2020 HYUNDAI SANTA FE

I'm reporting a rearview camera issue in my Hyundai Santa Fe 2020. The camera image was previously static/distorted and has now completely stopped working. When the vehicle is placed in reverse, no image is displayed. This creates a safety risk, as the rearview camera is essential for visibility and preventing accidents while backing up. I am aware there has been a recall for similar rearview camera issues; however, my vehicle is not included because the recall is VIN-specific, despite experiencing the same problem.

The contact owns a 2020 Hyundai Santa Fe. The contact stated that while his wife was driving approximately 60 MPH, the sunroof shattered outward. The contact stated that his wife was able to drive the vehicle safely back to the residence. The vehicle had not been taken to a dealer nor an independent mechanic. The vehicle was not diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 72,000.

I was driving on the road and all of the sudden my car went limp and would only move 45 miles per hour. I took it to the dealer which I have lifetime powertran on my car. It has been there for over a month at the dealer. They asked me to provide all oil changes,services, and registrations. I did that and then fidelity asked them to tear down the engine again to see if I had carbon build up. Then after the dealer did that they ask the dealer to tear the motor down even further to see if the exhaust valve was bad and if it was bad they would not replace my motor. My car consumed so much oil that I was changing my oil so often. I have been renting a car just to get back and forth to work. In my contract it says that the exhaust valve is covered under my lifetime powertran. I feel like hyundai and fidelity are giving me the run around. I took very good care of my car and I have shown that. Hyundai has had alot of problem with there motors with the oil consumption and motors just going limp. I feel I will never buy a hyundai again. I am losing money everyday because of the dealer and fidelity. I need the motor replaced and it was no abuse on my part I took care of my car. I want fidelity to tell me how I abuse the exhaust valve. I did my oil changes and took care of my car. I am still paying on my Hyundai and can't afford another car. I have alot of medical bills that I pay. Any help would be great. Sincerely [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The front piece of the panoramic sunroof spontaneously shattered while sitting in my parked vehicle. I heard a loud pop and saw that the entire piece of glass was totally shattered. I took it to the dealership and they told me it is a known problem with this type of sunroof on their vehicles, they said it is not covered by warranty. The estimated repair cost was over $800. Had I been driving down the road with the sunroof open, it could have presented serious safety risks.

Our vehicle has encountered a catastrophic engine failure (burnt valves) due to a known and ongoing issue with the piston rings install in this engine.

On the morning of February 20 2026 at around 6:35am. I was on my way to work when the engine light started flashing and the speed started to decrease. I was traveling on a major highway in heavy rain with a lot of traffic. I had to put on my hazard lights and quickly pull off the road. The code given is P1326 which has to do with the engine and wiring harness. I just purchased the vehicle on Jan. 17 2026. The Carfax stated no open recalls.

The roof of my car between the sunroof and the windshield (called panoramic sunroof) shattered as I was driving down the highway. It was about 10:00 pm on a weeknight and there were no cars within sight distance in front of me. When it happened it sounded like a gun shot going off at point blank range and I immediately pulled over and checked for bullet holes. Since it was dark I could not see any damage. Today I took the car and had a small chip fixed in my windshield down by the windshield wipers and the service tech pointed out to me that the roof was shattered. He told me that this happens a lot with this vehicle. So I got online and searched and found a lot of vehicles have reported the exact problem. Down to the sounds of gunshots. So I stopped at my local Hyundai dealership and recorded the conversation. He told me that theres no recalls on this car and It probably shattered by a rock or debris. I told him that when this happened it was late night and no cars within sight in front of me. He didn’t even come out and look at the damage. He said to call my insurance company and I said that is a manufacturer defect and I shouldn’t have to pay for their mistake. When I searched for this on the internet people stated that the dealerships will deny this manufacturer defect and that’s exactly what they said to me. My main concern is that this defect is documented by many vehicle owners from their 2020 vehicles and their Is a recall out for this problem but it stops at 2016 models. In this recall the shattered piece is replaced and there is actually compensation given for people getting scared or dealing with stress dealing with thinking they are getting shot at. I don’t care about any of that. I just want the issue fixed because I did not cause the issue, the manufacturer did. Reason being is that the exact thing is happening to numerous people across the Country. Thank you for your time.

