What Automotive Engineers Can Learn From Critical Service Downtime In Other Industries

Your Car is Now a Supercomputer with Seatbelts

Today’s vehicles aren’t just transportation – they’re rolling computers managing thousands of critical functions every second. What happens when essential services go dark? Recent outages like Collectors Universe’s week-long certification breakdown provide sobering reminders for automotive engineers. In our world, a software hiccup isn’t just inconvenient; it could mean the difference between a close call and catastrophe.

Why “Pretty Reliable” Doesn’t Cut It for Connected Cars

A coin grading service going offline is frustrating. Your car’s emergency response system failing during a collision? That’s life-altering. We operate in a reality where:

When Systems Fail, Real People Pay the Price

Picture this: you’re relying on your car’s systems when…

• Over-the-air updates freeze mid-install
• Emergency responders don’t receive crash alerts
• Sensors misinterpret road conditions
• Traffic signals can’t “talk” to approaching vehicles

Three critical challenges emerge from recent service failures:

The Dependency Domino Effect: One failed service takes down unexpected systems
Fallback Fantasies: Backup plans that don’t actually work when needed
Update Roulette: Patching systems without breaking critical functions

Learning from CAN Bus: The Veteran of Vehicle Networks

Modern vehicles still rely on the battle-tested CAN bus system. Imagine applying these same fault-tolerant principles to your cloud-connected features.

Redundancy Isn’t Optional – It’s Survival

Just like critical braking systems have backups, connected services need alternate pathways. Here’s how we approach this in vehicle gateways:

// Practical redundancy for telematics connections
function connectToTelematics() {
const mainLink = tryConnection(PRIMARY_ENDPOINT);
if (!mainLink.active) {
triggerAlert('Switching to backup service');
return tryConnection(BACKUP_ENDPOINT);
}
return mainLink;
}

Three non-negotiable rules for automotive connectivity:

• Always maintain multiple communication paths
• Make failover automatic and seamless
• Log every switchover for diagnostics

Cloud vs. Edge: The Automotive Balancing Act

When Collectors Universe went dark, dealers turned to alternative verification methods. Your connected car needs similar contingency plans when cloud services disappear.

OTA Updates That Won’t Strand Your Customers

Smart over-the-air systems borrow from aerospace safety practices:

// Update safety net workflow
1. Cryptographically sign updates at source
2. Verify signature before installation
3. Run parallel checks across multiple ECUs
4. Test update in isolated environment
5. Keep rollback option active for days

This layered approach prevents disasters when:

• Cloud servers get compromised
• Network packets get corrupted
• Unexpected hardware conflicts emerge

Infotainment: Where Drivers Feel the Pain First

When Spotify stops streaming or maps freeze, drivers notice immediately. These “comfort” systems actually teach us important lessons about failure management.

When Third-Party Services Go Dark

Modern dashboards rely on external services for:

• Real-time traffic updates
• Music streaming
• Voice assistants
• Navigation data

Smart timeout protocols keep the essentials working:

const CRITICAL_TIMEOUT = 2000; // 2 seconds max

async function getTrafficData() {
try {
// Attempt primary service
const liveData = await fetchWithTimeout(PRIMARY_PROVIDER);
return process(liveData);
} catch {
// Fail gracefully to cached data
return getLastKnownData();
}
}

Building Safer Cars Through Smarter Testing

Extended outages in other industries reveal testing gaps we can’t afford. Your test suite should be as robust as your braking systems.

Automotive-Grade Testing Pyramid

How do we catch problems before they reach the road?

• Foundation: Rigorous unit tests for safety-critical code
• Mid-Layer: Real-world simulations using actual hardware
• Final Check: Controlled real-vehicle deployments

Our automated gates block any update that doesn’t clear:

// Quality checks that never bend
if (safetyTestsFailed()) abort();
if (coverage < 90%) abort();
if (responseTimesSlowed()) abort();
if (fallbackTriggeredDuringTest()) abort();

The Road Ahead: Engineering Unbreakable Connections

Recent service outages teach us that in automotive tech:

• Redundancy belongs in every design conversation
• Backup systems need real-world testing
• Updates must never create new problems
• External services need circuit breakers

We’re not just coding features – we’re creating systems that people entrust with their lives. While consumer apps can tolerate hiccups, our work requires perfection. Every outage in other sectors gives us new insights for building vehicles that keep people safe, connected, and moving forward – no matter what happens in the cloud.
