Service bulletin NAS20.02.002

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.

NHTSA's summary

A potential issue has been identified on certain Land Rover vehicles within the listed Affected Vehicle Range where the warranty period for certain items in the Owner's Handbook may be incorrect. The 12V startup battery warranty period for all listed vehicle lines and the bumper-to-bumper warranty period for Discovery and Range Rover Velar (only) may not contain the correct details. The correct warranty period is 4 years or 50,000 miles (whichever occurs first) for both items.
