2026 Hyundai Palisade transmission problems

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)

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.

The 1 year old vehicle experienced a serious transmission/drivetrain malfunction that ultimately made it unable to drive. On September 3, 2026, while I was on the road, the vehicle stopped operating properly and had to be towed to the Hyundai dealership. The vehicle and affected components remain available for inspection at the dealership. The failure created a safety risk because the vehicle became unreliable and inoperable while being used on public roads. A sudden loss of propulsion or inability to move normally could have placed me and other motorists at risk, especially in active traffic. The problem was reproduced and confirmed by the Hyundai dealership. After performing work, the dealer told me the vehicle was ready for pickup on September 4. However, the same issue was still present before I even left the dealership, so I left the vehicle there again. A few days later, when I returned to retrieve personal belongings, the service advisor said the vehicle could not be driven and we had to go to the rear parking area where it was stored. The vehicle has been inspected and serviced by an authorized Hyundai dealership, and Hyundai corporate has also been contacted regarding the issue. To my knowledge, it has not been inspected by police, insurance representatives, or an independent repair facility. Prior to the complete failure, the vehicle showed symptoms of improper transmission/drivetrain operation. The revolutions would spike when gas was applied and then lurch forward when it finally caught. The problem became severe enough on September 3 that I could no longer safely continue driving and required a tow. I do not recall a specific warning lamp or dashboard message and would rely on Hyundai’s diagnostic records for any stored fault codes or warnings.

I am reporting a recurring safety issue with my 2026 Hyundai Palisade Calligraphy involving severe shaking, sputtering, loss of acceleration/power, stalling, and abnormal drivetrain behavior. The first incident occurred at just under 10,000 miles after driving for approximately one hour. While traveling at highway speeds, the vehicle began shaking severely and lost significant acceleration/power. After exiting the highway and stopping, the vehicle shut off. When restarted, it continued shaking and would not accelerate normally. No warning lights appeared. The dealership reported multiple stored fault codes, including transmission-related codes. The codes were reset and the vehicle was returned to me. The same condition later occurred again after extended driving. The vehicle shook severely and lost acceleration, again without warning lights. After being turned off for approximately five minutes and restarted, the symptoms temporarily disappeared. The vehicle has since undergone multiple repair attempts. Hyundai/dealership technicians replaced the flywheel. After that repair, the vehicle developed new shaking/stuttering during startup and shutdown. The vehicle was returned again and a motor mount was repaired/replaced. Two days after receiving the vehicle back from the latest repair, it is now exhibiting another serious drivability issue and appears to remain in first gear or otherwise fails to shift normally. I have video of the severe shaking. A dealership technician also advised me that multiple other 2026 Palisades at that dealership were experiencing similar issues and Hyundai had not determined the underlying cause. I am concerned the vehicle may unexpectedly lose propulsion, stall, or fail to accelerate in traffic or at highway speeds. Multiple repair attempts have not resolved the safety concern. The system will not allow me to upload the videos I have, but you may contact me for them.

My car is misfiring. It WILL NOT accelerate as it should. It is like bogging down unable to accelerate when it needs to. It’s struggling. Hyundai is aware of the issue and making owners drive regardless while they “wait for a fix”. It’s extremely dangerous. I’ve almost been hit several times trying to merge onto a highway because it will not accelerate. I’ve had total loss of power one time, putting me and my infant in extreme danger. This has been happening since APRIL.

I am reporting multiple recurring safety concerns with my 2026 Hyundai Palisade. Loss of acceleration: Under heavy throttle, the engine revs to approximately 5,000 RPM but the vehicle does not accelerate as expected. This has occurred repeatedly and appears more likely after the vehicle reaches normal operating temperature. During one incident on the highway, I needed to accelerate quickly to avoid surrounding traffic, but the vehicle did not respond as expected, creating a potential safety risk. An authorized Hyundai dealership inspected the vehicle and reset the transmission adaptive values, but the condition remains. Lane Keeping Assistance: The Lane Keeping Assistance system consistently positions the vehicle toward the left side of the lane instead of properly centering it. The issue has been reported to the dealer, but the condition remains unresolved. Power second-row seat: The power second-row captain’s chair can continue moving while folding, creating a hand-crush hazard if a person’s hand is in the path of the seat. It also interferes with proper third-row seat operation. This issue has been reported to the dealer and remains unresolved. These issues have been reported to Hyundai and remain unresolved after dealer inspections. The vehicle is available for inspection, and I have documentation and video evidence of the acceleration concern.
