Car Accelerates On Its Own problems of the 2019 Hyundai Tucson

September 2019, four months after we purchased it brand new. The vehicles stopped responding to my acceleration on highway speeds when all the technology screens went out in the vehicle. While at a red light the vehicles rpm's will visually go up and down and the vehicle shutters as if it is going to turn off. It has unintended acceleration when I'm sitting at a standstill and go to accelerate the vehicle will jump so to speak once the accelerator is engaged. Unfortunately my videos are too long to upload but I do have confirmation of 2 of the 3 concerns but am unable to record the highway concerns due to obvious safety reasons.

2019 Hyundai a Tucson was stopped in driveway with auto hold on while speaking with an independent witness. Feet were not touching any pedals and auto hold was engaged with verification on dash. Vehicle suddenly accelerated down driveway and into street traveling towards mailbox across street. Was able to apply brakes with a lot of pressure and stopped vehicle. Vehicles rpm's and speed went up like pressing hard on gas pedal. Vehicle has 1800 miles.
