2017 Hyundai Santa Fe Electrical System Problems

After performing regular oil changes, and even a new fuel pump sensor, I experienced an issue. Last oil change was within the past two weeks. Driving home from the mountains, I heard a knocking sound from the engine bay. I narrowed it down to all gears above 2500RPM, increasing knocking with RPM speed. I took it easy on the engine, mostly coasting down the mountain. Suddenly during acceleration on an uphill, a pop sounded, and copious white smoke started coming from the engine bay. I pulled over despite having no power brakes but I was fortunate to be near an off ramp in a rural area. Trying to troubleshoot roadside, i noticed fluid on the tie rod, but I wasnt able to determine what kind of fluid it was. When I try to start the car, there is one single click, the engine wont even attempt to turn over. Oil, battery and check engine lights are all on. After towing, I found that the fluid leaking from the vehicle is oil. The vehicle is currently at a transmission shop, but from my research, this isnt a transmission issue but a blown rod bearing the Hyundai engines are know for. I will be contacting a dealership to see if they will at least confirm my diagnosis.

Odometer Fraud. The contact purchased a 2017 Hyundai Santa Fe on March 11, 2024, from a private dealer with approximately 46,000. The contact was informed that the vehicle had only one owner who had leased the vehicle. Recently, the vehicle was taken to an independent mechanic where the vehicle was diagnosed with engine failure. The mechanic retrieved a Carfax report and discovered that the vehicle had five previous owners and there were several mileage discrepancies. At the time of purchase, the vehicle mileage was approximately 46,000. However, it was discovered that the last known accurate mileage on the vehicle was 113,000.

Bottom brake lights will not work but top high brake light works. I was stopped by police three times. They state all three brake lights must operate.

The contact owned a 2017 Hyundai Santa Fe equipped with a Rockland Electric Mobility Scooter Lifter, Part Number: 10101194. The contact stated that after the mobility scooter lifter was installed on the vehicle, the vehicle experienced electrical failures. The A/C became inoperable, and the hatch opened intermittently.

There was no property damage. There was no physical injury sustained. The contact sustained mental trauma, causing headaches and the right side of the lip to quiver. The contact had called Gregory Fox, an investigative reporter and anchor at WESH 2 News(NBC), who notified the manufacturer of the failure. The manufacturer followed up with the contact and informed the contact that a third-party investigation would be conducted to determine the cause of the fire incident. The vehicle was towed to a salvage yard, where a third-party investigation was conducted, and the manufacturer informed the contact that the fire was caused by the Rockland Electric Mobility Scooter Lifter. The vehicle was totaled. The failure mileage was approximately 63,000.

While driving- in total movement- the car completely shut off. Without any prior warning or indication. Immediately after, the car restarted, drove a couple blocks over, continuing to shut off while driving. It was then towed. How was your safety or the safety of others put at risk? The warning lights did not appear until AFTER the car quit. They all came on & flashed & quickly went back out. Uncertain which component misfired or is affected- possibly related to an engine or fuel/ cylinder failure. Car is at mechanic for inspection. Our safety & lives were in critical jeopardy as the vehicle stopped without warning while driving in traffic congested area. It is unknown if this is a known issue or if this situation has been replicated however the current mechanic facility has experienced the same issue with this vehicle. Also strong odor of gas was experienced during shutoff.

The contact owns a 2017 Hyundai Santa Fe. The contact stated that the automatic power door locks failed to operate as needed. Due to the failure, the contact had to manually unlock and lock all doors inside the vehicle. In addition, the contact stated that the button to unlock the gas cap also failed to operate as needed. The vehicle was not yet diagnosed or repaired. Neither the dealer nor the manufacturer was notified of the failure. The failure mileage was approximately 72,000.

While driving, the vehicle lost its brakes and rolled to a stop on [XXX] at that point the vehicle compartment began to fill up with black smoke and soot and flames started to come out of vents. My daughter immediately grabbed her dog and exited from the vehicle to a safe spot away from the car. Within 10 seconds the vehicle exploded and erupted into a 20 ft fireball. If my daughter would have hesitated she could have been killed. Hyundai inspected the vehicle and found nothing conclusive except that this problem has been documented in other Incidents. The vehicle was declared to be totaled. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My complaint is the dealership that said had completed the recall on my brake systems according to both your and state records was not completed. They gave me a service notice stating the work was done. Since then the braked have continued to act up and the vehicle as a strange acceleration problem. The dealership is Don Wood Hyundai in Athens Ohio.

