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!!

At 1540 miles 2015 Hyundai Sonata limited engine cam advance sensor failed. This caused engine running rough and limited power with inability to climb hills without constantly downshifting. Highway driving is dangerous due to inability to accelerate and merge and loss of power on hills. Other owners are unable to start their cars altogether. Engine monitor warned of problem and recommended full systems diagnostic which pointed to cam sensor issue. Supply of sensors was backlogged due to multiple failures nationally. This is also evidenced by the number of online owner complaints for the same issue many stating long delays in obtaining the part and multiple part failures. In my case, after 200 miles with the new sensor if failed a second time and I am again waiting for parts. The vehicle now has 1700 miles on it since new. For a new vehicle this is a totally unacceptable level of quality. While I was told the O-ring seal fails causing oil to saturate the sensor I personally believe they do not know the full reason for the failures, I.e. poor sensor manufacturing, materials issue, O-ring issue etc. In speaking with Hyundai corporate personnel it became obvious to me that they are trying to avoid a national recall by understating the scope of this problem nationally and trying to minimalize the extent of the problem in our conversations. I suggest an investigation to determine the extent of the issue and see if it warrants a recall. For other owners or potential buyers, while this failure has been my primary complaint I have noted other issues with the electronic warning sensor inconsistency and cabin electronics systems which have not been resolved. This my first experience with owning a Hyundai and I am terribly disappointed. Next step is lemon law filing.

Brand new car purchased and few issues. 1. gas gauge only goes up to 7/8 even with full tank fill up. 2. gas mileage does not seem to indicate correct mileage. With full tank gas, the indicator shows 450+ miles, but actual mileage is 300~350 miles. 3. error occurs when playing songs from iphone 6 using usb cable.
