2019 BMW 540I Unknown Or Other Problems

Radiator Grill does not open when running. It remains in the close position. It started with the engine symbol that appeared on the dash.

I PURCHASED FOUR (4) MICHELIN PILOT ALPIN PA4 TIRES IN 245/35/20 FOR THE FRONT AND 275/30/20 FOR THE REAR. I SUBSEQUENTLY HIT A POTHOLE AND HAD THE FRONT DRIVER'S SIDE TIRE BLOW OUT. I THEN HAD THE TIRE REPLACED. A COUPLE MONTHS LATER, I HIT A POTHOLE ON THE HIGHWAY WITH THE FRONT DRIVERS SIDE TIRE, WHICH AGAIN CAUSED THE TIRE TO BLOW, BUT THIS TIME DAMAGED THE WHEEL BEYOND REPAIR.

THE DATE BELOW IS THE MOST RECENT DATE TAKEN TO THE BMW DEALER IN BALA CYNWYD, PA 19004 - BMW OF THE MAIN LINE.
