2017 Toyota RAV4 exterior lighting problems

“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”

“The contact owns a 2017 Toyota Rav4. The contact stated that after turning the vehicle off and later attempting to restart the vehicle, the vehicle failed to restart. The battery was then recharged. The failure occurred on several occasions before the vehicle was taken to the local mechanic. The local mechanic was unable to diagnose a failure or determine a cause for the failure. Additionally, after opening the rear hatch door, the door failed to close and remained open. The contact stated that water and condensation were present inside the rear brake light assembly. The cause of the failure was not yet determined. The manufacturer was not contacted. The failure mileage was 30,000.”

“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?”

“The contact owns 2017 Toyota Rav4. The contact stated while driving downhill at night with the headlights illuminated, the windshield darkened, and the contact lost visibility of the roadway. The vehicle was taken to the dealer, who informed the contact that the windshield was compliant to safety standards. The contact stated that he had contacted an unknown dealer, who informed him that the failure was related to the design of the headlights. Additionally, the contact stated that while attempting to turn the key in the ignition switch, the key would not turn and remained stuck. The contact stated that he continuously attempted to turn the key while wiggling the steering wheel, and he was able to turn the key in the ignition switch. There was no warning light illuminated. The manufacturer was notified of the failure and a case was opened; however, no further assistance was provided. The vehicle was not repaired. The failure mileage was approximately 5,000.”

“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.”
