Mazda North American Operations (Mazda) is recalling certain 2016 CX-5 vehicles
If the DRL fails, the vehicle's visibility may be reduced to other drivers on the road, increasing the risk of a crash.
Fix: Mazda will notify owners, and dealers will inspect the headlights, and replace the sealing gasket or headlight assemblies, as necessary, free of charge. The recall began March 20, 2020. Owners may contact Mazda customer service at 1-800-222-5500 Option 4. Mazda's number for this recall is 4320A.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering lighting on this vehicle — documented
repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall
(it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

Some customers may experience one or more electrical malfunctions after a vehicle body repair. The newly painted fender stay (2) may be causing a poor front harness (1) ground connection.
Some vehicles may have one of the following DTCs stored in memory along with a system status notice on the Multi-information display OR display a system status notice with no DTC: C1001:92 - Forward sensing camera (FSC) poor field of view [Gen 6 vehicles], B14F0:92 - General temporary failure in forward sensing camera (FSC) [Gen 7 vehicles build on or before March 2, 2019], No DTC - Gen 7 vehicles built after March 2, 2019, DTC C1001:92 or B14F0:92 set as a past record for low visibility of the Forward Sensing Camera (FSC). It does not mean there is an actual FSC defect. In some cases the customer may have a concern with the Lane Departure Warning System (LDWS) and/or High Beam Control syste
Some customers may experience one or more electrical malfunctions after a vehicle body repair. The newly painted fender stay (2) may be causing a poor front harness (1) ground connection.The front fender stay (2) newly painted surface at ground point (3), where attachment bolt (4) is seated, may create a poor front harness ground connection. Customers concern can be resolved by sanding off paint at ground point (3) where attachment bolt (4) is seated. After installing the bolt (4), apply touch-up paint to the exposed base material area of the front fender stay.
Some customers may complain of condensation/fog inside the front (headlamp/headlight) or rear (taillamp/taillight) combination lights. The recent new models have been fitted with a clear lens which can cause the symptom to be more noticeable, however, it does not affect the performance of the light. This condensation/fog is a natural phenomenon that occurs when there is a fairly large temperature difference between the inside and the outside of the light housing. It is normal for very small water drops to appear in certain locations on the light units where the air is stagnant (condensation), making the lens look whitish (fog). This happens mostly in the corners and narrow spaces, and will t

