Diagnostics
Find the problemEV Diagnostics
Unknown issues and alerts? Service Mode Plus scan of all vehicle systems. On-site check up. Fault codes, battery health estimate, and written findings. A great starting point for any unknown issues.
Remote Diagnostics
Don't need on-site diagnostics? Send us your VIN and Tesla account email address, and we remotely read your diagnostics and let you know what's going on with your car.
High Voltage Diagnostics
Do you have a High Voltage issue with the main battery? We can diagnose onboard charger faults, charge port issues, battery pack health, and 12V system charging failures.
Inspections
Know before a deadlinePre-Purchase Inspection
Buying a used Tesla? We inspect battery health, safety systems, hidden faults, and repair estimates before you sign anything. You can use this info for extra negotiating power before you buy!
Basic Warranty Inspection
Coming up on 4 years or 50,000 miles? That's when your bumper-to-bumper warranty ends. We inspect for defects Tesla should fix free while you're still covered — and give you an honest list of what's just wearing out, including the tires, brakes, and alignment Tesla won't cover anyway. Go in informed, not surprised.
Battery & Drivetrain Warranty Inspection
Your battery and drive unit are covered 8 years — to 100k, 120k, or 150k miles depending on model — but only down to 70% capacity. Before that window closes, we run the same pre-expiration inspection Tesla charges for, plus a full 24-hour battery calibration and a written capacity report — so if you've got a claim, you catch it in time.
Service & Repair
Fix it and maintain it12V/16V LV Battery Replacement
Having warnings and alerts to replace your Low Voltage battery? 12V/16V battery replacement, and low-voltage diagnostics. We'll pick up and install the LV battery for your car, same day.
HVAC Tune-Up
HVAC blowing hot air in the middle of a CA heat wave? We perform a full tune-up of your HVAC system to get it blowing ice cold again! Includes a refrigerant top-up and cooling performance testing.

Not sure if you're in range?
Aerospace-trained. Marine-disciplined.
EV-obsessed since 2018.
Ray Novelo was a satellite and radar technician in the U.S. Marine Corps, then an Aerospace-trained electrical specialist — before a broken window regulator on his own car pulled him into the EV world. He apprenticed at Tesla-specialized garages starting in 2018, launched his own mobile service in 2023, and hasn't looked back. Every job gets a written report. Every price is quoted before work begins.
