What owners report
Owners of the 2021 Elantra most often describe two kinds of trouble: driver-assistance warnings that switch off forward collision avoidance and smart cruise control, and electrical faults such as a horn that stops working, a dead door lock actuator, or a backup camera that fails. A separate group of complaints on this model year is paperwork-related, with owners saying seat-belt recall parts were unavailable long after the notice arrived. Reported mileages in the sample range from a few hundred to over 125,000, so the sample mixes delivery-day faults with higher-mileage engine and transmission reports.
- Forward collision avoidance
"Check Forward Safety System" warning disables cruise
- 25 complaints (19%)
- typically at 2.9 yrs old
- 1 mention a crash, fire or injury
- filed 2021–2025
Owners describe a dashboard warning telling them to check the forward safety system, often together with a check smart cruise control message, appearing while driving on a highway or open road with nothing in front of the car. After the message appears, smart cruise control and automatic braking stop working, and in some cases the warning goes away after a week or a restart and then returns. Complaints mention dealers resetting or recalibrating the front radar or camera, replacing the radar unit, quoting several hundred dollars for realignment, or telling owners that replacement parts are on back order. Reported across a wide mileage range in the sample, including cars with well under 15,000 miles, and most often described on highway trips.
What to check: Ask the seller to start the car and confirm no forward safety or smart cruise control warnings appear, and request any service records for front camera or radar calibration. A service bulletin covers front camera calibration and warning-light conditions on these vehicles, so ask whether it was applied.
2 excerpts from owner complaints in NHTSA records
“One day I was on the highway driving and the front collusion safety warning appeared. I thought the warning went off because the sensor was dirty due to dead bugs. However, I pulled over and the sensor did not appear dirty. After awhile the sensor went off on its own. Then a few weeks late the front collusion safety warning appeared again while I was driving on the highway. The warning has not fixed itself. I cannot use my cruise control. …”
NHTSA complaint #11603543, filed 2024-07“I was driving using cruise control when suddenly I got the error message “Check Forward Safety System” and my cruise control no longer functions. Turned car off and back on and message is still there. As the emergency braking system stopped working, this is a safety issue. Have not taken it to dealer yet. The car has other software/electrical issues related to the reverse camera and Apple CarPlay. There seems to be several software issues with this car.”
NHTSA complaint #11510150, filed 2023-03 - Seat belts
Seat-belt recall parts unavailable / pretensioner recall
- 23 complaints (17%)
- typically at 1.8 yrs old
- 1 mention a crash, fire or injury
- filed 2022–2026
A run of complaints on this model year are about recall 22V354000, which concerns front seat-belt pretensioners that may explode on deployment. Owners state they received the notice but were told the repair parts were not yet available, and that weeks or months passed without a remedy. A few complaints describe belt-related problems directly, including a rear belt that would not retract and a front belt issue at higher mileage. Complaints were filed mainly during 2022, close to the recall notice; mileages are generally not stated.
Recall 22V354000Recall 22V218000Recall 21V796000
What to check: Check the VIN against NHTSA recall lookups for 22V354000, 22V218000 and 21V796000 and confirm with the seller that the seat-belt pretensioner remedy has been completed.

NHTSA complaint #11465920, filed 2022-05 - Engine
Stalls, no-start and loss of power (engine)
Mentioned in 8 of 60 sampled complaints
Owners describe the engine shutting off without warning, sometimes at speed or while the stop-and-go idle feature is engaged, with a message to shift to neutral or park and restart. Several report the car then would not restart and had to be towed, and dealers in some cases could not reproduce the fault. Others describe a knocking sound at idle, fluctuating RPM, an illuminated check engine light, and higher-than-expected oil consumption. Spread from roughly 5,000 miles up to about 127,000 miles in the sample, with several reports around 60,000 miles and above.
What to check: Ask for a cold start and listen for idle knock or stalling, and check the oil level and whether oil changes were kept up to date. Service bulletins describe oil-consumption inspection and cold-start procedures, so ask whether either was performed.

“Engine shots off while on the automatic stop and go idle . It is being doing it for a while but it is happening more often even with the auto idle off and it even happened at the freeway. It gives me a message to put it in park or neutral and turn the engine on manually. Making this a very dangerous situation because cars behind me don’t know that my engine suddenly shots off. Thanks”
NHTSA complaint #11678266, filed 2025-08“While Driving the car suddenly turns off. It puts me at risk because if I am in a situation where there are other cars, I can be hit and undangering my life and others! This problem happened suddenly and the car restarted only to fail again,multiple times. Towed to dealer /Danbury Hyundai and they claim not to find problem. The car had a full tank of fresh gas. This happened without warning.”
NHTSA complaint #11447230, filed 2022-01 - Electrical system
Camera, radio and door-lock electrical faults
- 37 complaints (28%)
- median 1,314 mi at 0.5 yrs old (2 state mileage, few)
- 1 mention a crash, fire or injury
- filed 2021–2026
Complaints describe the backup camera image failing, which some link to dashboard lights and radio flickering, and one owner reports a door lock actuator stuck so the door would not lock or close with the key fob. Others mention Apple CarPlay dropping repeatedly and the infotainment system rebooting while driving. Dealers confirmed a faulty camera in at least one case but had no explanation for the remaining symptoms. Reported from a few hundred miles to about 60,000 miles, with no clear weather or seasonal pattern in the sample.
Recall 24V8790001 related service bulletin
What to check: Test the backup camera, each door lock with the fob, and a phone connection through CarPlay during a test drive; ask whether recall 24V879000 for the rearview camera has been performed.

