Over 200 people are killed each year when backed over by motor vehicles. The Sonata Limited has standard Reverse Collision-Avoidance Assist that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The ILX doesn’t offer backup collision prevention brakes.

The Sonata Limited has a standard Around View Monitor to allow the driver to see objects all around the vehicle on a screen. The ILX only offers a rear monitor.

The Sonata’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The ILX doesn’t offer a driver alert monitor.

Both the Sonata and the ILX have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, available blind spot warning systems and rear cross-path warning.

The Sonata comes with a full 5-year/60,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The ILX’s 4-year/50,000-mile basic warranty expires 1 year and 10,000 miles sooner.

Hyundai’s powertrain warranty covers the Sonata 4 years and 30,000 miles longer than Acura covers the ILX. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the ILX ends after only 6 years or 70,000 miles.

The Sonata’s corrosion warranty is 2 years longer than the ILX’s (7 vs. 5 years).

There are over 3 times as many Hyundai dealers as there are Acura dealers, which makes it much easier should you ever need service under the Sonata’s warranty.

For better traction, the Sonata SEL Plus/Limited’s tires are larger than the largest tires available on the ILX (235/45R18 vs. 225/40R18).

The Sonata has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the ILX; it requires you to depend on roadside assistance and your vehicle will have to be towed.

The Sonata has a much larger trunk than the ILX (16 vs. 12.4 cubic feet).

The Sonata’s standard folding rear seats are split to accommodate bulky cargo. The ILX’s standard single piece folding rear seat is not as flexible; long cargo and a passenger can’t share the rear seat.

To make loading groceries and cargo easier when your hands are full, just waiting momentarily behind the back bumper can open the Sonata SEL/SEL Plus/Limited’s trunk, leaving your hands completely free. The ILX doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.

The Sonata uses gas struts to support the hood for easier service access. The ILX uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

The Sonata Limited’s standard easy entry system glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The ILX doesn’t offer an easy entry system.

The Sonata Limited has a standard heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The ILX doesn’t offer a heads-up display.

The Sonata’s power parking brake sets with one touch and releases with one touch. The ILX has a lever-type parking brake that has to be strenuously raised to engage properly. It has to be lifted up more and a button depressed to release it.

While driving with high beams on, sensitive light sensors standard on the Sonata detect other vehicles which could be blinded and automatically switch to low beams. The ILX doesn’t offer automatic dimming high beams.

Standard air-conditioned seats in the Sonata Limited keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The ILX doesn’t offer air-conditioned seats.

Both the Sonata and the ILX offer rear vents. For greater rear passenger comfort, the Sonata has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The ILX doesn’t offer rear air conditioning vents, only heat vents.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Hyundai Sonata (except SE) offers an optional wireless phone charging system (Qi) in the center console. The ILX doesn’t offer wireless personal charging.

The Sonata Limited’s Remote Smart Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Remote Smart Parking Assist will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The ILX doesn’t offer an automated parking system.
