NHTSA Complaint #11552110 — 2018 BMW 340I

The radiator failed due to rocks flying through the grill and smashing the radiator causing coolant to flow out of the radiator which could cause deadly issues if a car has no coolant while operating. Bmw knows this is an issue and refuses to warranty/recall the parts. They know its an issue because after 12/17 every 340i came with a rock guard to protect the radiator but every car before that was just left to be victim of a potentially deadly situation including mine (manufactured 10/17). Bmw refuses to acknowledge the problem but the addition of the rock guard to cars after 12/17 should be enough evidence to show they knew it was an issue. Now all 2016-2018 m sport f30 chassis built before 12/7 are susceptible to this deadly situation and bmw refuses to cover for any damages even though they know it's a serious issue and they won't even cover the rock guard
