2021 Hyundai Palisade: jerking or lurching

Filed Sep 1, 2026 · Electrical, Engine · IL

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 is experiencing a transmission failure that causes sudden jerking, hesitation, and loss of smooth acceleration when the engine reaches approximately 1,500–2,000 RPM. When driving under normal conditions on both city roads and highways, the transmission appears to slip or fail to properly engage or shift gears within this RPM range. When this occurs, the vehicle jerks violently and momentarily loses power, creating a dangerous driving situation. This happens while accelerating in traffic and when attempting to maintain speed. The sudden hesitation and loss of proper transmission engagement creates a serious safety concern because the vehicle may not respond properly to acceleration, increasing the risk of a rear-end collision or crash, especially when merging onto highways or driving in traffic. This issue occurs regularly and has become progressively worse over time, indicating a potential transmission defect rather than a one-time malfunction. The problem was inspected and documented by Bill Luke Marana dealership in Tucson, Arizona. During their inspection, diagnostic data showed abnormal transmission input and output speed readings, confirming irregular transmission operation. The dealership marked the concern as requiring immediate attention. There were no consistent warning lights prior to the failure, despite the severity of the symptoms. The vehicle and the dealership diagnostic documentation are available for inspection upon request.

The vehicle experienced premature transmission failure, including torque converter clutch malfunction, hesitation, jerking at speeds between 30–35 mph and 50–60 mph, and drivability issues. Diagnostic indicators are consistent with widespread complaints from other Hyundai Palisade owners. This failure presents a potential safety concern due to unpredictable vehicle response, hesitation during acceleration, and reduced control during highway driving. Dealer / Manufacturer Response: Hyundai Motor America requires an authorized dealer to submit a warranty or goodwill claim for review. The servicing dealer, Reliable Hyundai (Springfield, Missouri), has refused to submit the claim, preventing evaluation and resolution. This issue appears to be a known defect affecting multiple vehicles of the same model year. I am submitting this complaint to assist the federal safety agency in identifying patterns that may warrant investigation or recall action.

Auto-off reengaging makes the steering wheel jerk abruptly to the side and creates loud thinking noise which is startling to the driver. I was able to replicate at the dealer and have it on video. Dealer reports this is normal for the vehicle and they are unable to rectify.

On 01/12/24 my vehicle cut off while driving and wouldn't allow me to shift from park to shift. The transmission also had a habit of jerking back and forth when under load going up a hill. Hyundai dealership suggested a transmission flush. After the flush the problem came back in May of 2024

I've had several instances where the car didn't turn over and all technology screens began glitching, clicking and stating the key wasn't in the car. After a few tries, it would start up. Ice also experienced engine failure WHILE driving. The first time was at a stop light and the engine completely shut off and I had to park, and restart it. This has happened twice. When it did, all of the screens were glitching, flashing, lights came on/off, and then went black. The next time it happened, I was on the highway and it started to sputter, jerk (like it was running out of gas but I had over 1/4 tank).
