The engine is covered. The gearbox is the new question.

New for this model year in our data and the reason 2020 does not simply inherit 2019's report. IVT stands for Intelligent Variable Transmission, which is Hyundai's name for a continuously variable transmission — a chain-belt gearbox with no fixed gears. The independent mechanic in our sources describes it plainly on the later car: it is a no-frills CVT, chain-belt driven, very simple, and physically tiny, about a third the size of a Corolla's. Owners of the 2020 report it failing. One documents a recurring automatic transmission failure producing three complete vehicle shutdowns during active driving, two of them at motorway speed. Another bought the car at 67,000 miles, drove 22,000 more and had the check-engine light come on for the transmission. A third is on their third transmission in three years of ownership. Hyundai's own bulletins for the 2020 Elantra are unambiguous about the severity: they instruct dealers to perform a transmission control unit update and, if necessary, replace the IVT, listing transmission codes P0730, P0731, P0741, P0867 and P1603 and engine codes P0106, P0068 and P0101. The useful counterweight is a later bulletin covering 2020 to 2023 cars, which tells dealers that certain IVT fault codes can be fixed by replacing the oil pressure sensor rather than the entire transmission assembly. If a shop quotes you a gearbox on a check-engine light, that bulletin is the thing to ask about first.

Two assembly-line campaigns, both about fasteners that were not tightened enough, and both with severe consequences. In 19V720, the right-side rear wheel lug nuts may have been insufficiently tightened, allowing the wheel to detach from the vehicle; it covers 2019 Ioniq Hybrids and 2020 Elantras, dealers inspect and if necessary tighten the nuts free of charge, the recall began on 15 November 2019 and Hyundai's number is 184. In 19V721, the lower control arm ball joint fasteners may have been insufficiently tightened, allowing the ball joint to detach from the lower control arm, which NHTSA says can cause a loss of vehicle control; dealers inspect and as necessary tighten the fasteners free of charge, the recall began on 20 November 2019 and Hyundai's number is 185. Both are quick, free inspections rather than parts jobs, which means there is no excuse for either to be open. Run the VIN.

A distinct 2020 cluster with no bulletin behind it. Owners describe headlights failing progressively — one bulb goes, it gets replaced, then the other goes, then a different bulb in the same housing — and one filing states the headlights failed because they were soldered incorrectly. Another reports the high beams stopping work after two years while the regular lights still function, with the indicator on the dashboard illuminating but no light coming out. A further owner describes total headlight failure escalated to Hyundai's executive case management. The same complaint recurs on the 2021 and 2022 cars, so this is not a one-year quirk, but there is no Hyundai bulletin covering it in the Elantra file, which means it is a repair you pay for. Check low beam, high beam and daytime running lights individually before you buy, at night if you can.

Several 2020 owners report the reversing camera showing a black screen, sometimes intermittently and sometimes permanently, in one case alongside the lane-assist system switching itself off. There is no Hyundai bulletin covering it on this model year in the Elantra file, and the later rearview-camera recall covers 2021 and 2022 cars rather than this one, so treat it as a complaint-sourced fault you would pay to fix. It matters practically because a rear camera is required equipment on this vintage, so a dead one is both a safety item and an inspection problem in some states. Put the car in reverse during the test drive and confirm you get a picture.

The signature everyday fault of this generation and it is covered. Hyundai's bulletin states that certain Elantras may have an internal or external door handle that is inoperative or requires repeated attempts to open the door, and that warranty coverage for the door latch was extended to 10 years with unlimited mileage from original delivery, valid for original and subsequent owners. The 1A-Auto mechanic covering the 2017 to 2020 cars puts this first on his list and begins his video unable to get into the vehicle, noting the rear doors are most often affected and the repair means stripping the door. Test all four doors from both sides, several times.

Hyundai's bulletins describe Campaign 993, an anti-theft software upgrade with window decals, alongside Campaign P32 for steering-wheel locks and Campaign 9A5 for a reinforced ignition-cylinder protector, launched in response to a rise in thefts of 2011 to 2022 Hyundai vehicles not equipped with engine immobilizers, targeted through social media. A related class settlement notes that vehicles built without an immobilizer have traditional turn-key-to-start ignitions, which is a test you can run at the kerb. Every Elantra row carrying these campaigns lists 2011 to 2022, so the 2020 is in the population, and one 2020 owner's complaint is a theft report. These are campaigns and a settlement, not safety recalls, and the software is free. Ask whether 993 has been applied; if not, book it, and ask about the reinforced ignition-cylinder protector too.

2020 is the final year Hyundai sold the Elantra GT, a hatchback on a different platform and a separate NHTSA model. None of the 241 complaints or three recalls in this report belong to it, and every record was checked to confirm no GT rows are folded in. The GT's engine paperwork is genuinely different and more generous — its connecting-rod-bearing warranty extension runs through model year 2020, and it has a knock-sensor campaign the sedan does not. If you are cross-shopping the five-door, read it as a separate car with a separate history.
