What owners report
Owners of this model year most often describe engine knocking or internal failure, engines that stall or shut off while driving, and oil consumption that needs frequent top-ups. Oil use is described as building up over months or years, while stalls and internal noises are often described as sudden, sometimes at highway speed. Mileage is missing from most of these complaints, and where it is given, reports range from under 1,000 miles to about 115,000 miles.
- Engine
Engine knocking, ticking, or internal failure
- 21 complaints (41%)
- median 32,000 mi at 4.2 yrs old (3 state mileage, few)
- 1 mention a crash, fire or injury
- filed 2021–2026
Owners describe ticking or knocking that becomes louder, sometimes followed by a loud bang, and then the engine loses power or stops. Some complaints describe rod bearing or timing chain failure, metal pieces in the oil, or a bad cylinder head found by the dealer, and several say the engine needed replacement. Owners also report long waits before a dealer could inspect the car, and one says the manufacturer declined to cover an engine swap, citing ownership and mileage. Where mileage is stated, these engine failures are reported from about 32,000 to about 115,000 miles, and many complaints give no mileage.
What to check: Ask whether the engine bearing inspection and the knock sensor software campaign listed for this model year have been completed, and have a technician check for ticking or knocking noise.
2 excerpts from owner complaints in NHTSA records
“I was driving on a the interstate going 75 MPH when I heard a loud thumping noise from the front right side, I lost power steering, power brakes and the car shut off. I had to struggle to maneuver and stop the car to the emergency lane. It was then towed to the dealer that discovered the timing chain failed. The timing chain also damaged other internal parts throwing fluid throughout the engine and causing metal shards from other internal components. The car has 32k miles and less than 3 years old.”
NHTSA complaint #11399096, filed 2021-03, 32,000 miles“We were driving the car and all of a sudden it would only go 30 mph and starting making a noise, pulled over and car would not go anymore. I took to a shop authorized from my carmax care program and it was diagnosed as rod bearings broken in the engine. This is a know issue with this model and Hyundia extended the warranty due to know issue. …”
NHTSA complaint #11487951, filed 2022-10 - Engine
Engine stalls or shuts off while driving
- 20 complaints (39%)
- median 10,000 mi at 1.3 yrs old (7 state mileage, few)
- 1 mention a crash, fire or injury
- filed 2018–2026
Owners describe engines that stalled or shut off while driving, often at highway speed, and sometimes after all dashboard warning lights came on. Some say the engine would not restart or the car could not accelerate after the shutdown, and some describe losing power steering and power brake assist. One owner was told the fuel pump may be the problem, and another describes a dealer replacing a fuel-related part after keeping the car for 23 days. Where mileage is stated, these shutoffs range from 87 miles to about 60,000 miles, and many complaints give no mileage.
What to check: Ask for repair records for any stalling, starting, or fuel pump work, and test drive the car at highway speed to confirm it runs and restarts without warning lights.

“Car shut off while on the highway randomly started shaking. All lights turned on check engine,motor oil light battery light. Car shut off to the point where I couldn't accelerate. So imagine being on the highway and your car shuts off randomly while your in motion and cant accelerate to merge to the emergency lane. This happened 4 more times on my way to the dealership less then 800 miles!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!”
NHTSA complaint #11130331, filed 2018-09, 800 miles“I bought a 2018 Hyundai gt sport 3 months ago. Since day one car has been stalling and having a hard time starting. I was on the highway doing 75mph and the car just turned off no warning. I called the dealer in my area let them know about the starting issues and the stalling issues with the car I took it in to them few days later. They kept it for 3 days and told me sorry we do not know what to tell you. Took it home and that day the car stalled on my way home. …”
NHTSA complaint #11185997, filed 2019-03, 87 miles - Engine
Engine burns oil and needs frequent top-ups
- 13 complaints (25%)
- median 106,112 mi at 7.2 yrs old (1 states mileage, few)
- filed 2022–2026
Owners describe excessive oil consumption, with oil dropping between changes and no visible leak to explain it. Some add oil weekly or every 600 to 800 miles, and one says the dipstick showed no oil at an oil change. A few say the oil warning light stayed off, or came on only when the oil was nearly gone, and some describe stalls or failures after the oil ran out. Where mileage is stated, these complaints describe cars from about 55,000 to about 106,000 miles, and owners describe the oil loss building up over months or years.
What to check: Check the dipstick level and ask for oil change records that show how much oil was added between changes. Ask whether the oil consumption inspection and combustion chamber cleaning bulletins for this model year have been performed on the car.

