How Much Does the 2018 Acura RDX Cost to Own?

The 2018 RDX’s five-year costs for gas, insurance, repairs, and maintenance are projected to be $28,735, or $5,747 per year. That’s above below average for a luxury compact SUV.

Is It Better to Buy a Used or New RDX?

The 2018 RDX was the last model of its generation, as Acura completely redesigned their smallest SUV for the 2019 model year. The redesigned model includes plenty of changes. The 2019 RDX replaces the V6 engine with a turbocharged four-cylinder that's nearly as powerful and more fuel-efficient. There are styling upgrades inside and out, and the new RDX feels more luxurious than the 2018 model.  The new RDX also comes with more standard features, like a much larger infotainment screen, Acura's new True Touchpad Interface (TTI), and lane departure warning. Pricing for the 2019 RDX starts at $37,400.

Shopping for an older RDX can save you money – potentially thousands of dollars. If you can’t afford the redesigned 2019 RDX, have a look at the 2016, 2017, and 2018 RDXs. They are virtually identical. You can purchase the older model and get the same basic features as you will in the 2018.

What Does Acura's Certified Pre-Owned Warranty Cover?

Acura offers a certified pre-owned program for cars six years old or less and with fewer than 80,000 miles. Eligibility is determined by the vehicle’s initial sale date. Qualifying vehicles get a limited warranty that is good for up to two years or 100,000 miles after the four-year/50,000-mile new-car warranty has expired. Acura covers the powertrain for seven years or 100,000 miles. These CPO models must pass a 182-point inspection. Additional benefits are available, including roadside assistance and the first scheduled maintenance, so read Acura’s warranty page carefully.

Among luxury car manufacturers, Acura’s CPO program is about average, according to our research. You’ll find better programs from Lexus, Audi, and Infiniti.

2018 Acura RDX Versus the Competition

Which Is Better: 2018 Acura RDX or 2018 Mercedes-Benz GLC?

The 2018 Mercedes-Benz GLC sits high in our luxury compact SUV rankings for many reasons. First and foremost, the GLC has a strong claim for the nicest interior in the class. The cabin is replete with premium materials, there are two rows of spacious seats, and few rivals come with as many standard features. The GLC offers multiple powertrains, including a high-performance engine and a plug-in hybrid.

Which Is Better: 2018 Acura RDX or 2018 BMW X3?

The 2018 BMW X3 joins the RDX near the top of the class rankings because it, too, is a well-rounded crossover. The X3 offers multiple engines, including turbocharged and diesel options, and it handles better than most class rivals, including the RDX. Inside, the X3 is classy and comfortable, and it has a more user-friendly infotainment system than its Acura rival.

2018 RDX Interior

How Many People Does the 2018 RDX Seat?

The 2018 RDX seats five people in two rows. The front seats are comfortable and remain supportive, even on long drives. The rear seats are among the most expansive in the class, and unlike most small crossovers, the RDX can seat 6-foot passengers in both rows.

Standard seating features:

  • synthetic leather upholstery
  • heated front seats
  • 10-way power-adjustable driver's seat

Available seating features:

  • genuine leather upholstery
  • sport seats
  • ventilated front seats
How Many Car Seats Fit in the 2018 Acura RDX?

The 2018 RDX has two complete sets of LATCH car-seat connectors on the rear outboard seats and an upper tether on the rear middle seat. The lower anchors are fairly easy to use, though they're set a bit deep in the seat. The tether anchors are mostly problem free, except for the middle tether. It's on the ceiling, and attaching a car-seat strap to it can block the driver's rearward view when in use.

2018 Acura RDX Features

The Acura's infotainment system isn't as easy to use as many rival systems. The base system doesn't have a touch screen, but you can control it using a knob and several buttons on the center stack. This infotainment setup has quite a learning curve. The upgraded system adds a second display, which is an 8-inch touch screen, eliminating many of the physical buttons. Despite the streamlined controls, this version is no easier to use than the base system.

  • Standard infotainment features: a 5-inch display screen, a seven-speaker premium sound system, Bluetooth, a USB port, satellite radio, and Pandora
  • Available infotainment features: an additional 8-inch touch screen, a 10-speaker premium audio system, an enhanced media interface, voice recognition, and navigation
  • Additional standard features: a moonroof, a proximity key, push-button start, and dual-zone automatic climate control
  • Other available features: GPS-linked climate control system
