🚫 Do not drive — If the ignition system is failing, the vehicle is inoperable and cannot be started or driven.
Key Takeaways
  • A no-start condition is often caused by the Body Control Module (BCM) losing its programming after the 12V battery dies, not a faulty ignition switch.
  • Replacement of the ignition switch or BCM is NOT a plug-and-play repair; it requires mandatory programming by a Fisker specialist.
  • There is no traditional dealer network; service must be done at one of a few independent shops in North America with the correct diagnostic tools.
  • Symptoms of failure include a completely 'dead' car that won't 'boot up' when the start button is pressed, even with charged batteries.
The ignition switch in the 2011-2012 Fisker Karma is not a traditional mechanical switch but a push-button module, often called the Start/Stop Button (SSB). Its job is to initiate the vehicle's complex power-up sequence. When pressed, it sends a signal to the Body Control Module (BCM) and other computers to 'wake up' the car, check the status of the high-voltage and 12-volt batteries, and energize the systems required to enter 'Ready' mode. It is a critical link in the car's sophisticated electronics and immobilizer system.

Symptoms of a Failing Ignition System

The most alarming symptom of this failure is a completely unresponsive vehicle. Even with a charged high-voltage battery, the infotainment screen remains black and the start button will not illuminate.

Because the Fisker Karma relies on a complex electronic startup sequence, a problem with the ignition system can manifest in several ways. These symptoms often point to a communication breakdown between the key, the ignition button, and the vehicle's main computers.

Complete No-Start or 'No Boot-Up' Condition

The most common and alarming symptom is a car that appears completely dead despite having a charged battery. Owners report pressing the start button and getting no response. Specifics include:

  • The Start/Stop button does not light up.
  • The main infotainment touch screen remains black.
  • The car is stuck in Park (P) and cannot be shifted.
  • 🎬 Watch: How to fix common shifter control issues.
  • Some basic electronics like interior lights or hazard lights may work, but the car will not enter Accessory (ACC) or Ready-to-Drive mode.
  • This can occur even with a fully charged high-voltage main battery and a brand new 12-volt battery.

Intermittent Electrical Problems

A failing ignition switch or related control module can also cause unpredictable electrical behavior. This might include dashboard lights flickering, accessories shutting off unexpectedly, or the car stalling while in motion, though the 'no boot-up' issue is more frequently reported by Karma owners.

Warning: A complete loss of power while driving is a critical safety issue. If your vehicle exhibits any signs of stalling or intermittent power loss, it should be serviced immediately by a qualified specialist.

The Real Culprit: BCM, 12V Battery, and Immobilizer Link

An automotive Body Control Module (BCM) which manages the vehicle's immobilizer and key fob synchronization.
Often, the ignition button itself is fine. The true culprit is usually the Body Control Module (BCM) losing synchronization with the key fob after the 12-volt battery dies or is disconnected.

For many Fisker Karma owners experiencing a no-start condition, the ignition button itself is not the faulty component. The issue often lies with the Body Control Module (BCM) and its relationship with the 12-volt battery and the vehicle's immobilizer system.

A common scenario occurs after the car's 12V battery has been disconnected or has died completely. When the BCM loses all power, it can lose its synchronization with the vehicle's key fobs. When a new 12V battery is installed, 🎬 See this guide on 12V battery location and replacement. the BCM fails to recognize the 'wake up' signal from the key, leading to a no-start condition that perfectly mimics a failed ignition switch. In these cases, the BCM and key fob need to be reprogrammed together for the vehicle to function again.

Step-by-Step Diagnosis

Always start your diagnosis by verifying the 12-volt battery's health. A voltage drop below 12.2 volts is enough to cause communication errors between the Karma's modules.
  1. Check the 12V Battery: Before suspecting any major component, ensure the 12-volt battery is fully charged 🎬 Watch: How to properly jump start the Fisker Karma. and the terminals are clean and tight. A voltage below 12.2 volts can cause communication errors between modules.
  2. Check the Key Fob Battery: A weak or dead battery in the key fob can prevent the car from detecting the key, which is necessary to authorize the start sequence.
  3. Attempt a System Soft Reset: Some electronic glitches can be solved with a soft reset. Turn the car off, take the key fob at least 10 feet away from the vehicle, and wait for more than two minutes. This allows all systems to go to sleep. Re-enter the car and try starting it again.
  4. Scan for Codes: Use an OBD-II scanner to check for trouble codes. Be aware that the Fisker Karma may show a generic code like P07AB (Battery Pack Cell Voltage Low) which indicates a general battery system fault but requires specialized diagnostic tools to pinpoint the exact cause.

