On the 2015-2022 Land Rover Discovery Sport, like most Land Rover models, the Discovery Sport suffers from panoramic sunroof drain blockages that cause water to enter the cabin. The long drain tubes running from the front sunroof tray down to the A-pillars and from the rear tray to the C-pillars become blocked with debris. The sunroof seal can also deteriorate, allowing water past even with clear drains.

This issue also affects: Audi A5 Sportback, Ford Bronco Sport, Jeep Grand Cherokee L

Common Symptoms

Water dripping inside the cabin during or after rain
Wet headliner
Damp carpets in footwells
Musty smell
Water stains on A or C pillars

How to Fix

Clear all sunroof drain tubes with compressed air (never use a wire). Inspect and replace the sunroof seal if deteriorated. Clean the sunroof tray of debris and leaves. Apply a thin bead of silicone sealant along the tray edges if the factory seal has failed.

On the 2015-2022 Land Rover Discovery Sport, the wiring harness that runs through the tailgate hinge area on the Discovery Sport chafes against the body structure as the tailgate opens and closes. Over time, individual wires break or short out, causing intermittent failures of the rear wiper, rear wash, license plate lights, tailgate release, and backup camera. The rubber grommet protecting the wires deteriorates.

This issue also affects: Ford Transit Connect, MINI Hardtop 4 Door, Volkswagen Tiguan

Common Symptoms

Rear wiper stops working intermittently
Backup camera cuts in and out
License plate lights not working
Tailgate release button unresponsive
Multiple rear electrical faults simultaneously

How to Fix

Inspect the tailgate wiring harness where it passes through the hinge area. Repair any broken wires and wrap the harness with additional protective sleeving. Replace the rubber grommet with the updated JLR part. In severe cases, the entire tailgate harness may need replacement.
