Doors will not open have to pull the handle 5 or 6 times for the door to finally open the passenger door will not open at all from the outside you have to open it from the inside to let your passenger in the car. The back door on driver side will not open from the inside or the outside only the driver side front door and back passenger door will open from the outside the other 2 doors either will not open at all or only from inside. If we was just have an accident or if it was to catch fire with us inside they would have to break the windows or cut us out of the vehicle because none of the doors work properly. The driver door you have to hit unlock and jerk the handle bout 5 or 6 times then it will open finally. I've took door panels off everything is hooked up and in working order so it's gta be a malfunction within the locks or something I can't figure what else it can be.

Coils have been replaced to both number 2 and number 3 cylinders and the car does not have 20K on it yet. The symptoms were poor performance, including a feeling like the vehicle was going to stall and the inability to go much over 45 mph. Check engine light came on both times that this happened.

The car was purchased as a new car with 3 miles on the odometer from an authorized Hyundai dealership in June 2016. In August 2018, the car was driven for a little over 30,000 (highway)miles and was checked for the 30K-mile-service at the Hyundai dealership. The day after, engine check line turned on and the vehicle began shaking heavily in both high and low speed. Although I knew that the issue was related to the engine misfire, and was able to provide a obdii scan results from autozone, but the Hyundai dealership completely ignored all information I provided. In fact, they boasted about how well their "Hyundai scanners" are the only scanners that can correctly scan the vehicle. Consequently, I had to make four visits to the dealership within five days in order for them to admit their mistake and fix the problem. However, now the engine is still throttling in an unusual manner at a very subtle level. I spoke to the Hyundai's regional customer service manager about how this misfire could lead to dangerous situations on a highway where a driver's at a greater risk in higher speed traffic. But the response was simply advising me to continue visiting the dealership.

While the car was sitting in the drive, the car was turned off all of the lights except the headlights and reverse lights turned on. The only way I could turn them off is if I turned the car on and back off. It has happened 3 times in the last 3 days. The first two times it happened was about 2 hours apart from each other. The second time the lights turned off on their own within 30 minutes. The third time I was at work and am not sure how long the lights were on but I walked out of work to them on.

I have had a ton of issues. My blind spot sensors only work occasionally. (I actually know someone else with a Hyundai that is having the same problem). Additionally, sensors go off at random. I have had the warnings for flat tire pop up multiple times when there was no flat tire. One of the tones my steering wheel actually locked up and I was unable to drive. I have also had issues with my radio screen and the radio playing. My push to start button also has issues. Sometimes it will not turn the whole car off. They replaced something in the bottom but it is still happening. Today it actually had a hard time starting. This has been happening since I got the car. I've had it less than a year and it has been to the shop a couple dozen times. This happens at all times both when I'm moving and not moving depending on the issues. It has also happened when I was driving slower and faster. My screen has also frozen and I have been unable to use it. Both in motion and parked. P
