When driving on the highway the suv would not change gears. It felt like it was stuck in 1st gear, reving very high. Was unable to move the suv to the side of the road. Came to a stop with heavy traffic blowing there horns. Put the suv into park, switched it over to sport mode and was able to get going. This is the third time the suv has lost power. Also have noticed the transmission has been taking to long to change gears.

On January 26th, 2023 at 9:57am the vehicle was unable to shift into reverse, drive, or neutral. The vehicle's system sent automatic messages indicating to have the transmission control system checked. We had the vehicle towed to a Hyundai dealer to be serviced. The dealership advised they performed a software update and that nothing else needed to be done. Then on January 30th, 2023 at 7:44pm the vehicle's check engine light came on and the vehicles system sent us another notification to our phone and email that there was a transmission control system issue. The vehicle shakes abruptly when accelerating after a stop. I have photos of the warning messages as well as video of the car shaking.

I was accelerating after being at a stop sign onto a major two lane road when all of the warning systems came on and the car stalled while the front of the car was partially on the major two lane road. The alarms, including the collision warning were going off, and it took me several minutes to restart the engine. I was very lucky that I was not hit by oncoming traffic. This was immediately reported to our local Hyundai dealer. They took two weeks to schedule our appointment and then told us nothing was wrong and that everything "checks out". Today, I receive the recall notice telling me the loss of power "could increase the risk of a crash" and yet they do not yet have a fix for it. This means I am paying for a car that is unsafe to use with no remedy in sight. Had this occurred on the highway, I would have been killed.

The contact owns a 2021 Hyundai Santa Fe. The contact stated while making a turn from a complete stop, the vehicle responded but suddenly stopped. There was no warning light illuminated. The contact turned off and restarted the vehicle 5 minutes later. However, upon depressing the accelerator pedal, the engine made abnormal roaring sounds. The contact was able to drive after several attempts and pulled into a parking lot, however, the failure reoccurred. The contact restarted the vehicle and pulled into a parking spot. The vehicle was towed to the dealer where the failure could not be duplicated. An unknown software update and an unknown repair were completed; however, the vehicle hesitated to respond while driving and depressing the accelerator pedal. Additionally, the check engine warning light was illuminated. The vehicle was taken to a second dealer, Key Hyundai (4660 Southside Blvd #100, Jacksonville, FL 32216) where it was diagnosed that the transmission needed to be replaced and that the failure was associated with NHTSA Campaign Number: 22V746000 (Power Train). However, the parts for the recall repair were not available. The vehicle was not repaired. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was notified of the failure and a case was filed. The failure mileage was approximately 11,900. Parts distribution disconnect.

There were two warning (?) "bings" from the instrument cluster and then vehicle completely lost power and would not exceed maybe 2 MPH. Vehicle had forward drive, but no willingness for engine to speed up beyond idle speed. Was like this for several city blocks until I was able to restart at a traffic light and then it resumed normal operation. Did not notice any warning lights and no messages popped up in the instrument or vehicle display. Just the two "bings" before power loss. This is actually the second time this has happened. Last time was while accelerating on a freeway onramp, but vehicle corrected itself more quickly and without need for restart.

Car was bought approximately a year and a half ago and it was working fine until last September 2022 when it started to stall the engine when having ISG (Idle Stop and GO) ON. It has no pattern, but during the last 2 months it has shut down more than a dozen times. I've taken the car for inspection at Hyundai (2 times so far) and they can't find any faults when running a scan and said that they car is just fine. They assured that an ECM update would solve the issue but it has not improved anything in the car. The car has continued the pattern, when you stop the car it starts to shudders before stalling the engine, all without any error lights. Next November will be the third time bringing the car for the same issue without any resolution. Also, as a minor problem, it has started disconnecting the cellphone from the apple car and you can't reconnect it unless you turn off the car.

