BMW Water Pump Recall: 720,796 Vehicles Told to Park Outside

1. Find your 17-character VIN. It is on the lower driver-side corner of the windshield, on the sticker inside the driver door jamb, and on your registration and insurance card.
2. Match your badge. Look for a 28i-style badge (228i, 328i, 428i, 528i, X1/X3 28i, X4 xDrive28i, Z4 sDrive28i) or the X5 xDrive40e plug-in hybrid, then compare it with the table above.
3. Run the official lookup on December 25, 2026. Enter your VIN or license plate at NHTSA.gov/recalls. The campaign number is 26V733.
4. Until then, call BMW at 800-525-7417. Ask whether your VIN is included, and have the VIN ready.

The earlier recall (24V608) blamed fluid from the crankcase ventilation system dripping onto the water pump’s plug. The fix was a protective shield to divert that fluid, plus an inspection of the connector and wire harness plug, with the pump or harness replaced if needed.

The 2026 filing describes a different concern. BMW says laboratory testing found degradation and localized embrittlement of the connector’s plastic (polybutylene terephthalate, or PBT), and later scans identified cracks in the connector. Cracks give moisture a path into the pump, which can short-circuit.

BMW’s chronology also shows the explanation shifting. An incident on a previously repaired 3 Series first pointed toward a possible improper repair, but later analysis of returned pumps confirmed embrittled connectors. The filing says the root cause of the material degradation had not yet been determined. That is why the shield alone may not be enough, and why NHTSA says vehicles repaired under 24V608 must be repaired again.

Incident count: BMW reported approximately 10 US incidents that relate, or may relate, to this issue. They involved vehicles that had received the earlier repair. BMW says it is not aware of any crashes or injuries.

• Park outside, away from your house, any garage or carport attached to a building, and other vehicles. NHTSA’s wording is “outside and away from buildings and other vehicles.” The alert doesn’t give a minimum distance, so more space is better.
• Don’t wait for symptoms. The recall filing lists no warning signs, and the risk exists while the car is parked and switched off. No smoke, smell or dashboard light doesn’t mean a car is clear.
• Owner letters are planned to be mailed beginning December 25, 2026, and NHTSA says VIN and license plate lookup opens that day. Owners are then to be notified again when the remedy is ready.
• Cost: the repair will be free at an authorized BMW center. If you paid for a related repair yourself before the notice, BMW’s filing says you may be eligible for reimbursement under its reimbursement plan. Keep your invoices.
• Don’t improvise a fix. The notices we reviewed don’t suggest any do-it-yourself step, such as disconnecting the battery. Ask BMW before trying anything.

Apartments, shared garages and street-only parking make this advisory hard to follow. These are practical suggestions, not official instructions from BMW or NHTSA:

• Renters and HOA residents: ask your landlord, building manager or HOA for an outdoor space now, and put the request in writing with a link to the NHTSA alert.
• Attached garage or carport: these are the situations the advisory is meant to avoid. If you have a detached or open outdoor option, use it.
• Street parking: where rules allow, leave space between your car and neighboring vehicles and buildings.
• Ask BMW about help. The notices published so far don’t describe loaner cars or rental coverage. Call 800-525-7417 and ask what assistance is available.
• Check your insurance. Fire damage is generally handled under comprehensive coverage, but policies differ. Ask your insurer how this recall affects your coverage. This is general information, not insurance advice.

These are general vehicle-fire safety steps, not recall-specific instructions from BMW or NHTSA:

1. If you’re driving, pull over somewhere safe and switch off the engine.
2. Get everyone out of the vehicle.
3. Move well away from the car and from traffic.
4. Don’t open the hood or try to put the fire out yourself.
5. Call 911.

• What the repair involves. BMW says the remedy is in development and hasn’t described it.
• When parts will arrive. No repair date has been published.
• The root cause. BMW’s filing says the cause of the connector material degradation had not yet been determined.
• Whether the scope changes. Recall populations can be revised, which is why a VIN check matters more than a model-year check.
• Loaner or rental help. None of the published notices address it.

We update this page as NHTSA and BMW publish new information.

BMW has issued several park outside advisories, and owners often confuse them. They are separate campaigns with different defects:

• This recall (26V733): water pump electrical connector, 2012–2018 models, 720,796 vehicles.
• 2025 starter recall: about 196,000 model year 2019–2022 vehicles (plus some Toyota Supras built by BMW) where the engine starter can corrode, overheat and short-circuit.
• 2026 plug-in hybrid starter recall: about 29,000 BMW plug-in hybrid sedans from model years 2016–2020 with a related starter issue.

A car can have more than one open recall. Enter your VIN at NHTSA.gov/recalls to see all of them.

• Buyers: ask for the VIN before you visit, and compare the model, year and variant with the table on this page. Ask whether the car had the 2024 repair, and remember that it still needs the new one.
• After December 25, 2026: run the VIN on NHTSA.gov/recalls and save a screenshot of the result.
• Sellers: tell buyers up front if your car is a listed variant. Being open about the recall status builds trust and avoids disputes later.
