NHTSA 5-Star Safety Rating
Engine and powertrain complaints dominate the 2020 Elantra's complaint set. Owners frequently report erratic RPM behavior, revs climbing and falling on their own without any throttle input, along with hesitation during acceleration and rough or interrupted shifting. Some describe the vehicle lunging or surging unexpectedly, both while moving and from a stop, often with the check engine light coming on. Transmission-related reports echo the engine complaints, with owners noting gear engagement problems and inconsistent power delivery, particularly on cruise control. The third most-reported area is exterior lighting, where owners describe repeated headlight bulb failures in short succession, followed by unresponsive connectors and high beams that stop engaging, leaving minimal usable light at night.

By System
The 2020 Hyundai Elantra has 3 recalls, all rated at the same severity level, with the most serious being an engine defect where the piston rings can cause the engine to stall or leak oil onto hot exhaust components, raising the risk of fire.
On the chassis side, two separate fastener issues affect the suspension and wheels. The lower front control arm ball joint may not have been tightened properly and can detach, causing sudden loss of steering control. The right-side rear wheel lug nuts may also be insufficiently tightened, allowing the wheel to separate from the vehicle while driving.
