2022 Hyundai Elantra Problems

Federal Safety Recall Fraud and Vehicle Endangerment Report Vehicle: 2022 Hyundai Elantra Blue Hybrid | Involved Dealerships: Earnhardt Hyundai North Scottsdale & Larry H. Miller Hyundai Peoria This complaint documents severe federal safety recall fraud and mechanical endangerment by authorized manufacturer franchise dealerships. In April 2025, Earnhardt Hyundai took physical possession of my vehicle for a federally mandated Hydraulic Electronic Control Unit (HCU) braking/cruise control safety recall. Staff verbally verified the recall was complete, but the physical invoice and subsequent written email admission from Service Drive Manager [XXX] confirmed the safety repair was completely omitted with "no excuse."To resolve this braking risk, on April 22, 2026, I brought the vehicle to Larry H. Miller Hyundai Peoria to have the uncompleted HCU safety recall corrected. Subsequently, on June 17, 2026, I returned to the Peoria facility for a warranty deck lid repair and a scheduled oil change.Upon releasing the vehicle on June 17, the Peoria service department actively jeopardized my hybrid engine integrity by installing an incorrect, out-of-spec oil fluid weight (5W30) and releasing the vehicle with a completely loose, unsealed engine oil cap. This gross negligence forced me into a dangerous 140-mile high-altitude mountain highway transit ([XXX] to Flagstaff) with a compromised engine bay, creating an immediate engine fire hazard and risk of sudden highway power failure. The loose cap and incorrect fluid were independently verified and caught on video by Milestone Auto Repair in Flagstaff.The manufacturer's franchise network is falsifying federally mandated safety recall records and releasing vehicles in life-threatening, non-compliant conditions. I'm requesting an immediate NHTSA investigation on both dealerships. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

FAULTY REARVIEW CAMERA My 2022 Hyundai Elantra sedan rearview camera fails to display clear image or displays no image when shift gear is in reverse position. 2021 and 2022 Hyundai Elantra sedan models were recalled - Recall #271. I need my vehicle repaired but have been told by Hyundai Corporate that my vehicle is not eligible. That is why I am filing this complaint.

Teenage daughter was in seat belt. Laid over a little when she sat back up the seat belt tighten around her waist and would not release. When tried to pull down from top it continue to tighten and lock around abdomen. With every small move it locked up more until there was no choice but you cut the belt because it was cutting off circulation.

I own a 2022 Hyundai Elantra with only 72,000 miles my check engine light came on for the code p048900 for the Egr valve. It is no longer covered by any warranties but other year models have been recalled due to the same issue.

The horn on my vehicle all of a sudden does not work. Im afraid that i'll be in a accident because im unable to blow it. Plenty times ive almost been in a accident & it was literally nothing i could do because my horn isnt working. secondly, something is going in with the suspension on the right side of my car. Too much rattling noise. I see in the complaints im not the only one having this issue. third but not least, the ac isnt working. blowing out hot air. ive also seen where alot of people is complaining about that Ive had this car only a year and it has too many recall issues.

Description of Incident: The vehicle is experiencing significant engine oil dilution by gasoline. Upon inspection of the dipstick, the oil level is consistently found to be well above the "Full" mark, and the oil emits a strong, pungent odor of raw fuel. This indicates that unburnt gasoline is bypassing the piston rings and entering the crankcase during normal operation, particularly in colder temperatures or during hybrid engine cycling. Safety Risk: The dilution of engine oil with fuel significantly reduces the oil's viscosity and lubricating properties. This creates a high risk of premature engine wear, rod bearing failure, and sudden engine seizure or stalling while the vehicle is in motion. A sudden loss of motive power at highway speeds poses a severe crash hazard to myself and other motorists. Attempts to Correct: I have noted that similar Hyundai models using the 1.6L platform (such as the Tucson Hybrid via TSB 23-EE-002H) have received software updates to address this specific issue. However, when contacting the dealer regarding my Elantra Hybrid, I was informed that no such software fix or service campaign currently exists for the CN7 Elantra model, leaving the safety defect unaddressed. Expected Resolution: Hyundai should be required to issue a recall or technical service bulletin for the Elantra Hybrid to update the Engine Control Unit (ECU) logic, ensuring the engine reaches and maintains temperatures necessary to prevent fuel accumulation in the oil.

The contact owns a 2022 Hyundai Elantra. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated. Additionally, there was an abnormally strong gasoline odor coming from the vehicle. The vehicle was taken to an independent mechanic; however, the vehicle was not formally diagnosed. The contact was informed that there was a crack in the engine, causing a leak. The vehicle was then taken to the dealer, but it was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 23,825.

