Dual Clutch Transmission (DCT) hesitates when slowing to a stop, then accelerating. The car completely looses power and limps for a second or two until finally it engages and power finally goes to the wheels. Also, the DCT clutch completely failed at 117,000 miles while traveling 65mph on the freeway, and Hyundai won't replace the clutch. Hyundai will only sell a new complete DCT.

Since I've purchased this car I've had problems with the car when moving when stopped. When I first start to drive, stops at a stop sign or red light, the car hesitates, shudders and vibrates when pushing the gas. There is a delay when stopped and then taking off, to the point that I have been honked at while the car just idles before it shudders and moves on. I've been asking about the problem since I purchased the car and have been told it is normal for the sport model or they been unable to replicate the problem at the dealership. The safely issue is that I'm worried I'm going to be rear ended while waiting for the transmission to kick in. No warning lights. Please research this problem and suggest a fix to Hyundai. The delay is also felt when the automatic transmission is shifting in lower gear, no problem once the car is on the highway or straight a way driving with no stopping. Thank you for your consideration.

I've had several issues over the years with this vehicle but nothing too major but more so a nuisance. Such as the car hesitating when accelerating, light bulbs constantly burning out on the vehicle within less than a year of being replaced by myself , etc. It is now April 2022 and vehicle problems begin arising, I heard a weird noise coming from the engine (after much personal research learned this is a knocking sound). Which also happens to be the same issue from the prior year models. One day while out running errands the car just completely dies and goes into limp mode while I was turning onto a busy street (very dangerous). I drove it a very short distance back & forth to work a couple of times because thats as far as I felt going safety wise. The engine jerked forward one day but still continued to run. Then one day on my way home from work when I began slowing down to turn into a driveway. The car completely died again. It went into limp mode enough for me to creep and barely park it where I ended up having to get out & push the vehicle. It doesn't turn over or start at all now. The car gave absolutely no warnings no codes for me to turn to regarding what was going on etc. Hyundai says in order for it to be covered under the warranty that I have to provide them with information. Which I have no problem doing. However based on the research that I've done from other Hyundai Elantra owners others have had similar issues. My Car is barely 4 years old & only has about 65,000 miles on it. I went with Hyundai's because I wanted something that would be safe and reliable especially because I had a child coming into the world at any moment. I ended up going with this vehicle which isn't even 5 years old & it has already become a lemon. Hyundai currently has the vehicle as I try to figure out what to do with it. Since I no longer feel safe driving it. There are no warning lamps etc that came on.
