The AI-powered virtual automotive diagnostic laboratory
Diagnose real-world problems, test vehicles, interpret scan data, and build technician-level skill in a simulator that scores your reasoning — not your guessing.
No account, no setup. Work one real fault from complaint to root cause in about a minute — then take the same car into the full simulator with the scan tool, multimeter and test drive.
Pick a vehicle. You get the complaint, three pieces of evidence, and one decision — in about a minute.
Every scenario walks the same professional sequence. The platform tracks which evidence you actually gathered before you committed to an answer.
Interview a virtual customer who describes symptoms — never the diagnosis.
Drive the vehicle, watch the cluster, feel the fault appear under load.
Read codes, freeze frame and live data that move with the simulation.
Place multimeter probes on real test points and interpret voltage drop.
Choose cause, confirmation test and repair — guessing scores lower.
Curated vehicle configurations with independently modeled failures.
2018 Honda Accord
The engine started running rough yesterday. The check engine light came on and it feels worse when I'm sitting at a red light.
A8 · Advanced2015 Ford F-150
It stumbles bad when I get on it with a load in the bed, and the light flashes at me. At idle it's mostly fine.
A5 · Beginner2012 Toyota Camry
When I brake coming off the highway, the steering wheel shakes in my hands. It's fine if I'm braking slow around town.
A6 · Intermediate2019 Chevrolet Silverado 1500
The battery light flickers on when I'm idling and my headlights go dim. It's already died on me once in a parking lot.
A2 · Intermediate2016 Honda Odyssey
When it shifts out of second the engine revs up before it catches. It's been getting worse and now it feels like it slips every time.
A2 · Advanced2017 Nissan Altima
It shudders like driving over rumble strips when I accelerate gently around 40 mph, and it bangs into gear when I put it in Drive.
A3 · Intermediate2018 Jeep Wrangler
There's a vibration in the floor that starts around 45 and gets worse the faster I go. New tires didn't fix it.
A3 · Advanced2016 Ram 1500
I push the 4WD button and the light just blinks and never stays on. There's also a clicking sound when I turn hard into my driveway.
A4 · Intermediate2017 Subaru Outback
It drifts to the right if I loosen my grip, and the front tires are shot on the inside edge after only 18,000 miles.
A4 · Beginner2014 Honda Civic
Parking is a workout now. The wheel is heavy and it makes a groaning noise when I turn it all the way.
A5 · Intermediate2015 Toyota Corolla
The ABS light is on and sometimes when I'm almost stopped the brake pedal drops and buzzes like it's doing that anti-lock thing on dry pavement.
A5 · Advanced2016 Ram 1500
Coming down the pass with the trailer, the pedal went almost to the floor and the truck barely slowed. After it cooled off it felt normal again.
A6 · Advanced2016 Chevrolet Cruze
If I don't drive it for two or three days it won't start. The last shop put in a new battery and it did it again.
A6 · Master2019 Ford Escape
Half the dash lit up at once — ABS, traction, power steering, everything. It drives, but the shop said their scanner couldn't talk to it.
A7 · Intermediate2016 Hyundai Sonata
The air conditioning is cold on the highway but as soon as I'm stuck in traffic it turns warm. Then it cools again once I get moving.
A7 · Beginner2019 Ford Escape
My side blows cold no matter what temperature I set, but the passenger side gets hot just fine. There's also a clicking behind the dash when I first start it.
A1 · Advanced2021 Ford Explorer
I have to add coolant every couple of weeks and nobody can find a leak. Sometimes there's white smoke out the tailpipe when it first starts.
A8 · Advanced2016 Hyundai Sonata
Light came back on. Another shop put in two oxygen sensors and it lasted about a week. I need this to pass inspection.
A2 · Advanced2017 Nissan Altima
Around 40 miles an hour it feels like driving over rumble strips, but only when I'm barely on the gas. If I press harder it goes away.
A3 · Intermediate2017 Subaru Outback
There's a whine that starts around 45 mph and gets louder the faster I go. It's the same whether I'm on the gas or coasting.
A4 · Beginner2014 Honda Civic
Every time I go over a bump or a manhole cover the front end clunks. It sounds like something's loose under there.
A5 · Intermediate2018 Honda Accord
When I brake hard the car pulls to the right. There's also a burning smell after I drive on the highway.
A6 · Master2020 Toyota Prius
The dash lights up, the radio works, but the READY light never comes on. It just sits there with a red triangle.
A7 · Intermediate2019 Ford Escape
Some mornings the air conditioning is ice cold. Other days it blows warm the whole trip. Nobody can catch it doing it.
