“About 15 miles into my drive to work in my 2015 Lexus rx 450h with only 6,300 miles, my dash panel indicated the following errors: check ABS, check bsm system, check headlight leveling system, brake malfunction, check hybrid system, check power steering system, speedometer at 0 MPH and every possible error light possible. As I attempted to slow down from 65 MPH on the interstate 5, I noticed I was experiencing complete brake failure and were not functioning properly. With aggressive force, I was able to engage the brakes but noticed an extremely loud metal on metal sound when doing so. …”
