Brake Disc Pads problems of the 2009 Toyota Highlander

I have owned my 2009 Highlander hybrid since I purchased new from dealer in July 2009. In mid December 2020 I noticed on two separate occasions that with my foot firmly on the brake pedal the vehicle would still be moving a few feet before stopping. No warning lights so I figured no big problem. In January 2021 a warning light flashed on for maybe 5 seconds regarding brake problem. On February 2nd I brought it to my local Toyota dealer to assess. They scanned it and didn't receive any dtc codes. I was advised that my front brake pads were at 4mm and should be replaced soon. I did that. Vehicle drove without incident until June 20th when several warning lights lit up. Abs, tire pressure, brakes and traction. The warning lights stayed on so I brought my Highlander back to my local Toyota dealer. This time I was told that dtc c1391 came up. Abnormal leak in accumulator, replace brake actuator and pump assembly. That would come out to $2901. 24. Toyota had issued a customer support program bulletin regarding the brake actuator and brake booster pump assembly. But for some unknown reason, given the dangerous condition a failure would present, that 100% coverage of replacement expired on December 31, 2020. Toyota is not making any exceptions on this matter. It appears that Toyota is putting their reputation as well as dollars and cents ahead of their customers.
