2026 Toyota Grand Highlander — Known Issues & Recalls

Your brand-new Grand Highlander's front windshield cracked on its own while parked, with no obvious cause. You've noticed other owners reporting the same issue, with some mentioning poor installation or recracks after replacement. The windshield may need to be professionally removed and reinstalled with proper sealing and mounting techniques.

Your new Grand Highlander is producing a loud booming and echo sound inside the cabin when you drive between 25–40 mph, which creates a pressure sensation in your ears and causes nausea and disorientation. This problem appeared almost immediately and is severe enough to make the vehicle unsafe to drive. The issue may be related to cabin resonance, wind noise sealing, or acoustic insulation and will likely require dealer inspection and repair of the affected components.

Your car produces a loud, uncomfortable booming noise inside the cabin when driving over bumps at speeds below 40 mph. This is a noticeable resonance issue that occurs during low-speed driving over uneven road surfaces.

Your panoramic sunroof suddenly exploded outward while driving on the highway, sending glass onto your passenger in the middle seat. You had to pull over quickly for safety. This appears to be a manufacturing defect that needs investigation and repair of the sunroof assembly.

Your digital dashboard display went completely black when you tried to start your car, leaving you unable to see your gas level and other important information. The infotainment screen and heads-up display continued working, so you could still see your speed. After turning the car off and restarting it about 15 minutes later, the dashboard display returned to normal and has worked fine since. The issue may involve a loose electrical connection, software glitch, or a failing dashboard display unit that may need inspection or replacement.

Your electronic parking brake sometimes fails to release when you shift into gear, and the brake warning light stays on. This has happened multiple times in your first 2,000 miles of ownership. The dealership has refused to repair or replace parts without being able to reproduce the problem in their shop, even though you've provided photos of the issue.
