NHTSA Complaint #11433260 — 2019 NISSAN SENTRA

While driving at night, going to the movies, it was a windy night, some obstruction, something small, nicked the front plastic bumper. there was no warning from the AEB. After that happen, the alert AEB light popped up and it's still on. Nothing was broken on the veh. As a matter of fact, there is no damage or nothing to the veh. Just that nick. Bought the car brand new with about 20 miles on it. This happen about two months after. Took it to the dealer where I bought it and told me they don't cover it. It would cost me $1200 dollars out of my pocket to fix it. Also, there was no other vehicles involved for that matter. So, what is the use of buying the extended warranty if when the time comes to use it, it's not covered?