Buying a Used Ignition Switch

When sourcing a used ignition switch, carefully inspect the electrical connector. Avoid any parts showing green corrosion, bent pins, or heat-warped plastic housings.

If the ignition switch assembly (Part No. C131180903001) is confirmed to be faulty, finding a replacement can be challenging. Aftermarket options do not exist for this vehicle, leaving used OEM parts as the only viable solution.

  • Verify the Part Number: Always match the part number C131180903001 to ensure you are getting the correct component for your 2011-2012 Karma.
  • Physical Inspection: When buying a used switch, inspect the electrical connector pins for any signs of corrosion, bending, or damage. Check the plastic housing for cracks or heat-related warping.
  • The Programming Requirement is Key: A used ignition switch is NOT a plug-and-play part. It is tied to the vehicle's immobilizer system. You cannot simply swap it and expect the car to start. The part must be programmed to your vehicle's BCM and keys by a specialist with the proper equipment.

Programming & Service: A Specialist is Required

Due to the bankruptcy of the original Fisker Automotive, there is no longer a traditional dealer network. However, several independent shops specialize in servicing these vehicles. They have the necessary factory training and diagnostic tools, such as the Fisker Workshop Tester (Prodis), to perform software updates and module programming.

Any replacement of the ignition switch, Body Control Module (BCM), or key fobs will require a visit to one of these specialists for programming. This is not a procedure that can be performed by a general mechanic or a locksmith.

Known Fisker Karma service specialists in North America include:

  • Pat's Garage (San Francisco, CA)
  • Roush Restorations (Peoria, IL)
  • Fluid Motor Union (Naperville, IL)
  • EVolution Autosports (Philadelphia, PA area)
  • Drambo Motors (Phoenix, AZ)

Known Issues, Recalls, and Technical Service Bulletins (TSBs)

While there are no recalls specifically for the ignition switch, several recalls and TSBs are relevant to the vehicle's electrical system.

  • NHTSA Recall 12V241000: Risk of coolant leaks into the high-voltage battery, potentially causing an electrical short and fire.
  • NHTSA Recall 12V413000: A defect in the low-temperature cooling fan could cause a short and lead to a vehicle fire.
  • TSB 390110015.01 (Baseline 611): A crucial software update that improves range accuracy and removes unnecessary warning lights during the vehicle's 'wake up' process. Ensuring your vehicle has this update or a later version can solve many electronic gremlins.

Frequently Asked Questions (FAQ)

Does a used Fisker Karma ignition switch need to be programmed?

Yes, absolutely. The ignition switch is part of the immobilizer system. A replacement switch, whether new or used, must be electronically paired to your vehicle's Body Control Module (BCM) and keys by a specialist with Fisker-specific diagnostic tools. The car will not start without this procedure.

Can I replace the ignition switch myself?

While the physical removal and installation of the switch may be possible for an experienced DIY mechanic, it is not recommended. The replacement is incomplete without the final, mandatory programming step, which requires specialized equipment that only a few shops in the country possess.

My Karma won't start but the lights work. Is it the ignition switch?

It's possible, but it is more likely related to the 12-volt battery or the Body Control Module (BCM). If the 12V battery has recently died or been replaced, the BCM may have lost its programming and no longer recognizes the key. This is a common failure point that requires professional diagnosis and reprogramming.

Where can I get my 2012 Fisker Karma serviced?

Since the original dealer network is gone, service must be performed by independent specialists. Well-regarded shops with the necessary tools and expertise are located in California, Illinois, and Pennsylvania, among others.