While driving on the highway, when I pushed on gas pedal the car would not accelerate, I was uncertain if I was losing power of the vehicle, luckily it maintained the current speed and did not decelerate, but I was unsure at the moment if I was losing complete power, because it wasn't responding, it felt like the car was going to stall similar to when you run out of fuel. This occured for around 20 seconds, i would guess, long enough to notice that the car was not responding and continued to not respond, and to be concerned from a safety perspective. The night before I had filled the fuel tank and I noticed to guage that predicts fuel mileage kept changing by 3-5 miles difference, back and forth repeatedly, before I even left the fueling station and as I continued to drive. I'm unsure if that is related to the driving performance issue of not accelerating the next day. The next morning when the non acceleration occurred the predicted fuel mileage was consistent. The next time I drove the vehicle following the non accelerating issue, there was an error that popped up on my digital dash stating "A possible condition with your engine control system has been detected. A full system check is recommended to be done when convenient. Please contact your local dealership to schedule an appointment." Also, the check engine light came on. MyHyundai app showed a DTC - P040B00, DTC system - powertrain, DTC sub system- EMS. I took the vehicle to the Hyundai dealership to confirm that the car was safe to drive or if I should rent a car until it can be further inspected. They read the codes and said it is safe to drive and no additional information, I will be taking the car back to the dealership in a week, which is their first available appointment with a hybrid certified technician. Both the dealership and Hyundai corporate customer service states there are no current recalls, but through other car forums, it appears to be a similar issue that has occurred with other Hyundai models.

This SUV has been plagued with issues, and yet after 5-6 visits to the dealership, they don't seem to be able to fix them all. The vehicle (2.5T AWD) currently has around 14k miles and within the past month the gas pedal suddenly became unresponsive, worst of all while carrying my kids and wife in the car. Coming to a dead stop to cross an intersection, went to accelerate to join traffic and the car wouldn't accelerate. Last time on 9/23 when I almost got into a head-on accident while making a left turn as the car barely moved into the first of three incoming lanes, would not accelerate and so forced me to quickly hit reverse, outrageous! Other three times while making a right turn. Auto engine-off has been disabled on all occasions (hate it); two times happened while driving on smart mode, another one on comfort and another one on sport mode. Car has been always using Mobil, Shell or Chevron gasoline. Which also brings me to another point, the vehicle suddenly started consuming crazy amounts of gas, currently at 16mpg for the past 4 full tanks! The vehicle was dropped off at dealership on 9/26/22 and already filed for Lemon Law in FL as this is absolutely unreliable and dangerous to carry my family on. According to manager at Rick Case Hyundai of Davie, an update for the transmission just came out this week after a recall and so they were going to reprogram. I am still getting rid of this p.o.c.

Car was without power after 16 months and 7500 miles. Got it jump started. Two days after that, car would not start again. Second time jump started. Taken to the dealership (Alexandria Hyundai) where two days after that they found "nothing wrong with the car" and returned it to me. Before that, I asked them to change the battery, they denied my request and I paid out of pocket for a new battery as maybe that was the problem. One month approximately after that, car would not even open. Got it jump started again. Drove to blocks and completely and suddenly shut off in the middle of a busy intersection posing a major safety concern for myself and third parties. Involved 911 and towing. Had to spend 40 minutes depressing the brake for the car not to roll down and avoid an accident. Taken to the dealership again. 5 days after that, dealership found "nothing wrong with the car". 7500 miles inspection done in parallel "supposedly" put the tires at 35 psi per report issued but dashboard shows tires at 30 psi. Do not trust dealership, car poses significant driving and safety concern for me and third parties.

This car since 6/7/22 has been plagued with issues where is starts cutting out and stalling followed by the check engine light coming on flashing. This has happened many times and just happens while driving down the road. It is a very dangerous condition as you can not predict when it's going to stall out. The car has been in the dealership 3X for this problem and spent over 40 days there. Hyundai replaced the fuel injectors claiming that was the problem. It was over 35 days to get the back ordered parts. They were replaced and the car seemed to be running OK. I drove it for about 150 miles and it ran like new. Then on 8/13/22 while driving in traffic on NH Highway US1, it started doing it again. I went into the Hyundai dealership since was right there. I brought the technician out and showing him my running car with the running car with blinking CEL. They pulled into into the shop and ran a scan on it. They said there was no active codes. I asked to leave the car with hem so it could be investigated and there response we "we don;t have a car for you until next Tuesday". I was forced to drive off in a confirmed dangerous car. I pulled out into traffic on US1 and the car immediately lost power and started cutting out and the CEL was back on and blinking. I turned around on the very next street, turned the car off and back on and the CEL cleared. I pulled back onto US 1 and the car immediately lost power and started cutting out and the CEL was back on and blinking again. This very nearly caused a 2nd accident as ad zero power to accelerate. My concern is Hyundai has no idea what the problem is. They know there is a dangerous problem. The service manager drove the car/confirmed himself there is a serious issue. My other concern is the Hyundai dealership knowingly sent me away in a car they had confirmed for themselves was unsafe nearly causing a accident on the highway. I had to speak with the General manager to get a loaner to leave my defective car.

