2021 HYUNDAI SANTA FE Complaints

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.

The windshield has waves through it causing parts of the windshield to be blurry.

While driving the crash avoidance emergency braking came on out of nowhere, and the steering locked up. I was driving on a straight and level roadway with no vehicles in front of me when suddenly the whole dash lit up with warning lights and the car, a 2021 Hyundai Santa Fe, came to a emergency stop, the steering wheel was shaking and wouldn't turn. This was the second time this happened. The first time on 09/29/22 I called the car dealer and was told that "They knew of the problem and that there was no remedy". This is extremely dangerous, both times it happened while I was driving on a highway at a steady speed, thankfully the roadway was dry if it had been raining I would have probably crashed.

While backing out of our garage, the “eyebrow” glass portion of the panoramic sunroof shattered. Nothing struck the glass. Our insurance is paying for the repair and rental car for a week. Hyundai will not cover the glass damage under the warranty. Online searches indicate that Hyundai has a lengthy history of faulty panoramic sunroofs.

The vehicle will not move forward or reverse, when drive or reverse is selected. The car has been at the dealership since 10/11/2022. I was informed that the transmission needed to be replaced. No one in the hyundai organization (including the dealership) can tell me when replacement will be.

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.

Having issues with the dash going completely black; so you can not see any instruments on the dash panel or the head unit (navigation/radio/airplay). The car has been into the shop three times so far with no resolution. The newest issue; the horn doesn't work, the safety features such as lane assist, lane departure etc. only work intermittently, and I have had the brakes slam on for no reason. The last time I took the car back to dealer and told them I was afraid to drive the car, the service manager changed the settings on the safety features, not sure how that was to fix anything? We have been so close to being rear-ended because of the faulty braking system. The electrical system is having major issues, I have videos of the car doing all these things and have showed them to the dealership and they claim they can not fix the car because it doesn't happen when they drive 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.
