Brake Disc Caliper problems of the 2006 Toyota Highlander

The brake accumulator/actuator is a defective part and Toyota has refused to honor the repair. They manipulated owners by having a warrenty support program with end dates, instead of having a recall on it. Which is why when I researched before I bought, is not listed on car fax. The warranty support was before I purchased vehicle and previously it was either ignored or missed between owners. They have had many of these and get away with it. Right now there is a class action filed in ohio over this same issue with other cars. It is a $3000 dollar part and not a knob on radio. It is a safety issue due to it being part of the braking system. I've seen where the support program said miles didn't matter but when talking to Toyota they say 114,000 miles. The car is a 2006, yeah that's reasonable, even for 2017/18 letter. While driving the vsc alarm system comes on and the braking becomes difficult. The pump has always made a sound but was told by dealer it was the security alarm system making the noise. It happened in 2019 also, the alarm, but repair shop said it was calipers, so paid $800 to have them replaced with pads. Its always made noise but the alarm system started back up again last month. Now with research on my own, I know exactly what it is but Toyota said they sent letter to previous owner and sorry about my luck! this has rendered this vehicle worth $5500, worthless. Cant trade in a vehicle like this and lost my income from delivery with it. I have checked off everything that would apply if it was a recall but since the support program has an end date to get out of Toyota ever being responsible for their defective part, they push it off on owners. I'm just lucky, I have a cdl and good driver and have not had an accident with it. I filed a complaint with Toyota and they just swiped me away as another poor sucker that didn't figure it out before I purchased.
