Common Problems & Known Issues

The 2020 Palisade's 3.8L Lambda II V6 (shared with the Kia Telluride) suffers from a catastrophic engine failure issue tied to piston/bearing defects, making it a high-risk used buy despite otherwise solid construction. Transmission cooler leaks and failed motor mounts are secondary concerns that pale compared to the engine grenade potential.

Catastrophic Engine Failure - Piston/Bearing/Connecting Rod Damage

Occasional · high severity
Typical onset: 40,000-90,000 mi
Symptoms: Metallic knocking or rattling from engine bay, especially on cold start, Check engine light with misfire codes (P0300-series), Metal shavings in oil during changes, Sudden loss of power or complete engine seizure, Oil consumption increasing rapidly
Fix: Complete engine replacement or rebuild required. Short block replacement is 18-24 labor hours; full rebuild with machining adds another 8-12 hours. Hyundai extended warranty to 10yr/100k on some VINs, but coverage is inconsistent. Many shops won't touch rebuilds—just swap in reman or salvage engine.
Estimated cost: $8,000-15,000

Transmission Oil Cooler Line Leaks

Common · medium severity
Typical onset: 50,000-80,000 mi
Symptoms: Red transmission fluid pooling under vehicle, usually passenger side, Transmission overheating warnings on dash, Slipping or delayed shifts after extended driving, Fluid level dropping between services
Fix: Cooler lines crack where they attach to the radiator or transmission. Replace both lines and flush transmission fluid. 2-3 labor hours. Sometimes the cooler itself needs replacement if debris contaminated the system (add 1.5 hours).
Estimated cost: $600-1,200

Failed Transmission Mounts

Common · low severity
Typical onset: 60,000-100,000 mi
Symptoms: Clunking during acceleration or deceleration, Excessive vibration at idle in Drive, Transmission 'thunk' when shifting into Reverse or Drive, Visible sagging or tearing on mount rubber during inspection
Fix: The passenger-side transmission mount fails most often due to weight and torque stress. Replace both front and rear trans mounts as a set. 2.5-3 labor hours with subframe access.
Estimated cost: $450-750

Windshield Wiper Motor Failure

Occasional · medium severity
Symptoms: Wipers stop mid-stroke or won't return to park position, Intermittent wiper operation or complete failure, Burning smell from wiper motor area, Wipers running slower than normal speed settings
Fix: NHTSA recall 22V-354 covers some VINs, but many fall outside recall parameters. Wiper motor assembly replacement requires cowl removal. 1.5-2 labor hours. Check recall status first—free if covered.
Estimated cost: $350-600

Side Curtain Airbag Deployment Issues

Rare · high severity
Symptoms: Airbag warning light illuminated, No obvious crash damage but airbag light persists, Codes related to curtain airbag circuit resistance
Fix: Recall 22V-772 addresses curtain airbags that may not deploy properly. Requires harness inspection and possible airbag module replacement. Covered under recall—verify VIN eligibility before paying. Dealer-only repair, 2-4 hours depending on findings.
Estimated cost: $0 (recall) or $1,200-2,000

Fuel Filter Clogging (Premature)

Occasional · low severity
Typical onset: 70,000-110,000 mi
Symptoms: Hesitation or stumbling during acceleration, Hard starting after sitting overnight, Loss of power under load, especially uphill, Check engine light with fuel trim codes
Fix: In-tank fuel filter assembly clogs earlier than expected, possibly from ethanol fuel deposits. Requires fuel tank drop. 2.5-3 labor hours. Replace with OEM filter/pump assembly—aftermarket units fail quickly.
Estimated cost: $500-900
Owner tips
  • Check your VIN for the Theta/Lambda engine recall—some 2020s got the 10yr/100k extended warranty; confirm before buying used
  • Change transmission fluid every 40k miles instead of Hyundai's 'lifetime' claim—cooler line failures contaminate fluid quickly
  • Inspect engine oil religiously for metal flakes; catch bearing wear early and you might salvage it with a short block instead of full engine
  • Avoid extended idle times in Drive with AC on max—transmission mounts and cooler lines hate the heat cycling
Hard pass unless you get ironclad proof of engine recall completion or recent engine replacement—the catastrophic failure risk outweighs the nice interior and warranty reputation.
