The contact owns a 2021 Chevrolet Blazer. The contact stated that oil was leaking from the vehicle. There were no warning lights illuminated. The vehicle was taken to the local dealer, where it was diagnosed that the cam shaft carrier needed to be replaced. The vehicle was repaired, but the failure recurred. The vehicle was taken to an independent mechanic, who determined that there was a separation in the transmission, oil cooler line, valve, and hoses that needed to be replaced. The vehicle was not repaired. The manufacturer was contacted and submitted a complaint. The failure mileage was approximately 63,000.

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.
