2020 Hyundai Palisade: shudder or vibration when accelerating

Filed May 26, 2026 · Engine · VA

The engine burns oil excessively and the oil light does NOT come on when the oil is low. Our car is right at 90k miles, it began to shudder and malfunction out of the blue while we were driving on the highway. There was absolutely no indication the oil was low. Now the car will not turn on at all. We were in between oil changes. The safety of myself and my family was put at risk because the engine blew with no warning. The vehicle has been serviced repeatedly by Hyundai for this issue, and they are trying to tell us that it is normal for oil to completely burn out in between oil changes.

The contact owns a 2020 Hyundai Palisade. The contact stated that he initially began to notice that his engine would consume oil at a rapid pace. As the failure persisted, the vehicle would shudder upon depression of the accelerator pedal as the check engine light appeared on the instrument panel. In addition, the contact stated that white smoke would emit from the exhaust pipe. The vehicle was taken to an independent mechanic where the spark plugs were replaced on two separate occasions due to carbon build up. The vehicle was then taken to a dealer where it remained in their possession for three months before the contact was informed that they were performing an oil consumption test. The contact was advised to bring the vehicle back at 1,000 to continue the oil test. After 1,000, the contact was informed that the engine showed no sign of excessive oil consumption. The contact then stated that while driving at 35 MPH, the vehicle shut off without warning as the contact managed to coast the vehicle into a nearby parking lot. The contact attempt to restart the vehicle; however, the engine failed to start. Due to the failure, the vehicle was towed to his independent mechanic where they diagnosed the vehicle with engine failure. The vehicle was then towed to another dealer(Diehl Hyundai of Sharon-1251 E State St, Sharon, PA 16146) where the vehicle remained in their possession for two months were they replaced the engine and vehicle starter. Upon return of vehicle while driving at 55 MPH, the front end of the vehicle began to violently shake and the contact immediately contacted the dealer. The contact was informed that the vehicle was not test driven before the vehicle was returned due to the excessive wear of the rear tires. Additionally, the contact stated that the steering wheel would shake while driving which would cause the contact to lose control of the vehicle without warning. The dealer refused to offer a loaner vehicle and that they would listen to the engine but could not guarantee any repairs. The contac

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.

Since about 90,000 miles I have noticed a shudder from my transmission. It has progressed and having transmission issues. I have had regular maintenance done on my car and have even replaced the transmission fluid twice and the shudder is continuing to happen. I have looked at forums and all the things and seems to be a common theme amongst their transmission style.

Vehicle is consuming or burning oil at a high rate. While dealer has done an oil consumption test and claimed it was "within tolerance," I have on multiple occasions had the car start to shudder at 2,000 miles since last oil change only to find the oil wasn't even on the stick anymore. The symptoms go away when adding oil, on some occasions more than 4 quarts of oil need to be added to get the oil to "full" on the dip stick. Multiple independent service centers have noted how dirty the oil is and how little is drained on oil change. No warning lights have come on at any time, even when car is making grinding noises and shuddering with no oil. This causes a safety issue as drivers reasonably expect to go at least 3,000 miles between oil changes and the engine could seize in traffic. Owners are being tacitly asked to add oil regularly to keep the engine functioning properly.

The GDI v6 motor that’s in it shudders and rattles when at idle. There’s metallic shavings and gas smell on the dipstick. It’s always low on oil and smokes a little at idle aswell. It’s completely ran out of oil and been to the shop 3x so far in a years time. Add oil to it every 2-3 weeks at this point ,It’s not leaking oil it’s definitely burning it. Once the dealership even had to come tow it to the shop the car shut off in the middle of the road and then again in the driveway as my wife was trying to turn into the driveway she lost all power and steering she ended up in the middle of the front yard, thank god she was just getting home at the time of the incident. I’ve heard of the same engine giving problems and having an open recall for similar issues pertaining to a bearing and or rings being damaged or broken allowing for the oil to be dripping or being burnt. The vehicle is a family vehicle and gets driven daily by my wife to and from the kids school and the grocery store it’s not driven hard or for very long periods of time. I would like to know if there’s anything that could be done about this issue. I’ve looked to see if the recall was open for this model palisade but it only shows for the Santife models even though it’s the same engine. The shop and dealers always tell me it’s nothing and just keep up with oil changes but that’s near impossible when it runs out of oil before the next oil change is due.
