ENGINE, ELECTRICAL SYSTEM, VEHICLE SPEED CONTROL
2023 Hyundai Elantra SEL. Car has been slow to start this week. When I depress the brake pedal and push to start, it will start then shut off in the middle of starting then I have to try again or it will sputter then fully start but every safety alert and electrical alarm will go off in my car and nothing clears it until I drive for about 5 minutes then they all clear. I went to AutoZone and they said my battery was normal health. When this slow start happens I also notice that my vehicle doesn’t accelerate as well and it feels like it’s trying too hard to the point it will jerk forward even when I’m only lightly pressing the accelerator. I noticed this, 2 winters ago (2024) as well and I thought it was due to the very cold weather we had. Brought it to my sister’s fiancée and he couldn’t find any DTC’s but agreed something felt off. The problem stopped and now it’s the middle of summer 2 years later and doing the same thing, to the point where I’m trying to merge onto I-95 and my car isn’t accelerating fast enough and I almost got rear ended!! It only happens at speeds under 50 and is extremely unsafe to have a vehicle where you don’t know if it will just turn off while you’re driving, stop accelerating or decide to not start that morning!!!

SERVICE BRAKES
The contact owns a 2023 Hyundai Elantra. The contact stated that while driving at an undisclosed speed, several unknown warning lights flashed on and off on the instrument panel, and the brakes independently activated due to slippery weather conditions. The vehicle was taken to a dealer to be diagnosed; however, the cause of the failure was not determined. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 16,900.

UNKNOWN OR OTHER
I own a 2022 Hyundai Elantra N Line. The HVAC system began malfunctioning when the center/forward-facing dashboard vents stopped producing airflow, while the side vents continued to work. Changing the HVAC mode does not properly redirect airflow to the center vents as intended. The vehicle was inspected and diagnosed, and I was informed that the ventilator lever/mode mechanism is broken or not functioning properly. This appears consistent with a known issue described in Hyundai Technical Service Bulletin 25-HA-001H/26-HA-001H concerning the ventilator lever and loss of airflow from the forward-facing center vents. This failure affects my ability to properly control where air is directed inside the vehicle, including directing airflow toward the windshield for defrosting/defogging. This could potentially reduce visibility in conditions where windshield defrosting is necessary and therefore create a safety concern. The problem has been confirmed through a vehicle diagnostic inspection. The vehicle/component is available for inspection upon request. I have also found other Hyundai Elantra owners reporting similar loss of center-vent airflow and HVAC mode-control problems. The issue occurred without a collision or other known event that would have caused the component to fail. The repair is also unusually labor-intensive because the failed ventilator lever is located behind the dashboard and requires extensive disassembly just to access the component. I was informed that the repair would require at least 14 hours of labor, resulting in an extremely high repair cost for what is essentially a small mechanical component. The amount of labor required to reach and replace the lever makes the repair disproportionately expensive. Additionally, I have encountered multiple other Hyundai Elantra owners reporting the same or very similar symptoms, including loss of airflow from the center/forward-facing vents while the side vents continue to function. Suggests occurring issues.

ENGINE
The engine mounts on this vehicle failed. Dealership and many others online have stated that this seems to be a reoccurring issue with the 2021-2023 generation of Hyundai elantras. The vibrations of these failed motor mounts become so severe that they can dislodge the brakes making it very unsafe to drive. Hyundai should be doing a recall for this to avoid safety issues for their customers

UNKNOWN OR OTHER
The vehicle is a 2023 Hyundai Elantra N Line purchased from CarMax in February 2026 with approximately 40,000 miles. It currently has approximately 49,000 miles. The vehicle intermittently cuts off, hesitates to accelerate, and jerks/shudders during acceleration. The specific failed component or system is UNKNOWN because CarMax has not yet provided a definitive diagnosis. The suspected problem involves the engine, fuel/ignition system, transmission, electronic throttle, or another powertrain/control component, but this has not been confirmed. The vehicle’s sudden loss of power and hesitation during acceleration creates a safety risk because the vehicle may fail to accelerate when needed, including when entering traffic, changing lanes, or attempting to avoid a hazard. The unexpected cutting off of the vehicle also creates a risk of being stranded or struck by other vehicles. The problem has been reported to CarMax, but to my knowledge it has NOT been definitively diagnosed or confirmed by a dealer or independent repair facility. CarMax has required a diagnosis before proceeding with further assistance, resulting in delays in addressing the defect. I contacted Hyundai regarding the vehicle and was informed that the vehicle’s original sale/in-service date was October 6, 2023, and that Hyundai has no recorded service history at a Hyundai dealership since that date. Hyundai has not yet physically inspected the vehicle for this complaint. The specific warning lamps or diagnostic messages associated with the failure are UNKNOWN. The primary symptoms are the vehicle cutting off, hesitation when accelerating, and jerking/shuddering during acceleration. These symptoms have continued and remain unresolved. The vehicle is available for inspection upon request. I am requesting that the vehicle be professionally inspected and that the underlying cause of the loss of power, hesitation, and jerking be identified and documented.

