Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2015 RC300.
The 2015 Lexus RC300 is a passenger car equipped with an Automatic (AV-S6) transmission, achieving an EPA-rated 40/39/40 mpg that anchors its efficiency profile. The model year carries a notably light reliability footprint, with only six total owner complaints and a single recall logged, service brakes representing the most common concern. That places the 2015 RC300 as a clean point in the model's reliability record, with no concentrated issues beyond the brake area to define it. For researchers, the result is a stable reference year whose minimal complaint volume suggests few widespread problems during this production run.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
Owner complaints about the 2015 Lexus RC300 top in one area — the service brakes, 1 of 6 reports (17%), well ahead of the next concern. None of this vehicle's 1 recall campaigns target the service brakes, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 1 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the service brakes pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
