2022 Mazda CX-5

Humming sound coming from driver’s side headlight as soon as unlock bottom pressed in key fob. This sound comes from a faulty cooling fan inside the headlight and is a known defect. Humming sound progressed to very slow pitch indicating that fan function is diminishing over time. Mazda will replace the headlight but required me to pay $200 toward it. This should be a recall with replacement at no cost to the consumer as they are aware of the defect.

The mechanical motor assembly inside the adaptive front-lighting headlamp unit has failed on my 2022 Mazda CX-5. This mechanical malfunction severely compromises nighttime driving illumination, creating a direct road hazard by reducing forward visibility during essential evening commutes. An initial repair and parts request was submitted to Mazda several months ago, but no corporate response or resolution was ever received. The vehicle and component are currently available for inspection at Yark Mazda in Toledo, OH, where technicians have confirmed the headlight motor failure. Because the prior request went unanswered, the dealership has advised me to contact Mazda corporate directly to follow up. No dashboard warning lights appeared prior to the component failure.

My 2022 Mazda CX-5 Signature began producing a loud whirring/rattling noise from the driver-side front headlight assembly. After investigation, the noise was identified as coming from the internal cooling fan located inside the LED headlight unit. The cooling fan, which is integrated into the bi-LED headlamp assembly, appears to be failing prematurely due to bearing wear. This is a known widespread defect on 2019–2023 Mazda CX-5 models. Mazda has already issued Technical Service Bulletin (TSB) 09-015-23, which acknowledges the noise issue and instructs dealers to replace the entire front combination light assembly under warranty. However, no formal recall has been issued. The root cause appears to be Mazda’s design decision to use the full LED headlight beam as the Daytime Running Light (DRL), which keeps the headlight cooling fans running continuously whenever the vehicle is in operation — even in daylight. This accelerates fan bearing wear far beyond normal expectations. The headlight assembly costs $1,200–$1,700 per side to replace out of warranty. Owners whose warranty has expired are facing repair bills of $2,400–$3,400 for both sides. This constitutes a significant safety risk as headlight failure reduces nighttime visibility. I have scheduled a warranty repair at an authorized Mazda dealer under TSB 09-015-23.

The contact owns a 2022 Mazda CX-5. The contact stated that while driving at nighttime at undisclosed speeds, there was an abnormal sound coming from the headlights. No warning lights were illuminated. The vehicle was taken to a local dealer, where it was diagnosed with an unknown headlight fan bearing failure. The vehicle was not repaired because the warranty had expired. The manufacturer was not made aware of the failure. The failure mileage was approximately 37,000.

Mileage

37,000 mi

Both LED headlights died within two months of each other on this relatively new vehicle. Outside the three year warranty, but only 27,000 miles (well within the 36,000 warranty period). As it's outside of the three years, the warranty already expired regardless of mileage. One headlight was grinding (fan) while the other's low beam simply died. Each headlight cost $2800 to replace. You can't simply replace a burned out bulb with this headlight design. The entire unit must be replaced at a cost of almost $3000 depending on your dealer. This is a major safety issue when headlights die while driving at night. This is not a user maintenance issue. It is not normal wear and tear. Almost $6000 dollars to replace poorly designed headlights within two months of each other on a new-ish vehicle while being a safety concern constitutes reason enough to issue a recall, and to reimburse owners for previous replacements.

RH LED headlight cooling fan failure. Diagnosed by Mazda dealer and quoted $2450 cost. Vehicle is just outside warranty coverage by 2900 miles. This is a very well known and documented problem that Mazda is not standing behind. Owners are removing the relay for their daytime running lights, rendering them inoperable in order to save wear and tear on the headlight cooling fans. This is a safety hazard.

SA-061/25 12/17/25 DESCRIPTION If you encounter any type of electrical concern (e.g, dead battery, engine no start, DTC(s) stored...), interview the customer before proceeding with normal MGSS diagnosis by asking if any aftermarket devices have been installed. Aftermarket devices may be the cause of the electrical concern. Below are a few examples of unusual electrical concerns caused by aftermarket devices. Examples: 1. Devices connected to the DLC-2 (battery discharge/DTC stored) 2. Devices plugged into the 12V outlet 3. GPS tracking device (engine no start/battery discharge) 4. Dash cam (DTC stored) 5. Non-certified USB cable (Apple Carplay™/ Android Auto™ will not connect) 6. Over-sized wheels/tires (incorrect GPS location) 7. DTC C0023:14 8. Decorative trim and/or cover on the START/STOP ENGINE button Example 1: Some electrical devices connected to the DLC-2 connector by insurance or mobile phone companies may cause: Battery discharge. The device may disrupt the CAN system battery saver mode. • IDS/MMDS will not communicate with the vehicle due to poor DLC-2 connection. The aftermarket device may cause DLC-2 female terminals to spread open.
