Modern vehicles are built with advanced technology that makes them more reliable, efficient, and safer than ever before.

At FastLane Automotive, we provide expert Car Diagnostics in Orlando & Sanford, FL, helping drivers identify issues quickly and accurately—whether it’s a glowing check engine light or an unusual performance issue.
Our ASE-certified technicians use state-of-the-art scanners and hands-on experience to pinpoint the exact cause of your car troubles. Instead of guessing, we give you clear answers so you can make confident repair decisions.
Why Car Diagnostics Matter
Every car today is equipped with an onboard computer system that monitors and regulates essential functions. This includes your engine, transmission, emissions, safety systems, and more. When one of these systems detects a problem, your vehicle stores a trouble code and often illuminates a check engine light on the dashboard.
A diagnostic scan reads these trouble codes and translates them into actionable information. Without proper testing, small issues can turn into major repairs, costing you more time and money down the road.
Signs You Need Car Diagnostic Testing
While the check engine light is the most obvious sign, there are other indicators that your car may need diagnostics:
-
Sudden drop in fuel efficiency
-
Rough idling or engine misfires
-
Strange noises while driving or idling
-
Warning lights for ABS, airbags, or transmission
-
Smoke from the exhaust
-
Difficulty starting your car
-
Reduced power or hesitation when accelerating
If you’re experiencing any of these issues, it’s time to schedule a car diagnostic test at FastLane Automotive.
