2026 Hyundai Palisade

The contact owns a 2026 Hyundai Palisade. The contact stated that on five occasions, while stopped at a light with the Auto START/STOP system activated, the vehicle inadvertently turned off and shifted into park(P) independently. The contact stated that there was an unknown warning light illuminated. The contact attempted to restart the vehicle, and the brake pedal was firm; several attempts were needed to restart the vehicle. The contact stated that on one occasion, while stopped, the Auto START/STOP system failed to activate and the vehicle failed to accelerate as intended; however, the engine was revving unexpectedly. There was a loud clunking sound, and the vehicle jerked and then accelerated as needed. The vehicle was taken to two dealers during the failures; however, the dealer was unable to determine the cause of the failure. The vehicle remained with the second dealer. The manufacturer was notified of the failure. The failure mileage was approximately 1,500.

We are currently on a road trip. Fortunately we were in a 55mph zone and not going faster. While driving on the highway, the hood released from the latch and popped open. Fortunately the secondary latch caught it and we were able to pull over safely. I can’t imagine if we were going faster if the secondary latch would’ve withheld it. Very scary incident

It appears there is an ongoing issue with the Driver's Assistance. More specifically with automatic braking regarding forward collision. On 4 separate occasions, the vehicle has gone haywire with several alarms and icons going off at once and then sudden braking in the middle of the road before I have even realized what is going on. The issue is the car decided it was time to slam on the brakes right in the middle of the road while I was driving so it was very jarring. I have brought the vehicle to the dealership once and they kept it for 2 days to inspect the problem and could "not reproduce the problem". So they returned the vehicle to me. However, the issue occurred 3 more times after they returned it to me within 3 wks. So, I am dropping it off again for them to keep until they locate the problem now that I believe I have narrowed it down to the Driver's Assistance and forward collision issue. When I disable the driver's assistance/forward collision toggle, there "appears" to solve the issue. I have not had the same problem when that specific toggle is off as of yet. There have been no inspections from a manufacturer rep, police or insurance rep. There were a ton of warning lamps at one time just prior to the automatic braking, some regarding power train, battery, and several others. I have photos.

Safety-Critical Shifter System Malfunction - I am experiencing a recurring and serious shift system defect with my 2026 Hyundai Palisade Calligraphy. The issue first occurred within the first 500 miles of ownership, shortly after purchasing the vehicle new. At that time, the vehicle required diagnosis and repair by the dealership and remained out of service for nearly one month. Despite that repair, the same or a very similar issue has now returned. The vehicle displays a "Shifter System Malfunction – Service Immediately" warning and does not allow me to change gears while the vehicle is running. The gear selector becomes unresponsive, and the only way to restore functionality is to shut the vehicle off and restart it. After restarting, the vehicle often engages with a loud thud/clunk and significant vibration that can be felt throughout the vehicle. This creates serious concerns about the safety, reliability, and overall integrity of the drivetrain and shift-by-wire system.

I was a making a left hand turn at a stoplight. The light turned yellow, and as I was in the intersection, I pressed the gas pedal to complete the turn. The pedal went to the floor, but the car did not accelerate. It barely rolled forward. I had to slam on the brake so I would not roll into the intersection, and turn. I reeased the pedal, and tried again, and the vehicle did accelerate. This failure has happened 4 times to me. I have also had the experience with making a right-hand turn from a stop. Again, when depressing the accelerator, the engine did not go. In one case it was delayed, then sped up very quickly. I has been to the dealer twice, once for 2 days, and once for 9 days. They have been unable to find anything wrong. I was able to demonstrate the problem with a technician in the vehicle, but he really could not see me depressing the gas, so was really unable to experience that I had a problem, even though I verbally mentioned the incident. The car at the time had less than 500 miles on it. To summarize. I have experienced left-hand turn problems 4 times, and right hand problems twice., or a total of 6 times.

I am submitting this regarding the remedy implemented under NHTSA Recall 26V-160 (Hyundai Palisade, second/third-row power seat obstruction detection defect). I support the intent of this recall — the underlying defect was serious and the software update appropriately targets improved occupant/object detection. However, I'm concerned about the adequacy and scope of the remedy as applied to the Limited trim specifically. As implemented, the remedy removes the ability to control power-folding seats via the vehicle's infotainment touchscreen entirely, converts seat-fold buttons to press-and-hold operation, and requires the liftgate to be open during folding. On the Limited trim, the third row is the only row equipped with power-folding seats (the second row has no electric folding). As a result, this remedy has eliminated the entire infotainment-based remote-fold control pathway for Limited owners, with no equivalent functionality remaining anywhere in the vehicle. My concern is whether the remedy, by removing an entire control pathway rather than improving its safety through better sensor/detection logic alone, goes beyond what is necessary to address the defect, and whether this scope of functionality removal was adequately disclosed to owners as part of the recall notice. I'd like this recorded as feedback on the remedy's scope and impact on equipped functionality for the Limited trim, separate from the original safety defect itself.

We lease a 2026 Palisade with only 4k miles. Several weeks ago I was going through a toll plaza, car would not accelerate after slowing down, as if it was in neutral. All of a sudden it kicked into gear and car lunged forward. 10 min later at a traffic light car failed to accelerate after a complete stop. Press the accelerator sluggish response, then kicked back into gear. Very Scary. I pulled over and notified the dealer. Then set an appoint. Dealer did a diagnostic, found no issues, could not replicate problem on test drive . Everything was fine a few weeks. My son took the car. Had the same exact issue with vehicle not accelerating. Then kicked into gear really hard and vibrating. This was scary for him because he was in a parking lot. Luckily there was no accident as a result. However, this time an error code (check engine light) came on and the Hyundai app showed a DTC CODE- P001600 (powertrain / engine). Car was immediately taken to dealer on May 28th 2026. It is now Jun 11th. Still no time frame for fix. The THINK it a software issue and Hyundai is still "working" on a solution.

2026 Hyundai Palisade SEL 8P AWD. Brake pedal sinks to floor when depressed while vehicle is in motion, causing vehicle to glide before stopping. Defect first noticed June 1, 2026 and confirmed June 2, 2026 at approximately 530 miles during a 34-mile round trip with consistent repeated occurrence at both low and moderate speeds. Vehicle returned to dealership for diagnosis. Dealership declared unable to duplicate. No diagnostic trouble codes found. Hyundai engineering was consulted by dealership. This is a second serious defect on this vehicle — a full transmission assembly replacement was performed under warranty in May 2026 within 4 days of delivery and approximately 259 miles of personal use. Hyundai Motor America lemon law re-evaluation currently in progress.
