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 oil rings can degrade, causing the engine to stall or leak oil onto hot exhaust components and start a fire.
The other two recalls both involve fasteners that may not have been tightened sufficiently at the factory. On the suspension side, the lower front control arm ball joint can work loose and detach entirely, which removes the connection between the wheel assembly and the suspension and causes an abrupt loss of steering control. Separately, the right rear wheel lug nuts on certain vehicles may also be under-torqued, allowing the rear wheel to detach from the vehicle while driving. Both of these conditions create crash risk with little warning to the driver.
