2019 CHEVROLET IMPALA Fuelpropulsion System Problems

Jerking while picking up speed, key fob keep saying not detected, Radio feature work but stuck to basic screen I guess electrical problem Brakes is very rough not sure

CHECK ENGINE LIGHT RECENTLY CAME ON, CAR COMPLETELY LOST POWER AND TURNED OFF DURING AS I TURNED RIGHT AT A LIGHT, HAD ONSTAR RUN DIAGNOSTICS, CODE INVOLVED THE EMISSIONS SYSTEM, WAS ADVISED TO FILL UP WITH HIGH QUALITY FUEL, AND DRIVE WITH THE GAS CAP OFF TO CORRECT IT. I WAS TRAVELING ON A FAMILIAR HIGHWAY AT NIGHT, CRUISE CONTROL SET AT 60 MPH, FURTHER DOWN THE HIGHWAY I SEE DEER RUNNING ACROSS THE HIGHWAY, THEY ARE COMMON IN THIS AREA, I TAPPED MY BRAKES TO SLOW DOWN FOR THEM TO CROSS AND IMMEDIATELY THE CHECK ENGINE, ANTILOCK BRAKES, POWER STEERING, STABILITY TRACK AND BATTERY SAVER INDICATORS ILLUMINATED ON THE DASH AND THE CAR WOULDN'T BRAKE AS IT SHOULD RESULTING IN AN ACCIDENT THAT I HAD MORE THAN ENOUGH TIME TO PREVENT AND COULD HAVE EASILY AVOIDED IF THE BRAKES WOULD HAVE PERFORMED NORMALLY. MAINTAINING MY VEHICLE AND KEEPING UP...
