24/7Dallas, TXUnder 30 min
We load-test the 12V, hunt parasitic draw, read stored fault codes and report pack state of health in writing. The Colony calls are typically on scene in 25 to 40 minutes.
Grandscape and Austin Ranch dominate. Grandscape produces lockouts and dead 12V calls from long visits; Austin Ranch produces them from cars parked in decks for days. When the problem is on-site EV battery diagnostics, The Colony drivers do not need a tow truck and a day without their car — they need someone who can fix it in the spot the car stopped in.
Drivers replace a 12V twice in a year and assume they got two bad batteries. Usually something is draining it and nobody looked. We load-test the 12V, hunt parasitic draw, read stored fault codes and report pack state of health in writing.
We run SH-121, the Dallas North Tollway and FM-423 and get called to Grandscape and the Nebraska Furniture Mart lots, Austin Ranch apartment decks and Lewisville Lake shoreline roads constantly, so a The Colony dispatch is not a technician following a map for the first time. Typical arrival window is 25 to 40 minutes, 24 hours a day, and you get a flat quote before a truck is assigned. Call or text (945) 383-4744.
Typical time on scene: 45 to 75 minutes.
Load-test the 12V properly rather than reading a resting voltage that tells you almost nothing.
Measure parasitic draw after the modules have gone to sleep, and isolate the circuit that is not sleeping.
Pull stored codes and pack state of health, and hand you the numbers in writing so a shop cannot hand-wave them.
Young renters in Austin Ranch and families along 423 — a high share of first-time EV owners in apartment parking with no dedicated charger.
The locations repeat. Most of our The Colony EV battery diagnostics calls come from Grandscape and the Nebraska Furniture Mart lots, Austin Ranch apartment decks, Lewisville Lake shoreline roads, Stewart Peninsula and the 423 retail corridor, plus the shoulder and ramp work along SH-121, the Dallas North Tollway, FM-423 and Main Street. An untraced parasitic draw will kill a brand-new battery just as reliably as the old one, usually in a garage where it is least convenient.
Austin Ranch decks are numbered inconsistently and have several unmarked entrances. We ask for the building number, not just the address.
Every The Colony call follows the same sequence, whether you are in a driveway in a quiet subdivision or on a shoulder with traffic going past at seventy. Time on scene for on-site EV battery diagnostics is typically 45 to 75 minutes, on top of the 25 to 40 minutes it takes us to reach you.
We load-test the 12V, hunt parasitic draw, read stored fault codes and report pack state of health in writing. Nothing gets improvised, and nothing gets torqued by feel — every wheel that comes off a car in The Colony goes back on to the manufacturer's figure.
A general tow operator solves one problem: moving the vehicle somewhere else. That is the wrong answer for on-site EV battery diagnostics, because repeat dead batteries, phantom warnings and range that dropped off a cliff all have causes, and a parts swap is not a diagnosis — and the repair itself takes less time than the tow would.
We are a private, Texas-owned EV roadside company operating since 2014, with EV-rated jacks and pucks, EV-specific tooling and technicians who work on electric vehicles all day. The Colony sits inside our core Denton County service area, dispatched from our Dallas-area base, which is how the 25 to 40 minutes window is realistic rather than aspirational.
Pricing is flat and quoted on the first call. Payment is settled on scene by card, Apple Pay, Google Pay, Zelle, Venmo or CashApp, and you get a digital receipt by text — which matters if you are expensing it or filing with an insurer.
Same trucks, same 25 to 40 minutes window. Pick the problem you actually have.
