with enough reports we can collectively force GM to recall the SUV or BUY IT BACK... An unexpected engine stall is a qualified "safety issue" according to the NHTSA





this Stall out typically happens from a "Auto Stop resume " this will result in a loss of Propulsion of the SUV, which could potentially result in an accident.. i.e making left or right turn at a red.



this is due to a faulty Aux transmission pump and/or faulty/weak battery or faulty ECM programming ( i suspect battery related)(that does not present a check engine light before hand i.e HV battery code or aux transmission code)



Please make a report with the NHTSA if your SUV has stalled before while driving it..

Please make Sure your SUV engine is running in M4 and the A/C is off Especially if it's an unprotected left turn.. or turning right on a red. this will minimize the potential of a 100% stall out or lag while making a left turn....







this stall out is most likely to happen shortly after the SUV has been cold started i.e after a few blocks of driving...
