The rocker switch allows driver to increase or decrease speed when the cruise control is activated. The rocker switch permits speed increase in increments of 1 mph or 5 mph. If pressed up until a resistance point, the speed increases by 1 mph; if pressed beyond the resistance point, it increases by 5 mph. In my instance, I was on cruise control at 61 mph (in a 55 zone, where traffic was also moving in the 60's). I wanted to increase speed by 3-4 mph using the rocker switch to safely complete an overtake. However, the rocker switch got stuck and caused the car's peed to increase past 80mph. I almost missed hitting the car ahead of me.
ACCELERATION ISSUES. I COMPLAINED TO BMW ABOUT THE ISSUE NOVEMBER 2018 FOR MY 2018 BMW. HOWEVER, BMW SAID THERE WASN'T A PROBLEM. ON SUNDAY AT AROUND 6:28 PM I WAS PULLING INTO A PARKING SPACE AT MY CHASE BANK AND THE CAR SUDDENLY STARTS ACCELERATING CAUSING ME TO HAVE A HEAD ON COLLISION WITH A PARKED CAR. MY 2015 BMW HAD THE SAME PROBLEM. I WAS IN RALPH'S PARKING LOT IN BEVERLY HILLS ABOUT TO PULL OUT WHEN SUDDENLY MY BMW ACCELERATED, AND I NEARLY KILLED TWO PEOPLE. WHEN I BOUGHT IT IN FOR SERVICE BMW REPAIRED THE PROBLEM. SOMETHING WAS CALIBRATED TO HIGH.
WAS ON A ROAD TRIP, DROVE 600 MILES PREVIOUS DAY. NEXT DAY EVENING, PIRELLI RUN FLAT TIRE BLOWS OUT ON A FREEWAY. I HAD JUST PASSED THE TOLL PLAZA AND WAS ACCELERATING TO MERGE WITH THE TRAFFIC. RUN FLAT REINFORCED SIDEWALLS SHOULD'VE ALLOWED THE TIRES TO BE USABLE EVEN AT 0 PSI BUT I EXPERIENCED SEVERE VIBRATION COMING THROUGH THE CHASSIS, CAR PULLING TO THE LEFT AND EMITTING A TERRIBLE GRINDING NOISE THAT FELT TERRIBLE AND UNSAFE TO DRIVE. DESPITE APPEARING FINE AT FIRST GLANCE, THE TIRE WAS ACTUALLY SEVERELY DAMAGED. THE INNER SIDEWALL HAD A LARGE GASH. THE CAR WAS FINALLY TOWED TO A BMW SERVICE STATION AND THE ONLY OPTION WAS TO REPLACE THE TIRE. IN THE MEANTIME, THE BMW IDRIVE INFOTAINMENT DISPLAY SAID I COULD SAFELY DRIVE 50 MPH FOR 50 MILES.