“It uses a lot of oil with no visible leak or reason. I put new oil in all the time. All the time! For two years since buying it used. Warning light does not come on till it's out. Car is hot, of course, and stops running in the middle of the road. I see there is a recall on some elantras for oil piston seals but not this car. Seems it should be.”
NHTSA complaint #11670888, filed 2025-07“I have noticed over the last year or so that the engine was burning oil. This was indicated by Express Oil Change multiple times during oil changes, including today. The oil level today didn't even register on the dipstick, so it seems this is getting worse. I can get oil change records on request from the above company.”
NHTSA complaint #11527719, filed 2023-06 - Forward collision avoidance
Collision warning and braking system faults
- 8 complaints (16%)
- median 27,000 mi at 2.6 yrs old (2 state mileage, few)
- filed 2019–2026
Owners describe collision-warning systems that stop working, show warnings, or go out of calibration, sometimes with a message that the system needs checking. Others describe automatic braking that did not respond, and sudden braking at slow speeds in heavy traffic with no dashboard warning. One complaint describes an ABS failure light, with cruise control and auto hold warning lights also staying on, and another describes air felt in the brake pedal, which the dealer said was a faulty brake booster. Most of these complaints do not state mileage, and the brake booster complaint lists about 18,000 to 22,000 miles.
What to check: On a test drive, check that the collision-warning, ABS, and braking warning lights stay off and that the brake pedal feels firm. Ask for records of any dealer calibration or brake repair work on the car.

“The aeb system does not show any warnings or attempt to stop the car. I do not drive around trying to make this feature work but after getting the new car I did realize it was not detecting anything while my other car detects and stops fine in the same scenario. I have gone to the Hyundai service center where I purchased the car about this as well as submitted a case with Hyundai corporate. Corporate response was: go back to the service center again and tell them what my concern is (again). So, I did. …”
NHTSA complaint #11176420, filed 2019-02“On 6/27/24 while starting my car in the morning an ABS failure light came on, various other system failure lights came on and have stayed on since that day including Cruise Control and Auto Hold. My car only had 33,250 miles on it! I purchased for an OBDII Reader hoping the failure was just a Wheel Speed Sensor. Unfortunately, the error code registered in the ECU was C240201 “Motor Failure” I brought in my car to a very reputable Auto repair shop, and for a $139 diagnosis fee, they confirmed that the ABS Motor / Pump had failed. …”

Buying note. Buyers may want to check the oil level and oil change records, test drive for stalling or unusual engine noise, and ask about the engine bulletins for this model year. Because several complaints involve engine replacement, a pre-purchase inspection by an independent mechanic is a practical step.
Summary written with AI from a sample of 48 NHTSA complaints for this model year (picked at random, with complaints that state a mileage and recent ones taken first), then checked automatically against the source records. Where a problem shows a complaint count, every complaint for this model year was matched with fixed keyword rules (written with AI and tested against the sample), and the mileage, age and repair figures are calculated from those complaints; owners' figures are as stated, not verified. Other counts refer to the sample.

Example complaints
Engine: “My vehicle has 55,000 miles, and the engine completely stalled while I was driving to the dealership to get it looked at. I had my oil change done 01/04/2024, and barely drove it since I dropped it off 01/11/2024. After weeks of waiting on any update, I was finally contacted that today, 01/26/2024, my car had no oil and this is why my engine failed. I have video evidence of the oil change, and the dealership is trying to place blame on the mechanic that has done the oil change. …”

I brought it to Murfreesboro Hyundai (TN), where they confirmed the oil was low and started an oil consumption test. A bearing clearance test (BCT) was also performed and passed. After back-and-forth over several weeks, I was told the oil consumption was within spec, but the dealership stated Hyundai would cover all necessary repairs, including a combustion chamber cleaning, under warranty. I was told this work was completed and the vehicle was returned to me. In July 2025, the exact same flashing CEL returned. …”
