Car diagnostics: how we help
Car diagnostics for your 2003 Lexus GS: arranged with a trusted shop, never done by CarmaCars, with a rental if you need one. A steady check engine light needs a check soon; a flashing one means pull over safely and get help.
Your car, your notes
Note the mileage on the odometer when you send the request. The shop may ask for the VIN to order the right parts. A photo of the dashboard warning light helps the shop prepare. The engine is the 3.0L 6-cylinder, with rear-wheel drive and a 5-speed automatic.
How the request works
The repair is between you and the shop; the rental is with us. We keep you posted until the car is booked in. You agree everything with the shop before work begins.
Driving while yours is at the shop
Keep the rental as long as the repair takes. Rent for as long as the job takes, by the day or the week. Delivery covers the Toronto area, priced by distance in your offer; pickup from us is free.
Talking to the shop
If you want to see the old parts, ask for them back. Ask whether the estimate includes tax and shop supplies. Ask whether the shop needs your keys, the wheel lock key or the spare.
Car care, briefly
Check that all lights work every few weeks. Clear snow off the whole car, roof included, before you drive. Keep the fuel tank above a quarter in winter.
Talk to a person
Ask us, and we tell you whether we can arrange it.
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.
