We had issues with the car from the day it arrived ranging from the key fob not working to multiple warning lights that interrupted the regenerative braking. Despite multiple tickets filed, Fisker was unresponsive. After about two weeks of owning the car (less than 250 miles on a brand new vehicle), the car went unresponsive while driving despite having a full charge and no warning/issue alerts. The car shifted itself into neutral and when the driver tried to put the car in park to get out of the car and see what was wrong, the car started to roll forward despite being in park. To stop the car from hitting oncoming traffic, the driver was able to get back in the car and manually depress the brake. Once the driver hit the brakes, the car stopped rolling forward, however the car remained unresponsive to any of the other gears. To get out of the street, the driver used the momentum of the roll forward to try to make a slight turn back into the neighborhood street however ran out of momentum and got stuck in the middle of the street again with the car now rolling backwards. The driver hit the brakes again to prevent the rollback and because the car was unresponsive, the driver was stuck holding the brake from 7:21 AM to around 8:45 AM. At 7:37 AM the car went black and many of the controls started to glitch (we have videos but the uploader tool is limited to photos only) Due to the car now being completely blacked out, the brake is very heavy and the slightest movement will cause a rollback. After several attempts to get ahold of Fisker including their roadside assistance and live chat, the driver was unable to get help and called the police instead. The car had to be towed and has been out of commission ever since. A Fisker technician has tried to diagnose the issues after three attempts but things are still unresolved. Fisker remains unresponsive and hasn’t even provided us with documentation of the service diagnostics despite repeated requests.

When using the "regenerative" braking function by taking foot off the accelerator, if the car encounters minimal uneveness in the roadway (ie bumps, cracks, potholes, uneven surface etc) the "regen" function terminates without any warning and the car "free-rolls" until I am able to apply pressure to the brake pedal. When it does this, the vehicle feels like it is accelerating, but I realize it is really just gaining momentum that if not quickly reacted to could lead to loss of control during turns and at intersections or crosswalks. I have had this action happen no less than 10 times in my limited ownership time, and I thought it was going to be addressed during an OTA update, but it is still occuring.

The car has now on at least 6 occasions started to shake and rapidly decelerate after I pressed the brake to slow down or make a turn. The car dashboard then starts flashing the following warning signs: 1. "Brake system malfunction service required"; 2) "ASAS fault- Features Limited or unavailable. Drive Carefully"; and 3) "Battery Level low." Please charge battery now." The vehicle's steering wheel then starts to shake and the car then comes to a complete stop and shuts down. This has happened several times on crowded roadways putting me at risk of being rear-ended. The deceleration is very rapid and without any warning. I have a video of the car doing this and can send to you. Please note that the warnings on the dash appear to be inaccurate because each time this has happened the battery level has been sufficiently charged (making the "Battery Level low" warning completely non-sensical." I have reported this issue three times to the manufacturer Fisker. Once when I called for road-side assistance. On that occasion a company representative walked me through a reboot of the vehicle. I was hoping this would solve the problem but it didn't. The car has since done same thing about 5 to 6 times. I have sent Fisker two emails alerting them to the safety issue. The first emails was sent on January 10th and the second on January 15. In the second email I included a video of one of the above-referenced occurrences. In response to my emails Fisker assigned me two case numbers and promised to respond within 1-3 business days. To date I have received no response. I will not drive the car at this point for fear for my safety.

Firstly I think I must inform you that I am reporting this from the UK, I am a US citizen but live part time in the UK and this was a UK delivered car. I have also reported this to the UK DVSA. This is to report two problems that I think you should know about, both of which are potentially life threatening. 1.My wife became locked in the car and could only exit after the computer was rebooted. There is an electrically activated "Dead Bolt" that prevents the door handle from opening the door, this is under the control of the computer. If the computer system has a glitch, which it seems to have every time the car is driven, then the "Dead Bolt" may not release trapping one in the car. It seems ridiculous that this design has passed even a basic safety review. There should be a purely mechanical connection between the inside door handle and the lock, or a secondary emergency release handle. Imagine being trapped in the car after an accident with possibly a fire or the car filling with water and being unable open the door. There are many other reports of people being trapped in this model car on the Fisker forums etc. The Fisker UK sales manager told me of an incident where all 4 passengers were locked in the car for hours before a Fisker technician released them. I have returned the car to Fisker and have just received my money back, after telling them I would not drive the car again because of this potential safety issue. I think these cars should be taken off the road until the door locks are redesigned and retrofitted to every car. Someone is going to die trapped in one of these cars. Please take this very seriously, it reminds me of the Apollo 1 Catastrophe. 2. On three occasions while braking the brakes seemed to release while I was still pressing the pedal, the car even seemed to accelerate briefly which was very scary. On the third occasion I was stopping behind another car that stopped suddenly and I nearly ran into the back of it.

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.

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.
