The regenerative braking doesn't work when I hit a bump. There is a bump that can't be avoided in my route to my house. Every single time, without fail, when I hit that bump my regenerative braking goes out and more stopping time is required for me. This is especially dangerous because this bump is near a traffic light. If I have to slam on my brakes to avoid running a light (which has happened a few times) I have very little stopping time available and have nearly rear-ended and/or ran a traffic light on accident due to this failure of the brakes. Additionally, when this happens and I press the brakes to help slow me down there is a "hiccup" feeling where it feels like neither the regenerative nor even the normal braking is working. This lasts for about 1.5 seconds.

Fisker’s long-awaited 2.0 software update failed to correct the frequent failures of emergency braking and regenerative braking (ADAS features such as lane keep assist, blind spot monitoring, forward facing camera are also regularly malfunctioning) two new problems presented themselves; the car will throw itself into park apparently when it registers a traffic light shift from red to green (as I have been waiting at a light all 4 times this has happened it puts me in danger of rear end collisions) and the downward motion of the brake in one instance was limited to about 1/2” meaning all braking I did was done in short quick choppy bursts. The pedal felt like it was pressing down on something stuck beneath it (there wasn’t anything there.) For this reason I have filed Lemon Law paperwork with an attorney in CA, a Better business Bureau complaint in CA and have leased a new car because I no longer feel safe driving the Fisker ocean one. The problems all appear to be software related, the company no longer responds to service requests and they have already attempted fixes on the car four separate times in the 5 months I’ve owned it.

My Fisker has had multiple issues from the beginning. Seat sensor does not allow you to shift the car into drive or reverse. I had to shake my butt to get it into gear. There are at times that when I drive it goes into park for no reason. When it comes to braking it does this skip feeling which is very alarming. ADA notifications are constantly alerting (pretty much daily) where Auto Emergency Braking, Blind Spot warning, Forward Collision Warning are not working on a daily basis, especially in rain and when the sun rises and sets - it is a constant distraction. So n a nutshell here are the major issues: - ADA alerts constantly - When braking there is skipping (not all the time but more so when you really have to quickly brake - Seat sensor in the seat - must shake your butt to get it into gear due to it not being in the right place perhaps? (it's been serviced twice) - Skipping while braking hard -Fob key lags a lot, I believe it's a safety issue that you can't get in your car when needed especially in areas that are not so nice and as a female you should not be scared if your car will open or not - Not a safety issue but I do want to point out my vents turn on high and hot every time I get in the vehicle and need to turn it off

I am writing to advise you that I have been experiencing a failure with my regen braking system. This all started since I first got the Fisker, and I did not originally report it due to believing it was a temporary software issue that would be fixed with 2.0. Unfortunately now that I have 2.0, I still experience this issue. The problem that occurs is when I remove my foot from the accelerator, the regen braking engages, and I naturally assume the distance needed to come to a stop. The failure starts if you hit a bump or uneven pavement while the regen is in the middle of slowing you down. This causes the regen to disengage, and you experience the feeling of the car suddenly launching forward. This forces you to apply the brakes, which automatically causes the ABS to engage (which is something else that is unexpected). This experience has been both frightening and dangerous every time it’s happened. I have nearly collided into the backend of cars in front of me due to this failure. This causes high anxiety when I drive, especially because I don’t know when it will happen again, as it is a sporadic issue requiring the specific scenario for it to happen. It’s difficult to replicate, but it has happened numerous times to me. Thank you for your attention to this issue. (I have submitted this same information to Fisker as well)

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.
