   My 2020 Hyundai Palisade (3.8L V6) has a persistent engine defect causing sudden stalling and severe oil consumption. Since mid-2019 the engine has stalled without warning when coming to a stop, idled roughly, and made loud puttering noises under light acceleration — a loss-of-power hazard in traffic. In 2026 the dealer began formal oil consumption testing. Although 1,000-mile checks were marked 'passed,' the engine was found completely dry (dipstick showed no oil) at 2,000…

   Defect & Safety Hazard: Severe internal manufacturing defect causing catastrophic engine oil consumption and sudden, un-warned engine stalling. The vehicle completely shuts down at highway speeds, on inclines, and at stops. This sudden loss of motive power deactivates power steering and braking assists, creating an immediate multi-vehicle collision risk. No low-oil or dashboard indicators illuminate prior to stalling, stripping the driver of any ability to take proactive…

   I am reporting severe and recurring oil consumption in my 2020 Hyundai Palisade that could cause engine damage, engine seizure, stalling, or a sudden loss of power while driving. On April 14, 2026, at approximately 89,950 miles, an authorized Hyundai dealership documented that the engine had consumed approximately 1.3 quarts of oil in only 1,275 miles, equivalent to approximately one quart every 982 miles. The vehicle failed Hyundai’s initial oil-consumption test. Hyundai…

   I am filing this safety complaint regarding excessive oil consumption in my 2020 Hyundai Palisade, which presents a direct vehicle stalling and engine failure hazard while driving at highway speeds. My vehicle is currently consuming approximately 5 quarts of engine oil every 3,000 miles. This severe oil loss occurs rapidly between scheduled maintenance intervals without any illuminated dashboard warning lights, low oil pressure indicators, or visible oil leaks on the ground.…

   I do not understand how Hyundai can approve its required testing process, have the vehicle fail that test, and then deny the engine replacement resulting from those findings. This is unfair and raises serious concerns about how Hyundai is applying its warranty procedures.Hyundai’s published oil-consumption procedures establish a process for diagnosing excessive oil consumption and determining when further repairs, including engine replacement, may be warranted. I am…

   On August 14, 2026, while driving and decelerating, I heard a knocking sound from the engine and the vehicle had difficulty downshifting. As the transmission shifted from second gear to first, the engine stalled immediately and the vehicle dropped into neutral while on the roadway. I lost propulsion in traffic. The vehicle behind me nearly rear-ended us due to the sudden stall. My children were in the vehicle. All dashboard warning lights illuminated at the moment of the…

8. Filed Aug 25, 2026NCEngine

   My 2020 Hyundai Palisade (3.8L GDI Lambda II V6) consumes engine oil at a rate that empties the crankcase between scheduled oil changes, with no warning lamp illuminating before the oil is gone. This creates a risk of engine seizure and sudden loss of motive power in traffic. The vehicle has repeatedly run rough and felt as though it would stall when slowing or stopping. On 3/10/2025 at 57,026 miles I brought it to a Hyundai dealer because it felt like it was about to stall…

   This vehicle has suffered two identical, catastrophic electrical failures causing an immediate and total loss of engine power while traveling at highway speeds. The first incident occurred after the engine was replaced under a Hyundai extended warranty. The dealership service department blamed that failure on a loose engine ground strap and released the vehicle back to me. On August 3, 2026, the exact same failure occurred for a second time while driving at high speed on the…
