2026 Hyundai Palisade

There is significant delay when I step on the brakes and then there’s delay when I switch to press the gas pedal delaying the moving of the car. This happens often in local roads when at a stop and moving forward. I brought to the dealer to check and they said it’s how the car is but have no fix on it. Many times when I expect the car to move after pressing the gas pedal, there’s a delay of few seconds then the car starts to move. This concerns me a lot as it’s a safety issue.

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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Our 2026 Hyundai Palisade has experienced repeated dangerous electrical failures while driving. XXX All instrument displays went completely black while driving. The engine continued running. Gateway Hyundai in Fargo, ND, checked the vehicle but verbally reported finding no diagnostic codes. XXX While driving on the highway at night, the interior displays and exterior lights repeatedly flickered off and on. XXX The vehicle unexpectedly lost power and shut down at highway speed, requiring a tow to Don Bessette Hyundai in [XXX]. The dealership documented 36 stored diagnostic trouble codes, primarily communication faults. The codes were cleared, and an ECM software update was performed. No confirmed cause was identified. XXX The instrument panel went completely black twice while driving, lasting approximately 10 minutes and 14 minutes. XXX While driving at night, the interior and exterior lights again flickered off and on. Approximately 30 minutes later, the instrument panel went black and the exterior lights dimmed. We pulled over, activated the hazard lights, and restarted the vehicle, but normal lighting did not return. We drove approximately 14 miles with hazard lights on to reach the nearest town. The lights eventually returned, but the instrument panel continued flickering, the front camera repeatedly reported being disabled, and driver-attention warnings appeared during the drive home. These failures continued after dealership service and a software update. We are concerned about another sudden loss of engine power, headlights, or critical driver information at highway speeds. These failures pose a serious safety risk to occupants and other motorists. We request that NHTSA investigate these electrical failures.

Korum Hyundai documented my 2026 Palisade Calligraphy as having a “Failing bumper support structure” and noted a rear-bumper indentation on 3 of 4 vehicles inspected. Purchased 1/28/26, delivered 3/1/26. After road trips and the first wash following the 30-day ceramic-coating cure, the indentation was clearly evident. Multiple inspections found no evidence of impact or camera-recorded damage. The bumper was replaced through insurance and recoated. After another 30-day cure, the same indentation was again evident after the next wash and now appears better or worse depending on driving, weather and temperature. Korum referred me to Hyundai Motor America. After nearly 3 months of calls, emails and delays with no repair or resolution, Hyundai is now sending me back to Korum on 11/5. I am going in circles while the documented “Failing bumper support structure” remains unresolved with Hyundai of America/Korum Hyundai.

FACT: Complete failure by selling dealer Jeff Wyler Hyundai Colerain to perform manufacturer-mandated Pre-Delivery Inspection (PDI) under R.C. 4517.53 prior to delivery on July 20, 2026. Consequently, high-voltage hybrid computer updates, safety modules, Hybrid Control Unit (HCU), Battery Management System (BMS), and AWD actuators were never verified for road readiness. Dealer also failed to lower tires from 47 PSI shipping pressure to 36 PSI operating pressure. Operating this vehicle with unconfigured hybrid modules and tires over-inflated to 47 PSI (found around 8/12) caused severe, structural drivetrain vibrations during the first 1,100 miles (9/3). RoadForce balancer identified one bad tire (9/10) which was replaced. However, we suspect the remaining 3 tires are compromised with internal belt micro-tears as balancers cannot replicate highway speed/heat. Vibration remained after tire replacement. Further diagnostics found the propeller shaft assy was bad so it was replaced (9/21). Vibration is still unresolved; technicians are currently on track to inspect the AWD coupler. FACT: When confronted, selling dealer’s General Counsel formally denied liability (9/29), pointing to a service record executed by our local facility two months post-sale (at 1,570 miles) as satisfying their PDI requirement. Selling dealer then telephoned our local service manager (9/30) asking why they had not "claimed" the PDI with corporate. This inquiry proves selling dealer was entirely ignorant of manufacturer protocols requiring a PDI to be executed and claimed within 300 miles or prior to sale. SUSPECTED DOCUMENT MANIPULATION: On state Form BMV 4740, dealer checked "Gas/Diesel" instead of "Hybrid." We believe this was done to evade the R.C. 4503.10(C) hybrid fee and bypass Hybrid safety flags. Dealer had us initial the box, violating Ohio CSPA R.C. 1345.01 and exposing us to an R.C. 2913.42 records tampering fallout.

these vehicles are having disabling electrical issues, mine has been in the shop for 3 weeks and the Dealership along with Tech support from Hyundai are unable to repair yet. As I searched online forums I have found that every one of the 2026 palisade are having electrical issues that they cannot find a repair for and lot of these vehicles have been in the shop for over a month.

Incident

Sep 28, 2026

Certain Palisade (LX3) vehicles may exhibit delayed initial acceleration, a lack of power when accelerating, or inappropriate shift timing due to inadequate drivability logic software. Technical Service Bulletin (TSB) 26-01-086H provides instructions to perform a Transmission Control Unit (TCU) software update to correct these conditions.

Certain Palisade (LX3) vehicles may exhibit acceleration response and shift quality under certain driving scenarios that may not meet driver expectations. This bulletin provides instructions to update the Transmission Control Unit (TCU) software to refine overall vehicle drivability.

This bulletin provides information related to the navigation and head unit software changes introduced in the 2026 2nd Navigation Map and Software Update. The changes may vary depending on vehicle type, model, and navigation system. Refer to the 2026 2nd Navigation Map and Software Update Key Improvements and Additional Improvements tables in this TSB for a list of specific changes. The software can be downloaded via Navigation Updater (NAU) and updated by USB.

Some Hyundai vehicles may be equipped with a parking distance warning (PDW) sensor(s) that may trigger various DTCs and display warning messages on the instrument cluster, resulting in the PDW sensor(s) failing to detect nearby objects or triggering multiple false alarms. This condition may be a result of external damage to the PDW sensor membrane or sensor cover from rock chips or road debris, a collision, or previous vehicle repairs or modifications.

Certain vehicles equipped with internal combustion engines may exhibit higher-than-expected engine oil consumption. This bulletin provides the inspection and repair procedures for vehicles exhibiting this condition. All internal combustion engines consume engine oil as part of normal engine operation. Oil consumption rates may vary based on mileage, operating conditions, driving habits, and maintenance history. Hyundai recommends following the prescribed maintenance schedule and periodically checking the engine oil level using the dipstick to maintain proper engine oil level.
