general problems of the 2023 Hyundai Sonata

Car stalls and shuts down while shifting to park or reverse and when slowing to turn or stopping. Also the media screen will black out and not work at times.

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.

Battery management system completely exhausting the 12v battery resulting in the car acting as if it has no power. When this happens, you can't unlock the door or open the trunk. On two separate occasions, I have encountered a complete loss of power in my Sonata hybrid, preventing me from unlocking the trunk or doors upon returning from extended trips. The first incident occurred after a ten-day absence last fall, and the most recent was on Saturday, March 14, 2025. During the latest incident, I returned from a seven-day trip and found my vehicle parked at orlando International airport. Upon approaching the car, I anticipated being able to unlock the trunk, load my luggage, enter the vehicle, and drive home. However, once again, the vehicle was unresponsive. Accessing the car required removing the cap from the door handle and manually inserting the key, a process that took approximately ten minutes, which was particularly inconvenient and concerning in an airport parking lot. This situation was even more challenging considering I am a [xxx] woman of smaller stature attempting to resolve this issue alone at night. I believe this poses a serious safety concern for all owners under similar circumstances. Following the incident last fall, I brought my Sonata hybrid to key Hyundai in jacksonville. I was informed that this is a known issue for which there is a recall; however, my vehicle model year is not included in the affected range. It was suggested that I would need to manage this problem independently. I believe this recurring issue represents a known vulnerability that could potentially expose Hyundai and its dealerships to liability should an owner suffer harm while addressing this malfunction.

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.

For like the fifth time while I'm driving the car just dies. I can be going 55 I can be going 70 and the dashboard lights up like a christmas tree and the car just dies. I have to pull the car over to the side and I have to turn it off and restart it again. And then about 3 days later the check engine light will go away. This seems like a software issue but Hyundai and my local dealer cannot help me I'm going to get killed in this thing. I can't take it on the highway I can barely take it down the street because it could go out on me while I'm driving and I could be in the middle lane and I could get killed. They tell me they can't replicate the issue but it's a software issue somebody needs to do something before I get killed. Every single light on the dashboard turns on and the engine just dies. This is like the fifth time this has happened. I think this car is a lemon but no one will help me.

My name is [xxx] , and I am the frustrated owner of a 2023 Hyundai Sonata sel. For context, I am a [xxx] woman who had never experienced the frightening event of a “brand new” car breaking down—until now. I am still in shock and trembling from the experience I had with my “new” 2023 Hyundai Sonata on the morning of [xxx]. At 9:30 a. M. , I was driving on [xxx] . I was driving the speed limit (55 mph) and cruising along when, all of a sudden, as I went to accelerate, my vehicle instead began decelerating rapidly. I pressed the gas pedal, thinking I might have let up too much or accidentally had my foot on the brake. However, pressing the gas only caused the rpm to spike, with no change in my speed. I had to act quickly, paying close attention to the surrounding traffic as my car slowed down. Thankfully, I managed to maneuver from the far-left lane to the shoulder of the highway. My speed had dropped to around 30 mph and was decreasing. Trying to safely navigate a slowing vehicle on a highway filled with traffic is an adrenaline rush I wouldn’t wish on anyone. I was in a state of severe panic. As I steered the car onto the shoulder, I noticed it was shaking and struggling to move forward. White smoke was also coming from the exhaust. Once safely stopped, I put the car in park and turned off the engine to let it cool down. After a few minutes, I restarted it and noticed the engine, oil, and battery indicators were all illuminated on the dashboard. My first thought was a battery issue, but the car was still able to turn on. However, the engine did not start. A notification appeared, stating the car was not in a condition to be driven. After receiving the car back from the Hyundai dealer I was notified that the issue was due to fuel injectors failing. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I was driving on the interstate at interstate speeds and the car started to lose power. I was able to steer the car to a safe location and call roadside assistance. It appears that the engine control system had a failure in one of the control modules. The problem was reproduced at the time that I dropped the car off with the service center. The history of the issues for the vehicle are available. My safety was put at risk because the car lost power at high speed and I was only able to limp to a safe location. No warning lights happened until the issue was already taking place. After being notified by my Hyundai app, I was able to discover that the vehicle had a history of having this code (I have only owned the car for 32 days).

2023 Hyundai Sonata limited, 1. 6 t. Battery discharged within 10 days while parked. This problem is well known to dealership. The dealership has to jump start cars and start them frequently on the dealership lot. It is impossible to park this model car at an airport or parking lot for more than a couple of days and maintain a battery charge. No warning or alerts. The problem is that the reserve amp hours of the standard stock battery is not adequate to supply the electronic drain of computers while parked.

I have had three occasions where the dashboard lights would flash and the car would lose all power. The first occasion occurred on December 29th at around 12:20 pm at a crowded intersection. The dashboard lights lit up and all of a sudden the car had no power at all. I managed to get it through the intersection and pull it off to the side of the road. To start it up I have to turn off the car by putting it in park and start it up again. This is stressful and terrifying to think about if this had happened on the freeway. Additionally, I took the car to get serviced and was charged a $1,800 bill to fix it in January. This repair took two weeks to complete. The car has since turned off two additional times on February 15th going down a hill at 40 mph and March 26th on a mountain road going 60 mph. I am very concerned this will happen on the highway and I will get into a serious accident or worse. To make matters more difficult, I have taken the car back to the Hyundai dealer again to have it looked at in April and will most likely be without the car for at least another week. I bought the car brand new and the check engine light has gone off four times since then.

1. All safety features related to the back up camera, eps, traction control, lane assist, active cruise control, automatic high beam, forward collision avoidance and more. 2. Loss of all safety features and then sudden restoration of eps would cause swerve into oncoming lanes or into neighboring lanes and/or ditches. 3. Yes the problem has been reproduced, repeatedly in cold weather and while the dealership has had it in for repairs. 4. No, but the dealership has contacted the manufacturer for repair advice. 5. Yes, every time. I have photos of my dash with the indicating lights on. 10/2/23.

When I approach an intersection to stop my car auto shut off engages. When trying to hit the gas to release my car from auto shut off the emergency auto shut off engages and I must put my car in park. Turn the ignition to off and then crank my car back all the way on. Release the park and drive. This happens intermittently for several weeks and I’ve almost been rear ended several times. I have taken the car to a Hyundai dealership for the issue and they tell me nothing is wrong.

Water continues to gush out of the driver side passenger door when opened after raining. I also found out on Friday, July 30, 2023, that water has been leaking into the trunk of my brand-new car since purchasing it on may 10, 2023. It's a hybrid. Robert ross, pearson Hyundai's new car sales manager (who I bought my car from), and I are extremely concerned about water leaking into the trunk of an electric vehicle which puts me, my family and anyone else who rides in the car at potential risk. Currently my car is at pearson Hyundai again to fix this issue for the fourth time. Attached are the three previous service invoices that I've received. If needed, I can provide three videos that I recorded of the same issue on may 30th, June 17th and July 1st. Please know that I have also shared the videos with melissa best, pearson Hyundai's service manager and jason richardson, pearson's service advisor. On July 3, 2023, I filed a report with Hyundai customer service. The case number is 21666377. The last text I received from ms. Best, pearson's service manager, yesterday (7/5/23) follows: "I’m sorry I don’t have any answers yet, we’re trying to figure this out, I’m even reaching out to somebody I know when the collision industry that understands body framing-- sent from gmail mobile".
