I’ve had the car for less than a week…

Leased a 2026 CLA last Friday. I was driving on the freeway tonight, hit a pothole and tire immediately goes flat. I’m watching the tire psi drop like a NYE countdown- super freaked out. Was able to get off the freeway and to the side of the road thank goodness.

I thought Mercedes had run flats?

Is this common bc the car is low? I’m hoping this was a freak occurrence. Theres always road construction around here. I have roadside assistance, currently getting towed to a tire shop. :/
