Is the 2020 Hyundai Elantra reliable?

The 2020 Hyundai Elantra has 252 owner complaints on file with NHTSA, 1.3 times the median of 201 for 2020 sedans on this site.

At a glance

Next to the 2019 and 2021
At 36 complaints for each year on the road, the 2020 runs close to the 2019 (31) and above the 2021 (22).
Top problem
Two problems run close. Stalling has 37 complaints and engine failure has 35, out of 252 in all. A quarter of the 21 owners who gave a mileage for stalling saw it by about 8,000 miles, and half by about 44,000.
Crash, fire and injury reports
24 of the 252 complaints (10%) report a crash, a fire or an injury. The typical vehicle on this site sits at 6%, so this one runs well above it. Counted separately (one report can carry more than one), 21 reports mention a crash, 6 mention a fire and 16 people were hurt. The reports record 2 deaths.
Recalls behind the top problems
stalling, engine failure and misfire all have recalls on the same system, and the same campaigns cover them: 21V-301. A recall on the same system doesn't always cover the failure owners describe, so compare its summary with the complaints.
When owners filed
Filings peaked in 2021 at 48 (full calendar years only). In 2025 there were 39. So far in 2026, 47 more have come in.

        How this compares

        2020 Hyundai Elantra252
        Median 2020 model here (75 vehicles)219
        Median 2020 sedan here (14)201

        252 complaints is 1.2 times the median 2020 model on this site and 1.3 times the median 2020 sedan. Among the 9 Elantra model years here it ranks 6th for complaints. Counts follow sales volume as much as reliability, so a truck that sells 700,000 a year draws more reports than a sedan that sells 200,000.
