Engine Stall Problems of BMW Z4

Engine unexpectedly stalled and shutdown while in movement with potential to cause accident. Vehicle cannot be turned on until full stop is achieved and transmission placed in "p. " idle engine rpm continues to vary drastically up and down with indication a problem persists and is likely pose the same safety risk. I bought vehicle used on 2012 and had the issue shortly after purchase twice at highway speeds. Dealership took months to apparently resolve. I am back at risk.

The car has stalled multiple time when coming to a stop. In some instances I did not have to come to a complete stop such as crossing a divided highway, just slowed significantly. As I went to accelerate through the intersection the engine had stalled and I was stuck in the middle of the intersection with no power. Car starts right back up each time but you must stop to place the car in drive(automatic transmission). Nearly hit by oncoming traffic on 3 separate occasions. Dealership was able to replicate, sold me a $400 battery as the fix. Car stalled on the way home from dealership. Returned the car but they could not replicate and since the instances did not produce a fault code they could do nothing. Car continues to stall which makes it a safety hazard. There are 100's of post on BMW forums with the same issue but BMW claims to have no knowledge of the issue. Someone needs to step in and make them address the issue. This is not the known battery cable issue, that was replaced per recall.

I am leasing a 2009 Z4 BMW, the engine car stall while driving this happened twice in a period of 2 weeks, I almost have a car crash behind in both opportunities, thanks that the traffic was very slow, the second time I have to go out the road. I brought the car the for service, they were able to reproduce the failure, after one week at the shop they say it was a computer failure, they replace the computer however after 2 weeks the car still in the shop I have call several times to customer service and the service shop but I don't get any specific answer of what is going on, I feel I don't have any rights as a consumer and in the other hand I am concerned for my safety since they said they don't guarantee this won't haven again even if the car is fixed. Do I have any rights as a consumer or I have to accept this situation.

: the contact stated while driving 55 mph on the highway, the engine stalled without warning and there was a loss of all vehicle power. After an extended period of time, the engine restarted. The vehicle was inspected by a dealer numerous times, but was unable to duplicate the problem. The manufacturer was alerted.
