2020 Toyota 4runner Suspension Problems

Your 4Runner's X-REAS suspension system may fail at relatively low mileage (around 45,000 miles), causing loss of vehicle stability and control, especially at high speeds or during emergency maneuvers. This unpredictable suspension failure creates a serious safety risk that could lead to accidents. The repair will likely involve inspection and replacement of suspension components within the X-REAS system.

Your front coil spring fractured at around 53,000 miles and needed replacement. Toyota covered 50% of the repair cost after you brought it in for a routine inspection. The repair typically involves removing and replacing the damaged coil spring.

When you shift your 4Runner's differential from high (H4F) to low (H4L) range, the dashboard indicator light stays yellow instead of turning green like it did on your previous 4Runner model. You're concerned this yellow light indicates a warning or defect in either the differential locking mechanism or the dashboard electronics. The dealer says this yellow color is normal for this model year, but your owner's manual suggests yellow means a warning condition.
