Hyundai Palisade hesitation problems

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.

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.

The engine misfires and runs very rough when stopped in drive after highway driving, and the vehicle hesitates and struggles to accelerate from a stop. At about 3,000 miles, Phil Long, Colorado Springs diagnosed a failing cylinder 6 fuel injector and replaced it on 22 April 2025. The problem continues after that repair. The condition repeats in the same way. After 15 minutes to 1 hour of interstate driving, I exit the highway. When I stop at the first traffic light on the off ramp, the engine begins idling very rough, and the tachometer shows about 500 RPM. When I shift to park, the idle smooths out. When I shift back to drive, it becomes very rough again. Pulling away from the light is difficult because the vehicle hesitates and does not accelerate normally. This has happened three times since the repair, most recently on [XXX] at about 5,800 miles. The check engine light did not come on. Conditions: 80 F, clear weather. [XXX] exit [XXX]. This is a safety concern because the vehicle may not accelerate when I pull into an intersection or merge into traffic. Other 2026 Palisade owners have reported similar misfires and hesitation, and Hyundai issued TSB 26-01-068H (Service Campaign 9D6) for engine misfires on 2026 Palisade 3.5L vehicles. I have asked Hyundai to confirm whether this campaign has been performed on my vehicle. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On August 10, 2026, at approximately 12,302 miles, I took the vehicle to an authorized Hyundai dealer after it stalled multiple times, including once while accelerating. I also reported sluggishness/loss of power. The dealer was unable to duplicate the problem. The vehicle subsequently stalled two additional times. In September 2026, while driving at highway speed with cruise control engaged, the vehicle suddenly and aggressively decelerated/braked as though it detected an obstacle ahead, although no vehicle or obstacle was present. A similar event occurred the following day. Unexpected braking, loss of power, or stalling at highway speed creates a serious collision risk. I have also experienced a forward-collision warning when no vehicle was in front of me and intermittent jerking/hesitation. I returned the vehicle to the Hyundai dealer on September 22, 2026, at approximately 14,548 miles. The dealer performed diagnostic scans and approximately 42 miles of road testing. No relevant DTCs were found, the problems could not be reproduced, and no repair was performed. The dealer documented the result as No Trouble Found. There were no consistent warning lamps or messages before the stalling or unexpected deceleration. The cause remains unresolved despite multiple dealer visits.

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.

While traveling along a high-speed highway, our 2026 Palisade unexpectedly suffered a severe loss of acceleration. Despite fully depressing the accelerator pedal, the vehicle struggled to exceed approximately 20 miles per hour. This alarming malfunction placed us in a precarious and potentially dangerous situation, as the drastic reduction in speed exposed us to the risk of being rear-ended by faster-moving traffic. On a separate occasion, the vehicle again exhibited troubling behavior, failing to respond appropriately while merging onto the highway. This hesitation significantly compromised our ability to safely enter the flow of traffic and could have easily resulted in a collision. Disturbingly, in both incidents, the vehicle provided no warning indicators or alerts on the dashboard, leaving us without any guidance or explanation for these critical failures.

2020 Hyundai Palisade, VIN: [XXX] . Excessive engine oil consumption beginning at ~95,418 miles. Oil drops to critical levels between oil changes, causing engine hesitation, rough running, and Check Engine Light activation — CEL clears only after oil is manually added, confirming oil starvation as the cause. SAFETY RISKS: Engine seizure or stall at highway speed; engine fire from oil burning on hot components; sudden loss of vehicle control; CEL only illuminates after oil is already critical, leaving no safe warning window. DEALER: Vehicle brought to dealership in [XXX] on 8/25/25 (95,451 mi) and Barnes Crossing Hyundai, [XXX] on 4/22/26 (99,969 mi). RO# XXX/1. HMA Case# XXX. Both dealers confirmed abnormal oil consumption. MANUFACTURER RESPONSE: Hyundai Motor America denied all repair or engine replacement solely because the title was transferred from a family member. Hyundai's own XXX (Dec. 2023) acknowledges systemic oil consumption across all Hyundai gasoline engines and mandates a repair protocol including engine replacement. A title transfer does not cause a mechanical defect and Hyundai failed to apply its own TSB procedures before denial. REQUESTED ACTION: Investigate HMA's pattern of denying TXXX remedies after title transfers; compel engine repair/replacement at no cost; evaluate safety recall eligibility.

I recently purchased this vehicle, and shortly after, it began having serious powertrain issues. When I accelerate, the vehicle intermittently loses power and starts shaking violently. It feels like the engine or transmission is slipping or failing. The RPMs surge and drop rapidly, and the vehicle hesitates, jerks, and sometimes briefly slows down before suddenly accelerating again. This creates an unsafe and unpredictable driving condition, especially when merging or driving in traffic. I’m concerned about a loss of propulsion while the vehicle is in motion. My mechanic indicated the issue may involve the torque converter clutch not engaging properly (possible “stuck off” or circuit performance issue), which would explain the shuddering and inconsistent power transfer. Despite how severe this is, there are no warning lights or check engine light, and no diagnostic codes, which raises concern that the failure is not being detected by the vehicle’s onboard systems. I am also experiencing low and fluctuating engine oil levels even after topping it off and a recent oil change, which may indicate an additional engine-related defect. The vehicle has a clean title and no accident history. - Failed system: Powertrain (engine/transmission), suspected torque converter clutch malfunction. Vehicle is available for inspection. - Safety risk: Intermittent loss of power, hesitation, and surging creates a high risk of collision, especially in traffic or at highway speeds. - Confirmation: My independent mechanic has identified as likely a torque converter related issue. - Inspection status: Not yet inspected by manufacturer or insurance. - Warnings/symptoms: No warning lights or codes. Symptoms began shortly after I purchased and have worsened over time.
