2018 BMW 230I

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. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.

Incident

May 15, 2026

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. They referred to it as a RECALL on the verification paperwork.(see attached) I submitted the paperwork to BMW verifying the work was done and the invoice we paid. They responded a few days later, rejecting our request for reimbursement. They wouldn't even give us the amount it would have cost them to fix it. They called it a "SERVICE ACTION" not a "RECALL" and therefore not eligible for reimbursement. SO MY FAMILY IS PUT AT SIGNIFICANT RISK DUE TO A DEFECTIVE PART, AND THEY GET OFF WITHOUT SPENDING A DIME.

I HAVE A 2018 2 SERIES XDRIVE CONVERTIBLE WITH 18' PIRELLI RUN FLAT TIRES. THIS IS MY SECOND 2 SERIES. I HAVE HAD 6 OF THESE TIRES BLOW DUE TO POTHOLES OVER THE TWO CARS I HAVE HAD OVER 4 YEARS. THE LAST ONE THAT BLEW WAS ON FRIDAY ON I65 JUST SOUTH OF LOUISVILLE. I HAD TO WAIT 4 HOURS FOR TOW TRUCK TO TAKE IT TO BMW OF LOUISVILLE. I PROCEEDED ONTO NASHVILLE. I PICKED THE CAR UP ON THE FOLLOWING MONDAY. THE TIRES ARE 18' PIRELLI CINTURATO P7 A S RFT RUN FLAT. THIS IS A CHRONIC PROBLEM WITH THIS CAR. MY BMW SERVICE PERSON SAYS THIS HAPPENS SO OFTEN WITH THESE CARS. THIS BLOWOUT PATTERN IS NOT ACCEPTABLE. I NEED NOT TO BE TO BE WORRIED ALL THE TIME THAT A TIRE IS GOING TO BLOW WHEN A POTHOLE IS HIT. ESPECIALLY ON THE HIGHWAY. I MUST GET THEM CHANGED. I THINK THIS COULD BE A DEADLY PROBLEM. IT SHOULD BE LOOKED INTO BY NHTSA.

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.

The electrical system of BMW vehicles has been subject to an ongoing development process over the last few years. This has led to increased demands being placed on the battery. This document covers important information for the dealer on how to handle “discharged battery” complaints.

At low outside temperatures (below 40 degrees F) and slow driving speeds (i.e. when parking, maneuvering)with a large steering angle, the front end can be slightly axially misaligned. This can be felt (jerking)/ heard via an acoustic acknowledgement (clunk) as seen at the 11 second mark of the video. See attached video V36 01 21.
