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 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.

In the 2015 model year, the RC350 generated several complaints focused on seats (2 reports), the electrical‑system‑related seat issues (2 reports), plus a few “unknown/other” and exterior‑lighting items, while registering no crash‑ or fire‑related complaints. By comparison, the next two years saw only a handful of total complaints—one in 2016 and two in 2017—indicating that the 2015 model experienced a higher incidence of reported problems than its immediate successors. Recall activity remained at zero for both 2016 and 2017, and investigations stayed constant at one per year, suggesting that none of the 2015 issues escalated to mandatory action. The trend therefore places 2015 at the higher‑end of the complaint arc within the generation, though the problems are limited to non‑safety components. **Takeaway:** the 2015 RC350 is not a red‑flag year for safety‑related defects, but the elevated seat‑related complaint count suggests buyers should verify interior condition and warranty coverage before purchase.
