2021 Hyundai Palisade: check engine light

Filed Oct 20, 2026 · Engine, Transmission · CA

I am the original owner of a 2021 Hyundai Palisade SEL AWD (74,225 miles) reporting repeated engine shutdowns in traffic, severe rough idling, and an unresolved safety concern. The problem began XXX. I first brought the vehicle to Hyundai on XXX and have sought service approximately four times since June. Despite technicians stating they could not reproduce the issue, the engine stalled again on XXX after I picked it up from service. The dealership also instructed me to complete a 1,000-mile oil consumption test. When I returned after 750 miles, I was told I had returned too early. The engine subsequently shut off twice on XXX. Documented incidents: XXX 1:53 PM: Engine shut off on [XXX]. XXX, 5:38 PM: Engine shut off on [XXX]. XXX, 5:08 AM: Engine shut off at [XXX] exit, [XXX] XXX 11:35 AM: Engine stalled at [XXX]/[XXX]. XXX, 12:30 PM: Engine stalled at [XXX]/[XXX]; check engine light illuminated. XXX, 10:57 AM: Near-stall with severe rough idling at Los Gatos Farmers Market. After further rough idling, the check engine light remained illuminated. On XXX the dealership service advisor personally experienced severe rough idling and an apparent near-stall while moving my vehicle, with the check engine light on. I heard her acknowledge the issue. The vehicle remains at the dealership. I provided a written incident log and opened Hyundai case #XXX. Repeated engine shutdowns at intersections and freeway exits pose a serious collision risk. I request the federal safety agency investigate this potential safety defect. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle would shut off when idling at lights or in reverse and have delayed acceleration after stops. It also would shut off when idling in park. I took it to the dealership summer-fall 2025 and they were too busy to investigate the issue because no alarms were present. The vehicle started doing the same thing and the check engine light came on March 2026. Now it has been in the shop for many weeks because of an fuel injector issue. The dealership service department says all 6 injectors need to be replace, but warranty won't cover them all. This appears to be a common issue with 2021 Hyundai Palisade vehicles and should be investigated for a safety recall.

I own a 2021 Hyundai Palisade and have experienced a complete transmission failure that I believe Hyundai had prior knowledge of and failed to address. Before my warranty expired, I contacted the dealership several times to report transmission symptoms I was experiencing. I was told that because no diagnostic code had been produced at that time, there was nothing they could do. Eventually, my check engine light came on with a P0741 code — Torque Converter Clutch Circuit Performance. When I brought the vehicle in, the dealer flushed the transmission fluid, which came out dark and contaminated with metal particles. After running the vehicle, the fluid was still dark, indicating active internal damage already in progress. The dealership has now told me I need a full transmission replacement at my own expense. I am the second owner of this vehicle with approximately 105,000 miles. I have since learned that Hyundai issued Technical Service Bulletin #20-AT-005H-1 specifically addressing the P0741 code on the 2021 Palisade, instructing dealers to replace the solenoid and valve body harness. This repair procedure was never applied to my vehicle despite my early report of symptoms. I believe this is a known defect that Hyundai has failed to escalate to a recall, leaving consumers like me with thousands of dollars in repair costs for a problem the manufacturer was already aware of. I am requesting that the federal safety agency investigate this issue and consider whether a recall is warranted for the 2021 Hyundai Palisade.

The car will start shaking, can’t exceed a certain mpg, and does not speed up. The check engine light comes on. The car is available for inspection. I drive on the freeway and slowing down, and shaking can cause accidents. This a continuous problem.

The issue began while the vehicle was under warranty and has progressed to the point where engine replacement has been recommended. Ongoing oil loss and engine malfunction created a risk of sudden engine failure or loss of power while driving, which could lead to stalling or reduced ability to safely control the vehicle. This presents a safety risk to the occupants and other motorists, especially at highway speeds. Yes. The issue was confirmed by an authorized Hyundai dealership through oil consumption monitoring, diagnostic testing, and inspection after the check engine light illuminated. Hyundai has acknowledged the problem by authorizing testing, attempting repairs, and recommending engine replacement. Yes. The vehicle has been inspected by an authorized Hyundai dealership, and the issue has been reviewed by Hyundai Motor America through warranty and goodwill claims submitted by the dealer. es. The first symptom was unexplained oil loss beginning at approximately 66,000 miles, with no visible external leak.

