My last trip to Florida in May the driver assist worked flawlessly.

Tomorrow I'm going on a trip to Colorado that will be about 2000 miles total.

The driver assist now ping pongs when engaged. I've come to rely on this on long trips.

I did have my car serviced for 15000 miles last week. Could they have done something? Am I just missing a setting?

Thanks in advance.

 

Check to make sure lane tracing is turned on on the center HMI.

 

You nailed it. Took me about 10 miles to figure it out. Thanks.
