Our Mission
When a check engine light, HVAC fault, or appliance error appears, you need clear, source-aware context rather than generic descriptions copied between websites.

Our Data Sources
NHTSA Complaints Database
The National Highway Traffic Safety Administration (U.S. Department of Transportation) collects vehicle complaints directly from owners. We use this public complaint data where available to add vehicle-specific context about what owners of your specific vehicle have reported. nhtsa.gov
SAE J2012 / ISO 15031-6 Standard
SAE J2012 / ISO 15031-6 provides standardized OBD-II diagnostic trouble code definitions. We use those standard definitions where applicable, not invented descriptions, to explain what a code may mean.
What Makes Us Different
- ✓ Vehicle-specific data: Real complaint data for your exact make and model, not the same generic text with a different car name pasted in.
- ✓ Government-sourced data: Vehicle complaint statistics come from NHTSA, a U.S. government agency, not user forums or invented content.
- ✓ No safety advice: We show data and source context to support conversations with qualified professionals. We do not tell you whether a vehicle, HVAC system, or appliance is safe to use.
- ✓ Transparent sources: Source notes identify where data comes from so you can verify public vehicle complaint data on nhtsa.gov when applicable.
