Frequently Asked Questions

Is AutoProblemAnalyzer free?+
Yes, completely free. No account, no email, no credit card. Just describe your symptom and get answers.
Where does the cost data come from?+
All repair cost ranges are sourced from published industry data including RepairPal, AAA, and NAPA. Every estimate shows its source and date so you can verify it yourself.
Should I stop driving if I see a symptom?+
Each symptom shows an urgency level based on its worst-case cause. If you see "Stop Driving" or "Urgent," it may be best to have the vehicle towed or inspected before driving further. When in doubt, err on the side of caution.
Can I use this for any vehicle?+
Most symptoms apply to all passenger vehicles. Where a symptom is specific to certain makes or drivetrains, the page notes it. Cost ranges reflect national averages and may vary by vehicle and region.
Do you track me or sell my data?+
No. AutoProblemAnalyzer does not require an account, does not use cookies for tracking, and does not collect or sell personal data. Your searches stay on your device.

Why Trust AutoProblemAnalyzer?

Every cost range on this site comes from published repair data — primarily RepairPal and AAA — not guesswork. Each estimate links directly to its source so you can verify it yourself.

Urgency levels are set to the worst-case cause, not the most common one. If a grinding brake noise could mean debris or metal-on-metal pad failure, we show the urgency for pad failure. We would rather you act cautiously than assume the best.

We use hedged language throughout — “may indicate,” “commonly caused by,” “typically costs” — because only a qualified mechanic who physically inspects your vehicle can give a confirmed answer. This tool helps you walk into the shop informed, not replace the inspection.

AutoProblemAnalyzer does not track you, does not require an account, and does not collect or sell personal data. No cookies, no behavioral fingerprinting, no email harvesting. The tool works entirely in your browser.
