Car will not shift out of park- was parked and went to shift into reverse and it would not shift, called mechanic used shift release button to get out of park, brake lights do not work, cruise control doesnt work, ecs light stays on. Took car in for recall, they sold us the brake padal switch that I thought was the recall but they said would solve the problem and it did not solve the problem!!! this is my 17yr olds car and I am very nervous to have her drive this car now, but it can not be until we figure out brake lights!!

I was driving with my daughter and took a wrong turn ending up on a dead end street on a hill in sonora. When I put it in reverse turned around then started going forward my entire car and brakes failed without warning. I quickly through on the emergency brake that stopped me from hitting a tree. Thank god it happened there as the next morning I would have been on a 2 lane mountain highway with all 3 of my daughters on a holiday weekend and it could have been fatal. My car has had all services and had just been serviced recently there were no issues and no recalls

Reference NHTSA recall 15V75900 ie. Brake pedal stopper pad my vehicle has this exact issue, however was manufactured just after the recall period and thus I was told by Hyundai that it will not be fixed. Obviously, the recall needs to be extended to vehicles made after the April 2011 date.

Hyundai break switch, Hyundai break lights, sunroof, air conditioning break switch gone out four times. Took to savannah Hyundai to be fixed. No fix as car continually does not accelerate in the middle of nowhere - on the highway or when getting ready to pull out in front of traffic - very unsafe. I have contacted Hyundai Corp concerning this issue since 2015. Savannah Hyundai service manager mike told us that we were not allowed to return for repairs because they got frustrated trying to figure out. Break light never works. Had this repaired 3 times. Savannah Hyundai put new sunroof on. Four months later it wont open or close. We have paid for everything over and over and over using our extended warranty and copays. Even if Hyundai or savannah Hyundai previously fixed something and it was even within 90 to 120 days that the repair was bad, they never offered to fix without charge. Always made us repay full deductible and costs.. car does not turn on air conditioning system intermittently. Trips get awfully hot. Sometimes starting up car and restarting fixes. Savannah Hyundai never able to fix. Savannah Hyundai has reported on two occasions that our car has serious electrical issues. They believe this is related to sunroof and brake light. This car has been having issues before 60,000 miles and stil lhas under 90,000 and same issues repeatedly. This car is not safe!!!!!!!!!!!!!!!!!!!!!!!!!! car is unsafe. Currently emailed david zukowski of Hyundai, other Hyundai outlets, message hyunda on fb. Unresolved.

The engine oil pan was resealed five times and still its leaking. When they resealed the second time, they replaced the oil pan as well. After that it was resealed three more times and the car is at the dealer for sixth reseal. They are replacing the pan again. The brake caliper pistons are exhibiting excessive rust which I have not seen in my life while owning and maintaining various cars. The field engineer is saying that its normal and I don't agree with that. What I have seen based on that it's a design flaw. The caliper piston should be pressing completely against the brake pad surface area where as small portion of the caliper remains in non contact with the pad and the salt and slush during the winter gets into it making it rust which will impede the braking operation in future and may cause a fatal crash. Attached photographs are showing pack rust inside the piston on both the driver and passenger side.

The vehicle has a history of losing power completely. At this point I am unable to enter the car with the keyless entry, you have to do it manually. The car was parked on the street. Once you put the key in the ignition the horn/alarm goes off and doesn't stop. It also seems to be revving while it is in park. While driving I experience little power surges from the car where it accelerates with me trying to do anything. There was also another instance where the car would not start once the emergency brake was engaged. Once disengaged the car started with a little hesitation. I only had the car for 6 months and have had to bring it back to the dealer at least 6 times.

On more than a dozen occasions since purchase, the vehicle has neglected to accelerate when the gas pedal is depressed nearly causing me to be hit by oncoming traffic. Additionally, the vehicle has slammed on the brakes at high rates of speed when the driver was barely applying pressure to the pedal; almost causing the vehicle to be rear ended. The vehicle has been inspected by two Hyundai dealerships for the issues; of which they claimed to have replicated. Both dealerships stated that it was normal behavior for the vehicle and there was nothing they could do to make the issues go away.

My car caught fire while being towed by my motorhome in South miami, fl on route to key West, fl. A South miami, fl Hyundai dealer repaired my car but did not replace all the parts paid for by my auto insurance company. The repair shop did not keep the burned parts as requested by me and my insurance company representative. Later, another Hyundai dealer completed the repairs as authorized by Hyundai usa after numerous communications with me, but the Hyundai dealer would not provide me with the burned parts as requested. Hyundai did not report that a fire had caused the damage. Not sure if Hyundai usa or its dealers have requirements to report fires in their vehicles. I have names of contacts with Hyundai usa in ca. I have the burned TPMS sensor not replaced by Hyundai, but paid for at my expense to a tire store in my home town. I have pictures of my car on fire; pictures of the burned parts on car in possession of my insurance company representative; I have receipts from the South miami Hyundai repairs, and I have receipts from the other Hyundai dealer for parts needing replacement but not replaced by the South miami Hyundai dealer but paid for by my auto insurance company. I also have a receipt for replacement of the burned TPMS sensor by a tire store in my home town. I filed a complaint against the South miami Hyundai dealer with the local government Agency responsible for licensing auto repair shops in that county.

