general problems of the 2018 GMC Sierra 1500 - part 2

My 2018 GMC sierra slt's break pedal becomes extremely difficult to press, and I can hear something that sounds like air coming from the pedal. This happens especially at lower speeds. This caused me to crash into a concrete wall and damage my truck. My truck has only 10,000 miles.

Driving slowly in bumper to bumper traffic. I was stopped with my foot on the brakes, and the truck started moving forward. I thought engine surge, but it was not. I pumped brakes hard and the truck stopped. This has happened 2 times.

Tl the contact owns a 2018 GMC Sierra 1500. When the contact shifted into drive, the vehicle lunged forward with the brake pedal depressed. As a result, the vehicle crashed into a handicap sign. There were no injuries. Prior to the crash, the vehicle was taken to bill kay Chevrolet (located at 601 ogden Ave, lisle, IL 60532, (630) 968-2900) to be diagnosed due to hard shifting. The contact was informed that a transmission re-learn of the software was needed to correct the hard shifting; however, the failure became more pronounced. The contact stated that the failure was intermittent. The vehicle was not repaired. The manufacturer was informed of the failure. The approximate failure mileage was 13,000.

I was in the bank atm drive through and the guy ahead of me started to go, I barely pushed the gas pedal and he decided to stop. I hit my brakes and the truck was hard to stop, almost like the gas pedal response was still in the go mode before it had the chance to react to my input of taking my foot off the gas to apply the brakes. I can duplicate this behavior all the time.

When driving vehicle at any speed it steers to the left or right . Not a simple alignment pull or wander I can feel the wheel as to which way it wants to steer at random. If not paying attention or if you were to let go of the steering wheel it will go off the road absolutly not safe to drive. While accelerating the vehicle feels like the brakes are being applied and does not accelerate I have to give excessive gas petal throttle to get up to speed. There have been times I have came home from as short drive and I can smell the brakes they smell burnt hot. One instance I was merging onto the highway and the truck struggled to get up to 60mph I had the petal floored and the truck would not go over 65mph the engine was @ 5000rpm maxed out it would not shift nor go faster than 65mph. Randomly transmission thunks thud and slams into gears when the automatic transmission is shifting at low speed below 50. While driving truck feels like the drive tran is bound up like brake is applied on individual wheel(s) . I have had nothing but problems with this truck very weird issues that don't make mechanical sense. Also the instrument cluster gauges and infotainment screen don't light up just black screens after starting vehicle. Happened 2 times now. Radio was off while driving then came on full volume without touching anything. Service stability /steering warning came on once. I can hear front transfer case engage and disengage at low speeds randomly when in 2wd. Randomly stuck in low gear when accelerating from a stop. And you don't have to use the brakes much to stop you because as soon as you let off gas petal the vehicle nearly comes to a stop without applying brakes. And if you are turning it will at times come to a complete stop. Has been to dealer 6 times now they say everything checks out. There is a major computer issue or is hacked per all ive researched.

My vehicle is hacked anytime I am driving the vehicle I am not in full control. The vehicle steers itself left or right while driving, the brakes are always on while driving sometimes braking harder but always on. The infotainment system has many glitches. This vehicle has been back to the dealership more than 15 times has been out of service over 35 days gm even flew a engineer/tech to inspect the vehicle and says they couldnt find anything. Therefore this vehicle is hacked there are so many issues and glitches and the fact that the truck only acts like this when I am driving no one else. Like it can be turned on and off instantly. I have tons of videos pictures and supporting documents backing this. I need help this is a serious issue and there is so much more to it than I can type here someone please get ahold of me to help or point me in the right direction. This vehicle will be returned to gm soon as they are doing a vehicle replacment per all the issues but this needs further attention because if this can happen to me it can happen to anyone . Please help.
