2025 Hyundai Sonata

The vehicle is stalling in the acceleration process. I can feel and hear the stall by the air conditioner going out or fading out when it happens while driving. Pressing the gas and it barely moves at times. Makes a noise now while running. Unknown to whether it's electrical or engine or transmission. Pull out in the traffic accelerating but the car wasn't moving at the pace it should have. Could have cause an accident when trying to cross on going traffic. Just got the vehicle 2 weeks ago. No one has inspected the vehicle yet. Going to have it looked at for recalls. No warning lights appeared to reflect an issue, but there clearly is.

the car has two issues. brake issue (gas pedal is soft and sinks) and engine power ( gas pedal is soft and not responsive) Brakes are soft and spongy some times and sometimes hard. even you push the brake pedal twice or three time it takes long distance to stop. some times the brake looks good but for short period of time. the brakes inconsistent. I took to the dealer where I bought it hey refuse to repair it. then i took it to another dealer. first time they said no issue with car then second time they they replace the vacuum pump and they found out one of the piston is not firing. they replace the ignition coil. the car still has issue and not fixed. I filed case with the manufacturer but the manufacturer closed the case. After that I file lemon law case.
