2020 Hyundai Elantra · 6th Gen Refresh (2017-2020)

2020 Hyundai Elantra Problems: Owner-Reported Issues, Recalls & Common Fixes

The 2020 Elantra is the final year of the AD2 generation and uses the 2.0L Nu MPI engine with the IVT (Intelligent Variable Transmission, a CVT). The Nu is NOT a Theta II GDI engine, so the headline oil consumption / engine seizure recalls do not apply - but some oil consumption is still reported. IVT software has had several updates.

✅ Better Than Reputation Suggests

The 2.0L Nu MPI avoids Theta II GDI issues. Most complaints are software (IVT calibration) and minor accessories. Confirm any IVT TSB has been performed.
