Accurately Describing Car Problems:

When bringing your vehicle in for a specific problem it is very beneficial to have a detailed and accurate description of how and when the problem occurs. Describing car problems descriptively and accurately can be very helpful.  A good description of the problem can point us in the right direction and potentially reduce diagnostic time.

Example 1: If your car has an unusual noise – You might say – my car is making a noise and I want it fixed. Or you could say – my car has a metallic grinding coming from the left rear when I press the brake.

Example 2: Describing running problem. One description might be that my car runs badly and I am afraid to drive it.  A better description would be: My car runs rough intermittently, usually only when I first start it in the morning while it is idling. It feels like it wants to cut off. As soon as it warms up and I start driving it runs fine and is fine the rest of the day.

When your car starts acting up pay attention to what is happening.
Take note of any symptoms you observe:
