Battery boost: how we help
The 2018 Lexus RX and battery service: CarmaCars arranges a trusted shop, and never does the work itself. Lights left on overnight are the classic reason for a flat battery.
Before the shop sees your RX
Tell the shop about any warning light or sound you have noticed. Note the mileage on the odometer when you send the request. If you have the service history of your RX, have it ready for the shop. The powertrain here is the 3.5L 6-cylinder hybrid with all-wheel drive and an automatic (CVT).
The steps
Send the car's details and what it needs; we take it from there. We follow up until the shop has the car booked in. The shop quotes the job; you approve it before any work.
A car meanwhile
We collect the rental when your car is back. Keep moving with a rental while the shop has your car, by the day at our usual rates. We hand every car over in person, at your address or at our location.
Car care, briefly
Keep the fuel tank above a quarter in winter. Listen for new noises and mention them to the shop with as much detail as you can. Switch to winter tires before the first snow, and back in spring.
A short checklist
Ask whether the shop needs your keys, the wheel lock key or the spare. Ask whether the shop will check anything related while the car is there. Keep the invoice; it is part of the car's service history.
One more step
A request is free and gets a reply within one business day.
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.
