2023 Hyundai Palisade Powertrain & Transmission Problems

I am reporting a recurring, life-threatening electronic failure in my 2023 Hyundai Palisade. On [XXX], while turning into an intersection, the vehicle's brakes spontaneously engaged, stalling the car in the path of oncoming traffic. During this event, multiple critical safety systems failed simultaneously, including the headlights and horn, leaving me unable to warn other drivers. A "violent" surge was required to clear the intersection, risking a high-speed collision. Similar spontaneous recurrences occurred on [XXX] and [XXX], and most recently on [XXX]. These incidents are characterized by "phantom braking," total loss of propulsion, and a complete lack of interior/exterior electronic response. Technical Evidence: Diagnostic scans revealed 16 distinct fault codes (including C161608, C181287, and U012687) involving the Chassis Control Module, Electronic Control Unit (ECU), and communication buses. Despite these logged codes, Hyundai and the dealership have repeatedly returned the vehicle to me, stating they "cannot replicate" the issue, thereby dismissing a documented electronic record of failure. Arbitration Status: I entered into BBB Auto Line Arbitration (Case #[XXX]). Hyundai has contested the claim by attempting to manipulate the "start date" of the defect to February 2024 to avoid Lemon Law statutes, despite dealer records confirming the first occurrence in August 2023. As of January 13, 2026, the dealership is again attempting to force me to take delivery of the unrepaired vehicle. This vehicle is a "phantom" safety hazard. The manufacturer’s inability to replicate a logged electronic fault during a brief test drive does not mitigate the extreme risk of sudden braking and power loss at highway speeds. I am requesting a formal investigation into these specific fault codes and the electronic integrity of this model.

In compliance with the safety recall issued for my vehicle regarding the defective seat belts, I brought my vehicle in to Vision Hyundai, Canandaigua, NY for the recall work to be completed. Upon the service department's investigation of the seat belt components, they discovered further issues with it, beyond what was initially identified under the recall. Service department advises that it will take minimum of 1 month to obtain parts and make repairs. Service department issued a compact SUV which is not capable of safely installing my child car seat, or carrying the number of passengers which my affected vehicle does, putting a strain on our family's routine needs. Additionally, the affected vehicle was brought into the shop to address a powertrain issue where the vehicle loses all power and will not accelerate over 20mph, posing a serious safety concern. Hyundai has not provided any update on this or how it will be handled.

The vehicle was brought to the dealership at around 17,000 miles with concerns regarding a clunky sound and hesitation in acceleration. The issue is extremely noticeable while turning and accelerating. No warning lights, messages or audible chimes show up when the issue occurs. Due to the vehicle hesitation on acceleration and the clunky / bouncy feeling in the steering wheel, my wife and I think there is a safety concern (e.g. being hit due to unresponsiveness of the vehicle). The problem was reproduced/confirmed by a dealer, and the rear coupling assembly was replaced. Fast forward 18,000 miles (vehicle now has ~35,000 miles) and the exact same issue is occurring again. I am schedule to take the vehicle back into the dealership for this concern, another concern with the ABS system and general maintenance.

On [XXX] the engine light went on my 2023 Hyundai palisade SUV. Immediately I drove over the Hyundai dealership to try to find out what the problem was. On my way there, the light remained on, and the car kept making movements as if it was going to turn off, I could barely make the speed increase as I was driving. I went to Healey Hyundai located at 794 Route 52 Fishkill Ny 12524 phone number 845 831 1090 . In spite, the car light on and the issues they refused to attend the car and asked me to go back Monday morning, which I did , same issued on my way there, and I arrived there with the engine light on , service advisor Rasheena M Dyer , took the car, saw the light on, took pictures and asked me to wait for the mechanic to review the car. After two hours the service advisor, said “ there’s nothing we could do, or anything could do, the car is misfiring and anything could be causing the car to misfired, the mechanic don’t see the light right now, therefore, we can’t diagnose anything, but the car is misfiring “. I replied:” my car is under 50,000 miles and under manufacturer warranty, can you give me a rental, while you fixed the engine problem, I have 5 children , how can I drive around with my kids with an engine light on and the issues is giving me”, she replied: we won’t give you a rental because we don’t know what the problem is , ( although they know and said the car motor is misfiring )unless you pay $200 dollars . They sent me away with the engine light on, and the car making sounds and movements as if is going to go off anytime . Hyundai refused to help me although the engine lights are on and my car is still under warranty. I took the car that same day to Monro auto service at 64 north plank road ,Newburgh Ny 12550, and the checked the car and confirmed that there’s nothing wrong with the oil, or filters as the dealership try to implied , is an engine-firing problem that again, Hyundai dealership refuses to fix.

