Battery boost: how we help
CarmaCars does not do mechanical work. For battery service on the 2018 Subaru Forester, we connect you with a trusted shop. A slow crank on a cold morning is often the first sign of a tired battery.
About your Forester
If you have the service history of your Forester, have it ready for the shop. A photo of the dashboard warning light helps the shop prepare. Tell the shop the year, the trim and the engine: the 2.5L 4-cylinder. It is powered by the 2.5L 4-cylinder, with all-wheel drive.
How the request works
You approve the shop's quote before any work. We keep you posted until the car is booked in. We tell you plainly if we do not know a shop for the job.
No car? Rent one meanwhile
The rental is priced like any other on our site. Rent for as long as the job takes, by the day or the week. Delivery starts at $75 plus distance; collecting the car yourself is free.
Talking to the shop
Ask for the work to be listed line by line on the invoice. Ask for a written estimate before any work starts. If you want to see the old parts, ask for them back.
Good habits for your car
If the car pulls to one side, ask the shop to check the alignment and the tires. Do not ignore a warning light; an early check often costs less than a late repair. Note the mileage when each service is done, so you know when the next is due.