On the morning of December 10, 2025, I left my home for an appointment. I traveled for about 15 minutes before entering onto the highway. As I entered the highway, I traveled about half a mile and was scared by a very loud explosion! I pulled over to assess my vehicle and the surrounding area. The sunroof had SHATTERED to pieces, fortunately I didn’t have it open at the time. It was just a miracle I didn’t have an accident from being startled, or receive any cuts or injuries due to this unforeseen event. As I was driving, there was very little to no traffic and I never heard anything like hit the car or window or anything. I called my insurance company and filed a claim. They eventually had me to take it to a Collision Center 12/22/2025. They removed all glass from sunroof, and determined that there was an issue with the glass rack, and it would end up being very costly. My Insurance Provider contacted me to say they would not be able to provide coverage due to the cost and findings of the Collision Center. So they backed out and informed me that I needed to file a claim with Hyundai. So I picked the vehicle up 1/19/2026 from the Collision Center. Then I filed a claim with Hyundai, and was told to schedule an appointment for inspection. I took the vehicle for inspection 1/22/2026, after about a week I was told that the vehicle had been inspected there was nothing they could do. I’m confused as to how the inspection went since there was no glass present in order to check the opening and closing of the car rack. Plus the plastic that the Collision Center placed on it was barely removed. So I picked the vehicle up 1/30/2026. and it’s been sitting in my driveway covered every since. The vehicle has been inspected by a Collision Center, and the Dealership without any success. There were no warning lights of any indication of trouble on the dashboard at any given time, not even when the explosion occurred. The vehicle is available for inspection upon request. Thank you

While driving, the engine catastrophically failed without warning, causing an immediate loss of power-assisted braking and steering. The failure occurred while traveling downhill. I was unable to slow or control the vehicle properly and was forced to proceed through a school bus’s flashing lights to avoid a potentially catastrophic collision, resulting in a traffic citation. My son was in the vehicle at the time. A sudden loss of engine power, braking assist, and steering assist while driving presents a serious safety defect. Vehicle was towed to Fred Beans Hyundai in Doylestown where it has been confirmed engine failure. This failure happened immediately and without warning.

Excessive oil burn off. Oil is getting into the cylinder, causing scorching. This causing engine failure.

Oil drain plug seal leaking, can’t tighten the bolt with the required torque setting to keep it from leaking.

After 110,000, the engine started using oil and it began to knock. According to the history of these engines, it will lead to engine failure. They have a record of being a lemon engine and there is not a engine of this type that this does not happen. The engine needs to recalled and replaced, They are the Theda II GDI series of 2.0L and 2.4L four-cylinder engines from Hyundai/Kia.

I have a 2020 Hyundai Santa Fe, 2.0T. I recently experienced the following issues; gasoline fumes coming into the car at low speeds, difficulty starting the car when it is cold and hesitation when trying to accelerate quickly. The check engine light came on and the dealer diagnosed a faulty fuel pump and high pressure hoses......on a car with only 49100 miles! The repair cars are estimated at over $1800. This is totally unacceptable and there should be a manufacturer issued recall on the car where Hyundai covers the cost of the repairs.

Transmission issues with DTC light coming on, dealership did software update which did not resolve the problem. Transmission has rough shift and shuddering. Dealership is recommending complete transmission replacement.

2020 Hyundai SantaFe Limited AWD ... burning excessive oil. This only was noticed because the low oil light intermittently started coming on, and has only started happening in the last few months. low oil indicator flashing - 4QT low, went for an immediate oil change 78788 miles - oil changed 80252 miles - low oil - added 1QT 80628 miles - low oil - added 1QT 81376 miles - oil changed 81999 miles - low oil - added 1QT 82755 miles - low oil - added 2QT These are the most recent events since we started logging it.

2020 SantaFe Limited AWD with ~81200 miles. This is the 3rd or 4th time the P07410 code pops up with the Engine Check light. Hyundai said they found no issues and cleared the code, again. There was once when the code came up and it cleared itself after 50 miles. Not sure exactly what the cause is and Hyundai is saying "there is nothing wrong". Most recent occurrence Sept.4.2025.

