Headlight assembly has a singular entity containing the low and high beams, and the daytime running led lights. They are not user replaceable. The drl's fail, requiring a $1200 part and $300 replacement costs for the entire unit. Given these costs, the led lights (which should last 10 years and are failing prematurely between 12 and 24 months) are likely to go unrepaired and negatively impact safety.

2016 Mazda Cx-5 SUV passenger side daytime running light started flickering and became dim at only around 12K miles. My warranty has already expired due to the fact that I bought it in 2015 time frame. The fact that many other Cx-5 owners also have encountered the same problem, at very low mileages, suggest that there is definitely a product defect which is also a safety related problem, given more time down the line.

2016 Mazda CX5 grand touring w/led lighting right daylight running light (dlr) has failed. My 2016 Cx-5 has 25,400 miles and is 3 months out of warranty. These headlight units are sealed, if any light in the unit fails, I am told by Mazda thre is no repair except for a complete headlight unit. If a blub fails the entire headlight unit must be replaced at a $1600 cost. Only a Mazda dealer can replace the headlight unit. Good luck if there is no Mazda dealer nearby. This is unacceptable to me because this is common failure in many other Cx-5's. this is definitely a safety item, driving at night and a entire headlight unit fails, will other units fail? I think so, because this is definitely a design problem with all Mazda headlight units. I would hope that maxda would do the right thing and fix this problem under a recall procedure before someone gets killed. The NHTSA needs to force Mazda to issue a recall on this dangerous defect

The front headlights have been replaced twice on each side and I am waiting on both headlight assembly kits. They tell me it is a $1000 plus cost to me. After speaking with national Mazda (not napleton) I was told they had to make a change. Shouod they not have a recall for this, while waiting for my left headlight my right went out while driving home last night. I now have no headlights for a 30K car. Help

2016 Mazda CX5 grand touring w/led lighting our left led headlight unit daylight running light has failed. We soon learned this a common failure with ours and many other CX5's due to water intrusion. There are units that have failed and units that will fail. Further we learned there is no repair except for a complete headlight unit replacement. The units are "sealed." There is no access even to replace a simple headlight bulb. Should a light fail far from a dealer, at night, one is stuck. We believe this to be a safety defect and that a recall should be issued by the NHTSA to require the manufacturer (Mazda) to replace both defective sealed led headlight units. Our Mazda dealer refuses to deal with this issue on a warranty basis. Based on our research this failure generally occurs around the 36,000 mile mark. If a headlight cannot be replaced, at night, far from a dealer, then a substantial safety issue exists. The daylight running light is a mandated safety item and should always be reliable and functioning. Please note the many other Mazda CX5 owners who have also complained. We first noticed this failure by observing our reflection in a business window. The led daytime lights only come on when the vehicle first starts rolling precluding performing a precheck.

My right headlight was flicker and was covered under warranty. Now my left headlight is out and will cost over $1100 to replace because the warranty ended. Vehicle only as 23,000 miles. There must be a problem with these headlights from all the complaints filed.

- Arcadia, WI, USA

Both front led headlight assemblies seem to be totally unreliable after ~35K to 40K miles and customers are unlikely to quickly replace something that costs $1200 each time. Mazda agreed to fix one but when the second one went bad around 40K (our kid noticed while we were pulling in into the garage at night) they said it's outside warranty and they don't see any issues. There seem to be nearly 20 complaints about this in the last few months just on this one site. The SUV won't pass state inspection without this issue fixed, and at $1200 a pop, drivers are likely to push the limits and drive the SUV without fixing the issue.

- Hillsboro, OR, USA

Driver side led daytime running headlights flickering, and intermittently turning off at 40,400 miles. Pulled over by state police and issued a warning violation for non-functioning headlights. Vehicle will not pass state safety inspection. Appears to be a very common safety issue among 2016 Mazda Cx-5 owners.

- Ossining, NY, USA

The passenger daytime running led light in the headlight assembly either does not work or will flicker during operation of the vehicle. In order for vehicles to pass inspection, all exterior lights must work, so this is a safety issue that Mazda needs to further investigate.

- Rustburg, VA, USA

Right side (passenger side) drl led light strip flickering and/or not illuminating with main headlights either off or on. During daytime driving, with headlights off, led drl not illuminating affects vehicle conspicuousity.

- Edmonds, WA, USA

- Pittsburgh, PA, USA

Failure of led drl (daytime running light) on passenger (right) side. Non replaceable bulb. Requires removal of front bumper cover and replacement of complete headlight module for excess of $1000. Mazda was previously replacing under a silent warranty.

- Pocasset, MA, USA

Led daytime running light on passenger-side headlight flickers and is very dim. On a few occasions, the driver of vehicle in front stated that it looked as if my headlight was out as well. Vehicle is only 3-years old. Mileage should not affect electiral led components. Drl's or headlights are required during adverse weather conditions or when operating the windshield wipers.

- Eaton, OH, USA

Led day time running lights failed on driver's side of vehicle. Known issue with the Cx-5 causing a safety concern since this is not a serviceable part of the vehicle.

- Fort Wayne, IN, USA

The front drivers side daytime running lights on my 2016 Cx-5 have failed after two years and 38900 miles. You cannot replace the "bulb" for a few dollars. You must replace the entire light unit that includes low beam, high beam, turn signal, and daytime running lights (drl). This unit costs minimum of $400 and up to $1200 when installed by dealer. This is an exorbitant price to pay for a simple led bulb that should last longer than two years in the first place.

- Lacey, WA, USA

Daytime running lights do not function while vehicle is in motion or stationary. Problem is reproduced during every trip or by turning on the parking lights when the vehicle is parked. When purchased, I was told I would never have to worry about the new led lights and that they wouldn't burn out like old-style lamps. They have stopped functioning less than 3 months after my 3-year/36,000-mile warranty expired. I have driven less than 22,500 miles and the dealership is quoting me $1,500 to repair what should be <$100 (conservatively) for leds. Looking online, this appears to be a common complaint from owners of this vehicle, and apparently Mazda has revised the replacement part numerous times but people are still experiencing problems and costs to consumers are increasing for this safety feature.

- Jersey City, NJ, USA

Led daytime running lights on headlight now flicker and fail inspection even though no damage or impacts occurred to the headlight. Repair is in excess of $1200. Https://www.carcomplaints.com/Mazda/Cx-5/2016/lights/exterior_lighting.shtml

- South Chesterfield, VA, USA

Led daytime running lights begin to flicker and then fail within just 2-3 years of regular use. The drl lights cannot be easily replaced with a light bulb/replacement led due to the led chips being soldered to the circuit board within the headlight assembly. Full headlight assembly must be replaced. When drl are off it can potentially create safety hazards for drivers of vehicle and other vehicles around.