On Jan 26 my husband was driving home and the road conditions were slippery. When he went to apply the brakes, he heard a loud pop and the brake went all the way down to the floor and would not come back up. Luckily this happened around the corner, but by the time the car made it into the driveway the brakes were smoking. I had to have the car towed to the mechanic. We had to replace the front brake pads, calipers and rotors. Also the brake switch oem had to replaced. When all said and done the total cost came to $729.64. Can I tell you how disappointed I am in this vehicle?? this vehicle is only a 2012 my high beams don't work nor does the cruise control. I am starting to think this car is a real lemon!!! at this point I would like to know if the brake system has any recalls because my bill was extreme and should not have happened on a 2012. I do not have the VIN number on me at this time. Very very disappointed and have nothing good to say about this car!

The contact owns a 2012 Hyundai Sonata. The contact stated that after parking and turning off the vehicle in her residential garage, the vehicle started rolling backwards. In an attempt to stop the vehicle the contact fell which caused her to scrape her chin needing 10 stitches. The contact was taken to the emergency room. The failure mileage was 39,000. The consumer stated she and the police attempted to piece together the scenario, that the vehicle was not in park, when she turned it off. The consumer stated the vehicle could be put into any gear, and it could roll, whether it was on a flat of hilly surface. Updated 08/20/14 updated 8/27/14

When I applied break my RPM idle goes up. I don't know if that is safe I show in other car RPM goes down. I took to dealer got oil change. And I asked why this happens. He told me to chack eco system. I chack eco system it was on off postion. I ask him when I bought car I never show RPM go up when I hate break. There no engine sing comesup on dashboard either. This really safety concern for my family. RPM should not go up when U hate breaks. It's should bring RPM down. RPM should go up when U hate gas padel. I get this. But when I go to any speed. And tried to applied break it should drop RPM should not go up.

When I was braking, the passenger front brakes made a horrible metal on metal sound. I had a mechanic look at the brakes (to far from a Hyundai dealer). The mechanic could not find any problems. This. Has gone on for months. I had the brake pads replaced even though the original pads were still good. I finally took my car to the Hyundai dealer who explained to me (the rotors were extremely rusted and needed to be replaced) what, this sounds like a manufacturing issue. No, I had all rotors replaced and new brake pads all the way around. Guess what, still making the sound in the front passenger side.

While driving at a low speed, approximately 30 mph and slowing to a traffic light, the entire electrical system on my 2012 Hyundai Sonata gls failed. I lost the power steering, braking and gas. All of the warning lights lit up on the console. Luckily I was able to allow the car to come to a stop on its own - if I had been traveling at a higher rate of speed, or if someone had been crossing the road, the result could have been much, much worse. Once the car stopped, I put it in park and the lights stayed on. I turned the key to the off position and then back on and it turned right back on as if nothing happened. The car was then towed to the dealer and was in service for 5 days, and they claim to be unable to replicate the failure. Since they are unable to replicate, and lemon law state that an issue must occur 3 times, I have no course of action to take besides buying a new car and taking on added expense, or driving this car, which may or may not be safe from defect and hope it doesn't happen again. I will file a complaint with Hyundai as well.

There are actually 2 issues going on. First off, I purchased the car new in September 2011 (to replace a GM lemon) and ever since I've had the vehicle, it has pulled to the right. Second issue, I left work pulling onto the road, drove a couple of blocks when traffic had stopped at the upcoming light; therefore I had not completely built up speed to the speed limit (40) when I had to stop. I applied the brakes and did not completely stop before hitting the Toyota 4runner in front of me, I felt like I was driving on ice. When I hit the brakes, the car started to stop but the brakes kept going further down to the floor, with no feeling of stopping. The dealership that repaired the vehicle through the insurance company( GM) said they did not find anything wrong with the brakes so I took it took it to my local Hyundai dealer, who did find that my brake lines had air in them. I don't know how since I had never had them worked on and it's a sealed system. After the technician called Hyundai, they assigned a case number. While my car was being repaired, I mentioned that the car pulled to the right so they did an alignment on it, since it was a front end crash. They did notice the pulling but the alignment did not help and thought I may have a bad tire, but with 21,000 miles, would not replace it. I get my tires rotated faithfully and have already been told they are wearing out. This is the first foreign car I've owned and (as prev. Noted) got it to replace a GM lemon, now I don't feel safe driving this car and I have to use it to travel across the state. Between the steering and the brakes, I don't know what to do. Did I get another lemon? since I can't seem to get any satisfaction, I'm contacting you, I'm tired of calling the Hyundai dealer since they say can't do anything. I don't want to get satisfaction, only after my family is writing my obituary. [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).
