Interior Rearview Mirror problems of the 2010 Toyota Prius

The autodim rearview mirror does not reduce glare from headlight of cars behind my car. Autodim functionality is not affected by turning the autodim feature on or off (it is the same either ways). The only option I have to prevent glare hitting my eyes is to turn the mirror away so I do not see anything. Toyota customer service says that I should have it checked by the dealership. The dealership shines a flashlight on the rear view and reports that it is working fine. The problem is that the shape of the car's rear glass and spoiler prevents the headlinghts from hitting the sensor on the auto-dim mirror.

2010 Toyota Prius. Consumer states major safety issues with the auto-dim feature of the rear view mirror the dealer replaced the rear view mirror as they determined it was not working properly. After they replaced the rear view mirror, the consumer noticed the auto-dim worked a little better, but it kept turning off. It there were street lights, building lights, or oncoming car headlights, the auto-dim mechanism turned off and would not turn on again, until there was total darkness. The dealership stated that was how the auto-dim feature was intended to work.

The contact owns a 2010 Toyota Prius. The contact stated the rearview mirror was hanging two inches lower than normal rearview mirrors and was obstructing the drivers view of the roadway to the right. The contact spoke with the manufacturer and was told that the rearview mirror design was newer and they were unable to assist. The vehicle was not repaired. The failure and current mileage was 10,000.

I purchased a 2010 Prius level 4. Included in this pakage is an auto dimming rear view mirror with homelink. The auto dimming function does not work properly. It seems to be very distance dependent. There is a narrow focal range that the sensor reacts to. If a vehicle is to close or to far away the auto dimming function does not really dim very much. Considering how low the vehicle is this is incredible annoying and un-safe. Also this vehicle has split rear glass in the hatch back. The center bar I believe also blocks the light from headlights from reaching the sensor. If you tilt the mirror up so that you do not see the center bar (only the top portion of the rear glass), the mirror seems to work better. As a side note, I purchased a manual flip mirror witht the correct part # for a 2010 Prius from my local Toyota dealer and the new mirror has a different mounting style.
