Initial incident happened while driving on a street. Door locks power cycled lock/unlock and then the car would cut off. No warning, no time to move to out of traffic or turn on hazzard. I use this vehicle to commute to and from work/childcare etc. I also travel of the freeway alot. That was the previous incident. The most recent incident occurred when the car would not turn over and upon doing research we found that it may be related to. Relay issue due to the fuze box being underneath the rear seat. GM claims that because a bracket used to fasten the seat in place interferes with the fuze box and presses down on the fuze pump relay and causes it to burn out. After switching out the relays with the suggested lower profile relay, the car drove for a few hours and then when we parked we couldn't remove the key from the ignition. Upon lifting the back seat to disconnect the battery we smelled and heard the fuel pump relay burning and sizzling. Since the car was "serviced" by a Buick dealer in June I'm assuming that it wasn't actually serviced the relay was just replaced and maybe a few other tweaks here and there but the issue was not resolved. I am very concerned about the reliability of this car. I have children that ride in the back seat. I am fearful that the car will catch fire or spark.
