Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 21,000 mi; spark plugs every 63,000 mi; coolant at 105,000 mi. The big-interval services (at 105,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 2021 Land Rover Discovery shows a notable improvement over its immediate predecessor: complaints dropped from 18 in 2020 to 10, recalls fell from 6 to 4, and TSBs decreased from 494 to 457. This trend continued into 2022, which recorded only 7 complaints and 4 recalls, suggesting the model year addressed some prior reliability concerns. The generation-wide data reveals a sharp spike in complaints and TSBs beginning in 2016 (the new generation introduction), peaking around 2018-2019, then declining steadily through 2021 and beyond. The 2021 model's top complaint areas center on electrical system issues, with no crash or fire complaints recorded. Given this trajectory, 2021 represents a relatively stable point in the generation's reliability arc—better than 2020 but not yet reaching the lower complaint levels of 2022—which makes it a reasonable purchase provided a thorough pre-purchase inspection verifies the electrical components, as that remains the persistent fault area.
