Owners/service Manual problems of the 2020 Hyundai Santa Fe

Brake has been sticking last couple of weeks so that I had to pump brake to release to start. This morning I went out to the driveway and could not get into car with either remote or by using blue link on my phone. I used the manual key but could not release any other doors or lift gate. No lights, hazards, radio no nothing. I have had a few dead batteries and never had a car that dead overnight. I drove home from work previous night and I was outside after dark next to my car, no lights left on. I called roadside assistance, first guy said he thought there was a short, parking brake would not release and car still did not start. A different tow truck had to come with dollies and it was towed to the dealer. Dealer said it was a dead battery at 4918 miles! thankfully I was at home and the heat index was not at 105 degrees yet for the day.

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.

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.
