Filed Oct 28, 2026 · Engine, Fuel system · FL

• Noticed a rattle sound when taking off and when the car was preparing to stop; All timely maintenance were done at Headquarter Hyundai in [XXX]. Oil change was done by Tires Plus ([XXX]) end of XXX as the car was just over 100k miles, so no warranty. • XXX, notice the rattle sound and notice the engine tremble when stopping. Returned to Tire Plus for diagnostic. XXX - TECH NOTED NO OIL ON DIPSTICK UPON ARRIVAL. CUSTOMER ADVISED TO DO OIL CHANGES MORE FREQUENTLY AT 3,000 MILE INTERVALS; NO VISIBLE OIL LEAKS AT THIS TIME - INTERNAL ENGINE OIL CONSUMPTION. POTENTIAL PISTON RING OR ENGINE BEARING ISSUE CAUSING OIL CONSUMPTION. COMPUTERIZED ENGINE ANALYSIS. • My safety was at risk when the oil notification failed to occur, when the check engine notification failed to occur. These failures could have resulted in a complete shut down of the engine resulting in an immediate collision as I travel on the interstate daily for work.

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 miles — 3.5 quarts low on a 6.1-quart system. On 09/02/2026 the vehicle FAILED an official oil consumption test at Hyundai of Kirkland and was held for service. The dealer performed a carbon-cleaning procedure, but the underlying oil consumption is unresolved and a re-test is now underway. Running an engine at less than half its oil capacity risks sudden seizure or stall at speed. I am concerned this is a systemic defect affecting other 2020 Palisades and request the federal safety agency investigate.

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 safety measures. Indisputable Failure Data: Between 99,xxx miles (under warranty) and 103,xxx miles, the engine consumed 5.5 quarts of oil over a 3,000-mile interval. This equals an extreme burn rate of 1.83 quarts per 1,000 miles. Hyundai’s maximum corporate failure limit (1.0 qt/1,000 miles). Secondary diagnostics indicate this massive volume of un-combusted oil is actively pushing into the exhaust system, creating restrictive backpressure that induces stalling. Timeline & Dealer Obstruction:Rusty Wallace Hyundai: Inspected vehicle under 100,000 miles and initiated the first 1,000-mile consumption test, but subsequently refused documentation and further warranty services. A corporate national claim and customer service complaint were filed against them.Grayson Hyundai: Completed a second 1,000-mile test documenting a definitive failure. They confirmed this is a common, known systemic issue and recommended full engine replacement.Federal Violations: Under the Magnuson-Moss Warranty Act, because the defect was reported to a dealer before warranty expiration, Hyundai is legally required to cover the defect. Forcing a vehicle that burns 5.5 quarts of oil onto public roads also violates strict EPA Clean Air Act emissions compliance standards. Hyundai's current demand for out-of-pocket payment must be rescinded for full corporate coverage.

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 then authorized a combustion-chamber cleaning. On May 12, 2026, at 91,087 miles, the dealership completed the follow-up test and stated that the vehicle passed at that time. On September 14, 2026, at 95,512 miles, I returned to the dealership because the engine again had no measurable oil remaining. Only 4,425 miles had elapsed since the May oil change. The dealership’s repair order states that the vehicle “has no oil again.” I also reported that the vehicle had begun stuttering and rattling when pressing the brake and coming to a stop, creating concern that the engine may already have sustained damage from insufficient lubrication. The dealership initiated another oil-consumption test and instructed me to return after 1,000 miles. However, the earlier combustion-chamber cleaning did not correct the underlying problem. I am concerned that the vehicle may again consume its oil without adequate warning and could stall, seize, or lose power while being driven, placing the occupants and other motorists at risk. Hyundai should investigate the cause of the recurring oil loss and determine whether 2020 Hyundai Palisade vehicles have defective piston rings, cylinders, valve components, PCV systems, or other engine components causing excessive oil consumption. I am requesting that the federal safety agency document and investigate this potentially dangerous engine defect.

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. The oil is burning internally within the combustion chamber. This creates an extreme safety risk. If the oil level drops dangerously low before the next service, the engine is at risk of sudden catastrophic failure, severe overheating, or immediate stalling while in motion. A sudden loss of propulsion while driving in heavy traffic or at highway speeds places myself, my passengers, and other drivers at risk of a serious collision. Furthermore, the lack of an early warning sensor or dashboard indicator for low oil volume means the driver is left entirely unaware of the hazard until the engine begins to fail. Hyundai is well aware of this widespread oil-burning defect in their V6 engines, yet because my vehicle has reached 160,000 miles, they refuse to provide any diagnostic support, remedy, or warranty assistance. I am requesting that the federal safety agency open a formal investigation into the 2020 Hyundai Palisade engine oil consumption defect to compel the manufacturer to issue a safety recall before a catastrophic stalling event causes a fatal accident.

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 requesting that Hyundai explain exactly what requirement my vehicle allegedly failed to meet and provide documentation supporting the denial.I am requesting that Hyundai reverse the denial and fully cover the necessary engine replacement under warranty. I also request a complete review of my maintenance history, repair records, oil-consumption test results, diagnostics, and the dealership’s submission. This vehicle has been properly maintained and has only approximately 80,000 miles. I purchased it expecting a reliable vehicle that would last many years. An engine developing excessive oil consumption at this mileage is unacceptable, and I believe Hyundai should stand behind its product and warranty obligations.

