Video ReviewCanarsie, Brooklyn

"He came right to my block in Canarsie. Check engine light had been on for weeks — Lionel plugged in, told me exactly what was wrong: three cylinders misfiring on my 2016 Infiniti QX70. Didn't guess, didn't upsell. Sent me to a shop he trusted and they fixed it the same day."

Check Engine Diagnosis

My check engine light had been on for weeks and I kept putting off the tow. Riv Tech came to my building's parking garage in under two hours. They had the codes read, explained everything clearly, and I knew exactly what to tell the shop. Saved me a ton of time.

Crown Heights, Brooklyn

I was buying a used car in Astoria and didn't want to get burned. They showed up, ran a full diagnostic, and found a transmission fault code the seller hadn't disclosed. Absolutely worth it.

Fleet Diagnostics

We run a 12-van delivery fleet out of Sunset Park. Riv Tech comes to our lot every month for preventive diagnostics. They've caught issues before they became breakdowns. Our downtime is way down since we started using them.

James W.

Operations Manager, Sunset Park, Brooklyn

Fast, professional, and they actually explain what the codes mean in plain English. No upselling, no pressure. Just honest diagnostics.

David K.

Riverdale, The Bronx

I manage a small car service company in Staten Island. Getting vehicles to a shop during business hours was always a headache. Riv Tech changed that completely — they come to us, the report is thorough, and the techs actually know what they're talking about. We've referred three other operators to them.

Carmen R.

Owner, Staten Island Car Service

Booked online at 9pm, they were at my car by noon the next day. The diagnostic report was emailed to me within the hour. Exactly what I needed.
