Vehicle shifted into neutral while driving myself and others were put into danger as I was on the highway with no warning.
I am reporting a safety concern involving my 2026 Hyundai Palisade limited involving repeated engine malfunction warning lights and diagnostic trouble code p001600 (camshaft/crankshaft timing correlation fault). This issue has occurred multiple times within the first 60 days of ownership and the vehicle has been taken to a Hyundai dealership twice. The dealer has not been able to determine a permanent repair and states the code is stored as a history fault without an available fix at this time. This defect is concerning because camshaft/crankshaft timing correlation faults can potentially result in engine stall, loss of power, or unexpected shutdown while driving, which could create a serious safety risk. I routinely drive long distances and transport two small children in this vehicle and no longer feel confident in the safety and reliability of this vehicle due to the unresolved engine defect. Additionally, I understand there is a recent safety recall affecting certain 2026 Hyundai Palisade vehicles, which increases my concern about the safety of this vehicle platform. I am submitting this complaint because this appears to be a potential safety defect involving engine operation that could affect safe driving conditions.
The contact owns a 2026 Hyundai Palisade. The contact stated that the vehicle turned off on several occasions after the engine auto start/stop system was engaged. The vehicle was restarted and was taken to the dealer; however, the failure could not be duplicated. Additionally, upon starting the vehicle after the vehicle was refueled at a gas station, the check engine and several other unknown warning lights were illuminated, and the vehicle failed to respond while shifted to drive(d). The vehicle was towed to the contact's business. The vehicle was then towed to the dealer; however, the vehicle was not diagnosed because there was no warning light illuminated. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was 5,463.
I have the video but I am unsure how to upload or share incident description: the vehicle is experiencing intermittent, complete engine stalls while in motion at highway speeds. The failure has occurred four times. Initial symptom: the issue first manifested as "stuttering" and erratic behavior from the advanced driver assistance systems (adas) which I thought it was. Escalation: the vehicle has since progressed to a total loss of power. During these incidents, I was forced to pull over on high-speed corridors (hwy 46 and hwy 5) to restart the vehicle. Recurring pattern: most recently, after a stall and restart, the vehicle stalled again within a few blocks. I have captured video evidence of the stall occurring immediately after the vehicle was "reset" and put back into motion. Safety concern: this is a life-threatening defect. The vehicle loses propulsion without warning in high-speed traffic. The manufacturer’s service department (Hyundai) has been unable to identify a diagnostic fault code, citing "no problem found," and has only attempted a software/values reset, which has failed to correct the physical stalling.
While driving on a California freeway at approximately 70mph, the engine check light began flashing, the vehicle experienced a sudden and severe power loss, entered reduced power mode, and began violently shaking. Engine braking occurred without brake light activation, creating an immediate rear-end collision risk from following traffic. The vehicle would not stop shaking until restarted. This occurred twice — once in January 2026 and again in March 2026, both on the freeway with passengers in the vehicle. The dealer confirmed fault codes p0303 (cylinder 3 misfire), p0306 (cylinder 6 misfire), and p0300 (random/multiple misfire) on both visits. On the first visit the dealer called the codes normal and returned the vehicle unrepaired. The second visit lasted 44 days. The dealer could not reproduce the fault during the entire 44-day period. A Hyundai field service engineer physically visited the dealership and applied a special software update to the engine control module. The closed repair order documents this as "update special software into engine control unit" with no TSB number, no software version before or after, and no gds event number. The dealer confirmed they have no access to this update and cannot verify what was changed. No proof of correction was issued for California emissions compliance. The two recalls performed on the same repair order both have proper TSB numbers and stui documentation. The ecm update has none. Concerned about emissions compliance and potential fault code suppression on a California-registered vehicle.
I have been continuously receiving check engine notifications that show the engine cylinders misfiring. This seems to only happen at highway speeds which could cause a safety hazard should the driver need to accelerate for merging/passing/etc. I have brought this issue into the dealership once so far and they said they couldn't do anything since they were unable to replicate the issue while driving it. From what I've seen online, many other owners of this vehicle are having similar problems with the same responses from their local dealerships.
After 4 days of parking in the garage due to my travel , when came back and tried to start the car it was completely dead. Couldn’t do anything so Hyundai road assistance cane and had to jumpstart the car . Since then dash cam is not working at all and also car is having wierd sound. Hybrid system is just giving me only 15gpm but the car should have around 29 -30 mpg. Car is very new bought in oct 28th 2025. And only gave 225 miles. I am worried if if the battery is working.
Rear passenger captain chairs and third row bench do not respond to occupancy when folding. I have dogs who I put in the cargo area with the third row down. My dogs are prone to move and bump buttons which has caused one or both captains chairs to move forward when loading them into the vehicle. Hyundai is aware of the problem and a temporary remedy is pending. There were no warning lights or messages prior. From a complete stop acceleration is intermittently jerky until a speed over 30mph is achieved. This is likely to do with the engine but I’m unsure if that’s the only component involved. Safety has not been at risk yet because it still accelerates but in a very jerky manner. Definitely has caused anxiety wondering if/when it will get worse. There have been no warning lights or notifications prior to this happening.
