2020 Hyundai Venue Power Train

I've owned this car since October 26, 2022. I noticed that my gas pedal is spongy and doesn't want to go or after I've stopped for a stop sign or a light. It was only happening every so often when I first got it but now it's happening at least once a week. My local CarX, whom I've been taking my vehicles to since 2013 and have a great relationship with, has looked at everything and can't find a cause. They told me to file a complaint to see if a recall is in the works for this transmission.

I started noticing what I refer to as a "lurch" when driving. It happened a few times when I was driving around 35mph, so I thought I was imagining it. Then when I was driving on the highway on 4/14, I felt like I could not accelerate. When I looked at the tachometer, it was jumping between 2 to 3, and as it jumped, the car lurched. This past week I have noticed this same feeling of not being able to accelerate and the tachometer jumping multiple times followed by the car lurching forward. It happens almost every time I drive. It sometimes happens after I make a right turn. Yesterday it happened after a left turn and I momentarily couldn't accelerate past 11mph before it lurched. No check engine light is on. I took it to my mechanic and thinks it is my transmission. I am scared I won't be able to accelerate when merging on the highway, or in the middle of an intersection, and that I will be in an accident. I have an appointment to take my car to the dealer on Monday (4/15/24) for them to run diagnostics.

I was driving on the highway around 65mph. I saw my RPM gauge going up and down from 2k rpms up to 4k rps and the vehicle was jerking. The car felt like it was going to turn off. The vehicle RPMs spiked all the way to 7k RPMs and the car started to lose power. I was able to get to the shoulder lane by the grace of GOD. I turned the car off for about 5 min. Once I started the car and put it in drive, the car would not move at first even though I pushed the gas pedal all the way to the floor. I was able to get the car to drive slowly to a safe area. I took the car to a Firestone and a Transmission Shop, and both said I was having a Transmission issue and should to the vehicle to the Hyuaindai dealership. This is very unsafe.

After I stopped at a light or anytime I hit my breaks then the gas paddle the motor vamped up like I was racing.I was at a stop light when the car would not go. I jerked the stick and it finally like a bunny hop for an out 100 feet and then smooth sailing.there were no other warning signs but I parked my car I thought was too dangerous to drive. Looked on i internet and there were several complaints. But no recalls were issued. However when I reported it to the dealer it was a confirmed recall.I have now a brand new transmission. Don’t know if the dealer saved it for inspection. I think I drove the car for at least 3 weeks and thought I was hitting the gas paddle to hard until the car stopped on me at a very biz.intersection.
