When owners complained
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single

NHTSA investigations into the 2015 BMW 435I
An investigation is the step before a recall: the agency has seen enough
complaints to look into a pattern itself. An open one means it thinks
something may be wrong and nothing has been fixed yet.
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants.

ENGINE
I am submitting this complaint regarding a 2015 BMW 435xi (N55 engine, ~79,000 miles) that suffered a sudden and complete engine failure due to the oil pump drive chain. While driving at highway speed, the vehicle experienced an instant loss of oil pressure and engine seizure without any warning lights or prior symptoms. I barely managed to steer the car to the shoulder and avoid being struck by surrounding traffic. This was a serious safety hazard, as the loss of power and steering control occurred in active highway conditions. Inspection revealed a catastrophic internal failure of the oil pump drive chain. This is not related to neglect, lack of maintenance, or external damage—the vehicle had received an oil service at a BMW dealership only two months prior. Importantly, the N55 engine uses the same oil pump chain and guide architecture as BMW’s N20/N26 4-cylinder engines. BMW has already acknowledged premature failures of this system in those engines and provided extended warranty coverage. The fact that this defect is now occurring in the N55 platform demonstrates a broader systemic issue. This failure at relatively low mileage creates a significant safety risk to drivers and passengers, as well as other vehicles on the road. A sudden seizure of the engine at highway speed leaves little to no opportunity to maneuver safely and avoid collisions. I urge the agency to investigate this issue as a potential design defect affecting the N55 engine family. BMW should be required to provide recall or warranty remedies similar to those extended for the N20/N26 engines. Thank you for your attention to this serious safety matter.

FUEL/PROPULSION SYSTEM
I own a 2015 BMW 435i from Checkered Flag (Jaguar) in about 2017. The car is currently experiencing a fuel pump failure of exactly the type that is described here: [XXX] . Your VIN lookup does not show my car is covered by the recall, even though my car is exactly the make and model described in the recall notice. Moreover, the defect my car is experiencing is exactly the defect described in the recall notice. It makes little sense that some cars of this make and model would have a fuel pump problem but not others; it is far more likely the fuel pumps are common to all cares of this make and model and somehow my VIN was left off the recall list. I’d like to ask you to look further into it, as it appears to be quite a coincidence that my fuel pump failed in the manner described in the recall notice.

IMPROPER PLATING ON FUEL PUMP MAY RESULT IN STALL - WHICH IT HAPPENED TO ME ON THE HIGHWAY. CALLED BMW AND THEY SAID NO RECALL ON MY CAR, BUT WHEN YOU LOOK UP A 2015 435I, IT SHOWS IT HAS THAT RECALL. BMW WANTED TO CHARGE ME FOR A DIAGNOSTIC, WHEN I FEEL THEY SHOULD TAKE IT AS A RECALL. MY FIRST PROBLEM WITH BMW, AND THEY DON'T SEEM TO CARE.
