What owners wrote

“During cruise control engagement when passing a larger vehicle the system sometimes will execute aggressive braking potentially causing an accident with a vehicle following behind. Have to be ready to disengage cruise control during all situations with other vehicles in proximity. It will always perform the aggressive braking maneuver when passing a semi-truck on a curved highway.”

“In tighter corners the car coasts/brakes unnecessarily while cruise is on. Seems like a safety feature possibly or a malfunction as I haven't had that on any other cruise controls on other vehicles. Then after the corner it accelerates. I find very annoying. If this is considered a safety feature then ok but it is way to sensitive currently and needs an update.”

“When adaptive cruise control is engaged, and travelling in the left lane of a multilane highway, automatic braking frequently activates when there is a vehicle ahead in the right lane (especially, but not always, a truck) but no hazard in the lane directly ahead.”

“Using the adaptive cruise control in I-64, the car will dangerously slow down/brake in the turns. If someone was following m, this slow down would have been unexpected, and could have rear ended us or lost control trying to avoid us. Unexpected slowdowns are dangerous. Not sure if this happens at lower speeds on side triads since I don’t use the cruise control on those roads.”

Should you keep driving it?

This page can't tell you that. 1 of 31 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.

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