Defect investigations

Desiccated Air Bag Inflator RuptureOpened September 17, 2021, still open

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 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 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.

My 2015 BMW 320i (VIN: [XXX]) intermittently loses power steering assistance while driving, creating a serious safety concern. BMW Service Bulletin SI [XXX] describes similar EPS-related issues. Given the nature of this failure, I believe it deserves further review beyond the vehicle’s warranty status.

The fuel system was causing my engine to shut down, and I got it replaced at a mechanic. About some time later, after fixing the fuel system, I received a letter from BMW telling me that they had extended the warranty on the Fuel tank, but when I took it in, they said that there was no such extended warranty. The letter is from April 2022, but I just recently found it.

My 2015 BMW 320 is having a performance issue. After I diagnosed this is due to corrosion on the wastegate actuator and has failed. The bushing and part corroded and the rod is dangling. This should be covered by the extended warranty on the part as it’s a known defect failure by BMW

Vehicle continues to have lighting and electrical issues. Particularly, the left rear turn signal. I’ve repaired it 5 times and it burns out immediately. Dealer assured me they would find issue. Still burned out next day again. Notified dealership and they just want you to keep bringing it back but won’t issue a recall despite the plethora of complaints online about the same issue.

The gas tank on my BMW 320i 4 door sedan is leaking gas. Yes; it is available for inspection upon request. I had picked up my son from school and ran an errand. We stopped for gas when we noticed the gas was leaking as soon as we filled up the tank. We were around the corner from our home and drove home very slow. We were prepared to stop and pull over if necessary as we were afraid of the vehicle catching fire. I have an appointment with Niello BMW at 8am on 9/22/25 in Sacramento, CA on Fulton Ave. There were no warning lamps/messages or other symptoms prior to the issue. I never received any recall notification.

I have barely driven this BMW 320i from 2015. It is a well taken car parked in the garage. It has 33,000 miles on it. The check engine light came on so I brought it in for a diagnostic. The error is N63R Engine - Replace Wastegate Actuators and Program the Vehicle. The mechanic told me most BMW's in 2015 had a recall for this issue and this car should have a recall. So, I called BMW and they said it does not have a recall. I checked on the federal safety agency site and the car does not have a recall. However, after some research, I found that many models from this year have a recall for this exact issue. This BMW320i from 2015 should also have this recall! There is no coincidence that the Wastegate failed in several models in the same year. To exclude this model from the recalls is unfair.

The contact owns a 2015 BMW 320I. The contact stated that after his wife had refueled the vehicle, he noticed that the vehicle was leaking fuel on the driver's side rear. There was a puddle of fuel on the ground. There were no warning lights illuminated. The contact called an independent mechanic who stated that the failure was due to the pressurized fuel system. The contact called the local dealer and was informed that there were no recalls on the VIN. The vehicle was not diagnosed or repaired. The manufacturer was contacted, and the contact was referred to the federal safety agency Hotline. The failure mileage was approximately 145,000.

Timing chain guide failure, causing engine to stop working

The engine would completely shut down while driving you had to completely take foot off gas petal because it would not excellent to make the car run it would almost come to complete slow down and stop you could then push gas and it would pick up and start running again.was worse when raining. Then the brakes got to where they would not stop and would lock up.Iwas on busy road and on interstate when it happened several times I could have been hit in the rear end and it would have caused a major collision. There was no warning lights come on at any point and timethen the brakes started where they would get hot and start smoking and eventually they locked up could not even drive the car . I didn't have the money to try to get it fixed so my 2015 BMW 320i sit for months before I could get it looked at had to replace frount and back rotors,calipers and brakes, ABS system replaced. When they checked it out the man at KADENZA AUTO REPAIR SHOP said that was only the second BMW that they had worked on that had this problems and didn't know why or what caused the problem. They did the repairs but couldn't guarantee that it wouldn't happen again said it could be a manufacturer defects. It was really dangerous when it started doing it because I could have been hit in the back of the car and it would have caused a major car pile up accident. It started doing it several months back because I wasn't able to drive it for several months had to tow it in when I took it to KADENZA AUTO REPAIR .They specialize in foreign and domestic cars.
