"I work in semiconductor manufacturing. When my Model 3 had a BMS fault I needed someone who would treat the diagnostic like a bug report. Priya did. The 7-page PDF was exactly what I would have asked for."

"Bearing replacement on the rear drive unit of my 2018 Model X. Tesla SC quoted full drive unit replacement at $6,400. Voltline did the bearing swap for $1,900. The whine is gone. The diagnostic report identified the exact bearing."

"Diego diagnosed the Lexus RX450h transaxle whine my dealer said 'sounds normal.' It wasn't. MG1 bearing micro-pitting. Repaired without a transaxle replacement. The dealer would have replaced the whole unit for $5,800."

I work in semiconductor manufacturing. When my Model 3 had a BMS fault, I needed someone who would treat the diagnostic like a bug report. Priya did. The 7-page PDF was exactly what I would have asked for as an engineering customer. Module identified. Pack rebalanced. Code cleared. Done. — Senior staff engineer · Intel Ronler Acres · 2019 Tesla Model 3
Leave a Review

If we did good work, tell other engineers.

The fastest place to leave a Google review is Google Maps. We also accept reviews via Tesla Motors Club's "Recommended Independent Shops" thread, RepairPal, and the Plug-In America independent-EV-shop directory. We do not solicit reviews. We do not offer discounts for reviews. If the work was good, we appreciate the time it takes to write one.

Diagnose first. Quote second. Never upsell.

That is how 1,847 hybrid rebuilds and ~340 active EV customers happened.
