Service bulletins for the 2018 Land Rover Discovery

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

887 on file from NHTSA, as of 2026-10-19.

SSM740692018-11-26. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. Customers are reporting poor air conditioning performance which retailers are subsequently diagnosing as due to a faulty air conditioning compressor.
SSM739452018-11-13. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; EQUIPMENT:APPLIANCE:AIR CONDITIONER. Issue: When performing a software update on the HVAC (Heating Ventilation and Air Conditioning Control Module) the update fails stating SDD (Symptom Driven Diagnostics) has failed to resolve software.
N151NAS32018-11-13. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER.
