Frequently Asked Questions
Does a battery warning mean I need a new battery?
Usually not. Most warnings trace to a specific module, sensor, contactor, or the cooling loop. We diagnose at the component level first, and replacement is the last option, not the first.
Can EV batteries be repaired?
In many cases, yes. Packs are built from modules and supporting components, and a fault in one does not condemn the whole pack. We give you the repair options with pricing before any work.
How do you diagnose range loss?
We measure actual battery capacity and health with EV-specific diagnostic equipment, then separate normal degradation from a real fault. You get the data and a clear explanation, not a guess.
Do you service Tesla batteries?
Yes. Tesla high-voltage battery diagnostics and repair are a core specialty, including out-of-warranty vehicles.
Will this affect my warranty?
If your battery is still covered by the manufacturer warranty, we will tell you first and point you to the warranty claim. This service exists for vehicles outside that coverage.

What Our Customers Are Saying
★★★★★
Wonderful shop with outstanding service staff, even for a walk-in like me who needing some help with solving a charging problem. Karim went above and beyond around offering and providing help that quickly solved my problem and left me intrigued with EcoAuto.

Eco Auto is a much better service than Tesla Center service. They always take too long to schedule an appointment. I don't like Tesla service center, they do stupid little things like saying the coolant is low and I must make an appointment, which is silly. Eco Auto provides quick service within 5 minutes to put coolant in instead of scheduling an appointment. Eco Auto has friendly staff and I love them, I want to give them rewards. I will make good news for them to encourage people to use this place.
