The Fisker Ocean was delivered with door handles that have major physical defects, including entrapment inside the vehicle in the case of 12V power loss and users unable to enter the vehicle. In my case, I have installed an emergency door hatch release myself in the trunk of the car to prevent entrapment. I have also ordered the new Gen2A door handles manufactured by Chevalier. These Gen2A door handles should have been provided free of charge to all Fisker Ocean owners if the company still existed. I believe we should be compensated for faulty and dangerous door handles. American Lease, the company now responsible for the fleet of Fisker Oceans, should pay for the handles and the repair cost. I have included the receipt of the door handles I had to purchase, but this does not include the labor cost to install them (at least $1,000). In addition, the Fisker Ocean was delivered with problematic rear reading lights that turn on randomly due to a faulty metal switch. This means the light can turn on when the car is parked and off, or even more dangerously, while driving (especially at night). I removed the switch. Finally, the Fisker Ocean was delivered with electrical wiring that was not properly waterproofed causing many, many errors for users. I have taken off the front and rear bumpers to properly waterproof these wirings, taking hours of my free time to protect connectors from water ingress. This is unacceptable for a car that was produced in 2023-2024.

There was an NHTSA-mandated water pump recall for this vehicle, and I had the pump replaced on March 16, at an out-of-pocket cost of $175. I have been told (by the Fisker Owners Association) that this cost is supposed to be reimbursed to me, but that there is currently no way for me to request that. Why not?

Difficulty getting recalls completed due to overcharging by Indigo and other entities. Have not gotten complete software update needed for the recall. Partial update has severly decreased range of car, making it much worse than what it was beforehand. Lots of errors popping up because of faulty update and faulty software before it, so many that I don't know what is true or not. So, may be missing true safety issues. Need to pay to replace water pumps myself because monies have not been freed up (this is part of another recall). Extreme difficulty getting service because of over charging for FAST tool needed for servicing.

I paid out of my own pocket for a safety recall, with no evidence I will ever be refunded, and the recall team has un-done my recall update. This is the 2.2 update that was put in place to fix the potential issues with the safety of the vehicle. I do not know what they have undone. I know that my system went from full 2.2 software to 2.2.2 (part2) of the update. I have no idea if they will now update the vehicle back to the safe 2.2 version, as there are zero plans, and the recall team is insisting that this partial update satisfies all the recalls. But the recall documents say 2.2, not a partial update.. god knows if it is even safe to sit in this incomplete configuration. Still no plans to get water pumps and door handles done yet either. I just started calling tech to travel to my area for these services. 10 of us are going to be paying out of pocet for these recalls as well.

I am writing to express my deep concerns regarding the ongoing issues that are being seen with the NHTSA recall campaign numbers 24V865000 and 24V623000. The experience I had with my Fisker vehicle following the 2.2 Over-the-Air (OTA) update attempt left my vehicle un-driveable from Jun 15 2024 through Oct 26 2024. This had left me in an inconvenient and frustrating situation. As a result, I had to incur additional expenses to have the necessary safety updates completed to restore my vehicle's functionality. This is far from the experience that I expected when signing up for a free mandated safety recall. While my vehicle was functioning fine after this manual update, on April 17th 2025 the OTA team pushed a software update 2.2.2 which seems to have regressed my car to some older version which has made it unstable again. It is draining battery much faster than before and my passenger side door handle won't extend anymore. This is going to require me to get these fixed at an additional cost. Moreover, I've noticed a concerning trend regarding the frequency of issues reported by fellow owners after OTA updates.I urge you to address these issues promptly, putting more vehicles in danger of becoming un-driveable because of the safety recall process being flawed may not be helpful in this current process. Additionally, I would appreciate any assistance you can offer in resolving my current situation and compensating for the expenses incurred due to this inconvenience. Thank you for your attention to this matter.

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.

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.
