Is the 2020 Hyundai Elantra a bad year?
255 owner complaints to NHTSA. Engine complaints: 111, 6.9× a quiet Elantra year.
Keep it, but watch the engine
The engine draws 6.9× the complaints of a quiet Elantra year, but the 2020 is still young: half of its engine complaints so far came in by 38k miles, and that mark will move as owners add miles. Check your powertrain warranty first.
The verdict moves with mileage: the same car reads differently at 30,000 and at 150,000 miles.

Recalls for the 2020 Hyundai Elantra: 3
The piston oil rings may not have been properly heat-treated, which could result in engine damage. A damaged engine may stall, increasing the risk of a crash. In addition, oil may leak onto hot exhaust components, increasing the risk of a fire.
The lower control arm ball joint fasteners may have been insufficiently tightened allowing the ball joint to detach from the lower control arm. A detached ball joint can cause a loss of vehicle control, increasing the risk of a crash.
The right-side rear wheel lug nuts may have been insufficiently tightened, allowing the wheel to detach from the vehicle. A wheel detaching from the vehicle increases the risk of a crash.
A recall may cover only some cars of a model year; the campaign size counts every model and year it lists. Enter your VIN at nhtsa.gov/recalls: dealers fix open recalls free.
