I scheduled a OTA update as recommended in the recall campaigns. I was given a 48 hour window where I was unable to use the car and must keep it charged at all times. After completion I saw that the entire update was not completed. And about a week later another update came where I was not notified or scheduled at all for it. I returned to a car with a dead battery. Upon jumping the car had numerous errors and alert signs all over the display screen. ADAS was now detecting non existend obstructions in all directions and was throwing alerts constantly while driving. One two separate occassions both the drives and passenger side doors would not unlock and we had to exit via the rear doors. On another 2 incidents there was no interior lighting at night and I was unable to see the buttons to adjust my mirrors, unlock the doors, or even turn on the headlights at night. The Rear camera stopped working completely and to this day it has no signal which makes it difficult to reverse this car as the rear window is so high and small. And the remaining cameras are all failing intermittently. Furthermore the brakes have been jumpy, with some instances where the brakes did not deploy immediately but felt delayed. NHTSA recall campaign numbers are below: 24V865000 (Roll away OTA-2.0) 24V865000 (Regen Braking OTA-2.2) 24V499000 (Water pump) 24V466000 (Door Handles) 24V405000 (Warning Lights OTA-2.1) 24V404000 (MCU/VCU Loss of Power OTA-2.1

My car was scheduled the first week of the updates. The car would not update. Afterward, the batter drain was very noticeable. Now there is no internet service for the car... not from Fisker and while I can verify it connects to my home wifi and mobile phone hotspot, it will not allow data to the car. I took this to a dealer to have the water pump replaced, the car updated, the 12v batter replaced, the t-box reset and the door handle inserts replaced. They were unable to repair the drivers door handle (the LED lights actually generate smoke) and I cannot use the NFC to enter the car. Additionally, one day while charging the vehicle, all of the door handles retracted when I closed the door and the key was in the car. Thankfully the rear hatch was not locked because my DOG WAS INSIDE! This car is dangerous and no one is helping!

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-

I was scheduled for the 2.2 update (to fix various recalls) on 11/11/24, with a healthy 12V battery, connected to a tender. I left the car alone for 3 days, to be sure that there was plenty of time for the update to be pushed. When I went to drive the car on [XXX], the car would not drive. It showed to be in "N" (neutral), would not shift to park or drive, every warning light possible was lit on the dash, and the "pedestrian warning" hum was sounding. Even exiting the vehicle and locking it did not turn off the infotainment center. I was unable to move or drive the vehicle in this state, and there are NO mechanics in Arizona with a FAST tool, to diagnose or fix the car. I had a former Fisker Master Technician come change the 12V battery (which cost $305.40 for the battery, and $150 for the install), but this did not reverse the above situation. Because it was "bricked", I couldn't even charge the HV battery to keep the 12V charged, so I had to hook up a 15A maintainer to the 12V, so that the car wouldn't drain the brand new 12V. The tech also tried disconnecting the HV battery, and reconnecting it, in hopes that it would reset, but it didn't. With no FAST tools available in my state, I ultimately had to sell the vehicle at a loss of about $70,000. When the new owner tried to have it towed, the front wheels were locked, despite the car showing it was in "N" (neutral), and it had to be dragged out of the garage, and then died (12V, now no longer on a maintainer) in the street, waiting for a tow truck that could haul it with the locked front wheels. I was never able to drive it after the attempted 2.2 update, so never got the recall work completed. I was also never able to get the water pump recall done, either.

My 2023 Fisker Ocean One (VIN [XXX] ) was in the first cohort of cars to receive the Ocean OS 2.2 update during the 24 hour period starting on [XXX]. The update seemed to have completed successfully, but six days afterwards on [XXX], I stopped for lunch after driving a few errands that morning, and afterwards I came out to my car, opened it, then stepped on the brake pedal to start up the car -- upon doing so, I noticed that the three screens in the car that control its operation -- the driver's display (above steering column), the 17" infotainment display, and the HVAC "button bar" control display were all black (not illuminated) despite the car being powered on. In this state, the car could not be shifted out of park into drive. All of the other lights in the car that should have illuminated were illuminated, so I know the car had power, and I had charged up the high voltage battery to 80% SOC the night before. I tried several times over the course of the next few hours to get the car to work, but each time, the three screens in the car remained black and not showing anything. In the end, I had the car towed back to my home, so at least I could charge the high voltage battery and put the 12v battery on a tender (as required). From this first incident of "black screens on startup" on [XXX], each day afterward, I would test the car to see if it would start up correctly -- on some days it would start up with all 3 displays booting up into a functional state, on other days, I would again experience the "black screens at startup" and would be unable to drive the car. Only the Carplay screen I added to the car would be illuminated (shown in photo attached). I contacted Fisker-trained technicians who diagnosed the ICC as having been compromised during the OTA update. I found a salvaged ICC from another Ocean on eBay, purchased it, then paid to have it installed into my car and programmed to match it to my VIN number.

Unannounced, on February 12, 2025 update 2.1 was pushed to my automobile. It has amplified the already missing and malfunctioning safety features of the car. I started to receive 12v battery warnings, downhill traction warning light, sporadic ADA system failure warnings including: loss of lane departure warning and avoidance, loss of emergency braking capability, and loss of forward collision warning. The HVAC system is also malfunctioning - fan speed at start up is automatically high temperature and occasional sudden fogging of window interiors at highway speeds. The mileage remaining calculation also suddenly dropped, causing concern I would not make it home from work safely. I'm very afraid to continue driving the car: I worry it is a danger for myself and others on the road. I have been forced to take it to a service & repair center for an inspection to address the sudden low 12v power drop. I was told by the repair shop that there are outstanding safety recalls for the Fisker Ocean - why did none appear on this web page when I entered my VIN?

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.

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.
