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.

2010 Hyundai Sonata Owner Comments

Sonata 4-cyl

I was sent a safety recall letter from Hyundai stating that the stop lamp switch intermittently malfunctions. This happens to me continuously. I took it to a repair shop when I was vacationing in Chicago, as I thought there was a problem with my car, and that I might be in a dangerous road situation. They checked it out and could find nothing, but I still had to pay for the diagnosis. I have asked Hyundai to reimburse me for this since it turns out to be a malfunction, that caused me to spend money to try to diagnose. They refuse to reimburse me, even though they admit it is a malfunction on their part...but I wasn't notified of this until 4 months after being charged to try and figure out what was going on.

The contact owns a 2010 Hyundai Sonata.

While driving at night on low beams, there is a black line mid-way the windshield disrupting my viewing field. It so distracting I hate driving this car at night!! it is hazardous to my driving! had it to the dealer service 2 or 3 times to check the lights and they also drove it at night and saw the same thing. They told me it was the way lights were designed and that cannot do anything for it!! very annoying!! I also have heard from people that ride with me at night that" those lights would drive them crazy driving like that"!! I may have to get rid of this car because it is so annoying!! you need to get a solution to this problem soon!! I am one unhappy customer right now! this is my third Hyundai and I like them.....but not this one!!! this is a 2010 Sonata. Have also had trouble with the transmission as it shifts to the next gear. Had it to dealership 3 times with that!!! not happy at all with this car!!!! there is no certain dates...just an ongoing thing. The date below is when they told me they couldn't do anything more about the is the way they were!!

My 2010 Hyundai Sonata has a low beam defect that is a danger to drive at night, especially on hilly country roads. There is a black band that erases the field of view for objects on or alongside the road. By the time the car had 5K miles on her - she had been in twice to have the headlights checked and I was told they were adjusted as high as they could go and to use high beams if I couldn't see. I called Hyundai customer service and after getting nowhere I finally got a manager on the line and he promised that an engineer would be sent to my dealership and look over the problem -this never happened so when I called I was told to go back to the dealership so they could look at the lights again I get flashed by oncoming cars because they think my highs are on when they are not. I can't imagine what they see when my highs are on. If I drive under streetlights or have oncoming cars in my view I don't see the black band but what I do see is my lights bouncing off road signs with only splotches of letters being illuminated and the rest of the sign dark. If something, like a deer, were in the road or by the side of the road I would never see it. I do not want to cause an accident, kill someone, hit debris in the road or hurt myself in a crash because the lights have a faulty design.. I read that other 2010 Sonata owners are having this same problem so when is Hyundai going to do something about it and fix the problem or replace our cars? I wrote to Hyundai and they claim that the lights are working as designed and I should take my car in to check my lights if I am having problems. I had already been told by the service center during my first visit that it is a design flaw so I'm sensing a catch 22 here. I called the service center and told them I need to have a technician drive the car in the dark before closing hours. In the meantime, and until this gets fixed, the black band greatly impedes night driving and is a hazard.

I noticed this immediately after purchasing the car and driving off at night. I had test driven it for a long period in the daytime, but not at night. The headlights are either faulty or a product with very poor engineering. There is a very distinct horizontal line dividing darkness and light where headlights shine. That line jumps up and down as bumps in the road are crossed while driving. Vision with lights at night is so poor that you have to drive slower than the normal speed limit. It is very shadowy with blotchy areas of darkness to light in the range of vision. Shadows seem to be coming from everywhere; the distraction and lack of clear vision while driving at night is frightening and very dangerous. The only way I feel confident driving this vehicle at night is with the high beams on. I thought there was something wrong with my eyes before various other people with me confirmed this was occurring. I won't drive it on the freeway!
