Should you keep driving it?
This page can't tell you that. 1 of 34 reports involved a crash and 2 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.
