Arranging the work for the CT6
For a diagnostic check on your 2016 Cadillac CT6, we arrange a trusted shop; CarmaCars does not do the work. A steady check engine light needs a check soon; a flashing one means pull over safely and get help.
Before the shop sees your CT6
Bring the owner's manual or service records if you have them. A photo of the dashboard warning light helps the shop prepare. The shop may ask for the VIN to order the right parts. The 2.0L 4-cylinder turbo is what moves it, with rear-wheel drive.
Our part and the shop's part
You agree the price with the shop before any work starts. We pass your request to a trusted shop or give you its name. We do not set the shop's price or promise a date.
A car meanwhile
We deliver the rental to you and collect it when your car is ready. A rental from us keeps you moving while the shop has your car. Delivery covers the Toronto area, priced by distance in your offer; pickup from us is free.
Between shop visits
Have the battery tested before winter if it is more than a few years old. Keep the fuel tank above a quarter in winter. Wash the underside of the car in winter to clear road salt.
Before the shop starts
If you want to see the old parts, ask for them back. Ask the shop to call you before doing anything not on the estimate. Ask whether the shop will check anything related while the car is there.
Ready when you are
Send the car's details and the job, and we take the next step.
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.
