2022 to hyundai tuscon now with the third cylinder misfire due to faulty fuel injector. This can be inspected upon request. Upon second occurrence, requested all cylinders be replaced and advised could not do this under warranty. Second filing to NHTSA. This incident put myself and other drivers at risk. I was driving on a highway and the cylinder misfire occurred resulting in check engine light and vehicle going into limp mode and inability to drive more than 30-40 mph. The entire vehicle violently shakes and loses power with this misfire. In the previous occurrences, could not accelerate beyond 20 mph. I could have been rear ended or caused a serious accident on the highway as a result of Hyundai faulty fuel injectors and cylinder misfires. My vehicle has now been seen 3x for the same issue and replaced by dealer. There were no warning signs prior to the failure of the fuel injector resulting in cylinder misfire and loss of power and inability to accelerate. This is a very dangerous faulty component of this year make and model- it is a known issue. Still no recall. I have a "new" car that puts me in danger every 4-6 months when I lose power in my vehicle with no warning or cause except from faulty parts. This faulty part is going to cause serious injuries/accidents if it is not addressed.

1. What component or system failed or malfunctioned, and is it available for inspection upon request" The hybrid powertrain system, transmission, or engine appears to be malfunctioning. The vehicle hesitates or stalls when pressing the gas, losing power as if it doesn-??t recognize when to transition between EV and gas mode. Yes, the vehicle is available for inspection upon request. 2. How was your safety or the safety of others put at risk? The issue caused the vehicle to lose power unexpectedly, particularly while driving at highway speeds, which forced me to pull over multiple times for safety reasons. This happened on [XXX] before the [XXX] Tunnel, creating a hazardous situation in heavy traffic. If the vehicle stalled at the wrong moment-?"such as in an intersection or while merging-?"it could significantly increase the risk of a crash. 3. Has the problem been reproduced or confirmed by a dealer or independent service center" No. I have taken the vehicle to a Hyundai dealership, but no official errors or diagnostic trouble codes (DTCs) have been detected. The dealership has not confirmed the issue unless I agree to high-cost diagnostics that may not guarantee a resolution. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle has been looked at by a Hyundai dealership, but no official findings or resolutions have been provided. The issue persists, and no recall or technical service bulletin (TSB) has been mentioned to me as a possible cause. 5. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? No warning lights, error messages, or dashboard alerts appeared before or during the power loss. The issue first started occurring at approximately 35,000-?"40,000 miles and has continued to around 50,000 miles. The first time I noticed the problem was during a long-distance drive from Los Angeles to CO INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5

Hyundai has a service bulletin for their 12V battery but isn-??t notifying owners. Today my vehicle stopped working and lost all acceleration on a busy 3 lane street that is 55mph. I was able to limp it to a left turn lane where I had to research the issue and found many others had instances like mine. The battery stops working and subsequently stops the vehicle from accelerating and tells you to -??stop safely-?? with no warning or indication that you-??re about to stop moving on a road.

Within the first year of purchase, my power train system has beeb throwing codes. I took it to the dealership where they assured me nothing was wrong. My fuel injectors then gave out. The dealership replaced them and told me -??yes these things are faulty and we see it a lot-??. After replacing it, they did not seal the fuel injectors, causing gas to gush out and set my car to smoke. I was ill from inhaling gas fumes for days. They took accountability and said that the injectors were defective in the vehicles and that they would once again fix it. I am not experiencing further engine issues which they do not know how to diagnose. My car is a 2022 purchase from the lot. The engine is defective and Hyundai is negligent. They admitted they were aware of the injector issue but didn-??t do much to correct this. After corrected, they almost had my car set on fire from fuel pouring on the engine.

While on a trip my wife started out leaving the hotel as normal. After a minute of so, we lost the ability to accelerate as if the Tuscon was not responding to the gas pedal. We were lucky we were in town so we pulled into a gas station and turned off the truck. I thought it might be bad gas so we filled the tank with hi-test and turned off several features that are related to speed control (like tracking the speed limit etc.) I have noticed at the same time we lost the ISG system (Idle stop and Go). The indication in the owner's manual points to a battery function that detects the battery is fully charged. I used a voltmeter and the battery reads 12.5v and is charging at 14v. See today's recall for Hyundai vehicles, I think the problem involves a lot more vehicles. If you check the Hyundai forum, there are a lot of complaints on Tucson as well. I hope you take this into consideration when looking into this intergrated charging control issue.

