NHTSA defect investigations
Federal safety investigators have looked into a possible defect involving the 2018 BMW 230i:
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.

The coolant pipe from the engine cylinder head to the coolant reservoir broke unexpectedly which left us stranded on a narrow shoulder on the side of a busy highway with cars streaming by at high speed. A warning lamp directed us not to drive. Our safety was absolutely put at risk obviously. We had it towed to the closest shop doing BMWs. We had it fixed at significant expense. 5 months later, received a letter from BMW (see attached) wrote us admitting they had found this defect and were offering to replace the defective equipment at their cost if we brought it to the dealer. I called their customer service line who directed me to visit their nearest dealership an hour away and if the work we paid for was done correctly they would reimburse us. We drove and had the Dealer's mechanics verified that the work was done correctly. …
Driving down the freeway at 65mph, car engine just shuts down. No power steering, no way to get over. Car display says drive train error. Car got towed to the dealer for service, dealer "fixes" issue. 2 days later, exact same thing happens again on the freeway at 65mph. Engine just shuts down. Towed back to the dealer. Still there, no fix yet. However, how is my wife supposed to feel safe in this car now. It can die on the freeway at anytime and you have no power and traffic is zooming by.
