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 BMW 3 Series Sedan 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 3 Series Sedan doesn’t offer a back seat reminder.

Both the Sonata and the 3 Series Sedan have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, driver alert monitors, available blind spot warning systems, around view monitors 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 3 Series Sedan’s 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 BMW covers the 3 Series Sedan. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the 3 Series Sedan ends after only 4 years or 50,000 miles.

There are over 2 times as many Hyundai dealers as there are BMW 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 3 Series Sedan (235/45R18 vs. 225/35R20).

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 3 Series Sedan; 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 3 Series Sedan don’t have a run-flat feature, either.

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.
