2022 Hyundai Palisade Fuel system Problems

purchased a vehicle that has experienced ongoing mechanical and safety-related defects, including excessive oil consumption, seat belt malfunctions, and unresolved injector recall issues. Despite multiple repair attempts by the dealership, the problems continue to persist and have not been permanently corrected. These defects substantially affect the vehicle’s safety, reliability, value, and everyday use. The dealership and manufacturer represented the vehicle as reliable and safe; however, the repeated failures and unresolved recalls suggest otherwise. I believe it is misleading to continue selling or servicing vehicles with known defects that cannot be properly repaired. I have also learned that certain model years are no longer sold due to widespread malfunctioning issues that are costly for consumers to repair, yet I was not informed of these concerns at the time of purchase. I have made several attempts to resolve this matter by bringing the vehicle to the dealership for repairs, reporting the recurring issues, and complying with recommended service appointments. Despite these efforts, the defects remain unresolved, causing financial hardship, inconvenience, and concerns for my safety.

Hyundai's recent emissions software update (9C9) has disabled engine braking, creating a risk of brake fade on grades. The vehicle is no longer able to hold speed while descending grades, regardless of downshifting, forcing the brakes to be implemented to avoid excessive speed. This was never an issue prior to the software update and happened immediately after the software was installed. Instead of holding the vehicle with the engine (foot off the gas, and downshifting) the engine will continue to increase speed up to the point of approaching maximum RPMs. Further evidence of this behavior is that trying to use the engine braking no longer shows maximum MPG on the dash, indicating the software update is still feeding fuel to the engine with the foot off the gas.

Since purchasing the vehicle brand new in Oct 2021, all recommended services have been executed on time. (records to prove it can be provided if required) Aug 25, 2025. Mileage = 78,247. Full preventative maintenance including GDI Fuel Service and Oil change Nov 21, 2025. Mileage = 85,421. I am on a 2 hour commute home and the engine is stalling at every stop. Needs to be re-started each time. Pinging noise when accelerating. The car is brought into Parkway Hyundai in Wilmington, NC. Oil was below dipstick. This lack of oil causes the engine to misfire. I asked why the "low oil" light doesn't appear. I am told that he didn't know but the light only goes on when its completely out of oil. That doesn't seem safe at all. At this point, I am told by Service agent that this is a known problem with Hyundai and the recommend bringing the vehicle in for oil checks every 1,000 miles Dec 15, 2025. Mileage = 86,597. Oil check - Engine 0.4 quarts low after 1,000 miles. I am told it is "within Hyundai's range of acceptance Jan 2, 2025. Mileage = 88,463. Oil check - Engine 1.4 qts low after 2,000 miles. I am told 0.75 quarts every 1,000 miles is within the accepted range. Jan 22, 2025. Mileage = 89,487. Oil check - Engine 0.9 qts low after 1,000 miles. I am told 0.9 qts is within Hyundai's accepted range. This is unacceptable for a car to burn almost a quart of oil every 1,000 miles.

I am writing to formally submit a complaint regarding multiple ongoing and serious issues with my 2022 Hyundai Palisade. These issues not only diminish the performance and reliability of the vehicle but also raise significant safety and quality concerns. Below are the problems I have encountered: 1.Thermostat and Coolant System Defects: Like many other owners of the 2022 Hyundai Palisade, I have experienced problems with the thermostat and coolant system. My vehicle has exhibited signs of overheating, posing risks to the engine’s longevity and safety. 2.Radiator Leak: I have identified a radiator leak, which is troubling for a relatively new vehicle. This suggests a defect in the materials or assembly, as this should not be occurring under normal operating conditions. 3.Oil Pan and Filter Housing Issues: •The oil pan has developed a crack, which is highly unusual, especially since Hyundai has performed all of my vehicle’s oil changes. This raises concerns about part quality and service handling. •Additionally, I have noticed oil leaking from the oil filter housing. This leak not only raises concerns about engine performance but also indicates a potential flaw in the design or installation of the oil filter system. 4.Faulty Sensors: My vehicle’s sensors frequently activate without any nearby objects or obstacles. These false alerts are a serious distraction while driving and undermine the effectiveness of the car’s safety features. 5.Key Fob Malfunctions: While driving, I have repeatedly encountered the “key not in vehicle” warning, despite the key being present inside the car. This issue is not only an inconvenience but also a potential safety risk if it disrupts the vehicle’s operations unexpectedly. The combination of these defects is unacceptable for a vehicle of this age and reputation. These problems suggest significant flaws in manufacturing, design, or maintenance practices that Hyundai should address immediately.

In April 2022, we purchased a new 2022 Hyundai Palisade from a dealership due to persistent issues with our previous Hyundai Santa Fe, which had ongoing engine problems and recalls. After multiple unsuccessful repairs and software updates on the Santa Fe, we decided to trade it in for the Palisade. Since the purchase, the Palisade has undergone over ten warranty-related repairs. In early 2023, an oil consumption test revealed significant warranty concerns, leading the dealership to keep the vehicle for additional diagnostics. This process lasted nine months and included a full engine replacement. During this time, my husband filed a complaint with Hyundai Corporate, seeking a lemon law buyback or an equivalent trade-in. Hyundai Corporate denied our request, stating that we did not qualify under the lemon law and refusing to buy back or offer a fair trade-in for the vehicle. In June 2024, after nearly a year of repairs, we retrieved the vehicle, only to experience severe issues shortly afterward. The Palisade began jerking and shaking on the highway, and the check engine light came on. The dealership identified a faulty mass air flow sensor and ordered parts for its repair. They assured us it was safe to drive until the repair was completed. However, the next day, the vehicle displayed the same issues. A diagnostic at Auto Zone revealed problems with both the air flow sensor and the fuel injector, indicating unsafe driving conditions. We returned the vehicle to Hyundai College Station, where we received a loaner car while they conducted repairs. During this period, we were informed of a "computer digital data hack" that prevented the dealership from providing documentation of the services performed. When we picked up the Palisade, we were told that only the mass air flow sensor had been repaired, with no work done on the fuel injector or other issues. Currently our vehicle exhibited engine defaults and the engine light came on. It is at Principle Hyundai for repairs
