There is a recall, 24V623 on my vehicle, Fisker Ocean, relating to the brakes and regenerative braking. The OTA software 2.2 update was supposed to fix this issue. I received the 2.2.2 update on February 23, 2025. Which I understand is not the complete update, still waiting for the last part to arrive (there is supposed to be three parts to this update.) Receiving this update introduced new problems with the vehicle. Others in the Fisker Owners Association group has reported the same issues. Namely that the drivers display and the center screen failed to start when the car is started or if the displays do start they can blank out while driving. These issues started after I received the OTA software update. The issue was infrequent at first and now it happens almost every time I start the car. With the center screen being blanked out there is no way to control any of the many essential functions of the car. It affects the regenerative braking, ADAS functions such as lane keep assist and warnings, charging settings, HVAC functions, no heating/cooling or defrost and a few other functions too. When the drivers display is blank, I can not see the speed of the vehicle or what gear or mode I am in.

I am a Fisker Ocean One owner and was able to schedule time with EV Works in Bainbridge, WA for replacement of parts related to NHTSA recalls. They were great to work with and were able to complete the replacements as expected. They replace the Water Pump (24V499000) and all four Door Handles that failed the testing (24V466000). All parts were provided at no cost. However, I was required to pay out of pocket for all labor related to this mandatory free recall: $1019.28. Two other issues were looked at as part of my visit to EV Works. They inspected and waterproofed electrical connectors in the front passenger side bumper. Fisker failed to adequately protect these as part of the vehicle assembly and they are known to get water intrusion and fail. This cost out of pocket $71.60. Part of why EV Works was looking at the electrical connections is because I have an ADAS Radar Fault warning. They determined this is caused by failure of both front mid range radar components. which leaves the vehicle with no Blind Spot Monitoring. I have heard of several other owners online reporting a similar issue with their cars. I expect this is due to low quality parts used in assembly and that more cars will start to get this warning and lose the ADAS feature. EV Works quoted this replacement as $980.97 but I have not completed the repair yet. This should have been covered by Fisker warranty.

There are multiple outstanding Recalls for the Fisker Ocean, yet my VIN returned no active Recalls even though it recognized my car. This doesn't make much sense to me. There are currently at least two critical safety issues that reached recall status, related to the Driver's Door Handle and the Electric Water Pump. Reimbursement is required by both the NHTSA and bankruptcy court and the court designated that American Lease was responsible for processing and paying those reimbursements. I need to have both the door handle and water pump recalls performed by a FISKER (FOA) approved servicing center, for the sake of my safety and the safety of others on the road when I drive my vehicle. There is currently no process by which receipts can be submitted and payments received, or for service providers to be reimbursed directly by American Lease. This violates both the court's order as well as NHTSA regulations and laws. This is going to leave me out nearly $1000, which I am, legally, not supposed to be paying, just to keep my car in somewhat safe condition for driving. Please address this so that those who purchased and acted in good faith have reimbursement as required by law. Thank you.

An OTA update got pushed to my car without warning, and for over a month the infotainment screen (which has all info on car, controls, etc) was not working. Car did drive, though. Then, last week, the infotainment panel started working by itself again, but car functions such as lane assist / automatic nudge, collision avoidance function, and auto emergency braking stopped working (to be fair, they may have stopped when the screen went blank initially, but I wasn't paying too much attention and I didn't drive the car very much). There is no fault code or warning. These systems just don't work. Interestingly, the lane departure warning (a light that goes on if there is a car in your blind spot) started working, and it never has before.

More bugs and problems after partial OTA to version 2.2.2 than before. Constant alarms and warnings that ADAS is not functioning. Driver alert monitor stopped the car in the middle of the road because it said I was not paying attention. The biggest problem is the car no longer detects the key FOB inside the car. New battery and I can unlock the car from 100+ft away. But once in the car I'm forced to hold it to the NFC. One time I started the car, jumped out to grab something from inside the house, left my key there, then drove off. With no key in the car I was able to dive about 3 miles to the store. Somehow I was able to put it back into D and get home without it shutting down and asking to hold the FOB to the NFC again. The other safety related issue is the small driver screen will not dim. No matter where I have the brightness setting manually set or on auto the screen is always at 100% At night it is very bright and is not at all pleasant to drive with. I have started putting a piece of thin masking tape over it to dim at night. I can still see mostly see things that pop up.

