BMW Recalls Over 720,000 U.S. Vehicles Over Water Pump Fire Risk
BMW recalls over 720,000 vehicles in the U.S. due to a water pump fire hazard, urging owners to park outdoors. The defect persists despite a previous 2024 fix, prompting a new safety campaign.
German automaker BMW has issued a recall for more than 720,000 vehicles in the United States due to a fire risk, urging owners to park outdoors and away from other structures until repairs are completed. According to a notice published by the National Highway Traffic Safety Administration (NHTSA), the defect stems from an electrical connection issue in the water pump, which can allow moisture to penetrate, leading to a short circuit and potential fire. The danger exists even when the vehicle is parked and the engine is turned off.
The recall covers a wide range of models manufactured between 2012 and 2018, including the 3 Series, 5 Series, and Z4 from 2012–2016, X1 models from 2012–2015, X3 models from 2013–2017, X4 models from 2015–2018, and the X5 xDrive40e plug-in hybrid from 2016–2018. It also includes certain 2 Series and 4 Series models, encompassing coupe, convertible, and Gran Coupe variants. The recall applies to specific vehicles within these production years rather than the entire lineup.
According to recall documents submitted by BMW to U.S. authorities, the electrical connector in the water pump can wear out and crack over time, permitting moisture to enter electrical components. This can cause overheating and, in rare cases, a fire. Company testing revealed that the plastic material of the electrical connector has become brittle, with cracks discovered in several components. However, what makes this recall unusual is that it involves a defect that was already addressed in a previous recall in August 2024.
Under the previous recall, a protective shield was installed to prevent liquids from contacting the water pump's electrical connection, and components were inspected and replaced where defects were found. However, in April 2025, a report emerged regarding abnormal overheating in the electrical connector of a 5 Series vehicle that had already undergone the fix. In June of that year, another report from the U.S. noted scorching signs on the electrical connection of a 3 Series car that had also been serviced. Initially, officials suspected faulty repair work, but subsequent cases of overheating appeared in other fixed vehicles.
By early 2026, BMW launched a thorough investigation in cooperation with its water pump supplier. The tests showed that the plastic material in the electrical connector can degrade and crack, allowing moisture intrusion even after the shield installation from the previous recall. Following these findings, the company decided on October 28 to initiate a new recall. BMW reported that it was aware of approximately ten cases in the U.S. potentially linked to the defect, with no reported accidents or injuries. The company estimates that the defect rate is below 0.1% of all recalled vehicles, but opted for a full recall due to safety risks.
At this stage, BMW is still developing a permanent solution, meaning a repair date has not yet been set. According to the NHTSA, vehicle owners are expected to receive notification letters by mail during December and will later be invited to authorized service centers for a free repair. Owners whose vehicles were serviced under the 2024 recall will also need to return to the garage. Until repairs are finished, the company advises parking in open areas away from buildings to minimize fire risks, while stopping short of an absolute driving ban.
