2020 Hyundai Palisade

I was recently involved in an accident with my 2020 Palisade that I believe may have been caused by a brake failure. I was simply moving the vehicle from one part of a driveway to another when, as I drove over a drainage ditch, the brakes did not respond and the car suddenly accelerated into a tree. I sustained facial injuries and was transported by ambulance to a nearby hospital. The vehicle is currently at Canby Motors in Bel Air and is available for inspection. The vehicle has only been inspected by Canby Motors to my knowledge at this time. There were no warning lamps, messages or other symptoms of the problem prior to the failure.

The sunroof wind deflector broke when I simply opened the sunroof, and the sunroof is now stuck in the open position. I wish TSB 23-BD-003H-1 would've included my VIN so I could've addressed this issue prior to it breaking. Now I am faced with a $3400 repair bill from Hyundai. Hyundai said there is no cheaper option to partially fix it to at least get it closed. Other repair shops are referring me to Hyundai to complete the repair.

The contact owns a 2020 Hyundai Palisade. The contact stated that while the vehicle was parked, the contact checked the oil level and became aware that the oil level was low. No warning lights were illuminated. The vehicle was taken to the dealer, where an oil consumption test was performed. The contact was informed that the oil consumption test results indicated that the vehicle was operating properly. The contact stated that it was not normal to add oil every 1,000 miles driven. The contact stated that one quart of oil was added every 1,000 miles. In addition, the contact stated that the recommended oil change was at 5,000 miles. The manufacturer was made aware of the failure but no assistance was provided. The failure mileage was approximately 92,000.

Safety Complaint Summary: I am filing a safety complaint regarding my 2020 Hyundai Palisade SEL AWD, ~96,000 miles). This vehicle has suffered three major powertrain failures under 100,000 miles: - Full engine replacement (due to excessive oil consumption, unresolved for months) - AWD system repairs - Now requires a full transmission replacement When my engine began burning oil, Hyundai’s service department charged me ~$500 and sent me back on the road without disclosing that this was a known issue. I continued running out of oil multiple times until an independent mechanic diagnosed the defect. My family was unknowingly placed at risk while Hyundai delayed resolution for 8 months. Diminished Value: The repeated nature of these failures not only raises safety concerns but has also destroyed the market value of the vehicle. Even after a transmission replacement, the Palisade remains a car that no buyer would trust — which underscores the seriousness of these systemic safety risks. Relief Requested: I ask NHTSA to review whether this defect pattern represents a broader safety issue and whether Hyundai should have disclosed the known oil consumption defect earlier and should investigate why a vehicle is suffering three powertrain issues and if this is a wider problem with the car type/year. A notice to consumers should be issued so we are not driving around in an unsafe car.

SUV is consuming oil prior to 5000 miles. I went to the dealer in June after noticing my SUV shuttering and almost shutting off while accelerating and it was noted that all of my oil was gone. I was instructed to get an oil change. I came back a month and a half later and all of my oil was gone again and it had been less than 5000 miles since the last oil change. I was instructed to get another oil change and come back in 1000 miles. It has been 3 weeks and I came back 1000 miles later with most of the oil gone. Diagnostic showed internal damage and the valve seal is leaking internally. There were no warning lights. I am waiting for further inspection by the dealer.

The contact owned a 2020 Hyundai Palisade. The contact stated that while driving at approximately 65 MPH, he heard an abnormal popping and hissing noise. The contact stated that he started to smell a burning odor. The contact was losing forward momentum. No warning lights illuminated. When he applied the accelerator pedal, the vehicle continued to slow down. The contact pulled off the highway, stopped the vehicle, and turned off the engine. The contact stated that almost immediately, smoke was issuing from under the front end. The contact stated that the vehicle burst into flames. The police and fire department were called. The fire was extinguished using chemicals. The police and fire departments issued reports. The vehicle was towed away to an impound lot. The contact stated that he had the transmission replaced in 2024. The manufacturer was not informed of the failure. The failure mileage was approximately 150,000.

While merging onto a highway, my 2020 Hyundai Palisade abruptly lost all engine power and stalled. This immediate and complete failure occurred at a critical moment, posing an extreme safety risk. All dashboard warning lights illuminated, but provided no specific diagnosis. The vehicle was towed to a dealership, where technicians determined the engine was consuming oil at an abnormal rate, despite a lack of visible leaks. I was instructed to participate in an "oil consumption test," a three-part process that required multiple oil changes and inspections over several months. Each time, the vehicle had burned over a quart of oil—a clear indication of a defect. Despite this evidence, Hyundai denied my warranty claim, accusing me of negligence for being unable to produce oil change records between 29,600 and 46,900 miles. This is a common and unacceptable tactic used to avoid accountability for a widespread issue. My experience is not isolated. Hundreds, if not thousands, of owners of 2020-2023 Hyundai models, including the Palisade, report identical engine oil over-consumption issues and subsequent power loss. This issue is a **severe safety hazard** that can lead to sudden, catastrophic engine failure and potential accidents. Hyundai's refusal to acknowledge this defect and issue a recall is **gross negligence**. They are knowingly allowing thousands of unsafe vehicles to remain on the road. There are currently federal lawsuits against Hyundai for this very issue. The transportation authority must force Hyundai to issue an immediate recall and remedy this critical defect before a tragedy occurs.

Rear shocks leaking and fail inspection. This was confirmed by both the dealer and independent service center. There were no warnings. This is the second time the same shocks have needed to be replaced. The first time they lasted 3 years, the second time two years. This is an endemic problem with these shocks affecting both the original and OEM replacement parts.
