NHTSA 5-Star Safety Rating
Engine complaints dominate the 2021 QX50 owner reports, with multiple drivers describing serious internal issues, most notably metal particles or debris found in the engine oil during service. Some owners also report loud noises coming from the engine followed by the vehicle failing to restart, pointing to mechanical failure rather than minor wear. A secondary cluster of complaints involves the forward collision avoidance system, where owners describe unexpected behavior from the driver assistance features. A separate but recurring pattern involves door latch and door-ajar sensor problems on both the driver and passenger sides, owners report persistent "door open" warnings while the door is fully closed, alarm activation in the middle of the night, and occasional difficulty opening the affected door.
