1
Active Height Control (AHC) Systemmajor~90,000-150,000 mi

2
Brake System Componentsmoderate~25,000-50,000 mi

90,000

Elevated Risk Zone

While still very robust, at 90,000 miles, components like the Active Height Control system's accumulators or lines could begin to show signs of age. Accessory belts and hoses should be inspected carefully. This mileage often signifies th…

120,000+

High Risk Zone

At this mileage, the LX is still expected to perform reliably, but it's where the most significant potential wear items like the AHC pump or the entire system might require costly attention. Proper maintenance history becomes paramount,…
