Driver assist on other Pacifica years
No other Pacifica model year has enough reports of driver assist for a sheet of its own. See every Pacifica year.
What this problem usually is
These reports come from drivers whose assistance systems did something they didn't ask for. Adaptive cruise switches itself off, or brakes for a car that isn't there. Lane keeping tugs the wheel toward the line, or a "sensor blocked" message appears on a clear day. Because both systems can brake or steer, owners tend to file them as safety complaints, and NHTSA files them under speed control, lane departure or forward collision.
What got replaced
Owners who name the part that was replaced mention the software (4 reports).

Is this a known problem?
The manufacturer has sent NHTSA 1 service bulletin or notice for the 2017 Chrysler Pacifica that deal with this problem. Newest first.
Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.
Cruise Control Inoperative.

No report on this problem is short enough to quote in full.
Should you keep driving it?
This page can't tell you that. 1 of 30 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. How reports land on this sheet.