The engine failed due to oil consumption. The engine burns to much oil. It burns more oil than it holds during normal intervals between changes. It also did NOT give any oil lights or engine lights on the dash (not one indicator came on). When we took it in the service advisor told us the computer had indicated a problem, but that was for the technician.

While driving after owning the car for only 2 months and before the next oil change was dure the car started surging and then died when turning a corner. No check engine light or any warning or error lights triggered on the car. The car was restarted and limped home slowly about 2 min from where I'd shut off. The hood was opened and oil lipstick checked to find no oil in the vehicle. Not oil leaks anywhere, no check oil or engine light and no error codes found by dealership. The dealership confirmed no oil leak and consumption issue, oil change done and have to return in another month to jump through hoops to get engine repaired as this is a consumption issue not a leak issue. Dealership is playing games with us around this and trying to get out of repairing the car. But internal engine issue was confirmed. Vehicle returned to us unrepaired to drive for 1000 miles and return for further review even though the issue was confirmed. This is a safety risk to me, and others on the road. Hyundai of Union County is the dealership playing games in getting this repaired. ,

My vehicle is using too much oil. I was between oil changes and my car did a safety shut down while I was driving on the busy highway with my grandchildren and left me like a sitting duck. I was finally able to get it off the middle of the highway by restarting the vehicle. My engine light was lit up. I parked it for 15 minutes and then restarted it and traveled the 40miles to home. The next day I took it to our local mechanic and he ran the code and it shut down for safety due to no oil in the vehicle. He added 4 quarts for me. 96033 was the mileage showing on my sticker for when the next oil change was due. My current mileage showed 94743 showing I still had 1290 miles before my next oil change was due. I have always used Swope Hyundai in Elizabethtown, KY for my vehicle service. I called and scheduled an oil consumption test. I did what they said and they said that it was an acceptable amount of oil loss per Hyundai standards. I am still over 1000 miles away from needing my oil change and my husband has been checking my oil for me about every 1000 miles. He stated that he has put in 5 quarts of oil in my vehicle since my last oil change. If he had not done this then I would have been left in a terrible situation again out on the road endangered of being crushed by semi trucks etc. when my vehicle would have shut down again for safety reasons to protect the engine. Why am I paying over 800 per month on a vehicle that is burning oil, I cannot trust and I work out of town 80 mile round trip and mane numerous trips to town for my grandchildren's activities. I need answers to this problem with immediate solutions. I love my vehicle but I do not love this oil consumption issue. I have researched and I do see that many of this type of vehicles both Hyundai and Kia have had issues.

My 2021 Hyundai Palisade has had some issues relating to the engine recently. We take extremely good care of our cars, and are early when due for our oil changes. A couple of months ago, my husband checked my Palisade's oil before a trip. There was NO oil showing on the dip stick! I had just gotten an oil change 2000 miles before. He added 6 quarts of oil, and it was still only showing half full. We brought it up to the dealer, and they did an oil change and $900 worth of replacing things that were not covered on the extended warranty. Last month, I drove it, and the engine light went on AGAIN. We brought it in, and they said there was no oil? We told them it is not leaking anywhere, but it might be burning off or slipping somewhere else. They did an oil change (which we had to pay for even though there was no oil) and told us to come back in 1,000 miles. We went back and they said it was burning over a half quart after 1,000 miles, but Hyundai won't do anything unless it burns more than 1 quart in that time. Then, 3 days later, my engine light comes back on, and here we are again. NO oil, not even 1,500 miles, and at the dealership again A WEEK LATER! This time, they are doing a combustion chamber cleaning? I understand there are procedures that need to happen, but this does not fix that my engine is burning my oil. 3 of my coworkers have had their engines replaced due to this issue of oil consumption and where it goes. This can cause my car to die on the side of the road, immediately, and combust! My family is at risk of being in the car, and so are others who drive around me if this happens. Why is Hyundai waiting for this to happen? This is completely negligent on their end!
