Safety and Driver Assistance Features

Acura RDX FAQ
Does the Acura RDX require premium fuel?
Acura recommends premium unleaded gasoline (91 octane or higher) for all RDX models equipped with the 2.0-liter turbocharged engine (2019-present). Using premium fuel allows the turbo to operate at optimal efficiency, improving both performance and fuel economy. While the vehicle can run on regular fuel in emergencies, long-term use of lower octane can reduce power and efficiency.
What is Acura SH-AWD and how does it work on the RDX?
Super Handling All-Wheel Drive (SH-AWD) is Acura’s performance-oriented all-wheel drive system available on the RDX. It continuously distributes power not only between the front and rear axles but also between the left and right rear wheels. This torque vectoring improves cornering grip, acceleration stability, and all-weather traction, making it one of the most advanced systems in its class.
What are the differences between Acura RDX trims?
The RDX is offered in several trims - Base, Technology, A-Spec, and Advance (and occasionally PMC Edition).
• The Technology Package adds navigation, leather seats, and upgraded audio.
• The A-Spec focuses on sport styling with 20-inch wheels, blacked-out trim, and ELS Studio 3D audio.
• The Advance Package includes luxury upgrades like adaptive dampers, a 360° camera, and ventilated seats.
• The PMC Edition adds exclusive paint and handcrafted assembly at Acura’s Performance Manufacturing Center.
Is the Acura RDX reliable and expensive to maintain?
Yes, the RDX is regarded as one of the most reliable compact luxury SUVs in its segment. Maintenance costs are lower than European rivals like BMW and Audi, thanks to Honda-based engineering and wide parts availability. Routine servicing, oil changes, filters, and inspections; typically occurs every 7,500 to 10,000 miles. Acura’s reliability record and lower repair frequency make the RDX a strong long-term ownership choice.
