2016 Toyota Prius: headlights failing or too dim

Filed Apr 11, 2025 · Lights · AZ

The headlights are either too bright or aimed poorly that it blinds oncoming traffic, who frequently flash their high beams at me. This occurs without any load in back and without me using the high beams. Can Toyota either adjust the bulbs or place a film on the headlights to prevent blinding oncoming traffic? Thank you!

Moments ago, I entered my 2016 Toyota Prius to find that my windshield had mysteriously cracked while parked over night. The crack was not present when I last drove the car last night. Based on some online research for windshield replacement cost, I've learned that Toyota was faced with a class action lawsuit regarding 2016-17 Toyota Prius containing defective windshields; in which these windshields are known to unexpectedly crack while parked or under ordinary driving conditions. Furthermore, my Toyota Prius is equipped with safety features (such as pre-collision system, lane departure alert with steering assist, automatic high beams and full-speed dynamic radar cruise control) that require a front camera to function properly. The cracked windshield now interferes with the camera's visibility, line of sight and perceived orientation, thus causing me to feel unsafe while driving the vehicle. I am filing this compliant because I am now faced with not only an unsafe vehicle to operate, but also the cost to fix a windshield that is known to be defective from Toyota.

Condensation building up in passenger side headlight. The car has only 31,200 miles. Not cracks visible from outside on headlight assembly. Condensation distorts the light beam and dimming the light intensity.

When driving with a heavy load in the back or with large adults in the back seat it causes the headlights to point upward blinding on coming cars. Yes you can manually lower the lights via the screw under the hood but that's an inconvenience as I will not be able to see further down the road. Sometimes the headlight blinds oncoming cars even without a heavy load causing oncoming cars to flash me and I have to flash them back to prove to them I have my lows on. At times when I get too many flashes I end up driving with just the dim day running lights to make sure I don't blind oncoming cars causing me to compromise my night driving safety. Toyota should provide auto leveling headlights lights or a firmer suspension to ensure the level of the head light is pointing where it should be.

While driving at night, rear view interior mirror does not dim as traffic approaches from rear. When taken to dealer, technician shined light from iphone onto mirror and it dimmed properly. However, under normal driving conditions it does not! On a recent 2 hour nighttime drive, as car lights approached from behind, I alternately turned the dimming feature on and then off and noticed absolutely no difference. I even tried it when stopped at red light with headlights from several cars behind me, with the same result. Since there is no lever to use to dim the traffic as there might be with a non-electronic mirror, I was forced to lower the mirror to avoid being blinded by cars approaching from rear - an obvious safety situation. Dealer says there's no problem but has not tried in real life driving.
