What owners wrote

“All the warning lights in the day lit up. Brake, LDWS, AEB, outside air temperature won’t read and the a/c blows hot. $486 to diagnose at dealer and they state that it’s an electrical issue due to a bad vacuum pump. I can’t get an answer as to whether the vacuum pump safety campaign was completed or not. Dealer wants $1500 to replace.”

Should you keep driving it?

This page can't tell you that. 1 of 37 reports involved a crash. 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.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
