Your car’s a lot like your body in many ways. It works hard, keeps you going where you need to go, and occasionally needs a diagnostic checkup to ensure everything’s running as it should. That’s where an automotive diagnostic test comes in. But how often do you actually need to schedule one? Here’s the breakdown.
What Is an Automotive Diagnostic Test?
Before we get into the frequency, it’s helpful to quickly touch on the what and why. A diagnostic test is a digital health check for your car. Technicians use specialized software and tools to scan your car’s internal systems for issues or irregularities. The test checks the engine, brakes, transmission, exhaust system, and plenty of minor sensors you might not even know about.
When Should You Schedule a Test?
While there’s no one-size-fits-all rule, there are a few general guidelines you can follow.
1. For Regular Maintenance Checks
It’s good practice to schedule a diagnostic test at least once a year as part of your car’s overall maintenance routine. If you get overwhelmed by the idea of driving your car to a mechanic and waiting there for this service each year, you might consider mobile automotive diagnostic services, which come to you. Mobile services are particularly nice if your car is older or drives in harsh conditions, as these factors necessitate more frequent testing.
2. If You Notice Warning Signs
If any of your car’s warning lights come on or you’ve noticed unusual sounds, sluggish performance, or strange vibrations, don’t ignore the signs. Schedule a diagnostic test sooner rather than later.
3. Before Buying a Used Car
Planning to purchase a pre-owned vehicle? Arrange a diagnostic test to uncover issues the current owner may be hiding or not even know about. This can prevent costly surprises after you drive the car off the lot.
4. Before Long Road Trips
If you’re gearing up for a big road trip, a diagnostic test can help you hit the highway with peace of mind. You’ll know your car should be able to handle the miles without running into problems.
Final Thoughts
Ultimately, the exact science for how often you should schedule a diagnostic test depends on your car’s age, condition, and frequency of use. But don’t wait until a problem leaves you stranded. Regular diagnostics help you take care of your car better and prolong its lifespan. If you’re not sure where to start, talk to your local mechanic or auto shop about the best schedule for your specific make and model.
