A same-day scan tells you where the car is today. Guardian watches what changes over weeks and months — battery capacity, 12V behavior, charging, thermal load, and air-suspension compressor activity — so slow failures don't stay invisible until the repair bill arrives.
My own Model X air-suspension repair was $5,612 CAD.
Guardian exists for the weeks before that invoice — when the car still drives normally, but the data is already starting to change. The point isn't to predict every failure. It's to stop owning the car blind.
What Guardian watches
Each subsystem, learned as this car's own normal — so a quiet drift becomes an early warning instead of a roadside surprise or a five-figure invoice.
Air suspension
Compressor-runtime baseline from parked windows. A slow air leak shows up as rising compressor work weeks before the car visibly sags — the failure mode that cost me $5,612.
12V & charging
Sleep voltage, parasitic drain, and charge behavior. The #1 cause of a Tesla that won't wake up — seen as a trend, not as a dead car in a parking lot.
Battery & thermal
Real capacity trend (CAC), cell balance, coolant and stator load. The pack fades silently and the range number hides it — the trend doesn't.
Live proof
This isn't a mock-up. Below is real continuous data from a 2017 Model X 100D.
Health Passport — turn your ownership history into resale evidence
Ready to sell? Guardian turns months of ownership history into buyer-readable resale evidence.
Instead of asking buyers to trust a clean listing photo, you can show the car's actual monitoring history: battery trend, charging behavior, suspension-compressor baseline, safety checks, and the signals that stayed normal over time.
When it's time to sell, months of validated history become a buyer-readable record of how the car was actually charged, driven, and maintained. Used-market studies put the premium for documented, auditable history at 5–15%. It answers "what did the previous owner do to it?" with evidence instead of "trust me." Selling a car you didn't monitor from day one? A one-time inspection snapshot still documents its current state.
