Arranging the work for the Highlander
For a diagnostic check on the 2018 Toyota Highlander, CarmaCars arranges it with a trusted shop or connects you with one; the work is done by the shop, not by CarmaCars. A warning light is the car asking for a diagnostic scan; the code tells the shop where to look.
Your Highlander and the shop
The shop may ask for the VIN to order the right parts. Bring the owner's manual or service records if you have them. Tell the shop the year, the trim and the engine: the 3.5L 6-cylinder hybrid. Power: the 3.5L 6-cylinder hybrid; drive: all-wheel drive.
What CarmaCars does here
The repair is between you and the shop; the rental is with us. Send the car's details and what it needs; we take it from there. You agree everything with the shop before work begins.
No car? Rent one meanwhile
Keep the rental as long as the repair takes. Rent by the day while the shop has your car. Your offer shows the delivery fee if you want the car brought to you.
Talking to the shop
Ask how the shop takes payment before you pick the car up. Ask if the shop needs the car for a full day or only a few hours. Ask what warranty the shop gives on its parts and labour.
Good habits for your car
Switch to winter tires before the first snow, and back in spring. Keep the spare, the jack and the wheel lock key where you can find them. Have the cabin air filter changed on the maker's schedule.