The failure pattern owners describe
Owners report widespread LED daytime running light failures in 2016 CX-5s, typically between 24,000 and 40,000 miles. The DRL dims or flickers intermittently before going dark entirely, often unnoticed by the driver until someone else points it out or the owner sees the reflection in a window. The headlight assemblies are sealed—no individual bulb or component replacement is possible—forcing owners to replace the entire assembly at $887 to $1,600 per side, plus labor.
The 2020 NHTSA recall (20V-063 / Mazda 4320A) was supposed to address this, but execution failed. Dealers reported months-long parts shortages, marked repairs "completed" without performing them, or only installed gaskets that subsequently failed. Mazda customer service sometimes denied coverage despite owners providing VINs and proof of eligibility. Many owners were left out of pocket after warranty expiration.
Owners consistently note this is a design flaw—LED bulbs should outlast the vehicle, not fail in three years. Some report water intrusion inside sealed units; others attribute failure to internal component defects. The lack of any dashboard warning light means owners often drive unaware their daytime running lights are out, creating a safety visibility issue.
Failure modes owners describe
Daytime Running Light (DRL) Flickering and Dimming
LED daytime running lights flicker intermittently or become progressively dimmer before failing completely. Occurs on one or both sides. Owners report the flickering is noticed while driving, sometimes only visible to other drivers or when parked. The problem is not immediately obvious and may go undetected until someone points it out or the light is observed in reflection.
When: Typically between 24,000 and 40,000 miles; most commonly near or shortly after 36,000 miles (warranty expiration). Some failures reported as early as 22,500 miles; others as late as 71,000 miles.
Symptoms owners cite: DRL flickers randomly or intermittently; DRL becomes dimmer than the other side; Flickering progresses to complete failure; No dashboard warning light or indicator; DRL only illuminates when vehicle is in motion
Repairs/costs cited: Entire LED headlight assembly replacement required; sealed units cannot be serviced individually. Repair costs range from $887 to $1,600 per assembly, with labor adding $150–$300. Some owners report quotes of $1,000–$1,500. Mazda has issued revised headlight part numbers (K070-51-031C and K070-51-041C replaced by KA0G-51-031J and KA0G-51-041J), indicating multiple design iterations.
Recalls/TSBs owners mention: NHTSA Recall 20V-063 / Mazda Recall 4320A (issued February 2020) addressed DRL flickering and failure. Repair procedure included gasket or gas-absorption sheet installation on some units and full headlight replacement on others. Many owners report dealers marked repairs as 'completed' without performing them, or only partially repaired by installing gaskets that subsequently failed. Parts availability was severely constrained; many dealers stated parts were on backorder with no ETA for months or over a year. Some owners report the recall campaign was closed or expired, leaving them ineligible for coverage. Two Technical Service Bulletins (TSBs) also issued but not clearly communicated to owners.
Daytime Running Light (DRL) Complete Failure / No Illumination
DRL fails to illuminate at all. Light does not turn on during vehicle operation or when parking lights are engaged. Unlike flickering, this is a total loss of function in one or both DRL units.
When: Between 25,000 and 100,000 miles. Majority of failures in the 30,000–40,000 mile range, shortly after warranty expiration (36,000 miles).
Symptoms owners cite: DRL does not illuminate during daytime or parking light operation; One or both sides affected; No warning indicator on dashboard; Owner discovers failure through external observation (reflection in window, other driver notification, garage inspection)
Repairs/costs cited: Full headlight assembly replacement. Costs $887–$1,600 per unit plus $150–$300 labor. Sealed design prevents individual bulb or component replacement.
Recalls/TSBs owners mention: NHTSA Recall 20V-063 / Mazda Recall 4320A addressed this failure mode. However, recall implementation was inconsistent: some owners report only one side was replaced under recall while the other received a gasket-only repair that later failed. Parts shortages delayed repairs; some dealers could not perform recall work for extended periods (6–12+ months). Mazda customer service sometimes refused coverage, citing VIN mismatch or production-date discrepancies despite owner documentation showing eligibility. Recall campaign closure left vehicles with pending failures outside coverage window.
Headlight Assembly Water Intrusion and Internal Coating Degradation
Water moisture enters sealed LED headlight assemblies, causing internal damage and coating degradation. Coating applied during manufacturing flows or melts inside the sealed unit, creating appearance issues and potentially affecting light output. Sealed design prevents any repair or cleaning.
When: Observed at various mileages; one report noted issue was visible in dealer parking lot at initial inspection. Not time-limited but progressive.
Symptoms owners cite: Internal coating flows or melts inside sealed lens; Clouding or haziness visible inside headlight assembly; Appearance issue worsens over time; Affects light clarity and aesthetic appearance
Repairs/costs cited: Full headlight assembly replacement required. One owner reported dealer acknowledged the issue and promised replacement but avoided contact for six months without resolution.
Recalls/TSBs owners mention: Dealers aware of issue but service delays reported. Mazda customer service directed owners to dealer service centers with no clear timeline for repair. No formal recall issued for this specific defect.
Turn Signal Visibility Obscured by Bright DRL
On vehicles equipped with LED DRL and LED headlights, the bright LED daytime running lights make the dimmer incandescent turn signal bulb difficult to distinguish, creating a visibility/safety issue. Turn signal appears less distinct than the DRL when illuminated.
When: Design-inherent; affects all vehicles with this light combination.
Symptoms owners cite: Turn signal indicator difficult to distinguish from DRL when illuminated; Turn signal appears dim compared to LED DRL; Hard to tell if turn signal is activated when looking directly at vehicle

At 30,000 miles, but out of warranty the driver's day time running light started flickering and at times was completely out. I was told by the dealer that the entire light module needed to be replaced and the part was$1000.00. Daytime running light flickering occurs while driving & when car is parked with motor running.
