I am the original owner of a 2021 Hyundai Palisade SEL AWD (74,225 miles) reporting repeated engine shutdowns in traffic, severe rough idling, and an unresolved safety concern. The problem began XXX. I first brought the vehicle to Hyundai on XXX and have sought service approximately four times since June. Despite technicians stating they could not reproduce the issue, the engine stalled again on XXX after I picked it up from service. The dealership also instructed me to complete a 1,000-mile oil consumption test. When I returned after 750 miles, I was told I had returned too early. The engine subsequently shut off twice on XXX. Documented incidents: XXX 1:53 PM: Engine shut off on [XXX]. XXX, 5:38 PM: Engine shut off on [XXX]. XXX, 5:08 AM: Engine shut off at [XXX] exit, [XXX] XXX 11:35 AM: Engine stalled at [XXX]/[XXX]. XXX, 12:30 PM: Engine stalled at [XXX]/[XXX]; check engine light illuminated. XXX, 10:57 AM: Near-stall with severe rough idling at Los Gatos Farmers Market. After further rough idling, the check engine light remained illuminated. On XXX the dealership service advisor personally experienced severe rough idling and an apparent near-stall while moving my vehicle, with the check engine light on. I heard her acknowledge the issue. The vehicle remains at the dealership. I provided a written incident log and opened Hyundai case #XXX. Repeated engine shutdowns at intersections and freeway exits pose a serious collision risk. I request the federal safety agency investigate this potential safety defect. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle experienced severe engine stalling and critically low oil levels that were officially documented by an authorized dealership well before 100,000 miles (at approximately 79,000 miles). Because this pre-existing condition remained unresolved under warranty, the engine ultimately failed and required a complete replacement at approximately 103,000 miles. Just 7,000 miles later, at 110,000 miles, the automatic transmission suffered a critical failure. The transmission severely shudders, spikes to excessively high RPMs, and refuses to shift properly through lower gears (gears 1 to 3). This causes sudden hesitation, loss of motive power, and violent jerking when accelerating and merging into active traffic, creating an imminent crash hazard. The manufacturer has refused repair assistance despite cascading powertrain defects that originated prior to 100,000 miles.

Due to a known oil consumption issue the manufacture replaced the engine using a short block swap, they used the old fuel injectors and during the swap one of them failed, becoming stuck open. Now they refuse to fix it without me paying for labor. The failed fuel injector occurred immediately following a mandatory manufacturer engine replacement and poses a thermal/fire hazard.

Whatever you do, do not purchase a Hyundai vehicle. Their engines are defective. On XXX, I brought my car in for service at Castle Hyundai, [XXX]. I informed the service representative that I was having issues with my car stopping and automatically applying the braking system intermittently. They looked at the car and said they saw nothing was wrong. They charged me $940.30 for diagnostics and replacing a couple of belts and oil filter housing leak. I started having the same issue in XXX and I brought my car in again. This time they told me that my car was burning oil internally and that I would have to have a Combustion Chamber Cleaning. I was informed by the Service Manager that this was a common problem with my vehicles model year and that if was a requirement to for the Warranty people to initiate changing the engine. I paid $1,094.26 for this service. I was told to bring the car back after driving the car an additional 1,000 miles. I was also told by that service manager that his dealership changes about 200 engines a month due to this issue. I took the car back to the dealership after driving the 1,000 miles. I sent them photos of the 3 oil changes I could find documentation for, and I had one done at this dealership. I was informed by the dealership that the warranty company and Hyundai when asked, refused my claim. I called the warranty company myself and they would not uphold my claim. I then contacted the Regional Case Manager, and they tried to tell me something different. They told me my car was over warranty and that the engine was only covered up to 60,000 miles. I have the Warranty in my hand, and it says lifetime warranty. This is not fair. I am [XXX] old and I bought the car with 31,000 miles on the car. I have consistent and periodic oil changes but could not remember all the places. This is the first Hyundai I have purchased and I am asking that my claim be upheld and executed s INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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 have been dealing with the oil consumption issues for this vehicle for about 2 years now. There are documented complaints and a class action lawsuit in California about this issue. Bottom line, the engine burns too much oil to be safely driven between oil changes without the owner checking and adding oil. My particular vehicle is burning just under 1 quart of oil per 1000 miles. Hyundai’s owner manual suggests changing the oil every 7,500 miles, but the oil capacity is under 6 quarts. At the current rate, I would run out of oil before the suggested oil change interval. This is a severe safety issue as engines require oil to run correctly, not overheat, and lubricate all the moving parts. The previous generation Hyundai models also had similar oil consumption issues. Those vehicles had a the federal safety agency campaign which resulted in Hyundai being responsible to fix the engines. I believe a recall is proper given the safety concerns noted above. At a minimum, Hyundai should stand by their work and fix the issues as they arise.

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.
