2018 CHEVROLET IMPALA Service Brakes Problems

Check engine light did not come on when battery was bad.also brakes feel spongy and go to the floor at times,pads and rotors are good.

GETTING A SECOND LOOK AT AIR CONDITIONING. I WAS TOLD THE COMPRESSOR COULD BE LEAKING AS THERE HAS BEEN NO FREON FOR OVER A MONTH OR TWO. THE FREON IS 120/POUND AND COULD COST 1000, HE MENTIONED FOR FREON ALONE. THIS IS A 2018, PURCHASED LAST YEAR AND I'M DEALING WITH A COMPRESSOR ISSUE AS WELL AS VERY EXPENSIVE FREON?

THE CAR WAS STOPPED ON A PARKING LOT EXIT RAMP. WHEN THE CAR AHEAD OF ME MOVED FORWARD I TOOK MY FOOT OF OF THE BRAKE SO I COULD MOVE FORWARD. WHEN I APPLIED THE BREAK TO STOP, THE BREAKS DID NOT WORK AND I HIT THE CAR IN FRONT OF ME.

OCTOBER 10TH, I WAS IN AN ACCIDENT WHERE I WAS LITERALLY AN ENTIRE CAR LENGTH BACK DRIVING WITH THE FLOW OF TRAFFIC AT 50-55 MPH, WHEN THE VEHICLE IN FRONT OF ME CAME TO AN ABRUPT STOP ON THE FREEWAY. I SLAMMED ON MY BRAKES BUT MY CAR SLID STRAIGHT INTO THE BACK OF THE VEHICLE IN FRONT OF ME. IT FELT AS IF MY BRAKES WERE NOT STOPPING MY CAR. I NOTICED THIS HAPPENING BEFORE ON A MAIN STREET AND I WAS TRAVELLING AT 45 MPH BUT I DID NOT THINK ANYTHING OF IT AT THE TIME.

TIRES-TIRES KEEP LOSING AIR PRESSURE, THEY APPEARED NEW BUT WHEN TESTED PROBLEMS WAS FOUND, THEY WERE WORE TO THE OUTSIDE AS IF ALIMENT WAS NEEDED, NEW TIRES WAS PURCHASED ELECTRICAL/BATTERY-THERE IS A FREQUENT SHUT DOWN OF ELECTRICAL SYSTEM, WHILE DRIVING THE ENGINE LIGHT COME ON, FROM THE DRIVER INFORMATION CENTER (DIC) THE WAS 14.7, THE BATTERY WAS CHECKED TWICE WITHIN A PERIOD OF TWO DAYS FROM THE DEALERSHIP, THE FIRST DAY THE BATTERY WAS GOOD THEN ON THE SECOND DAY THEY SAID I HAD A BATTERY PROBLEMS, PURCHASED NEW BATTERY, NO WARNING TRIED TO CRANK BARELY TURNOVER, SOMETIMES THE DIC GOES BLANK AND IT TAKES A WHILE FOR IT TO DISPLAY AGAIN, THIS HAVE HAPPEN AT LEAST 3 TIMES BRAKES-WHEN BACKING UP THERE IS A FREQUENT LOUD MEDAL TO METAL SOUND, THIS HAVE HAPPENED AT LEAST 4 TIMES

IN FEBRUARY 2019 I PURCHASED A 2018 CHEVY IMPALA PREMIER, UPON DRIVING THE CAR I NOTICED THAT THE BRAKES WERE NOT WORKING LIKE MY 2018 CHEVY CAMARO BUT I CHUCKED IT UP TO THE CAR BEING HEAVIER AND PAID IT NO ATTENTION. FOR MONTHS I HAVE BEEN THINKING THAT MAYBE I JUST NEED TO GET USED TO THE BRAKES ON MY NEW CAR AND THAT IT WAS NOTHING. WHILE I DRIVE AT NORMAL SPEEDS (40 - 45 MPH) MY CAR SLID AN EXTRA 5- 10 FT MORE THEN IT IS SUPPOSED TO EVERY TIME. YESTERDAY WHILE BRAKING MY BRAKES JUST TOTALLY DID NOT RESPOND CAUSING ME TO HIT THE BACK OF ANOTHER DRIVER. I WAS DRIVING ABOUT 30 MPH LITERALLY JUST TURNING OUT OF A SHOPPING PLAZA WHEN THE ACCIDENT HAPPENED. I STARTED TO PRESS THE BRAKES ABOUT 50 METERS AHEAD AND MY CAR DID NOT BUDGE NOR DID IT...

I WAS DRIVING AND LADY CAME TO A COMPLETE STOP AT RAIL ROAD TRACK AND I COULDN'T STOP I RAN INTO THE BACK OF HER
