Car diagnostics: how we help
For a diagnostic check on your Hummer H3, we arrange a trusted shop; CarmaCars does not do the work. A warning light is the car asking for a diagnostic scan; the code tells the shop where to look.
About your H3
If you have the service history of your H3, have it ready for the shop. Tell the shop about any warning light or sound you have noticed. Your owner's manual lists the maintenance schedule for the H3.
What CarmaCars does here
We pass your request to a trusted shop or give you its name. We keep you posted until the car is booked in. Send a request with the car and what it needs; a person replies within one business day and arranges it with a trusted shop or recommends one.
A car meanwhile
We bring the rental to you and collect it afterwards. We collect the rental when your car is back. Pick it up from us for free, or have it brought to you.
Between shop visits
Listen for new noises and mention them to the shop with as much detail as you can. Keep a record of every service; it helps the shop and adds value when you sell. Check the tire pressure once a month, when the tires are cold.
Talking to the shop
Ask whether the parts are new, rebuilt or used. Ask when the car will be ready and how the shop will tell you. If the car must stay overnight, ask where it will be kept.
Questions first?
One request: the job, the car, and whether you need a rental meanwhile.
Request car diagnostics
Tell us when suits you. A person replies within one business day and arranges it with a trusted shop or recommends one; the shop sets its own price and time.
