Car diagnostics for the 2018 Mazda 3

Your 3 and the shop
A photo of the dashboard warning light helps the shop prepare. Say whether the car is drivable; it changes how it gets to the shop. The shop may ask for the VIN to order the right parts. Its 2.0L 4-cylinder drives through a 6-speed automatic.
What CarmaCars does here
We tell you plainly if we do not know a shop for the job. We pass your request to a trusted shop or give you its name. You agree the price with the shop before any work starts.
Driving while yours is at the shop
We can have a rental ready the day your car goes in. Keep moving with a rental while the shop has your car, by the day at our usual rates. Delivery is priced by distance in your offer, and pickup from us is free.
Questions to ask the shop
If a warning light was the reason, ask what the code was and what fixed it. Ask for a written estimate before any work starts. Ask whether the shop needs your keys, the wheel lock key or the spare.
Good habits for your car
Switch to winter tires before the first snow, and back in spring. Top up the washer fluid with a winter mix in the cold months. Wash the underside of the car in winter to clear road salt.
When you know your dates
A request is free and gets a reply within one business day.
