How Often Should I Have a Vehicle Diagnostics Test?

At a minimum, you should have a vehicle diagnostics test performed yearly. This way, you can reduce the likelihood of unexpected repairs.


Outside of the annual vehicle diagnostics, you should consider having the test performed anytime you detect something off, such as weird smells, strange sounds, your vehicle driving weirdly, or having odd engine performance.

Nonetheless, there is never a wrong time to have diagnostics performed by your trusted mechanics at Barney Brothers Off Road & Repair.

Diagnosing & Addressing Dashboard Indicator Lights
in Grand Junction, CO

One of the explicit ways your vehicle communicates with you is through dashboard indicators. One of them is the check engine light, which could be steady light or a blinking one.


A blinking check engine light is more serious. It typically means your engine is misfiring so severely that unburned fuel is being deposited into your exhaust system. If not addressed, this can cause extensive damage to your catalytic converter and lead to exponentially more expensive repairs.


Whether the check engine light is steady or flashing or another indicator is acting up, they should always be addressed. As soon as your vehicle triggers a warning light, it’s best to have vehicle diagnostics performed as quickly as possible.