“Wireless phone projection while using apple iphone xr continuously drops while using maps feature. When it disconnects I have to push two buttons on screen. Ok and then the button to reconnect. Sometimes this happens as much as every 5 seconds. I have nearly crashed while trying to constantly reconnect. Especially when I am in an area I do not know. There is no option to connect carplay via usb wired connection. This issue feels like a safety issue. As it is very distracting while driving.”
NHTSA complaint #11395046, filed 2021-02, 2,123 miles“car problems started with back up camera not working, it has caused dash lights to go out, headlights to go out while driving safety sensors to sound for no reason. I have also started having problems with radio flashing and going blank. The vehicle has been checked by Hyundai dealer they did say back up camera bad but no answers for rest of issues.there were no warning lights prior to any of these problems. I still do not know what is really wrong and cannot drive vehicle at night or bad weather for fear of losing headlights. …”
NHTSA complaint #11491030, filed 2022-10 - Electrical system
Horn stops working
- 10 complaints (8%)
- typically at 3.8 yrs old
- filed 2022–2026
Several owners state that the horn simply stopped making sound, some within the first year of ownership, and that fuse replacement did not resolve it in at least one case. Complaints say dealers and independent mechanics treat it as a known condition on this model, and one owner reports repeated horn replacements. Hyundai issued warranty extensions for the horn assembly on 2021-2025 Elantra and Elantra Hybrid vehicles, and owners describe using that coverage. Reported within the first months to about a year of ownership in the sample; mileages are mostly not stated.
What to check: Press the horn with the car on before buying, and ask the dealer whether the horn warranty extension applies and whether the horn has already been replaced.

“My vehicle has been in the shop here at McGrath Hyundai in Chicago, IL 30+ times since I bought it 5/21. Electrical, (rear), 6 horns, 6 blower motors, multiple warranty and recalls and now my front driver seat belt. They’re refusing to fix it even though I have reported it before. They’re saying over 60,000 miles makes it no longer under warranty. I reported it before and they said that it was okay. …”
NHTSA complaint #11717820, filed 2026-02“The horn is a known issue to stop working on the Hyundai Elantra. I have had my car for 10 months, and the horn does not work. This is a very big safety concern and I have been told by mechanics and other Hyundai Elantra owners this is a constant issue.”
NHTSA complaint #11559151, filed 2023-12
Buying note. Check recall status for the rearview camera and seat-belt pretensioner campaigns before buying, and confirm whether the horn warranty extension has been used. A short test drive that exercises cruise control, the backup camera and the horn will show whether any of the most commonly reported faults are present.

Example complaints
Forward collision avoidance: “I bought my 2021 hyuandai elantra on September 7 2023 almost 2 months ago and the emergency braking system comes on pretty often while driving my vehicle on the road and freeway so the brakes will lock on me whenever the car is in drive which could cause a serious crash and probably cause damage over time to brake pads and other things this problem has occurred over 5 times within 2 months”
NHTSA complaint #11558126, filed 2023-12Electrical system: “Odometer Fraud. The contact purchased a 2021 Hyundai Elantra. The contact stated that it was discovered that there was a mileage discrepancy. The vehicle was a dealer sale. At the time of purchase, the mileage was 51,192 and at the time of receiving the vehicle from the dealer it was discovered that the mileage was 50,310.”
NHTSA complaint #11702957, filed 2025-12, 51,192 milesOther or unknown: “I have had to get the horn replaced on my ELANTRA six times the horn goes out and this can be a very big safety hazard as it has caused people to almost hit me because they didn’t see me and my horn wasn’t working to alert them this needs to be addressed as soon as possible as this could cause someone to lose their life in the wrong instance”
NHTSA complaint #11569887, filed 2024-02Seat belts: “I bought my car at McGrath Hyundai in chicago in May 2021. It’s been in their shop 30 plus times for various and repeated issues. As of late, over the last 6 months, I have reported to them and to Hyundai, my drivers side seat belt won’t retract properly and the high mounted brake light warning continuously goes off, a dinging, stating that there is an issue. Hyundai and McGrath repeatedly misdiagnosed and refused to fix these issues when they were first brought to their attention when under 60,000 miles. …”
