2023 Chevrolet Malibu

This vehicle has been taken to Days Chevrolet on two different occasions no check engine lights will come on but as you drive it surges and almost cuts off at times I have taken it in for this problem may 1 2023 and June 19 2023 every time they tell me the car is running as it should it also has a popping and rattle in right rear and they say they can't duplicate the problem. This car is going to kill someone

I was driving the car from home to work during morning rush hour in downtown Chicago. I was stopped at a red light and the auto-stop feature engaged as it is intended to do. When the light turned green I put my foot on the gas to go but the car wouldn't move. Cars behind me started honking & going around me. I tried various things but couldn't get the car to move although the ignition light was green. I finally put my emergency flashers on, shifted the car to park, pressed the ignition button to turn the car to off position, then depressed the brake pedal and the ignition button to turn the car on again, then shifted to drive and the car then moved forward as normal. No warning lamps have ever appeared re this. I immediately contacted my dealer to report this problem & soon after took the car there, where they confirmed this malfunction & communicated with GM Tech Line to try to resolve the problem while I sat at dealer all day but at end of day there was no resolution & they had no loaner car to give me & I needed the car so I left with it but thereafter always drove it only w/auto-stop feature turned off as I feared if it happened again I could be rear-ended. Dealer has now had my car for a week trying to ascertain how to fix this but because they say this feature is now not acting up they don't know how to fix it & they say GM Tech Line isn't giving them advice on how to resolve it. I cannot leave my car w/dealer indefinitely so now am forced to drive the car in this condition & need to always try to remember to turn off the auto-stop feature (or risk driving it in unsafe condition), which is not the right solution for a brand new car that had less than 2,000 miles on it when this started. Available for inspection upon request.
