NHTSA Complaint #11630787 — 2017 BMW 540I

Vehicle has severely poor quality coolant hoses made from poor quality material that cannot withstand the flow of pressure within the coolant system process. Leading to the hoses deteriorating from internal pressure thus causing the coolant hoses to leak. The coolant sensors only indicate low coolant levels when there is, 1 and 3/4 inches of coolant liquid left which is 70% lower than the minimum coolant line within the main coolant reservoir which can then lead to engine failure that could result into a vehicle accident or wreck causing injury or even death. This problem has been commonly known and reported throughout the BMW community for BMW’s with the Generation 1 & 2 B58 engine models. I have taken my vehicle to two local BMW Dealerships in my surrounding area and have been notified by those dealerships that the hoses have been tested and tried under extreme conditions and that the quality should not be pertaining to the coolant leak issue rather that the coolant leak issue is effected by age and wear and tear and possibility of environmental debris or other environmental factors depending on the state and area the vehicle is based and driven in. I find that statement given by both dealerships to be inaccurate as myself and other BMW owner’s have had these issues within 50,000 miles or less and the vehicle being garage kept and only obtained between 10,000-12,000 miles annually. I sincerely branch out to the National Highway Safety Administration for additional support in holding the manufacturer accountable for it’s irresponsibility to not take corrective action on the documented common issue within the Generation 1 & 2 B58 engine models.
