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 at 120,000 mi; coolant every 50,000 mi. The big-interval services (every 50,000 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 2020 4Runner sits in a markedly improved phase of the fifth generation, recording just 31 complaints and a single recall against a backdrop of steadily declining federal actions since the generation's 2010 launch (145 complaints, 12 recalls). Compared to the immediately preceding years — 2018 (57 complaints, 5 recalls) and 2019 (64 complaints, 4 recalls) — the 2020 model year shows a sharp drop in reported issues, while TSB volume at 157 remains moderate but well below the generation's 2014 peak of 417. The data doesn't specify root causes for the leading complaint categories (Unknown/Other, Service Brakes, Steering, Suspension), though crash-involved complaints total only four with zero fire reports. Subsequent years 2021–2023 maintain similarly low complaint levels (30–39) and recall counts (1–3), confirming a stable, mature platform. This positions the 2020 as one of the cleanest federal records in the model's 36-year history, making it a strong candidate for a used purchase with minimal documented safety or reliability flags.
