general problems of the 2018 Hyundai Tucson - part 2

I purchased my 2018 Hyundai Tucson limited 1. 6l forward drive new in November 2018. I started experiencing problems a few weeks after my purchase. The vehicle is slow to accelerate at times and other times the vehicle lurches/accelerates forward at a high rate of speed with my foot on the brake pedal. For instance, I was at a drive thru with my foot on the brake pedal and my Tucson began to accelerate forward. I was so afraid that I was going to hit the car in front of me that I turned the vehicle off. On numerous occasions it has lurched/accelerated forward with my foot on the brake pedal. Other times when I begin to accelerate after stopping at a stop light the vehicle just hesitates to move at all. It is very slow to accelerate for a turbo vehicle. Concerning my brakes, my brakes are making a high pitch squealing sound. I have taken my Tucson in for service for the brake issue, and I have been told that there is nothing wrong and that is the noise that Tucson brakes make. Brakes do not make a high pitch squealing noise for no reason at all. Also, I took my Tucson to be serviced for the engine/transmission problem and I was told that there was nothing that they could do about the problem. This SUV is a deathtrap. The 2018 Tucson 1. 6l needs to be recalled and the engine replaced with a 2. 4l engine and the brake system needs to be redesigned.

Once my brand new Tucson hit 500 miles on it, it suddenly unintentionally accelerates while my foot is already pressing firmly on the break pedal. The first time, it happened as I was approaching the peak of a hill. I was going 25 mph. My foot was already pressing on the breaks, anticipating the decline, when my car jolted forward and took off. My foot slammed on the breaks even harder, however I watched my speedometer hit 40 mph while simaltaneously, my rpm decreased to 1. . . (yes, down a hill. ) for about 5-7 seconds the rpm and seppdometer would not increase or decrease once hitting 40 mph and 1 rpm. I had to lean over the wheel and slam my breaks to the floor before I regained control of the vehicle. Once this occurred, the car lagged, struggling to accelerate throughout the remainder of the drive (all flat roads). It is now day 5 of experiencing this, and it now occurs multiple times every time the vehicle is in motion, whether breaks are being applied prior, or not, regardless of the type of road I am on (flat, hill etc. ) I was exiting a parking garage that had a mediocre ramp to exit the garage. My vehicle was going 12 mph when I turned right to proceed down the ramp. My foot slowly pressed the break pedal, and my vehicle accelerated to 28 mph, and maintained that speed for 3 seconds, before responding to my breaks. Yes, my foot had the breaks pressed all the way down. Another example, yesterday I was on a flat road driving at 27 mph when it suddenly accelerated to 45 mph, and the rpm dropping suddenly from 2, to 1. After a few seconds of my foot slammed on the breaks I regained control and pulled the car over. I turned the engine off and waited about 5 minutes. When I turned it back on, and began driving (3 minutes left in my drive), the car continued to lag, lunge forward, and could not reach speeds higher than 30 mph. This car is brand new.
