Many grievances that are not addressed by the company: Brakes sometimes cause the car to "jump" forward and glide forward a couple of feet. If someone cuts you off and you have to quickly brake, the car may "jump" forward and get into an accident. The car has evidence of water build up somewhere inside the skeleton/body/frame of the car (evidence by "swishing" noises upon normal uphill acceleration, downhill deceleration, acceleration in general). Along with this, there's more evidence of water accumulation with visible condensation found on the windows that are from the inside (especially evident on the passenger side front and rear windows). There is a smell to the inside that is of standing water (humid smell). Concerned with mold if not addressed. The consul will stop working and either freeze or shut off altogether (in these cases no buttons can control the vent or audio systems). Occasionally the car will have the heater on, blasting hot hair and since the consul won't work, nor the buttons, there's no way to control that (at the same time, there's no way to control the audio volume either). The car's safety features are practically always inactive and the car prompts me to "drive carefully" based on this finding. "Lane assist" and "automatic brake" are the most frequently 'unavailable' safety features (daily). Car being stranded and unable to open or turn on multiple times. All this has been emailed to Fisker multiple times (with photos) and an automatic email response received that they will "review my concerns and respond within 48-72 hours" (that hasn't happened, no response). I've spoken to customer service (early March), expressing these issues verbally, being promised that a they will arrange for a "technician" to come out and review the issues to see if they can solve them or refer out to a physical location for the car to be evaluated if they can't solve. NO technician has been sent out and NONE of these issues/concerns have been addressed.

There have been many issues with my Fisker..Since the first day I got it I have had problems trying to get the car doors to open. I have even been TRAPPED MULTIPLE TIMES IN THE CAR unable to get out because the doors won't unlock to let me OUT. Since the first day I got the car I have been sending messages to fisker. Also, The first day I got the car, The Brakes system malfunction warning comes on often and the fisker IT Guys say” don’t worry about it “. The fisker support does not respond for days and sometimes weeks and sometimes not at all. Also I got the Fisker IT Service support technician for my are so I just text him most times with the issues. The AIr condition just stops working randomly. The sensors has been replaced but it keeps failing, the vents had to be replaced also and still have “bugs”. The doors not letting me out of the car are a HUGE safety risk for me and my family as well as not being able to get in the car. The Fisker technician has been to my house on several occasions and stayed for hours and then when he leaves I have the same issues. There are multiple incident dates as these issues are recurring. The brake malfunction while in driving started from day one I have a video. I also have text messages to the Fisker technician and one of the Fisker manager Sean O’Grady. i tried to load the video I have of the Brake system malfunction warning coming on as I am driving the car, but I couldn't get it to attach the file. You can email or call me if you need to get this.

Vehicle loses power/loss of throttle/loss of the accelerator. The first time this happened I was unaware and stuck in the middle of a turning lane when it lost power to the accelerator, after a couple of minutes the vehicle responded and because I was pressing on the pedal it kicked into full power mode sending me over a median into oncoming traffic. This situation not only put me and my child at risk it also put others. The same problem has happened multiple times I know better than to step on the pedal and not to panic. I spoke to my assigned Fisker technician, who stated it is a known problem. They have updated my software twice when was supposed to fix it but it has not. No warning lights or anything would warn anyone of this issue and Fisker claims nothing is unsafe. I also have a passenger door that doesn't always open. It has been fixed 4 times and still has the same problem. Again, Fisker states this is not unsafe.

I have had a recurring issue where the vehicle lunges forward when going over a speed bump, pothole or any rough spots on the roadway even when pressing on the brake pedal. It appears that the regenerative braking temporarily fails as does the standard brake in this occurrence, making the vehicle feel out of control and unsafe. Fisker announced that this was addressed with software version 1.10 but I have been on version 1.11 ever since receiving my vehicle a couple months ago and continue to experience this event. It most recently occurred yesterday while driving to and from the airport, going over a speed bump. Additionally, I continue to get "ADAS fault - features limited or unavailable" warnings and "Auto emergency braking unavailable" warnings and "Brake system malfunction - Service required" warnings on a regular basis for which I have numerous photos and videos. Also, on occasion I have had "Regenerative braking unavailable" warnings appear at which time the regenerative brakes are not functional, putting additional strain on the regular brakes.

My Fisker Ocean One has experienced multiple ADAS issues including lane departure not working, emergency braking failing regularly producing multiple warning lights, regenerative braking shutting off causing the vehicle to speed up or roll away. I have dozens of photos of the errors and videos. I will provide the link to the photo folder. The technician was finally able to update all of the vehicle modules to 2.0 to try to resolve this. That included a hold function updated. At roughly [XXX] I was pulling into my driveway. My road is a steep downhill to my house then a left into the drive. As I was slowly pulling into the driveway the vehicle jerked violently many times as if it was trying to stop but couldn't. I was not applying the brakes, but letting off the accelerator for the regenerative function to slow the car. When the jerking occurred I tried to brake and the brake pedal did not respond. The vehicle finally locked the wheels and came to a stop. Many warning lights came on rapidly. The message I saw was a braking fault then the car died and all screens shut off. I was half way in the road and now in front of an oncoming vehicle. I couldn't get it to start up. Fortunately the oncoming vehicle slowed and crept around me. My Fisker Ocean the rebooted itself and I was able to get it into the garage. I have under 2700 miles on it. This update 2.0 was promised to fix many of these issues and now put myself and others in danger. I suspect it was the hold function that caused the issue. It seemed like it was trying to stop and hold while I was moving. I contacted the technician who is looking into the data and I reported it to Fisker. This vehicle has been dangerous since it was first delivered. The service techs are trying but the software and build is the issue, which they cannot overcome. Link to photos of previous errors.

The vehicle has several major faults that Fisker is now ignoring and no one has come to fix in the past 2 months. I've submitted multiple tickets and claims. Issue 1: ADAS system. My ADAS system is and has been down since the beginning of February. I have received software updates but that has not fixed the issue. Nothing in any part of ADAS works, causing a massive safety issue. Issue 2: Braking and Regenerative Braking. I believe you are aware of this issue, but when you brake or regenerative braking is engaged, but you then hit a bump, all braking malfunctions and the vehicle accelerates forward. This issue has been persistent for months. There is also a "Brake Malfunction" warning light that appears on start up of the vehicle that requires service. Fisker apparently has no service. Issue 3: My ventilation system is broken (the car is 4 months old) and no longer works and makes an intrusive noise when engaged. Fisker sent me replacement vents (almost a month ago) but no one has called to schedule an appointment to come fix the issues. Other issues: Bluetooth and connectivity malfunctions; interior lighting malfunctions; software issues. The largest issue here is that I am driving a $70K vehicle with major safety issues and no one at Fisker seems to care because they are in dire financial straights.

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 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.
