Significant rust and corrosion on the frame and undercarriage, potentially compromising structural integrity. This is a critical safety risk and a major concern for long-term ownership. Some owners report extensive rust even on low-mileage vehicles. Preventative treatments and regular inspections are highly recommended. Estimated repair cost: $1,500 - $10,000+.

Steering Shimmy/Vibration

A common issue where the steering wheel shakes or vibrates, typically at highway speeds (50-70 mph). This can persist despite tire balancing and alignment. It's often linked to worn steering components, wheel balance issues, or tire wear. Estimated repair cost: $200 - $2,500.

Seat Belt Retractor Issues

Recalls and complaints have highlighted issues with front seat belt retractors mounted in the rear access doors. Cracks in the door panel due to forceful closing can lead to detachment, compromising seat belt function. This poses a moderate safety risk. Estimated repair cost: $0 - $500.

Sinking Seat Syndrome

Some owners report the driver's seat sinking or falling at an angle while driving, which can affect driving control and seat belt fit. Toyota has acknowledged this as a common issue but has not developed a definitive repair. Estimated repair cost: $0 - $1,500.
