Check Engine Light On problems of the 2015 Hyundai Elantra

When I try to accelerate quickly, especially if the engine is still cold, I will suddenly not be able to accelerate even though the engine and vehicle is still running. Then when I slow down the vehicle begins to shake like it's almost going to die altogether. Then if I try to accelerate again, it's almost like there is no power to drive,or the engine completely stalls, and the check engine light begins to flash and the oil pressure light comes on. The only way then to be able to keep driving is if I completely stop the vehicle and turn the ignition completely off and wait a few minutes and then it will usually take 3-5 tries to get the car to start again. This happens nearly 1-3 times a week, and the dealership says that it's not related to the engine recall that they issued, even though it appears to be the same exact issues that is affecting the other vehicles. There have been at least 20 occasions where I was trying to merge onto a highway and then my vehicle dies or loses power and this is a huge safety concern of mine.
