On January 21, 2024, I was driving the Palisade about 80 miles away from home when I got Engine Overheated message multiple times. The temperature gage would go up and to max then goes down multiple times. Finally it was discovered that the coolant was leaking. The vehicle had about 31,000 miles. It was supposedly inspected when after 30,000 on December 28, 2023. The car was towed to a nearby dealer. Since it was Sunday, I had to rent a car and went home. next day I called the dealer and was told the car would not be checked for another month at least. I was told to find other dealer in the area that can handle the inspection and fix if I wanted the car any sooner. I complained vehemently. I gave up and called other dealers in the area. Finally the same dealer called back and said that they have looked at the car it turned out there is technical bulletin for the issue. I was told to come down and get a loaner. I traveled to that location next day and picked up a loaner as my car is the only car we have. I talked to the dealer where the car was inspected last December and was told that service departments do not loo at TBS unless the owner raises an issue. I do not have access to TBS to check what's out there. This issue should not happen to consumers. Bulletins and recalls should be available publicly to all consumers to be aware of issues. I'm not sure where to go get TBS for my car. I found Hyundai's site for recalls. Nothing else. This should be addressed at the national level. Attached is a file that contains pictures of the coolant reservoir, at the beginning, after adding more coolant, then at end when it became clear coolant level is coming down.

The vehicle went into limp mode while traveling on the highway. Vehicle decelerated from 65mph to 30mph very quickly & without warning (no indicator lights came on). I was almost rear ended, since the car behind be had no idea I was decelerating due to no brake lights. It then slowly decelerated to 14mph as I was able to get off highway. Upon inspection, by me, the vehicle was found to have very little oil & I do get my oil changes on the required interval at the dealership. It had been about 2500miles since my last oil change. This vehicle is available for inspection if needed. No warning lights or messages came on & the app that notifies of problems stated the car had no issues. The vehicle has been to the dealership multiple times & I have been made to come back every 1K miles for oil consumption tests x 3. As of the 3rd test, it has been calculated that my car is burning 1qt or oil every 775miles. The dealership is requesting a new engine for my vehicle. Hopefully it will be approved. But, I personally feel this is a major safety hazard to just have your car stop at of nowhere with no warning light or alarm.

My car randomly starts itself if I leave the keys in it. Tge auto lights stopped working one night while driving. Hasn't done it again since. While my son and I were driving it decided to shut off at 50 mph. There was no warning at all. It has not been inspected as it has nit happened again to be seen.

I was on the highway when all the bells and whistles went off saying low coolant. I have under 15,000 miles and my radiator went. It was repaired under warranty but still feel this should not have happened.

Radiator began to leak in January 2023 at approximately 15000 miles. Replaced under warranty.

My Palisade 2022 was only on 10k miles when the coolant tank is completely empty. I can see coolant on the engine bay floor as well as my garage floor. There is definitely a leak which drained the coolant. This is an urgent situation since my engine could stop working on the road anytime. Checking the Palisade forum, there are numerous incident like this so this is a systematic design failure on the cooling system.

I pulled off the highway onto an exit. Midway down the exit, the engine shut off and breaking was impaired. I was able to yank the wheel to the right and pull it off onto the shoulder to avoid a collision. Was able to restart vehicle and get home

The engie restarted itself after being shut off and no key was near vehicle and continued to run overnight, filing car with carbon monoxide. Hyundai service department was contacted and said no inspection was need but to monitor car and contact Hyundai customer line and advise. The reference case number is 20244323.

Started to notice an oil spot under the vehicle at around 4500 miles. Since the car is brand new and hadn't even had its first oil change, we immediately scheduled a service appointment. We were finally able to get it into the dealership 2 weeks later and received a diagnosis shortly after drop off. Turns out the oil leak was coming from the head gasket on the right bank of the engine and requires replacement of both head gaskets. The engine oil level was low and the service technician recommended the car not be driven until it could be repaired as simply adding oil would continue to contribute to the leak. Parts have been ordered and requested via next day delivery however they currently do not have an ETA as to when the parts will arrive. The repair job is estimated at 10-12 hours so it will be out of service for 2 days just for repairs once parts do come in. Plus Hyundai would not reimburse car rental fees even though the dealer was out of service loaners however after a day, they were able to provide one. Of greater concern however is why would the head gaskets be leaking oil while the car is still basically being broken in from new. I've had cars of multiple brands with well over 100K miles that never leaked from the head gaskets. If these engines are assembly line built, I'm concerned that the torque specs were off when assembling the heads to the block causing the leak. If that's the case, this issue could begin to pop up on many other vehicles built at the same time. Hyundai is covering under warranty at no cost but now I'm concerned over our investment that we've only had now for 3 months and future reliability. The vehicle is currently out of service for an undetermined amount of time. If not caught, this could have resulted in a full engine failure as the low oil warning never came on.
