Carolyn CoquilletteCo-Founder and CEO
Carolyn opened Luscious Garage in a SOMA warehouse in 2007, when hybrids were new and most shops would not touch them. The shop software she had built there became Shop-Ware, which she founded in 2013.

All 35 topicsThree shops, three owners. Independent hybrid and EV specialists in three cities, each run by the person who built it.
Travis DeckerOwner, ASE Master Technician
Travis started Atomic in 2005 after years of fixing Saabs for friends, and turned it into a hybrid shop when the cars changed. He still does a lot of the diagnosis, and answers a lot of the texts.
Eric SumpterOwner
Eric left about twenty years in technology in 2008 to build the shop, and its first hybrid work was reconditioning Prius battery packs. Other Denver repair shops send it diagnosis and sublet work.
How they connect. Opened years apart, all three keep their repair orders in Shop-Ware, and the hub counts them as one network.

Open, before the records we countRepair orders counted, from Shop-Ware
Independently owned.
Three hybrid and EV specialists, each independently owned and still run by its founder.
All on Shop-Ware.
All three keep their repair orders in Shop-Ware, which began as Carolyn's own shop software at Luscious Garage.
Counted one way.
Every figure is distinct repair orders, counted by the same rules at each shop, so the three add up to one network.

- Bolt recall packs: what we check after the swapA huge number of Bolts got a new pack under recall. If you are buying one, or you have one, there are a few specific things worth confirming.
- Leaf capacity loss: reading the battery bars honestlyThe Leaf's capacity bars are a blunt instrument, and the early cars had no thermal management to protect the pack. Here is how to read what the car is telling you.
- Why Tesla brakes rust before they wear, and what to do about itRegeneration does nearly all the slowing, so Tesla pads outlast the car and the rotors quietly corrode instead. In a coastal city that happens faster than most owners expect.
- Model 3 12V: when to move to the lithium batteryThe most common Tesla call Earthling gets is not the big battery. It is the small one, and it gives about a week of warning.

- 2008 Toyota Prius P0A0F P3193: Wouldn’t MovePrius P0A0F P3193 with no drive: this 2008 was simply out of fuel, three bars still showing on the gauge. One gallon fixed it - here's the diagnosis.
- Toyota P0441 & P0455 EVAP Codes ExplainedP0441 and P0455 on a Toyota? What these EVAP codes mean, why it's usually the gas cap, and when it's something more serious - from Portland's Toyota specialists.
- Gen 2 Prius Fuel Tank Bladder: Why the Gauge Lies and the Tank Won't FillGen 2 Prius won't take a full tank, or the gauge reads wrong? Why the tank has a bladder, what the inclinometer reset really does, and how to live with it using the trip odometer.
- Mice in Your Toyota! Prevention, Detection, and SolutionsMice in Toyota Prius damage starts with chewed wiring and can run into thousands. Atomic Auto in Portland explains the signs, prevention, and repair costs.
- Mile Hybrid Automotivemilehybrid.evpartners.ai
- Early Tesla Model S: what we see on the 2012 to 2016 carsTesla is a small part of what we do, and we keep it honest. The early Model S comes to us for its cooling system, its 12V battery and its brakes, and independent service does not void its warranty.
- The hybrid battery fan: the vent most owners never knew they hadMost Toyota, Lexus, Ford and Honda hybrids cool their battery with air from the cabin. When the vent and fan clog, the pack runs hot and ages early. It is one of the cheapest things to keep right.
- The first Prius, 2001 to 2003: keeping the original on the roadThe first Prius sold in America is still on Denver's roads, and we still see them. They need what any twenty-year-old hybrid needs, and a shop that remembers how they work.
- Buying a used hybrid: what we check before you buyA used hybrid can be a very good buy. The battery is the part people worry about, but it is not the only thing worth checking, and a test before you buy is far cheaper than a surprise after.

Questions people ask. Short answers about the shops, the numbers and the network.
What is EV Partners?
A network of independent hybrid and EV repair shops. Each shop stays independently owned. Together we publish the EV Repair Hub, reports written from the shops' own repair orders and reviewed by a person before they publish.
Does EV Partners fix cars?
No. The shops do: Earthling Automotive in San Francisco, Atomic Auto in Portland and Mile Hybrid Automotive in Denver. Call the one nearest you.
- Earthling AutomotiveSan Francisco, CA(415) 875-9030
- Atomic AutoPortland, OR503-969-3134
- Mile Hybrid AutomotiveDenver, CO(720) 445-4357
Where do the numbers come from?
From the shops' own Shop-Ware records: 36,158 repair orders on hybrid and EV work so far. Each one is a real job a shop wrote up, counted once.
Are the numbers real and current?
Yes. No figure on this site is typed. Each one is counted from the records when the page is served, and the records sync every night. The latest sync is from October 2026.
Is customer data shared?
No. Only counts leave a shop: the make, model and model year, the system worked on, fault codes and the quarter the work closed. No names, phone numbers, addresses, VINs or plates.
Which cars do the shops work on?
Mostly hybrids, and mostly Toyotas: 73 percent of the repair orders we count are on a Toyota, most of them a Prius. EV work, Teslas included, is real but a much smaller share.
