2023-2024 Fisker Ocean Coolant Pumps: Recall, Failures, and Replacement Guide
The Fisker Ocean uses multiple, non-interchangeable electric coolant pumps; a failure in one specific pump has led to a widespread recall and can disable the vehicle.
- A faulty cabin electric water pump (part number FM2930200022A) is subject to a major safety recall (NHTSA 24V-499) that can cause the vehicle to suddenly enter a low-speed 'limp mode'.
- The Fisker Ocean has multiple, non-interchangeable coolant pumps. You must match the part number from your original pump exactly before buying a replacement.
- Due to high-voltage systems, replacement should only be performed by qualified technicians familiar with EV safety procedures.
- Fisker's 2024 bankruptcy may complicate access to new parts and free recall repairs, making warrantied used OEM parts a practical alternative.
Understanding the Fisker Ocean's Multiple Coolant Pumps

The 2023-2024 Fisker Ocean is equipped with a complex liquid-cooling system that relies on at least three or four separate electric pumps. This is a critical point for anyone needing a replacement: the pumps are not interchangeable. A pump for the battery cooling system cannot be used for the cabin heater, and vice-versa. The most important step before purchasing a used pump is to physically inspect the original part and match the part number exactly.
Compatibility Warning: The Fisker Ocean uses several different electric coolant pumps for its various thermal management systems (high-voltage battery, drivetrain, and cabin heater). These parts are not interchangeable. You must verify that the part number on your original pump matches the part number on the replacement part exactly to ensure compatibility.
Known Issues and Recalls: The Cabin Electric Water Pump

A significant issue has been identified with the cabin electric water pump (sometimes abbreviated as EWP_H) in 2023-2024 Fisker Ocean vehicles. This led Fisker to issue a voluntary safety recall for approximately 7,545 vehicles in the U.S. and thousands more in Canada and Europe.
The problem is that a failure within the cabin pump's electronics can cause a loss of communication on the vehicle's data network (specifically, the LIN 6 bus). This communication loss triggers the high-voltage battery management system to enter a protective "limp mode," which severely restricts battery power to just 8.5 kW. This dramatically reduces the vehicle's speed to approximately 10-20 mph, creating a significant safety risk if it occurs in traffic.
The official remedy for the recall is to replace the faulty cabin electric water pump with a new, updated version that features an improved conformal coating on the internal circuit board to prevent failure. 🎬 Watch: How to remove and seal the pump electronics However, due to Fisker's bankruptcy filing in mid-2024, obtaining recall service can be challenging.
Which Pump is Part of the Recall?
The recall specifically targets the cabin electric water pump. Search results and parts listings identify part number FM2930200022A as the "Cabin Electric Water Pump (EWP_H)". This is the pump most likely to be the subject of the recall.
Symptoms of a Failing Coolant Pump

A failing coolant pump on a Fisker Ocean can manifest in several ways, with some symptoms being specific to the recalled cabin pump.
- Sudden Loss of Power and "Limp Mode": This is the most critical symptom associated with the recalled cabin water pump. The vehicle will suddenly slow to 10-20 mph.
- Dashboard Warning Lights: A "Battery Issue, Service Needed" message may appear, or other battery-related telltales might illuminate. Overheating warnings may also be displayed.
- Cooling Fans Run Constantly: A failing pump can cause the system to try and compensate by running the main cooling fans at high speed, even when the vehicle is off.
- Unusual Noises: A failing pump bearing or impeller can cause a whining, grinding, or buzzing sound from the area of the pump.
- Coolant Leaks: While less common than electronic failure, a pump's seals can fail, leading to visible puddles of coolant under the vehicle.
- No Cabin Heat: If the cabin heater pump fails, you will lose the ability to heat the interior of the vehicle.
Buying a Used Fisker Ocean Coolant Pump

Given the manufacturer's status, sourcing parts like coolant pumps can be difficult, making used OEM parts a viable option. Here’s what to check before you buy.
- Verify the Part Number: This is the most important step. Remove the original pump from your vehicle and find the OEM part number printed on its housing. Match it exactly to the used part you plan to purchase. The known part numbers are FM2930130028A, FM2930130029A, FM2930200022A, and FM2930200026A.
- Inspect the Electrical Connector: Check the pins inside the electrical connector. They should be straight, clean, and free of any green or white corrosion. Corroded pins indicate moisture intrusion, which is a major red flag.
- Check for Physical Damage: Carefully inspect the plastic housing for any cracks, especially around the mounting points and hose connections. A part from a collision-damaged vehicle could have hidden stress fractures.
- Look for Signs of Leaks: Examine the area where the pump's housing sections meet. Any chalky residue or staining could indicate a past leak from the main seal.
- Consider the Source: Whenever possible, purchase from a reputable seller who offers a warranty. Since the recalled pump (FM2930200022A) was updated with a better design, ask the seller if they know whether the used part is the original or the updated version. An updated version is preferable.
Pro Tip: For an electric vehicle like the Fisker Ocean, using a genuine used OEM pump is strongly recommended over any potential aftermarket options. The vehicle's complex software and thermal management systems are designed to work specifically with the flow rates and communication protocols of the factory pumps. An incompatible aftermarket part could fail to communicate correctly, potentially triggering limp mode or providing inadequate cooling.

Replacement Information
Replacing a coolant pump on the Fisker Ocean is a moderately difficult task. It requires removing underbody panels to access the pumps, draining the specific coolant loop you are working on, and carefully disconnecting hoses and electrical connectors. After installation, the coolant loop must be refilled and a procedure must be run to bleed any air out of the system.
🎬 See this professional walkthrough of the water pump serviceWarning: The Fisker Ocean is a high-voltage electric vehicle. Improper service procedures can result in severe injury or death. The high-voltage system must be properly de-energized before working on components like the electric coolant pumps. This repair should only be attempted by technicians familiar with high-voltage EV safety protocols.
Frequently Asked Questions (FAQ)
Can I drive my Fisker Ocean if the coolant pump is failing?
No. If you experience symptoms of a failing coolant pump, especially the sudden loss of power associated with the recalled cabin pump, it is not safe to drive. The vehicle can slow to 10-20 mph unexpectedly. Even for other pump failures, continuing to drive risks catastrophic damage to the high-voltage battery or drive motors due to overheating.
Is the coolant pump failure covered by a recall?
Yes, the failure of the cabin electric water pump is the subject of NHTSA recall 24V-499. 🎬 Watch: A detailed breakdown of the water pump recall The fix is a replacement of the pump. However, with Fisker's bankruptcy, getting this service performed free of charge may be difficult and depends on the availability of parts and authorized service providers.
Why does my car go into "limp mode" if the cabin heater pump fails?
The failure is not about a lack of heat, but about a loss of communication. The cabin pump's faulty electronics cause a communication breakdown on a data network that the high-voltage battery management system monitors. As a safety precaution, when the battery system loses communication with this component, it defaults to a protective limp mode to prevent potential damage.
What kind of coolant does the Fisker Ocean use?
The recommended coolant is a 50/50 pre-mixed Organic Acid Technology (OAT) type, such as Prestone Dexcool or ARTECO HAVOLINE XLC. Using the correct coolant is vital for protecting the internal components of the cooling system from corrosion.
