2024 Cadillac XT6 problems

“am experiencing multiple issues with my 2024 Cadillac XT6 that affect drivability and potentially safety: 1.Intermittent Transmission Shift Jerk •The vehicle occasionally exhibits a sudden “jerk” or abrupt shift while accelerating, mostly in 2nd–3rd or 3rd–4th gear. •The issue is intermittent and cannot be consistently reproduced during dealer visits. •The dealer has performed two transmission fluid flushes within one month, but the problem continues. •No diagnostic trouble codes are stored, making it difficult for the dealer to duplicate, but the jerks are noticeable and concerning while driving. 2.Startup and Engine/Transmission Noise •Upon starting the vehicle, I hear unusual noises described as [whining •Noise is also sometimes heard during idle or even briefly after the vehicle is turned off. •These noises occur intermittently, sometimes during cold start or light driving, and may indicate an underlying transmission, engine, or accessory issue.”

He can’t get the codes because whatever is going on with car it’s not talking to the computer. I’ve been on a major highway and the car just shuts down. I’ve asked Cadillac to repurchase the car because I am afraid of being in a major accident and killed because I never know when the car will shut down. Cadillac told, me to keep driving the car until it showed up again and they would not repurchase it. If I get rear ended on a 4 line highway by a semi truck because the car just…”