The vehicle experienced a malfunction in the ignition or fuel delivery system, specifically a misfire detected in cylinder 2 (DTC P030200). This component has been documented by the manufacturer-??s vehicle service center as an issue and may be available for inspection upon request. The misfire caused reduced engine power and hesitation during acceleration, posing a safety risk, particularly while merging onto highways or attempting to pass other vehicles. The issue has been reviewed and addressed by the manufacturer dealer service center twice (presently going in for a third time); however, the problem returned each time after a few weeks, with less than approximately 5,000 additional miles driven. The vehicle has not been inspected by police, insurance representatives, or other parties. The "Check Engine" warning lamp illuminated when the failure occurred, accompanied by symptoms of rough idling and reduced performance.

Check engine light and error message popped up on screen "A possible condition with your Engine Control System has been detected. A full system check is recommended to be done when convenient. Please contact your local dealership to schedule an appointment." Roughly 46500 miles. Contacted BlueLink and they could not help because dealerships were already closed.

While driving the car the engine died, locking up both the gas and brake pedals. The car had to come to a stop on its own, my wife could not depress the gas or brake to stop the car. She was going through an intersection and narrowly avoided a major accident! The battery light came on, the check engine light and the car started to fill up with a smell of burning plastic and gas. When trying to turn the car back on after turning it off it would start with a major shake and bang then turn back off. All warning lights stayed on. Battery was fully charged still. Autobody shop found engine issues in their pre scan before sending it to Hyundai to warranty it as it only has 6,626 miles and is 2 years old. There was a warning of low battery while we were on vacation and the car was sitting for a few days. And a sluggish start when it sat for few days like the battery was low, but it wasn-??t based on the volt meter.

The check hybrid system light came on just after I tried to accelerate from a complete stop and I had no acceleration. I had the accelerator pushed to the floor and I got no response and was not able to accelerate two different times within 5 minutes of one another. I was in traffic unable to accelerate. I took it to the dealer and they were unable to find anything wrong and told me to bring it back if it happened again.

On August 1st I was on the highway at 55 mph when my 2022 Hyundai Tucson decelerated to 20 mph and would not go faster. This occurred on the highway at 5:45 pm. This placed myself and others in danger as I was on the highway in the center lane at the time of the deceleration. After turning the car in, the dealership returned the car with no repairs but stating that I engaged a button that caused a limit to the car's speed. I didn't understand but took their word. I drove it from the dealership to the store and home. The very next morning while taking my grandson to school at 5:15 am the car decelerated from 45 to 20 mph with my grandson inside the car. This placed myself and a family member in danger along with cars around me. Each time I had to drive to the dealership in unsafe conditions. They stated that I was not engaging the brake enough to charge the battery. I do not know of ANY documentation stating the number of times the brake must be engaged per drive. I have never heard of such engineering that allows a car to only go 20 mph and create a hazard for the occupants unknowingly. The dealership has stated that refuse to fix the problem but I should engage the brakes more often when I drive. The car has spent several months in their care due to continued repairs over the time that I've had it and is currently their because of the engine light being on.

I had 2 fuel injectors fail on my car within a 3 week period. The car is only 2.5 yrs old and has 48,500mi on it Both instances where when I was on a highway. I had the 1st fuel injector fail on [XXX] and then the 2nd one failed about 3 weeks later on [XXX]. When the 2nd fuel injector failed, I was barely able to drive the car to a safe place to get it towed. I spoke with a Hyundai Corp case worker and I asked why they didn't just replace the remaining 2 fuel injectors. Her response was that they don't replace them when they fail. I now have a 2 year old car that I am afraid to drive because I never know where or when It will leave me stranded.

I had my gps on and it completely stopped working sending me in circles and the voice directing completely stopped. Very dangerous it had me making U-turns at dangerous intersections. I stopped several times put address in again. This has happened several times and it is very dangerous. Also this address is a known gps address not some obscure destination ? Next twice I have pushed the start button with my foot on the brake and the car would not start. Third try it started.

Car lost power as I was entering fast traffic area. Acceleration became unresponsive and vehicle came to halt. Would not move there after. Had it occurred a few seconds later I would-??ve found myself unable to accelerate in an acceleration lane, or shortly after merging potentially causing injury to myself and others. After getting the issue diagnosed by Hyundai it is apparently a faulty fuel injectors. Researching online, this appears to be a known problem for the 2022 Hyundai Tucson with many claiming they were left stranded on highways, at intersections and during snow fall. In general this issue makes owners fearful to drive their cars. Apparently, this may be caused by a bad batch of injectors but to my knowledge Hyundai only replaces known bad injectors instead of replacing all injectors from the faulty batch. Due to this many experience multiple failures in short periods in short periods of time, increasing risk of safety incidents. My vehicle-??s failed at approximately 22k miles but others have reported failures much sooner.
