2021 TOYOTA HIGHLANDER Visibilitywiper Problems

This is a supplemental complaint to add more detail to a prior submission. I am the original owner of a 2021 Toyota Highlander with 10,000 miles at the time of the issue worsening to the point that I finally broke down and was forced to pay the Toyota dealership's hefty diagnostic fee. The air conditioning system has failed due to a refrigerant leak in the rear A/C lines, specifically near the exhaust area under the vehicle. The dealership diagnosed the issue and quoted me over $3,000 to replace “all necessary components in the rear.” They offered no coverage or goodwill repair despite the vehicle’s age and mileage. Upon researching the issue for longer than a year at this point, I discovered far too many similar complaints from other Highlander owners (years 2019–2021) describing identical failures — typically rear A/C lines corroding, cracking, or leaking prematurely. In some cases, customers were...

Vehicle windshield glass has a distorted and wavy quality that impacts visibility for the driver. I have contacted the dealership about this issue and there is not a current recall for the windshield. The windshield says Toyota Pilkington laminated acoustic heated [XXX] , DOT15. I purchased this vehicle in the last week and did not notice the distortion on the short test drive. At first, I thought it was a reflection issue from the dash, but it is not. This should be investigated and remedied. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

We purchased 2021 highlander in March 2021. Since the day we experienced some vibration in the driver side mirror and we first notice bad vibrations when we drove above 40 to 50 mph. We never bought this up with Toyota or the dealer untill May 5th 2023. When we created a case with Toyota, they directed us to the dealer. Once we scheduled the service they confirmed the vibration and replaced Part Number: 879400E351. After the replacement we noticed that the vibrations are getting bad even during lower speeds now. The mirror is vibrating during idle and any speed higher than 30/ 40mph. We scheduled another appointment with the dealer and the manager did test drive another highlander 2022 model and confirmed that it is also vibrating. It was surprising to see that all the highlanders have these mirror vibrations. They said eventhough theres is vibration, it'd be considered normal. I...

The driver side mirror wiggles at highway speed or with strong wind and the image in the mirror is not clear which causes the driver to do a double take on where and how far the car is. This is a safety issue that needs to be addressed and fixed by Toyota. I’m not the only one experiencing this issue, see other reports. Thanks for your quick action on this matter.

While driving my 2021 highlander on the road my Driver side mirror shakes alot. It makes my visibility shaky when im trying to switch lanes. I took the car to toyota and newer models are having same issue the toyota dealer told me

Visibility for interior windows defroster/defogger is not functioning. Inside windows are fogging up and icing no matter what heating setting is used. This poses significant risk of visibility in all windows. I have had to try to defrost the inside of my windows just to see out of my side windows and see in my rearview mirror. I have not gone to the dealership, but do intent to. No warning messages present.

Driver side mirror vibrates and gets worse on the interstate and windy days. It does not give clear, steady view. Night time all you see is shaking headlights. It’s highly distracting and discomforting to eyes and causes headaches. Taken it to dealership plenty of times. It was replaced one time and still same issue. Dealership contacted Toyota about the issue and still no solution.

Since purchasing this 2021 Highlander Platinum in July 2021, the glass of the side mirrors are always 'shaky' at speeds above 40mph. The dealer has replaced the glass, which did not improve the issue. They then replaced the entire mirror assembly, which still has not fixed the issue. The mirror is shaky/jittery enough to make it difficult to look into while driving prior to changing lanes.

THERE IS DEFECT IN THE TOYOTA HIGHLANDER PLATINUMS' DRIVER SIDE MIRROR. THE MIRROR GLASS WILL VIBRATE LEFT AND RIGHT WHEN DRIVING. IT DISTORTS THE IMAGE IN THE MIRROR. WHEN ON HIGHWAY, IT IS VERY NOTICEABLE. THIS KIND OF VIBRATION SHOULD ONLY OCCUR IF YOU DRIVE OVER THOSE POTHOLES OR RIPPLE ON THE YELLOW DOUBLE SOLID LINES OR SHOULDER OF ROAD. I HAVE TEST DRIVEN MULTIPLE ONES OF THE SAME TRIM ON THE DEALERSHIP'S LOT TO TRY TO GET DEALERSHIP TO LOOK INTO REPLACING/FIXING MY MIRROR, BUT THEY ARE SAYING ITS A CHARACTERISTIC OF THE VEHICLE SINCE THE OTHERS ARE DOING IT. ALSO TEST DROVE A LIMITED TRIM AND THE VIBRATION WAS WORST THAN THE PLATINUM. I HAVE NOT HAD THIS ISSUE WITH OTHER 4 WHEEL CARS. TOYOTA WILL NOT ADDRESS THIS ISSUE JUST BASED ON MY COMPLAINT SO I AM PUTTING THIS COMPLAINT SO HOPEFULLY TOYOTA WILL ADDRESS THE ISSUE.
