NHTSA Complaint #11483609 — 2017 CHRYSLER PACIFICA

2017 Chrysler Pacifica Touring L First, multiple warning messages started pop up randomly with alarm sound. The speedometer started shaking. The shift gear was unable to change. The engine was unable to start at the parking lot. After dealer mechanic at Envision CDJR West Covina in California inspected, there was no log in obd2 record and they said that it seems communication was failed and returned the car without fixing. A month later, it started again and the engine had completely shut off at the middle of intersection. Called AAA and took the car to the same dealer. They said this time that the electric harness was short and the entire harness needs to be replaced with the latest superseded part which cost $1500. 2 weeks later, the same issue start again. Nothing had been fixed and the car will be towed to the dealer to inspect it tomorrow. I'm risking my life and very scare to drive this car. I really suspicious that this dealer has no ability to detect and fix the real cause of the issue. Please help.
