why can I only see through half the windshield when headlights are on at night

For a 2014, I would take it back to the dealer. Possible headlight misalignment?

I have the same issue with my 2015 Corolla. The top part of the windshield seems is darker, then lowers down the windshield while driving. It's very distracting.

My father is having the same problem. Please report it to https://www- odi.nhtsa.dot.gov/ivoq/. My father believes it's due to the high intensity lights and strip they put on the light itself. When he goes down hill at night the windshield goes dark and is very scary to drive. Several others are having same issues but it's not being reported enough. He has a Toyota Corolla S 2015. Dealer was no help.

I am having an identical problem with my new 2016 Ford edge. Very Scarry. Took it back twice and the dealership and they adjusted the headlights each time, but this has not corrected the shadow problem. I do intend to complain direct to Ford since the dealership has no answers. Anyone else out there with a Ford edge that you are very weary to drive at night?

Our new Kia does the same thing, my sister in laws Toyota is worse. It is the high position of the lights, not the windshield itself.

I live in the forest near Yosemite and recently and to my GREAT regret bought a 2017 Rav4 and discovered the Windshield of Death. Yes, it's because of a sensor in the windshield and the dealer KNOWS IT because the dealer I bought mine from replaced the windshield with a normal one for $285 (I'm trying to collect from Toyota headquarters.) NO ONE I talked to knew anything about it, the salesmen are idiots and the service people don't want to bother about it. You can get a mobile glass guy (NOT Safelight, they were jerks), that's who ended up doing mine. Save your life and get rid of this "Safety feature." ALSO on the windshield is the thing that tells you when you're going out of your lane, so I guess it's a car for drunks? That will go when you replace the windshield, and good riddance. Don't let anyone tell you that you can't replace the windshield. Save yourself!

Don't get another windshield, it's not the windshield. I found out the hard way. There are codes that the dealership can put into the computer that runs the Safety Sense features. Don't listen to jerks who tell you it can't be fixed, they're incompetent and dishonest if they do. Worst car experience in 53 years of driving. Piercey Toyota in Milpitas CA is the worst dealership with incompetent uncaring staff. Buy a Honda.

Don't expect any help from the dealerships or the Toyota regional customer service people. They're there to give you the runaround until you just give up and live with any abomination they stick you with. I curse the day I bought my Rav4 and can't wait to sell it.
