Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Bmw 2000 540I, v8, failure (cracked, loss of coolant) of upper radiator hose connector. I had 3 1/2 yrs/45,000 miles on the car. Plastic component widely known among owners to be prone to failure. Thanks to their advice on warning signs, I was able to stop under control and get repair without major incident; other unsuspecting drivers have been, and will be, less fortunate. To Bmw's credit, they replaced my radiator under warranty. But this does not excuse a known design deficiency.”

NHTSA complaint #10030308, filed 2003-07, 45,000 miles

“Water pump failure.this is a known defect that involves a high percentage of the e39 540I Bmw. The failure of the pump is known to happen between 5000-60000 miles and can put the driver in danger and cause unnecessary expensive repairs to be incurred on a car of this caliber. The water pump failure in my case destroyed the main drive belt leaving me with out power steering, brakes, alternator etc. E39 owners who have had this experience should be reimbursed for the repairs and costs associated with the faulty design and problems associated with the water pump and cooling system.”

The radiator fan blades detached, dented the hood, which caused the paint to peel and then fell to the ground.. The failure mileage was 111,000. The contact was in the process of towing the vehicle to the dealer for diagnostic testing. The failure mileage was approximately 111,000.”
