Reliability report · 2021 Hyundai Elantra · Updated July 2026

The redesign fixes the engine and finds seven new recalls — but they are the fixable kind.

This is a clean-sheet Elantra and the change shows in the data. The engine complaints that dominated every year from 2016 to 2020 largely disappear; the 2.0-litre in this car is naturally aspirated and port-injected, which the independent mechanic in our sources rates as a virtue — no turbo, no direct injection, less to go wrong. A hybrid joins the range for the first time.

The cost is a launch-year recall list of seven campaigns. Most are one-visit fixes and several supersede each other, so the count overstates the work: the seat-belt pretensioner story alone accounts for three of them and only the last, 22V354, is the live remedy. Two things to actually plan around: the rearview camera recall, and the hybrid's motor-control software recall for unintended acceleration. Then there is the horn, which fails on these constantly and which Hyundai now covers for 10 years or 120,000 miles.

Canary status

Chirping

What that means: 155 federal complaints across the sedan and the new hybrid, well under half the outgoing car's worst years, and the oil-consumption story that defined the old Elantra is gone. In its place is a launch-year recall pile: seat belts, seats, a windshield, a camera, and on the hybrid an unintended-acceleration software fix. All of them are free dealer visits. The recurring out-of-warranty annoyance is the horn, and Hyundai extended the coverage on that too.

The seat-belt pretensioner recalls — three campaigns, one live remedy

major

This looks worse in a recall list than it is, but only if you know which campaign to look for. A seat-belt pretensioner is the device that snaps the belt tight in a crash, and it works by firing a small pyrotechnic charge. On these cars it may explode on deployment rather than firing correctly, and NHTSA's stated consequence is that it could project metal fragments into the cabin and strike occupants. Hyundai issued 21V796 first, covering 2021 Elantra and Elantra HEV along with the Venue and two Genesis models, with dealers replacing the pretensioners; Hyundai's numbers were 211 and 009G. It then issued 22V218, covering 2021 and 2022 Elantras and the 2020 Accent, number 223. Both were superseded. The campaign that matters is 22V354, which expands and replaces 21V796, 22V069, 22V218 and 22V123 for Accent, Elantra and Elantra HEV vehicles: dealers secure the pretensioner with a cap, free of charge, owner letters went out on 28 August 2022, and Hyundai's number is 229. The campaign text is explicit that cars already repaired under the earlier recalls need the new remedy completed. So a service record showing 21V796 or 22V218 done is not enough — you want 22V354.

Recall 24V879 — the rearview cameramajor

Hyundai is recalling certain 2021 and 2022 Santa Fe, Santa Fe HEV, Elantra and Elantra HEV vehicles, along with 2022 Elantra N and Santa Fe PHEV models, because a damaged printed circuit board may cause the rearview camera image to fail to display. That makes the car non-compliant with Federal Motor Vehicle Safety Standard number 111, the rear-visibility rule, and NHTSA's stated consequence is reduced driver visibility and increased crash risk. Dealers replace the rearview camera free of charge and owner letters were mailed on 14 January 2025. Hyundai's number is 271. Owners in the complaint file describe the failure well — a screen that appears half on and half off, or goes black, worsening with every use — and at least one reports being told the repair had no available solution. Put the car in reverse on the test drive and confirm the camera works, then check the VIN separately, because a working camera today does not mean the recall is closed.

The horn stops working — and Hyundai covers it for 10 yearsmoderate

This is the single most repeated complaint on the new Elantra and it has a genuinely useful answer. Hyundai's bulletin states that certain Elantra, Elantra N and Elantra Hybrid vehicles may experience an inoperable horn, and that the warranty coverage for the horn replacement under this condition has been extended to 10 years or 120,000 miles from original retail delivery or first use, whichever comes first, valid for original and subsequent owners, with instructions to install the latest design. A companion bulletin states the scope as 2021 to 2025 model year Elantra, 2022 to 2025 Elantra N and 2021 to 2025 Elantra Hybrid. The complaint file shows why it exists: owners on their second and third horn, a horn that never worked from purchase, a horn whose fuse blows every time it is replaced, and several who only discovered the fault at the moment they needed it. Press the horn on the viewing — it takes a second, and if it does not sound, that is a free repair for a decade rather than a negotiation. Note that this is a warranty extension, not a safety recall.

