On Dec, .21st, 2017 I entered a business parking lot at low speed as one would enter a parking lot and within a few feet turned right to enter an aisle between 2 rows of parked cars. At the second right I had my foot on the brake to slow but realized my car was not slowing, maybe even accelerating and then, horrified, realized my efforts to slow or stop were futile! I swerved to miss a person and fishtailed hitting a bumper of an unoccupied car. By then I was nearly T-bone to many cars on a busy street. Still not able to stop I made an abrupt turn to the right and was fortunate (yes, fortunate) to hit a retaining wall around business signs in order to stop the car. Thru these frantic very few seconds as I was trying to stop, my foot was on the brake, I couldn't pump it as one would expect to do and the vehicle seemed to be accelerating. My choice came down to hit many occupied cars on the street or turn and hit the retaining wall. Again, how fortunate it was there!! airbags didn't deploy; the car is a total loss. This is a very frightening experience. Could it be that other drivers of the Hyundai 2015 Sonata have not lived to tell what happened?

I left harrisburg to drop 3 students to state college, driving for uber on 09/29/2017.around 9:30pm in lewiston in mifflin county, we came across a short turn.I got a kind of sudden small speed. We were out of the road. I tried to stop and put the car back on the road, too late. We hit a mountain and the car was lying on his right side.thanks god nobody got hurt; just chocked and some scratches.after reading the documents my insurance company sent to me, I realized there were a recall on my car for two problems.my car used to have this small speed sometimes I didn't know why. Hyundai motors sent me a email on October 26th to let me know about the recall; too late we already got crash. I want to say that my last inspection was at Hyundai but we didn't tell me about.

I was on a city street approaching a red light, as I was coming to a stop my car's engine shut off without warning. Oil light, check engine light, and battery light were illuminated. I put my hazards on, put the car in park and attempted to re-start the car with no luck. Car did not make any turning over sounds when trying to re-start. Dashboard lights, radio, powers windows still worked. I called roadside assistance and waited in my car blocking one lane of traffic. After about 10 minutes a passerby pushed my car to the side of the road, at this time I noticed it was very hard to steer and the brakes started to lock up. I put the car in park and waited for the tow truck. While waiting I made several attempts to re-start the car. After about 30 minutes the car restarted and I was able to drive the 3 blocks home. The following morning I had the car towed to the dealership. I was told they couldn't find anything wrong with the vehicle. They could not recreate the issue and no error codes showed up. There were also no error coeds in the log but if the engine shut down it seems like something should be in the log. I'm extremely nervous to drive thinking this can happen again in a more dire situation (like on the freeway). I see other complaints online with this same situation and am concerned for mine and my passengers' safety.

My car is experiencing an intermittent problem with the electronic parking brake getting stuck. Sometimes when I shift out of park going into reverse or drive the activated electronic parking brake will fail to disengage like it should. When this happens I will find myself having to move the shifter back and fourth several times until it finally disengages. This occurrence will always be accompanied with an abrupt rough jerking motion coming from underneath the car.

The red parking brake light on the dash does not always come on when the parking brake is engaged. At the dealer's service department ( Sept. 2016) it came on 3 out of 9 tries when they checked it. Currently it is not working. It has been an issue since car was new, but each time I brought it in, it would work.

The car has issues with the transmission shifting erratically. There is a very loud chattering coming from the engine. It is getting progressively worse. The panoramic sunroof is constantly creaking whenever driving on uneven pavement. The car has been in the shop for check engine issues since it was three months old all related to the intake manifold and vcm. And the vehicle stalls randomly and does not set off and check engine lights. Dealerships keep saying no issue found. Rotors have warped.

I had an accident this morning in my 2015 Hyundai Sonata SE due to brake failure a vehicle stopped in front of me about one-and-A-half crawler and I applied my breaks because I saw when the vehicle stops when I apply my brakes they didn't work it went completely to the floor and had no breaks whatsoever and I slammed into the back of another vehicle at about 45 miles per hour all of the airbags deployed the steering wheel crack the front of my car is demolished I contacted Hyundai to try to find out whether they had a recall on break for the Sonatas and they said that there were no open recall on my car so I found it very strange that they said no open recall on my car but they never said that they didn't have open have any incidents with people with brake failure and I just wanted to make this publicly known that there is an issue with the brakes and I wish if there's anybody else out there that has had a similar problem they would come forward with this because I wasn't hurt very very badly but I got bumps and bruises but I could have died the same way if I was going at a high rate of speed and someone should have stopped I could have killed myself and someone else.