Transmission slippage, near failure, unable to accelerate safely past 20mph. Need to floor the gas peddle which causes me to go over the desired speed.

My vehicle experienced a sudden and complete brake assist failure, including the emergency brake. I was unable to stop the vehicle, which directly resulted in a collision. Prior to the crash, the car showed no warning lights. After the accident, I had the vehicle inspected at the Hyundai dealership. The dealership stated they could not reproduce the failure and “found no issues,” which contradicts the symptoms. Since the crash, I discovered two Hyundai Technical Service Bulletins that directly match the failure I experienced: TSB 23-01-036H-1 (Relates to HECU/Electronic Parking Brake failure) TSB addressing DTC C1620 (Relates to FCA Sensor/Automatic Braking malfunction) These TSBs relate to brake assist malfunction, emergency brake concerns, and similar stopping failures. The dealership did not disclose these TSBs, did not apply the corrective procedures, and cleared the car as having “no defects.” The dealership wrote “could not reproduce concern” and “no problems found,” despite the vehicle having just been in a brake-failure crash. This brake failure created a major safety risk with potential for severe injury or fatality. I am reporting this because the defect appears unresolved, the dealership denied it, and the TSBs show Hyundai is aware of brake-related issues. I request that NHTSA investigate this brake-system failure as part of a potential manufacturer safety defect. The vehicle is currently secured at the dealership (Lithia Hyundai, Las Vegas) and is available for inspection upon request by NHTSA investigators.

Intermittently while driving the vehicle will suddenly engage the traction control (TC)/electronic stability control (ESC). The light flashes for a short period (probably no more than a couple of seconds) and the car slightly jerks to the right. A loud noise is heard when this happens and the brake pedal shakes. Then the light will stop flashing and the car will begin operating normally again. Typically, the problem will reoccur shortly after it happens. I took the car to a dealer, and the dealer was unable to replicate the problem. The service manager stated that there were no codes and no history, and without a code the problem could not be diagnosed. This problem occurred multiple times over the last few months.

My car was hit from the rear by another vehicle while I was traveling with my [XXX] daughter. The impact was very strong, and one of the tires came off. None of the airbags deployed, and I feel there may have been an issue with the airbag system. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact's wife owned a 2022 Hyundai Electra. The contact stated that while driving at 68 mph and the accelerator pedal was depressed the vehicle collided with a deer. The contact stated that the air bags deployed upon impact. The vehicle was towed to a salvage lot. A police report was filed. The contact's wife sustained neck, left shoulder, and chest injuries that required medical attention. The manufacturer was not notified of the failure. The failure mileage was approximately 60,000.

The contact owns a 2022 Hyundai Elantra. The contact stated that while parking the vehicle and turning to the right or the left, there was an abnormal grinding sound coming from nearby the wheels. The contact stated that while continuing to turn the steering wheel, the sound would stop. The contact took the vehicle to the dealer however, the mechanic could not determine the cause of the failure. The vehicle was not repaired; and the failure persisted. The manufacturer was made aware of the failure. The approximate failure mileage 4,000.

Hired a local tire shop to install winter tires on a second set of wheels, with a second set of TPMS sensors. Later, I discovered the car was not picking up the sensors, but it also failed to illuminate the TPMS sensor alert. When I took it back to the tire shop, they checked the TPMS with their own sensors and said they were working fine, so they didn't know why the car didn't detect them. I called my Hyundai dealer, and they said that aftermarket TPMS often don't work, and I have to use Hyundai-approved TPMS. This is fine, but the owner's manual ought to say so. I checked the owner's manual, and it doesn't say that only Hyundai-approved TPMS can be used. The dealer replied that Hyundai doesn't like people installing aftermarket parts. I replied that installing winter tires is not usually considered an aftermarket modification, and a person shouldn't be inhibited from installing winter tires. So all I ask is that the owners manual should make this clear. In the section on TPMS, it should say that only Hyundai-approved TPMS sensors should be used, or else it should say that if the driver installs a second set of wheels with winter tires, that this installation should be done by a Hyundai dealer and not by another tire shop. Of course, the owner could install the winter tires on the factory wheels with the factory TPMS. But this would mean that every season, the all-season and winter tires would be swapped and re-mounted and re-balanced, which is unnecessary. It is standard practice to buy a second set of wheels and TPMS sensors to make seasonal tire changeover easier. Since installing winter tires on a second set of wheels is a routine practice, and not usually considered an aftermarket modification, therefore, if this car has special TPMS requirements, they should be indicated in the manual.

My Rear view camara has stop working and there is no recall available for my Elantra by vin number. Is the same problem from the 24V879000 campaign. Please inform me if there is a recall for my car because it’s causing problems in visibility for reverse parking.

