Toyota Corolla headlights problems

WINDSHIELD-VISIBILITY: Description of Safety Defect & Incident: I am reporting a severe, life-threatening factory manufacturing defect internal to the windshield glass of my 2026 Toyota Corolla w approximately 1200 miles. I noticed this defect shortly after taking possession of the car, although the daytime sun was higher and I though that windshields might be made differently. It was a confusing situation. Under specific lighting conditions, the defect caused catastrophic light scattering, resulting in an instantaneous and complete loss of forward driving visibility. On 9/22/26, while driving up a hill at approximately 6:30 PM (sun low during sunset), the vehicle reached the crest of the hill where the sun struck the windshield directly. The defect caused the entire windshield to instantaneously "white out," blasting intensely scattered light across my entire field of vision. I was completely unable to see the road, AND there was oncoming traffic, I couldn't see the lane markings either. I immediately and blindly pulled to the shoulder, and after a few minutes (to adjust my eyes back to normal) I inched forward until the angle of the sun shifted and I was able to see again. During nighttime driving, the defect distorts light from oncoming vehicles - headlights are bent and stretched into blinding, very large "cross" shapes and starburst halos that blur my vision and make nighttime driving also dangerous. I attempted to clean the glass and even tried a little scrape with no effect. Where and at what angle the daylight shines on the windshield determines the severity of the effect. Oncoming lights at night are worse with bright LED's. I request that the federal safety agency investigate before this defect causes a fatal collision. The car was delivered to the dealership first thing the following morning on 9/23/26 and the dealership shop manager witnessed the defect in the morning light. I offered to take a drive but the shop manager declined. The car is available for inspection.

There is a shadow or "dark spot" observed in the LED low headlight beam. It is distracting while driving. The dark spot is distracting, sometimes you think an animal is coming into view, causing confusion. It is especially noticeable on totally dark roads in remote places.

This Complaint is not about a specific incident, but about excessively-brilliant (blinding) headlights. In the flow of traffic, the blinded drivers far outnumber the vehicle using blinding headlights. The area those headlights cover spreads out so WIDE, the blinded driver is not able to see the side of the road. Insurance companies may say this problem does not cause accidents; but, I believe that is because many drivers do not dare risk driving at night. Excessively-brilliant, blinding, headlights should be BANNED and Recalled. Those headlights are a terrible safety concern and should have been banned years ago.

I was driving west bound on I40 with the adaptive cruise control, and lane assist on at 75 MPH. It was around 8:30 PM when I seen the instrument panel flash, just drop for less than half a second, and then come back up but dimmer, like when the headlights come on, except they already were on. At that point all engine noises stopped and the car felt like it was actively braking. I literally lurched forward in my seat. I noticed that the RPM's had dropped to zero and I didn't see anything on the dash that indicated any warning. All green icons and nothing red. Stepped on the gas pedal, nothing. Tried hitting the cancel on the adaptive controls, nothing. I started turning the car from the inside lane to get to the outside shoulder while shifting the car into neutral to get more drift and tried toggling the key from off to start position and the engine. No rev, no RPM's. Car stalls in the outside lane. I turned on the flashers and then put the vehicle in park, removed the key and then re-entered the key and tried to start. Nothing. Attempted to push the car out of the lane in neutral but I wasn't able to get it to move. A couple semi's go by and I about pooped my pants. Waited for highway patrol to come by and get the car towed. Very fortunate no one was hurt or killed. I believe the automatic emergency braking activated or the electronic parking brake activated? All of the interior systems still had power.

After the car is warmed up after driving for a few minutes, I stop at a red light and the car's RPMS dip from 700 rpm idle to 500ish rpm, when it starts shaking. Then the RPM would go back up to 700 rpm. This only ever happens when in Drive and foot is on the brake. If I shift to neutral or park it goes away and idles normally at 700 or higher RPM. A/C on or off has no effect on this. Oddly enough, if I turn on the DRLs or full headlights, the RPMs don't dip. I feel like it will only be a matter of time before the RPM will dip low enough to the point where the engine will die on me. This is a safety concern. No check engine lights. I have cleaned the MAF sensor, changed engine air filter, cleaned throttle body, changed PCV valve, cleaned injectors, run fuel injector cleaner through the gas tank, replaced my engine mounts. Still, the issue persists. I have no idea why.

I have a 2019 Toyota Corolla hatchback and the headlight went out. Instead of replacing the bulb Toyota has made it so you had to purchase the entire unit which is called a headlight assembly unit and that’s in the thousands of dollars the LED lights are supposed to last the lifetime of the car so it makes it really unsafe to drive at night Currently my passenger side light has gone out and like I said it’s in the thousands to replace it so I’m unfortunately not in a position where I can do that and now my driver side light is starting to flicker and starting to cut out. There’s no way to just replace a bulb you have to replace the entire unit which is in the thousands of dollars it makes it very unsafe to drive at night. And Toyota has stated that the LED lights should last the entire life of the vehicle if not longer.

Exterior headlight design is a big safety issue when driving at night. The low beams do not offer enough lighting when going around turns or hills. Even on flat roads it is not enough and very dangerous. The high beams help but are also not providing the visibility needed at night . When raining and using low beams at night it’s like driving in the dark! Please redesign!
