What real used-car buyers are saying.
EngineCheck started with 20 beta testers — friends and early users shopping for used cars across Canada. Here's what they came back with.
Used it before buying a 2015 Civic. Flagged a belt squeak I hadn't noticed. My mechanic agreed.
Walked away from a sketchy Jetta after seeing the Higher risk score. Glad I did.
Flagged a cold-start tick on a 2017 Subaru. Mechanic confirmed valvetrain wear two days later.
The seller questions list alone was worth the $15. Got the price down $1,200.
Quick check on a Marketplace BMW caught enough red flags before I drove 2 hours to see it.
I'm not a car person. The report broke things down in a way I could actually use at the dealer.
Ran it on three Audis in one week of shopping. The reports were consistent and useful.
Listed BMW had a timing-chain concern flagged. Independent mechanic backed it up.
Felt honest — didn't try to scare me into worst-case findings. That's why I trust it.
Tested it on my own truck where I knew the issues. Picked them up correctly.

Tested it on my own truck where I knew the issues. Picked them up correctly.
Saved a $200 pre-purchase inspection on a car I was already walking away from.
Used it to negotiate after the mechanic visit. Both flagged the same two things.
Forwarded the email straight to a Honda dealer for a trade-in conversation. Solid context.
Free quick check told me to inspect. Paid one told me exactly what to look at.
First used-car purchase. The report made me a lot less anxious going into the test drive.
Caught a cold-start knock on a Corolla I'd already lined up. Walked away.
Almost bought sight-unseen from another city. Asked seller for an engine video first.
I don't know cars. This made me feel like I had someone who did, on call.
The questions-to-ask-the-seller section was the most useful part for me.
Lower risk on a Mazda 3, clean test drive, mechanic green-light — bought with confidence.

This is a second opinion — not a replacement for a mechanic.
EngineCheck is a fast pre-screening tool. Our analysis is based on submitted audio, video frames, and the details you provide. It is not a certified mechanical diagnosis. Before purchasing any used vehicle we strongly recommend a pre-purchase inspection by a licensed mechanic. Every report ends with a verification checklist designed exactly for that conversation.
Common questions.
How accurate is the AI?
Engine sound analysis from a phone video has real limits. We design the report to be conservative — flagging possibilities, not diagnosing. Every report ends with a checklist to verify with a licensed mechanic. Treat it as a fast first filter, not a final answer.
What kind of video should I upload?
30–60 seconds, recorded from the engine bay or close to the front of the car with the hood open. Cold start is most useful. Make sure the audio is clear — minimize background noise where possible.
How long does the report take?
Most reports are generated and emailed within a few minutes of payment. If we hit unusual traffic we'll notify you — you always get a report, or your money back.
Can I use this for any car?
Yes — any internal-combustion used car. EVs are not supported (different fault signatures). Hybrids work for the ICE side only.
Refund policy?
If the report didn't help, just reply to your report email within 14 days and we'll refund you, no questions.
