I have been taking my 21 Santa Fe hybrid limited into the dealership for a year and a half for the same code . Powertrain code P040B00, and to this day they can not repair this issue. I looked it up and a ton of us are having issues with this same code. It should be investigated, and customers should be warned. Hyundai needs to recall these vehicles or provide a solution. A year and a half is unacceptable

While driving 80 mph down the highway my brand new vehicle shut off completely, the entire car lost power. In another instance I was going around a roundabout and my acceleration completely went out, my son was in the back seat and another car had to jump the curb to avoid crashing into us. I met a woman in the dealership who has been waiting over a year for her recalled tow hitch to be fixed. When it rains or snows the forward safety systems shut off and the alert repeats extremely distracting on your dash, like sounds, red flashing lights, over and over again. You have to constantly hit the ok button while driving to get it to go away.

From what I have been told there is no recall on this issue. Purchased a Hyundai Sante Fe Hybrid 2021 brand new in 2021. I live in La Quinta California summers are especially hot. Temps can be anywhere from 105 to 120 . Only had the car for 6months when in light came on saying Inverter needs coolant this has been a problem for the past 2yrs. Checked with Hyundai Service department my coolant is fine air conditioning works well. This not a safety issue but should be fixed and Hyundai is doing nothing about it. Many complaints have been ignored.

Whenever the weather gets above 80 degrees outside my car put a notice to refill inverter coolant, when everything is filled max line. I’ve mentioned it twice to the Hyundai service and both times the employee told me not to worry about it and it is a sensor issue. That is unacceptable, I live in Las Vegas, Nevada where temperatures on average in summer are 90+. That’s a big risk an unnecessary danger to have my car engine over heat and stop in the middle of no where and potentially leave me stranded or worse cause an accident or fire. On top of that I have to see the message every day in the summer temperatures, without any way to remove the message. This will be the 2nd summer I’ve seen this message appear in my car, and I’m tired of the dealership & their car service staff telling me this is nothing to worry about… especially on car not even 4 years old!

When turning at low speeds especially sharp turns and accelerating, a cracking sound occurs.

Gas pedal stops working while driving down the road. Happened 3 times. Will work again after awhile. Dealership can't find what's wrong with it and so hyundai and the dealership said they can't fix it.

On December 28, 2022, we were driving 70 miles per hour on Route 75 in the third lane of a four-lane highway from Michigan to Tennessee. In Ohio, the vehicle lost all drive power without warning. As it decelerated, we were able to maneuver the vehicle to the breakdown lane, narrowly avoiding other vehicles around us driving at 70 miles per hour. We do not know what caused this to happen. After several hours on the side of the highway, the vehicle was towed to Jeff Wyler Hyundai in Fairfield, Ohio. They have not been able to diagnose the problem as of today. The contact stated that the cause of the issue was due to an oil plug that was improperly tightened by the dealership during service maintenance. As a result of that, the oil was able to drain out and cause the engine to fail.

The contact owns a 2021 Hyundai Santa Fe. The contact received notification of NHTSA Campaign Number: 22V816000 (Seat Belts) however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The driver's side seat belt failed to extend smoothly. The contact stated that occasionally the seat belt became stuck and excessive force was needed to operate the seat belt. The manufacturer was not made aware of the failure. The approximate failure mileage was 26,000. Parts distribution disconnect.

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.

Refill inverter coolant comes up on my dash daily. I have taken the vehicle back to the dealership several times to get that serviced. After having the vehicle all day they tell me everything is running fine and they can’t find the problem or figure out why the message is coming up. This has been going on since I bought the vehicle in April. They assure me the vehicle is safe to drive and this won’t affect the vehicle in any way. This problem has not been resolved and I’m afraid serious damage will happen if this message keeps coming up and they don’t get it fixed.

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. “Check 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 “emergency 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, “Check Hybrid System. Stop Safely” service warning triangle. I am unsure how long it appeared before the loss of acceleration due to no chime.

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. “Check 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 “Check 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.

I purchased my car in May 2021. Shortly after purchase, I noticed a "clicking" sound under the car when the car was operating between 15 and 20 MPH. I took the car to the dealer, who couldn't identify what was causing the sound. The dealer subsequently replaced the front axle, but the clicking sound continued, only audible when the car was moving at between 15 and 20 MPH. On June 9, I was driving at about 40 MPH on an interstate that had only a few cars on it. I didn't notice any debris or objects in the road, nor did I feel the car hit any debris or objects. Suddenly, I heard a loud "crunching" sound that I mistook for interference from the radio. I turned the radio off and realized the sound was coming from the rear passenger side of the car. I looked at the dashboard and saw the tire pressure light had illuminated. A few seconds later, the triangular danger sign also illuminated. I got off the highway at the next exit and stopped the car as soon as it was safe. The car made a lot of noise as I drove down the exit ramp, and it was difficult to steer, so I knew that the rear tire was flat. I got out of the car and found, to my surprise, that both tires on the passenger side were flat. The rear tire was cracked and ripped apart. The front tire was intact, but completely flat. The car has not been inspected yet, so I don't know what caused both tires to flatten at the same time. If I'd hit something hard enough to flatten both tires, I'd think I would have seen or felt it. My concern is that a defect in the tires related to the mysterious clicking sound that the mechanics could not diagnose caused the tires to blow out without warning at the same time.

The vehicle has a wireless phone charger which causes the phone to overheat. It causes so much heat that the phone shuts down to prevent damage to the phone. There is a potential risk for fire.

This vehicle hesitates to a dangerous degree when trying to accelerate from a stop or rolling stop. When pressure is applied to the gas pedal, the vehicle will not accelerate until nearly a whole second later. This delay in response has created dangerous situations where merging onto a road in a predictable and smooth manner is crucial (i.e. turning right at a red light, a 4-way stop). I did not notice this problem during my test drive, but now at almost 10,000 miles, the problem has become more pronounced. No warning messages in the gauge display. The vehicle has not been inspected by police, manufacturer, or insurance representative.

Visual Red Triangle code illuminated on the instrument cluster with the number 1 on the side of it. I used my OBD2 reader (Blue Driver) to retrieve the 8 AIR BAG codes. They were B1511 ,B1513, B1378, B1382, B1346, B1481, B14AE, B2618. Problem resulted after the Cowl Cross Bar Assembly (Unpainted), also known as a CRASH BAR, was replaced because of broken welds. It was replaced with a Painted Assembly that prevents access to secure ground for the Air Bags and Seat Belts. The Assembly is used to provide support in case of a crash and also serves as a grounding bus bar for multiple devices, such as; Air bags, seatbelts, Instrument cluster, on board safety cameras, lane, backup warnings, etc...