My engine has been sucking up oil since the day I bought it. Once I hit 100k miles it started sucking up oil faster than the recommended oil changes. I was driving home two weeks ago. I went to get in a major highway and she would not go past 35 mph. I went to trade it in and was told it needs a new engine and a new turbo. This is a known problem and Hyundai will not fix it. This car is not even 4 years old. I got it in April 2021

I had been driving about 1.5 hours when I exited the Interstate and the car engine shut off at a traffic light. When I shifted the car into park and tried to restart the car, smoke filled the cabin. Unbeknownst to me, an oil leak occurred while driving. No warning lights or other indicators that anything was awry. I had the vehicle towed to the nearest Hyundai dealer. Though the suv is under warranty, they say the oil leak was caused by improper oil plug installation at the last oil change. The oil leak caused the motor to seize and the resulting damage is in excess of $10,000. Hyundai says the warranty won't cover this as it is a service issue. Jiffy Lube says their technician did nothing incorrect and they won't take responsibility for the repairs.

Excessive oil consumption. Mechanic who changed oil said oil level was too low and he could find no leaks. He said this is a known Hyundai problem. The dealer acknowledged this. There was no warning light saying the oil was low. It was discovered during a routine oil change.

I had my oil changed at a reputable service center November 19, 2025 and the mechanic said my oil drip pan and plug needed to be replaced in the next few months because they were showing wear and could fail. He asked if I knew about a pending lawsuit against Hyundai concerning these items causing major issues. I said I was unaware, so I researched it. It seems to be legit. During my research there were multiple reports that many had oil leaking problems and some owners reported that the vehicle completely stopped running. That is especially dangerous driving on an Interstate. I was quoted about $350.00 to replace the pan and plug but I was told to contact the local dealership to see if they would replace it. They wanted $215.00 for a diagnostic plus parts and labor. That is quite a chunk of money for a drip pan and plug.

The contact owned a 2020 Hyundai Santa Fe. The contact stated that while driving 40 MPH onto the ramp, the vehicle failed to accelerate as intended while depressing the accelerator pedal. The contact was able to pull over to the side of the road. The vehicle stalled and shut off, and the contact was unable to restart the vehicle. The contact was calling for Roadside Assistance and noticed white smoke coming from under the hood. The stated that the smoke then turned dark brown and then black, and then flames appeared under the hood. The contact grabbed several things of value and exited the vehicle and started running.

Unknown Sometimes when i stop the vehicle the engine shuts off and wont come back on until i put the car in park and turn the ignition off. Not safe at all when your in heavy traffic

White pearl paint is chipping off from the vehicle by itself without any outside force. This is outbreaks over all Hyundai white pearl paint vics and they are not account for their defect. This problem eventually cause erosion on the body of the vehicle and treat safety of the drivers and people around it. This seems common issue with my research, please look close into this problem and protect driver and customer who have no power to defend their right.

The contact owns a 2020 Hyundai Santa Fe. The contact stated that while driving approximately 40 MPH, the vehicle started shaking and lost power. The check engine warning light was illuminated. The vehicle was restarted immediately. The vehicle was taken to a dealer, where it was diagnosed and determined that the engine had an air leak with the fuel. The contact added that the leak was stopped after an undisclosed repair, but the failure reoccurred a day later. The vehicle was taken to the same dealer however, the failure could not be duplicated. The vehicle was then taken to the same dealer and was diagnosed and determined that the throttle body needed to be replaced. The vehicle was repaired, but the failure reoccurred two days later. The manufacturer was notified of the failure. The failure mileage was approximately 72,700.

While driving the oil light started flashing then the check engine light started flashing with no prior warning. The car was checked, it had burnt up the oil in it and then I put 3 quarts in it. It was 200 miles from needing an oil change. The engine had little to no power once oil was put in it. It died on the side of a highway. It had to be towed to a mechanic. There was no prior warning to this incident that the oil was low. This car put me and my child at risk of car accidents when on the road trying to get home with traffic behind me because the car wouldn't accelerate. I called Hyundai and they said they wouldn't help with no recall or extended warranty on the car.

I recently inquired about this vehicle that was for sale at Grayson Hyundai. It's has a KSDS that needs service immediately and the pre-owned manager is not willing to do that; in fact he's refusing because "They aren't Hyundai" when that is a lie and his dealership can definitely do that service. Safety is a huge concern because the engine could potentially catch on fire or worse. Nothing has been inspected or replaced or fixed at this dealership. I did not go to the dealership myself so I don't know what lights could be on. But with the recalls and this KSDS campaign service needing to be done I don't think there is anything else wrong with the vehicle.

2020 Sante fe with 59000 miles on it. Air stops blowing cold, I look it up and there is a TSB for the Evaporator Temperature Sensor from May of 2021. This is a safety issue because if you run the air conditioning or defroster if the sensor is bad it clicks off the compressor which can affect the fan and overheat the car. I watched it happen on my car when they ran the diagnostic trying to fix it. It came up as a bad sensor, and it clicked off the compressor. The fact that a 6 year old car with 59000 miles needs work on an air conditioner is ridiculous and in this case not safe.

