What got replaced
Owners who name the part that was replaced mention the EPS motor or module (7 reports).

Should you keep driving it?
This page can't tell you that. 2 of 32 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.