Description of Incident(s) On March 5, 2025, I discovered that my 2023 Fisker Ocean had undergone an unauthorized over-the-air (OTA) software update to version 2.2.2 without my knowledge or consent. I received no prior notification from Fisker or American Leasing, the current entity managing Fisker vehicles following the company’s bankruptcy in 2024. Additionally, I have no access to the vehicle’s cloud system or update logs to understand what changes were implemented, leaving me unable to assess the scope or purpose of the update. Following this update, I experienced two significant safety-related issues with my vehicle, detailed below. Driver’s Door Handle Overheating After the 2.2.2 update, the driver’s side door handle began exhibiting extreme overheating, reaching temperatures exceeding 130°F as measured with a non-contact infrared thermometer. This poses a serious burn hazard and makes the handle unsafe to touch for entry or exit. The issue appears to be electrical in nature, potentially related to a malfunction in the door handle actuator or power management system altered by the software update. The handle remains excessively hot even when the vehicle is powered off, suggesting a persistent fault. This defect compromises safe access to the vehicle and presents a risk of injury. Rearview Mirror Fan Constantly Running Since the update, the fan associated with the vehicle’s digital rearview mirror now runs continuously, regardless of whether the mirror is in use or the vehicle’s thermal conditions warrant cooling. This creates unnecessary noise, potential wear on the fan component, and a possible drain on the vehicle’s battery. While the digital mirror functionality remains operational, the constant fan operation suggests a software glitch affecting thermal regulation or sensor feedback loops, likely introduced by the 2.2.2 update. This issue, while not immediately hazardous, indicates broader concerns with the stability of the vehicle’s software systems post-

4PE24013 · Inadvertent Automatic Emergency Braking
Opened May 8, 2024 · Closed Jan 16, 2025
Status: closed (inferred from source dates) · Forward Collision Avoidance: Automatic Emergency Braking
On May 8, 2024, the Office of Defects Investigation (ODI) opened PE24013 to investigate reports of inadvertent activation of the automatic emergency braking (AEB) system in model year (MY) 2023 Fisker Ocean vehicles manufactured by Fisker Group Inc. (Fisker). The complaints allege the activation of AEB without an apparent roadway obstruction in the vehicle’s forward path, resulting in sudden vehicle deceleration. This sudden deceleration occurs without adequate warning or input from the driver. The braking applications range from momentary, partial application resulting in rapid loss of speed to full application, which brings the vehicle to a complete stop in the travel lane. ODI sent Fisker an Information Request (IR) letter on May 20, 2024. On June 17 and 19, 2024, Fisker and its affiliates filed a voluntary petition for relief under chapter 11 of the Bankruptcy Code. Fisker provided an incomplete response to the IR on July 1, 2024. Limited information pertaining to system validation and failure data was provided. Fisker subsequently requested more time to provide additional responsive files due to limited available resources. Fisker sent additional responsive files on September 9, 2024, September 17, 2024, and December 16, 2024, but Fisker’s response did not contain sufficient information for ODI to fully evaluate the alleged safety defect. Further, on December 27, 2024, the Fisker employees with whom ODI had been corresponding informed ODI that all Fisker employees were being “dismissed” as of that date. ODI therefore does not anticipate receiving any further responsive submissions such that it can fully evaluate the reports that led to this investigation. ODI performed phone interviews and sent a survey to consumers to obtain more information and validate the allegations. Additionally, ODI reviewed allegations of the alleged safety defect that were submitted to various online forums. Most of these reports were similar in nature to the reports received by ODI. Some of the reports in online forums appear to be duplicative reports that were also submitted to ODI. Based on the responses received and analysis of similar online reporting, there was no clear trend in the following factors pertaining to the allegations: reoccurrence of events (i.e., single or multiple incidents), speed immediately prior to the event, whether the event concluded in a reduction of speed or a full stop, roadway conditions, and warning immediately prior to the event. To date, between the reports provided by Fisker and complaints made directly to the agency, ODI is aware of over 20 reports alleging inadvertent AEB activation. Before the employees were dismissed, Fisker’s testing done in response to the inadvertent AEB allegations reportedly did not result in any inadvertent AEB activations. The “Manufacturer” and “Total” counts in the above table have been left blank because of a pending request for confidential treatment by Fisker that could not be timely addressed given the company’s status. This information factored into ODI’s investigation and analysis. The available information does not warrant further action at this time. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. Additionally, the Agency notes that the Vehicle Safety Act states: “A manufacturer’s filing of a petition in bankruptcy under chapter 7 or chapter 11 of title 11 does not negate the manufacturer’s duty to comply with section 30112 or sections 30115 through 30120 of this title,” which include the recall provisions of the Act. The Agency reserves the right to take additional action if warranted by future circumstances.

