I was performing a low-speed maneuver to reverse-park into my driveway. After making a right turn between my driveway and the driveway of a neighboring townhouse across the street, I came to a complete stop. When I shifted the vehicle into reverse, the vehicle did not reverse as expected and instead unexpectedly accelerated forward. I applied the brake but was unable to stop the vehicle before it traveled forward into the driveway across the street and struck the garage door of a neighboring townhouse. The maneuver was being performed at low speed. Weather conditions were clear, and the driveway surface was dry. The cause of the unexpected acceleration is unknown at this time. No warning lights, messages, or alerts were observed prior to or during the incident. Immediately following the collision, I placed the vehicle into park and applied the parking brake, at which point the vehicle came to rest. Upon impact, the driver-side front airbag deployed. Smoke and a burning odor were observed coming from the deployed airbag. The incident posed a safety risk due to the vehicle’s unexpected forward movement during a low-speed maneuver and resulted in property damage. No injuries were reported. The vehicle remains available for inspection.

The Elantra had less than 15,000 miles on it. I was driving on [XXX] at about 80MPH for about 1 hour. With no warning, while going up over a very large, high bridge/overpass (above a large outlet emptying from the everglades into the Atlantic ocean near Stuart Florida) the power totally died. A warning light came on saying the hybrid system was not functioning instructing me to pull over to the shoulder. This happened just as I crested the top of the overpass. I was able to coast to the bottom of the bridge, cross two lanes with large 18 wheeler vehicles making this challenging and park on the shoulder at the bottom of the bridge. The vehicle was towed to a nearby dealer. Their mechanic determined the "brain" between the hybrid battery and the drivers controls (the gas peddle) had failed, which disabled all power to the wheels. Had I not been cresting the top of the bridge it would have been impossible for me to move to the shoulder. This was an incredibly dangerous scenario that occurred with no warning. This failure of a key electronic component put me at extreme risk of a high speed accident on a very busy turnpike with no control whatsoever of the speed of the vehicle. There should be a redundant "brain" that would take over in this "failure" situation that would provide power at least for a limited time allowing a driver to maneuver to the shoulder. It was a miracle I was not killed. Had I been driving on limited access high speed lanes (as exist in Orlando where I live and my wife frequently drives which has no real shoulders one can safely pull over onto) the situation would have absolutely life threatening. These high speed toll lanes eliminate any ability to actually safely park and exit the car. I traded the car in (warranty covered repairs) the next day for a normal gas powered Hyundai. I will never drive a hybrid again until this type breakdown has been addressed so it can never occur. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2023 Hyundai Elantra Hybrid has has defective windshield washer nozzles 2 times so far. The factory nozzles clogged and had to be replaced. Then I got replacements installed under warranty by the local dealership. Those are now clogged exactly the same as the originals. The replacement nozzles failed much faster than the factory original equipment parts did. I am only using standard washer fluid. The fluid was tested by the dealership and is normal. Even high pressure compressed air can’t get through the nozzles at all. I am having a second replacement set ordered as of today. I suggest a recall or redesign of these defective nozzles. If you are driving just after it has rained and a passing vehicle hits a puddle and splashes dirty water all over your windshield you have no way to spray it off and clean it, so you can’t see where you are going at all. This is a major safety issue and will definitely cause an accident in such circumstances. It has been raining in my area several days per week for the past couple of months. There is lots of construction and road construction in many areas, so there is lots of dirt/mud after each rain on the roads. This creates a potentially dangerous and possibly life-ending situation if you are driving, get your windshield splashed with muddy water and can’t spray it off to clear it and can’t see where you are going suddenly, while you are on a highway. If you can’t see through the windshield you can’t even see if it is safe to pull off to the side of the road or not. These windshield nozzles need an emergency redesign and recall issued.

The horn has failed four times on my vehicle, and I have owned and maintained it since November 2022. While Hyundai has replaced it under warranty at no charge, I foresee this being a continuing issue.

