2026 Hyundai Palisade problems

“On September 15, 2026, my 2026 Hyundai Palisade Calligraphy would not start and could not be driven. AAA responded, tested the 12-volt battery, and advised me that it had a bad battery cell. The vehicle was towed to Larry H. Miller Southwest Hyundai Albuquerque for diagnosis and repair. A service representative later told me that a parasitic electrical drain or malfunctioning component may have depleted the battery, but I have not received a written diagnosis confirming the cause. As of September 28, the vehicle remains at the dealership and has not been repaired or returned to me. I have also experienced two seat-related safety concerns. The driver’s seat moves backward automatically and presses into the second-row captain’s seat area where my child’s rear-facing car seat is installed. This movement pushes the child’s head forward. In addition, the second-row seat controls sometimes do not respond when pressed, or the seat moves in the opposite direction from the one selected. I am concerned about my child’s safety from the seat movement and about being stranded with my three children if the vehicle fails to start again. I am reporting the conditions I…”

“While driving on the expressway the driver side door opened and I had to hold it until I was able to slow down to unlock the door and close it. I have it set to lock the door when the gear is shift out of park. Screen starting flashing and beeping.”

“On XXX, while traveling southbound on [XXX], the vehicle crossed the intersection of [XXX]. Approximately 50 feet past the intersection, the vehicle experienced a sudden, complete loss of motive power and total electrical system failure without any prior warning. The entire instrument cluster and infotainment system went completely dark. All electrical controls failed immediately, including the hazard warning flashers, which could not be illuminated to warn oncoming traffic. Because the vehicle utilizes an electronic gear selector, the transmission could not be shifted into Park (P) or Neutral (N). I was forced to bring the vehicle to a stop directly in the active roadway lane and manually hold down the mechanical brake pedal to prevent rollaway. This sudden vehicle blackout and total loss of propulsion in active traffic created an immediate life-safety hazard, stranding the unlit vehicle in a live traffic lane without emergency signals. The vehicle had to be towed via tow truck to dealer.”

“My vehicle suffered a complete loss of power when trying to accelerate from a low rate of speed. This has now happened twice while driving and poses a safety risk to me and my family. The problem has not been reproduced by the dealer. The vehicle has been inspected by the manufacturer. There was no warning or symptoms before the problem occured. Warning lamps appeared after the problem.”

“On September 21, 2026, at approximately 9:20 AM, while attempting to turn off the engine of the parked vehicle, the engine failed to shut down as commanded. Due to severe ECM misfire and erratic anti-stall compensation, the engine surged uncontrollably and propelled the vehicle forward. The Forward Collision-Avoidance Assist (FCA) completely failed to detect the obstacle, alert the driver, or apply emergency braking, resulting in an unavoidable low-speed collision and slight front-end body damage. The following day, on September 22, 2026, at approximately 2:49 PM, the vehicle abruptly triggered a powertrain fail-safe mode in traffic, forcefully restricting speed to roughly 20 mph (limp-in mode), when my wife found it when trying to running faster from a STOP mode, to prevent catastrophic catalytic converter damage caused by persistent combustion misfires. It is impossible to be the wrong operation of my wife since limp-in mode cannot be activated during low speed running. On September 23, 2026, the vehicle was taken to an authorized Hyundai dealership to apply pending TSB 26-01-068H (Campaign 9D6). While the dealer completed the software update and reported no…”

“I first brought my vehicle to the Towson MD Hyundai Service Department, near my summer home, upon receiving a warning that the front sensor was not operating. I was advised that the issue will be covered under warranty. Imagine my surprise when I was advised that it would not be covered because the service team located documentation in the vehicle's file indicating that the sensor had been damaged while the new vehicle was being transported to or delivered to the Sarasota FL dealership where we purchased it. They said this documentation specifically chronicled the damage. I reported this to Hyunai's upper mgmt, was assigned a rep who promised to contact Sarasota on my behalf and work to resolve the issue between the two dealerships. After many weeks, she reported back that Sarasota denied that this damage had occurred because the notes/documentation Towson located could no longer be found in the system. But she assured me that they would continue working with the two dealerships to get to the bottom of what had occurred and she would get it covered. It took most of the summer, many calls from the assigned representative stating she was still trying to reach the…”
