2021 Toyota Sequoia — Known Issues & Recalls

While your Sequoia was parked with the driver door open, it suddenly began reversing on its own despite being in Park, even though you weren't inside the vehicle. You rushed to the driver's seat but couldn't stop the reversal, and the vehicle collided with a creek bed, causing you to sustain injuries. The dealer was unable to reproduce the problem when they inspected it, but this appears to be a potential issue with the transmission or shift lock mechanism that allowed the vehicle to move from Park without driver input.

Your gas tank developed a crack and started leaking without any accident or impact damage. You discovered the leak after the vehicle had been parked for about 6 hours. The fuel tank will likely need to be replaced or professionally repaired to seal the crack.

Your sunroof suddenly shattered with a loud bang while you were driving on the freeway. The dealership claimed a rock caused the damage, but you found no rock inside the sunroof when you checked. This appears to be a manufacturing defect rather than impact damage, but the dealership refused to help or investigate further. The repair will likely involve replacing the entire sunroof glass panel and frame.

Your driver side suspension shock is making creaking, grinding, or knocking noises when driving over small bumps or road imperfections at low speeds, and you can reproduce the sound by bouncing the vehicle up and down. You're concerned the suspension components may fail prematurely or under stress. Toyota was unable to replicate the noise during inspection, but you've identified a related Technical Service Bulletin from similar 4Runner models with comparable suspension systems. Resolving this will likely involve Toyota inspecting and potentially replacing the driver side shock absorber or related suspension components.
