BMW Recall Tells 720,796 Owners to Park Outside Over Fire Risk
A water pump plug can short circuit and start a fire with the engine off, and cars already fixed in 2024 need a new repair that BMW has not built yet.

A new BMW recall covers 720,796 vehicles in the US because a water pump connector can short circuit and start a fire, even when the car is parked and switched off. The National Highway Traffic Safety Administration (NHTSA, the US auto safety regulator) is telling owners to park outside, away from buildings and other vehicles, until a repair is done.
The catch is that the repair does not exist yet. These are largely the same 2012-2018 cars BMW already recalled in 2024, and NHTSA says vehicles fixed under that campaign will need the new remedy too.
What is wrong in the BMW water pump recall?
According to NHTSA recall campaign 26V-733, an improperly sealed electrical connector on the electric water pump may be exposed to water. Moisture can then cause a short circuit, which increases the risk of a fire.
The water pump circulates coolant to keep the engine at a safe temperature. In these cars it is electric, so it carries a live electrical plug in the engine bay. That is why the risk does not disappear when the ignition is off.
BMW is aware of about 10 US incidents that may be related, Reuters reported. All of them happened in cars that had already received the 2024 fix, and no crashes or injuries have been reported.
Why didn't the 2024 fix work?
The earlier recall, 24V-608, blamed liquid from the crankcase ventilation system dripping onto the pump's plug. Dealers inspected the parts, replaced damaged ones and added a splash shield over the connector.
BMW's new filing points at the connector itself, BMWBlog reported. Its material can degrade and let moisture into the pump, and BMW's testing found brittle, cracked connectors. A shield on top cannot stop plastic that is cracking underneath, so BMW decided on Oct. 28 to recall the cars again.
Which BMW models are affected?
The recall covers four-cylinder versions of the 2 Series, 3 Series, 4 Series and 5 Series, plus the X1, X3, X4, Z4 and the X5 xDrive40e plug-in hybrid. BMWBlog notes that all use the N20 or N26 engine, BMW's 2.0-liter turbocharged four-cylinder.
The campaign is limited to the 2012-2018 model years, so newer cars such as the current BMW 3 Series fall outside it. The full list of model years is in the table at the end of this article.
When will BMW owners get a fix?
BMW has not said what the new repair involves or when parts will be ready. Once it is available, dealers will do the work for free.
Owner notification letters are due in December, with mailing starting on Dec. 25, 2026. On the same day, VINs (the 17-character vehicle identification number on the dashboard and registration) become searchable on NHTSA's recall lookup.
What should owners do now?
- Park outside and away from your house, garage, carport and other cars, even if your car had the 2024 repair.
- Check your model and year against the table below, and run your VIN on NHTSA.gov once the lookup opens on Dec. 25.
- Call BMW customer service at 1-800-525-7417 with questions, or NHTSA's Vehicle Safety Hotline at 888-327-4236.
- Keep your contact details current with BMW so the owner letter reaches you, especially if you bought the car used.
The sources cover only the US campaign. BMW has not announced a matching action for other markets so far, so owners elsewhere should check with their national regulator or dealer.
Our take
A repeat recall is a bigger problem for BMW than the first one. Owners who already went to a dealer in 2024 now learn the fix addressed the wrong cause, and they have to change how they park for weeks without a confirmed repair date.
For a 10-year-old car parked in a home garage, "park outside" is a real burden, but the advice is clear. Safety advice that changes daily habits tends to be ignored over time, a pattern we have also seen in other car safety stories. BMW is meanwhile pushing new models such as the iX3 M60, but for these owners the priority is a working repair.
