Attention Assist

Just wondering. Has anyone has had attention assist come on and alert them that they were dozing off while driving?

Mine's come on a number of times in 2 years.About 50% of the time they were false alarms and 50% were legit.

Yeah, I've heard from a few people that it had falsely alerted them several times.

I have been falsely alerted twice, both times relatively earlier during my journey. There have been a number of times (4 - 5) that I have been truly drowsy and the Attention Assist never indicated any of them. I've had the ML for 7 months now.

Too Many False Alarms

On several long trips (12-17 hours of total drive time) it seems to go off about 3-4 hours into the trip and then it goes off again every hour or two and not once was my wife or I drowsy! Never seems to go off on shorter drives. Is there a software update to fix this?

2 alerts, both when I was exhausted on a long drive. It works.

I originally posted this because a friend of mine with an C class was drowsy on a long drive and the groove that is cut into the pavement near the shoulder on the highway is what alerted him. The attention assist never went off.

I've only had the 2012 for about 2 months and haven't taken it on any long trips yet so I was wondering what others have experienced.
