Unveiling the Mysteries: A Deep Dive into Mechanical Failures and Ingenious Solutions

Initial observations in the Porsche 918 Spyder Hybrid case suggested the owner’s carelessness was the root cause. Typically, leaving a car running or unattended while refuelling could result in minor spillage, but unexpectedly, it led to a severe fire. A pivotal moment occurred when the owner attempted to clean spilled gasoline with a squeegee, inadvertently spreading the fuel and exacerbating the situation.

The involvement of experts from Origin and Cause introduced a nuanced perspective, challenging the notion of the owner’s sole culpability. Their analysis suggested multiple potential causes, emphasizing the case’s complexity beyond initial appearances.

Joint and several liabilities are crucial in such cases, highlighting that any party found even 1% liable can be held responsible for the entire loss. This principle underscores the importance of identifying all potential targets for recovery, especially when the primary liable party may not have sufficient assets. Engaging experts early is critical to uncovering all facets of liability and ensuring a comprehensive approach to subrogation claims.

In investigating the Porsche 918 Spyder Hybrid fire, the approach was to evaluate all possible causes. Initially, arson was considered but quickly ruled out by CCTV footage. Static electricity, proposed by a defendant as a cause, was deemed highly improbable based on the balance of probabilities, a key concept in civil litigation.

The investigation also explored a potential vehicle design flaw, given that cars should not spontaneously combust. This involved a review of similar incidents involving other vehicles, although none directly linked to this case were found.

The functionality of the gas pump nozzle, which failed to stop automatically, was scrutinized alongside the pump’s maintenance history to identify any past issues.

The case highlighted multiple contributory factors, including the owner’s decision to leave the car running and attempt to clean spilled fuel with a squeegee. This comprehensive examination underscores the complexity of determining liability in subrogation claims.

The catastrophic failure of the Porsche 918 Spyder Hybrid incident resulted from several contributing factors. Key among these was the driver’s contributory negligence, highlighted by leaving the vehicle running during refuelling and attempting to clean up spilled fuel with a squeegee. These actions were fundamentally unsafe and significantly impacted the event’s outcome.

The case’s further investigation revealed a complex mixture of contributing factors. A significant vehicle defect necessitated a recall due to a wire harness near the fuel tank, which caused electrical arcing and ignited fuel vapours. This issue, compounded by the fact that similar vehicles had experienced related problems, highlighted a broader concern.

Additionally, the gas pump involved had a history of overflowing on three occasions, a fact known to the gas station, which failed to act on this information. This negligence shifted part of the liability to the gas station, underscoring the importance of maintenance and the potential consequences of inaction.

The case emphasized the necessity of a comprehensive approach to subrogation claims, exploring all possible liabilities. The discovery of the gas station’s prior knowledge and maintenance lapses, alongside the vehicle’s defect, showcases the multi-dimensional nature of such incidents. Expert analysis further confirmed that the outdated pump nozzle, not replaced promptly, contributed to the incident, highlighting the importance of regular maintenance and equipment updates to prevent catastrophic outcomes.

Lesson Learned

This unique and complex case provided several critical lessons for future endeavours. The first lesson is that the most straightforward answer is only sometimes complete. Initially, it seemed a straightforward case of the owner’s careless leaving the vehicle running during refuelling. However, a deeper investigation with the help of Origin and Cause revealed other significant factors contributing to the incident, leading to a more fruitful recovery.

The process underscored the necessity of remaining open to evolving theories and perspectives. As highlighted, “no idea is a bad idea,” and a holistic approach to analysis is crucial. New facts and documents often emerge throughout the litigation, necessitating a reevaluation of positions and strategies. This case exemplified the importance of including additional parties to widen the net of potential liability, which was achieved by paying close attention to the investigation’s details.

Further insights were gained regarding liability distribution across multiple parties. This approach prevents settling too quickly on a single theory and allows for strategic evolution as the case develops. The case also demonstrated the value of thorough investigative work in bringing additional liable parties to the table, which would have been overlooked if the focus remained solely on the driver’s actions.

A practical decision to retain the gas pump for testing proved instrumental in solidifying the cause of the loss and presenting a robust theory to the opposing parties. This meticulous approach enabled the consideration of the gas station and its maintenance contractors’ roles, broadening the liability spectrum.

The case concluded with a broader recovery perspective, showing that involving multiple parties with liability exposure facilitates a more optimal settlement. This strategy is more effective in large-scale cases, making distributing the financial burden among several contributors easier.

A final, more practical lesson reflects on the value proposition of vehicles. Owning an expensive vehicle might only sometimes be the wisest choice, especially considering the potential for severe implications in case of loss, contrasting with the lesser impact associated with more reasonably priced vehicles.

Case Study 2: Fire Starter

This incident involves a vehicle that was left overnight in a repair shop. A fire originated within its engine compartment. The car was turned off at the time, having undergone some troubleshooting. The repair team had already diagnosed the issue and was awaiting a part needed for the repair.

