Is the Hybrid Battery Actually Failing?
There are a lot of older Priuses still on the road around Stony Brook and Setauket, and sooner or later someone tells the owner the hybrid battery is going. That is a question with a real answer, not an opinion.
We read hybrid battery state of health and the individual cell block voltages with Toyota factory diagnostic software. A pack that is genuinely failing shows a spread between blocks. A healthy pack with an unrelated fault does not — and plenty of "dying battery" cars turn out to have something far cheaper wrong with them.
On a car that is a decade or more old, that is the difference between a repair worth doing and a car worth letting go. Either way you should know before anyone quotes you a battery.
Hybrid Battery Health
State of health plus individual cell block readings — the data that settles the question.
Factory-Level Codes
Manufacturer-specific faults across engine, transmission, ABS, airbag and body modules.
Active Testing
Command components directly to isolate a fault instead of replacing parts to find out.
An Honest Answer
If an older car is not worth the repair, we will say so. You decide on real information.

Toyota & Lexus Specialists
Most independent shops diagnose a Lexus with the same generic code reader they use on everything else, which is why you sometimes pay for a part that was never the problem. We run Toyota and Lexus factory diagnostic software at your car — manufacturer-specific codes across every module, active component testing, and the resets and relearns a generic tool cannot perform after a repair.
BMW or Mercedes? Those go to our partner shops with the right factory tooling — we are adding that capability in-house shortly.
Everything Else, At Your House

Pads, rotors, calipers and brake lines, done in your driveway.
Automotive Electrical

Shocks, struts, springs and control arms for a ride that stops bouncing.

Conventional, synthetic and high-mileage, without the waiting room.
Why Three Village Drivers Use a Mobile Mechanic
The cost of a repair around here is rarely the problem — the disruption is. Dropping a car at a shop means arranging a ride, losing a morning, and arranging another ride to collect it. We come to the house instead and the car never leaves the driveway.
Proper diagnosis before parts. With factory software we can tell you what actually failed rather than working through likely suspects at your expense. On older Toyotas and Lexuses in particular, that usually costs less overall than the cheap diagnosis does.

Common Questions
Is my Prius hybrid battery actually failing?
Answerable with data, not opinion. We read state of health and individual cell block voltages with Toyota factory software. A failing pack shows a spread between blocks; a healthy one with an unrelated fault does not.
Do you come to Stony Brook and Setauket?
Yes — Stony Brook, Setauket, East Setauket, Old Field, Poquott, Head of the Harbor, Nissequogue and St. James are all in normal range.
Do you service Lexus?
Yes, and it's a strength. Lexus factory diagnostic software means manufacturer-specific codes across every module, not the handful a basic scanner reports.
Is it worth fixing an older car?
Sometimes the honest answer is no, and we'll tell you. Diagnosing properly first means you decide on real information instead of a guess.
Do I need to be home during the repair?
Only to let us start and to settle up. Most jobs happen in your driveway while you get on with your day.
