NHTSA defect investigations
Federal safety investigators have looked into a possible defect involving the 2015 BMW 435i:
Desiccated Air Bag Inflator Rupture
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.
What 2015 BMW 435i owners say
Engine & cooling
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. …
The engine vehicle power died down while driving in the middle of the road , this occurs 4 to 5 times within 20 minutes time duration, I have to put the car emergency lights on for 4 separate times within 20 minutes duration ,and almost got hit by the cars from behind the vehicle. Prior to this incident, about 2 weeks ago, the driver side mirror was not working ,for over 5 minutes I was trying to adjust the mirror through the controls but mirror was not responding and unable to do so, while I was merging the freeway, I cannot see the truck behind me while merging the busy freeway, and almost got hit by the truck. Roseville BMW was unable to diagnose any problems with vehicle and they want me to take back the car to drive. …