When you were at a complete stop and go to make a turn, the backend makes a clunking noise it almost hesitates like it’s having a hard time going and feels like it wants to lock up. I brought it to the dealership. They told me it was my tires and I needed an alignment. I brought it to a tire shop. I got an alignment. They told me it was not my tires. They believe it to be a differential.

11/16/2024: I was at a complete stop at a stoplight waiting for it turn green so I could turn left. When the light turned green, I pressed on the accelerator and made it about half way through the intersection when I noticed that the car had stopped accelerating but could hear and see the RMPs going up. I looked down to see if I had accidentally put it into neutral, but the DRIVE light button was still lit up. Luckily, I was close to my destination and was able to roll into the parking lot without getting trapped by traffic. I turned my car off and when I came back to it, it started and everything seem normal. 12/20/24: I drove to my office to pick up packages to mail. Then I was going to run a few errands with my mother-in-law before my 10:15 am appointment for an oil change at my Hyundai dealer. As we were turning left out of my office across 2 lanes of traffic, my car did the same thing it had done in November. This time, I had traffic approaching me from both directions. My car had enough inertia to finish the turn, but it would not respond to the accelerator. Both my mother-in-law and I were trying to figure out what was going on because she could feel it and noticed the RPMs going up without any acceleration. We intentionally looked at the "drive" button to make sure neither of us had somehow knocked into neutral. The cars coming up from behind ended up passing me on the right. Eventually, maybe 15-30 seconds later, my car "kicked back into gear" and we were able to drive normally. I took the car directly to the dealer. Told them what had happened and asked for a loaner car until they had figured it out. I had the loaner car for about 5 days and the dealership said they couldn't replicate the problem. They told me to try video it if it happens again. I laughed nervously and asked which part they wanted me to video tape while driving??? It has not happened again, but seems to have happened with other Palisades.

The ABS braking problem has not been mentioned to Hyundai or any other company or organization to date as it was just recently experienced. I recently put unscreened millings on the road end of my gravel driveway. When coming to a slow stop before entering the public road I now experience the brake vibration or chattering with deminished braking responce. Fortunately, I have not experienced this while driving on a public road in 35,000 miles.

When applying the brakes at slower speeds the over-sensitive ABS violently activates causing temporary brake loss and shaking of the vehicle. This has been addressed at Hyundai dealership and symptoms were confirmed from the service advisor. I was told that this isn’t normal operation per Hyundai. Regarding another issue. The transmission will shutter combined with 3-5 second delay when up-shifting during acceleration. I was told by Hyundai dealership that is also “normal”. If this is “normal” then why has this concern just started developing. If this is normal, why hasn’t this transmission done it from day one when we purchased the car. We are not happy Hyundai’s attempt to sell us on this falsehood! These are definitely safety concerns and should be addressed.

Major safety concern with vehicle stalling, having no power, not moving mainly in Snow Mode. The first month of purchase the car stalled, had no power, would not move in Comfort Mode. My Husband was driving and I thought it was a weird fluke or something. Then it happened driving up the hill to our house several times over the past year. That was annoying enough and THEN it snowed last week, roads were snow packed and icy. I was headed to work, had car in snow mode, attempted to pull out into traffic (thankfully with a whole lot of room between me and oncoming traffic!) and the car would NOT move. It literally stalled/lagged and would not go. I was almost read ended on a highway!!! This is not ok! I took the Palisade into the Dealership to look at/test and they "could not get it to replicate the issue". I also submitted a complaint to Hyundai Corporate, and after speaking with a Case Manager several times over the phone and via email - including sending them recorded video documentation of the issues, Hyundai determined that they would do nothing about this and would not even purchase the vehicle back. They could care less that a vehicle they produced is causing major safety issues for the public. I am beyond irate! We way overpaid for this car ("high demand" at the time of purchase) - $15,000 down, and because Hyundai does not care about their product, we just traded the vehicle in to get rid of it and had to pay an additional $7,000 out of pocket. There are literally NO WORDS!!! My families safety is worth more than the money we lost out on with that awful vehicle.

