Hyundai Palisade jerking problems

Filed Oct 16, 2026 · Engine, Transmission · WA

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 1 year old vehicle experienced a serious transmission/drivetrain malfunction that ultimately made it unable to drive. On September 3, 2026, while I was on the road, the vehicle stopped operating properly and had to be towed to the Hyundai dealership. The vehicle and affected components remain available for inspection at the dealership. The failure created a safety risk because the vehicle became unreliable and inoperable while being used on public roads. A sudden loss of propulsion or inability to move normally could have placed me and other motorists at risk, especially in active traffic. The problem was reproduced and confirmed by the Hyundai dealership. After performing work, the dealer told me the vehicle was ready for pickup on September 4. However, the same issue was still present before I even left the dealership, so I left the vehicle there again. A few days later, when I returned to retrieve personal belongings, the service advisor said the vehicle could not be driven and we had to go to the rear parking area where it was stored. The vehicle has been inspected and serviced by an authorized Hyundai dealership, and Hyundai corporate has also been contacted regarding the issue. To my knowledge, it has not been inspected by police, insurance representatives, or an independent repair facility. Prior to the complete failure, the vehicle showed symptoms of improper transmission/drivetrain operation. The revolutions would spike when gas was applied and then lurch forward when it finally caught. The problem became severe enough on September 3 that I could no longer safely continue driving and required a tow. I do not recall a specific warning lamp or dashboard message and would rely on Hyundai’s diagnostic records for any stored fault codes or warnings.

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.

Driving less than 30 mph, the Forward Collision System enaged (there was nothing near the vehicle) and the vehicle suddenly jerked and braked pulling the car as if it was not in its lane.

I am reporting a potential safety defect involving my 2021 Hyundai Palisade Calligraphy AWD. The vehicle has experienced repeated engine and drivability problems and multiple breakdowns following replacement of the engine by Hyundai. The original engine developed excessive oil consumption and was ultimately replaced by Hyundai with a new engine. Following the engine replacement, the vehicle experienced numerous additional mechanical problems and repair attempts, including engine rattling/pinging, intake-manifold replacement, oil valve-seal replacement, multiple cylinder misfires, ignition-system problems and an ignition-coil failure. Most concerning are repeated incidents involving severe shaking/lurching, loss of engine power, stalling and failure to restart. During one incident following repairs, the vehicle ran extremely rough, stalled and would not restart after approximately 20 miles of driving and had to be towed back to the dealership. During another incident, the vehicle experienced heavy shaking on startup, stalled and had severely limited power. Diagnostic history showed misfires involving multiple cylinders. On June 29, 2026, at approximately 103,671 miles, I was driving at approximately 50 mph when the vehicle began to lurch and shake, lost power, stalled and would not restart. The vehicle had to be towed back to the Hyundai dealership. The unexpected loss of propulsion and stalling while traveling at approximately 50 mph created a serious safety concern because I could no longer rely upon the vehicle to maintain power in traffic. The dealership subsequently identified an ignition-coil short/failure and replaced an ignition coil. The vehicle has nevertheless continued to experience additional mechanical problems. The vehicle is currently again at the Hyundai dealership. It has generated diagnostic code P0430 for Bank 2 catalyst efficiency below threshold, and Hyundai has recommended replacement of both catalytic converter/manifold assemblies. Th

The vehicle brakes malfunctioned while driving over bumpy pavement in a parking lot. There was a loss of ability to stop the vehicle, the breaks seemed locked or ineffective. This cause me to come close to rear ending the vehicle in front of me. My foot was pushed FIRMLY on the break and the vehicle seemed to continue to lurch forward. The collision warning alarm was sounding and the brake pedal was vibrating.

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.

As I approached the traffic light from a parking lot, at slow speeds ie 5mph, I hit a patch of uneven ground where the concrete was uneven. The brakes stuttered and lurched. I pumped the brakes without much success and came within inches of hitting the car ahead of me. This has happened multiple times. Another time, I was approaching an intersection again at approximately 30 mph. The brakes stuttered so hard that I barely stopped before entering the path of the oncoming traffic. On a later separate time, traveling at approximately 35 mph, we were fully in the crosswalk when the car finally stopped. These were just the scariest of times, not inclusive of all occurrences. The trouble began within the first few months of purchasing the car in 2023 and still happens. I reported this to the dealership on several occasions. They claim it is normal for the vehicle but it is a danger to the occupants in the car and the nearby pedestrians.

The steering wheel clunks and locks when turning at low speeds or when ISG turns the car back on. At times, it is a hard enough jerk to pull it out of my hands. It was taken to the dealership multiple times. The coupler was replaced, but it still jerked the steering wheel. The dealership in Utah could not replicate the sound, even though it occurs multiple times a day at this point. Loss of the ability to steer after sitting at a light poses a huge safety issue between not being able to immediately navigate upon accelerating or when turning left at an intersection.
