2020 Hyundai Palisade

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.

2020 Hyundai Palisade with Lambda II 3.8L GDI V6 (G6DJ) engine experienced complete engine failure due to oil starvation from excessive oil consumption through piston ring bypass. No oil warning light illuminated prior to failure. Engine consumed oil silently between service intervals until catastrophic failure. Vehicle became undriveable. HMA issued TSB 21-EM-003H addressing oil consumption in other Hyundai engine variants but explicitly excluded the Lambda II V6 (G6DJ) from the bulletin's scope despite the same piston ring bypass defect being present. HMA subsequently issued Campaign 9C9 referencing Palisade oil consumption but with no defined remedy and inadequate owner notification. Vehicle was purchased as a Certified Pre-Owned Hyundai. At time of CPO sale, HMA had documented knowledge of the Lambda II oil consumption defect. HMA denied warranty coverage for engine replacement, estimated at $12,000. HMA's own TSB establishes 1 quart per 1,000 miles as the threshold for defective consumption. Independent engineering analysis confirms the Lambda II G6DJ piston ring geometry produces oil bypass consistent with that defect threshold. Engine is available for inspection upon request. Defect was confirmed by HMA-authorized dealership oil consumption test. No warning lamps appeared prior to failure. This defect is believed to affect a large number of Lambda II-equipped vehicles sold in the [XXX]. Prior federal class action litigation (XXX v. Hyundai Motor America, C.D. Cal.) documented HMA's corporate knowledge of the Lambda II oil consumption defect prior to the date of this vehicle's CPO sale.

The engine burns oil excessively and the oil light does NOT come on when the oil is low. Our car is right at 90k miles, it began to shudder and malfunction out of the blue while we were driving on the highway. There was absolutely no indication the oil was low. Now the car will not turn on at all. We were in between oil changes. The safety of myself and my family was put at risk because the engine blew with no warning. The vehicle has been serviced repeatedly by Hyundai for this issue, and they are trying to tell us that it is normal for oil to completely burn out in between oil changes.

Driving down road in early afternoon at about 35 mph. Car began to run rough (jutter) then almost immediately stalled. The car’s engine icon appeared on the screen along with verbiage indicating service engine soon. After about 3-5 minutes, I started the car and drove it directly into a parking lot approximately 100 feet from where the car stalled. I had the car towed to a repair shop in town. The following day the service adviser called after doing diagnostics and indicated the car had no oil (It was approximately 3,400 miles since my last oil change). The technician explained there were some minute cracks in the oil filter cap but nothing that would warrant such a large loss of oil. An oil change was done, the oil filter cap was replaced with an aftermarket cap, and the car was returned to me. I have contacted the service department of the Hyundai Dealership where the car was purchased and am awaiting a call back.

I am filing this complaint regarding my 2020 Hyundai Palisade affected by the recall involving the third-row seat airbag not deploying properly and the risk of occupant ejection during a rollover accident. I purchased this vehicle in December 2024 and have experienced a pattern of ongoing mechanical failures, repeated dealership visits, lack of manufacturer support, diminished use of my vehicle, and financial hardship throughout ownership. Since purchasing the vehicle, I have completed more than 20 oil consumption tests requiring repeated 1,000-mile dealership visits. The issues became so severe that both the engine and transmission ultimately had to be replaced. The unresolved recall has now created an additional major safety concern for my family. Hyundai indicated a remedy was expected by the end of March, but as of now there is still no repair available. This has significantly limited the safe use of my vehicle because the third-row seating cannot safely be used for passengers due to the risk associated with the defective airbag system. This delay is causing financial hardship as well. I intended to use this vehicle through Turo for supplemental income but cannot do so because of the active safety recall. I also have upcoming family travel requiring use of the third row and may now be forced to rent another SUV at my own expense. I currently owe approximately $30,000 on this vehicle and am facing substantial negative equity due to the vehicle’s extensive repair history and unresolved recall status. I am concerned about both passenger safety and Hyundai’s prolonged delay in providing a remedy for a serious safety issue. I am requesting that this complaint be documented as part of the ongoing investigation and oversight regarding Hyundai’s handling of this recall and the delay in providing repairs to consumers.