In June 2024, my vehicle suddenly lost power while I was driving on the freeway, almost causing a serious accident. I managed to restart the car after being stuck on the shoulder of the freeway for several minutes. The same issue occurred the following day, prompting me to have the vehicle towed to the dealership. Hyundai Motor was contacted since the vehicle is still under warranty. The dealership informed me they would conduct an oil consumption test three times to diagnose the issue. However, they also stated that for the test to be successful, I needed to replace unrelated parts, including the brakes and transmission oil, among other items. Reluctantly, I agreed and spent $1,800 on these replacements. After completing the first oil consumption test, I returned for the second test. However, the dealership informed me that no further tests were necessary and returned the car to me without addressing the underlying issue. I emailed the case manager assigned by Hyundai to report this, but I never received a response. A few months later, the car failed to start. I contacted Hyundai again, and they dispatched a tow truck. The tow truck driver managed to start the car. A few days later, the issue recurred, and the roadside assistance tow driver suggested it might be the battery. Out of frustration, I paid $300 to replace the battery. Despite this, the car continued to make unusual noises at startup, a problem I had repeatedly mentioned to the dealership and in my communications with Hyundai. The situation reached a critical point today when my wife was driving the vehicle on the freeway with our five children inside. While traveling at 60 miles per hour, the car suddenly lost power again, putting their lives in danger. This is the third time this hazardous issue has occurred, and I fear for the safety of my family.

The liftgate randomly closes and I have to jump out of the way to avoid it hitting me. This obviously poses a huge risk to my young children when they are nearby. In addition to that, the liftgate will sometimes only open a quarter or half of the way, sometimes all the way then suddenly reverse and start closing, and sometimes does not open at all. I've gone on Hyundai forums online and found numerous other people with the exact same complaint. Seems to be effecting cars made from 2016 - 2020. I have multiple videos of this but can't upload them as you only accept pictures.

I bought this vehicle back in 2022 hearing how great Hyundai is wanting to make a long time purchase with a for my family. I’ve had different models vehicles but I wanted something reliable. Now hearing this is possibly a fire hazard I need all this taking care of immediately . I am dependent on my car to get to work, for food, and I take my kids to school an to practice and just everyday life. I will take my vehicle to the dealership immediately to attempt to get this taking care of this week an hopes this company can make it right. Thanks for your time

Sun roof has opening and closing issues. No warning signs. Could very well cause major issues, broken glass, damage to electrical, interior due to water etc. called dealership with no luck.

Vehicle has intermittent engine stalling, but is still running. Possible dangerous situation if making left turn with oncoming traffic. This has happened to many times since my owner ship. Bought this car used. I am 2nd owner. 33k mi when purchased in 3-2021

My engine failed with regular oil changes at less than 120k miles with NO warning. It was 9 at night and it completely shut down on the highway. The hazards, brake lights, etc were not operable! I was almost hit by traffic three times due to not being able to turn on hazards and brake lights not working. I could not even place the car in neutral. Thankfully, the local police department was finally able to assist me but it was a frightening experience and Hyundai is doing absolutely nothing about it.

I was driving on the highway, and suddenly oil and battery light came on and engine stopped and I had to pull over. The only warning was the check engine light came on when I started it 10 minutes before the engine died.