This vehicle I am driving has going on 24,000 miles only and over the course of the 23,000 miles it started making me do a 12V reset which very scary when you in traffic, have to pull to the side of the road, the car blinks "Check Hybrid System" with the little what looks like a tire pressure monitor system but it is a exclamation point and says "HEV" inside. My vehicle will die while pulling off to the side of the road, I have to park it, and 12V reset it, and start the car up again, in order to get to where I was going. I can not sit in one place. In fact this battery reset happened two times last night on June 18th at a drive thru while waiting for dinner and once while waiting on a pharmacy drive thru line about two weeks ago. All this is idling. I never had a lockout issue with my car where I had to get in with my key and 12V reset it. It's only when the car is on and idling. I'm well aware of Hyundai hybrids having 2 batteries, so it is definitely not the battery controlling my acc, it's controlling my main controls. I have done so much research on my vehicle and just know this will be such a hassle to get replaced although I paid very good money for my vehicle, and the batteries are under warranty. I will have to roll the dead battery into Hyundai's lot so they do something, but even then they think 12V resetting will be a normal thing, not when I'm travelling down the freeway during rush hour. A 12V reset should be there for utmost emergencies, not to be used on a daily basis multiple times a day. Hyundai needs to take ownership and do something about it. Is it an alternator to the battery or is it their lithium ion batteries they use, is it a wire that sucks, they need to do something and get all the hybrids fix because it's not just Elantras, many Tucsons, sonatas, etc. Have the same issue all across the years I have seen to 2020. Very faulty.

During driving, vehicle displayed a system error indicating an issue with the hybrid system. The vehicle then immediately, and without warning, completely shut off and caused the driver to have to manually guide the vehicle to the side of the road without power assistance. The vehicle is available for inspection upon request, however we have taken it to the dealership who have inspected the vehicle but told us they could not find an issue, even though we clearly experienced on. The incident can easily be verified by our insurance company, who had to tow the vehicle. This incident put our safety at risk as it not only caused a sudden vehicle failure which could have further risked accident, but the driver also suffered heat stroke waiting for the tow truck. As stated earlier, the service center at the dealership could not reproduce or confirm the issue and have simply stated that the vehicle should just be driven as is. The vehicle has not been inspected by the manufacturer, police, or insurance representatives. I'd like to further note that this service station and dealership is called Horne Hyundai and is located in Apache Junction, Arizona. They have ignored this issue, gaslighted us, and left us with no option but to report them and this vehicle.

The National Highway Traffic Safety Administration (NHTSA) has identified the presence of substandard and dangerous driver’s-side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN). These inflators were not supplied, approved, or authorized by the vehicle manufacturers and have primarily been found in vehicles that previously experienced a crash and underwent airbag replacement using non-genuine parts. These dangerous inflators have ruptured during deployment, posing a serious risk of injury or death due to metal fragments entering the vehicle cabin. To date, Hyundai is aware of three people who have died while driving a Hyundai vehicle with one of these substandard replacement airbag inflators that deployed in what likely would have been a survivable crash. NHTSA has issued a public advisory urging vehicle owners and service professionals to have vehicles inspected if there is reason to believe that a non-genuine replacement airbag may have been installed. Vehicles with salvage or rebuilt titles, prior airbag deployments, or unknown repair histories may present a higher risk. NHTSA strongly cautions against self-inspection by vehicle owners and recommends inspection by trained technicians.

The National Highway Traffic Safety Administration (NHTSA) has issued an urgent safety advisory regarding dangerous, counterfeit driver‑side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN), that have been identified in U.S. vehicles following prior crashes, theft, or non‑certified airbag replacements. These inflators are not approved for use, may rupture during deployment, and have caused serious injuries and fatalities. Please see attached announcement, provided by NHTSA, for more details.

Some 2019MY and newer vehicles equipped with a front view camera may illuminate certain warning lights and trigger DTC C272246 fault code for the front camera. In the following cases, the front camera auto-calibration range may be exceeded while driving: • If the front camera is not properly installed and is completely or partially detached. • In case of excessive changes affecting the vehicle's balance (e.g., loading excessively heavy cargo in a specific location of the vehicle, or significant under-inflation of the tires). • Specific road conditions affecting the vehicle's balance (e.g., excessive road crown) This TSB provides instructions on how to service the vehicle when the front camera related warning light(s) are triggered due to system out of calibration (DTC_C272246).

Some Elantra (CN7/CN7A), Elantra N (CN7 N) and Elantra Hybrid (CN7 HEV) vehicles may experience the following conditions: • Lack of airflow coming from the forward-facing center vents • Mode actuator not changing airflow direction after various inputs • Popping/snap noise when switching between different modes If any of the conditions above exist, follow the repair procedure in this bulletin to replace the ventilator lever and cam mode guide.

This bulletin provides information regarding condensation related to the accumulated moisture in the headlamp, rear combination lamp, daytime running lamp (DRL), or fog lamp. This TSB illustrates the various causes of condensation inside the lamp assembly. Lamp assembly replacement is NOT necessary in most cases. This condition can be eliminated by turning on the lamps with the engine running for several minutes or during normal driving operation.
