“Continuous problem with brakes squealing very loud. Have had brake pads replaced and taken to dealership multiple times to no resolution. It is a huge problem with how loud it is not to mention unsafe and making me feel uneasy about them giving out at any time. This is ongoing from several years ago”

Should you keep driving it?
This page can't tell you that. 2 of 27 reports involved a crash and 1 people were hurt. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
