Consumer Description

I have been experiencing intermittent brake issues with this car now for the last 50k miles. Sometimes the warning lights on the dash will activate, sometimes not when I am experiencing issues. the power assist is the problem. - it activates and then deactivates without warning instantaneously, while applying brakes or not. Sometimes when I am applying the brakes without the brake assist working, it will instantaneously start working without warning, causing my car to almost lock up its brakes. This is very dangerous, especially in traffic. When I apply my brakes at any given time, I never know if I am going to have power assist or not. I have replaced the brake master cylinder once already with a mobile mechanic and the problem went away for about one year but now it is happening again so this seems to be a reoccurring issue with this car. I have decided to just stop driving the car and bought a different one. I am a delivery courier and I cannot be driving a vehicle unsafe as this. I have reported the issue to my local dealership, but they are refusing to troubleshoot without charging me and it’s telling me there are no recalls.
