2017 Toyota RAV4 lights problems

Rear tailights are subject to water infiltration, which has worsened over time. Inside of the lights will fog because they are retaining moisture. This could eventually lead to the brake lights not coming on.

The tail light assembly on these vehicles seems to be a reoccurring issue reported by other owners on online forums and unfortunately we seem to fall under the same category. Water and moisture constantly gets into the rear brake/turn lighting assembly and has been constantly burning out the bulbs it’s become quite ridiculously expensive now. How was my safety put at risk? Well it’s the brake lights! If my brake lights are out or greatly dimmed from moisture that puts me at a higher risk of having someone rear end me at any moment! No the component has not been inspected again by the dealer! I had already brought it up once during a regular maintenance visit but was ignored. There was no warning lamps or such thing. I can not remember when it first began to give problems. But the most recent incident where I had to change out all the bulbs again was just recently on 09/02/2026

While we were driving in the mountains, the wiring harness shorted and fried all 4 of our front bulbs, causing us to have no visibility while driving on unlit back roads in Colorado. Toyota has a known TSB for this issue but claims it's not a safety issue, and has a kit to repair the issue, charging us $500 to install the kit. When asking about this 2 different employees explained it was a design issue with the car. Why is this not a recall? How is frying all my headlights not a safety issue?

Even when properly aimed, with new headlight bulbs, visibility is poor at night. I recently had an incident while driving in town at less than 25 miles hour where I almost hit a deer that I could see on the side of the street, and this is actually not the first of many such incidents. I feel unsafe driving the vehicle at night due to the poor amount of light put out by the headlights. Toyota should offer to retrofit these with LEDS for people with issues. It's downrigtht scary, especially on poor lit streets or driving on the highway.

Both of my headlights burned out at the same time. I was driving on a rural mountain highway at about 7:30pm and was using my adaptive headlights. They were working fine, I noticed no issues, until they both burned out at the same time. It was dangerous, there was no shoulder to pull over on, and a steep drop-off i couldn't see and no warning whatsoever I'd be in pitch black dark in the middle of the road. Thankfully there was very little traffic, it could have been much worse. My dash camera captured the event and I've shared it to YouTube. https://youtu.be/plJlQYcA8-A No indicator lights ever came on, before or after. I had to drive the last hour to my destination through the mountains in the dark with only fog and running lights. I had been to the dealership for scheduled interval maintenance just the week before. A multi point inspection evidently didn't catch that both headlights were about to go out at the same time. Bulbs? Wiring? Relay? Not sure what happened.

This and other year model RAV4s have a known and reported issue of the tail light lenses not being properly sealed with and connected to the tail light housing. This is allowing water intrusion into the tail light and electrical system and vehicle body. This is the case with both of my tail lights on my 2010 RAV4. Water has been entering the tail lights where the lens is not sealed to the housing. The lack of plastic welding / sealant can be seen at the lens and housing. Water is intruding corroding the electronics and electrical connectors as well as portions of the body. The lenses are becoming deteriorated and discolored due to the water intrusion diminishing the effectiveness of the rear lighting. Of course, this is a safety issue as well as the corrosion of the electrical connectors and electronics within the tail light that may cause them to completely fail. Toyota knows of these issues but refuses to address them.

While operating the vehicle all front headlamps failed simultaneously leaving me in the dark. Dealer next day found both front headlamp bulbs had both low and high beam filaments burned out! This may have been a catastrophic accident but for my fog lights. How can anyone feel safe in a vehicle in which all lights might fail while driving unlit curvy roadways?