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 at traffic lights. The technician found no measurable oil on the dipstick, 4.5 quarts low, and found the camshafts out of time as a result. On 11/25/2025 at 69,851 miles the oil light flickered and the engine ran rough and stuttered. The dealer checked the dipstick and again found no oil on it at all. This was only 5,614 miles after a documented oil and filter change performed by that same dealer. No warning illuminated until the crankcase was already effectively empty, which I consider inadequate warning of imminent engine failure. Consumption has continued and worsened: 1 quart low at 77,202 miles (4/22/2026), 1.5 quarts low at 81,350 (5/14/2026), and 1.2 quarts low at 82,927 (8/11/2026), the last only 1,577 miles after an oil change. Hyundai TSB 23-EM-008H sets the failure threshold at 1 quart per 1,000 miles for all gasoline engines. The dealer twice billed Hyundai operation code 21000FCC, which that bulletin defines as payable only after an initial oil consumption test result of NG (failed). Two combustion chamber cleanings were performed at Hyundai's expense (1/2026 and 5/2026). Neither resolved the consumption. On 5/14/2026 the dealer submitted a request to Hyundai Motor America to replace the engine. Hyundai denied it verbally and has provided no written decision, case number, or reason. This is our family's primary vehicle and remains in service. I must check the oil weekly to keep the engine from running dry. Complete dealer service records are available.

The vehicle suffers from a severe manufacturing defect causing excessive engine oil consumption (burning more than 2+ quarts per 1,000 miles) with no warning lights or oil pressure indicators activating. With little to no warning, I could be driving and experience catastrophic engine failure. This defect creates an immediate safety hazard, as sudden engine seizure or stalling at highway speeds risks loss of power braking and steering, creating an imminent risk of a high-speed collision. The dealership has confirmed the oil consumption issue after we noticed the vehicle stalling and performing sluggishly until the oil was changed.

I bought this car used from Albion Ford and I didn't have it 3,000 mile when my check engine light came on. Took it in and they said nothing was wrong with it. A couple days later it stalled in the middle of the road at a stop sign. It happened a mile later, I stopped at the store and there was absolutely not oil on the dip stick. I put 2 quarts in and it was at the very bottom of the dipstick. It's still under warranty and they did an oil consumption test and said it was normal. It's burning 5.5 quarts every 3,000 miles.

Description of IncidentThe vehicle experienced a severe engine system defect and catastrophic internal mechanical failure. The primary symptom prior to the failure was excessive, rapid engine oil consumption between scheduled maintenance windows. The issue was officially confirmed by an authorized dealership service center, where diagnostic testing verified that the engine has critically low cylinder compression in Cylinder 1. The vehicle is currently completely incapacitated, and the disassembled engine block remains at the dealership facility available for inspection upon request. Safety Risk AssessmentA sudden and severe loss of internal engine cylinder compression creates a critical vehicle performance defect, an immediate stall risk, and a catastrophic hazard when operating on high-speed roadways. In this instance, the mechanical failure completely disabled the household’s primary, medically modified means of transport. Because the manufacturer and dealership failed to maintain or provide a structurally or layout-compliant alternative vehicle, a permanently disabled occupant was forced into a tight, non-accommodated cabin geometry. This directly induced severe physical trauma, muscle spasms, and an immediate loss of lower extremity neurological sensation while operating the replacement vehicle. The combination of a catastrophic powertrain failure and a total refusal by the dealer and manufacturer to provide an accessible replacement layout has completely stripped a vulnerable consumer of independent mobility and created a severe, ongoing physical safety hazard.

My properly maintained 2020 Hyundai Palisade suffered catastrophic engine failure at 77,000 miles. Importantly, prior to the engine failure, no check engine lights, low oil warnings, or other warning indicators were active or displayed. The vehicle gave no indication of an imminent catastrophic engine failure or lack of oil. In researching this matter, I have found numerous reports, as well as active and settled litigation, involving Hyundai engine failures and oil consumption concerns. Severe oil starvation due to engine manufacture issues caused a thrown rod which can result in fire. The car was being driven by my teenage son after dark and the engine completely shut down putting him in harm's way in the middle of the road. Hyundai has repeatedly refused my requests for assistance in repairing this known issue due to my being a second owner with a lesser warranty that is given to 1st owners. This issue is a safety concern and a known issue to HCA and should be a recall to insure it stops happening.

On XXX I took my vehicle to Ourisman Hyundai of Bowie because my engine light was on. That same day the Service Adviser (Edson XXX) informed me that the engine was burning oil excessively. They performed an oil change and replaced engine oil gasket and asked me to return after driving 1000 miles. Mileage at the time was 103,380. I return on XXX, mileage was 104,580. [XXX] informed me that vehicle failed oil consumption test. He submitted request for engine replacement. On 11/25/2025 I returned to dealer because engine light came on again, and still no approval for engine replacement. I was informed that Hyundai approved combustion chamber cleaning. The service was complete four days later. However, it did not fix the problem. The engine excessive oil burn still happens as of this report.