EXPLODING SUN/MOONROOF

I own a 2022 Hyundai Elantra with only 72,000 miles my check engine light came on for the code p048900 for the Egr valve. It is no longer covered by any warranties but other year models have been recalled due to the same issue.

Vehicle: 2022 Hyundai N Line Mileage at Initial Incident: ~17,000 miles Components Involved: Engine and Engine Cooling; Exhaust System / Emissions; Air Bags (SRS) I am submitting this complaint to document unresolved emissions system and Supplemental Restraint System (SRS) safety concerns involving my 2022 Hyundai N Line, as well as the manufacturer’s refusal to ensure proper diagnosis and corrective action following a documented dealer service error and subsequent warranty repair. At approximately 17,000 miles, a Hyundai-authorized dealership failed to reinstall an engine oil seal during a routine oil change. This error caused rapid engine oil loss at highway speed, activation of the oil warning system, and oil discharge onto the roadway. The incident is documented in Hyundai service records and is not disputed. Sudden oil-loss events of this nature are known to cause latent or progressive damage to internal engine components and federally regulated emissions systems, even when immediate engine failure does not occur. Despite proper maintenance after this incident, the vehicle subsequently set DTC P0420 (Catalyst System Efficiency Below Threshold – Bank 1) at a mileage far below expected durability. Hyundai replaced the catalytic converter under warranty. I requested diagnostic data, inspection findings, and documentation supporting the repair, but the dealership refused to provide anything beyond a basic repair invoice. Immediately following this Hyundai-authorized warranty repair, the vehicle developed a new drivability defect, specifically hesitation during acceleration, which was not present prior to the catalytic converter replacement. This indicates a post-repair nonconformity and raises concern that emissions-related components may not have been fully repaired or that additional systems were affected during the warranty repair process. When I returned the vehicle for evaluation, the dealership stated that it would not diagnose the vehicle unless an acti

Horn does not work

I drove my vehicle to the store, parked and went in to the store to get some things. When I came out and started the car several things were wrong with the car. The power steering was not working, the RPM gauge didn't work at all, the back up camera also was not operational. The check engine light was on, the forward collision light was illuminated. I was able to drive it home but that was a sketchy drive home. The next morning I got in the car and started it up no problem, none of the issues from the previous day were there, the power steering worked perfectly and everything was fine. I still drove it to AutoZone to get it check with a scan tool, and when I did the scan tool didn't come up with any faults. This all happened about two weeks ago. Hopefully the problems don't come back. vehicle mileage is 15,000 and I've had the car for almost a year so whatever it is better be covered under warranty. I also have been having a kind of wailing sound from my brakes when I slowly reverse, It's a high pitched squeal that is usually heard when the brake pads are worn. It sounds like a deeper kind of wailing sound. It actually comes and goes and never does it in normal drive only in reverse, If anyone else has experienced this please let me know.

During the summer, I used to get some rattling on my new Elantra right after beginning to drive, after a long interval of parking under the sun. But once the car cooled down due to the A/C, the rattling would disappear. I never bothered to find the exact source of rattling because it used to last only a couple of minutes. Now in the winter, something in the passenger side starts rattling every time I go on a bump! So I took the car to the dealership following a whole week of consistent rattling. They said the noise is coming from somewhere in the dashboard and it is likely due to the misalignment caused by the shrinking of plastic in the cold. They said I could leave the car with them for 2-3 days and they could open up the dashboard and find the exact source of the noise. However, the disclaimer was that opening up the dashboard could actually introduce more rattle after it was assembled back, because the dashboard plastic parts are not precisely machined. Also, if the cause of the rattle was not found to be a manufacturer defect, I would have to pay diagnosis fee as well as the price of any broken parts that needed replacement, along with the labor charge to replace it. What's the point of warranty then?

I bought my 2022 Elantra less than a month ago, I drove the car on two round trips on the highway taking care-- that's it. One morning in Ottawa there was a cold snap and the bumper cracked on its own leaving sharp plastic edges on the front of the car. I also had paid almost $3,000 for an extended warranty but I don't know if the Surgeoner Hyundai dealer will replace the bumper yet. Coincidentally, while I was at the dealler another elantra almost exactly like mine had the same problem!

The headlights go off and on randomly It happens during the day and evening I have brought it to the dealer two times and they said after five days they cannot duplicate the problem At night time it is very dangerous when the headlights go off as I drive in a rural area I have submitted daytime photos which shows the malfunction I cannot submit nighttime photos as it is too dangerous The problem occurs daily The vehicle is available for inspection
