What Moves the Price
Labor rates: independent shops typically charge $80–$150 per hour, dealerships $120–$200. Parts choice: OEM parts cost more than quality aftermarket equivalents. Vehicle access: a part buried in the engine bay takes more labor hours than an easily reached one.
When to Book
diagnosis-heavy labor where the right shop saves real money. If you're seeing symptoms — noises, warning lights, changes in how the car drives — book an inspection early: catching a problem at the symptom stage is almost always cheaper than at the breakdown stage.
Frequently Asked Questions
Why is electrical diagnosis billed by the hour?
Faults hide — a parasitic draw or intermittent short can take hours to trace. Good shops quote a diagnosis window before diving in.
How long should a car battery last?
3–5 years in most climates; heat is harder on batteries than cold. Many shops test batteries free and print the result.
My battery light is on but the car runs fine — urgent?
The car is running on battery alone. Once it drains, the car dies. Drive less, shut off accessories and get the charging system tested immediately.
