Arranging the work for the G80
CarmaCars does not do this work itself. For a diagnostic check on the 2020 Genesis G80, we arrange it with a trusted shop or connect you with one. A warning light is the car asking for a diagnostic scan; the code tells the shop where to look.
About your G80
If you have the service history of your G80, have it ready for the shop. The shop may ask for the VIN to order the right parts. The shop sets its own price and time after it sees the car. The 3.8L 6-cylinder with rear-wheel drive is the powertrain to look at.
How the request works
Tell us when suits you, and whether the car can be driven. Your request goes to a person, who arranges a trusted shop or gives you its name. We follow up until the shop has the car booked in.
A car meanwhile
We can have a rental ready the day your car goes in. A rental from us keeps you moving while the shop has your car. Your offer shows the delivery fee if you want the car brought to you.
A short checklist
Ask whether the shop will check anything related while the car is there. Ask the shop to call you before doing anything not on the estimate. Ask whether the parts are new, rebuilt or used.
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. Note the mileage when each service is done, so you know when the next is due.
