2022 Toyota 4runner Suspension Problems

Your 4Runner's XREAS suspension system failed at 36,000 miles, causing unusual vibration and side-to-side roll when turning on the highway that made the vehicle harder to control. Toyota has refused to cover the repair because it's outside the warranty period. Fixing this will likely involve replacing the failed suspension components in the XREAS system.

Your tires wore out prematurely at 45,000 miles instead of the expected 70,000 miles, with excessive wear on the inside edges despite regular rotations every 5,000 miles. After replacing the tires, an alignment check revealed that your front struts were sagging. This suspension issue likely caused the uneven tire wear and may need to be addressed to prevent further damage.

Your right CV joint is moving up and down, and after the engine warms up, it loses its proper alignment, causing your steering wheel to shake. The shaking only stops when you pull off the highway, and it completely disappears when you switch to 4-wheel drive. The dealer has acknowledged the shaking during road tests but claims it's normal, though you believe this makes the vehicle difficult to drive in a straight line.
