Engine repair: how we help
For engine work on the 2020 Genesis G80, CarmaCars arranges a trusted shop and rents you a car while yours is in. An engine that runs rough, smokes or overheats needs a look soon.
Before the shop sees your G80
Note the mileage on the odometer when you send the request. The shop may ask for the VIN to order the right parts. Tell the shop the year, the trim and the engine: the 3.8L 6-cylinder. Power comes from the 3.8L 6-cylinder, driving through an 8-speed automatic.
The steps
We can deliver a rental to you while your car is at the shop. Your request goes to a person, who arranges a trusted shop or gives you its name. We tell you plainly if we do not know a shop for the job.
No car? Rent one meanwhile
A rental keeps your week on track during the repair. We bring the rental to you and collect it afterwards. The handover is in person, at your address or at our location.
Getting a clear quote
Ask whether the quote includes both parts and labour. Ask whether the estimate includes tax and shop supplies. Ask how the shop will contact you if it finds something unexpected.
Good habits for your car
Replace wiper blades when they streak; it matters in rain and snow. Look at the tire tread before long trips. Have the battery tested before winter if it is more than a few years old.
Send a request
Ask, and we tell you plainly what we can arrange.
Request engine repair
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.
