2022 Hyundai Palisade: sudden loss of power

Filed Nov 8, 2026 · Engine · FL

I am filing an immediate safety complaint regarding a severe engine defect on my vehicle and the manufacturer's dangerous diagnostic protocol. The vehicle is experiencing active engine failure symptoms, including [insert symptoms here, e.g., severe knocking, sudden hesitation, intermittent stalling, or a flashing check engine light]. I have clear video evidence of the failure, and the dealership's Shop Foreman inspected the vehicle and diagnosed it with an internal engine problem. Despite a formal diagnosis from their own Shop Foreman and video proof of the failure, Hyundai Techline is attempting to deflect liability by blaming a previously installed aftermarket oil filter. The dealership has since replaced the aftermarket filter with an OEM filter. However, instead of repairing the diagnosed internal engine defect, they are forcing me to drive this malfunctioning vehicle for an additional 1,000 miles to "duplicate" the issue. Operating a vehicle with a known, documented internal engine failure on public roads poses an immediate and severe safety hazard to myself, my kids, and other drivers. The vehicle is at imminent risk of sudden engine stalling, complete power loss, or catastrophic mechanical seizure at highway speeds, which could cause a serious collision. The manufacturer is actively demanding that I operate a dangerous vehicle as a condition of their warranty process, shifting extreme physical liability onto the consumer.

Vehicle: 2022 Hyundai Palisade, approximately 78,000 miles. The vehicle has experienced a recurring engine/powertrain malfunction involving engine stalling, hesitation/rough operation, startup rattling, cylinder air/fuel imbalance, and misfires. The exact failed component is currently UNKNOWN. The vehicle is available for inspection upon request. The vehicle has stalled at low speeds, creating a safety concern because the engine can unexpectedly shut off or lose power while the vehicle is being operated in traffic. Unexpected stalling could leave the vehicle without normal acceleration when entering or crossing traffic and creates a risk of a collision involving the occupants or other motorists.The vehicle has been evaluated and serviced by a Hyundai dealership for engine-related concerns. Diagnostic trouble codes associated with these problems have included P000C, P219D, P219F, P21A0, and P0302. Of particular concern, P219D, indicating a Cylinder 2 air/fuel ratio imbalance, has occurred repeatedly, and the vehicle subsequently generated P0302, indicating a Cylinder 2 misfire. This suggests a recurring problem involving the same cylinder, although the underlying cause remains UNKNOWN.Previous repair efforts have included work involving the vehicle's VVT system, but the engine-related problems and diagnostic codes have continued/recurred. The vehicle/component has been inspected by a Hyundai dealership. To my knowledge, it has not been separately inspected by police, insurance representatives, or the federal safety agency. Whether Hyundai corporate/manufacturer representatives have directly inspected the vehicle is UNKNOWN.Prior to and during these incidents, symptoms included the check-engine warning light, startup rattling/noise, engine hesitation/rough operation, and stalling at low speeds. Diagnostic codes were stored when the check-engine light appeared. The problems have occurred on more than 100 occasion rather than being a single isolated incident.

On April 17, 2026, while driving my 2022 Hyundai Palisade with approximately 167,000 miles, the vehicle suddenly lost engine power and was unable to maintain normal driving speed. The sudden loss of propulsion created a safety risk because the vehicle could no longer operate normally in traffic. I was able to move the vehicle out of traffic, but it would not restart. I also observed white smoke coming from the engine compartment. The vehicle was towed to Matt Bowers Hyundai Slidell, an authorized Hyundai dealership, where it remains and is available for inspection upon request. The dealership has inspected the vehicle and advised that the engine needs to be replaced. The exact internal component that failed and the final cause of the engine failure remain under review by Hyundai. I do not recall any warning lamps or messages before the sudden failure. The timing of any prior symptoms is UNKNOWN. The vehicle had been maintained through authorized Hyundai dealerships. On December 29, 2025, a Hyundai dealership replaced the oil filter housing because of an oil leak and performed a synthetic oil and oil filter change. On March 11, 2026, approximately five weeks before the failure, the dealership performed another oil and oil-filter change and a multipoint inspection. I am reporting this incident because the sudden loss of engine power while driving, the inability to restart, and the smoke from the engine compartment created a serious safety concern. The vehicle remains disabled and available for further inspection.

