Common Issues with Toyota Prius Mirrors
The Toyota Prius is one of the best-selling "green" vehicles nowadays and has been in the forefront of hybrid technology since its debut back in 1997. It is one of the cleanest vehicles sold in the United States having one of the best ratings under the EPA. Unfortunately, like all vehicles, it has some drawbacks that users have complained of. Toyota Prius mirrors, most notably the auto dimming rearview mirror, have been noted to have some issues that's been bugging users since launch. Learn how to troubleshoot these problems so you could fix them on your own and get better performance from your Prius.
Faulty auto-dim mirrors
Dimming mirrors are popular vehicle accessories that have been introduced back during the late 1980s. They work by automatically detecting light and then dimming to avoid blinding the driver. Unfortunately for the Prius, this has been an ongoing issue that a lot of users have been complaining about. The most common problem seem to be that the auto-dim mechanism would switch off whenever street lights, building lights, or even car headlights would shine on the Prius. Until the vehicle drives in a spot that's in total darkness, then the auto-dim feature would simply refuse to turn back on. Most users would point out a faulty light sensor, which needs to be fixed or replaced entirely so that the auto-dim would work properly.
Can't turn off the auto-dim mirrors
To further exacerbate the problem with the rear view mirror, some users also report problems with turning the auto-dim feature on and off. A small green led should light up indicating that the auto-dim feature is turned on. If this won't light up, then you might be looking at a connection problem. A quick way to check if it is indeed working is to do a quick test at night. Have someone shine a bright light behind your car and switch the auto-dim feature off. The mirror should turn brighter and whiter after a few seconds, making the view behind your car much brighter and clearer. Do note that it isn't an instantaneous effect, it might take five to ten seconds before this happens. The best solution to this problem would be to have a mechanic check both the sensor and the rearview mirror to see if there are any broken items that would need to be replaced.
