What 162 owners told NHTSA about the 2021 Hyundai Santa Fe Sport

I ran into a pretty dangerous situation while on the highway. I was driving at about 70mph picking up speed to pass a vehicle on the far left/fast lane when I suddenly noticed a loss in power (no warning, nothing!). I could hear the engine rev when stepping on the gas but the speed never picked up. I managed to stop on the far left shoulder next to the jersey barrier since there wasn't enough speed to safely get to the right shoulder. Restarting the car multiple times didn't fix the issue but the engine light came on at this point. I had to get the car towed to the nearest dealer after seeking help from the highway patrol and roadside assistance. After 3 weeks at the dealership, they told me they could not replicate the issue and asked me to take possession of the vehicle. The very next day, while on the highway, I ran into the same issue just after driving 7 miles. Again, it could have been pretty dangerous. It's now back at the dealership.

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.

The passenger door has a sharp edge at the bottom exactly like the palasade hyundai recall. Both my daughter and my 82 year old mother have gashed their ankle on the door. In the case of my mother she was lucky we did not need stitches! I have a picture of the injury. I made a case submission to Hyundai.

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.

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.

NHTSA ODI 11468074

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.

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.

In July 2021 while driving from TX to WA due to a military PCS with our brand new suv a small rock or pebble hit the windshield on the passengers side. I called progressive/ safelite right away to have them fix it upon arriving in WA. It was good to go until a few days later i climb into my suv (which is sitting under a car port) and see that the chip has ran through all the way to the other side of the drivers view. From July 2021 it took till Jan 2022 to get a replacement. Had to pay the $500 deductible. However this should not happen on a brand new 2021 Santa Fe that was just manufactured in May/June 2021. More and more i am seeing reports of windshields cracking and I need to have piece of mind that our concerns are heard and fixed to our satisfaction.

While driving the car in cruse control the speedometer would jump up and down rapidly making the car accelerate and break. The warning lights come on saying the forward, side back sensors are off. At times stepping on the breaks a plastic bottle crunch sound will occur but the breaks were fine. I scheduled a repair but was still driving the car. Then I approached an intersection and the light was turning green to yellow so I stepped on the breaks only to have the pedal go to the floor without resistance and no breaks at all. I had to drive through a red light endangering myself and others at that intersection. I pulled into a parking lot and the breaks were working again. Car has been towed to the West Herr Hyundai Dealer on Transit Rd Williamsville, NY for repairs.

While driving in the fast lane on the freeway at speed limit the car suddenly began to slow/stop, after which a warning flashed on the display that said Danger, collision imminent, or something like that. There was no one close in front of me when that happened. This exact scenario has happened three times now in this car, in the same way! I felt my life was endangered every time by the sudden and unnecessary braking of my car.

10/22/21, Mileage ~720, while driving on the highway I had two incidents when the car did not respond to throttle application. In the first instance while attempting to accelerate mildly on a level road the rpm went to 3500 with no acceleration. I backed off the throttle and the car resumed normal operation. In the second instance while attempting to accelerate mildly on a level road the rpm showed about 1500 with no acceleration. I backed off the throttle and the car resumed normal operation. I had no further incidents and returned home safely. There were no warning lights, messages. This is the first problem I have experienced. I think this may be a transmission problem. Similar incidents have been reported online by Hyundai owners with the wet DCT that my car has. I have not yet contacted my dealer about this problem.

Smart Cruise Control relies on the inconsistent and consequently unreliable performance of the of the front-mounted radar. Otherwise-reasonable operation of the Cruise Control would abruptly terminate 1/3 to 1/2 of the intended use-time, illuminating the master warning light (the amber triangle with internal ‘!’) that was accompanied by either a ‘1’ or ‘2’ encircled by red and may or may not have included the Collision-Avoidance warning light. Subsequent examination of the rectangular shield in the center of the grill very rarely revealed more than 2 bug remnants. When the Smart Cruise Control was in operation it would abruptly apply the brakes when approaching or passing a truck in the lane to taffiche right. There appeared to be no similar conditions to the size or shape of the truck or trailer when these events would occur. None of these events applied to congested tr conditions, just otherwise open road. The ’21 Hyundai Santa Fe does not appear to accommodate any mechanism to revert to conventional cruise control, omitting the influence of the erratic front radar system. Trips to two dealerships have yielded no redress to this malfunction.