Took vehicle in for routine maintenance and first I was told my engine is misfiring. They replaced injector and then told me my engine is blown. Engine is on back order for 3+ months

At approximately 645 this morning my vehicle began hesitating and jerking as I pulled away from a stoplight. Approaching cars from behind nearly impaled me as my vehicle went from 10 mph to 20mh, then quickly decelerated to 10mph without engaging the brake. I turned my hazard lights on and slowly pulled into the closest neighborhood. There, I parked the vehicle, turned off the engine, and restarted the vehicle. The vehicle’s engine sputtered upon restart, the check, engine light came on and a notification (pictured) appeared on the infotainment screen. At 7 AM I called my closest Hyundai dealership to schedule an appointment to address the notification for the check engine, the open recall and routine maintenance. The dealer stated the issue might be the transmission. The powertrain warranty does not cover rental, however they will issue partial reimbursement after rental period. Also, directed to call regarding the warranty while at dealer on Tuesday.

Just hit 5000 miles 2023 Hyundai Palisade Calligraphy. Got my first oil change a couple hundred miles ago, car has been good. FWD model. 49 degrees outside. I was driving to work and the car suddenly lost all power, i was pushing accelerator further because the car was not moving and nothing. RPMS didnt move or anything. Coasted to the side, turned it off, restarted the car and continued to work. NO CEL.Taking it to dealership Monday Jan. 22, 2024. THIS WAS SCARY.

HYUNDAI PALISADE 2023 ENGINE STALLING / WON'T ACCELERATE IN SNOW/ICY ROADS. I have now experienced this engine stalling issue several time on my Hyundai Palisade Calligraphy 2023. It has only happened in "snow mode" so far. The car basically dies, no acceleration, no matter how hard you accelerate or floor it. I called the dealership named "Great Lakes Hyundai" in Dublin, Ohio and they said they basically can't do anything since this issue is intermittent. I will be filling a complaint with NHTSA and other state and regulatory agencies. Hyundai needs to fix this issue before people start dying on the snowy/icy roads. These are expensive cars and should not be dying on the roads like this, plus this is a very dangerous situation where the car just dies and does not respond to acceleration. No warning lights of any kind display on the dashboard. You put car in "ECO Mode", it starts driving. The car never lose traction when this issue occurs. Doing some research online, seems like lots of other Hyundai palisade and kia telluride owners are experiencing this issue and Hyundai/kia are not doing anything to remedy this issue. Here are some threads/forums for reference: [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle loses power during driving and unable to accelerate further. It slows down by itself and nearly stops on the highway. This has happened at least three times and almost caused an accident. Took it to a Hyundai dealership and was told it was fixed just to experience a similar problem the next day. They gave me a rental Hyundai Santa Fe and I experienced the same issue with loss of acceleration power and vehicle slowly down despite trying to accelerate.

My wife was merging on a freeway overpass and slammed her foot into the gas peddle for a few seconds to accelerate for the merging. Her speed of travel was around 75MPH when she put her foot into it. After reaching around 82MPH she released the gas peddle for the merger. The auto's RMP shot up to around 5K and maintained the high rpm for around 5-6 sec after she released the peddle. During these few seconds the car maintained the high rate of speed and the motor was very loud. My wife pumped the gas peddle twice in rapid succession and the RPM's the wend back down and the car returned to its normal operation. Questions from above: The component was the engine: A loud revving sound and indicated by the tac hitting 5K RPM after the the gas petal was released. This was the first indecent and if repeated, we will file another report. It has not been reported to or confirmed by any dealer or independent service center. The component has not been inspected. Due to this being the first occurrence the exact competent causing the issue would be unknown. There were not warning lamps, messages or other symptoms prior or post issue.

First issue was engine misfire and loss of power while on the highway in the middle of no where. Car eventually died and was restarted. It happened twice at around 1700 miles on the odometer. Second issue is when the rear panoramic sunroof spontaneously exploded. I’m very thankful my daughter was not in the rear seat, as this happened while driving normal speeds. Sounded like gun shot. The sunroof spontaneously combusting seems to be a problem dating back to 2018 according to other reports online. Mine is a 2023.
