When the Battery Pack

Becomes the Critical Vulnerability — A Lesson in Safety, Systems & Strategy

On November 4, 2025, Stellantis issued a major recall: over 320,000 plug-in hybrid vehicles—specifically, the Jeep Wrangler 4xe (2020-25) and Jeep Grand Cherokee 4xe (2022-26) models—were found to have high-voltage battery packs that may fail in a way that could cause fire.

This recall isn’t just about cars. It’s a wake-up call for any organization working with lithium-ion battery systems.

At Kevin Doyle Consulting, we view this as a vantage point to explore three critical dimensions: the technical defect, operational risk response, and the leadership/communication imperative.The Technical Root: Why the Lithium-Ion Battery Was the Weak Link

• The recall documents show Samsung SDI America supplied the battery packs, and a key defect is “separator damage” in the battery cells: the separator is the thin membrane between the anode and cathode, preventing short circuits. When it fails, thermal events (fires) become possible. 

• What makes this more serious: The defect appears even in vehicles previously recalled and repaired under earlier systems, showing that the first fix (a software update) did not fully mitigate the failure mode.

• The recall instructions require owners to “not charge the battery” and to “park outside away from structures,” as the risk is higher when the battery is fully charged. 

Takeaway for organizations: It emphasizes how a component often taken for granted (the battery cell separator) becomes a single point of failure with systemic implications. Risk management must identify such latent vulnerabilities early—even in “commodity” parts.

2. Operational & Risk Management Implications

• Recall readiness: The fact that this defect persisted after an initial remedy shows that the “fix and forget” mindset is dangerous. Systems must include robust validation and follow-through for remedial actions.

• Communications & stakeholder management: Owners are immediately told to take protective actions (park outside, stop charging) before a solution is available. This situation requires clear, consistent messaging and transparency.

• Safety culture: The instruction to park away from structures underscores how safety decisions extend beyond the device or vehicle—they impact property, people, and infrastructure. Cross-functional coordination (engineering, customer service, legal, communications) is required.

• Are our first responders trained to respond to Li-ion failures with the appropriate PPE? 

Consulting lens: For manufacturers, service networks, fleet managers, or safety professionals, this recall is a case study in how a design/manufacturing flaw becomes a business risk—and how operational planning, supply chain oversight, and communication strategy must all interlock.

3. Leadership & Strategic Response
As a leader, whether you oversee product safety, facilities, manufacturing, or service operations, here are questions to ask:

• Have we audited our systems for “hidden failure modes” (like separators, connectors, interfaces) rather than just the headline components?

• Do we have escalation triggers in place when early incident reports (even a small number) suggest a growing trend?

• Is our communication chain ready for rapid owner/end-user notification, interim safeguards, and full remedy rollout?

• Are we prepared for the reputational dimension—not just the technical fix, but how the market, regulators, and customers will view our response?
  This is what distinguishes an organization that simply “reacts to recall” versus one that masterfully manages risk, preserves brand trust, and accelerates corrective action.

Conclusion
The Jeep recall is more than an automotive story. It’s a high-voltage alert for any system in which safety, complex components, regulatory risk, and public communication converge. At Kevin Doyle Consulting, we’re helping clients build the frameworks for anticipation, resilience, and clear communication when the stakes are real—which they are today.
If your team works with hybrid/electric systems or Li-Ion Batteries, let’s connect and make sure you are set to lead.
