We heard a whining sound under the hood on November 1st, 2025. Prior to noticing this noise, there were no warming lamps or messages appearing. Following a short drive we smelled burning in the garage. We did not drive the vehicle the following day and intended to take it to our mechanic on Monday morning, the 3rd. Upon trying to start the car it was dead. We had to have it professionally jumped as standard jumping with our personal jumper cables would not start it. Our mechanic explained both the battery and the water pump would need to be replaced. Upon further examination, he realized that the cable or water pump harness that connects the two had been burned and discovered a recall on thousands of 2017/2018 X4 models. He called us and encouraged us to take it to BMW as he found the recall and assumed they would take care of it. Upon calling our local dealership, they looked up our VIN and said our model was not part of the recall. We proceeded with the repair as we had to have our vehicle. Once those parts were replaced, it was also discovered that the issue caused the entire DME/ECU unit to go bad. Our mechanic then ordered that directly from BMW. Once in he had it reprogrammed and we got the car back. We were without a vehicle for a month. We would ask that you please review this as it's clear, this was the exact issue that has affected thousands of other BMW X4 Models. It is a safety issue as we smelled the burning in our garage and learned later that it could have started a fire either while driving it or in our garage at home. Our VIN should be included in the recall. Upon calling BMW of North America Customer Service, they told us to file a complaint on nhtsa.

Electrical SystemAug 2025 · ODI 11682608Details +Close −
The water pump was found to have extreme corrosion after several other components on the car were damaged from the coolant leak into the electrical system. The car was suddenly losing power while driving and the DME was smoking, potentially causing an engine fire. So far the water pump, Digital Motor Electronics (DME) and throttle body were replaced over a 15 day period in service. The day the car was picked up, the chassis stabilization light came on and the dealership was receiving codes saying multiple additional electrical systems are now triggering the codes. The car was back at the dealer for service and now they are saying even more systems have been damaged by the leak. There is currently a recall on the water pump for this model and year, although this exact VIN is not included in the recall. Initial overheat warnings came on July 22, 2025 just prior to the car going in the shop although the dealer didn't see that the car was overheating. The fault codes were coming up as electrical. Only the dealer has inspected the car thus far. I content this car should have been included in the recall for the water pump as the description of the recall fits the exact damage to the water pump in my car.

Investigations
1 NHTSA investigation on record
Investigations are agency reviews, not findings that a vehicle is defective.
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.
