2020 Jeep Renegade

Was driving and entering onto a freeway going about 40-50mph. I was able to reach 60 mph on freeway. All of a sudden the thing where car shuts off when stopped at light that came on and then check engine light and then had to slow down however after slowing I was not able to go above 40 mph and had to try to get over to pullover. I let my car sit for a couple hours and when I put it in drive and accelerated my front end was smoking and extremely hot. When I was able to open hood everything was hot opened oil cap as I had a puddle of oil now under my car smoke came pouring out of where you put oil. Not sure if connected but the month prior my car was being fixed for a blower motor and at that time was leaking oil. I had an issue previously on a Chevy Malibu where blower vacuum motor broke and caused broke piece to go into engine fan which then needed engine replacement. It is currently being diagnosed however all they can tell me is that I need a new engine likely and they can’t get enough compression to diagnose cause. This is dangerous with the amount of oil lost in that short amount of time. It should be noted it was just in for an oil change 2 wks prior to the incident at the jeep dealership where I bought the vehicle.

I WAS PARK AT A PUBLIC PARKING SPOT(POST OFFICE) WAITING FOR MY FRIEND, THE ENGINE WAS RUNNING. WHEN MY FRIEND GOT TO MY CAR, I PRESS THE BRAKE TO PUT THE CAR IN REVERSED. IT REVERSED ABOUT 3 FEET AND SUDDENLY STOP. I WENT AND PUT MY FOOT ON THE BRAKE AND SWITCH IT TO DRIVE AND IT WONT GO FORWARD EITHER . MY FRIEND GOT OUT AND CHECK FRONT AND BACK TO SEE IF SOMETHING WAS BLOCKING THE TIRES FROM MOVING FORWARD OR REVERSE. THERE WAS NOTHING. I DECIDED TO PUT THE CAR IN PARK AGAIN. THE EBRAKE BUTTON LIGHTS WAS NOT ON NOR ANY INDICATOR IN THE DASHBOARD. BUT ONCE I PRESSED THE BUTTON. IT RELEASED THE CAR AND WAS ABLE TO MOVED AGAIN. ALSO MY CAR SHOWED A WARNING SIGN TWICE IN THE DASHBOARD SAYING "PARKING BRAKES NEED SERVICE" BUT I TRIED TO CONTACT MY DEALER 2 CONSECUTIVE DAYS AND WONT ANSWER OR RETURN MY CALL BACK. AND MY CAR WHISTLES STARTING AT 40MPH HIGHWAY OR CITY STREET.
