Car battery replacement: how we help
Need battery service for your 2018 Ford Flex? We do not do mechanical work, but we arrange it with a trusted shop and keep you driving meanwhile. Lights left on overnight are the classic reason for a flat battery.
Your Flex and the shop
If you have the service history of your Flex, have it ready for the shop. Bring the owner's manual or service records if you have them. Tell the shop about any warning light or sound you have noticed. Its 3.5L 6-cylinder drives through a 6-speed automatic.
What CarmaCars does here
The repair is between you and the shop; the rental is with us. Tell us when suits you, and whether the car can be driven. You agree everything with the shop before work begins.
Your rental while you wait
We can have a rental ready the day your car goes in. The rental is priced like any other on our site. Your offer shows any delivery fee before you pay.
A short checklist
Ask whether the shop needs your keys, the wheel lock key or the spare. Ask for the work to be listed line by line on the invoice. Ask the shop to call you before doing anything not on the estimate.
Good habits for your car
Keep the spare, the jack and the wheel lock key where you can find them. Follow the maintenance schedule in your owner's manual, by time or distance. Replace wiper blades when they streak; it matters in rain and snow.
Make a request
Ask in your request, and we tell you plainly what we can arrange.
