2021 Toyota Sequoia Suspension Problems

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.
