Battery boost: how we help
For battery service on your 2015 BMW i8, we arrange a trusted shop; CarmaCars does not do the work. Lights left on overnight are the classic reason for a flat battery.
Details the shop needs
Tell the shop the year, the trim and the engine: the 1.5L 3-cylinder turbo hybrid. Mention the trim and engine in your request; parts differ between them. Your owner's manual lists the maintenance schedule for the i8. It uses the 1.5L 3-cylinder turbo hybrid and all-wheel drive.
The steps
The shop quotes the job; you approve it before any work. We do not set the shop's price or promise a date. We keep you posted until the car is booked in.
A car while yours is in the shop
The rental is priced like any other on our site. If the repair runs long, keep the rental longer. Delivery starts at $75 plus distance; collecting the car yourself is free.
A short checklist
Ask when the car will be ready and how the shop will tell you. Ask how long the job should take, so you know how long to rent for. If you want to see the old parts, ask for them back.
Car care, briefly
Look at the tire tread before long trips. Replace wiper blades when they streak; it matters in rain and snow. Clear snow off the whole car, roof included, before you drive.
Want a price?
Need the work and a rental? One request covers both.
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.
