Is the Acura RDX high maintenance?

By CarWhere Research · Updated November 7, 2026

Acura doesn't publish service prices, so we don't put a dollar figure on the RDX (AAA's mainstream compact SUV (FWD) average, for context, is $1,746 a year). Acura Maintenance Program covers 1 year / 12,000 miles. Owners filed 0.541 NHTSA complaints per 1,000 RDXs sold (2015–2022 sales), #14 of 26 SUVs we rank (lower is better; segment median 0.533).

RDX maintenance cost: 5 and 10 years

Acura doesn't publish service prices, and AAA's benchmark is built from top-selling mainstream models, so applying it to a Acura would understate the cost. We don't put a dollar figure on it. For scale only: AAA's 2025 benchmark for mainstream compact SUV (FWD) models is $1,746 a year (11.64¢ a mile), and the all-vehicle average is $1,656. The best predictors of what you'll spend are the factory schedule below, the length of any included maintenance and the complaint record.

How the verdict is set: Two inputs. Cost: the estimate against AAA's $1,656 all-vehicle average (more than 3% under counts in the car's favor, more than 3% over against it). Complaints: NHTSA owner complaints per 1,000 sold against the median of every model in our study (0.48); well under the median helps, well over hurts, roughly double or more hurts twice as much. Both low = "No"; both high = "Yes". Models without a dollar estimate get no verdict.

Oil changes

Normal service: Condition-based: Maintenance Minder calculates remaining oil life (shown as %); 'due soon' at 15%, 'due now' at 5%, negative distance once past due. If no message appears within 12 months of the last reset, change oil yearly.

Severe or special conditions: No separate fixed severe interval — Maintenance Minder adjusts to operating conditions; specific severe-use footnotes listed under schedule.

How the RDX compares in its AAA category (compact SUV (FWD))

Same AAA category means the same dollar benchmark, so the complaint rate is what separates them. Luxury models aren't priced.
