I am submitting a safety complaint regarding my 2016 BMW 435i. My vehicle experienced a sudden water pump failure while I was driving on the freeway. Without warning, the vehicle immediately entered “limp mode,” causing a sudden and dangerous loss of power in active traffic. This created a serious safety hazard because surrounding vehicles had to quickly avoid my car to prevent a collision. I am aware that there is an existing recall and/or known issue involving electric water pump failures on certain BMW vehicles, including similar 2016 BMW models, but my VIN does not qualify for recall coverage despite experiencing the exact same failure and safety-related symptoms. I believe this defect should be investigated further because it creates a substantial risk to driver and public safety when the vehicle suddenly loses power at highway speeds. Additionally, my vehicle has an ongoing issue with the parking collision warning/driver assistance system. The system will randomly trigger collision warnings and emergency alerts even when I am driving safely with no obstacles or vehicles in front of me. These false warnings are distracting and could potentially cause unsafe driver reactions or unnecessary braking events. I request that the federal safety agency investigate both issues: 1. Sudden electric water pump failure causing immediate limp mode and loss of power while driving. 2. Malfunctioning collision warning system producing false collision alerts without hazards present. These issues present significant safety concerns and appear consistent with known defects affecting similar BMW vehicles. Vehicle Information: * Year: 2016 * Make: BMW * Model: 435iThe I would like to mention I am an active first responder (EMT) and would recommend addressing these safety concerns

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 2016 BMW 435I owners say
Most recent owner complaints, unedited.
The contact owns a 2016 BMW 435I. The contact stated that while starting the vehicle, the engine stalled. The battery warning light was illuminated. The vehicle failed to restart and was towed to the dealer. The dealer determined that the VANOS bolts had failed and needed to be replaced. The vehicle was not repaired. The contact related the failure to the federal safety agency Campaign Number: 23V707000 (Engine and Engine Cooling); however, the VIN was not included in the recall. The manufacturer was made aware of the failure and advised the contact to file a complaint with the federal safety agency Hotline. The failure mileage was approximately 107,000.
Water pump causing no start and high battery drain.
Airbag sensors are defective. Vehicle states that restraint system is faulty.
The contact owns a 2016 BMW 435I. The contact stated while driving at slow speeds, the chassis stabilization warning light was illuminated. The contact took the vehicle to the local dealer, where it was diagnosed with needing the electric power steering (EPS) to be replaced. The vehicle was not repaired. Upon investigation, the contact associated the failure with TSB: SIB321216, however the VIN was not included. The manufacturer had been informed of the failure. The failure mileage was approximately 70,000.
A strong odor of gasoline was noted and it dripped from the tank when the car was driven. Mechanic reported the tank had a leaking seam which he would patch with plastic, so the car can be used while waiting for a replacement tank.
water entered the air intake at front of vehicle and caused engine damage.
Back up camera cuts off when in reverse all the time
With no evidence of foreign object damage, sunroof exploded on a clear freeway at freeway speed. Interior temp 74f, ambient 93f. Sunshade was closed, but glass fragments leaked through the vent holes in the sunshade. Paint damage to trunk. Potential safety hazard to other motorists. Of note the glass is tempered, not laminated, hence the elevated potential for injury and damage.
I was driving my vehicle in dallas, tx and multiple times the car engine & all power shut off, and the car shifted itself into neutral. I suspect there is an issue with the auto stop/start feature or something more. A car should never shift itself into reverse when you are driving. Both times almost caused an accident on the freeway as the car came to a sudden halt and I had no control with it shifting into n. The bmw dealership & bmw are claiming nothing is wrong. I do not feel comfortable accepting this vehicle back until this issue is resolved and feel the government should look into any issue of a vehicle automatically shifting into n and powering down while driving.
