The full stereo system with cameras and most sensors and the car is currently at the dealership as 03/09 @11:00 am and I took it to them as well so that they can repair the other pending recall I have at the moment and they stated that it was a " point to point check recall " and that they would change it whether it would need to be or not and I raised concerns about another possible recall on the car and if they could check it out which is my stereo system they tried to charge me almost $200 and " the symptoms or warnings " was that sometimes it would happen but instead of it going out completely I was able to troubleshoot it by pressing on the little button under the volume button.
I have noticed puddles under/near rear side door/tire, the smell of gas after filling up tank. And a reduced mpg lower than normal with same driving habits.
My 2022 Sonata has had to have its fuel injectors replaced two times in the 3 years I've had it. On 12/18/2025 my car started to become very slow and could not reach over 20mph, and started to smell like gasoline and shake slightly. I had to get it towed to the Hyundai dealership and there they told me that the fuel injectors need replacing. I had the same exact problem with this car before where I had to get the car towed to Hyundai and then they had to replace the fuel injector.
My 2022 Hyundai Sonata limited had a recall issued on the vehicle. I took my vehicle to a dealership and the recall issue was taken care for my fuel tank. Months after this issue was supposedly resolved, my fuel tank exploded and the car has been totaled.
I was driving the car home from massachusetts when, after 6 hours of driving, the car started to shake and would not accelerate. It was also emitting a burning smell. I exited the highway and called for a tow truck. I was told by the Hyundai dealership that, at 4,100 miles, a fuel injector and high pressure rail had failed.
Car keep cutting off and fuel injection is not right.
In November of 2024, I had a check engine light for a cylinder 2 misfire and a fuel to air mixture ratio. Had it towed to a Hyundai dealership. Got a call the next day saying it was fixed. Picked the car up and 50 miles later it popped back up. Had it towed back again. They said my fuel injector was cracked. They had to order the fuel injector directly from korea. Took 5 days to get the part and it installed. Fast forward to September 2025, cylinder 2 misfire showed up again(same cylinder the fuel injector was replaced) and now the car shakes violently when accelerating and stalled at a stop light. Massive safety concern due to risk of an accident. Car to be towed to another dealership for the same issue less than a year apart.
Fuel injector failed. The vehicle stall and accelerate poorly due to misfires. It is leaching gasoline into the oil which can result in total engine failure. Dealership verified the injector was bad. There was a warning light at one time after refueling, presumed it was my fuel cap, tightened it, and the light went away.
Car has been running great. We Ave had the car almost 3 months. My wife drove the car to church. On the way home the car engine started acting up. She pulled over and called me. I went to where she was about 1 mile from home . My son and I got the car started it would not hardly run we got it home. It was running roughly and smelled like gas making white smoke. A rollback truck picked it up the next day. Took it to the closest dealer in cape girardeau mo. It has been in the shop3 weeks found out today it will be over another week before Hyundai gets in touch with the dealer about the problem. (injectors).
The fuel tank expanded/swelled up causing frame damage to the vehicle.
First owner, sporadic acceleration problems reported from approx 6k miles. Documented with dealership. . “couldn’t reproduce” issue every time I brought it in after an occurrence. Dangerous when entering highway, as I never knew when it would fail/stall. Eventually broke down on busy interstate highway, replaced 1 fuel injector, and guilt tripped me into “needing” to have fuel injector cleaning because the others might fail as well. 27k miles was the first breakdown. 38k was the second breakdown and almost caused a serious accident when I was unable to accelerate. Replacing all 4 fuel injectors but not covering the oil change due to their faulty fuel injectors.
Fuel lines and connections / fuel tank band / fuel tank vapor vent system hoses [xxx]: my check engine light illuminated. I immediately returned to Hyundai riverdale. They advised me it could be the fuel tank and stated they needed to keep the car for 5-7 business days. May 1, 2025: I dropped off my car for inspection, having made arrangements for a personal rental car. May 7, 2025: I received a text message (no phone call) indicating the inspection was complete and was presented with a $3500 bill to replace the entire fuel tank. May 9 or 12, 2025: marilyn from Hyundai riverdale called me regarding my vehicle. She explicitly suggested I "contact your insurance company, advise them you hit something on the road, pay the deductible, and they will pay for the repairs. " she then stated, "I know you hit something after April 9th because your fuel tank is now damaged. " I denied hitting anything. During this call, she mentioned a "recall" related to fuel tanks on all Hyundai Sonatas, which I was never previously made aware of. I questioned why I was being charged if there was a recall for the exact issue I was experiencing. She claimed my car was previously checked and the fuel tank was fine, therefore the cost fell to me. May 14, 2025: merilyn called to inquire if my insurance would cover the repairs. I informed her I was picking up my vehicle as another Hyundai dealership in newnan was willing to perform the recall repairs for free. Upon arrival at riverdale, I faced resistance but demanded my car be released. I was then charged a $200 inspection fee, which I refused to pay. Marilyn then provided my keys and, upon learning I planned to drive to newnan, stated, "I wouldn't feel right letting you drive this car off the lot and something happening to you. Your vehicle at any moment can blow up due to the fuel tank. It's very dangerous to drive and suggest you get a tow truck. " April 11-may 1st I drove that vehicle w/no idea it had the potential to blow up. Information redacted pursuant to the freedom of informati.
