2024 Mazda CX-50 Complaints

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 vehicle had the original OEM battery fail at 15 months. It dropped to 7v under light load. It's a bad battery. Upon being jump started, the power steering went in and out while driving and the dashboard blinked on and off...throwing a lot of errors that are unrelated to the battery problem. The failure state of the vehicle with a bad battery is unlike any vehicle I have ever seen and it is extremely dangerous. Furthermore, Mazda roadside assistance does not know about this issue and only offers jumpstarts, putting customers into danger by suggesting that the vehicle is safe to drive with a battery that is not stable.
