Known issues on the 2020 Elantra. Three recalls are on federal record for this model year. The first concerns the piston oil rings in vehicles equipped with the 2.0L Nu MPI engine; a damaged engine may stall, increasing the risk of a crash. The second covers the right-side rear wheel lug nuts, which may have been insufficiently tightened; a wheel detaching from the vehicle increases the risk of a crash. The third involves the front lower control arm ball joints, whose fasteners may have been insufficiently tightened; a detached ball joint can cause a loss of vehicle control, increasing the risk of a crash. Owners have filed 313 complaints for the year and Hyundai has issued 89 technical service bulletins. The factory diagnostic and repair procedures behind each of those systems are in this manual.
From diagnosing a stall on the 2.0L Nu MPI engine to torquing wheel hardware or inspecting the front lower control arm ball joints, it keeps you on the OEM procedure and the correct specification for your specific 2020 Elantra.
