The h3 will not start. Dash screen keeps showing the passlock activated and won't turn off. Computer thinks the h3 is being stolen. I have tried to reset and no luck. I had this problem about 4 weeks ago and changed the fuel pump. Then it happened again last week and now on 28 march 2020. Engine is turning over and electrical systems light up, but sounds like fuel is not getting into the fuel pump again. After doing some research, finding others having the same problem. Recommended procedure is to wait 10 min, still no luck. Waiting 15 min seemed to work before, but now it doesn't. How am I supposed to be safely in the vehicle, drive somewhere and then it stalls again? I am the original owner and haven't had this issue until it started 4 weeks ago. What if this happens while I am driving on the highway and fuel stops going to the pump? This could cause a multi-vehicle accident.

Passlock anti-theft system is malfunctioning causing the dashboard lights and functions to shut down while driving the vehicle which, is very unsafe at night. It also prevents starting the vehicle randomly until you wait 10 minutes, after it resets.

Car has been spontaneously stalling while driving at high speeds. Engine cuts out, power brakes and steering fail, no radio, etc. Vehicle loses all power. It is terrifying. Has happened at least 3 dozen times now. Several visits to dealer could not pinpoint problem. Dealers unable to duplicate stalling, although it has happened to me regularly for months - ie, every time I drive the car (with my two babies) for an extended period on the highway.
