Wind deflector came loose on highway after recall was performed. The wind deflector was originally reattached in 1996 shortly after purchase. The recall doesn't take into account that the manufacturing issue may of been previously repaired. I believe when the "recall" was performed(2020) the lack of removing the previous adhesive created a weak bond enabling the wind deflector to become detached. Attached is a copy of the recall instructions which contains no step to remove previous adhesives or check for previous repairs; only the use of alcohol to remove dust or particles. Hyundai corporate followed through on an investigation Case Number #[XXX](December 2024) finding that the recall was performed and they had no ability to investigate the proper method for subsequent repairs. Referring the issue back to local dealerships to apply their own judgement. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER
Twice within the first 26k miles i had 2 individual fuel injectors go bad. Both times my check engine light came on in the middle of driving, and then my car would no longer increase in speed and left me stranded on the road. Luckily, i was able to pull over to the side of the road. The random malfunction of the vehicle could’ve caused an accident or put my life, as well as the drivers on the road, in danger. When my vehicle arrived at the dealership, i was told that it was “because of the gas i was putting in my car”. I have never had any problems with any other vehicle when using the same gas, and have never heard of it from anyone else except from people with the same make and model as me. The dealership refused to replace the other 2 remaining fuel injectors because “they aren’t in need of repair” but acknowledged that I will just have to wait until the other 2 fuel injectors go bad and possibly be stranded in the middle of the road again. When picking up my vehicle after the seconds repair, I was told that my timing cover was leaking oil and that was repaired as well. When asked how that happened, the service center told me it was a factory malfunction. The first incident where Cylinder 2 went bad was on 12/27/2023 at 13,143 miles The second incident where Cylinder 3 went bad as well as the leaking timing cover was on 12/2/2024 at 25,890 miles

Excessively cracked dashboard. The entire dash in my 2009 Hyundai Sonata is cracked and a replacement has been denied by Hyundai USA. A cracked dashboard could cause reduced structural integrity. The dashboard is a structural component designed to help absorb and distribute some of the forces in a collision. Cracks can compromise this ability to perform this function potentially increasing the force experienced by the occupants and the and other parts of the vehicle. It can also cause increased risk of debris and shrapnel. During a collision the cracked dashboard may break apart more easily causing sharp or jagged pieces to become projectiles inside of the cabin these fragments can pose a serious injury risk to occupants. It can also result in an impaired airbag deployment. Many vehicles have airbags in the dashboard a severely cracked dashboard could obstruct or improperly deploy airbags for example the air bag may not fully deploy reducing its effectiveness and the dashboard may puncture or otherwise interfere with the airbag as it inflates creating additional safety hazards. Cracks may expose sharp edges or materials under the dashboard which could harm occupants during a collision, especially in areas where passengers may come into contact with the dashboard. A cracked dashboard could also cause a compromised electrical system dashboards house numerous electrical systems, sensors and controls cracks could indicate underlying damage to these components. In a collision these systems may fail or behave unpredictably which could further reduce safety features. Cracked dashboards present a significant risk during a collision and should be addressed by the manufacturer promptly to ensure its customer safety.

The part in question is the oil pan. An oil leak was identified at the place where I get my oil changed. The service center at the dealership informed me that there was a crack in the oil pan due to overtightening of the drain plug. I am not sure how they made that connection. The risk of this oil leak could lead to engine failure if oil levels drop below a certain level. There were no warning lights or messages from the car about the oil leak.

STEERING
My wife and I bought a new 2013 Hyundai Sonata GLS in August of 2013, which is now over eleven years ago. In late September 2024, with still fewer than 100,000 miles on the car, I noticed a snapping sensation/clunk sound in its steering column when changing the direction of steering (from left to right/right to left.) I researched this symptom and, with the confirmation of a Hyundai Dealer's Service Manager, diagnosed the problem as a failing soft coupler between the car's steering column and "Motor Driven Power Steering" motor. NHTSA is aware of the problem, and Hyundai was compelled to issue an elusively brief warranty extension. Having taken delivery of the car over 10 years ago, that warranty extension does us no good, and I'm being told that at the Hyundai Dealer, the job will cost us between four and six hundred dollars, including a complete wheel alignment they say will be made necessary by the repair. I found that a modestly skilled, able bodied, and properly equipped "shade tree mechanic" can buy an aftermarket replacement of this soft coupling for less than fifteen dollars and, with care and a little luck, can complete the repair for ostensibly less than that. (...Unless the job truly creates a need for a wheel alignment.) Since learning all of this, while I've considered whether my bad back is up to the cost-saving job, we've needed to keep driving the car. I estimate we've put another 1,600 miles on it and, especially lately, the coupler's deterioration has obviously been accelerating. My wife and I have agreed I'd best not tackle this as a DIY project so, at Great Lakes Hyundai in Streetsboro, Ohio, we have an appointment for its replacement and subsequent wheel alignment, but we worry about it lasting until then. We feel lucky to be able to afford the ESTIMATED costs, but shouldn't have to. This is a premature and DANGEROUS component failure. A recall should be issued. Hyundai should pay for all of it. ~ [XXX] , Ohio INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA),

