2021 Hyundai Santa Fe

When ISG (Idle Stop and Go) is ON, vehicle will completely turn off when pressing brake to stop. Vehicle shut off on me yesterday yielding to turn onto a busy highway. It took 5+ mins for vehicle to crank back up. Very dangerous! No warning lamps, messages, or symptoms other than vehicle completely shutting off. An appointment has been made at Hyundai dealership next month which is the first available time. Please look into this issue before someone is seriously hurt or killed!

While driving on the interstate where no other vehicles were within eye view and no overpasses my sunroof glass exploded. It sounded like a gunshot and it wasn’t until I heard the glass rattling above my head that I realized where it was coming from. Luckily I had the cover closed so majority of the glass was caught by that. The incredibly loud noise startled me tremendously and could caused a collision because of my focus being taken away from the road. The shattered glass was in my lap, on my hand, in my hair ect. causing small cuts with the potential to cause serious harm had the cover not been closed. No, it has been several weeks almost a month and the dealer is requiring confirmation from corporate case management before it can be assessed. Corporate has been “escalating” my case yet a caseworker was not assigned my case this whole time and once a caseworker was finally assigned on 7/8 I had yet to hear from them so I attempted to call on 7/11 and was given a further run around. I am riding around with a plastic bag and tape fastened to my car to hopefully prevent water damage from occurring going on a month now. The bags are so loud when driving that they prevent me from being able to hear what’s going on with my surroundings on the roadway which is unsafe No.

I keep my vehicle backed into my single car garage. I have had 3 incidents in the last couple of months Beginning of mayish to now, where I start the vehicle, put it in drive and it does not drive. Twice it started to reverse and today it acted as though it were in neutral. I've taken video of the last 2 incidents showing that drive is selected, the dashboard and the Birdseye camera. My dealership is working to resolve but has stated to plan on my vehicle being there for awhile. This seems to be quite dangerous. When I turn the vehicle off and restart it, drive works.

Problem first started on 3/31/22, car starting showing engine light as well as forward safety system off. Car would not accelerate and was shaking spuddering when foot was off the brake. Pulled into a safe location and called Towne Hyundai Genesis of Denville (Rt. 10, NJ) to schedule a service appointment and was told that there were NO appointments or availability until May. I expressed my concern that I did not feel safe driving the vehicle and the response was that I could drop off the car for 4-6 weeks and they would look at it when they had a chance. I asked if there was a loaner car available and they said no that 100's of other people have problems. I took my car to a local shop to see if they could diagnose the issue and they ran a diagnostic test and the error P2127 (Throttle/ Pedal Position Sensor/ Switch E Circuit Low). The Hyundai BlueLink shows 2 alerts for Chassis on 3/31/22 as well. After this date I felt unsafe driving my car and have drove the vehicle a handful of times in 2 1/2 months unable to get an appointment. The alert would come on as soon as you turned the vehicle on until 6/4/22 when it occured while driving on a highway and the car stopped accelerating. I took the vehicle to Hyundai and they updated the system and stated that it was fixed. Within 15 minutes of driving it the issue came back, and I called them and they once again stated that I could leave it there for 4-6 weeks without a loaner. This car is extremely unsafe as it will just stop accelerating without any warning.

Most of the time, when the vehicle stops the transmission slams and pushes the vehicle forward requiring additional breaking effort. This problem started before 5 thousand miles of use. I reported it at his first oil change and I have continued to report it. The Hyundai dealer's machine shop claims to test and verify it, they claim they have no problem or technical bulletin about it. They say this is normal for this model. My concern is that this fault ends up breaking the transmission in the middle of the avenue and having a traffic accident. There is a forum of this same model owners reporting the same problem, https://www.hyundai-forums.com/threads/2021-santa-fe-transmission-shudder.680164/page-2 apparently they don't know this website to report these problems.

The vehicle sporadically turns off its engine by itself, mostly stopped when placing the transmission in park gear. One time the engine went out in the middle of the avenue. After these events when starting the engine it makes a noise for a few seconds. I have taken the vehicle to the dealer and they say that there is no type of technical bulletin on this type of problem.

Problem #1 - At least 4 quarts of oil spewed from the oil tank and covered most of the engine for an unknown period time. There were no notifications, alerts, or any other indication concerning the oil tank having 1 or less quart of oil. Ultimately, there are at least three (3) questions that need to be addressed 1.In a 2021 Santa Fe, what would cause both the timing and valve covers to leak out at least four (4) quarts of oil out of the oil tank onto the engine. 2.Why was there no notification, alerts, or indication that the oil tank only had less than one (1) quart of oil. 3.What other damage could there have been to the engine beyond the several parts identified as needing to be replaced, that was not identified. A Chronological Order of Events is available.

My Santa Fe has less than 14k miles. In many instances, the car has stalled when turning on. The engine would tremble and then shut the engine off while the dash lighting/symbols stay on. It will idle for a quick second and then drop to zero. Another instance is when driving into a parking spot and driveway and we applied the brakes. At that moment the engine shut off while the dash lights/radio and everything else stayed on. In all instances, if we apply the brake and then hit the start button, the car will typically turn on and act like nothing ever happened. In 2 instances, the blind side detection would turn off while driving and all the warning lights would come on the dash. After turning it off and letting it sit for a few minutes it would disappear. One time the front detection would go off and there was no car in front of me for about 8ft. The beeping continued after we drove off and it eventually reset itself and never happened again. I’ve notified the Hyundai dealer but they claim if they can’t recreate it then they can’t fix anything. My previous Santa Fe did the same thing and they had it for 2 weeks with no results. Although my blue link app showed the car was never moved from the parking spot which made me wonder if they even tried anything. I have videos of the Santa Fe stalling.

The contact owns a 2021 Hyundai Santa Fe. The contact stated that while driving at various speeds, the vehicle would not immediately accelerate while depressing the accelerator pedal. The contact indicated that the RPM would increase however, the vehicle would hesitate to accelerate causing a safety hazard while pulling into traffic. The vehicle was taken to the local dealer who was unable to diagnose the cause of the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 50.
