My windshield wipers stopped working completely. I am unable to see out my front window properly while its raining. Yes the dealership said that my front body control module needs to be replaced which is the same issue that other Mazdas from the same era have had safety recalls for (nhtsa campaign 19v272000). No it hasn't been inspected by anyone other than a Mazda dealership. The front wipers slowly stopped working. First the highest setting didn't work at all, then the wipers would work sporadically, and now they don't work at all.

I own a 2016 Mazda CX-5 Grand Touring and discovered two brown, burn-like marks on the lower seatback of a heated front seat. I suspect the seat heater overheated and damaged the upholstery. The discoloration is concentrated in the lower back/lumbar area, and I have photographs documenting it. I am concerned that continued use could cause further overheating, burns to an occupant, or a fire. I am reporting this as a seat-heater safety defect and requesting investigation.

Rear subframe corrosion on this vehicle. I am in a winter road salt region, the materials used for this vehicle's subframe are not compatible with consistent driving in this region. Similar vehicles (not mine?) were subject to a recall for the front subframe, but nothing for the rear. This rear subframe issues caused multiple failures of virtually every component of the rear suspension - control arms, rear springs, etc. The repair cost for JUST the subframe was $3813. Not repairing it was not an option - the vehicle had failed mandatory State of Maine inspection (a safety thing, if I'm not mistaken). This should be a Mazda problem, not a me problem. I contacted Mazda USA about this issue…

Repeated Failure and Rebooting of Mazda Connect Infotainment System I am the owner of a 2016 Mazda CX-5. The factory Mazda Connect infotainment system has developed a recurring defect in which the system repeatedly reboots to the Mazda logo while driving. Prior to complete failure, the navigation system became intermittent and Bluetooth connectivity frequently disconnected, requiring repeated attempts to reconnect devices. The system now continuously cycles through the startup screen, making navigation, hands-free phone functions, and system settings inaccessible. These repeated reboots occur while the vehicle is in motion and are distracting to the driver. The flashing and rebooting screen…
