I was driving at 6:20 am on the New Jersey turnpike. I was in the left lane and going approximately 70 mph using the scc (smart cruise control). All of the sudden, the lights start flashing and the car completely turns off. Since it was before sunrise, everything was black and I couldn't even see where I was driving, not to mention that the steering wheel became locked. 10 seconds later, the care came back to "life". it did that same intro with the "system check" thing as it does when the car is started from a park position- only I was on the highway going 70 mph. I have never heard of something so absurd, but I guarantee that if this was during rush hour or a busier time during the day- there would have been a major accident!

- Highland Park, NJ, USA

Put blinker on for right hand turn, made the turn, when the blinder stalk (which also contains headlight controls) returned to home position, the headlights went out, and the instrument panel indicated my lights had switched off. My light knob remained in auto, with the computer thought I turned them off. This was at night. I could not see when my lights turned off. It is very unsafe to be in motion and have your lights cut out!!! this problem happens frequently now, getting worse. It's obviously a bad connection within the blinker stalk, causing the light mode to change on its own when turning.

The safety system on my car more often then not warns of danger that does not exist, especially in direct sunlight at dawn and dusk. The cameras falsely warn of impending crashes or alerting you that you have swerved out of your lane even when you're dead center in your lane with no other cars around. Hyundai has no solution to the problem.

While stationary I noticed the car's engine sounded like it was ticking. I drove off about 35 miles per hour when my 2015 Hyundai Sonata limited stalled while driving. The car started shaking while attempting to speed up to keep the vehicle running. I had my passenger who witnessed the incident and we recorded using the cell phone to record the incident. The engine light came on then off again. Eventually it cut off completely. I had to restart and the speed of the vehicle would not go past 50 mph. The engine shook the entire car and sounded like the gears did not want to shift. The dealer was not able to replicate the issue or find any codes on their system. This same thing happen to my 2011 Sonata in which Hyundai refuse to pay in a class action lawsuit because I traded out of the vehicle a year after they replaced the engine. The engine also stalled while traveling at highway speed and started smelling like an electrical fire while smoke came from under the engine. I had to have it towed back to the dealership.

On three different occasions the dash flashed "check TPMS" meaning check air in the tires. On all 3 occasions the car would not go into gear.the next occasion the check TPMS came on so I put air in the tires and drove around the corner to reset the tire pressure monitor (computer). Upon coming around the corner to park the car the check TPMS warning came on again the car powered down and I coasted to park. The next morning I called the dealership to have the car checked I was told from jared that the technician did a software update and that " he thinks, maybe, might have fixed the problem. At this point I did not pick up the car because they could not guarantee the car had been fixed and that it will not die while driving around Hyundai service department said they were not sure because they could not duplicate the problem I had with the car. I left the car there contacted hyndai corporate where they opened a case #9327831.. they in turn had a fast team working on my car and they are not sure if the car is fixed or not because they could not duplicate the same problem. The have had my car for a month now still have not been able to find out what the problem is. I was told it does not fall under lemon law unless the car does the same thing again. But I do not know if the car is fixed 100% it only has 12,513 miles on it. Car would not go into drive the gear shift would not move to where I could drive the car.

I purchased a used 2015 Hyundai Sonata with 43K miles. I have had it for three months with minor problems such as sluggish acceleration, hard deceleration when removing foot from gas pedal, and a noisy engine. However, on 4-8-2016 at about 7:30 am, I was attempting a left turn on a busy metropolitan street when the 2015 Hyundai Sonata shut down suddenly, completely turned off! all the warning lights on the dash lit up like a christmas tree and then went dead. The 2015 Sonata came to a stop, and there was a truck approaching at a high speed rate that had to swerve around me to prevent a collision with me. I was lucky the driver was paying attention. This problem is very dangerous and it is just a matter of time before someone is killed due to this problem, which seems to be occurring in many 2015 Hyundai Sonata vehicles. I believe Hyundai must know about this and Hyundai probably knows what is causing this safety issue with the 2015 Sonata. Hyundai or NHTSA need to recall the 2015 Hyundai Sonata vehicles asap!! if nothing else tell the owners what the problem is so that they can repair it on their own dime!

I bought a 2015 Hyundai Sonata eco on Aug 30, 2015 and shortly after purchase low tire pressure light and display came on while driving 65 mph indicating that the rear drive wheel was at 9psi. I pulled over on the side of the road and inspected tire and the tire had a normal feel. Drove for 10 mins and tire pressure went back up to 35 psi. On 11/15 the battery and oil light came on while the vehicle was in drive and immediately following the lights the engine shut off. I sat in the middle of the road and had to restart my vehicle and then drove it to the dealership. The dealership says, "2691 performed all system fault code search and tsb search. No fault codes stored at this time and no related tsbs for customer concern as described." The dealership later found a warning saying to reprogram the sensor and reprogrammed the sensor as the "fix". I opened a case with Hyundai and the results of the case was to obtain a print out of the error codes (which is showing none) and to file a complaint with the BBB if I wasn't satisfied with the outcome. I am concerned that my vehicle is not properly recording issues that my vehicle encounters like my engine shutting off. The mechanics at the dealership said that error codes are thrown usually when the sensors go bad. I am concerned for my safety in a vehicle that Hyundai will not fix solely because there are no error codes on file. I believe that the error codes that should be in this report to show the engine shutting off are not being recorded properly. Hyundai will not do anything to investigate my issue unless they see a code so until a code is thrown and recorded properly I am left with a vehicle that is unsafe and is not performing correctly.

This Hyundai sonota has a push button ignition. Once the engine is started, a person can leave the vehicle with the key fob in their pocket and the engine stays running and will not shut off. This is in violation of Federal Motor Vehicle Safety Standard 114. Once the key is removed from the vehicle the engine should shut off. This engine is so quiet you cannot even hear it running while in the vehicle and if someone is partially color blind you can barely see the red and green indicator. This engine will run in an idle state no matter where the key causing risk of fire, carbon monoxide poisining and death and injury to anyone near this vehicle if left running and since the car stays running once it is started anyone can walk away with the key fob in their pocket and the car stays running no matter what. There are no reminders when exiting the vehicle that the engine is running, there is no automatic shut off in the vehicle, there are no reminders in the vehicle that the engine is running. The push button starts are not only a safety threat but also can be hazard in a parking garage if the engine catches fire due to over heating it can affect all the other vehicles in a parking garage and cause even worse damage.

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!!
