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.

Initially experienced a strange minor revving of RPMs up and down when I had sustained pressure on the gas pedal at highway speeds. The gas pedal slowly became less responsive and, after a short time, I lost all ability to accelerate the vehicle and needed to pull over on the shoulder of the highway. The sudden loss of acceleration was a clear threat to safety. Luckily, I had the car positioned in the right lane of the highway, so getting over to the righthand should was easier than it could have been. No warning lights showed up on the dash. The vehicle underwent a "perfect" multipoint inspection at my local Hyundai dealership the day before the incident with no identified issues. The vehicle is now back at the same dealership for diagnosis. It is likely a critical failure of transmission or software. The car only had about 26,300 miles at the time of the incident. The contact stated that after several times, the dealer was able to identify the issue but not the cause of it. The dealer submitted a warranty request to Hyundai to get a new transmission.

My vehicle started to hesitate as I merged or turned. Then my car completely stopped but it was still cranked. The dealership stated it was transmission issues but no warning lights came on.