To Whom It May Concern, I am writing to formally report repeated safety system failures in my Hyundai vehicle that have resulted in significant injury and ongoing hardship. The first incident occurred in 2021, when my vehicle was struck from the front by another driver who fled the scene. Despite the impact causing visible front-end damage, the airbags did not deploy, and the seatbelt did not engage properly. The vehicle was repaired by an authorized Hyundai dealership, yet at no point was I informed that the vehicle’s safety systems might be compromised or that it should not be driven. The second and more severe incident occurred in December 2024, when my vehicle was rear-ended by a commercial truck and subsequently pushed into four other vehicles. Once again, neither the airbags deployed nor the seatbelt engaged, resulting in multiple bodily injuries for which I am still undergoing treatment. After reporting this second failure to Hyundai, I was informed that the airbags and seatbelts may not activate when the vehicle is struck from behind. However, this explanation does not address the fact that the same safety failures occurred in the 2021 front-end collision as well. I believe these repeated malfunctions indicate a serious defect in the vehicle’s safety restraint and airbag systems that poses an ongoing danger to drivers and passengers. I am requesting a full investigation into these safety system failures, including whether the dealership’s repair process or Hyundai’s design or manufacturing contributed to these malfunctions. Due to these failures, I have experienced significant physical injury, emotional trauma, and ongoing medical issues, and I am seeking appropriate accountability and resolution.

2020 Hyundai Santa Fe Limited AWD, VIN [XXX] , 30,000 miles. Air conditioning fails to blow cold air; climate control displays -10°F, indicating a defective evaporator temperature sensor per Hyundai TSB 21-HV-002H (2021). Dealer diagnosed evaporator/thermostat failure, quoted $2,500, despite TSB specifying a $30–$50 sensor replacement. Vehicle is 9 months past 5-year warranty but under 60,000 miles. This known defect causes driver discomfort and potential visibility issues (fogging in humid conditions). I have dash photos and dealer quote. Request NHTSA investigate for recall due to widespread HVAC issues in Hyundai models. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On [XXX}, my 2020 Hyundai Santa Fe SEL 2.0T (VIN: [XXX] ) experienced sudden complete engine failure accompanied by a strong burning smell. The vehicle would not start or turn over, stranding me and creating a safety hazard. The burning smell indicated potential fire risk. This appears to be related to the known Theta II engine defect that has caused multiple recalls and engine fires in Hyundai vehicles. Despite dealer confirmation that the engine was clean and well-maintained with no customer fault, Hyundai has denied warranty coverage. The sudden failure pattern with burning odor represents a serious safety defect that could endanger drivers and passengers.

I am writing to formally express my serious concerns regarding an ongoing safety issue with a certified used vehicle I purchased from McDonough Hyundai, [XXX] , in December 2024 and the dealership’s repeated failure to resolve the issue, even after a car accident occurred due to this malfunction. Two months after purchase, I discovered that my horn did not work when I attempted to use it. I brought the vehicle back for service and was told the issue had been resolved. However, the horn continued to malfunction. I have returned to the dealership approximately five times with the same complaint. Each time, I was told the horn works, yet it continues to fail intermittently. In June 2025, I was involved in a car accident and was unable to alert the other driver because the horn did not work. Despite the severity of the situation, no one at the dealership has taken appropriate action to identify or correct the issue. During my most recent visit, Service Manager [XXX] witnessed firsthand that the horn did not work. His technician pressed it once, and because it worked in that moment, the vehicle was returned to me without further inspection. This intermittent failure has still not been addressed. I have time-stamped video evidence showing the horn failing just two days after the last service visit. A non-working horn is a major safety hazard. The repeated dismissal of this issue is unacceptable. I expected better from a pre certified used vehicle. I would be happy to provide any information needed to resolve this issue.

While at a complete stop at stop light, the SUV jerked a few times and when attempting to drive the accelerator pedal the SUV would not respond. I then put in park then back in drive slow acceleration, was able to pull over. After turning SUV off and waiting a few minutes , turned SUV back on engine light is on. Home is 10min. away, engine light is on and acceleration sucks. By time I park the engine light is off. Wait 2 hrs. drive around the block no light acceleration is off.
