Due to a faulty sensor in the driver seat, the car shifts into Park at random when at a red light. This is large triggered by the driver shifting their weight in the seat, which causes the vehicle to interpret that the driver has exited the vehicle. The door system will malfunction and lock the doors even when the key fob is in the vehicle when there is no one in the vehicle and all power is on. This forces the driver to enter through the trunk to then unlock the vehicle. Both are on going issues.

My car was bricked as a result of the OTA 2.2 update on [XXX]. This update was mandatory as it was what Fisker was doing to satisfy a recall. To try to remedy, I replaced the 12 v battery. I also followed online guides to get the High Voltage battery going again, as it was at 0%. I used a 25 amp and also a 40 amp 12 v charger attached to the battery, and this allowed the charge port to go to blue (from red) after 20 min attached to the 12 v charger. Once I attach the HV charger cable (I have tried both Level 1 and Level 2) the light blinks green as expected but then goes to red and fails after about 20 seconds. I finally got it fixed on [XXX] as the Fisker representatives were not able to resolve. I hired an ex-Fisker Tech, [XXX], based on guidance from the Fisker Facebook group, to come and resolve the issue. The cost of getting the car back up and going included: 12 v Battery $259.99 Schumacher Battery Starter/Engine Starter $164.99 [XXX] - Ex Fisker Tech travel from St Augustine $350 [XXX] - Ex Fisker Tech time and materials to resolve issue $1230 Total costs: $2004.98 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Fisker Inc has gone out of business. A mandatory recall has been issued and the bankruptcy court has assigned a trustee to ensure vehicles are updated to version 2.2 to address safety recall issues. The update to 2.2 has been extremly unpredictable and the trustee has not been able to complete this recall. Of the cars that were updated, mine, almost immediately the estimated range has been reduced drastically. The car was marketed as 360 miles range on 100% charge and now after the update I barely see 190-200 at 100% charge. This occured since the recall update. thats like 40-45% reduction in range costing everyone double the electricity needed to charge the vehicle and everyone I know that got the 2.2 update has been going through this issue. After running a diagnostic with a fisker tech, they mentioned it's a 2.2 update issue and no fix out there yet. However the trustee is responsible to roll this same update to other cars as well that hasn't received it. The tech explained this is occuring due to the rear motor is now throwing "flux error codes" and not functioning properly past 2.2 update which is causing the insane battery drain. In my opinion this is something that needs to be addressed. NHTSA recall campaign numbers for the software recalls are 24V865000 and 24V623000

I have all the outstanding issues out on this car and probably more. For example, sometimes the car's brakes will fail and the car can roll away. There are times when the car's regenerative braking is not working properly which decreases braking performance and can lead to a crash. Sometimes I notice that my car has a loss of power, which is concerning as it may cause an accident or worse. My water pump has not been replaced. To my knowledge, my door handles currently are not sticking, but this has not been looked at or addressed. I get constant warning lights alerting me to a safety system either not working or failing if that is even the case. I am still on software 2.0 and have been waiting patiently for the 2.2 update to address many of these issues, but have not been contacted at all from the OTA team to schedule one or been pushed one.

Vehicle needs software update to 2.2 NHTSA (Campaign Number: 24V405000) but there is no contact regarding when this will happen. The ADAS Warning system has had a warning light on since I received the vehicle. I had to disable audible warnings because they were distracting and dangerous. Also, the vehicle needs a replacement water pump (NHTSA Campaign Number: 24V499000) and measurement of door handles (NHTSA Campaign Number: 24V466000). I have not used the vehicle for long trips for fear of water pump breaking causing me to be stranded. Fisker trustee has not made the recalls noted above available to me as an owner. I've been locked out of my car twice for 30+ minutes. The anxiety of being able to get into the vehicle is unnerving and I can not take my dog with me and leave him in the car as I run errands for fear of not being able to unlock the vehicle when I return, as happened to be in March 2024 and April 2024. The Trustee needs to be forced to provide all owners with the agreed upon recalls before he is freed from the trustee duties. It has been months and there is no contact on how to get these updates. Please help.

My windshield was hit by a stone in April 2024, and I have still been unable to source a replacement windshield. My driver seat belt sensor went out and froze the rear brakes. I had to burn through the brake pads to get the car off the road, and had no rear brake pads until I was able to locate a salvage pair and new rotors to repair them, and a new seat sensor. The cost of this work and parts is $1,335.31. I had to pay to have the recalled water pump replaced. The cost of this was $325.

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. Multiple attempts of this safety recall have been scheduled over the past several weeks for my vehicle, but the update has yet to be completed. As an owner who values safety and reliability, I am increasingly concerned about the unresolved safety issues that were supposed to be addressed with this software update. To date, I have been disappointed to learn that each week brings reports from fellow vehicle owners indicating that their cars have become undrivable following these updates, with a concerning failure rate of approximately 2% to 5%. This is unacceptable for any customer who relies on their vehicle for daily transportation. Additionally, the lengthy 48-hour windows during which our cars become unusable only exacerbate the frustration and inconvenience faced by owners. The expectation of partial updates, followed by yet another potential 48-hour downtime, is not a practical solution. Furthermore, the feedback from owner surveys suggests that complete updates, which should ideally resolve these issues, have only succeeded in under 30% of attempted vehicles. This raises serious questions about the efficacy of the OTA update process and its implementation. I was also alarmed to learn that after five weeks of attempts, only about 10% of the fleet—approximately 300 vehicles—have been successfully updated, despite over 800 VINs submitted for these updates. The lack of service personnel, with only around 20 available nationwide and just five who can travel to address undriveable cars, only adds to the urgency of this matter. It is imperative that this process is reviewed and the underlying safety concerns that have left many of us feeling unsupported and frustrated are resolved in a manner that will be free of cost and successful to the majority of owners. Thank you for your attention to this matter.
My water pump was replaced as part of recall, however, i had to pay out of pocket for pump and labor. Iam unsure my ADAS and warning system is working and automatic breaking is working. This is so unreliable system and can't be trusted. Manufacturer had shown no effort on delivering the quality and safety.

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. To review the reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.
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.

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.
