2020 Hyundai Elantra Problems

2020 Hyundai Elantra problems owners report most

2020 Hyundai Elantra problems are documented in public: owners have filed 262 complaints with NHTSA, the earliest in 2019 and the most recent in 2026. Sorting those by the component the filer named puts the engine clearly first, at 115 of the 262 complaints, 44 per cent of everything filed.

A complaint is not a repair bill and not a defect finding. It is one owner telling the regulator something went wrong. What makes the count useful is the concentration: when one component takes 44 per cent of everything filed on a car, the pattern is doing more than chance.

Against the 2019 car, this model year has drawn 2 per cent more complaints (262 against 256). Both years are led by the engine, so this is a fault that carried over rather than one introduced with the 2020 car.

Of those complaints, 21 describe a crash and 6 describe a fire. Filers reported 16 injuries. 2 complaints report a death.

Recalls on the 2020 Hyundai Elantra

A recall means the manufacturer or the regulator found a safety defect, and the repair is free at a franchised dealer however old the car is. There are 3 recalls on this model year. Your own car may be covered by some, all or none of them, so check the VIN rather than the model.

In owners own words

These are complaints filed about the engine, quoted as written. They are one persons account rather than a diagnosis, and they are here because a symptom described by a driver is easier to recognise than a component name.

What component or system failed or malfunctioned, and is it available for inspection upon request? The engine malfunctioned, then failed. The vehicle is available for inspection upon request. How was your safety or the safety of others put at risk? I decelerated from 65 mph to exit a freeway. At the end of an offramp, I slowed to a stop sign where the vehicle malfunctioned. It jerked, violently, forward as I attempted to accelerate endangering pedestrians crossing the intersection at the stop sign, other drivers on the offramp, and myself. Has the problem been reproduced or confirmed by a

The vehicle entered limp mode. The Hyundai dealer diagnosed a camshaft problem, said the repair would be covered, ordered the part, and began the work. After the engine was opened, the dealer noted sludge/varnish and denied coverage, claiming lack of maintenance. This VIN is included in safety recall 21V301 for improperly heat-treated piston oil rings on the 2.0L Nu MPI engine. Hyundai told NHTSA that chipped rings can scuff the cylinder bore, cause accelerated oil consumption, knocking, oil-pressure warning, connecting-rod bearing seizure, stall, and in limited cases fire. The published remed

The component which failed was the engine. This engine has been burning oil from the day in which we bought it. This engine puts everyone at risk because it failed in the middle of traffic, and We could have been hit by oncoming traffic. The problem could not be reproduced because the engine tied up in the middle of the road. We had the vehicle towed to the dealer who said it was not covered under the warranty due to abuse. The oil had been changed at the proper intervals, and we are sure the engine failed because it was a poorly made engine. This engine had exactly 69,993 miles when it

Subject: Abnormal Engine Failure – Hyundai Case #[XXX] I am filing this complaint regarding my Hyundai vehicle, which suffered catastrophic engine failure at approximately 150,000 miles. While the vehicle is outside the standard warranty, this type of failure is not consistent with normal use or expected durability. Hyundai Motor America has acknowledged receipt of my certified demand letter (Case #[XXX]) but has refused to provide coverage, instead directing me to pay for towing and diagnostic costs. This position is unacceptable given Hyundai’s history of abnormal engine defects and related

The full breakdown of what owners named when they filed. Components below the top ten are grouped out of this table.

How other model years compare

The same nameplate across the years we hold. Complaint counts fall naturally for newer cars because fewer of them have been on the road for long, so read the column as a rough signal rather than a ranking. In this set the 2017 Hyundai Elantra has drawn the most complaints and the 2021 Hyundai Elantra the fewest.

What to check on the engine

Engine reports range from oil consumption between services to rough running, stalling and a loss of power under acceleration. Oil use is the one owners notice latest, because nothing warns you until the level is already low.

Buying a used 2020 Elantra

Ask for every service record and check the gap between oil changes against the level on the dipstick now. An engine using oil quietly is the most expensive fault on this list and the easiest one to miss on a test drive.

If you already own one

Start a log of oil level between services. A documented consumption rate is what turns a conversation with a dealer from an opinion into a claim, and some manufacturers have covered these repairs well past the warranty.

• Check the oil level and condition yourself before buying.
• Ask for service records covering every oil change.
• Record oil level between services to document consumption.
• Have a compression or leak down test done before a major repair.
