On 10/08/2009 my 209 Hyundai Sonata went into an unintended acceleration. As soon as I put the car into drive it began to accelerate. The brakes did not work and I was able to shift into neutral. I was on a narrow dirt road with little limited options as to where to steer the vehicle. I missed a boulder, garage, and tree before hitting the side of a house. The ambulance was called and I was transported to the local emergency room. I had a concussion, fractured knee along with a number of bruises and abrasions. The emts told me how lucky if was since the air bags did not deploy.. an internet search, including your website, notes these problems going back several years. Toyota had the same problem and did a recall. My injuries will exceed the limit of my insurance and I will have to purchase a car. I know how lucky I was to walk away. I am sure others had more serious injuries and higher expenses. What does it take to force Hyundai to do the right thing?

Upon accelerating up an entrance ramp to the highway, car accelerated at an unreasonable rate of speed tried using brakes, but they were gone. Car hit speeds of 60/65 mph for more than 3 miles on a turnpike. Parking brake did not work, brake pedal was down to the floor and I could not control the speed of the auto. After traveling more than 3 miles, in the shoulder, I put the gear into neutral and the car began to slow down and finally stop. Towed from turnpike to dealership. Know there have been problems with the 2006 model, but is there anything similar to my experience with the Sonata 2009.

The ESC light has been going off intermittently in my vehicle for the past 2 weeks, causing the shifter to downshift instead of keep moving the car when I press the gas, and the gas pedal becomes unresponsive. This happened on the interstate (I-78) today, and I almost got into an accident in the middle lane. I researched the problem, and it seems there was a recall on previous Hyundai models, yet Hyundai has failed to address this issue in the 2009 Sonata. There needs to be a recall regarding this issue. It is very dangerous, and could be related to the crankshaft sensor or a number of things, but bottom line, it causes the car to become unresponsive while in motion, and the driver needs to pull over, shut off the car, and turn it on again for it to maybe work, maybe not. This is a horrible headache that needs to be addressed, and I am sure that I am not the only Sonata owner with this issue. Here is evidence: www.sonataforums.com/forum/Hyundai-Sonata-engine-technical-discussion/1906-ESC-off-light-comes-intermittantly.html so please get it done and issue a much needed recall for this major safety issue before someone gets hurt.

Basically it appears that I'm having the same brake switch issue common with many Hyundai. However, currently the '09 Sonata is not covered under any recall. The problem began at least a year ago when the ESC off light would turn on at random times. It would normally clear upon turning the car off. A few days ago the ESC off light would not turn off. Today I could not shift into park from drive. After searching the internet I quickly found the brake switch issue. I confirmed that my brake lights were not functional. This is something occurs with absolutely no warning which is a bit scary since I drive home on a major highway. I'm not sure how long the brake lights had been out. I also noticed that the cruise control stopped functioning when the ESC off light became permanent. However, for some reason it started working again when the shift lock problem occurred. Odd. Not sure why an additional issue would make the speed control functional again.

Some times when starting the car with my foot on the brake the rpms go up to about 1200 and then down to 800 rpms. When my foot is removed from the brake the car wants to accelerate and go on its own often. While stoped at a stop sign or stoped with my foot on the brake the car will lurch forward when released, some times spinning the tires. It is progressively getting worse after returning from a 5000 mile trip in June, 2013. The car purchased new and has a automatic transmission with aprox. 65000 miles total on the car. This is a accident waiting to happen and should have a recall.

While driving home, I braked to turn into my neighborhood and was almost rear ended. My friend whom was following me stated that my rear brakes did not come on when I brake. I attempted to park my vehicle and I could not put the car into park but only neutral, nor could I shut off the vehicle. The key would not turn to shut off the vehicle. I had drive the car to a friends garage, place the car into neutral, detach the battery in order to have the vehicle shut off.

I was driving the Sonata when all of a sudden the car lost its force and wouldn't move. While stuck in the middle of the street I was pushing the gas peddle but the car would not go. The ESC off light came on, and the check engine light as well. I powered the car off and turned it back on but the car still did not have a lot of force, but enough to get to a nearby parking lot. I left the car off in a parking lot for about 5 min and turned it back on. The ESC light turned off, but not the check engine. There have been similar problems where its a switch in the brake peddle but that should not make the entire car shut off. I took it to my dealership since I just bought the car 2 weeks ago and now I'm waiting for diagnostics to come back.