PE24010 · Failure To Open Door
Opened Apr 1, 2024 · Closed Aug 26, 2024
Status: closed (inferred from source dates) · Latches/locks/linkages:doors:latch
On April 1, 2024, the Office of Defects Investigation (ODI) opened PE24010 to investigate instances of failure to open the door in model year (MY) 2023 Fisker Ocean vehicles manufactured by Fisker Group Inc. Some complaints allege the inability to open the door from either the interior or exterior door handle, resulting in the need to use another door to egress. The investigation revealed that all four exterior door handles are subject to sticking in the extended/unlocked position, which may result in the inability to unlatch the door from either the interior or exterior door handle. The root cause is a dimensional interference between the exterior door handle chassis pocket and door handle, causing friction during handle deployment and retraction. The inability to open and egress from the occupant’s adjacent door presents an unreasonable risk to motor vehicle safety. On June 27, 2024, Fisker filed recall 24V-466 for certain MY 2023 Fisker Ocean vehicles. The recall remedy includes an inspection procedure for all four doors and provides replacement of the outer door handle if a “Not Okay” result is found. In view of the recall action being taken by Fisker, ODI is closing this Preliminary Evaluation. The agency reserves the right to take additional action if warranted by future circumstances.

PE24005 · Unintended Vehicle Movement
Opened Feb 14, 2024 · Closed Dec 6, 2024
Status: closed (inferred from source dates) · Power Train:automatic Transmission
On February 14, 2024, the Office of Defects Investigation (ODI) opened PE24005 to investigate reports of unintended vehicle movement in model year (MY) 2023 Fisker Ocean vehicles manufactured by Fisker Group Inc. The complaints allege the inability to shift into the park gear and/or vehicle rollaway. The investigation found that the subject vehicles contain a logic that prevents the engagement of the park gear when the park gear request is made while the vehicle is still moving at low speeds. In the event the driver requests the park gear prior to the vehicle achieving a complete standstill status, the vehicle rejects the park gear request, displays a visual warning, and shifts into the neutral gear. Therefore, if the driver does not properly restrain the vehicle prior to exiting (i.e., allow the vehicle to come to a complete stop, then provide a second park gear request and/or engage the parking brake), the vehicle is at risk of freely rolling away in neutral. ODI found that existing strategies to deter drivers from exiting the vehicle after failing to ensure the transmission successfully engages the park gear have not stopped some from doing so. The absence of additional mechanisms to mitigate the effects of driver behavior in failing to ensure the park gear was engaged prior to exiting the vehicle constitutes a defect presenting a risk to motor vehicle safety. ODI is aware of one reported injury due to this safety defect. On November 15, 2024, Fisker filed recall 24V-865 for all MY 2023-2024 Fisker Ocean vehicles. The recall remedy is the release of software upgrade OS 2.0. This software update provides additional robustness to prevent unintended vehicle movement via two major changes. First, in the event the driver seatbelt is unlatched when the vehicle is traveling at low speeds, logic was added to initiate an automatic, controlled deceleration to bring the vehicle to a standstill. Once standstill status is achieved, the vehicle will automatically engage the park gear and the electronic parking brake. Second, OS 2.0 introduced an “Auto Vehicle Hold” feature, which holds the vehicle in standstill by maintaining friction brake pressure when the driver removes their foot from the brake pedal. This feature prevents the vehicle from rolling under gravity, which therefore helps engage both the park gear and electronic parking brake. In view of the recall action being taken by Fisker, ODI is closing this Preliminary Evaluation. The agency reserves the right to take additional action if warranted by future circumstances. To review the reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.
PE24001 · Loss Of Braking Performance
Opened Jan 11, 2024 · Closed Aug 26, 2024
Status: closed (inferred from source dates) · Service Brakes; Service Brakes, Electric:software/programming
