Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 10,000 mi; spark plugs every 60,000 mi; coolant every 20,000 mi. The big-interval services (every 20,000 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 2018 model year represents a stabilization point within the second generation, following the 2017 spike that saw two recalls and 664 technical service bulletins, while registering only one complaint and one recall compared to the five-to-six complaint volumes characteristic of 2008-2009. With 578 TSBs, 2018 maintains elevated manufacturer attention compared to 2016’s 188 TSBs, yet sits below the 2017 peak and aligns closely with 2020’s 582 TSBs. The single reported complaint concerns air bags, accompanied by one crash complaint, though the federal data does not specify a causal relationship between these entries. Across the generation, complaint volumes remain minimal in recent production years, with 2018 fitting a pattern of low owner-reported issues and moderate recall activity relative to high service bulletin counts suggesting active factory monitoring. Given its position after the 2017 correction spike and before 2020’s zero-recall year, the 2018 R8 presents a sound acquisition target with statistically low complaint risk and normalized service activity.
