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?

My vehicle has been undrivable for the past 4-5 months. It started when I was leaving my work's parking lot after removing the car from the chargepoint charging station. The vehicle suddenly started stalling and gaining power when I was accelerating then losing power afterwards. I readily parked in one of the spots, exited the vehicle, locked it and unlocked it after a few minutes in hopes that it would turn on and work normally. The car would turn on, I would put the vehicle into "D" and when accelerating, the vehicle would go into "N" automatically making me lose traction and the car going forward and scaring me to death as my car was on a spot in front of a valley. Thankfully I was able to press the break quickly and and turn on the "hand brake". Now the vehicle decided to work again, but I'm extremely scared this issue will happen again and I don't feel safe. There were other times that in city the auto brake activated (as if I hit a vehicle) with having no vehicles in front of me. Other times when the "Hold" breaking system would be engaged with the gentlest taps on the brake and then the car would just go into park even I wasn't parking the vehicle (both times when the car was in movement becoming a hazard if people behind me kept accelerating). Now I just received the SW update 2.2.2 in my car but I'm not confident my vehicle is fine. My HVAC vents don't work and I can't even have my cabin heated as I'm worried about the water pump going out. I haven't received any support regarding the recalls, nor any information on how to proceed, please, NHTSA, I need help

There were three times that after I had the car in park and tried to get out that I was unable to open the driver door to exit. The driver door out side handle did not automatically pop out to allow me to exit. I tried locking and unlocking the door internally and also tried with the car on and in park. On one occasion the window was stuck closed, probably because of icing. I ended up crawling over to the passenger side to get out. On the other occasions the door handle was popped out but I had to open the window and open the door using the outside handle. Frequently, the driver door handle won't go back in until after I have been driving for a few minutes. This seems to be the only handle with the issue of "sticking" either popped in or popped out. Occasionally when I lock it using the key fob, all the handles go in except the driver side. When I give it a little push from the outside it will go back in. At 2600 miles the NFC reader in the door handle stopped working. It is my understanding that the door handle recall was already performed on this vehicle. It is my belief that the vehicle is not better off after the recall. And that the $100 being offered to perform a door handle recall is far below the real world cost of such a service. Not to mention most techs can't get in and out of the door without leaving some damage to the panels or clips. I believe the recall on this vehicle for the door handles should not be considered completed. Or it should be reopened. There is also no emergency release strap anywhere in the vehicle for a door or window. Similar to the trunk manual pull from the inside. Please help us get this fixed. The ADAS warnings and chimes blinking lights etc are distracting as they are mainly warning for things we don't have working. Also the drivers screen flashes red to blue when changing fram accel to decel. Very distracting at night. Thank you.

PE24013 · 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.

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.
