2020 Hyundai Santa Fe — Known Issues & Recalls

Your engine has experienced severe internal damage with burnt valves, which the owner attributes to a known defect with how the piston rings were installed in this engine model. This type of failure typically results in the engine no longer running properly. Repair will likely require professional engine rebuilding or replacement to address the damaged valves and piston rings.

Your engine has been consuming oil excessively since purchase, and the problem worsened after 100,000 miles. Around 100k miles, the car suddenly wouldn't accelerate past 35 mph on the highway. A dealer inspection found the engine and turbocharger need replacement. The fix will likely require a complete engine and turbocharger replacement under warranty or at dealer service.

Your engine has a leaking valve cover gasket that's allowing fuel to enter the engine oil and damaging spark plugs, ignition coils, and fuel injectors. The high pressure fuel pump and fuel injectors are spraying fuel directly into the engine and oil pan instead of into the combustion chamber. You may notice a large amount of fuel in your oil when you change it. Fixing this will require replacing the valve cover gasket, fuel pump, fuel injectors, and likely the spark plugs and ignition coils.

Your engine is burning through oil faster than normal, with oil leaking into the cylinders and causing heat damage to the engine components. This excessive oil consumption could eventually lead to engine failure if not addressed.

Your engine's oil drain plug seal is leaking, and even when tightened to the proper specifications, it continues to leak. This causes oil to drip from your engine and could lead to low oil levels if not addressed. The fix will likely involve replacing the drain plug seal and possibly the drain plug itself.

After 110,000 miles, your engine started consuming oil noticeably and developed a knocking sound. According to the complaint history, these Theta II GDI engines (2.0L and 2.4L) from Hyundai/Kia have a pattern of developing these issues that can eventually lead to engine failure. The owner is requesting a recall and engine replacement.

Your engine is burning through oil much faster than normal. You're seeing the low oil warning light come on repeatedly, and you've had to add oil multiple times between oil changes—sometimes adding 1-2 quarts within just a few hundred miles of driving. This problem started happening recently over the last few months. The issue may involve worn piston rings, valve seals, or other internal engine components that need inspection and possible replacement.

Your engine shut off while driving after about 1.5 hours on the road, and smoke filled the cabin when you tried to restart it. An oil leak had occurred during driving without any warning lights to alert you, which caused the engine to seize and fail. Your Hyundai dealer says the oil plug was improperly installed at your last oil change, resulting in over $10,000 in engine damage, but they're denying warranty coverage as a service issue while Jiffy Lube denies responsibility. Resolving this will likely require investigation into the oil change service performed and potentially engine replacement or major repair.

Your car suddenly lost power and could only drive 45 mph. The dealer found excessive oil consumption and carbon buildup in the engine, and discovered a faulty exhaust valve. Your warranty claim has been delayed over a month while the dealer and warranty company investigate whether the damage is covered, even though your lifetime powertrain warranty should cover the exhaust valve. The repair will likely involve engine teardown and replacement of the faulty valve or entire engine assembly.

Your check engine light keeps coming on with a P07410 code, and this has happened multiple times. The Hyundai dealer has cleared the code several times but says they can't find anything wrong, though once it cleared itself after 50 miles of driving. You're unsure what's causing it, but the problem keeps returning.

Your rearview camera isn't working — when you put the car in reverse, no image appears on the display. Previously the image was distorted or frozen, but now it's stopped completely. This is a safety concern since you rely on the camera to see behind you while backing up. The fix will likely involve diagnosing the camera connection or wiring, and possibly replacing the camera unit itself.

Your sunroof suddenly shattered into pieces while you were driving on the highway, with no warning signs or prior impact. The collision center found an issue with the glass rack assembly, which your insurance company deemed too costly to cover. Both your insurance company and Hyundai's dealership inspections were unable to resolve the problem, and your vehicle has remained out of service since the incident. Resolving this issue will likely require replacement of the sunroof glass panel and inspection or replacement of the sunroof frame and mounting hardware.

Your engine suddenly stopped working while you were driving downhill, which immediately disabled your power steering and power brakes. Without these critical systems, you couldn't slow down or steer the vehicle properly and had to run through a school bus's flashing lights to avoid a collision. The dealership confirmed the engine had failed completely.

Your sunroof suddenly shattered and broke outward while your wife was driving at highway speeds (60 MPH). Despite the sunroof failure, she was able to safely drive the vehicle home. The sunroof will likely need to be replaced, which typically involves removing the damaged glass panel and installing a new sunroof assembly.

Your panoramic sunroof's front glass panel spontaneously shattered while your vehicle was parked, making a loud noise. The dealership confirmed this is a known issue with this sunroof model but won't cover it under warranty. If this had happened while you were driving with the sunroof open, glass pieces could have created a serious safety hazard. The repair will likely involve complete sunroof panel replacement.

Shortly after purchasing your vehicle, your check engine light started flashing and your car lost power while driving on a highway in heavy rain. Your vehicle displayed error code P1326, which relates to engine and wiring harness issues. The problem forced you to pull over safely, but this could have been dangerous in heavy traffic. Diagnosing and repairing the wiring harness or related engine components will likely be needed.

Your panoramic sunroof roof panel shattered while you were driving on the highway, making a loud noise like a gunshot. The dealership suggested it was caused by road debris, but you note that many other 2020 Santa Fe owners have reported the same issue and a similar recall exists for 2016 models. Fixing this issue will likely require the sunroof panel to be replaced by the manufacturer.

Your 2020 Hyundai Santa Fe is experiencing gasoline fumes entering the cabin at low speeds, trouble starting in cold weather, and hesitation during hard acceleration. Your check engine light came on, and the dealer found a faulty fuel pump and high-pressure hoses as the cause—at only 49,100 miles. The repair is estimated at over $1,800. Fixing this will require replacing the fuel pump and high-pressure fuel hoses.

Your transmission is shifting roughly and shuddering during gear changes. The check engine light is coming on, and your dealership performed a software update that didn't fix the problem. The dealership is now recommending a complete transmission replacement to resolve the issue.

Your engine is consuming excessive amounts of oil between service intervals, and the dealership says this is normal wear. The engine has also started stalling unexpectedly. The dealer may need to inspect the engine for internal wear, leaks, or valve seal problems that could be causing the oil loss and stalling issues.
