My mother was in the passenger seat and the seat belt buckle would not allow the tongue to be inserted. After several attempts we got it in but when we got home I tried to engage the seat belt several times, I tried to lubricate the buckle no luck... I ordered a new buckle. The BMW dealer said there had been no other complaints and it was not under recall. As soon as I get the new part I will retain the buckle if needed.

Defect investigations
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 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.

What 2012 BMW 128I owners say
Most recent owner complaints, unedited.
Prior to August 2024, this vehicle operated with zero check engine lights or drivetrain faults. In August 2024, BMW of Pittsburgh executed federally mandated Safety Recall 23V‑707, which required opening the cylinder head. Immediately following this service, the Check Engine Light began illuminating persistently.On or about October 3, 2024, an independent diagnostic scan at Bobby Rahal BMW pulled BMW Factory Code 002A89: Exhaust VANOS Camshaft Mechanism Fault (Mechanical Sticking/Flow Restriction). Technicians at Bobby Rahal BMW explicitly instructed me to return the car to BMW of Pittsburgh because they suspected the original VANOS safety recall repair was botched.On October 28, 2024, I returned the vehicle to BMW of Pittsburgh to address this issue. Their technicians opened the engine block assembly a second time, yet failed to correct the defect. Following this second visit, the check engine light continued to come on intermittently. The vehicle began suffering rough idling, difficulty starting, and dangerous stalling events during operation. Cycling the ignition on and off provided only temporary relief.The check engine light has now become permanently illuminated. The safety hazards have severely escalated into a protective engine "limp mode," causing violent drivetrain shuddering and a catastrophic loss of driveability. BMW of Pittsburgh refuses to honor the recall workmanship, demanding a predatory $6,000 out-of-pocket teardown fee to bypass their liability. The manufacturer (BMW North America) has been notified under Case Reference VH78028, but the safety defect remains unaddressed, and the vehicle is completely unsafe to drive.
Due to BMW using plastic parts when you live in Hot and cold environments the plastic begins to mold to other plastic parts and pvc diaphragms tear rather easy causing rough idle , stalls and can cause over revving and send a car into another car while in gear. The cheap plastic cause oil leaks and when oil gets low cause engine failure as well.
On February 25, 2026, BMW of South Miami performed the VANOS safety recall repair on my vehicle. The repair order documented that VANOS bolts were missing and retrieved from the engine oil pan and that VANOS components were serviced. Within approximately 24–48 hours of picking up the vehicle, the check engine light illuminated and the vehicle began operating abnormally, including rough idle and irregular shifting. The vehicle stored diagnostic fault code P054B (camshaft position timing over-retarded), which directly relates to camshaft timing and the VANOS system involved in the recall repair. I returned the vehicle to the dealership for further diagnosis. The dealership stated an aftermarket camshaft position sensor with two O-rings was installed and removed one O-ring to correct the gap between the sensor and the camshaft reluctor wheel. The faults were cleared and the vehicle was returned to me. However, the check engine light returned again the following morning upon cold start, indicating the issue was not corrected. My service advisor has since stated that replacing the camshaft position sensor is not part of the recall repair and the dealership has declined to repair the vehicle under the recall. Because the malfunction appeared immediately after the VANOS safety recall repair and involves the camshaft timing system connected to VANOS operation, I believe the recall repair may not have been properly completed or corrected. I am requesting that the federal safety agency review this matter as a potential recall effectiveness issue, as the safety recall repair appears unresolved and the vehicle continues to experience faults related to the system that was repaired.

Takata recall -- after months of waiting for a replacement airbag, I received a notice from bmw in late september that the replacement part is available and that I should get my car in. I scheduled an appointment with kuni bmw on october 17, 2017 but they called that morning and said that they didn't have the parts but would call me when they do to reschedule. I followed up on october 30 and the service department said that they still can't help me but that I am on their priority list when the part comes in. So -- in spite of the fact that bmw has notified me that my car needs to be fixed, my local dealer can't do the job. It's been a month and there are no replacement airbags available!
