2024 Mazda CX-50 problems

“FORMAL VEHICLE SAFETY COMPLAINT Vehicle: 2024 Mazda CX-50 Subject: Repeated Unintended Emergency Braking, False Collision Warnings, and Persistent Braking-System Malfunction I am submitting a formal safety complaint concerning serious and recurring braking-system malfunctions involving my 2024 Mazda CX-50. The vehicle initially began displaying false collision and braking warnings despite there being no apparent hazard or obstruction. These warnings occurred repeatedly and eventually progressed to incidents in which the vehicle activated its automatic emergency braking system without justification. During one particularly dangerous incident, I was traveling approximately 75 mph on the freeway when the dashboard suddenly displayed a red braking warning and the vehicle automatically applied its brakes with extreme force. There was no apparent vehicle, pedestrian, or obstruction requiring emergency braking. The sudden and unexpected deceleration nearly resulted in a serious collision. These problems are not isolated. The vehicle continues to experience false collision alerts or unintended braking on an almost daily basis, even when no hazard is present.…”

“Front license plate in OEM factory location interferes with forward radar sensor, causing phantom automatic emergency braking events in moving traffic. Vehicle came to complete stop in active traffic lanes on multiple occasions, creating severe collision risk. Removing the plate (in violation of California law) restored normal sensor function.”

“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.”

“Driver of the vehicle was parking the vehicle in a parking lot, foot nowhere near the accelerator when the car suddenly surged forward striking a parking pole.. The driver side front quarter panel took on heavy damage along with the sensors.. Car had to be towed... It accelerated by itself...”

“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.”

“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.”
