  • Good fuel economy estimates
  • Some cheap cabin materials
  • Uninspiring handling
  • Ride can feel firm

2015 Acura RLX Overview

Is the 2015 Acura RLX a Good Used SUV?

The 2015 Acura RLX is a decent luxury large car. It boasts top-notch safety scores, reasonable ownership costs for the class, and above-average fuel economy estimates. However, it also has a firmer ride than you’d expect from a luxury car, as well as some cheap cabin materials and a hard-to-use infotainment system.

For 2015, the RLX Hybrid model went on hiatus.

Which Model Year of the Acura RLX Is Best?

The 2015 RLX belongs to a generation that launched for the 2014 model year. The 2015 RLX didn’t receive any significant changes, but later models did.

We recommend starting with the 2017 RLX. For that model year, Acura made several safety features standard, including adaptive cruise control, blind spot monitoring, rear cross traffic alert, and automatic brake assist. Other available features include a surround-view parking camera system and a head-up display. The 2018 RLX gained refreshed exterior and interior styling, a 10-speed automatic transmission (with no improvement in fuel economy), and another standard driver aid called Traffic Jam assist.

If you’re interested in the RLX Sport Hybrid, look for either a 2014 model or one of the 2016-and-newer models. Acura did not produce the hybrid version of this sedan for 2015.

Which Used Acura RLX Model Is Right for Me?

The RLX's sole trim comes standard with a touch-screen infotainment system, a 10-speaker stereo, satellite radio, HD Radio, Bluetooth, a USB port, and Pandora and Aha compatibility. You'll also get synthetic leather upholstery, heated front seats with 12-way power-adjustment, a leather-wrapped steering wheel, proximity keyless entry, push-button start, tri-zone automatic climate control, a moonroof, a rearview camera, lane departure warning, and forward collision warning.

When the RLX was new, it was available with several packages. You might find a model equipped with the Navigation package, which adds a navigation system and GPS-linked climate control. The Technology package adds both features plus a 14-speaker premium stereo, rain-sensing windshield wipers, blind spot monitoring, and leather upholstery. A Krell Audio package gives you everything in the Navigation and Technology packages, plus a 14-speaker Krell stereo system and a power rear sunshade.

Models equipped with the Advance package include all of the above features plus some advanced driver aids, such as front and rear parking sensors, lane keep assist, automatic brake assist, and adaptive cruise control. The Advance package also includes ventilated front seats, heated rear seats, and a heated steering wheel.

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, Tesla, and Infiniti.

2015 Acura RLX Versus the Competition

Which Is Better: 2015 Acura RLX or 2015 Acura TLX?

The 2015 Acura TLX is a luxury midsize car. As such, it doesn’t have as much passenger or cargo space as its larger sibling. Features-wise, these two sedans are similar. However, the TLX has a smaller base engine than the RLX, and it’s mated to an eight-speed automatic transmission. A V6 that makes nearly as much horsepower as the RLX is available. The TLX’s main advantage is price. You most likely will pay several thousands of dollars less for the smaller TLX. Choosing between these two is a matter of preference.

Which Is Better: 2015 Acura RLX or 2015 Lexus GS?

The 2015 Lexus GS is another luxury midsize car. Its V6 engine is nearly as capable as the Acura’s, and the GS Hybrid has an even stronger powertrain. Both the GS and GS Hybrid have higher reliability ratings than the RLX, along with nicer cabin materials, a gentler ride, and more spirited handling. The RLX is likely to be more affordable than the smaller GS – the Acura costs several thousand dollars less on average – but the Lexus is the better pick if your budget allows.

2015 Acura RLX Performance

How Does the 2015 Acura RLX Drive?

The RLX comes standard with a 3.5-liter V6 rated at 310 horsepower and 272 pound-feet of torque. This engine is strong and capable, but it doesn’t stand out compared to the engaging turbocharged or supercharged engines of rivals. The standard six-speed automatic transmission shifts smoothly.

The suspension is tuned to prioritize comfort over athleticism. Shifting the RLX into Sport mode helps it feel a little peppier. Front-wheel drive and Acura’s Precision All-Wheel Steer (P-AWS) come standard. Some critics found the RLX to be agile yet comfortable, while others found its handling too dull and ride too harsh, so this is something you'll want to pay attention to on your test drive.  

Does the 2015 Acura RLX Get Good Gas Mileage?

This vehicle gets an EPA-estimated 20 mpg in the city and 30 mpg on the highway. Those are good fuel economy estimates for the class.

2015 RLX Interior

How Many People Does the 2015 RLX Seat?

This full-size Acura sedan seats five people. Synthetic leather upholstery is standard, as are power-adjustable, heated front seats. Upgrades include leather upholstery, ventilated front seats, heated rear seats, and a heated steering wheel.

There’s plenty of head- and legroom in both rows, but critics were divided on how supportive the front seats are. The same goes for the cabin. Some critics thought it was full of top-notch materials with real wood accents, but others claimed that it wasn’t as luxurious as its German rivals.

How Many Car Seats Fit in the 2015 Acura RLX?

The 2015 RLX has two full sets of LATCH connectors for securing child safety seats.

2015 Acura RLX Features

The RLX features a dual-screen infotainment system with an 8-inch upper screen and a 7-inch lower touch screen. It also has HD Radio, satellite radio, a 10-speaker sound system, a USB port, Bluetooth, and Pandora compatibility. Other standard features include tri-zone automatic climate control, push-button start, proximity keyless entry, and a moonroof. A navigation system, a 14-speaker premium stereo, and a 14-speaker Krell sound system are available.

The infotainment system is a mixed bag. Operating some functions, including the navigation system, is easy; others, such as the climate controls, can be tricky to figure out. Additionally, the touch screen’s graphics are dull compared to what the competition offers.
