2023 Hyundai Sonata

Filled gas tank up on Friday [XXX] about 10am as leaving Boca Raton, FL to head North to New Port Richey, FL. About 30 minutes later the gas mileage said there was only 90 miles left in the tank. Stopped at the next gas station to make sure nothing was leaking, added a little more until it clicked, basically full again. Got to approximately [XXX] near Morris Bridge in Tampa area, the car started to decelerate and then all the engine lights came on and car was shutting off, was able to pull to the left side of the road and Looked into the back seat noticed the back seat was rising. Looked under the back of the car and the frame looked like it was pushing up into the backend of the car. DOT was called out to the scene as it appeared the car could have exploded. This could have killed my [XXX] daughter (which was who was driving the car) or other people on the road. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was driving my 2023 Hyundai Sonata with 22,000 miles on I-96 near Grand Rapids Michigan at or slightly below the speed limit of 70 MPH. Suddenly, with no advance warning of any kind, the engine shut down. I was able to coast and maneuver to the right shoulder of the road while avoiding traffic, including a large tractor trailer that almost hit us. The vehicle than had just enough power to get off the next exit and on a local side street. At that point the vehicle would not restart and you could smell a strong odor of fuel. I called Hyundai and they sent a tow truck to take it to the nearest dealer. (I am 700 miles from home). The dealer's service department diagnosed the problem then replaced the fuel injectors still under warranty.

The fuel injectors failed again, leaving me stranded on a busy road. The first time this happened, I had a little over 8,000 miles on my vehicle - 5 months after purchase. That was two years ago. Now, the injectors have failed for the second time and I am having to pay just north of $1,000 to get them replaced at my Hyundai dealership. It was a terrifying thing to experience and my safety was at risk due to my vehicle decelerating on a busy street. I had to call the police to help shield my vehicle from other drivers. The problem has been confirmed by a dealer upon inspection and diagnosis, and the police officer that was at the scene also could see that my vehicle would not start. This dealer works at the company that manufactures Hyundais. Prior to the fuel injection failure, there were brief moments where the 'check engine' light would illuminate but it would never stay on long. Directly before my vehicle shut off on the road due to the failure, there were no light/lamps/or other symptoms noticeable.

Took my car in February 10 for a recall that pop up on the app and today is June 22 and I’m getting all the run around and different dates for my car to be ready but everything it’s time to pick up my vehicle something comes up and they told me they took my car back to the body shop for the recall issue. All the information are added on the file

My car stalled while driving through an intersection and nearly caused a T-Bone collision. The car would not start afterwards and towed to dealership. The car currently has 32000k miles on it. The inspection report stated leaking fuel injectors causing misfires. This was covered by warranty. The parts are currently backordered with no eta on possible repair indicating it might be a widespread issue. There were no warnings or lights prior to incident. The car had just been serviced at 30k miles by the dealership with no indication of possible failure given to me by maintenance department. The dealership is out of loan vehicles and I’ve been without a vehicle for 6 days now causing work and personal issues.

I have had this car checked out 3 times and on my way to the 4th appointment. I can be in the middle of the road or pulled up in my driveway the RPMs go crazy shuts off every light comes on then clicks and I have to waite and try to restart. This car has been a problem since we bought it brand new even the chrome has come loose on it. Took to 1 dealership they said it's not throwing a code so nothing they can do I pulled out of the dealership onto the busy highway and the rims went crazy lights came on and it died called the mechanic that said nothing was wrong he came out got it running took it back came back said nothing showing up so there was nothing he could do. I'm driving another 3 hours away hoping I make it to another dealership that said they would look at it after I sent pictures and a video to the mechanic. I will NEVER buy another hyundai again and definitely tell anyone I know not to.

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 was driving into work on a major road (about 45 mph) when my 2023 Hyundai Sonata stopped accelerating and my engine gave out. Initially I thought I was accidentally pressing on my break pedal but when I realized I wasn’t pressing the break, I had just enough time to turn on my hazards and get out of traffic and onto the shoulder of the road. I was stuck between a main exit and the major road. My battery, oil, and engine lights came on (no service lights had been on prior to this incident) and my car was just very slowly rolling before it automatically engaged my parking break - which makes me fearful of what would have happened if I had still been in busy traffic. I could gotten very badly rear-ended. My car only has just over 5600 miles and I never had any issues with it before and kept up with the general maintenance. I attempted to restart my car to no avail and about 30 minutes later I was able to restart my car but there was a very strong vapor smell in the cabin of my car. I got my car towed to a dealership and was informed one of my fuel injectors was misfiring/gone bad - similar to many other incidents on this site. I asked the dealership if they were able to view the state of my other fuel injectors and was told they were unable to do that, so I am unsure if other fuel injectors will go bad in the future.

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
