Date: Friday, 3 July 2020. My car would not unlock with the key fob. Thought the key fob was dead and grabbed the spare to try again. No luck with that one either. Tried using the blue link app to unlock. Unsuccessful again. Unlocked my car with the key from the fob and got in. None of the interior lights came on (I keep this feature on). That should have been my first clue. Tried starting the vehicle like the owner's manual suggests if the key fob battery is weak. Didn't work. I tried to test different functions that would normally work if a vehicle is off (I.e. the lock/unlock buttons and hazard lights). Nothing worked. I had to call for a tow to my dealership, which has to wait until after the holiday weekend (4th of July). I will not find out the problem until after. I did not leave any lights on or any doors open. I just used my car the day before this and there was no indication of anything wrong with the vehicle. No lights on the dash came on to alert me of anything and my car is acting dead. More dead than your regular needing a jump start dead. The only thing I have not tried is jump starting in fear of invalidating the warranty in some way. Thankful my car is just in my driveway and I'm not stranded with my kid somewhere.

My car is siting in park, running with the driver's door open in my town house parking lot. I get out of my car to open the passenger's back door as well as my trunk for her. I then get back into the driver's seat. I am waiting on my friend to load her items into my new Santa Fe for an out of town retreat. She finishes loading items and proceeds to get into the passenger side front seat. As she is getting into the car, "she says she needs to go to the bathroom". I tell her let's go now before we get started on our trip. We were suppose to be meeting about 10 college students. So I get out of my car since I have the house keys. My car is still in park and running. I do leave my driver's door open about a 20-25 degree angle. My friend walks around the back of the car. As we are walking toward my townhouse, I turn around because I hear a noise. I immediately see my car not rolling but backing up on a small incline upward across my parking lot. It seems to have picked up speed and then hits the back of a parked car in the parking lot. My car hits the parked gray Camry with so much momentum that it butterflies my driver's door completely open and the car never slows down. The car continues moving while the inside of my driver's door scrubs the parked Camry. After my car moves past the Camry it is still moving at an accelerated rate. I am yelling and running to my car with my keyfob trying to push buttons to get it to stop. My friend is running and chasing my car. She is able to get to my car and jump in where she pushes on the brakes very hard to make the car stop. If she had not been able to do that my car would have hit a parked black truck or would have jumped the sidewalk and ran into a townhouse before it stopped. Once my friend got the car to stop. She looked down and it was still in park and was not making the dinging noise it usually does when it is in reverse.

The fca (forward collision avoidance) system does no work as it should. It does not see vehicles or pedestrians directly in front while not in cruise control. The only time the system alarms is when following a vehicle, which is in the same lane on city streets, and then the target vehicle turns right and creates no hazard. The fca does not work according to what is mentioned in the owners manual, nor does it operate like it is shown in a youtube video sponsored by Hyundai.
