2020 Hyundai Palisade Engine Problems

Excessive oil consumption - Hyundai is refusing to issue a recall even tho there was a class action lawsuit

Component: Engine / Engine and Engine Cooling Description: My 2020 Hyundai Palisade (approximately 155,856 miles) experienced a serious and dangerous engine-related failure that resulted in a vehicle fire. For approximately 8 months prior to the incident, the vehicle was consuming oil at an abnormal rate with no visible external leaks. This condition persisted without clear cause. While my [XXX] daughter was driving, the vehicle suddenly developed a new oil leak, and the engine failed without warning, leaving my daughter stranded on the roadway. Immediately following the failure, the engine compartment caught fire. There were no prior indications of an active oil leak before this sudden failure. The progression from oil consumption to catastrophic failure and fire presents a serious safety concern. This incident created a dangerous situation with risk of injury or worse, and it appears to be more than normal wear and tear. I am reporting this as a potential safety defect involving engine failure and fire risk. Mileage at time of incident: approximately 155,000 miles No prior accident or external cause contributed to the fire.

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.

The engine burns 1 quart per 1000 miles of driving

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.

The contact owns a 2020 Hyundai Palisade. The contact stated that the vehicle was consuming an excessive amount of oil. There was an oil-burning odor coming from the vehicle. There was a misfire coming from the engine before the vehicle stalled. The Auto START/STOP was activated while driving. The feature was turned off, but quickly reactivated. There were no warning lights illuminated. The vehicle was taken to the local dealer, who was unable to determine the cause of the failure. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 89,000.

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.

Dear NHTSA, I'm reporting a serious safety issue with my 2020 Hyundai Palisade (3.8L V6) involving excessive oil consumption without low-oil warning lights. Timeline: Oil changed: August 13, 2025 → Engine stalling/rough idle → Checked Oct 27, 2025: completely out of oil Oil changed again: October 27, 2025 → Same symptoms recur → January 16, 2026: completely out of oil again Usage: ~300 miles/week (1,200 miles/4 months) using full synthetic 5W-30—far below Hyundai's 7,500-10,000 mile interval. Safety Risk: No low oil warning despite total depletion x2, risking catastrophic engine failure while driving. Known Lambda II V6 issue per TSB 20-01-0001. Request: Investigation into oil consumption recall and sensor failure.

On roadtrip with family to daughter’s soccer tournament. Car started to shift funny then engine light turned on along with warning display saying something was wrong with the engine. We were only hour into driving so drove hour back home to dealership/service for Hyundai. They looked over the car and reported that we did the right thing by bringing it back and not continuing our roadtrip with it. The thermostat wasn’t working which would cause issues to engine with overheating and putting my family at risk with driving it on road trip with engine overheating.

Engine stall from excessive oil consumption. Oil and engine light not turning on prior to stall.

Vehicle started rattling at 96k miles with no check engine light. Performed diagnostics and found that the vehicle had zero oil inside. Determined that there was no sign of an oil leak and that the engine had internally consumed all of the oil. The rattling still exists and when reported to Hyundai, they sent me away and said to come back after 1k miles to see if it’s consumed 1.1 quarts and only then they will clean the engine and see if that helps and if after another 1,000 miles I still am consuming oil, they will replace the engine. They are refusing to provide a loaner vehicle throughout this process as well.

Twice the engine oil consumption was bone dry. No warning lights or oil leaks on the driveway were seen. The engine without oil was subject to destruction . We replaced the oil twice - with documentation . Oil changes were made within 6 months since we purchased the car ( documentation was given ). It is known that specific models were affected by a bad engine that was installed ! Hyundai has offered nothing but aggravation even though it is known that there is a problem with specific engines that were put into the 2020 Hyundai palisade .

Our motor has been consuming a lot of oil, we were told that Hyundai knows about the issue and that there is nothing they can do. We got sold a poor excuse of a warranty in which they never told us that the warranty would not cover oil consumption, but we have the “best” warranty they had. Our car has died GOING DOWN THE ROAD WITH MY 4 kids and WIFE! Cars had to swerve to avoid a collision, 5 times this has happened but yet they will not do anything! We will be seeking legal help!

See attached document for complaint.

engine is consuming alot of oil i have to put a quart every week and it has a smell of burning near the engine and white smoke at the back tail pipe.

This vehicle has excessive oil consumption, and the low oil light does not light up to tell you that you are low on oil. I only noticed that I was low on oil because the engine starts knocking and started to stall. I had the oil changed according to all service intervals and at one point the dealership told me my car had no oil left in it. I just had it changed, drove about 2k miles and already had to put more oil in because it didn't even show any oil on the dip stick. This is a safety hazard as well as an environmental problem with these vehicles burning this much oil. This started happening around 80-90k miles on the engine.

Engine started burning oil at 65000 miles. It has now run almost completely out of oil twice at about 4200 miles since last oil change, not even close to reaching the manufacturer recommended interval of 7500 miles between oil changes. On top of the engine consuming oil at an alarming rate, there are no warning indicator lights that turn on to let you know your oil level is critically low.

Here’s a more professional, structured version of your complaint while still clearly conveying the seriousness of the situation: ⸻ I am writing to formally express my concern regarding a 2020 Hyundai Palisade that I purchased from a dealership less than one year ago, along with an extended warranty. Since the time of purchase, the vehicle has experienced ongoing and significant oil consumption issues. In fact, it has spent a substantial amount of time in the repair shop—arguably more time than it has been in my possession. Despite these repeated service visits, the problem has not been resolved. The vehicle is currently consuming more than 1.5 quarts of oil per 1,000 miles, which is well beyond what would be considered normal. I have completed an official oil consumption test to document this issue. Notably, these problems began prior to even the first oil change after purchase, indicating that the condition likely existed at the time of sale. Despite the documented issue, both Hyundai Motor Company and the extended warranty provider have denied coverage for repairs. As a result, I am left with a vehicle that has a serious mechanical defect and a high risk of engine failure. I invested approximately 29,000 in this vehicle, and I am now facing the prospect of catastrophic engine damage due to a known issue that has been widely reported with similar vehicles. This situation is extremely concerning and has left me feeling misled and unfairly treated. I am seeking a fair resolution to this matter, including appropriate repair, replacement, or compensation, given the circumstances and the documentation supporting this claim.
