On a Sunday morning I had tethered my dog in the back seat to take him to the groomers. I cranked the car and realized I left something in the house. I exited the vehicle and we straight in and go the item I needed and exited my patio doors, turned around to pull blinds closed and to my amazement saw that vehicle was missing. As I turned around, I saw my vehicle traveling backwards with my dog seated in the backseat 100 ft or more away from me. There was no running to get to it to stop it. The drivers door was open and the car was headed to the main road. The door of the vehicle remained in the position I left it when I had exited the car however was stripped off the car by the cedar tree, the car went into the ditch with my dog and stopped there. The gear shift seemed to be in an odd position best I can remember and it was not in the park position nor do I believe it was in reverse position either. I was stunned and alarmed so I cannot say my memory is exact on this as I was focused on ensuring the car would not further. I was able to open the back door and took my dog off the tether. Had a wrecker get it out of the ditch and take it to the collision center where they had to replace the interior panel of the driver's door, the whole door as it was ripped from the hinges and replaced the front fender as well. Thankful this didn't happen in a parking lot where a child or elderly person, or anyone for that matter could have been run over. I hope this compaint gets some attention. The vehicle was sitting on level ground when I exited the vehicle, there was no motion to indicate the vehicle was in reverse. My car when put in reverse will not get you time to get out. You must hit the brake. I have no clue what happened. I will upload pictures of the crash when I get internet service to my phone.

Applying the brakes at a stop requires the brake pedal to be firmly held to the floor otherwise the engine will start reviving up and move out fast if the brake is released. Also appears that the transmission when moving the shifter to park does not mean the car is in park. I did this once in a store parking lot. The shift handle was in park. But as soon as I took my foot off the brake and opened the door car took off. Caused $ 6,700 to fix all the damage. Engine does not come off fast idle. When I first got the car. Idle RPM was between 500 and 750. Now the idle never goes below 1200-1300 RPM. I tried various brands and grades of gas including ethanol free unleaded but nothing helped.

2015 Sonata sport 2.0T, 23800 odometer. I noticed a sound that sounded like the blower fan at max. Speed setting, when I accelerate. Investigated and found the air hose assy. Between the air filter box and the inlet of the turbo was disconnected from the turbo inlet. Upon removal. The hose was melted thru. I purchases a replacement hose from zimbrick Hyundai East in madison wi and found out that the replacement was of a different heat resistant material and ask the service manager if this cost is covered under warranty. It was not because I was replacing it myself. I called Hyundai customer service and there confirmed this. Why won't Hyundai warrant an oem part that was changed to an alternative material, after the product was released to the consumer, regardless who installs the part onto the car? the vehicle was stationary, and inside a garage during the removal and installation of the air hose assy.

Takata recall my husband bought the 2015 Sonata on March 9, as we were driving home we vented the sunroof and next thing you know it made a loud noise and flew off the car. We immediately stopped to go back and find it and the glass was completely shattered.

Sun roof squeaking. Brought the car to dealer twice for this issue. They temporarily fix it by lubricating. Issue has come back so bad that it sounds that the car is falling apart. When I push up on the sun roof or I open it it disappears.

The vehicle began making a knocking noise while driving up the mountain to big bear. No warning lights illuminated on the dash. Two days later while descending the mountain, the vehicle continued making the noise. No lights were illuminated on the dash. Then, while still on the mountain, there was a loud "pop", smoke could be seen in the rear view mirror, and the engine died; I coasted to the side of the road. The car behind me pulled over and the driver yelled that my car was on fire. Flames could be seen under the car. The fire spread and ultimately the car exploded, setting the hillside on fire. The fire department extinguished the fire and the car was towed away.

When it rains, there is water intrusion inside the doors. There is so much, that I have to manually dry it to prevent mold from building up. I cannot even keep the doors open to let it dry since the dashboard light for open door remains on when doors are open and this drains the battery. Service dept. At Hyundai explained to me that this is due to the opening around the doors. There is a space that is quite large for the water to enter. I believe this is a design flaw. They should replace the weatherstripping if mold develops and charge me nothing to do this.

My engine hood has come open on the freeway twice in the last week. The dealer said there was nothing wrong after the first incident, then it happened again. The alarms and warning sounds that go off when this happens are so loud and distracting I lost track of my driving trying to figure out what was going on.

My 2015 Hyundai Sonata limited sport 2.0 has a defective glass roof. The glass panel was very loose upon delivery of vehicle and made noise 100% during driving. My local Hyundai dealer had a 3rd party vendor attempt a repair. The noise went away but now the glass panels don't fit anymore and the trim around the glass is failing.

On July 12,2016 I was pulling into a parking spot at the bank. My foot was on the brake as I entered the space. My car then seemed to make a loud noise like the engine was revering ups it then shot forward like a rocket. It felt someone had smashed behind me! luckily there were pillars in front of the bank which prevented my car from crashing in the bank. I have found several complaints with the 2015 Hyundai Sonatas doing this however there is no recall. Cost of damage was $9,051. This was an extremely frightening experience!

I was parking my 2015 Hyundai Sonata turbo sport in a strip mall parking lot. I pulled into the space and, before getting in all the way, the car suddenly accelerated to a high speed, jumped the concrete curb and slammed into a concrete wall. The air bag did not deploy and my chest hit the steering wheel and my head whipped back so I now have headaches, neck and back pain.the front bumper was damaged with marks from the concrete and though it remained on the car, it was dislodged. There was also some damage around the front headlights and the rubber part of the undercarriage.

In the snow, my Hyundai Sonata will drive fine until turning. During turning, even with minimal snow, my brakes lock up and my car slides slowly but at that point I am unable to do anything, usually making me hit a curb. This has happened twice in the last two weeks costing me $2200. I have had two cars before my Hyundai Sonata and haven't had issues with such a problem. The mechanic scratches his head in confusion as to how almost the exact same thing happen in such a small time frame. It is a major safety issue, I believe something with traction control or braking is wrong. Had I been a worse driver the damages could be worse.

I was admitted into the hospital, where I had surgery and was told I had a hemorrhagic stroke. October 2015, I had 2 more strokes and surgeries. I never had a history of strokes, and was wondering could this be a part of an environmental issue with the chemical exposure from the new vehicle? any useful information would be greatly appreciate.

The primary purpose of filing this report is to prevent a child from dying in a locked trunk. As I packed my rental car for a trip I stupidly locked my keys in the trunk of the car. An unlocking service came and popped my door lock but because the alarm system was on there was absolutely no access to the truck at all. This model has drop down seats but are locked from in the trunk. It took a couple of hours for someone to correctly tell me to open the trunk I had to visit a Hyundai dealership for a key....no other way to enter the trunk. I often drive across the desert...no dealership and no unlocking services. If my grandson had played in the trunk and locked himself in he would have died of heat exposure before it could have been unlocked. This is unnecessary. There are release levers in the trunk but a young child would be unable to pull them. This is a tragedy waiting to happen. I was saved only by the fact I was in a very large city.
