That one thread has 9 failed LED DRL examples only from 2016(.5) CX-5 GT with Tech Package. There's another thread has several but I can't locate it right now. I actually don't see too many failures on those accent strip DRLs in person on the road, that's why I'm concerned about LED quality of our CX-5.
And why you see more issues on LED DRLs? Becausd they're on all the time and they should fail early. I can predict the LED headlights on 2017 CX-5 will have more failures than 2016(.5) CX-5 as the headlights are on all the time. And we can live with failed LED DRLs, but can't live with failed LED headlights.
