What is the reason for the CX5's rearview mirror not folding properly?

cx5 rearview mirror does not fold properly due to a malfunction in the rearview mirror folding unit, which is a common issue with the CX5. During the vehicle's warranty period, you can claim a free replacement from the 4S store. The function of the rearview mirror folding feature: As the widest component installed on a car, the rearview mirror is most susceptible to impact in case of friction. To minimize wear and tear, the rearview mirror needs to have a folding function. Rearview mirrors with a folding function can be retracted when passing through narrow roads, improving the vehicle's passing ability. It can reduce parking space and effectively avoid scratches. Location of the rearview mirror folding button: In most cases, the rearview mirror folding button is located in the electric opening and closing area of the driver's side door, but there are exceptions, such as the gear shift base area.
My Mazda CX-5's right side mirror has recently been getting stuck halfway when folding. Upon closer inspection, I noticed a lot of dust and mud accumulated at the pivot point, probably from splashing in during a rainy off-road drive last time. After cleaning it with a toothbrush and spraying some WD-40 lubricant, the folding action is much smoother now. This kind of mechanical jamming is particularly common, especially in northern winters when ice buildup makes it worse. I recommend using a water gun to rinse the mirror pivot gaps during car washes and applying anti-rust lubricant every six months for maintenance—it can save a lot of trouble. If not addressed promptly, the motor may burn out from prolonged overload, and replacing it could cost several hundred dollars.
There are usually several possible reasons for the side mirror not folding properly: First, the motor gear may be worn out, causing inaccurate transmission due to long-term repeated folding. Second, the limit sensor may be faulty, preventing the system from detecting the fully folded position signal. Third, there could be poor wiring contact—I've seen cases where water got into the connector. Fourth, it could be a program glitch, which can often be resolved by restarting the ECU after disconnecting the power. Owners with strong DIY skills can remove the housing to check the gear condition. If the gear is missing teeth, the entire assembly will need to be replaced. However, the CX-5's mirror housing clips are particularly brittle, so be careful not to break them during disassembly—it's best to let a professional technician handle it. Aftermarket replacement parts cost around 500, while OEM parts are more expensive.
