2010 Toyota Highlander headlight problems

EXTERIOR LIGHTING

Headlamps become cloudy and burn out new, expensive bulbs in months. Internet search says Toyota is aware of problem, but prior to my search my dealership wanted to charge me hundreds of dollars to 'evaluate electrical system'

EXTERIOR LIGHTING:HEADLIGHTS:BULBS

I purchase The H4 LED’s from headlightexperts.com February 2022. There is a design flaw with their H4.bulb. The low beam have LED’s on both sides of the light bulb, however the halogen bulb has a shield so that light will only come out of one side of the bulb. The result of leds on both sides of the low beam is light hits the high beam reflector from the back side of the low beam led bulb, and blinds oncoming vehicles. When I contacted customer service via email, they kept saying I have the bulb at the wrong angle, and sent me links to 2videos for proper installation. I keep adjusting the bulb, at first with 45degree turns but then even less- still the light from the back side of the low beam bleeds onto the high beam reflector and blinds oncoming vehicles due to this design flaw. When I called the companies Phone number [XXX] it links to their sales department only. I attempted to explain the issue to their salesman who salesman who proceeded to dismiss the concern as my fault for not installing it correctly. There is no way to install this product correctly due to the fact it has low beam leds hitting a high beam reflector. When I pointed out the safety issue this product creates, I was told to look elsewhere for “some unicorn bulb that doesn’t exist.” He was rude, Hostile and argumentative.. When I attempted to explain the design flaw issue again, he selected would talk over me saying “bla bla bla bla bla” when ever I spoke like a 4yr old. In short there was ZERO concern for public safe their product puts at risk. I have included photos of both sides of their product showing high and low beam leds on both side of the bulb, as well as photos of a standard halogen bulb with the metal shield to prevent any spillage of low beam light onto a high beam reflector- INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

EXTERIOR LIGHTING

THE BACK UP LIGHTS ON MY HIGHLANDER ARE ALMOST NON EXISTENT. I HAVE TRIED TO USE THEM TO BACK UP AT NIGHT AND THERE IS NOT LIGHT AT ALL. YOU CAN BARELY SEE ANYTHING AT NIGHT USING THESE "BACK UP LIGHTS" I FEEL THIS IS A SAFETY HAZARD. I LIVE OUT IN THE COUNTRY AND NEED THESE BACK UP LIGHTS TO SEE ANY OBSTRUCTION AT NIGHT. I TOOK THE HIGHLANDER TO MY MECHANIC AND HE SAID THAT WAS JUST HOW TOYOTA MADE THESE BACK UP LIGHTS. I FEEL THIS IS INSUFFICIENT AND DANGEROUS WHEN TRYING TO BACK OUT OF MY DRIVE WAY AT NIGHT. I CANNOT BELIEVE NO ONE HAS ADDRESSED THIS PROBLEM .

EXTERIOR LIGHTING

WHEN STATIONARY OR DRIVING, DASHBOARD DOOR-OPEN LIGHT STAYS ON. ALL DOME LIGHTS STAY ON WHEN DRIVING UNLESS TURNED COMPLETELY OFF ON DASHBOARD BUT THEY WILL STILL FLICKER AND WARNING SOUND WILL GO ON AND OFF WHEN DRIVING, TURNING A CORNER, OR GOING OVER A BUMP ON ANY ROAD. WHEN LOCKING THE CAR WITH THE DOOR-REMOTE, THE WARNING SOUND GOES ON AND STAYS ON UNTIL CAR IS UNLOCKED. CAR MUST BE LOCKED BY HAND TO STOP WARNING SOUND. CAR WAS SENT TO TOYOTA REPAIR CENTER FOR ELECTRICAL REPAIRS, BUT THIS WARNING LIGHT ISSUE WAS NOT REPAIRED. THERE IS A BUMP IN THE REAR HATCH FROM BACKING UP IN A GARAGE. SERVICE DEPT. SAID REAR DOOR NEEDED TO BE REPAIRED BECAUSE REAR HATCH WOULD NOT CLOSE CORRECTLY. HOWEVER, REAR HATCH HAS ALWAYS CLOSED AND STILL CLOSED. TOYOTA COULD NOT GUARANTEE A NEW HATCH OR REPAIRED BODY WORK WOULD FIX THE PROBLEM. WARNING LIGHTS PROBLEM STARTED MONTHS BEFORE REAR DOOR ISSUE. TOYOTA OFFERED TO TURN WARNING SOUND OFF, BUT I FEEL IT IS A SAFETY ISSUE. I ROUTINELY CHECKED IF ANY DOOR IS OPEN.