On January 11, 2024, the Office of Defects Investigation (ODI) opened PE24001 to investigate instances of loss of braking performance in model year (MY) 2023 Fisker Ocean vehicles manufactured by Fisker Group Inc. The complaints allege an intermittent partial loss of regenerative braking over low traction surfaces, without alerting the driver. ODI is aware of six minor crashes and one injury due to this failure. The subject vehicles utilize a brake blending feature to achieve deceleration. Upon application of the brake pedal, both the service brake system (friction braking) and regenerative braking system (electric motor negative torque) are applied. Regenerative braking on low friction road surfaces may result in wheel slippage due to the high motor negative torque. The vehicle responds by reducing and/or eliminating regenerative braking torque to reduce wheel slip on drive wheels to maintain vehicle stability and steerability. This reduction in regenerative braking may cause a sensation of loss of braking force (or even vehicle accelerating) that was reported by consumers. Additionally, the driver may experience an unusual/altered brake pedal feel during loss of regenerative braking events, requiring them to press the brake pedal harder to maintain the expected braking rate. Upon exiting the low friction road surface, the regenerative braking force is restored. The initial calibration of the regenerative braking system contained aggressive interventions with a slower recovery in the event of loss of regenerative braking. In November 2023, Fisker launched an Over-the-Air update (OS1.10 SW). This update included a recalibration to reduce regenerative braking torque less aggressively and allow torque recovery to occur more quickly. Based on consumer reports and the data that Fisker provided in response to ODI’s inquiry, OS 1.10 SW reduced, but did not eliminate, the sensation of loss of braking force and resulted in stopping distance performance improvements. Friction braking is always available when the driver presses the brake pedal, and its performance is unaffected by regenerative brake loss. Fisker’s braking system is designed to reach full deceleration even with an unavailable regenerative braking system. The partial loss of braking force during moderate braking events can be overcome by applying additional pressure to the brake pedal to slow or stop the vehicle. On August 20, 2024, Fisker filed recall 24V-623 for all 2023 MY Fisker Ocean vehicles produced for the U.S.A. The recall remedy includes OS 2.2 over-the-air update, which is expected to modify the brake module to enhance the vehicle brake system’s ability to adapt to various driving scenarios. With successful implementation of OS 2.2, a road disturbance will not trigger a reduction in regenerative braking torque. In view of the recall action being taken by Fisker, ODI is closing this Preliminary Evaluation. The agency reserves the right to take additional action if warranted by future circumstances. To review the reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.

Based on consumer reports and the data that Fisker provided in response to ODI’s inquiry, OS 1.10 SW reduced, but did not eliminate, the sensation of loss of braking force and resulted in stopping distance performance improvements. Friction braking is always available when the driver presses the brake pedal, and its performance is unaffected by regenerative brake loss. Fisker’s braking system is designed to reach full deceleration even with an unavailable regenerative braking system. The partial loss of braking force during moderate braking events can be overcome by applying additional pressure to the brake pedal to slow or stop the vehicle. On August 20, 2024, Fisker filed recall 24V-623 for all 2023 MY Fisker Ocean vehicles produced for the U.S.A. The recall remedy includes OS 2.2 over-the-air update, which is expected to modify the brake module to enhance the vehicle brake system’s ability to adapt to various driving scenarios. With successful implementation of OS 2.2, a road disturbance will not trigger a reduction in regenerative braking torque. In view of the recall action being taken by Fisker, ODI is closing this Preliminary Evaluation. The agency reserves the right to take additional action if warranted by future circumstances.
