2020 Hyundai Palisade

The wind deflector for the sunroof malfunctioned while attempting to close the sunroof. The wind deflector became lodged in the track for the sunroof and broke which caused the sunroof to shift and not close fully. When researched online, this is a common occurrence with this year and model vehicle. It could potentially cause the glass to shatter above the drivers head and cause an accident. The sunroof would not fully close causing it to leak when it rained. The glass panel was removed and manually slid into the closed position to prevent further damage. Now the sunroof is inoperable. The vehicle can be inspected upon request. The issue has not been reproduced or confirmed by a dealer or independent service center. The vehicle has not been inspected by the manufacturer or anyone else. There were no warning lamps or messages prior to the failure. we would like this issue to be resolved as it is a potential hazard.

Dear NHTSA, I am writing to report a safety concern regarding my 2020 Hyundai Palisade. Recently, when I attempted to operate the sunroof, it only opened partially and made a crackling sound. Upon closer inspection, I noticed that some of the internal plastic components were breaking apart, and now the sunroof does not close properly. After researching this issue online, I discovered that numerous other owners are experiencing the exact same problem. For reference, here are a couple of user-reported discussions highlighting similar experiences: [XXX] [XXX] Additionally, I came across a Technical Service Bulletin (TSB) related to this very issue, which can be found here: [XXX] However, when I checked my vehicle’s VIN, it did not appear to be included in the list of affected models, despite my vehicle exhibiting the same symptoms described in the bulletin. This leads me to believe that the scope of affected VINs may not have been fully identified. Given the number of similar complaints shared by other Hyundai Palisade owners, it appears this may be a more widespread issue than initially recognized. I respectfully request that NHTSA consider investigating this matter further, as it may help protect and support additional Hyundai customers who are dealing with this problem and have not yet been offered a resolution. Thank you for your attention to this matter. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Description of Incident: The engine in my 2020 Hyundai Palisade Limited failed and ultimately seized despite having been regularly maintained and receiving an oil change less than 3,000 miles prior to the failure. The component that failed was the engine, and according to the dealership, it is seized and no longer operable. The vehicle is currently at the dealership and available for inspection upon request. Safety Risk: The failure posed a significant safety risk. The engine began shaking while the vehicle was in motion, creating a sudden loss of power and drivability. I pulled over immediately and discovered that the engine oil dipstick was dry. I added oil right away, but the engine shut down shortly after. The abrupt loss of engine function while driving could have led to a serious accident had I been in traffic or at highway speed. Reproduction / Confirmation: Yes, the issue was confirmed by Hyundai at Courtesy, a certified Hyundai dealership. They diagnosed the engine as seized and also confirmed that oil was present at the time of inspection, ruling out owner neglect. Inspections Conducted: The vehicle and failed component (engine) have been inspected by the dealership, who submitted a case to Hyundai. However, the case was denied for goodwill coverage despite the circumstances. The manufacturer has been notified but has not physically inspected the engine themselves beyond the dealership’s report. Warning Lamps or Symptoms: No Check Engine Light, oil pressure warning, or any dashboard message illuminated prior to or during the failure. The only symptom was engine shaking, which began just before the engine shut down. The oil loss occurred silently and without warning, making the issue especially dangerous and difficult to detect in time.

Engine is burning Oil at a rate that requires me to put 2 quarts of full synthetic oil every 2-3 weeks in my car. Hyundai is ignoring this problem and dealership says my engine is burning in a normal range. This is a known issue with these engines at hyundai over the past few years and if it is burning that much oil without any leaks there is no way that is safe.

The driver side wiper stopped functioning during a rain storm. Fortunately, I was not on a major road and was able to navigate. If I had been on the highway, I would have been blinded and potentially in a major accident if not able to pull over expeditiously. This malfunction occurred approximately one year earlier and was corrected by the dealer at that time. I believe some Hyundai Palisades have had a recall for this issue in the past. I am concerned that this has recurred and not been fixed definitively. This issue has potential fatal consequences. I am taking the vehicle to the dealer tomorrow to address the issue. I cannot take it today as it is still raining and I would be placing myself and others at risk.

1. Left-Side Captain Chair: Upon braking or movement slightly --the seat will come unsecured and jolt forward - causing whomever passenger who sits in it to move forward. 2. Tailgate Locking Lever: Trunk no longer opens upon pressing the button on the exterior. Trunk only opens upon utilizing the safely unlocking feature inside the vehicle - for emergencies only. Should not fail after 4 years. 3. Engine Burning Oil: July 2024 refilled oil change - December 2024 - Four (4 ) quarts of oil lost - vehicle is burning oil at unreasonable rates
