A: The cost of a diagnostic test on a car can range from $120 to $250, depending on the complexity of the issue. This fee pays for professional technicians to diagnose any problems with your vehicle. Most service centers require payment upfront before beginning the diagnostic process. Many shops offer discounts for multiple diagnostic tests purchased at once. Be sure to reach out and ask about any offers available. Generally, it’s best to keep up with routine car maintenance rather than waiting until an issue arises, which could save you money in the long run.

A: Diagnostic tests for automobiles are helpful for a number of different reasons. Diagnostic tests for automobiles enable drivers to identify potential problems before they escalate into costly emergencies, which ultimately saves drivers money. In addition, identifying errors in their early stages, prior to their becoming more serious, has the potential to save your life as well as the lives of others.

 The check engine light has come on in your car, but understanding why can be confusing and overwhelming. While car trouble codes may appear to provide answers, it’s important to realize that just reading diagnostics codes is not a diagnostic – and that you should have an expert take a look at the car soon. This is because the check engine light signifies that there is a fault in the car system; without taking the car in and having a professional running tests and examining potential issues, you won’t be able to identify just what needs fixing. Don’t wait too long – get a diagnostic from an expert as soon as possible!



The California Vehicle Code (Section 580) describes a “specially constructed vehicle” as a vehicle which is built for private use, not for resale, and is not constructed by a licensed manufacturer or remanufacturer. A specially constructed vehicle may be built from (1) a kit; (2) new or used, or a combination of new and used, parts; or (3) a vehicle reported for dismantling, as required by Section 5500 or 11520, which, when reconstructed, does not resemble the original make of the vehicle dismantled. A specially constructed vehicle is not a vehicle which has been repaired or restored to its original design by replacing parts.

A: When your car doesn’t turn on it can be really frustrating! The first thing most people think of is the battery, and while that may be the cause, it could also be something related to the fuel system, ignition system or immobilizer system.

Doing this will not only help you get a correct diagnosis but can also help prevent any unnecessary repairs so you don’t have to spend more money than necessary!

A: Taking care of your car is a serious responsibility, and nothing is more important than regularly changing your oil.