Recall 21V302 — seat back reclinersmajor

Hyundai is recalling certain 2021 Elantras because the driver and front passenger seat back recliners may have been improperly welded. NHTSA's stated consequence is that an improperly welded recliner could separate from the seat back frame during a crash, increasing the risk of injury. Dealers inspect and if necessary replace the seat back frame assembly free of charge, owner letters were mailed on 21 June 2021, and Hyundai's number is 204. This is a 2021-only campaign — it does not name the 2022 car, despite one popular video attributing it to that year. Straightforward to close out, and worth confirming given what the seat back is for.

Recall 21V00M — the windshield may not be bonded properlymajor

Hyundai is recalling certain 2020 and 2021 Santa Fe and 2021 Sonata and Elantra vehicles because, during manufacturing, the windshield may not have been properly bonded to the vehicle, allowing it to detach in a crash. Dealers remove and reinstall the front windshield panel free of charge, owner letters were mailed on 20 June 2022, and Hyundai's number is 216. A bonded windshield is structural on a modern car — it helps the roof hold up in a rollover and gives the passenger airbag something to push against — so this is not a glass-cosmetics recall. One thing to watch on a used example: if the windshield has since been replaced for a stone chip, ask who did it and whether the recall was recorded, because the paperwork and the physical car can diverge here.

The hybrid: recall 23V589, and the 12-volt battery that shuts the car downmajor

  • Hybrid (CN7 HEV)

The Elantra Hybrid arrives for 2021 and its 29 complaints are two stories. The first has a recall: 23V589 covers 2021 to 2023 Elantra HEV vehicles where a software error in the motor control unit may cause unintended vehicle acceleration after the brake pedal is released. Dealers update the motor control unit software free of charge, owner letters were mailed on 29 September 2023, and Hyundai's number is 248. Owners describe it vividly — a car surging more than 15 mph above the set speed with a foot off the accelerator, another accelerating against the brakes at a red light — and one reports it recurring a month after the software was applied, which is worth knowing. The second story has no recall but does have a bulletin. Owners get a "Check Hybrid System" warning followed by sudden loss of motive power, sometimes at motorway speed, and restore the car by pressing a 12-volt reset button on the dashboard. Hyundai's bulletin identifies the condition on Elantra, Sonata and Tucson hybrids as diagnostic code P1BB20, 12V Lithium Battery Cell Voltage High, which triggers a warning light and can put the car into limp mode, and prescribes a Battery Management System software update. Dealers frequently cannot reproduce it, so ask whether that BMS update has been applied by name.

Forward radar and driver-assist faultsmoderate

A consistent 2021 cluster with no recall behind it. Owners report the forward radar failing and disabling everything that depends on it — forward collision warning, adaptive cruise control, lane keeping, blind-spot monitoring and rear cross-traffic alert, often all lighting up at once. Several link it to weather, describing the sensors dropping out in rain or snow and sometimes recovering on their own. One records diagnostic code C162078. Hyundai does have a related bulletin for this model year, though it addresses the opposite direction: a transmission control unit update for 2021 Elantras with the 2.0-litre engine and the IVT gearbox, revising the damper clutch logic to address a potential engine stall immediately following Forward Collision Avoidance activation at low engine speed. IVT stands for Intelligent Variable Transmission, Hyundai's name for a continuously variable gearbox — one with no fixed gears. So the safety system intervening and the car stalling are connected on this car, and there is a software fix. Ask whether it has been applied, and on the test drive check that no assist warnings are latched on the dashboard.

Theft risk — a campaign and a settlement, not a recallmoderate

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 after a rise in thefts of 2011 to 2022 Hyundai vehicles not equipped with engine immobilizers and targeted through social media. Every Elantra row carrying these campaigns lists model years 2011 to 2022, so the 2021 is in the population. The related class settlement gives the test you can run yourself: cars built without an immobilizer have traditional turn-key-to-start ignitions, so a push-button-start Elantra is not in this group. These are campaigns and a settlement, not safety recalls, and the software is free. Ask whether 993 has been applied, and note that one Hyundai bulletin warns the software update can make the horn honk on remote start until a separate remote-start module update is done — a different fault from the horn failure above.

The horn never worked since I bought it in August 2023. I've been in countless near accident situations where I was rendered helpless.
