The QX55’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

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 Sorento Hybrid are reminded to check the back seat when a sensor determines the back seat is occupied. The QX55 doesn’t offer a back seat reminder.

The Sorento Hybrid’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 QX55 doesn’t offer a driver alert monitor.

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

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 Sorento Hybrid the rating of “Top Pick” for 2021, a rating granted to only 136 vehicles tested by the IIHS. The QX55 has not been tested, yet.

The Sorento Hybrid comes with a full 5-year/60,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The QX55’s 4-year/60,000-mile basic warranty expires 1 year sooner.

Kia’s powertrain warranty covers the Sorento Hybrid 4 years and 30,000 miles longer than Infiniti covers the QX55.

The Sorento Hybrid has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced.

If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed.