WHEELS
To Whom It May Concern: I am submitting this formal complaint to request review of a potentially serious vehicle-safety failure involving a rental automobile provided to me by Hertz at its [XXX] location. Although Hertz is presently attempting to collect approximately $97 from me for alleged tire damage, the monetary dispute is secondary to the substantially more important issue: Hertz released a vehicle to me with an objectively abnormal tire-pressure reading, was expressly notified of that condition before I left the rental facility, advised me to disregard it, and subsequently documented a nail in that same tire. The chronology is straightforward and concerning. On XXX, I rented a vehicle from Hertz at [XXX]. At the time of checkout, the dashboard tire-pressure monitoring display showed that the passenger-side rear tire was approximately three pounds below the expected pressure. Although the reading had not yet reached a critical or red-warning level, it was clearly abnormal. The vehicle was also dirty and did not appear to have been carefully prepared between rentals, which further raised concern regarding the adequacy of the vehicle's pre-rental inspection. Before driving the vehicle from the Hertz facility, I specifically informed the Hertz employee handling the checkout that the right rear tire was displaying low pressure. The Hertz employee told me, in substance, not to worry about it. I relied upon that representation and drove the vehicle. Over the course of the rental, the pressure in that same tire continued to decline by several additional pounds. When I returned the automobile on XXX, I again specifically advised Hertz personnel that the tire was losing pressure and should be inspected. I also documented the issue in my written customer review, specifically expressing concern that providing a rental automobile with an apparent tire problem was inappropriate INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, LANE DEPARTURE: ASSIST
While driving on [XXX] north near exit [XXX] in rain, at 70 mph Adaptive Cruise Control and Lane Keeping Assistance were on. The vehicle displayed a warning that the smart systems were disabled. The vehicle then began jerking and changing lanes and speed unexpectedly. The steering wheel pulled/jerked forcefully to the left and right and I had difficulty maintaining control of the vehicle. When I attempted to brake, the brake pedal became very hard and could not press down the vehicle did not slow normally. I was able to get the vehicle onto the shoulder and shut it off. After restarting the vehicle, the problem occurred again. The vehicle was towed to Wallace Hyundai dealership in Stewart Florida and is currently being diagnosed. The cause has not yet been determined. Scared me to death. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

UNKNOWN OR OTHER, ELECTRICAL SYSTEM
The horn is intermittenly failing and was verified by a Weimer Hyundai in Morgantown, WV on XXX. This is a known defect in 2023 Hyundai Elantras and they have issued an extended warranty to address the problem. An absence of a horn is a safety issue as you cannot signal other drivers in emergency situations. It is unlawful to have a horn that does not operate in most states including WV ([XXX]) which is where I currently reside. While a horn is not required by NHTSA , if it is present it must be operable by driver (Safety Standard No. 101, 49 CFR '571.101). For these reasons I am requesting that this should have and should be considered a SAFETY RECALL which is NOT predicated on mileage. By issuing an extended warranty that stops at 120,000 miles Hyundai does not serve those with higher mileage vehicles. It is not fair for a driver to have to pay out of pocket for a KNOWN DEFECT that should have absolutely been addressed as a SAFETY RECALL. Hyundai has been contacted and I was given a case #42976455 and a case manager named Edward. Weimer was incontact with either him or Hyundai directly and they offered to split the cost of $600.00 intead of taking full responsibility. I have no full time job and cannot pay anything (nor should I have to) for a safety issue. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ELECTRICAL SYSTEM, ENGINE, POWER TRAIN
The control panel /radio panel has had a glitch or blacked out screen where it wouldn't come back on for a few hours and I could smell electrical or plastic burning after it did come back on after that the radio started changing channel on its own while screen glitched on and of with saturated static wrench on my dash comes on periodically. The tires pressure unit never has the same amount of air in it according to the gauge. Even though I have made it so that they were all equal several different times. The car feels like it misfires when that it's 9500° outside and you go for any sort of extended drive past 10-15, mi. When the air conditioner is on high, the fuel economy doesn't seem to match the way it's supposed to and some of the programming is missing since the last time it was serviced out of the control panel. Some options that we're supposed to have been there aren't there anymore and I'm pretty sure that when I use the remote to roll down my windows they're all supposed to roll down. Well only one of them does and it doesn't roll it back up the way it's supposed to when that it is foggy out. My camera system says that I'm about to get into a crash and starts blinking at me and beeping and flashing saying that I'm about to crash because my forward safety system or my rear safety system is not working properly. And yes I've let them know about these things My car has less than 25,000 mi on it and the problem started probably 3 months after I got it. When I first got it there was a bunch of little pits in the glass or I want to say hairline bubbles. I don't know what else to call them but they replaced my windshield. They didn't replace the back window that still has them

SEAT BELTS
The rear driver‑side seat belt in my 2025 Hyundai Elantra will not extend or retract. The seat belt was used under normal conditions, with no excessive force, misuse, or accident that would cause damage. It suddenly stopped functioning and is now completely inoperable. A non‑functioning seat belt is a serious safety hazard because passengers cannot be properly restrained. I brought the vehicle to the dealership, but they refused to repair or replace the seat belt under warranty. They claimed the belt was “overextended,” despite the fact that it was only used normally and has never been involved in any incident that would cause such damage. The dealer’s refusal to address a critical safety component leaves the vehicle unsafe for passengers. I am reporting this issue because seat belt failure should not occur under normal use, and the manufacturer/dealer is declining to correct the defect.

POWER TRAIN, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
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)
