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...

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...

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...

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...
