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.

Had been experiencing rough idle despite fuel system cleaner and clean throttle body. Removed and cleaned idle air control valve with throttle body cleaner, which smoothed out rough idle but stuck throttle at high and increasing RPM (getting louder) in park gear when parking after driving. Suspected and replaced throttle position sensor but it was electronic, not spring activated, and continued to experience same high rpms before parking. Was driving on 50 mph highway with traffic lights (rt. 50 in Virginia), came to a red light and could not stop car---rpms increased while in drive gear despite brakes being all the way to floor. Would have run through red light at high speed if had not shut off engine before intersection. Replaced with new aftermarket iac (idle air control valve) and have had no problems since.

On this date I experienced the 4th of 5 incidences of unintended acceleration in the 8 years I have owned this car. I was driving in daytona beach approaching a red traffic signal. There was a car stopped in front of me. When I applied the brakes, the car lurched forward and the acceleration revved the engine. I had to turn off the key to stop the car in heavy traffic. I pulled off the road and removed the floor mat as had been suggested by the service technician the last time I had taken it in for this issue. I drove it home safely, but the next morning in a grocery store parking lot when I applied brakes to stop, again the car lurched forward almost hitting a BMW. I again drove it home safely, parked it and called the dealership. I made arrangement to take it in on July 7th to have it looked at again. Out of fear for the safety of myself and others I had the car towed to the dealer. They kept it for 2 days, drove it 240 miles and once again could find no issue. The car is parked in my driveway out of fear of killing someone or damaging property. When I told them I had found multiple instances of this happening with Hyundai online, they claimed to have no knowledge of such a thing. One article stated that the manufacturer fixed this problem in 2012. While I cannot afford to purchase a new car, I am afraid to drive this one, and would not want to sell it to anyone else because of the safety issues I have experienced.

The contact owns a 2006 Hyundai Elantra. The contact stated that while attempting to park, the vehicle independently accelerated. The contact abruptly depressed the brakes however, the vehicle lunged forward and crashed into the leg of a pedestrian. The contact quickly shifted into reverse and then back into drive, and the vehicle lunged forward again and crashing into the pedestrian a second time. The pedestrian sustained a bruised leg and swelling of the leg and ankle. A police report was not filed. Neither the dealer nor the manufacturer was made aware of the failure. The vehicle was not repaired. The failure mileage was 27,000. Updated 07/16/14

While applying the brakes, the cruise control does not disengage. I experienced this as the car "lurching" forward when braking, as the engine is trying to bring the car back up to the pre-set speed. This happened, most recently, while on the freeway in rush hour traffic. The sudden lurch was frightening since it was unexpected. The lurch almost caused me to make contact with car ahead of me. Luckily there was no accident. Even with multiple presses of the brake the cruise control did not disengage. It was only by using the hand controls was I able to turn off the cruise control. This has happened at least 2 times, but unfortunately, I cannot recreate the problem systematically.

While backing up in reverse, the brake did not work. Instead the car accelerated and the engine reved up to what seem to be a very high speed. The car stopped when it smashed into our other car, which was about 4 feet behind it. It was about 5 pm on a dry road. My husband was wearing work boots at the time. There was only a few scratches on the rear bumper. The hood of the other car was pushed in. Our mechanic could not find computer codes or any other problems. The Hyundai dealer also said there were no issues he knew of. Other acceleration problems with Elantras we read about make us think the brake and accelerator design on these cars are too close together. They seem to be only about 3- 4" apart, where other makes are at least 6" apart. We believe his boot may have gotten stuck on the gas when switching to the brake. This also happened last winter when our 2000 Hyundai Elantra was backing up and would not stop. It was stopped by a snowbank. My husband was also wearing snow boots at the time.

On the afternoon of 2/19/2011, was driving above vehicle. While adjusting into a parking space (going very slowly), car suddenly accelerated to top speed (140 mph?) I then attempted to stop car by driving on the nearest sidewalk to avoid hitting cars on street. At this top speed I crashed into a chain link fence tearing it down and then turned and finally stopped by hitting a tree. My air bags deployed but car was totaled and I was taken to a nearby hospital in northeast phila. With severe injuries. My right arm was broken in two places requiring surgery and my ribs were severely damaged. Both legs were extremely bruised. I spent two weeks in two phila. Area hospitals and then a month in a nursing home in warminster, pa. Until I was able to walk without assistance. Am still required to use a cane.

The contact owns a 2006 Hyundai Elantra. The contact was driving approximately 50 mph with the cruise control activated. The brakes were engaged but the cruise control did not deactivate and the vehicle would not stop. The vehicle came to a stop once the cruise control button was engaged. In addition, the exterior brake lights would not illuminate. The vehicle was taken to the dealer where recall repairs were performed under NHTSA campaign id number: 09V280000 (exterior lighting) yet the exterior lighting and cruise control failures recurred within a year. The dealer was contacted and advised that because the vehicle was repaired once for the failure under the recall, any further repairs would be at her expense. The contact stated she was unaware the repairs that were performed where for a recall. The vehicle was not further repaired. The approximate failure mileage was 50,000.

My 2006 Elantra hatchback has a sudden acceleration problem. I experienced several times that my car suddenly accelerated while normal driving, for example, I was driving at 40 mph but the car sudden ly accelerated to 60 mph. On 1/25/2010, I was driving home at 2:30 am, setting the cruise at 70 mph and the engine speed was showing the engine was about 2750 RPM but it suddenly accelerated to 4000 RPM and the car was hard to control if I was not paying attention to it. I turned off the cruise setting at once, later I turned on the cruise again to set at 70 mph and later it suddenly accelerated from 2750 RPM to 4000 RPM and then slowed down back to 3000 RPM and again accelerated to 4000 RPM then back to normal speed at 2750 RPM. Also, my car could not go forward straightly, it always goes to the left side. I have to turn my steering wheel to the right in order to go straightly.

On my 2006 Hyundai Elantra gls 4cyl engine there is a issue which I have brought up 3 times now to Hyundai & all they keep doing is resetting the computer & trans retrain reset. The issue I am having is at a steady speed off 25-30 miles hour I get a very bad bucking & jerking effect the loss of power shortly after the bucking & jerking happens that the car looses power some much so it doesn't want to move fast enough to keep up on the highway when coming off a off ramp merging into the highway traffic two times the last time was today this all happened again & I couldn't get the car to move fast enough to flow with the regular traffic that I almost got hit by a 18 wheeler truck today. This problem is making the car not safe to drive & I am afraid if I continue to drive it like Hyundai wants me to do in this condition to try to bring the check engine light on to see what the problem is I might get hit by someone & possible killed. This issue is a serious operating condition that warrants someone doing something about this problem & this is a common issue from other Hyundai Elantra owners of the same year or newer I have read online & Hyundai hasn't addressed it well enough or come up with a fix as of yet. Telling a customer to keep driving the car in this condition is not safe just some the mechanics can get a check engine light on with a code to go on. This car almost always feels like it is going to loss total engine power & just cut out on me while I am driving somewhere & I will get hit.
