3 Alternator/generator/regulator problem

Failure Date: 05/31/2019

An issue relating to electrical or power train causes the vehicle to stall and remain in a no start condition. Without warning, the vehicle is completely without electrical power while driving and the vehicle becomes unable to be controlled. This vehicle was manufactured 9/2018, purchased 12/18. This incident happened while driving the vehicle on the interstate at a speed of 45-55 mph on 5/31/18 and again while driving at 30-40 mph on a city street on 10/18/19. Both of these incidents were terrifying and thankfully we were not involved in an accident. The only service that has been performed (oil changes and these two issues) was completed by the dealership where it was purchased. Both times the vehicle failed, the dealership discovered that the master fuse was "blown" and the replaced it. This is an unsafe vehicle that I am now forced to pay for and drive myself and my children around in not knowing when it will shut off and I will no longer be able to control the vehicle or move from the flow of traffic. When calling the manufacturer, I was told that the recall number u87 / NHTSA id 18v524000 did not include my VIN number although the description is exactly the same. This recall explains that the dealer should replace the powertrain control module because it may be equipped with a voltage regulator chip in the circuit board that may fail causing a stall or no start condition and potentially causing the vehicle to stall while driving and cause a risk of crash. Yet, the dealership is unwilling to do anything to resolve the issue because the recall does not include this VIN. The manufacturer refuses to acknowledge this issue and this is my only recourse until the issue happens two more times, I survive being in an inoperable moving vehicle and can file for lemon law rights.
