Front passenger door handle is stuck closed, should be fixed under recall(NHTSA Campaign Number: 24V466 Subject: Safety Recall Campaign TSB55062401 – Outer Door Handles (2023 and 2024 Model Years Fisker Ocean)), but have recieved no correspondence or reply from anyone about it. Passenger door has to be manually opened from inside vehicle since outer handle is not functional. Also, after software updates as per recall, the ADAS system gives all kinds of "lane departure failure", "collision warning failure" alarms that ding incesantly and cant be silenced. It is very annoying and distracting while driving to have blinking lights on the dash and warning buzzers.

The manufacturer was required by NHTSA to update the vehicle software to address critical safety issues. This effort was implemented through Over The Air (OTA) updates last fall. This software update was a very large and complex file and required the car to be "On" for the duration of the updates. This caused the 12 V battery to drain beyond capacity, and the update was only partial, resulting in a non-operating vehicle. In order to remedy this situation, a local technician was needed to manually install this update, resulting in an $800 charge directly to me for this mandatory recall. The technician was able to "unbrick" my car, as well as complete the software update to the NHTSA required software level of version 2.2. Even after this update, my car is unreliable, and has safety issues with warning lights in the dash. There were 3 critical recalles issues by the NHTSA for this vehicle - 1) Software update, 2), Door handle function, 3) Coolant pump replacement to avoid "limp mode" in the drive train. I have had all of these issues coompleted on my vehicle, with an out of pocket expense of $800, which has not been reimbursed by the trustee for this company. The company (Fisker) is in bankrucy proceedings (chaper 7), and all responsibilities to get these recalls accomplished and paid for, have not been accomplished. The OTA team, and the trustee are not cooperating with the owners of these vehicles. We are all stuck and need an intervention by the NHSTA to help get these recalls and reimbursements completed.

am writing to express my deep concerns regarding the ongoing issues that are being seen with the NHTSA recall campaign numbers 24V865000 and 24V623000. Specifically, the Advanced Driver Assistance System (ADAS) in my vehicle, which has become increasingly distracting and, frankly, dangerous due to an incomplete or failed 2.2 Over-The-Air (OTA) update is a huge concern. As a responsible driver, I value the safety of not only myself but also those around me, and this situation and others we constantly hear about make me question the process of the recall. Every week, a number of vehicles are reported as undrivable post-OTA updates, with statistics indicating that approximately 2%-5% of owners experience this issue. With 48-hour update windows, my vehicle becomes unusable for an extended period, which is highly inconvenient and concerning. Moreover, I've noted that partial updates are expected, potentially extending this downtime by another 48 hours. I have had a partial update that has left my vehicle in worse shape than before, what could happen if the process is tried again? This inconsistent performance is not only frustrating, but also poses a serious inconvenience to scheduling and executing such a process. Owner surveys suggest that comprehensive updates, which should resolve these issues, have been successfully completed in under 30% of vehicles which were attempted. Additionally, the alarming figures shared indicate that only around 10% of the fleet has been updated in over five weeks, despite submitting over 800 Vehicle Identification Numbers (VINs). This inefficiency raises serious questions about the reliability of the process. Furthermore, the fact that there are only approximately 20 service personnel available nationwide, with a mere five traveling to assist customers whose cars are rendered undrivable, is simply unacceptable. This lack of support exacerbates an already troubling situation.

My concern relates to the recall campaign for 24V623000 reduction in regenerative braking. The slow roll out of this campaign caused this unrepaired recall to result in a crash of the vehicle resulting in a complete loss. While driving on a highway in subzero temperatures, the driver let off the accelerator to slow the vehicle around a corner. At this point the vehicle lost the expected braking and began to lose control. This sent the vehicle to understeer and toward oncoming traffic. An attempt to correct sent the vehicle out of control and into a collision with barriers, spinning across the road with the rear door on the driver's side completely ripped from the body. While the driver was not hurt, it is quite possible that a passenger could have been thrown from the vehicle and seriously injured. This is an obvious serious safety risk to not only the occupants of the car, but such loss of control could have resulted in death or serious injury without emergency corrective action and frankly a little luck. It is particularly concerning that very few of these recalls have apparently been addressed. It has been shared that fewer than 10% of the public vehicles have had this issue addressed, months after the recall was announced. I feel that had this issue been addressed in a timely manner this incident would not have occurred and I fear for others that might find themselves in a similar perilous situation.

MY Ficker Ocean failed an over the air software update on [XXX]. The failure made my vehicle non drivable (could not shift out of Park). The car was parked in my garage for almost two months before a prior Fisker employee was able to look at it. Unfortunately they were not able to fix the software problem and requested I have the vehicle transported to an authorized service center 60 miles away. I paid $200 to have the vehicle flatbed transported to Riverside, CA service center where it sat for a week and could not be repaired. I paid $180 to have the vehicle flatbed transported to Newport Fisker in Costa Mesa where they were able to reinstall the proper software and make the car drivable. It cost me $1000 to have the software updated and the vehicle "unbricked". I picked up my now operational vehicle at the end of October and soon started receiving the bright orange ADAS failure message: 1) ADAS System Failure, Some features limited or unavailable 2) The red ADAS Tell-tale light also remains illuminated.

Recall 24V865000 24V623000 24V499000 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.I hope this message finds you well. I am writing to formally express my concerns regarding the OTA (Over-the-Air) update process for my vehicle. The current OTA process, lasting 48 hours, is simply not feasible for those of us who rely on our vehicles for daily activities. The inability to use my vehicle during this window forced me to pay out of pocket for alternative transportation, which is both inconvenient and financially burdensome. Additionally, it has come to my attention that there have been numerous reports from fellow owners indicating that a significant percentage of vehicles (approximately 2%-5%) have become undrivable following these updates. This situation is alarming and raises concerns about the reliability of the updates being delivered. Moreover, the lengthy windows of 48 hours for updates, coupled with the expectation of partial updates requiring additional time, have left many of us in a state of uncertainty regarding the functionality of our vehicles and forced to pay out of pocket for a mandatory free recall. According to owner surveys, it appears that complete updates—which include all necessary corrections—have been accomplished in less than 30% of cases. Furthermore, I was surprised to learn that only about 10% of the fleet (approximately 300 vehicles) had been updated after several weeks of attempts, despite over 800 VINs submitted for this process. Being that this is our only car I could not afford to wait for the OTA and its malfunctions. I was forced to pay out of pocket to a Former Fisker Tech to come to my house and manually install as well as have a new 12v battery installed costing me a total of $1,262.89. In addition I have not been able to have the water pump recall installed due to no supply and/or service. How is this legal?

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.

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.
