2019 CHRYSLER PACIFICA PLUG-IN HYBRID Steering Problems

While driving the car down a busy 4 lane road at 55mph on [XXX] around [XXX] in Irvine, CA, the car began to shake as the steering locked up and alerts came up on the dash that the power steering had failed. After turning the car off and on it did not fix it. Leaving it off for 15 mins seemed to make the error go away. We had it towed to Tustin Tuttle Chrysler dealership for service. The dealership found the fault code in the log, it was a power steering control failure. They could not replicate the circumstance and insist on releasing the car as safe to drive; putting my family and the public at great risk. The dealership refuse to even run diagnostics on the faulty identified part. They said if they cannot recreate the problem they won’t fix it, even though they see the error code...

Driving along on Aug 2nd and at about 30 mph all electrical systems turned off, acc, blind spot, automatic braking etc, it went into limp mode and I had to pull over. The dealer installed a few updates and reset the codes. I drove it three more days and then it happened all over again this past Sunday the 7th

LANE SENSE BEHAVES ERRATICALLY IN CERTAIN CIRCUMSTANCES; ALERTS LOUDLY AND REQUEST HANDS BE PLACED ON THE STEERING WHEEL WHEN THEY ARE ALREADY ON THE WHEEL AND AM TRAVELING SAFELY WITHIN A LANE; NO LANE CHANGES. HAS ALERTED IN DRIVEWAY AS WELL AND ALERTED FOR SERVICE. TOOK TO DEALER AND THEY COULD NOT REPLICATED OR DETERMINE PROBLEM. THEY PROVIDED INFORMATIONAL FLYER ON LANE SENSE BUT IT DOES NOT MATCH REPORTED CONDITIONS/ALERTS I RECEIVED ON AUTO'S CONSOLE. CONSISTENTLY FAILS AND BEHAVES ERRATICALLY GOING NORTHBOUND ON GOLDEN GATE BRIDGE - IN ALL LANES AND ON MULTIPLE OCCURRENCES. OCCURS IN VARIOUS ENVIRONMENTAL CONDITIONS FROM FOG, CLEAR DAY, RAIN, ETC. OCCURS IN MOTION AND WHEN CAR HAS BEEN STILL/STOPPED (IN DRIVEWAY.) SYSTEM ALERTS AND THEN AUTOMATICALLY DEACTIVATES ITSELF. I DON'T KNOW THAT MANUFACTURER AND DEALERS HAVE FULL UNDERSTANDING OF BEHAVIOR; ESPECIALLY THE DETECTION OF WHAT THE CAR BELIEVES ARE NO HANDS ON THE STEERING WHEEL/FEEDBACK...
