2020 Hyundai Palisade

Dear NHTSA, I'm reporting a serious safety issue with my 2020 Hyundai Palisade (3.8L V6) involving excessive oil consumption without low-oil warning lights. Timeline: Oil changed: August 13, 2025 → Engine stalling/rough idle → Checked Oct 27, 2025: completely out of oil Oil changed again: October 27, 2025 → Same symptoms recur → January 16, 2026: completely out of oil again Usage: ~300 miles/week (1,200 miles/4 months) using full synthetic 5W-30—far below Hyundai's 7,500-10,000 mile interval. Safety Risk: No low oil warning despite total depletion x2, risking catastrophic engine failure while driving. Known Lambda II V6 issue per TSB 20-01-0001. Request: Investigation into oil consumption recall and sensor failure.

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.

Check engine light came on and stayed on. When using heat for car it was not heating up well or to temp. Got in to be serviced 12/16/25-12/18/25. Replaced a plastic part in engine and said engine was not heating up like it should. Cost $814. Reset check engine light. On 1/2/26 reversed car out of driveway into street and car came to abrupt stop and would not shift into any other gears. Another vehicle was coming up the street and almost collided with us and I could not get my vehicle to move which was blocking the road. Warning message said “Shifter System Malfunction: Service Immediately.” Pushed power button to turn off vehicle. Turned back on and able to get into drive to park back in driveway. Definitely having electrical issues and multiple problems with car since October 2025 when weather became colder for winter.

The instrument cluster seems to fail more so in the hotter weather. The speedometer, RPMs and gas gauge just stop working altogether. This seems extremely similar to the issues of other Hyundai vehicles that were recalled. The blind spot monitoring turns on and off as it pleases and there is a message that comes up sometimes that say it has been turned off due to electrical failure. The HDMI port in the counsel does not work but half the time so using android auto fails constantly. The radio signal is very poor in the car, resulting in static and high pitched noises on the stations and cannot use regular stations. There also is a huge oil consumption and oil burn smell and leak. This also seems very common for other Hyundai vehicles that have been recalled. Having to put 4-5 quarts in per month and only drive it maybe 1,500 miles in that time frame. There is a pause bumpiness when having to accelerate sometimes as well, followed by failure of oxygen sensor smells and baffles within the muffler seem to often have weird sounds. Have had the vehicle for 1 year and it was bought as a Hyundai certified pre-owned vehicle. It only has about 85K miles on it.

On July fourth, while driving, the vehicle began to shake and make a rattling noise, shifted into park, and the dashboard lights lit up. While attempting to reach the safe side of the road while driving downhill on a busy road, the car lost power. I was able to pull over, restart the car, and reach a safe destination. I took the vehicle to the mechanic, who initially said I needed new tires, so all four tires were replaced. Three days later, the incident with the car shifting and losing power occurred again. The second time, I took it to the Hyundai dealership, which determined that only an oil change was needed, although I had completed regular maintenance on the vehicle. In November, the vehicle began shaking again and lost power while in motion. Again, the vehicle was taken to the Hyundai dealership, which stated that there were possible issues with the oil consumption.

Twice the engine oil consumption was bone dry. No warning lights or oil leaks on the driveway were seen. The engine without oil was subject to destruction . We replaced the oil twice - with documentation . Oil changes were made within 6 months since we purchased the car ( documentation was given ). It is known that specific models were affected by a bad engine that was installed ! Hyundai has offered nothing but aggravation even though it is known that there is a problem with specific engines that were put into the 2020 Hyundai palisade .

Engine started burning oil at around 70,000 miles. It now runs almost completely out of oil at around 5,000 miles since last oil change, not even close to reaching the manufacturer recommended interval of 7500 miles between oil changes. On top of the engine consuming oil at an alarming rate, there are no warning indicator lights that turn on to let you know your oil level is critically low. At around 74,000 miles?, Hyundai did a combustion cleaning. I've had two oil changes and it was back to vibrating, knocking, shifting hard, etc, right before a 3rd one at 5,300 miles since the last one and it stalled. The vehicle has now stalled twice, all engine lights flashed, then car stalled. Thankfully, this was not on an interstate or major road. This is a major problem!
