I have a 2021 GTPE. I changed both the 12 volt battery and replaced the brake fluid at 36 months. It cost $417 and I paid for it with points. I plan to have the car at the next 36 month interval and change both again.have a 22 premium er rwd . 2 yrs 9 months old got the 12 volt warning MSG. Made an appointment to have lvb checked out and was wondering while at dealer what forums thoughts are about brake fluid change.
There are a lot of people who have never done a brake fluid flush. Some people are just lucky. Other's had master cylinders, brake wheel cylinders, calipers or brake hoses fail and the fluid was changed with that repair. (Failures were quite possibly due to contaminated fluid)I had a Ford Expedition for 24 years and never changed the brake fluid.
