"My 2025 Mazda CX-50 began overheating while still under the factory warranty. During one incident, the engine lost coolant and overheated. I immediately shut the engine off to prevent damage. The vehicle continues to overheat, and the air conditioning only cools properly while the vehicle is moving. When stopped or idling, the A/C stops cooling. I have reported the issue to my Mazda dealer and opened Mazda Customer Experience Case Number 00473077. The problem remains unresolved despite multiple attempts to obtain assistance. I am concerned this condition presents a safety risk." "The vehicle has been inspected by an authorized Mazda dealership on two separate occasions. The dealership kept the vehicle for several days during these inspections but reported that it could not reproduce or identify the cause of the overheating. Despite these inspections, the overheating condition and the air conditioning issue continue. During one of the service visits, I also discovered scratches to the vehicle's exterior that were not present before it was left with the dealership."

The automatic emergency braking in this vehicle is faulty. It misinterprets obstacles and uses the emergency braking inconsistently. I park in a parking garage and I have to slowly (less than 5 MPH) drive up any ramps because it apparently sees the ceiling of the garage as a obstacle and as a result, will randomly brake with no notice (which feels like getting rear ended). The dealer said it is working as designed and said I can turn this function off, but I have to turn it off every time I start the car. I also updated the sensitivity t the lowest setting, which didn’t help. I’m worried about this issue happening when I’m in traffic or bad weather and what might occur, like an accident. I’ve talked with other users of this same vehicle and they have ran into similar issues. Based on my experience, I think the system is defective and is a safety issue.

The vehicle was traveling at highway speeds when it experienced a sudden, violent lateral jerk to the side, causing immediate side-curtain/seat airbag deployment prior to impacting the center divide. I believe there was a sudden, catastrophic mechanical failure of the front suspension componants causing a partial detachment of the front driver's side wheel. This failure mirrors the exact defect described in NHTSA Campaign 24V834000 / Mazda Recall 7925J regarding un-torqued front suspension fasteners. We believe our vehicle suffered from this exact factory build issue despite falling outside the initial recalled VIN list. Insurance claim to follow.

The drivers side inside door handle has quit working twice. The dealer has temporarily fixed it both times, but advised us to "just be more gentle with the handle". The cable is falling off of the door hinge inside the door, and the dealer claims they don't have a way to permanently fix it. They just put it back on its mount. We are afraid that the driver will not be able to escape the vehicle in an emergency. Both instances have been under 10,000 miles. The door handle works perfectly fine until it doesn't work at all. No warning given.
