Battery boost: how we help
CarmaCars does not do mechanical work, but for battery service on the 2027 Tesla Model 3 we arrange a trusted shop. A battery that struggles in the cold is often near the end of its life.
Before the shop sees your Model 3
Your owner's manual lists the maintenance schedule for the Model 3. The shop sets its own price and time after it sees the car. If you have the service history of your Model 3, have it ready for the shop. The electric motor does the work, through a 1-speed automatic.
From request to repair
We tell you plainly if we do not know a shop for the job. The repair is between you and the shop; the rental is with us. You agree the price with the shop before any work starts.
A car while yours is in the shop
The rental is priced like any other on our site. We can have a rental ready the day your car goes in. We bring the car to your address in the Toronto area, or you collect it for free.
A short checklist
Ask how long the job should take, so you know how long to rent for. Ask the shop to call you before doing anything not on the estimate. If you want to see the old parts, ask for them back.
Between shop visits
Note the mileage when each service is done, so you know when the next is due. Wash the underside of the car in winter to clear road salt. Clear snow off the whole car, roof included, before you drive.
Let us know
Describe the problem, and we arrange a trusted shop.
Request battery boost
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.
