LED lamp life expectancy depends on fixture type and usage scenario. LED application to automobile is too new to have any creditable data for reliability concerns one way or the other. For household LED lighting according to the claims from various manufacturers, the life expectancy is 20,000 to 50,000 hours. At 8 hours per day this would be approximately 7~17 years. Supposedly Mazda uses the best quality LED's, this is roughly 30 times longer than incandescent bulbs and 5 times longer than compact fluorescents. So if you replaced your halogen headlight bulbs once for the period of owning the car for 10 years, you may never have a chance to replace your LED headlight unit unless you own it for 300 years! Of course sometimes the environment such as high temperature will cause supporting electronic circuitry, i.e. parts such as capacitors, fails, or even the LED itself fails. But it should be very rare. I'd just enjoy the benefits of the LED lighting and not too worried about its longevity.Just read in owners manual that if LED bulb dies (low/high/drl) the whole headlight unit has to be replaced. So I'm just wondering, what is the expected life of LED lights? Anyone had them replaced?
Yeah, I remember just to upgrade from Bi-Xenon to LED headlights on Porsche Panamera costs $2,900~$3,505 MSRP! (omg)... The best headlights I've ever had are HID's in a Porsche Cayman, maybe not surprising since sports cars are designed to be driven fast. The LED headlights in my '16 CX-5 aren't quite as bright as the Cayman's but they are close. They seem like a great deal, given that they come in a $1500 package that also includes a very competent GPS system and a few other goodies as well.
Who knows? But I bet more people know if the cracked windshield is covered under new car warranty then LED headlights. I even bet nobody will even have a chance to find out!Thanks for that info.
In theory LEDs shouldn't die, but in practice I know that they do, if quality is poor, like in aftermarket LED upgrades (when you replace halogen bulbs with led).
So, Mazda uses the best quality LEDs that are not going to die.
If that's the case, that should be covered by warranty.
Are LEDs covered?
The LEDs and components would certainly be covered under your 3/32 bumper to bumper manufacturer warranty, and likely also by any extended service plan you may have purchased. But, you'd have to investigate the latter to be certain how the contract was arranged.
I need to look into this cracked windshield thing. I thought it was isolated, but that doesn't seem to be the case? I did also see some problems with 14 plus MZ3s as well.
Is Mazda denying coverage/denying issue?

I have the low end headlights with the old fashioned daytime running lights on a 2016 CX-5. Is it possible to replace them with the LED lamps?
You can but high beam illumination will be affected. I'm not sure if non-led '16 is basically the same as '13-'15 non-tech.
Though I've never seen a rating for Mazda's LED headlights, a lot of LED's for automotive use are rated at about 25,000 hours or more. HID's, on the other hand, are usually rated around 2,500 hours. If the ratings for LED's are even close to correct, they should last longer than the vehicle. Accident damage will probably be the usual reason for replacement.

For the CX-5, is there a significant difference in the brightness \ road illumination of the LED headlights versus the standard halogen lights?
I want the legally brightest headlights but the cost of replacing the LED's vs a halogen bulb have me concerned. The LED headlight "system" includes a "power supply" to drop the voltage powering the LED's. This power supply can fail before 25,000 hours, so replacement may be needed for more than an accident damage.
