Air bags

2 reports
“A WARNING LIGHT FOR THE PASSENGER SIDE FRONT AIRBAG IS ON. BMW WANTS TO CHARGE ME $1500 TO REPLACE THE FAULTY AIRBAG. HOW CAN IT BE DAMAGED IF IT'S NEVER BEEN USED? HOW IS THIS REPAIR MY RESPONSIBILITY? ADDITIONALLY, THIS BMW BURNS OIL. IT SEEMS TO BE A PROBLEM WITH ALL 8 CYLINDER MODELS AS THEY AGE. I HAVE TO ADD A QUART OF OIL EVERY 300 MILES OR SO AND THE CAR BLOWS BLACK SMOKE VIA THE EXHAUST. I'VE SPENT $1300 TO REPAIR IT, BUT IT DIDN'T REPAIR THE ISSUE. NOW I'M BEING TOLD IT'S A $10,000 REPAIR. HOW IS A PROBLEM THAT'S SYSTEMATIC WITH SO MANY 8 CYLINDER BMWS MY RESPONSIBILITY?”
