VEHICLE SPEED CONTROL
As I was pulling up to a gas pump, my car suddenly accelerated. Applied the brakes to stop but it kept accelerating. My choices were to hit the car in front of me or a snow bank. I chose the snow bank. Tons of damage to my car. Don’t have that info yet, though.

UNKNOWN OR OTHER
A semi truck passed me from the opposite direction and caused a gust of wind to be generated diagonally across the car. Both of us were traveling at highway speeds. The gust of wind caused the undercarriage retainers\clips to completely fail. The undercarriage folded back on itself and was pinned on both sides against each tire beneath the car. On the left side, the tire tore part of the undercarriage off as if it had came between the tire and the pavement. I believe this has the potential to cause a loss of control given ideal circumstances. Luckily, neither tire failed and I was able to safely pull to the side of the road to zip tie the undercarriage in place. However, part of the wheel well was shredded.

ENGINE, ELECTRICAL SYSTEM
On 5 separate occasions the car has shut itself off while driving. After the first 2 times the car was taken to the dealership where they found nothing wrong and told us to replace the battery. The battery was replaced by the dealer and within the next two weeks the car shut itself off while driving 3 more times. The car will always start back up again right away. This is a very dangerous situation.

ELECTRICAL SYSTEM, ENGINE, STEERING
For about a month now the power steering was going in and out and then just the other day, the power steering went completely out, I am now having it towed to the dealership today 02/11/2025. I've also had oil consumption problems to the point where there is only 1 quart of oil left in the engine when getting the oil changed, had the combustion cleaning done and no help. Hyundai said no to a new engine, car only has 102,000 miles on it, only 10 years old and Hyundai hasn't helped a bit, said that I would have to come out of pocket but I ended up having to spend $600 on the cleaning, which is absurd.

ENGINE
Every few months my car’s engine struggles. It doesn’t start, or I have to try a few times. For whatever reason I need to get an oil change a lot more frequently than normal and I’ve been to the shop before and the shop tells me that my engine is recalled but it doesn’t say that on the website when I put my vin number in. Whenever the engine stops working again sometimes the AC doesn’t work and it almost put my dog’s life at risk once.

ENGINE
Engine suddenly shut off middle of the road while driving and will not restart. No warning lights came on prior to the engine failure. My family safety was put at risk since engine shut off middle of the road and I had to push it to the corner lane. Just imagine if I was on the middle lane on a highway when this happened. Alternator, battery was checked by a mechanic...no issue.

FUEL SYSTEM, GASOLINE
The contact owns a 2023 Hyundai Sonata. The contact stated while driving at various speeds, there was a loud sound coming from the rear end underneath the floorboard like a part slamming on the undercarriage of the vehicle. The contact stated that the fuel gauge suddenly indicated that the fuel tank was EMPTY. The vehicle was taken to the dealer who diagnosed that the gas valve and electronic control unit (ECU) had failed. The contact stated that the gas valve was replaced, and the electronic control unit (ECU) was updated. After receiving the repair, the contact noticed that while attempting to accelerate, the vehicle downshifted before shifting to the desired gear and accelerating. The failure was most persistent while driving uphill. The check engine warning light was illuminated. The vehicle was taken to another dealer, All Star Hyundai (3950 Century Ct, Pittsburg, CA 94565) who was unable to diagnose the vehicle due to not having the tool necessary to detach the fuel tank. The vehicle was then taken to another dealer, San Leandro Hyundai a Carnamic Car Center (1066 Marina Blvd, San Leandro, CA 94577) who diagnosed that the pressure valve was swollen and the entire fuel tank and pressure valve needed to be replaced. The vehicle was not repaired. Due to the inconsistency of diagnostic results, the contact decided to take the vehicle to another dealer, Fremont Hyundai (43690 Auto Mall Cir, Fremont, CA 94538) who diagnosed that the pressure valve was swollen but had not diagnosed that the fuel tank needed to be replaced due to not finding a failure with the fuel tank. The manufacturer was not made aware of the failure. The failure mileage was approximately failure mileage was 75,000.

FUEL/PROPULSION SYSTEM
Good afternoon. My issue is related to an existing recall that Hyundai Motor sent to me back during the beginning of January 2025 for a gas valve, tank inspection (replaced if necessary.) and ECU computer update. I've been to a total of 4 Hyundai Dealers and none of them have been consistent with this recall. The first Dealer is "Future Hyundai" in Concord, California. Initially, I'd took my car there for both recall and sound coming from the gas tank and my fuel level dropping. I was told by a service advisor by the name of Hayley, that it would cost a diagnostic fee to locate the issue. I didn't have the fees. But, seeing that the gas tank was part of the equation. It was free. The gas tank inspection was never done. I was told by Hayley that the fuel valve was replaced. But they mechanics only done a quick visual. I wasn't reassured that my issue was resolved. So I'd took it to a another Hyundai Dealer. This dealer told me that part of the procedure is to take off the tank and inspect it. I didn't get that far because I was told that a tool that was used is used to take off the tank was broken. A bleeder tool. Which doesn't make sense, because the tool is used for Bleeding out air from the fuel system. "Allstar Hyundai." The last two of the 4 dealers, "San Leandro Hyundai" and "Freemont Hyundai", told me that my fuel pressure hose in my gas tank and had swelled up. San Leandro dealer told me that my gas tank expanded. But the "Freemont Dealer" only mentioned the fuel hose. But never mentioned the gas tank. But decided to add it anyways. None of these dealers have been consistent regarding the recall. "Freemont Hyundai", the last of the 4, the service man told me that my tank is available. But his story changed from the time that I can get the job done 4 times. To having to have my car for two days before they can order the part. He'd order the parts, verified to me, when I was at my appointment. But now that conversation changed.

I live northern suburbs of Illinois. I was backing out of a parking spot when I couldn’t switch gears from Reverse to Drive. My car showed flashing lights and said system malfunction and service immediately. I had to put the safety brake and turn of my car. It took a couple minutes to reset and turn on my car for me to move it.

On 02/01/2022 it had 30,371 miles And finally on 3/3/23 it had 38,269 miles. This clearly shows that somewhere along the line, the odometer was changed.

The vehicle had a recall to replace the motor for bearing failure. They replaced my motor at 101,000 miles. The second motor than failed for the exact recall of bearing failure at 65,000 miles on the new motor. They told me that since I had already have done the recall and my car was now out of warranty that I would have to pay 10% of the repair bill for another motor. This second motor should have been included in that recall.

FUEL/PROPULSION SYSTEM
The vehicle has begun to vibrate/shake badly but manageable. When a code reader was connected to the vehicle both codes 7E9 and 7E8 showed up. Upon researching, information has been found that these specific vehicles have been known for recalls due to fuel hose issues. If I continue to drive this vehicle without the issues being resolved which is not my fault, I jeopardize my son and I’s lives as well as any potential future passengers.
