Your car's electrical system controls everything — starting, charging, lighting, safety sensors, and more. When something fails, you need a shop that diagnoses the real problem, not one that replaces parts hoping something sticks.
Serving Matthews, Indian Trail, Stallings & the Charlotte area
Most electrical problems diagnosed the same day.
Electrical repairs vary widely depending on the root cause. Here’s a realistic guide based on common jobs — parts and labor included. We always provide a detailed, no-obligation written quote after inspection. No surprises.
Ranges are typical for domestic and most import vehicles. European or luxury vehicles may be higher. Exact cost depends on the fault found at inspection.
Complete Auto Electrical Care — Batteries, Alternators, Wiring & Beyond
We test your battery’s cold cranking amps and charging health before recommending replacement — so you’re never sold a battery you don’t need.
A failing alternator can strand you without warning. We test the full charging system, not just the part that looks bad, before recommending any repair.
Click when you turn the key? Nothing at all? We pinpoint whether it’s the starter, solenoid, or ignition circuit — and fix the actual cause.
Shorts, broken grounds, and corroded wiring are the hardest faults to find. We use professional-grade circuit testing equipment to trace faults without guesswork.
Blown fuses that keep returning are a symptom, not the problem. We find the underlying short causing the failure before replacing any components.
We read fault codes across all modules — not just powertrain — so you get the complete picture of what’s happening in your vehicle.
Intermittent faults in accessories are frustrating. We trace the entire circuit — switches, motors, regulators, wiring — and fix it properly the first time.
Modern vehicles have dozens of control modules. We carry factory-level software to diagnose, reprogram, or replace modules correctly across all makes.
Battery dying overnight with no obvious cause? We run a systematic draw test to find exactly which circuit is draining power — one of the most misdiagnosed problems.
Electrical issues rarely fix themselves — and some can leave you stranded or cause further damage if ignored.
Electrical problems often produce multiple symptoms that seem unrelated. If something feels “off” but you can’t pinpoint it, a full diagnostic is the fastest path to a clear answer.
“They towed our car to the shop and found the problem same day. Issue was fixed and we were our employee was on the way same day.”
— Regiistek Management
“I came in with a strange noise in my suspension that no other mechanic could figure out — four different shops tried and failed. But here, they diagnosed the issue quickly and fixed it…”
— Anastasiia D
“They quickly performed a diagnostic, identified the issue, and found the replacement part right away. They even ordered it themselves, and the next day my car was ready.”

Dealer-level diagnostic tools and circuit testers — not generic code readers from the parts store.
We don’t replace parts hoping it fixes the issue. We test until we know exactly what's wrong.
You approve everything before we start. No surprise invoices — ever.
We document everything with photos so you can clearly see the issue.
We stand behind our repairs. Ask us about specific coverage when you bring your car in.
Got Questions?
The questions Matthews drivers ask before bringing their car in — answered honestly.
This is a parasitic drain — something is drawing power when the car is off. Common causes: a faulty relay, a module that won't sleep, or a short. A proper amperage test and circuit isolation will find it.
Standard diagnostics take 1–2 hours. Complex or intermittent faults — like a short that only appears after rain — can take longer. We'll give you an honest time estimate after the initial scan.
Potentially not for long. If the alternator fails while driving, your battery drains within 30–60 minutes and the car loses power. Call us before driving far — it can leave you stranded.
Yes. We service all makes including European imports and carry manufacturer-specific diagnostic software that many generic shops simply cannot access.
Yes. Our diagnostic fee starts at $95. If you proceed with the repair, that fee is credited toward your total. We'll always share the estimate before any work begins — no pressure.
A battery test checks if it holds a charge (cold cranking amps). An alternator test checks whether it's producing the correct voltage — 13.5 to 14.5V — to keep the battery charged while driving. Both take just minutes.
Electrical problems tend to be random or intermittent — flickering lights, slow cranking, accessories cutting out, warning lights with no obvious mechanical cause. If symptoms feel unpredictable, a diagnostic is the fastest answer.
Yes. Warranty terms vary by part and repair type. Ask us for specific coverage when you come in — we'll explain exactly what's covered and for how long before you commit to anything.
Getting Started
Call (704) 635-1813 or fill out our online form. Even "it's just acting weird" is enough — we'll help you figure it out.
Share your make, model, year, and what you've noticed. More detail helps us prepare before you even arrive.
We'll book a time that works for you. Same-day and next-day appointments are often available for electrical issues.
After our diagnostic, you receive a clear written breakdown of what we found and what it costs — before we touch anything.
Don't let an electrical problem turn into a bigger headache. Most issues are diagnosed and resolved same-day or within 24 hours at Prime Motors.