Car would not start; battery was too low to activate lights or locks, let alone starter. An attempted jumper cable connection to an older car was insufficient to make the motor turn, even after just running the assist car while connected for 20+ minutes. A subsequent jump from the AAA 2000 Ah jump pack did work although their ‘test’ indicated battery state-of-charge and state-of-health to be less than 30%. Their obvious recommendation was battery replacement and, with the vehicle now running, a drive to the dealership was attempted. At the first intersection a full vehicle stop engaged the engine Stop-Start function, but without sufficient battery for the ‘Start’ part. Not only would the vehicle not restart but there was insufficient battery power to put the transmission into PARK nor engage the emergency brake to prevent the vehicle from rolling into busy cross-traffic; only the service brake worked. Fortunately, a nearby motorist recognized the emergency and placed rocks under the tires to prevent the vehicle from rolling forward. The vehicle was towed to the dealership where the battery was replaced without significant comment on the total failure of nearly all systems in the event of battery failure. The outcome of this major battery failure could have been catastrophic as the ONLY system even marginally functional was the non-power-assisted service brake.

I bought a new 2021 Hyundai Santa Fe SEL in January 2021. The vehicle occasionally will not shift out of first gear unless you slow down to almost a stop and then accelerate again. It began within the first month or two of owning. Hyundai has had it in the shop three times. Two times they said they couldn't duplicate. One time they said they showed it went to 4000 RPM's without shifting on the diagnostics before it was slowed down as I told them. They did an update on the TCU and reset the transmission on May 10, 2021. On August 4, 2021 the transmission stuck again. (It went to 5000 RPM's without shifting before I slowed it to almost a stop) This problem has happened about eight times since it began. The GM at the dealership I bought it from said Corporate wouldn't buy it back or get involved without them duplicating the problem. I emailed Hyundai consumer complaints on August 17, 2021 and on August 18 received an email stating I had a case # and would be contacted shortly. On August 24 I called Hyundai customer complaint and was told I had a case manager assigned and they had until August 31 to reply. They did not reply and on September 1, 2021 I called Hyundai complaints again and they said I did NOT have a case manager and that they had not sent it to corporate yet but someone would call me at some point. I feel Hyundai is not concerned about this dangerous problem with their vehicle or my safety. I am beyond frustrated. Jeremy Kimrey

This vehicle is the first Santa Fe that only comes with adaptive cruise control and there is no way to disable it and set regular cruise control. Here are just a few examples of the safety risk. We were on State Highway 29 which is a rural 4 lane highway. There were 4 cars near us. Our cruise was set for 70mph. A vehicle came in front of us to pass which it did. There was no issue. However, our vehicle saw this as a threat and our vehicle slowed from 70mph to 50mph until the other vehicle was out of the set car length distance. Meanwhile the other cars around us had no indication or warning why we would have slowed down this much and we were nearly rear ended. There was screeching of tires and brakes suddenly applied by the other vehicles. All for nothing. I am on the highway with the cruise set at 75mph when again vehicles will come in front of me and my vehicle slows from 75 mph to 54mph, causing the surrounding vehicles to not know what is going on and I hope they are paying attention because there is nothing really going on other than normal driving. It is terrifying to have your vehicle control itself and you don’t know when it will start to accelerate again so for the most part, I am shutting the cruise control off and on constantly. At our most recent Hyundai service appointment for this problem, we were told by Hyundai Care Manager that this is exactly how it’s designed and there is no problem. And we’ve been told just simply don’t use the cruise control at all. That is not a solution. We feel like all these “safety” features are creating a sense of driver coma on our roads. Instead of the left lane being used for faster cars as a passing lane, the adaptive cruises are creating a chain of vehicles that are well under the speed limit
