RODA SERVICE
Diagnose Electrical Concern
Modern vehicles rely on complex electrical systems to power everything from starting and charging to lights, windows, and sensors. When something stops working — or works intermittently — the cause can be a bad connection, a blown fuse, or a failing control module.

Our goal is full transparency — As long as any recommendation is approved, we will waive the $100 diagnostic fee and only charge you for the work done. We also offer price matching if you have a better quote from a different shop.
We’ll always provide an exact quote after diagnosis — no surprises, ever.
When You Need This
Electrical problems can cause anything from small annoyances to major system failures — here’s when to schedule a diagnostic.

Battery Keeps Dying or Losing Charge
Often caused by parasitic draws, failing alternators, or control modules staying powered after shutdown.
Lights, Windows, or Accessories Stop Working
A blown fuse, faulty relay, or wiring fault can interrupt power to entire circuits or individual components.
Warning Lights or Random Electrical Glitches
Loose grounds, corroded connectors, or voltage drops can trigger multiple warning lights or erratic operation.
Intermittent Power Loss or Starting Trouble
Unstable electrical flow or worn ignition components can cause inconsistent starts or sudden system shutdowns.

⚠️ What happens if you skip it? ⚠️
Unresolved electrical problems can lead to complete system failure, battery drain, or safety issues like loss of lighting or power steering assist. Early diagnosis prevents damage to sensitive electronics and avoids costly replacements later.
What It Could Be
Electrical concerns can come from several potential sources — our diagnostic process isolates which one is to blame.
• Blown Fuse or Relay Failure
Prevents current from reaching certain components.
• Corroded or Loose Connectors
Causes intermittent function or voltage drop across the system.
• Weak Battery or Failing Alternator
Creates low-voltage conditions affecting multiple modules.
• Faulty Control Module or Sensor
Sends incorrect signals or shuts down related systems.
• Parasitic Draw
A system that stays on after shutdown, draining the battery overnight.
How This is Done
We use professional diagnostic tools and step-by-step testing to pinpoint the root cause precisely.
1. Verify Symptoms
Recreate and document the electrical issue.
2. Scan Vehicle Systems
Read and analyze trouble codes from all control modules.
3. Check Power & Ground Integrity
Test for voltage drops, poor grounds, and continuity issues.
4. Inspect Fuses, Relays & Wiring
Identify visible damage, corrosion, or short circuits.
5. Test Component Function
Confirm operation of sensors, switches, and accessories.
6. Review Results & Explain Findings
Present a clear summary with repair options and pricing.

Rated 5-stars by hundreds of DC-area drivers
“Roda was a great service. I hit a pothole and had a blow out. They came and picked the car up downtown, fixed it, and dropped it back at my house. I'll definitely check them out again.”
- DAVE W.Is the diagnostic really free?
Yes — if you approve the recommended repair or service, we waive the $100 diagnostic fee.
Can an electrical issue drain my battery?
Yes — a component staying powered after shutdown can drain the battery overnight.
Why do my lights or wipers work intermittently?
Likely due to a loose connector, damaged wire, or failing relay — we’ll pinpoint exactly where.
Will this service find the problem even if it’s intermittent?
In most cases, yes. If it’s inconsistent, we can use data logging or repeated testing to capture it.
Can you diagnose hybrid or EV systems?
Yes — our technicians are trained to safely handle high-voltage and advanced vehicle electronics.
What does the Roda warranty cover?
All repairs performed after diagnosis are covered by our Roda 12-month / 12,000-mile warranty, including both parts and labor for complete peace of mind.
