2024 MAZDA CX-5 Complaints

Passenger side headlight was making a loud noise. When it began, it happened sporadically, but in ~two weeks, it happened consistently whenever the car was on and could often be heard while driving. The sound was consistent with other reports of the headlight assembly failure and those covered by TSBs for 2019–2023 models. The vehicle was brought to the dealership, the noise was verified as being the headlight failure, and it was replaced under warranty.

I was attempting to mount my bike rack. To get the clips to properly fit I needed to partially open the liftgate. Upon triggering the door release the power liftgate and began opening the door. The anti pinch system did not detect the pinch and it crumpled the roof and liftgate at the seam. I tried to stop it but there was too much pressure and by the time it stopped lifting under my body weight significant damage had occurred. If a finger had been there it would have been chopped off.

While driving on the freeway, the car stopped having the ability to accelerate. The engine light came on, and I received a notification on the Mazda app stating there was an "engine malfunction." I took it to Mazda, and they told me nothing was wrong. Flash forward a month and the same exact situation occurred. I took it to Mazda, and they told me the same thing. This is incredibly dangerous, as losing the ability to accelerate on a very busy freeway is life-threatening.

The contact leased a 2024 Mazda CX-5. The contact stated that the yellow electronic emergency brake light was displayed. The cruise control and rear brakes were inoperable. The brake pedal was pulsating while depressed. There was smoke coming from the front brakes. The vehicle was taken to a local dealer, who replaced the brakes, and the module was inoperable, but the failure recurred. The vehicle was taken to three independent mechanics, who determined that the rear brakes were firm. The manufacturer was contacted, and a case was opened. The failure mileage was approximately 24,000.

Vehicle was dormant overnight and caught fire. Battery disintegrated and fire tore across the entire engine compartment and front end. Fire department conducted investigation and determined mechanical failure. Showed no signs of issue before hand was driven shortly the night before to move parking spots.

Incident Description: On multiple occasions in January and February 2026, while operating a 2024 Mazda CX-5 in reverse on low-friction surfaces (snow/ice) with a slight incline, the vehicle suffered a total systemic failure. System Failures: While reversing at low speeds, the engine spontaneously shut off without warning. This resulted in an immediate loss of power braking and power steering. Simultaneously, the electronic gear selector (shifter) became non-functional, preventing the vehicle from being placed into 'Park' to stop the uncontrolled rearward slide. Safety Risk: The vehicle became a "runaway" object on several occasions. In one instance, the vehicle narrowly avoided crushing a pedestrian against another parked car, stopping only when the tires reached a different surface texture. In a separate incident, the vehicle slid uncontrolled down a residential hill, striking snowbanks. There is a grave concern regarding whether the Supplemental Restraint System (airbags) remains functional during these engine-stall events, as the dealer could not confirm occupant protection status during a total power loss. Inspection & Reproduction: The vehicle was presented to an authorized Mazda dealer on March 3, 2026. The service department attempted to replicate the issue by reversing over soapy water on a gravel surface. However, due to the high friction of the gravel, they were unable to induce the specific tire-slip/low-traction conditions required to trigger the malfunction. No error codes were found during an informal scan, and no warning lamps or messages appeared prior to or during the failures. Component for Inspection: The vehicle is available for inspection. I believe the failure is rooted in the traction control or engine management software, which appears to improperly shut down the powertrain when it detects specific wheel-spin patterns in reverse, subsequently disabling critical safety systems including brakes and transmission locks.

On 02/27/2026, a 2024 Mazda CX-50 (20700 miles) exhibited a severe burning smell following a 3-hour highway drive and a subsequent steep, 2-mile mountain climb to a restaurant in Jasper, TN. The smell was strongly observed by multiple occupants upon exiting the vehicle. On 03/02/2026, a technician at Mazda of Knoxville confirmed via video a 'flat grease ring' slung onto the undercarriage, indicative of a centrifugal lubricant leak from the driveshaft/CV assembly. The proximity of this flammable grease to the hot exhaust system during high-torque operation (mountain climbing) presents a critical fire hazard. Despite visual confirmation of the slinging grease, the dealership issued a blank service invoice, omitting the defect from the official record and returning the vehicle in an unsafe condition. This represents a documented safety defect being suppressed by the manufacturer, posing an unreasonable risk of vehicle fire or catastrophic driveline failure.

The contact owned a 2024 Mazda CX-50. The contact stated that while driving at an undisclosed speed, after exiting the freeway, the contact was distracted, and when the contact turned to face the road, the vehicle rear-ended the vehicle in front. The contact stated that from the impact, the vehicle that was rear-ended was pushed into the vehicle in front. The contact stated that the crash imminent braking and the forward collision warning failed to function as intended. The contact stated that the driver-side air bag and the knee air bag were deployed. The contact was unsure whether there was a warning light illuminated. A police report was filed. EMS was called to the scene. However, the contact refused to go to the hospital by ambulance. Afterwards, the contact went to the hospital. The doctor diagnosed that the contact had a swollen spleen on the left side. The contact stated that the shoulders and back were sore, and the left knee was swollen. The contact attended physical therapy. The contact was able to drive the vehicle back to the residence. The insurance company towed the vehicle to an unknown location and deemed the vehicle a total loss. The manufacturer was notified of the failure, and a case was opened where assistance was declined. The failure mileage was 16,937.

Premature failure of headlight assembly unit, (buzzing sound, known issue) completely unacceptable for this to happen right out of warranty. I don't think I will touch another Mazda in the future.

My headlights have a motor (or motors) in them. This feature is to adjust headlights in accordance with the steering wheel. I think it's referred to as AFS (Adaptive Front-lighting System). The left headlight's motor makes a noise. I do not always hear it when driving but when stopped or parking and exiting the vehicle, I can hear it until the lights turn off. The car has about 37,000 - 38,000 miles on it.
