Severity: medium.

What is the 2017-2025 Land Rover Discovery L462 Discovery Air Suspension Height Sensor Failure?

The current-generation L462 Discovery continues the air suspension tradition with its own set of issues. The ride height sensors are particularly prone to failure, giving incorrect height readings that cause the vehicle to sit at uneven heights. The sensors are located at each co… Repairs typically run $300-$800. Severity: medium.