While traveling 70 mph the vehicle had a sudden loss of engine and battery output performance while driving and began losing speed despite the accelerator being fully depressed. There was a very rapid decrease in speed, and no warning chime activated per manual. -€œCheck Hybrid System. Stop Safely, triangle warning displayed.-€ Observed battery indicator rapidly deflecting left and right. The vehicle would not accelerate and had to be coasted through four lanes of traffic to get to the shoulder of the highway. While on an SOS call with Bluelink, who was unable to see the location of my vehicle, Oil Light illuminated, and a message on the dash said -€œCheck Battery Discharge.-€ After the first Bluelink Operator was unable to assist in dispatching a tow truck due to the inability to see the vehicle-€™s exact location, the second Bluelink Operator was able to assist and dispatch a tow truck to the location and tow the vehicle to the closest dealership. The vehicle could not be turned on or placed in neutral. Was given a jump start to place in neutral to tow. Upon arrival at the dealership, the key fob would not register inside the vehicle for the service manager and technician to move with the tow truck operator. The vehicle was evaluated by the dealership and the only reported issue was a signal error that was present when the vehicle arrived at the dealership after being towed. Dealership reported radar was not vertical and contributed that to the cause of loss of acceleration on the highway despite not having identified it before or being a result of being towed. I requested this be reported if truly the cause since that could be catastrophic. The matter was considered resolved by the dealer since it couldn-€™t be duplicated. This unknown, continued sudden loss of output power, acceleration, and electrical power is a Serious Safety Defect and significant impairment to the vehicle, posing a fatal risk for the operator and other motorists on the road. Occurred at 24618 miles.

While I was traveling 70-75 mph the vehicle had a sudden loss of engine and battery output performance and I began losing speed. There was a very rapid decrease in speed, and no warning chime activated per manual. -€œCheck Hybrid System. Stop Safely, triangle warning displayed.-€ The vehicle would not accelerate despite pressing the gas pedal all the way to the floor and had to be coasted off the interstate through three lanes of traffic to get to the shoulder. No fault indications were present in the Bluelink app despite warnings present on the dash. Mileage was 6506 at the occurrence, vehicle was in Smart. Adaptive Cruise Control and Lane Keep Assist were being utilized, when disabled acceleration did not return. I was advised to turn off the car and turn it back on due to no faults present via remote troubleshooting tools and no dealership within 150 miles, and the vehicle resumed operating okay. After taking it for service at the next available -€œemergency slot-€ two weeks later at my local dealership and the car being there for one week, they reported condition could not be duplicated, the vehicle is operating to the manufacturer's specifications. I noted my serious concerns and that a serious safety defect that allows a vehicle to lose all acceleration on the highway and the vehicle not sounding a warning chime can lead to dangerous scenarios on the road and I was assured there was nothing wrong with my vehicle and it would not occur again as it was operating within manufacturer specifications. The vehicle did have a subsequent failure of this same type at a later date. It was not investigated by anyone other dealership. The manufacturer failed to address the loss of acceleration concerns when requested. No chime activated but should have received one per manual. A safety warning was present on the dash, -€œCheck Hybrid System. Stop Safely-€ service warning triangle. I am unsure how long it appeared before the loss of acceleration due to no chime.

I took my car to the dealer because it hesitates when accelerating. I was told since no lights are on there's nothing they can do. This can be very dangerous as it jerks when accelerating

- Toms River, NJ, USA

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!

- Mcdonough, GA, USA

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.

- Hormigueros, PR, USA

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.
