UPDATE: Had my GL almost go down. I would not avoid the recall thinking they are going to cause a problem with your car. From what I can tell there is no perceptible difference and I've only run a half a tank of fuel, but it seems to be getting slightly better milage (I've averaged about 29 MPG over 20K so far since March).

Problem is if you are more than a few miles from a dealer when it takes a dump you will be in trouble and have to have the car towed. Best I can tell is that you have 20-60 miles once the problem starts before your batteries will die.

Took about 2 days for the change out and reprogram on my car.

Just my 2 cents.