Car leaked oil multiple times. First time they said it was a faulty drain plug then after a few months it kept leaking. Took it back to the dealership and they said the gasket around the oil pan was faulty causing the leak and needed replaced.

ENGINE, FUEL/PROPULSION SYSTEM
What component or system failed or malfunctioned, and is it available for inspection upon request? Since april 2025 i’ve been having low oil readings in my vehicle despite regular oil changes I took it into the dealer since my vehicle was still under warranty, which they stated only one part was under warranty. I had to pay $800 after this was replaced. I started having engine light come on. This engine light when I paid a diagnostic fee I learned that the cylinder three was misfiring. It was suggested that I have an oil change and get the oil level checked again within a week. This was done and it was determined that it was burning too much oil. I submitted this to the insurance and was told that this was not covered that there must be another reason why this was not working the way it should. 3 weeks ago Then I was asked to replace the spark plugs and coils. These were replaced for an additional cost of approximately $300. After replacing this, the check engine light gave the same condition of third cylinder damage.. And the oil level continue to decrease The vehicle was left with the dealer for approximately 10 days. They stated that the engine needed to be cleaned due to possible carbon buildup for about $800 then they stated that the spark plugs and coils needed to be replaced with a specific brand and not the type that Was previously used. Then my vehicle was returned to me, performing sluggishly with the check engine light returning with the same condition of third cylinder misfire. An inspection is available. How was your safety put at risk? The possibility engine failure away from hom Has the problem been reproduced or confirmed by a dealer or independent service center? Yes twice Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes frequently over the last 2 months

I along with other people on various websites have noted that the 2024 N-Line has something wrong with the speedometer. I first noticed is on the waze that is was different. It must have something to do with the internal GPS of the car. I tested it alongside another car and it is indeed off. It happens after driving the car into a place that isn't obvious on the map. I brought the car to the dealership and they weren't able to help. I know there is a slight allowance for speedometer being off, but this is way off. For example, it can show one is going 25, while really going 20. This causes me to have to look at Waze to get proper speed. This is a real issue and if search hyundai sonate N-line speedometer being off, you can find other people talking about this issue. Please really look into this as this is a major concern that falls outside the allowed difference in speedomter and actual speed

ELECTRICAL SYSTEM
In June 2024, I was driving my vehicle when I started to smell burning from under the dashboard. As I continued to drive, the smell got worse, and on my way to the dealer, my air conditioner stopped working. I took my car back to the dealer for service, and several days later, I was told that my car needed a hardness connected to several components in the engine compartment. I remember while I was dropping off my car at the dealer, one of the service advisors told me that it was good. I drove to the dealer because the car could have gone on fire. It's now six months later, and they have not fixed my car. I was told they're awaiting parts from Korea to complete the fix. My concern is that this part can cause a fire. Why did Hyundai not recall these vehicles? Hyundai knows about the problem. I was told that I'm not the only one waiting; supposedly, there are 100's more customers waiting for this part.

Literally for years I have been taking my car in to Rick Case Hyundai with the complaint of smelling gas even when the car was parked for long periods. Each time they said they fixed with different items. Gas cap, a part on the catalytic converter, etc. The problem never resolved but I noticed it only happened when the tank was more than half full. I got a video of gas dripping out underneath and took the car to Rick Case and gave them the video. My car has been there ten days because they first tried to say it was a seal on the fuel pump. This time I said that seems unlikely cause that only happens when tank is full and persists even after car is parked many hours. Now they report they found a pinhole leak in the gas tank. I will upload the video if this form allows. This does not appear to be a pinhole leak to me. I first noticed this around 2019. Unfortunately the video is MP4 and I cannot upload it.

Driving home car just shut off still had power to steer and brake but no engine. Pulled it off the main road and it leaked oil but still no engine. Already had the dealer replace the intake manifold at my expense despite hyundai knowing the plastic lever inside fails. We were lucky the snowplow was going the opposite direction as the weather was horrible as we got closer to home. I have a dead car in my yard waiting to have a dealer look at it. We could have been killed due to fault of engine.
