2020 Hyundai Palisade: engine knocking or ticking

Filed Oct 5, 2026 · Engine · GA

My 2020 Hyundai Palisade (3.8L V6) suffered an engine failure at approximately 108,000 miles. On September 3rd,2026 , while driving at about 65 mph, the engine began knocking loudly. There was no warning before this happened and the engine light had not come on. The vehicle was taken to Shottenkirk Hyundai, an authorized Hyundai dealer, which diagnosed a connecting rod bearing failure. The repair order states: "Replace engine assembly due to piston slap on front bank caused by rod bearing failure." The dealer says the entire engine must be replaced. The vehicle has been maintained with regular oil changes. The failure was internal and was not caused by a crash, impact, or outside damage. I believe this is a safety defect. A connecting rod bearing failure can cause the engine to stall or seize without warning while driving, including at highway speed, creating a risk of a crash. A failed rod can also break through the engine block and leak oil onto hot engine parts, which is a fire risk. The vehicle is past Hyundai's 100,000-mile powertrain warranty. I have opened a case with Hyundai Consumer Affairs (case # 43347615) and am waiting for a decision. The vehicle and failed engine are available for inspection at the dealer. I am asking the federal safety agency to investigate connecting rod bearing failures in the 3.8L V6 engine in the 2020 Hyundai Palisade.

On August 14, 2026, while driving and decelerating, I heard a knocking sound from the engine and the vehicle had difficulty downshifting. As the transmission shifted from second gear to first, the engine stalled immediately and the vehicle dropped into neutral while on the roadway. I lost propulsion in traffic. The vehicle behind me nearly rear-ended us due to the sudden stall. My children were in the vehicle. All dashboard warning lights illuminated at the moment of the stall. I was able to restart the engine and move the vehicle slowly, in first gear only, into a nearby parking lot. The check engine light came on at that restart and has remained on since. The vehicle sat parked and off for approximately 90 minutes. Before restarting, I checked the engine oil level and it was within the normal range. On startup, my children and I both heard a loud knocking sound and noticed an unusual smell, and the engine idled roughly while in Park. I drove approximately 15 minutes home with the rough idle continuing. On arrival the vehicle smelled hot, with a burning odor, although the temperature gauge read approximately mid-scale and was not in the high range. The check engine light remained on and the oil level was again confirmed to be within range. The vehicle has been out of service since the incident and is currently at a dealership awaiting diagnosis. This is a 2020 Hyundai Palisade with approximately 93,000 miles at the time of failure. A sudden loss of motive power in a travel lane is a safety defect.

The vehicle continues to feel very bumpy when we drive. Even if I stand in the 2nd row and press up and down, it makes a squeaky, sometimes loud rattling / knocking sound. I have taken this to the dealer multiple times and they tired to tighten shock absorbers and the padding around it but the problem hasn't gone. They ask me to leave the car with them without getting a loaner which is hard to do as we need the car. They have made it hard to get the problem solved, not taking ownership and have denied any issue with the suspension despite multiple complaints by consumers in online forums and what i have personally experienced.

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!

I was driving through town at a low rate of speed (20-30 mph) with 2-3 car lengths between me and the next vehicle. I continued through light to next light. This distance was on an upward incline. After traveling approximately 500 ft, I noticed the traffic slowing in front of me and took my foot off the accelerator to start to slow down. This is when the car suddenly accelerated (instead of slowing down as would be expected when traveling up an incline), picking up speed quickly. The car's response happened so quickly that I was unable to swerve to avoid hitting the car in front of me. I hit the car in front of me that was slowing down at the light which then subsequently hit several other vehicles that were in front of it that were also slowing/stopped for the light. The front airbag deployed as a result of the collision, knocking my glasses off. The vehicle was still continuing in forward motion after the collision….Traffic Crash Report states, “... [witness] went up to Unit 1 [Palisade], and the tires were still spinning…” As I was in shock after the collision, a bystander came up to the vehicle to turn it off and this is when the wheels/forward motion was completely stopped. This Palisade is equipped with Forward Collision Avoidance Assist (FCA) system. There was no warning given nor did the vehicle attempt to slow down during the event so I believe that this system failed to operate which contributed to the collision. I also believe that there was a failure with the engine/electrical system, ETC, and/or transmission that caused the system to suddenly accelerate while traveling uphill AFTER I removed my foot from the gas pedal. The vehicle was totaled by my insurance company. They did say that they were sending an engineer to review the Event Data Recorder. I have not seen any results from that nor do I have the vehicle in my possession as it was totaled.

This vehicle has excessive oil consumption, and the low oil light does not light up to tell you that you are low on oil. I only noticed that I was low on oil because the engine starts knocking and started to stall. I had the oil changed according to all service intervals and at one point the dealership told me my car had no oil left in it. I just had it changed, drove about 2k miles and already had to put more oil in because it didn't even show any oil on the dip stick. This is a safety hazard as well as an environmental problem with these vehicles burning this much oil. This started happening around 80-90k miles on the engine.

Have a 2020 palisade unlimited with self leveling shocks, started hearing clunking, knocking noise in rear. Have 74k miles currently but started hearing knocking sound at about 55k miles. Replaced shock mounts on both sides which didn’t fix the problem.

2020 hyundai palisade limited with 71k miles. The rear shocks have been replaced 2x and the front struts have been replaced once already. The front struts knock over smooth rides and low impact imperfections. the rear shocks feel to have seemingly worn out, resulting in reverberating knocking sounds over bumps, cracks and road imperfections.

Rear shocks failing due premature wear and tear. There were/are no warning lamps and there was no singular incident (eg. accident) that caused this problem that I am aware. The passenger-side rear shock started exhibiting knocking noises in August 2024 when the car was 5 yo and had approx. 85000 miles. Since, the knocking is more frequent but not louder. Also, the ride has slowly become worse over bumps. Dealer confirmed problem.

Experienced complete engine failure. Car was at a Certified Hyundai dealership 2 weeks prior for new plugs and new coil pack. Multiple point inspection with no noted issues. Driving on a 3 hour trip when suddenly the engine started knocking without an engine light or oil light coming on. Pulled over and no oil on the dip stick. The same dealership did an oil change at 86,000 miles now the car has 92,000. No oil change suggested at last visit. Sounds very similar to other recall descriptions. Please review