I own a 2022 Hyundai Palisade SEL. On XXX, while driving at the intersection of [XXX] and [XXX] in [XXX], the engine abruptly lost power, causing a sudden loss of engine power while the vehicle was in motion. This is my family's primary vehicle, and my wife and children were in the car during this incident. On XXX, I brought the vehicle to Courtesy Hyundai in [XXX]. The dealer found essentially no oil in the engine despite my keeping up with scheduled oil changes. The dealer replaced the oil and performed a software update described on the repair order as "9C9 C ECU SW UPDATE EMISSIONS IMPRV 26-01-010H," and I was instructed to return after 1,000 miles for an oil-level recheck. At that recheck, the dealer's service assistant reported the oil was full. On XXX, before a planned family road trip, I returned the vehicle for another check. The service department found the engine was two quarts low — this was only 4,000 miles after the oil service on April 10, 2026. The dealer stated they requested an oil consumption test but that Hyundai denied the request. Per the dealer's instructions, I returned again after another 1,000 miles, and the engine was one quart low. I am filing this complaint because I believe the excessive oil consumption and the resulting loss of engine power represent a safety defect that has not been remedied. An engine that abruptly loses power while driving creates a serious hazard, including loss of power steering and reduced braking assist, and I am concerned for my family's safety while this condition remains unresolved.

While driving at normal speed, my 2022 Hyundai Palisade suddenly lost power without warning. Multiple warning icons appeared on the dashboard at the same time. The vehicle immediately slowed down and became unsafe to operate. After pulling over, the vehicle would not restart and had to be towed. This created a dangerous situation on the roadway. I am reporting this because I wonder if other owners may have experienced similar sudden power-loss events with this model year. It was fortunate that I was on a secondary road and not on the highway when this happened because it could have resulted in fatalities.

The first incident, my SUV failed to start, per Roadside Assistance, I replaced the battery. No diagnostic testing done. On 12/26/25 my SUV STOPPED COLD while driving. Red battery light and other warning indicators on dashboard lit up. Radio went dead; loss of steering assist; loss of vehicle power; dashboard went black and SUV SHUT DOWN. It would not start again. Towed to Hyundai for diagnostic test. I leave my home at 4:30 a.m. every morning driving 30 miles on the beltway to work. Imagine the danger, Stopping Cold on the beltway, in the dark alone with no power for emergency lights to warn approaching traffic of the danger. I travel with my family in my SUV on the beltway daily. I no longer trust this vehicle, and I’ve requested to be reimbursed; my vehicle is my livelihood and it’s my life and the lives of my family each day that I get into this SUV. SUV is paid off. Rockville Hyundai’s finding was a faulty alternator and battery. The original battery was in the SUV with the first incident, still I’m terrified to drive this SUV. I researched possible causes for my SUV performing in this manner and my research yielded, and I quote: “Electronic troubles with the 2022 Palisade Calligraphy often involve dashboard warning lights, driver-assist malfunctions, instrument cluster failures, and even engine shutdowns, frequently linked to issues like a faulty alternator, low battery voltage, or problems with the instrument cluster itself (Recalls), with some owners reporting dangerous situations like loss of steering assist or vehicle power loss on the highway.” On 1/6/26 on the beltway, the battery light and other warning indicators lit up; radio went dead, all warning indicators on the dashboard lit up; experienced loss of steering assist; and the dashboard went black instantly. I reached home, and parked; lights on the dashboard came back on, and I turned the engine off. On 1/7/26 I drove to Hyundai for another diagnostic test. 1/21/26 SUV still in service.

While driving, the vehicle intermittently loses engine power without warning. The loss of power occurs at normal driving speeds and during acceleration, creating an unsafe condition in traffic. When the issue occurs, the vehicle hesitates and fails to respond to throttle input, making it unsafe to merge or maintain speed. The condition occurs intermittently and does not consistently trigger warning lights or diagnostic trouble codes. Despite the absence of warning lights or stored codes, the loss of power is clearly felt while driving and presents a serious safety concern. The issue has occurred multiple times and has not been permanently resolved despite prior service visits. The intermittent nature of the failure and lack of codes makes diagnosis difficult, but the problem continues to recur and affects the safe operation of the vehicle. This loss of power creates a risk of stalling or sudden deceleration while driving, increasing the likelihood of a collision, especially in traffic or at intersections. The issue appears related to the engine timing or powertrain system.
