Car battery replacement: how we help
Your 2018 Lexus RX needs battery service? We arrange a trusted shop; CarmaCars does not do the work. Lights left on overnight are the classic reason for a flat battery.
About your RX
Note the mileage on the odometer when you send the request. Mention the trim and engine in your request; parts differ between them. Your owner's manual lists the maintenance schedule for the RX. The 3.5L 6-cylinder hybrid, paired with an automatic (CVT), drives it.
What CarmaCars does here
The repair is between you and the shop; the rental is with us. The shop sets the price and the time after seeing the car. We pass your request to a trusted shop or give you its name.
A rental while you wait
The rental is priced like any other on our site. Rent for as long as the job takes, by the day or the week. We meet you with the car at the time we confirm, at your address or ours.
Good habits for your car
Check the tire pressure once a month, when the tires are cold. Note the mileage when each service is done, so you know when the next is due. Have the battery tested before winter if it is more than a few years old.
Questions to ask the shop
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. Ask when the car will be ready and how the shop will tell you.
Ready to ask?
Send the car's details and the job, and we take the next step.
