Over the past month, on two occasions my vehicle has emitted gasoline fumes filling my garage, and today my interior cabin smelled like gasoline. Additionally, after warming up, my vehicle experiences acceleration drop/stuttering when accelerating after idling. This happens every day. I took the car to two dealerships (San Tan Hyundai and Chapman Hyundai Scottsdale) and they weren’t able to diagnose the issue.
I left work and my car pulled back I looked at my dash I just saw all the lights on indicators telling me I may stop or not I was so scared I live 45 mins from my job and this isn’t the first incident after the second day I bought this brand new car my low oil light came on and the dip stick was dry on a brand new car the following day and from that point on my car is like a magnet and pulls to the right lane to another car this is causing me PTSD I BEGGED my husband to drive me to work in my 48 years I’ve never been afraid of a car when I let the dealership know they don’t care it’s a stupid woman well I’ve owned 2 brand new Palisades and they were amazing vehicles this one is just not working right
-On [XXX] I was drivng on a highway while using cruise control. The car suddenly applied the brakes hard. I tried 4 times to use the accelrator and each time the brakes were applied hard again. -The car behind me laid on its horn and managed to shift to another lane thereby avoiding a rear end collison. -Fortunately I was driving in an outside lane and got the car to the shoulder. -I turned the engine off and then started the car again. -There were no warning lamps or messages that I can recall. It happened quickly. -This incident came very close to causing at least vehicle damage and possibly physical harm to the occupants of my car and the car behind me. -I took my car to the dealership which is Crown Hyndai in St. Petersburg, Florida. They were unable to recreate the problem so the issue is still outstanding. -To prevent future incidents I no longer use cruise control and turn off the FCA system when I start the car.

"What component malfunctioned...?" - Electrical system (suspected) "How was safety put at risk?" - We were unaware if the dashboard instruments were reading correctly. We also couldn't lock/unlock the doors or open/close the windows. The tailgate would also not open. "Has problem been reproduced?" - Not yet - plan to have the service center inspect. "Has vehicle been inspected by the manufacturer?" - No "Were there warning messages or symptoms?" - Yes, when the issue occurred. The vehicle reported 13 warnings/alerts. Happened for the first time on 5/2/2026 GENERAL DESCRIPTION: While the vehicle is parked or idling after sitting for a period of time, the dashboard suddenly displays approximately 13 warning alerts simultaneously, including a message stating "Check Emergency Stopping function" among others. During this condition, multiple vehicle systems become inoperative, including: - Power windows - could not open/close - Door locks - could not lock/unlock - Tailgate operation - could not open (it was closed) The vehicle appears to experience a system-wide electronic failure affecting both body controls and safety systems. The condition is intermittent but has occurred multiple times. Restarting the vehicle does NOT immediately resolve the issue. After driving for a period of time, the vehicle eventually returns to normal operation. This is a safety concern because: - Critical safety systems (automatic emergency braking / driver assist features) are (potentially) disabled - Basic vehicle functions (locks/windows) are unavailable. This is a concern if the door can't be opened and one needed to exit through the window in an emergency. - The failure occurs without warning and cannot be reliably reproduced on demand This appears to be a broader electrical or communication system failure rather than a single component issue.
"TAKE A BREAK" - the feature prompts the driver to “Take a Break” with that text and a‘Coffee Cup” logo after a certain period of continuous driving. There are instances when turning it off is necessary and Hyundai has removed that option - high distracting false alarm rate. The alert, visual and auditory are intrusive, unnecessary, demonstrate a high false alarm rate leading to frustration and distraction. While designed as a safety feature, it has the opposite effect. The system inaccurately interprets the driver’s behavior as signs of fatigue with alerts popping up at an alarming rate. Perfectly normal and safe driving behaviors see the alert popping up again and again. Further there are environmental interferences - bright sunlight, reflections off glasses, bumpy roads requiring frequent corrections - system interprets these as driver inattention and cannot tell the difference between drowsy driving and navigating a poorly maintained highway. New Hyundai models do not allow the driver to disable the Take a Break alert. “You’re cruising down the highway, minding your own business, alert and focused, when your Hyundai flashes a coffee cup icon and tells you to take a break. Again - this for the third or fourth time in 20 minutes. You’re not tired, not swerving, and frankly, you’re getting annoyed”. The system is disruptive and unsafe as it disrupts the driver activating when the system detects inattentive driving, suggesting breaks even if the driver does not feel fatigued. The alert can illuminate even during short drives of less than 30 minutes. The alert can occur extremely frequently, especially during long drives, which is extremely annoying. The warning can appear shortly after starting a trip and may repeat every few minutes, which is extremely frustrating. It is far more disruptive than safe and helpful.
The vehicle has a feature that puts a message on the dashboard that reads “Consider taking a break “ that is not able to be adjusted by the consumer or the dealer. This message can come up repeatedly and has an audio portion that overrides the audio in the vehicle. Weather conditions, back roads, and unmarked lanes of traffic will trigger this message and without the ability to adjust the sensitivity or the ability to turn it off, it is a very dangerous situation. I have had it go off multiple times in a drive when there is a strong side wind and the vehicle is being pushed around and it can be very, very difficult to safely drive when this is visually and auditory messages keep coming up on the dash without any option to adjust it. On back roads or in situations where there is snow covered roads, this message can be nonstop and go off 50 times or more in a 90 mile drive. It is the worst thing about this vehicle and it’s not reasonable for the vehicle not to have the ability to adjust the feature? I’d ask that an investigation be opened to look into this and demand that Hyundai update the vehicle software to allow the settings for this message to be adjustable. When looking on the internet for this problem, there are 100s of not 1000s of people that have been searching and complaining about this message on the new Kia and Hyundai vehicles. Thank you.
I engaged the adaptive cruise control at 50 MPH. This enabled the driver attention system which I had turned off at the start of my drive. The driver attention system is unable to see my eyes through my prescription corrective lenses. This caused the Hyundai to throw multiple 'failure to control vehicle/failure to watch road' warnings over the course of a few seconds; culminating with the system trying to stop the car in heavy traffic.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
