2022 Hyundai Sonata Fuel System Problems

Your 2022 Hyundai Sonata had a recalled fuel tank that was serviced at a dealership. Several months after the recall repair was completed, your fuel tank ruptured and caused severe damage to the vehicle. This suggests the recall repair may not have properly resolved the underlying fuel tank defect.

Your car's check engine light came on in November 2024 for a cylinder 2 misfire and fuel mixture problem. The dealership replaced a cracked fuel injector, but the same misfire returned less than a year later in September 2025. Now your car shakes violently when you accelerate and stalls at stop lights, creating a serious safety risk. The repair will likely involve replacing the fuel injector again or diagnosing why the same cylinder keeps misfiring.

Your car's engine may suddenly lose power and fail to accelerate when you press the gas pedal. This problem has been linked to a fuel system issue that Hyundai is aware of (NHTSA Campaign 25V796000), but your dealer may not have completed the repair yet. You should contact Hyundai directly to ensure the fuel system components are inspected and replaced if necessary.

Your 2022 Sonata experienced unexpected engine revving and jerking while idling and driving at various speeds, with ABS, traction control, and warning lights turning on, plus a message saying "Front Collision Avoidance Deactivated." Your dealer replaced a valve and gasket, but couldn't complete the required recall repair because the needed part wasn't available yet. You're concerned about a potential fire risk and feel the recall is taking too long to be addressed.

Your 2022 Sonata has been stalling while driving at various speeds and failing to restart, leaving you stranded. You've had the spark plugs replaced and taken your car to the dealer multiple times, but the problem keeps getting worse. Hyundai has notified you of a recall (Campaign 25V796000) related to the fuel system, but the repair part isn't available yet — they've indicated this is likely the root cause of your stalling issue. The fix will involve installing the recalled fuel system component once it becomes available.

Your 2022 Sonata has required fuel injector replacement twice in three years. Most recently, your car became very sluggish, couldn't exceed 20 mph, smelled like gasoline, and shook slightly — requiring a tow to the dealer for another fuel injector replacement. The issue appears to be recurring with this vehicle. Fixing this will involve replacing the fuel injectors, which deliver fuel to your engine's cylinders.

After 6 hours of highway driving, your car began shaking, wouldn't accelerate normally, and emitted a burning smell. The dealership diagnosed a failed fuel injector and high-pressure fuel rail at just 4,100 miles. The fix will involve replacing both the fuel injector and high-pressure fuel rail components.

Your fuel tank has swollen or expanded, which has caused damage to the vehicle's frame. This structural damage may affect the integrity of your car and should be inspected by a professional. The repair will likely involve replacing the fuel tank and assessing/repairing any frame damage caused by the expansion.

Your check engine light came on, and the dealer found a problem with your fuel tank that they wanted to charge you $3,500 to replace. However, you discovered there's a recall covering this exact fuel tank issue on Hyundai Sonatas, which the dealer should have applied at no cost. The dealer initially refused to acknowledge the recall and suggested you file a false insurance claim, then later warned the vehicle could be dangerous to drive. You were able to have the repair done for free at another dealership under the recall. Resolving this will involve the dealer honoring the manufacturer's fuel tank recall and potentially addressing the questionable service practices.

Your car's stereo system with integrated cameras and sensors is experiencing intermittent failures. You've noticed the system sometimes malfunctions but can temporarily restore it by pressing a button beneath the volume control. The dealership wants to charge nearly $200 to diagnose this issue as part of a recall check.

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.

The contact owns a 2022 Hyundai Sonata. The contact stated while driving at an undisclosed speed, there was an abnormal sound coming from underneath the vehicle. No warning light was illuminated. The vehicle was taken to a local dealer and was repaired for a fuel valve failure. The vehicle was repaired; however, shortly after the repair the check engine warning light illuminated. The vehicle was taken back to the same local dealer where it was diagnosed with the fuel valve failure. The vehicle was repaired; however, the failure had reoccurred. The vehicle was taken back to the same local dealer where it was diagnosed with a fuel valve failure. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 92,000.

****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.
