The embedded navigation system tends to provide directions getting the vehicle into off road areas that are not designated to be driven. This not only causes damages to the car but also leads to unsafe situations. While driving in the upper peninsula of michigan headed to the kitch-iti-kipi, it took me to tall grass and high voltage towers almost getting me to a ditch. While driving in st. Augustine beach, it almost took me to the ocean. While driving near lubbock texas around a detour due to construction, it almost took me to a cliff.
While slowing down from highway speed during hot weather, the front passenger door suddenly became unlatched and partially opened. A warning alert sounded, and I had to pull the door closed. There were no prior warnings or symptoms, and the dealer has not been able to reproduce the issue.
I was driving on the highway around 70 to 75 mph and suddenly the sunroof exploded. No debris impact. Just suddenly and randomly the glass just exploded and shattered.
Significant mechanical and drivetrain problems: ? loss of drive power and sluggish acceleration: reported as early as November 7, 2024 ("bumpy driving, grinding and clanking noise"), with issues worsening by January 2, 2025 ("slower acceleration, bumpier ride, metal clinking and cracking sounds"), and most severely on June 6, 2025 ("car shifts hard to the left then goes back and forth (wobble)," "greatly reduced" power, and "snapping" noises). You've had at least five repair attempts for these issues. ? vehicle shaking/wobbling: this has been a recurring complaint since November 18, 2024 ("car shakes when accelerating") and continued through multiple visits, including may 21-27, 2025 ("wobbly feeling"), June 6, 2025 (shifts "back and forth (wobble)"), and July 16, 2025 ("bounces excessively"). ? loose steering/difficulty turning: you've reported "difficulty turning" and "resistance when turning left," with a feeling of "less control" or "lack of control" while turning. This was noted on November 18, 2024, and persisted through April 14, 2025, and July 16, 2025. ? noises from underneath the vehicle: complaints include "grinding and clanking noise" (November 7, 2024), "loud noises" (November 18, 2024), and "metal clinking and cracking sounds" (January 2, 2025), and "snapping" noises (June 6, 2025). • electrical/infotainment system malfunctions: ? interior and exterior lights turning off while driving: on January 2, 2025, all interior and exterior lights turned off for approximately 3 seconds while driving. ? bluelink service and infotainment system disconnects/shutdowns: ongoing issues with bluelink service, including loss of connectivity and interruptions. • numerous repair attempts and days out of service: ?at least eight separate service visits for these issue.
Component or system: the brake system, specifically what appears to be a false abs activation or ieb (integrated electronic brake) system malfunction. The component is available for inspection upon request. Safety risk: while braking at speeds between 25-40 mph, typically on dry pavement and more frequently on downhill grades, the brake pedal exhibits a chugging sensation, erratic stopping behavior, and pedal softening consistent with unintended abs activation or ieb malfunction. This occurs on dry roads where abs activation is neither warranted nor expected, creating unpredictable braking response and extended stopping distances. The defect has occurred 24 documented times since [xxx], and existed prior to that date. Dealer confirmation: yes. During a ride-along at edmond Hyundai on [xxx], a technician directly witnessed and confirmed the occurrence. Despite this confirmation, it was not documented on the repair order. Two prior repair attempts returned cannot-reproduce results: March 2, 2026 at bob howard Hyundai and March 10, 2026 at edmond Hyundai. Additional repair/inspection attempts: on April 7, 2026, norman Hyundai opened and closed a repair order without the consumer's knowledge and refused to provide a copy despite an explicit request. On may 23, 2026, a scheduled appointment at bob howard Hyundai was missed; a reschedule request was subsequently ignored by the dealership. Hma case no. [xxx] is active. Warning lamps or prior symptoms: no warning lamps have illuminated. The defect presents exclusively as a physical sensation—pedal/brake chugging, softening, and erratic stopping during normal dry-pavement braking. The issue has been present since delivery on [xxx].