Hyundai Safety Concerns. The details of the incidents are as follows I own a 2017 Hyundai Santa Fe sport turbo on Saturday June 24th while driving down the palmetto expressway at about 70 mi an hour the vehicle suddenly stopped. It was a very dangerous situation with my family aboard we were lucky to have Florida highway patrol toys to a safety location. The car was completely dead and the vehicle was told to homestead Hyundai dealership for repairs 4 days after delivering we received a call letting us know that the computer had been damaged due to a oil leak in the engine that was repaired by them 10 months prior. It has come to our attention that there are recalls for this vehicle for crankshaft problems it is a concern that this is a safety hazard for us and that the dealership is not being transparent with us is the consumer. We have emailed Hyundai Motors Corporation and filed a complaint. I kindly request your immediate attention to this matter, as the safety of my family and other drivers is at stake. I trust that the National Highway Traffic Safety Administration will conduct a thorough examination of the reported incidents, the dealership's actions, and the potential risks associated with the 2017 Hyundai Santa Fe Sport Turbo. Your intervention and expertise are vital in ensuring consumer safety and holding accountable those responsible for any negligence or lack of transparency. Thank you for your prompt attention to this matter. I eagerly await your response and hope for a swift resolution to this alarming situation.

On June 22, 2023, I went to start my 2017 Hyundai Santa Fe in a shopping center parking lot. I had recently driven from the Pgh airport to Monroeville and stopped to run errands. Upon reentering my vehicle I used the push button start to start the car. The engine started and the center computer screen turned on, however the dashboard did not light up and I was not able to shift into Reverse. I cycled the car ~5 times trying to get it going, but the same start-up happened. Upon calling husband (after trying to start another few times) he recommended that I look at the fuses. At this point I opened the driver side door and was outside looking at the fuse panel. This is when I heard someone shouting from the highway across from the parking lot that my car was on fire. I looked at the rear of my car and saw flames coming from the rear bumper. I quickly stepped away from the vehicle. The entire drivers side of the rear bumper was engulfed in flames. Both the police and fire departments came to the scene. We were collectively able to extinguish the flames and the car was totaled.

The engine seized without warning or notice. No warning lamps came on to indicate anything wrong with the oil pressure, engine, or anything else. I received notices for low gas from time to time, but never anything concerning the engine. I heard engine noises the day before the engine seized. The next day it failed. The car was inspected by the dealership and Hyundai to determine whether the cost would be covered by them and this is what was reported to me in the cost for repair: “Engine Rebuild/Replace: 3.3L LONG BLOCK, GASKETS, AND FLUIDS This is the entire process needed to either rebuild or replace the vehicle's engine. This is a process needed when the vehicle's engine is in need of serious repair.” I was denied coverage because my VIN number was not on the recall list for 2017 Hyundais. I believe it was recall 168. When I looked into it, I read exactly what happened to mine. My safety was a concern because the engine stopped while I was driving and I had to coast into a safe area without causing an accident. I was told by the dealership that this was a common problem for 2017 Hyundai Santa Fe’s but the recall is not for all of the Hyundais this problem has happened to. I was told by a former employee of Take5 that Hyundais burn oil quicker than most cars. I can’t confirm that the issue was from a lack of oil, but from what I’ve read, that could be the main issue. I believe a warning on the quickness of oil consumption should be put out as well as an improved warning system/sensors for this make and model.

On May 2023, while my husband was taking my daughter to go to school with 2017 Hyundai Santa Fe, he noticed engine knocking noises emanating from the engine compartment. Shortly after, the vehicle's performance significantly deteriorated, and the check engine light illuminated on the dashboard, and the engine shut down. Get the car towed to the nearest auto service, the mechanic told me that there’s an engine failure as result of abnormal oil consumption causing internal damage and need to be fixed by Hyundai. I called Hyundai USA, and was told that in order to have it covered under the warranty, it needed to be repaired by an authorized dealer. However, no authorized dealer had an available appointment for at least 2 months. Finally after 2 months, I had the car towed to the authorized Hyundai service center for diagnosis and repairs. Upon examination by the certified technicians at the Hyundai service center, I was informed that it needs and engine replacement that will cost around $20,000. I called Hyundai Corporation and had escalated my case to the case manager, but the manager never called back to give me an update. Their customer service department is also frustrating to deal with. They just sort of repeat the same phrases over and over again rather than having any sort of actual conversation with you. It's been more than 2 months after the incident and they finally they can’t do anything about it because it’s outside of warranty. It’s very frustrating

Car began to smoke from engine compartment. Stopped car in a driving lane on interstate 78 where construction barriers had closed both shoulders. Car then burst into flames. Car was a total loss before fire trucks were able to arrive. Just prior to the fire the Warning light for the abs system malfunction appeared on the dashboard.
