All 4 Known Issues
The 3.8L Lambda II V6 in the Palisade can suffer from fuel diluting the engine oil, particularly in cold climates with short trips. The GDI system can allow unburned fuel past the piston rings during cold starts. Oil level rises above the full mark and smells of gasoline. Hyundai released a software update to address the issue.
Common Symptoms
- Oil level rising above full mark
- Gasoline smell from dipstick
- Oil looks thin and watery
- Rough idle in cold weather
- Fuel smell inside cabin
How to Fix
Have the dealer install the latest ECU calibration to reduce fuel enrichment during cold starts. Change oil more frequently in winter (every 3,000-5,000 miles vs 7,500). Use 0W-20 full synthetic oil. If oil level is significantly above the full mark, drain and replace immediately. Software update is free; extra oil changes cost $50-80 each.

- UpgradePennzoil Platinum 0W-20 resists fuel dilution better than many conventional oils (Pennzoil Platinum Full Synthetic 0W-20)
- TipIn cold weather, drive at least 15-20 minutes to get the engine fully warmed up - short trips cause the most dilution
- TipCheck oil level and smell the dipstick monthly in winter months to catch dilution early
Palisade headlight assemblies are prone to moisture intrusion and internal condensation, significantly reducing nighttime visibility. The issue stems from inadequate sealing of the LED headlight housing. Some owners have had multiple headlight replacements under warranty, only for the issue to return.
Common Symptoms
- Visible condensation inside headlight
- Reduced headlight brightness
- Water droplets visible inside lens
- Headlight flickers
- One headlight appears dimmer than the other
How to Fix
Document the condensation with photos and bring to dealer under warranty. Hyundai has updated headlight assemblies with improved sealing (newer part numbers). If out of warranty, a headlight assembly replacement is $800-1,500 per side. Some owners have had success drilling a tiny drain hole and applying silicone sealant as a temporary fix.
What Owners Are Using
Parts and tips from 480+ owners who fixed this issue
- TipTake timestamped photos of condensation and file a NHTSA complaint to build the case for a broader fix from Hyundai
- TipRequest the updated/revised headlight assembly part number from the dealer - early production units had worse sealing
- NoteDo not attempt to open the headlight housing yourself - this voids the warranty on the assembly
The 8-speed automatic transmission in the Palisade can exhibit harsh 1-2 and 2-3 upshifts, delayed downshifts when passing, and occasional harsh engagement from park to drive. The TCM calibration is the primary issue, though some cases involve valve body wear. Hyundai has released multiple software updates to improve shift quality.
Common Symptoms
- Harsh jolt on 1-2 upshift
- Delay when pressing gas to pass
- Clunk shifting from park to drive
- Hunting between gears on hills
- Transmission hesitation at low speed
How to Fix
Request the latest TCM software update from the dealer (free under warranty). Ensure transmission fluid is at the correct level and condition. If harsh shifting persists after software update, the valve body may need replacement ($800-1,500). Full transmission fluid change (not flush) every 30,000 miles with Hyundai SP-IV-RR fluid.
What Owners Are Using
Parts and tips from 350+ owners who fixed this issue
- UpgradeUse only Hyundai SP-IV-RR ATF for fluid changes - incompatible fluid causes shift issues (Hyundai SP-IV-RR ATF)
- TipAfter a TCM update, the transmission needs 500-1,000 miles of driving to fully relearn your driving patterns
Many Palisade owners report a persistent foul odor inside the cabin, described as a chemical or locker-room smell. The source has been traced to the Nappa leather headrests and interior trim materials off-gassing. The smell is worse in warm weather and returns even after cleaning. This was a widespread complaint in early production models.
Common Symptoms
- Chemical or musty smell in cabin
- Odor worse in warm weather
- Smell returns after cleaning
- Headrests smell when held close
- New car smell that turns unpleasant
How to Fix
Hyundai issued a customer satisfaction campaign replacing headrests in affected vehicles. Contact your dealer to check eligibility. For DIY treatment, clean headrests with a leather cleaner and apply Leather Honey conditioner. Using an ozone generator ($30-50 rental) can temporarily eliminate the odor. Dealer headrest replacement is free if covered.