The vehicle underwent an initial examination at the loss location within the shop, with plans to share some of those photos later. Subsequently, it was reexamined at a different location in a yard where it had been moved. A preliminary scene examination is typically the first step in cases like this. In this instance, Mike Owens, a colleague, conducted the initial assessment and determined that the fire had originated from the vehicle’s engine compartment.

Once the various parties involved in the incident were identified, they were notified, and a joint examination of the vehicle was scheduled to occur involving all relevant parties. This procedure is standard practice in such cases, ensuring a thorough and collaborative investigation process.

In this case, representatives from the shop, the vehicle owner, and the vehicle manufacturer were present, including the shop’s insurer and the vehicle owner’s insurer. The shop owner also owned the building, eliminating the need to involve a landlord. The investigation focused on the vehicle, especially the engine compartment where the fire originated. The fire caused limited spread to the shop and resulted in smoke and water damage.

Interviews revealed that the vehicle was purchased used, equipped with two key fobs featuring remote starter capability, confirmed to be factory-installed rather than aftermarket. This detail was crucial in narrowing down the investigation to exclude potential aftermarket installations as the fire’s cause, a standard line of inquiry to identify responsible parties, including manufacturers of installed components and installers.

Years after the purchase, the owner noticed a rat exiting the vehicle’s underside, and about a month later, the engine light activated. The car was then taken to the shop, where technicians discovered chewed wires. After initial repairs, the check engine light was reactivated, leading to another shop visit. Further troubleshooting identified a faulty fuel injector needing replacement. The technician removed parts, including fuel rails and the intake manifold, in preparation for the new injector’s installation. The shop closed at 5:00 p.m., and by 10:30 p.m., smoke detectors were activated, leading to the fire department’s response to smoke emanating from the garage door in front of the parked vehicle.

The shop utilized a Snap-On scanning tool on the day of the loss to diagnose the engine problem, which identified misfiring in cylinder 3. Initially, the ignition coil in cylinder three was tested, followed by the spark plug. After swapping parts into different cylinders and retesting, it was ultimately determined that the fuel injector in cylinder three required replacement. However, the necessary part was not in stock at the shop, so it was ordered to arrive the following day in accordance with the manufacturer’s procedures.

For the replacement of a fuel injector, it was determined that disconnecting the vehicle’s 12-volt battery was not necessary. Consequently, the hood was left open overnight as the shop closed, with plans to complete the work the following morning. The photos show the remaining key fob, which was at the vehicle owner’s home, located about a kilometre from the shop. The key fob used to drive the vehicle into the shop was left on the dash by the technician, adhering to his standard practice to avoid misplacing the customer’s key fob while working on the vehicle. In the photograph mentioned, the car is positioned facing the north wall, though this detail is not visible in the image.

The north wall is where the vehicle faced, near the garage door of the shop, and it remained unmoved or unaltered during the preliminary examination before the joint destructive examination with all parties present. Evidence of fire damage to the building is also noted, although the severity of the fire damage at the front of the vehicle is not visible in the provided description, which will be shown in the next slide. It’s highlighted that there was significant fire, smoke, and heat damage to much of the wiring and other components within the building, which was also of historic significance.

In the photo presented, it’s shown that the engine cover, intake manifold, and fuel rails were removed from the engine as part of the mechanics’ troubleshooting process before the fire occurred. These components were placed on a cart right beside the vehicle. The photograph reveals severe fire damage to the front of the car. The vehicle and the surrounding area were cordoned off to maintain scene integrity during the preliminary examination. However, to reduce the loss for the shop, cleanup and repairs commenced swiftly, with careful consideration to avoid disturbing the area of fire origin. This area was demarcated explicitly by evidence tape that Mike Owens had positioned around the vehicle during his preliminary examination, and on this cart, the fuel rails and the engine cover are visibly intact.

In this context, it is indicated that viewers can see the cursor movement; thus, the presenter uses the cursor to point out specific items. The two bars highlighted by the cursor are identified as the fuel rails from the engine, and another component pointed out is the underside of the engine cover that had been removed. Following this, there is a transition to discussing the fire.

Damage within the engine compartment, noting a distinctive pattern on the engine side of the firewall. The firewall acts as a bulkhead, extending below what is visible in the photo dividing the engine compartment from the passenger or interior side of the dash. A specific pattern observed near the firewall was intriguing early in the investigation, raising questions about its origin in a parked and turned-off vehicle. Typically, an investigation would focus on electrically started fires, yet no live electrical conductors were found in that area.

The loss of material and patterns on the remaining metal surfaces within the engine compartment confirmed the fire originated there. Since the vehicle had been parked for several hours before the fire, hot surface ignition of flammable liquids or vapours was ruled out as a cause. This pointed to the vehicle’s electrical system as the only plausible source of the fire. Furthermore, the possibility of an intentionally set fire was dismissed after discovering that the shop utilized video surveillance and an alarm system.

The car had been parked and off for an extended period, with the investigation focused on the vehicle’s electrical system to determine a potential electrical failure as the fire was caused. Despite the fire starting in the engine compartment and the body control module being located in the driver’s side dash, the investigation still needed to explore whether there was a failure in the body control module that could have contributed to the fire’s ignition.

