly a serious safety issue and I am surprised that there has not been a recall to fix this problem, especially considering that it appears to be something that has been happening to Hyundai cars, (and possibly others), for some time now.

"I was subjected to a sudden acceleration last night while driving my 2009 Hyundai Genesis 4.6. I left a full stop and sighted another car speeding toward a stop sign coming from my left. To avoid being broadsided I swerved to avoid and my accelerator jammed. I sped across the street and into a landscaped area. I hit a tree at that point which brought my vehicle to a stop. The driver side air bag deployed and I was wearing a seat belt. I sustained some impact injuries that appear to be of a minor nature. A lake was located just beyond the tree and I deliberately selected the medium size tree as a target. I was fortunate. I sustained a back injury some years ago and drive with two feet - one for the accelerator and one for the brake. There was therefore no chance that my foot slipped from one pedal to the other.

The contact owns a 2009 Hyundai Genesis. While attempting to stop for a traffic light, the vehicle accelerated independently. As a result, the vehicle crashed into the rear end of another vehicle. No injuries were reported and a police report was filed. The manufacturer was made aware of the failure. The vehicle was taken to the dealer. The technician replenished the brake fluid and was unable to diagnose the failure. The failure recurred on three different occasions, all involving a crash without injuries. The manufacturer was made aware of the failure. The failure mileage was 80,000.

This has been an ongoing issue, I have filed at least 4 complaints concerning a "soft pedal " issue. The dealer has inspected my vehicle recently as well as Hyundai America and I am still awaiting a response as to what was found. The vehicle was inspected on 1/22/2014. Note on service invoice states " dpsm has been out to drive and inspect vehicle. No person from parkway Hyundai can give any further information. This is a matter for Hyundai motor America." It has been 5 months since the inspection and hma has still not contacted me. I don't know what is going on with this website but it nolonger shows the Genesis under Hyundai if searching for complaints, recalls or investigation. As we approach this holiday period I hope that there are no serious accidents as a result of the "soft pedal" issue as well as a read collision at low speed that triggers the head seat restraint to deploy and throws both front seat passengers forward and the seat belts won't deploy at this low speed. Just another complaint that hasn't been address. Is the NHTSA overloaded with all the recalls from indication over the years. GM as an example.

While driving at 65 mph in 4 lane I-95 rush hour traffic, the check engine light and the ESC light both came on and the car would not accelerate. Pressing on the gas pedal had no effect. I turned on flashers and drifted my way through 3 lanes and pulled over and restarted the car. The check engine light came on but not the ESC light. The car ran a bit rough with the check engine light on. The exact same thing happened the next day. I took the car to the dealer, and they replaced the throttle position sensor. Based on owner reports at the Genesis owners web site, this has happened to many owners of 2009 V6 Hyundai Genesis. This is very dangerous, and the car should be recalled to fix this potential deadly situation. If I had been driving in the left lane of a highway, a serious accident with potential deaths could have happened. I had to pay 325 dollars to have this issue fixed since it has not been recalled. Please work with Hyundai to ensure this major safety issue is recalled urgently.

Driving on the freeway and the throttle just cuts off, no throttle power. Car is still running. Quickly had to pull over on to the side of the road and had to shut car off and then restarted it. It worked but it continues to happen. It happened seven times in one day, with my child in the car. At one point there wasn't a shoulder to pull over to I had to stop in the middle of the freeway. Hyundai has no recall for this issue. I find that strange since this could be a serious issue. The ESC and check engine light comes on.

Traveling to Indiana from North Carolina on the 6th of May 2011. On a rural road traveling approximately 55 mph, all of a sudden the engine light and ESC warning lights came on. After that when I pressed on the accelerator, there was no power. Electricity was still there and the engine was still on, but no power from the gas pedal. I had to turn the emergency lights on and moved onto the side. I was lucky because there weren't many cars around. It would have been pretty dangerous if there were cars around and my car suddenly stopped. I was able to turn the car off and restart. When I restarted the car the engine light remained on but I had regain the ability to accelerate. I pulled into a hotel and called Hyundai. The closest dealer was gaddis Hyundai of muncie, Indiana. The service department was closing but I discussed with technician. He indicated that it was common problem with the throttle sensor. He indicated that he would be able to fix it Monday, but that if the light went off and it was running ok, it may never happen again. I told him that I need to be durham, nc on Monday. He indicated that if it happen again. To turn off and restart and it should reset. On my way back from Indiana to North Carolina I stayed in the right hand lane. On 4 separate occasions the vehicle lost power and I was unable to accelerate. Each time I was able to pull over to the side of the road, turn the vehicle off, wait a few minutes and then restart and continue. The car is currently at the stevenson Hyundai dealership in jacksonville, nc. Here is a forum web site that reflects similar problem identified on numerous occasions related to the Hyundai Genesis V6 and V8. www.genesisowners.com/Hyundai-Genesis-forum/showthread.php?T=4459.

While the vehicle was idling or in low RPM it would start to sputter as if it was going to stall. I returned the vehicle to the dealer and it was a fault throttle sensor.

Lost complete ability to accelerate on highway traveling at 70 mph. No warning, happened twice more before I got it back to a dealer. Car did not shut off but would not accelerate. Restarted after I managed to get off in the breakdown lane. The car would go another few miles and konk out again. I immediately went to the closest Hyundai dealer. They said it was a throttle position sensor. Could really have been fatal.

While driving the car, the engine loses power. Engine and electrical systems still running but when pushing the accelerator, you get no response. This has happened twice within the last 5 days. We have called and setup an appointment with the dealership, but the earliest appointment was this Friday. Luckily we were not in heavy traffic or a serious accident could of occurred.

When I was trying to enter an expressway from an entry ramp, I stepped on the gas and got no response. The engine did not rev up as it would if the car was in neutral. I coasted to the apron, turned off the car, and restarted it. The gas responded normally after restarting but the engine light stayed on. I took it into the dealer and they reprogrammed the engine control unit, which, so far, has fixed the problem. I was told that the computer just lost track of the accelerator position. While this is not quite as dangerous as Toyota's problem, it could still get someone killed if they are trying to pull out in traffic and gets no gas response. On the Genesis owners forum there are at least 2 other similar incidents that have been reported. I wrote to Hyundai to report this issue and they responded that they would log this incident. However I do not know when they send info to NHTSA.
