You can remove the rearview mirror and apply some hot glue inside to solve the drooping issue. Here is some relevant information: Applicable scenarios: Rearview mirror dash cams are not suitable for all vehicles: For rearview mirror dash cams, many brands and models will have labels indicating compatibility. The size of rearview mirrors is not fixed; some imported vehicles have thicker rearview mirrors, and the clips of the rearview mirror dash cam may not be able to secure them completely. Additionally, some vehicles' original rearview mirrors are longer than the rearview mirror dash cams, which can create blind spots in the driver's field of vision.

I've repaired quite a few cars, and the issue of the interior rearview mirror sagging is quite common. The reasons are mostly due to loose bracket screws or aging of the internal damping pad. The solution is simple: first, locate the connecting screws on the mirror arm and tighten them with a small wrench or hex key; if it's still loose, take it apart to see if the damping pad needs to be replaced or if some threadlocker should be applied. Be careful not to use too much force during the operation to avoid damaging the plastic parts. If you can't handle it yourself, just take it to a repair shop—it'll be done in about ten minutes. Since daily driving involves a lot of vibrations, it's recommended to check the bracket every six months to extend the lifespan of the parts. Additionally, in high-temperature areas, the mirror is prone to deformation after parking, so try to avoid direct sunlight and consider adding a small protective cover to help prevent aging.

Once while driving, I noticed the rearview mirror was drooping and shaking badly, so I fixed it myself: tightening the screws on the mirror base with a screwdriver stabilized it; when tools weren't available, temporarily using double-sided tape as a cushion also worked, though not as well as a permanent solution. Afterwards, I often remind myself not to twist the mirror carelessly, and when washing the car, I check if the bracket is loose—this habit saves a lot of trouble. Drooping is mainly due to screws not being tightened properly or the cushion wearing out over time. Regular maintenance includes cleaning dust to prevent buildup that accelerates loosening.

A drooping interior rearview mirror directly impacts driving safety by causing visual deviation, making it difficult to see the traffic behind and increasing the risk of rear-end collisions. If this occurs, immediate action is required: either attempt to tighten the screws yourself or seek professional repair—do not delay. Additionally, develop the habit of checking the stability of the rearview mirror before starting the vehicle to ensure there are no signs of looseness in the mirror arm. In the long term, opting for original equipment manufacturer (OEM) parts ensures greater durability and prevents frequent drooping.
