2020 Hyundai Palisade

Last year while traveling on vacation, my family was on the interstate crusing at approximately 70 MPH when the Hyundai Palisade suddenly started shaking and slowing down. It was shaking so bad, I ended up having to turn on my flashers because the vehicle would not accelerate up hill while pressing on the gas pedal. Thankfully, I was able to exit the highway and located a Hyundai dealership about 15 miles away in Jasper, AL. The dealership service department was very nice and indicated my engine oil was low. I could not figure out why this happened because we have always changed the oil at recommended intervals but once the dealership changed the oil, the check engine light turned off and we were able to proceed on our trip. Last night, we were traveling from [XXX] international airport back to [XXX] and the same pattern started all over again. After conducting some internet research based on the 2020 Palisade SEL, it appears this is a common issue for vehicles just under 100k miles. The reason I am reporting this is because Hyundai Corporate should do the right thing in this situation, by offering to replace the engine since I am within the 100k mile powertrain warranty period. I plan to take the vehicle to my local dealership today becuase there are two outstanding recalls, one of which is considered more serious due to a seatbelt latch. We waited over a month to schedule this service and the local dealership cancelled our appointment and didnt even offer to contact us to tell us this. The seatbelt issue is still not resolved and now we need Hyundai to perform oil consumption testing because the vehicle should not be burning this amount of oil while driving at speeds over 55MPH or over.

I am filing a formal safety complaint regarding my 2020 Hyundai Palisade due to severe and ongoing engine oil consumption that presents a safety risk, combined with an active federal airbag safety recall. For approximately one year, my vehicle has been consuming excessive engine oil. Approximately 1,500–2,000 miles after an oil change, the vehicle becomes dangerously low on oil. On January 19, 2026, at 171,650 miles, the dealership initiated Hyundai’s official oil consumption test. At intake, the engine oil level was so low that nothing was visible on the dipstick. The dealership confirmed no external oil leaks were present and began the manufacturer’s oil consumption protocol. After driving approximately 1,000 miles, I returned on February 2, 2026, at 172,657 miles. The inspection showed the engine was 2.6 quarts low. The dealership stated combustion chamber cleaning was needed; however, Hyundai denied the repair based solely on mileage and the vehicle being out of warranty. This level of oil consumption presents a serious safety concern. Driving with critically low oil can cause sudden engine failure, stalling, or loss of power while traveling at highway speeds. This could create a crash hazard without warning. Additionally, my vehicle is subject to NHTSA Recall #26V034000 (Recall #292 – Ejection Mitigation), involving potential failure of the side curtain airbags for third-row passengers to deploy properly in certain crash scenarios. The remedy is not yet available. The combination of excessive oil consumption and an unresolved federal safety recall raises significant concerns regarding the overall safety and reliability of this vehicle. I am requesting that NHTSA investigate the engine oil consumption issue in the 2020 Hyundai Palisade, as excessive oil burning may indicate a broader manufacturing defect affecting engine integrity and driver safety.

Vehicle is consuming or burning oil at a high rate. While dealer has done an oil consumption test and claimed it was "within tolerance," I have on multiple occasions had the car start to shudder at 2,000 miles since last oil change only to find the oil wasn't even on the stick anymore. The symptoms go away when adding oil, on some occasions more than 4 quarts of oil need to be added to get the oil to "full" on the dip stick. Multiple independent service centers have noted how dirty the oil is and how little is drained on oil change. No warning lights have come on at any time, even when car is making grinding noises and shuddering with no oil. This causes a safety issue as drivers reasonably expect to go at least 3,000 miles between oil changes and the engine could seize in traffic. Owners are being tacitly asked to add oil regularly to keep the engine functioning properly.

I am reporting a safety concern involving repeated engine stalling while driving my 2020 Hyundai Palisade. The vehicle has stalled a total of seven times during normal operation. Most of the incidents occurred while slowing down or stopped at intersections and traffic lights. In these situations, the engine suddenly shut off without warning. I was forced to immediately shift the vehicle into park and restart the engine to continue driving. The check engine light did illuminate in connection with this issue. These incidents create a serious safety hazard, as sudden engine shutdown in active traffic increases the risk of rear-end collision. The loss of engine power occurs unexpectedly and without sufficient warning. The vehicle has been inspected, and I was informed that the issue may involve internal engine malfunction requiring major repairs. Because this vehicle has experienced multiple unexpected stalls in traffic, I am submitting this complaint due to the significant safety risk posed by sudden engine failure during operation.

August 2025: While driving down the road and approaching a light, I slowed down to turn and make a left. As I braked, all lights on the instrument panel lit up and the car completely turned off. After several attempts to start the car again, the car started. After taking it to a shop, it was determined that the car had consumed all oil, despite being within the recommended milage range for oil change. I filed a complaint with Hyundai, who emailed me to talk to my local dealership. I responded and have yet to receive a response to my communication, as of February 20, 2026. Hyundai dealership has told me that I need to fail three oil consumption tests (I have), complete a combustion cleaning (it has recently been completed), and fail one more consumption test before they can submit to corporate for a new engine. In the meantime, I have experienced my car shaking, the smell of burning oil, my car "jolting" forward while driving at sustained speeds, and a tailpipe that is completely black with 67,800 miles currently on the car.

Engine is sucking the life out of this vehicle meaning it is consuming more than normal oil. Oil consumption, I had the testing done. and Hyundai has done nothing about fixing the issues Well I am the second owner of this vehicle and it should be laws in place for the second owners of a vehicle. The first owner was keeping up on the maintenance of the vehicle so have I. I also have white smoke coming from the tailpipe. as well as stalling and stopping. I am still making payments on this vehicle and it is not far that I have to constantly get oil changes every month or sometimes twice a month seems like it. That is a lot of spending for something that should not be. It is so many people out there going through the same issues. It is a few Facebook group pages made behind this. It's truly sad that Hyundai will not fix this problem. What are we to do? Please Help.
