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
Fuel Tank Filler Hose Collapse - unable to refuel and vehicle remains stranded.
RETURNING FROM A LOCAL GROCERY STORE I DROVE INTO OUR GARAGE AND SHUT OFF THE ENGINE. IMMEDIATELY I HEARD A LOUD POP FROM THE ENGINE COMPARTMENT, LIKE FROM A FIRECRACKER, AND I SAW BLACK SMOKE COMING FROM THE HOOD AND FROM THE LEFT WHEEL WELL. I IMMEDIATELY TRIED TO RESTART THE CAR TO DRIVE OUT OF THE GARAGE. NOTHING WORKED SO I PUSHED THE CAR OUT OF THE GARAGE BY HAND AND RELEASED THE HOOD LATCH. BY NOW THE HOOD'S EXTERNAL SAFETY LATCH WAS SO HOT I COULD NOT RELEASE IT. WITH THE HOOD CLOSED, I WAS UNABLE TO EXTINGUISH THE ENGINE FIRE USING A 15 LB CO2 AND A 5 LB ABC EXTINGUISHER. THE CITY FIRE DEPARTMENT ALSO WERE UNABLE TO EXTINGUISH THE FIRE UNTIL THEY SAWED THE HOOD IN HALF. THE 2 1/2 YEAR OLD CAR WAS A TOTAL LOSS. A EXPERT FROM BMW OF NORTH AMERICA INSPECTED THE CAR REPORTING THAT WAS TOO MUCH DAMAGE TO DETERMINE THE FIRE'S CAUSE. BMW NA CALLED TO REPORT THE RESULT NOT THEIR INVESTIGATION AND SAY THAT NO WRITTEN REPORT WAS AVAILABLE, ONLY THE VERBAL VERBAL FONECON.