Car is a Sonata hybrid limited equipped with a solar roof which charges the hybrid battery. Vehicle began to cut off battery power while parked, requiring the use of a factory equipped 12v override switch in March 2025 after approximately 3. 5 years of ownership. This occurred multiple times, often when the car was parked in the sun but independent of how long it had been driven prior or how long it had sat without being started. Evaluated by two Hyundai dealers; second dealer found a fault in the "solar dcdc converter" as well as the hybrid battery bulging. Battery module replaced. Unclear if this resolves the issue or it will recur again. Am speaking to Hyundai regarding battery warranty extension as vehicle had 88000 miles on it at the time of the issue starting. Online fora (e. G. , reddit, facebook) note other customers who have had similar problems with similar fixes. - [xxx] - [xxx] - [xxx] - one individual in this thread had complete power loss while driving down the highway this issue potentially risks stranding customers, and if the hybrid battery continues to bulge increases the risk of fire which could lead to property damage, personal injury, or death.

Car keeps jerking also it’s something going on with the fuel injections I’ve had to get them replaced twice. Please help.

My car has been experiencing air defects when it would randomly stop working. Last month my car air stopped working after I picked my pet up from the groomers and all together on the service road my car shut down. After being towed to Hyundai dealership I was being demanded that I ride on e and that it could’ve been my fuel injector. After realizing it was not that they claimed it was a failed fuel pump. After paying and recording my car back not even 8 hours later my car would not turn over again with no air causing me to get towed a second time. The dealership couldn’t diagnose what’s wrong with my car so they tried to throw false accusations as to my old gas can that stays in my truck that the smell of gas is the reason why they can’t properly diagnose my car. After getting my car back and driving it home, after turning it off and back in case duplicated the same problems with me. Wouldn’t turn over or produce air. Dealership refuse to comment on the paperwork if the problems they ran into but rather called me. After keeping my car a week to drive it the problem didn’t duplicate. I’ve had my car for about 3 weeks now and the air still give me problems and don’t want to come on every now and then.
Driving on the highway ih35n at 75 mph, my car's engine randomly started violently jerking and then shut off and wouldn't start back up. Had it towed to Hyundai (2022 Hyundai Sonata ~33k miles) took a few days but they repaired it under warranty saying it was bad fuel injectors and they replaced all 4. My car just dying on the highway could of caused a bad accident at that speed. Moving to present day (June 28th, 2025) car is at 56,400 miles and its starting to jerk at low speeds and is getting terrible gas mileage again. I'm taking it back in as I am still under warranty but everything points to fuel injectors again. Only warning lights I get was when the car died on the highway. Just a check engine light.
****answers to questions above**** the dealership determined the fuel injector of cylinder 2 to be malfunctioning and replaced it. My safety was put at risk because my car lost all drive power and I could not get out of other people's way. (I was only going 40 but imagine if it happened at 80 mph on an interstate) the dealership reproduced the issue and fixed it. The dealership also stated that several models of Hyundai using the same fuel injectors had come in with the same failures. (10+ cars) not all on the same cyclinder either. My vehicle has only been inspected by the dealership at this time. There were no warnings leading up to the failure. ****full story**** I was driving at about 40 mph through town and experienced total loss of drive power. The vehicle had electric, but little to no response from the gas pedal. I manged to limp the vehicle about 200 yards to a stop light. The rpms dropped to under 300 and the engine began to idle very rough. I shut the car off while at the red light to save it from any potential internal damage. When the light turned green, I almost could not get the car to start and stay running. There was a very strong gas smell at this point, which I had assumed was coming from the engine. I had to put the gas pedal to the floor to keep it running and ride the brakes through the intersection to not hit the vehicle in front of me. After getting through the intersection, I limped it into the parking lot on the other side. This is when I noticed the check engine light had come on. There was no leaking fluids under the hood or the car. I had the vehicle towed to the nearest Hyundai dealership.
Gdi fuel injectors are faulty and causing engine misfires in multiple cylinders.
Loss of drive power increases the risk of a crash. A fuel leak increases the risk of a fire. What.
Since a few weeks after buying the car new, the battery dies and self resets every few weeks on average. No error codes occur, but the car had clearly lost power while parked, indicating an issue with power management. For the last could months, car now has 26-27k miles and is 21-23 months old, it had mostly stopped resetting. It now is dead when I go out to it, even after only a couple hours of it being parked at night or during the day. I have to manually access the car and use the battery reset button. They observe no error codes. I have read other people have the failure while driving and fear and electrical issue could be a fire hazard. At the very least, it is a personal safety issue in making me take time to access my car, which could increase my risk of being attacked while trying to get into my car safely. It has occurred 5 or 6 times since August 21, most recently on October 8th and 9th.
Loss of power while accelerating. Engine overheat notification. High oil temperature.
