5/5 Overall
NHTSA 5-Star Safety Rating
For the 2024 Elantra, electrical issues and driver-assistance system behavior make up the bulk of what owners report. On the electrical side, horn failure is the most frequently described problem, owners report the horn becoming intermittent and eventually stopping working entirely, with some pointing to the underhood fuse panel area as the source. The forward collision avoidance and lane departure systems each draw a notable cluster of complaints, with owners describing false alerts triggering under normal driving conditions, particularly the driver attention warning prompting rest breaks unprompted and lane-keeping alerts firing when the vehicle is tracking straight. A smaller number of owners also report brake-related concerns, including rotors warping and rear brake wear occurring earlier than expected, sometimes progressing to metal-on-metal contact around 35,000 miles.

Recalls 2 and 3 describe the same EGR valve defect — I'll treat them as one issue.
The 2024 Hyundai Elantra has 3 recalls, the most serious affecting hybrid models: the hybrid power control unit can overheat and catch fire.
The hybrid power control unit sits at the heart of the hybrid drivetrain, managing power flow between the engine, battery, and electric motor. When it overheats, the risk of a fire in the engine bay rises, and this recall applies only to hybrid-equipped Elantras. The second recall affects the exhaust gas recirculation valve, a component that routes a portion of exhaust gases back into the engine. If the valve develops an electrical short, it can cut drive power without warning while the vehicle is moving, leaving the driver without propulsion and raising the risk of a crash.
