For enhanced safety, the front seat shoulder belts of the Hyundai Sonata are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Mercedes A-Class doesn’t offer height-adjustable seat belts.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Sonata are reminded to check the back seat if they opened the rear door before starting out. The A-Class doesn’t offer a back seat reminder.

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 A-Class doesn’t offer backup collision prevention brakes.

To help make backing safer, the Sonata SEL/SEL Plus/Limited’s cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The A-Class doesn’t offer a cross-path warning system.

Both the Sonata and the A-Class have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, front-wheel drive, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, driver alert monitors, available blind spot warning systems and around view monitors.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its available headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the Sonata the rating of “Top Pick” for 2020, a rating granted to only 30 vehicles tested by the IIHS. The A-Class has not been tested, yet.

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 A-Class’ 4-year/50,000-mile basic warranty expires 1 year and 10,000 miles sooner.

Hyundai’s powertrain warranty covers the Sonata 6 years and 50,000 miles longer than Mercedes covers the A-Class. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the A-Class ends after only 4 years or 50,000 miles.

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

Hyundai pays for scheduled maintenance on the Sonata for 3 years and 30,000 miles. Hyundai will pay for oil changes, lubrication and any other required maintenance. Mercedes doesn’t pay scheduled maintenance for the A-Class.

There are over 2 times as many Hyundai dealers as there are Mercedes 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 A-Class (235/45R18 vs. 225/40R19).

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 A-Class; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed. Some tire options on the A-Class don’t have a run-flat feature, either.