My 2015 Hyundai Sonata has been back and forth to the dealer. Every time I turn around the this car has a recall. I don't even know about the recall until a light pops up or I have a weird noise while driving. One time the car just felt weird while driving and I went to get it checked out and found out about the recalls. First seatbelt, then engine line needed replacing, then another part needed replacing, then another. After going there Monday for for the engine immobilizer, the brake hold light being I was told something was replaced, and oh a recall was handled. Then to come back Friday and after 4-5 hours be told the ABS has to be replaced, meaning I have to come back because it has to be ordered. Then, after leaving, now the tire pressure light is on, and there appears to be enough air in each tire!! so I don't know what is going on. Note to self, don't by a car before the year it comes out. Bought this 2015 in 2014. I really think the manufacturer needs to notify consumers of these recalls. I shouldn't find out about them only after bringing the car in for an issue or an oil change.

2015 Hyundai Sonata SE - engine vibrations/rattles/droning when in overdrive at low RPM acceleration. At times the engine has been unresponsive. Was told by Hyundai it was normal, but did not start until the car had around 600 miles - now at 7400 miles, still doing it and sounds horrid. Also, popping sound from steering/brakes when backing up and turning/using brakes at only 1200 miles. That was fixed by dealer, said I had overheated the brakes, which wasn't true, only drove on freeway and wasn't using the brakes.

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.

My concern is whether or not there is a manufacturing defect in my 2015 Hyundai Sonata limited manufactured in the United States (and potentially other models as well). My owner's manual clearly states (page 5-41) that the ABS warning light on the dash should illuminate for 3 seconds during start up as the ABS system run a self-test, then extinguish. The ABS light on my dashboard does not illuminate during startup as described in my owner's manual. Despite numerous diagnostic testing at certified Hyundai dealerships, the ABS system is functioning normally electrically and mechanically. I am making the following inquiries: 1. is the 2015 Hyundai Sonata limited designed to have the ABS warning light illuminate during startup (to confirm or deny what is published in the owner's manual)" 2. is this a manufacturing defect that requires a recall/replacement" 3. if this is not a manufacturing defect, can Hyundai motor America provide evidence (e.g., letter, updated manual publication of limited modes) that this is, in fact, normal operation of the vehicle. 4. does the vehicle have a normally operating ABS system" is the vehicle safe to drive" these concerns deal specifically with the sound operating conditions of the vehicle, which have been put into question after a routine vehicle inspection.

I purchased a 2015 Hyundai Sonata limited w/ tech pkg. I have the car with me in quebec Canada for a job. To drive the vehicle in Canada, it must undergo an inspection according to Canadian standards.during vehicle startup, the ABS warning light on the dash must illuminate for 3 seconds and then go out to signify normal operation of the ABS. My ABS light did not do this, so it failed. A diagnostic at a Canadian Hyundai dealer came back with no error codes, the ABS module functioned normally, and an emergency stop road test activated the ABS system. I'd like to say I was able to convince them by opening my owner's manual, but to my surprise the owners manual states that the ABS light should illuminate for 3 seconds and then extinguish. I immediately contacted the dealership that sold me the car and they were able to replicate the same condition (no ABS light at start up) on an identical 2015 Hyundai Sonata limited vehicle and stated there were no pending recalls. Thus, I do not think this is not a manufacturer defect (able to replicate on identical vehicle and have seen several online videos to support no ABS light on start up in limited edition Sonata), there is no malfunction in the ABS system (Canada diagnostic), and there is a discrepancy in the owners manual that is model-specific. I am unable to reference ABS lighting conditions specific to the limited edition during the inspection process. Hyundai motor America, who had no other reference than the manual, suggested another inspection. Im am reaching out to you in desperation to assist with information on this issue so I can satisfy my Canadian inspectors and the car can stay in Canada! please help!!