The engine control module (ECM) and body control module (BCM), both integral to the vehicle’s electrical system, were closely examined. These modules, acting as small computers, receive data from various sensors and control different vehicle systems. The ECM, located forward of the battery and the power distribution center, showed no evidence of catastrophic failure. The wires connecting to the ECM were brittle and fractured when handled, but the internal components were in reasonably good condition, making it difficult to isolate a potential malfunction.

The BCM showed severe fire damage, complicating efforts to determine if a failure within this module contributed to the fire. Surveillance video footage, reviewed later, captured the fire’s inception while the vehicle and shop were unattended. Notably, before the fire erupted, the vehicle’s tail lights illuminated, suggesting an electrical activity or malfunction preceding the fire’s rapid escalation in the engine compartment.

This sequence of events, including the tail lights’ illumination followed by the vehicle seemingly starting itself and the immediate engulfment of the engine compartment in flames, pointed towards an electrical malfunction as a significant factor in the fire’s origin. The investigation meticulously examined the primary wiring, which was alive at all times due to direct battery connection, for any arcing failures or malfunctions that could ignite the fire. Despite the exhaustive examination, no definitive evidence of an arcing failure was found in the live electrical system that might have contributed to the ignition scenario.

The vehicle owner had reported that, over the years, the trunk had spontaneously opened about twelve times without anyone pressing the button on the key fob. This included instances while driving and finding the vehicle with its trunk open in the driveway. After researching and beginning to lock the car consistently when parked, the issue did not recur.

A search for recalls or Technical Service Bulletins (TSBs) related to fire hazards yielded no relevant findings on Transport Canada, NHTSA (the American equivalent of Transport Canada), or automotive databases like Mitchell One or ProDemand. These resources also provide technicians with access to procedural guidelines, such as those for replacing a fuel injector.

Further investigation revealed a hood switch installed at the factory, designed to prevent the vehicle from being remotely started with the hood open, enhancing safety for technicians during maintenance. This feature ensures that accidental vehicle starts don’t occur, even if someone attempts to remotely start the vehicle with a second key fob while the hood is open.

The vehicle’s owners clarified they had never used the mobile app associated with the vehicle’s remote start system and were at home at the time of the fire. Therefore, the possibility of the engine accidentally starting due to the second key fob was ruled out. Moreover, since the check engine light was on and error codes were present, the vehicle’s remote start system would not have been operable, eliminating it as a cause of the engine starting.

What Happened

The ignition sequence captured in the video, with the turn signal lights flashing before ignition, suggested active parts of the system, pointing to a potential failure in either the Body Control Module (BCM) or the Engine Control Module (ECM). This failure could have caused the ignition system to energize and start the engine directly, bypassing the remote starting system.

Unlike the process initiated by the remote start system, where the taillights flash, the same does not occur when the engine is started manually from inside the vehicle. This detail led to the conclusion that the observed ignition sequence was related to the remote start system. The accidental activation of the start button on the key fob at home was ruled out, focusing the investigation on the vehicle itself.

The remote vehicle start sequence involves the BCM receiving a signal from the fob and verifying certain conditions before activating the ignition system. It was considered that the BCM might have experienced an internal failure, as the vehicle attempted to start regardless of the hood’s position, suggesting a malfunction in the BCM or ECM.

The investigation noted that the fuel rails and fuel injectors had been removed from the engine, but the high-pressure fuel pump was still present and capable of pushing fuel into the engine compartment. This fuel likely vaporized and was ignited by a spark from the starter, alternator, or spark plug that remained in the engine, leading to the fire.

Lesson Learned

The second case study, revolving around a mysterious fire that ignited in a vehicle’s engine compartment while it was parked overnight in a repair shop, brings to light several critical lessons in the realm of mechanical investigations. This intricate scenario underscores the nuanced complexity of modern vehicle electrical systems, demonstrating how the potential for electrical malfunctions remains a significant risk even when a vehicle is turned off. The investigation into this incident revealed the paramount importance of thorough investigative procedures, where every aspect, from environmental factors, such as rodent interference, to the meticulous examination of electrical components, plays a crucial role in unravelling the mystery behind such unanticipated events.

Moreover, this case highlighted the limitations of safety mechanisms intended to prevent such incidents, pointing to a need for continuous improvement in vehicle safety features and the methodologies used to test these systems. The collaborative nature of the investigation, involving multiple stakeholders, reinforced the value of a unified approach in dissecting complex cases, ensuring a comprehensive exploration of all potential causes and liabilities.

The saga of the vehicle catching fire due to an electrical malfunction, despite safety measures like the hood switch designed to prevent remote starts with the hood open, serves as a stark reminder of the unpredictability and potential dangers inherent in vehicle maintenance and repair. It also reflects on the importance of legal and financial preparedness for individuals and businesses alike, as such incidents carry significant legal and financial implications.

In essence, the Fire Starter case study not only deepens our understanding of the intricacies involved in vehicle electrical systems and the unforeseen risks they harbour but also emphasizes the need for ongoing education, awareness, and technological advancement to mitigate such risks.
