Top Issues to Watch
- ENGINE (98)
- ELECTRICAL SYSTEM (39)
- POWER TRAIN (28)
Generation & Refresh (US)
2018 is year 2 of the Sixth generation (AD).
- Redesigned for the 2017 model year.
- A refresh arrives in 2019.
- 6th generation Elantra (US).
What this means for buyers
Year 2 is typically a safer pick than the first model year — early issues are more likely to be identified, but the platform is still new.
If you're comparing prices, check 2017 (redesign year) vs 2018+ pricing and recalls.

Should You Buy the 2018 Hyundai Elantra?
Reliability is good for this model year, and it sits well above average among 2018 sedans. Within the Elantra lineup it lands in the middle of nine scored years, and the 2019 rates about the same. Independent repair-cost data puts yearly repairs for the model at $452, under $526 for its class. The federal crash-test rating is 4 of 5 stars.
The weak point is the engine. Owners report sudden failure: stalling at speed, knocking, or seizing, often with no low-oil or check-engine warning first. Many describe heavy oil burning, with a quart added every 600 to 1,000 miles. Failures show up between about 55,000 and 77,000 miles, and dealers then call for a replacement engine. Four complaints involve fire. Second owners report denied warranty claims. The one federal recall covers the electrical system and visibility.
Ask the seller for oil-change and engine repair records, and check the oil level yourself. On the test drive, hold highway speed and note any swaying, since some owners report it. The 2019 is a reasonable alternative to compare.
Compared to the 2019 Hyundai Elantra, which scored 2 points higher.

Used Buying Checklist
Key things to inspect or verify before purchasing a 2018 Hyundai Elantra.
Pull the dipstick before the test drive; a low level points to oil burning that precedes engine failure.
Ask for oil change receipts and any dealer oil consumption test or engine replacement records.
Listen at idle and under acceleration for ticking or knocking from the engine.
Scan for stored trouble codes, especially cylinder misfires, and confirm the check engine light stays off.
Drive at 70 mph on grooved pavement and note whether the car wanders in its lane.
Turn the wheel fully both ways, parked and reversing, and watch for binding or a power steering warning.
Inspect hood and roof paint for bubbling or peeling, especially on white cars.
Confirm the airbag warning light goes out after startup and stays off when sliding the passenger seat.
2018 Hyundai Elantra Common Problems by Component
309 owner complaints grouped by vehicle system.
ENGINE
98 complaintsSafety-relatedSudden engine failure is the main pattern. Engines stall at speed, knock, or seize, often with no low-oil or check-engine warning first, and dealers then call for a replacement engine. Many reports describe heavy oil burning, with owners adding a quart every 600 to 1,000 miles or finding the oil nearly gone before the next change. Failures show up between about 55,000 and 77,000 miles. Four complaints involve fire, including smoke and flames after a loud pop on the highway. Owners disagree on recall coverage, and second owners report denied warranty claims.
UNKNOWN OR OTHER
41 complaintsSafety-relatedThis category is a mix. The largest thread repeats the engine story: random shutoffs while driving, a flashing check-engine light, and oil found nearly empty between changes with no warning light. Other reports cover peeling paint with rust starting on the hood, overheating after coolant hoses wore out, and a drain plug that fell out and wrecked the engine. Safety complaints include a car stolen and crashed, a trunk with no inside release that trapped a child's hand, and blind-spot and automatic braking systems that fail to detect vehicles.
ELECTRICAL SYSTEM
39 complaintsSafety-relatedStalling while driving leads this category, including one shutoff at low speed that ended in a crash. Several reports tie stalls and engine fires to oil disappearing between changes, and one car burned while parked and turned off in a garage at 40,000 miles. Owners describe misfire codes that return after new plugs, coils, injectors, and wiring. Other faults include an ABS pump failure with multiple warning lights, an airbag light triggered by moving the passenger seat, dead climate controls and lights, and a rear door that would not open from inside.
POWER TRAIN (28 complaints)
POWER TRAIN
28 complaintsSafety-relatedMost complaints here are engine failures, not transmission faults. Cars stall in traffic, restart with loud knocking, and crawl at 10 to 30 mph before dying. Shops find broken rod bearings or metal in the oil, often under 80,000 miles, and one repair quote topped $16,000. Second owners report Hyundai refusing the powertrain warranty. Dual-clutch cars hesitate and lose power pulling away from a stop, with one clutch failing at 117,000 miles. One fire broke out while the car was being towed in neutral, injuring the owner.
STEERING (16 complaints)
STEERING
16 complaintsTwo problems dominate. At highway speeds around 70 mph, the car sways and wanders in its lane, worse on grooved or wet pavement and in wind. New tires, alignment, and a tie rod do not fix it, and dealers call it normal. Separately, the steering locks up or turns very heavy with the power steering warning light on, then works again after a restart. Dealers diagnose a steering column replacement, with one failure at about 83,000 miles. Several theft reports are also filed under this heading.
EXTERIOR LIGHTING (11 complaints)
EXTERIOR LIGHTING
11 complaintsBulbs burn out again and again, mainly the brake lights, tail lights, high-mount brake light, headlights, and license plate lights. Some owners report replacing the same bulb several times, and one found melted brake light wiring. A false check-brake-light message appears even when the lights work. Headlights set to auto shut off while driving at night, and parking lights cycle on and off with the car locked. Many owners also say the low beams aim too low, leave a dark shadow ahead, and fail to light road signs.
STRUCTURE (11 complaints)
STRUCTURE
11 complaintsPeeling paint makes up nearly every report. Paint bubbles, cracks, and flakes off the hood and roof in large, growing patches, sometimes down to bare metal, within three to four years. White and Pearl White cars come up most, though silver is also mentioned. Owners say Hyundai extended body coverage from 3 to 5 years without telling them, and dealer claims often stall. Rust follows where paint is lost. One report describes violent wind buffeting with only the rear windows down at 55 mph.
AIR BAGS (9 complaints)
AIR BAGS
9 complaintsSafety-relatedSerious crashes end with no deployment. Six of the 9 complaints involve a crash and three report injuries. Reports include a side impact that spun the car, a highway pileup that crushed both ends, and a deer strike at 55 mph, all with nothing deploying. In one case the bags inflated but stayed in their housings. Other owners report the airbag warning light coming on without a crash, including at 33,000 miles and within a week of buying the car from a dealer.
SERVICE BRAKES (8 complaints)
SERVICE BRAKES
8 complaintsSafety-relatedThe brakes fail to stop the car hard enough in emergencies. Owners describe a soft, spongy pedal that has to be pumped, a car that keeps rolling under full pedal at 55 mph, and skidding with a firm pedal at 65 mph. One near miss is logged as crash-related. A hissing pedal led to a faulty brake booster diagnosis at 18,000 miles. Other reports describe sudden harsh stops at low speed in traffic and an automatic emergency braking and forward collision warning system that does not work.
VEHICLE SPEED CONTROL (8 complaints)
VEHICLE SPEED CONTROL
8 complaintsThe car stops responding to the gas pedal for a few seconds with no warning lights, then picks up again. Dealers often cannot reproduce it and find no trouble codes. Other reports describe full stalls in traffic and on the highway, sometimes with the oil found empty. Cruise control creeps 3 to 7 mph above the set speed and resists slowing down. One driving school reports sudden acceleration with the student's foot on the brake. Repeat ignition coil failures follow an engine replacement in another case.
