2026 Cadillac Escalade ESV Engine Problems

I had been traveling on the freeway for about 3 hours when I decided to exit for a quick stop. While on the exit ramp, I was stopped about six cars back from the traffic light. When the cars inched forward I went to do the same and noticed there was no movement when I took my foot off the break. I pushed on the gas a little bit more than I normally would have to, and the car eventually jerked forward causing me to have to slam on the brakes. I turned off the auto start-stop feature at this point. The other cars inched forward again a moment later and again my car did not move when I took my foot off the brake. This time I really had to press down on the gas quite a bit and the car jerked forward again causing me to have to slam on the brake to avoid the car in front of me. The light turned green shortly thereafter and all the cars went, but I could not accelerate because the engine completely died. The car still had power so I turned it off and attempted to restart. All I heard was squeaking from the engine and nothing else happened. I waited about 15 minutes and tried it again, but the same thing happened again where the engine wouldn't turn over but there was some squeaking noises. The vehicle was towed to a nearby Buick dealership and when scanned in the service department I was told the issue is with the crankshaft. I've not been provided any details since. There were no warning signs or lights prior to this happening. I was almost rear-ended during this.
