2024 Toyota Grand Highlander Wipers & Visibility Problems

Your front windshield defroster isn't working evenly—the driver's side clears normally, but the passenger side takes 15-20 minutes longer to defrost and doesn't clear properly, making it unsafe to drive. Toyota and the dealer have confirmed the problem through testing and thermal imaging but are claiming this is normal operation. Getting the defroster repaired will likely involve inspecting the heating ducts, blend door actuators, or heating element distribution to the passenger side of the windshield.

Your windows fog up heavily while driving, especially in cool or humid weather, affecting your windshield and side windows. Even when you turn the defrost to full blast with fresh air intake, the fogging doesn't clear quickly enough. This forces you to constantly fiddle with climate controls or pull over to wipe the windows manually, creating a visibility hazard.

Your panoramic moonroof suddenly shattered while you were driving, with no apparent cause like road debris or impact from another vehicle. This created a safety hazard since glass fragments could have injured you or your passengers. The issue may require moonroof glass replacement and an inspection of the moonroof assembly to determine why it failed.

Your windshield has visible wavy distortions in the glass that make it hard to see clearly while driving. You're concerned these distortions might affect your car's safety features and find them distracting. The windshield is acoustic heated glass made by Pilkington. The issue likely requires windshield replacement to restore clear visibility and ensure safety systems function properly.

Your moonroof suddenly shattered with a loud bang while you were driving, scattering glass into thousands of pieces. There was no crash or impact that caused this to happen. The moonroof glass will need to be completely replaced.

Our vehicle is less than 2 months old, and it had less than 5,000 miles before highway debris (gravel) chipped and cracked the windshield on two separate occasions. I have never had a chip or crack caused by rocks before, and my previous vehicles have been hit plenty of times.
