🔧 Car Fault Reports

Real fixes from real drivers. Browse community-verified fault reports across all makes and models.

This is the master list of every individual fault case on MyCarFault — the same reports you'll find linked from make and model pages, but searchable and filterable in one place. Each entry links to a full case page with owner-reported symptoms, repair attempts that worked (and didn't), confirmed costs, and a community-verified fix rate where enough data exists.

Results are ranked by views and vote count, so the cases other drivers have found most useful surface first.

📖 How to Use This Page

Use the Make and Status filters below to narrow results to your vehicle or to solved-only cases.
The 🟢 / 🟡 / ❌ badges show whether a case has a confirmed fix, a partial fix, or is still unsolved.
Severity tags (🔴 Critical, 🟠 High) flag faults that affect safety or drivability — check these first if your car is showing the same symptom.
If you can't find your exact issue here, try browsing by symptom instead — useful when you don't yet know the technical cause.

❓ Frequently Asked Questions

What counts as a "Solved" fault?

A case is marked solved once at least one repair attempt linked to it has a high enough confirmed fix rate from driver votes and, where available, mechanic verification. "Partial" means some drivers report it helped without fully resolving the issue.
Why are reports ranked by views rather than date?

Views and votes are a better signal of which cases are actually helping people with the same problem right now. New reports still appear immediately on their own case page and in make/model listings — they simply need to accumulate engagement to rise on this combined list.
Can I see fault reports for a specific year of my car?

Yes — open your make and model from the Browse by Make & Model page, where each model's fault list can be filtered by year.
My fault isn't listed here — what should I do?

Use Report a Fault to add it. New reports help other owners with the same vehicle, and you can also flag any repair that turned out to be a wrong diagnosis.
