I had left LED DRL go out on my '16 EX CVT Coupe last fall. It was replaced under the extended warranty without any hassles. Took ~2 days after dealer placed the order before it came. I only had to wait ~1 hr after the service paperwork was done to get the car back on the road. The new one is brighter than the old one on right (probably not surprising), but it's also a bit more blue than the old one too.
The '17 HAH Touring probably has different headlights because -IIRC- those headlights are also LED, while on my EX, only the DRLs are LED. So these part numbers may not mean much for you, but only the "-A#" changed:
Left original: 33150-T3L-A61
Replacement: 33150-T3L-A62
Before you go in for service, look around on line to find what the latest "-A#" is for your Touring headlights, and ask the dealer if that's what they'll order/install.
So far, my right one looks OK. Sorta hoping it dies in next 2 years before the extended warranty runs out on my '16.
If by "lane line avoider died", do you mean LKAS (Lane Keeping Assist System)? Did you get a error message? Are you sure you didn't accidentally switch from ACC (Adaptive Cruise Control) to "standard" cruise control by pressing the button on the steering wheel? If you disabled ACC, LKAS will also be disabled...
