NHTSA Complaint #11577420 — 2021 CHEVROLET BLAZER

I was driving on the highway when my car started operating like it was in neutral. RPMs was high but the car started to stall and slow down and because of it I had to immediately pull over. The car would not go into gear. I attempted to put it in drive ajd press the acceleration pedal but it just revved. Same with putting it in reverse. It's a safety concern because my car could not maintain highway speed and abruptly went stagnant. I had the vehicle towed to dealer and they replaced the entire transmission system. The car always had a shudder feel to it when accelerating from 0 onwards to 40 mph.The day this occurred there was no blatant warning signs.
