2020 Hyundai Palisade problems

Filed Nov 9, 2026 · Transmission · GA

When turning at low speeds, the rear wheels feel like they're binidng, kind of like old school posi-traction. I took it into Grand Hyundai of [XXX]. The first time they told me it was a battery issue since it an electrically controlled power train. I replaced the battery somewhere else that was 1/2 the price. I brought the car back when I continued to have issues, they told me it was a bad battery. I informed them I replaced the battery to which they told me it was the battery still. I have no resolution on this. I understand there was a TSB associated with a similar issue on SOME VINs, but apparently not mine? It's Hyundai TSB 26-TC-001H.

Windshield has cracked multiple times

Filed Oct 9, 2026 · Steering · WA

On three separate occasions, when turning left, the steering wheel locked briefly at the 11pm position and there was a clunking noise. It released after a second or two. Obviously having steering lock is a severe safety issue. I have had it at Haselwood Hyundia in Bremerton, WA for a week and because they cannot reproduce the issue themselves, they are sending me home with the car unfixed. There were no warnings or other notifications and apparently no diagnostic codes.

My 2020 Hyundai Palisade experienced repeated instances of the engine cooling fan continuing to operate after the vehicle was completely shut off. In one instance, the fan ran for about 90 minutes after shutdown. After the vehicle was driven again, it ran for approximately another 45 minutes after shutdown. On a subsequent occurrence, the fan continued running until it discharged the battery enough that the vehicle would not start. Southtowne Hyundai in Newnan, Georgia subsequently diagnosed the cause as an internal PCB block failure and replaced the engine-room PCB block pursuant to Hyundai Technical Service Bulletin 26-EE-007H, which addresses battery drain caused by continuous cooling-fan operation after the vehicle is turned off. The dealer installed PCB block part number 91959-S8000-FFF. The failure was intermittent and did not occur every time the vehicle was shut off. My concern is that the defect could unexpectedly discharge the battery while the vehicle is parked, leaving it unable to restart. I am filing this complaint so the federal safety agency has a record of the failure and can determine whether similar failures are occurring in other Hyundai Palisades.

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.

There is pre-mature failure of the rear shocks/struts. Vehicle is a 2020 Hyundai Palisade Limited with 70,000 miles on it. Normal wear and tear with no excessive use and never towed anything. Hyundai dealerships are backed up for service appointments. I was finally able to get in for an appointment, and they confirmed pre-mature shocks/struts failure but parts are on back order. The dealership states the vehicle is "safe to drive" but I am concerned. We are a family of [XXX] and are worried about a bad outcome with all the extra bounce in the car on [XXX].

My 2020 Hyundai Palisade (3.8L V6) has a persistent engine defect causing sudden stalling and severe oil consumption. Since mid-2019 the engine has stalled without warning when coming to a stop, idled roughly, and made loud puttering noises under light acceleration — a loss-of-power hazard in traffic. In 2026 the dealer began formal oil consumption testing. Although 1,000-mile checks were marked 'passed,' the engine was found completely dry (dipstick showed no oil) at 2,000 miles — 3.5 quarts low on a 6.1-quart system. On 09/02/2026 the vehicle FAILED an official oil consumption test at Hyundai of Kirkland and was held for service. The dealer performed a carbon-cleaning procedure, but the underlying oil consumption is unresolved and a re-test is now underway. Running an engine at less than half its oil capacity risks sudden seizure or stall at speed. I am concerned this is a systemic defect affecting other 2020 Palisades and request the federal safety agency investigate.

Defect & Safety Hazard: Severe internal manufacturing defect causing catastrophic engine oil consumption and sudden, un-warned engine stalling. The vehicle completely shuts down at highway speeds, on inclines, and at stops. This sudden loss of motive power deactivates power steering and braking assists, creating an immediate multi-vehicle collision risk. No low-oil or dashboard indicators illuminate prior to stalling, stripping the driver of any ability to take proactive safety measures. Indisputable Failure Data: Between 99,xxx miles (under warranty) and 103,xxx miles, the engine consumed 5.5 quarts of oil over a 3,000-mile interval. This equals an extreme burn rate of 1.83 quarts per 1,000 miles. Hyundai’s maximum corporate failure limit (1.0 qt/1,000 miles). Secondary diagnostics indicate this massive volume of un-combusted oil is actively pushing into the exhaust system, creating restrictive backpressure that induces stalling. Timeline & Dealer Obstruction:Rusty Wallace Hyundai: Inspected vehicle under 100,000 miles and initiated the first 1,000-mile consumption test, but subsequently refused documentation and further warranty services. A corporate national claim and customer service complaint were filed against them.Grayson Hyundai: Completed a second 1,000-mile test documenting a definitive failure. They confirmed this is a common, known systemic issue and recommended full engine replacement.Federal Violations: Under the Magnuson-Moss Warranty Act, because the defect was reported to a dealer before warranty expiration, Hyundai is legally required to cover the defect. Forcing a vehicle that burns 5.5 quarts of oil onto public roads also violates strict EPA Clean Air Act emissions compliance standards. Hyundai's current demand for out-of-pocket payment must be rescinded for full corporate coverage.

I am reporting severe and recurring oil consumption in my 2020 Hyundai Palisade that could cause engine damage, engine seizure, stalling, or a sudden loss of power while driving. On April 14, 2026, at approximately 89,950 miles, an authorized Hyundai dealership documented that the engine had consumed approximately 1.3 quarts of oil in only 1,275 miles, equivalent to approximately one quart every 982 miles. The vehicle failed Hyundai’s initial oil-consumption test. Hyundai then authorized a combustion-chamber cleaning. On May 12, 2026, at 91,087 miles, the dealership completed the follow-up test and stated that the vehicle passed at that time. On September 14, 2026, at 95,512 miles, I returned to the dealership because the engine again had no measurable oil remaining. Only 4,425 miles had elapsed since the May oil change. The dealership’s repair order states that the vehicle “has no oil again.” I also reported that the vehicle had begun stuttering and rattling when pressing the brake and coming to a stop, creating concern that the engine may already have sustained damage from insufficient lubrication. The dealership initiated another oil-consumption test and instructed me to return after 1,000 miles. However, the earlier combustion-chamber cleaning did not correct the underlying problem. I am concerned that the vehicle may again consume its oil without adequate warning and could stall, seize, or lose power while being driven, placing the occupants and other motorists at risk. Hyundai should investigate the cause of the recurring oil loss and determine whether 2020 Hyundai Palisade vehicles have defective piston rings, cylinders, valve components, PCV systems, or other engine components causing excessive oil consumption. I am requesting that the federal safety agency document and investigate this potentially dangerous engine defect.
