Example Diagnoses
See what a real CarFixAI diagnosis looks like
Check Engine Light - P0420
Catalytic Converter Efficiency Below Threshold
The oxygen sensors detected that your catalytic converter isn't cleaning exhaust gases efficiently. This is often caused by a failing catalytic converter, but can also indicate oxygen sensor issues or exhaust leaks.
Brake Noise - Squealing
Worn Brake Pad Indicator
The squealing noise indicates your brake pads have worn down to the wear indicator. This metal tab creates noise to alert you it's time for new pads before they damage the rotors.
Fluid Leak - Green
Coolant Leak
The green fluid under your car is engine coolant (antifreeze). Driving with low coolant can cause severe engine damage from overheating. Common leak points include hoses, water pump, and radiator.
Success Stories
Real users, real savings
"My AC stopped working in the middle of summer. The shop wanted $1,200 to replace the compressor. CarFixAI diagnosed it as a blown fuse - $5 fix that took 10 minutes."
"Check engine light came on during a road trip. CarFixAI told me it was just a loose gas cap. I was able to continue my trip without worrying or finding a mechanic in an unfamiliar city."
"Used CarFixAI to diagnose a transmission code. Turns out it was low fluid, not a failing transmission. Added a quart of ATF and the code cleared. Shop wanted to rebuild the whole thing."
"My brakes were making noise and I was quoted $600 for pads and rotors. CarFixAI showed me I only needed pads and they were within spec. Did it myself for $45."
