NHTSA 5-Star Safety Rating
Complaints for the 2021 Hyundai Accent cluster around three systems. Seat belt complaints lead the count, with multiple owners describing belts that fail to restrain properly or behave unexpectedly during normal driving. Wheel and lug nut issues are the second most-reported concern, owners describe lug nuts breaking or shearing off during tire service, with several noting the problem occurred at authorized dealerships during routine rotations. Engine and starting complaints round out the picture: owners report intermittent no-start conditions where the engine cranks but won't catch, as well as brief, unexpected losses of power while driving at highway speeds. The no-start issue appears to recur across multiple attempts before dealers can observe it directly, making diagnosis difficult. A handful of owners also mention sudden power loss lasting several seconds during acceleration or deceleration in traffic.

The 2021 Hyundai Accent has 4 recalls, the most serious being seatbelt pretensioners on both the driver and passenger sides that can explode in a crash and send metal fragments into the cabin, striking occupants.
A loose bolt in the steering column can allow the column to detach from the steering rack entirely, leaving the driver with no ability to steer the vehicle. On the brake side, the master cylinder may have been built with sharp internal edges that cut into the oil seal over time, causing brake fluid to leak past the seal and reducing braking force. This can result in a longer brake pedal stroke and a noticeably extended stopping distance before the vehicle comes to a halt.
