Car diagnostics: how we help
Need a diagnostic check for your 2018 Genesis G90? We do not do mechanical work, but we arrange it with a trusted shop and keep you driving meanwhile. A warning light is the car asking for a diagnostic scan; the code tells the shop where to look.
Before the shop sees your G90
If you have the service history of your G90, have it ready for the shop. A photo of the dashboard warning light helps the shop prepare. Bring the owner's manual or service records if you have them. The powertrain here is the 3.3L 6-cylinder turbo with all-wheel drive and an 8-speed automatic.
What we arrange
You approve the shop's quote before any work. We follow up until the shop has the car booked in. Your request goes to a person, who arranges a trusted shop or gives you its name.
A rental while you wait
A rental keeps your week on track during the repair. Pick a car that suits your week from our fleet. We bring the car to your address in the Toronto area, or you collect it for free.
Before the shop starts
Ask what warranty the shop gives on its parts and labour. Ask the shop to explain the repair in plain words before you agree. Ask whether the parts are new, rebuilt or used.
Between shop visits
Switch to winter tires before the first snow, and back in spring. Use the grade of fuel your owner's manual calls for. Top up the washer fluid with a winter mix in the cold months.
One more step
Tell us the job and the car, and a person replies.
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.
