Very interesting I think I will do that thenMine was weird. The cylinder would not fire but I could get no engine light. When the engine light came on, after 6 or 7 times, I was able to hook it up to a thing at a parts store. Yeah P0301, cylinder three misfired. I was at Auto Zone, they told me 96 bucks for a new coil. I went home, bought 1 coil off of Amazon for 25 bucks. Took 2 minutes to put in. No more misfires!
P0301 is cynlinder 1 misfire.Yeah P0301, cylinder three misfired.
that sounds exactly like my 2017, 2.0l..Elantra..in my case it was an intermittent # 2 coil pack was starting to fail.. would not show at dealership either, and i told them what it was going by my diagnostic reader, but they did not believe me till the next time i brought nit in and it finally acted up and they replaced it.. couple month later..# 3 fails the same way..14,000 miles.. gotta catch it when its on..good luckHello everyone, I've had my elantra coupe 2.0, 2017 for three years, bought in 2019, it has 71000 km and until two months ago it was working perfectly. In mid-June, while driving on the highway, it suddenly lost engine power, the engine light on the dashboard came on intermittently when I was accelerating, and I had clearly loss of power, as if the engine was in protection mode. The engine was also shaking when I was stopping at a red light or at the stop sign. I took it immediately to the hyundai garage, the mechanic called me back saying that they have no error code and do not know the problem. They drove the car two times and everything went well.... I get it back three weeks later, same thing. I bring it back again, no error code, the mechanic tells me I don't know, maybe an oil change. 2 weeks later, same problem. I can drive the car but the check engine light is intermittent. When you turn off the engine and restart it works again with no engine lights ( so impossible to get a error code with my diag). Clearly I don't want to go back to hyundai, they don't know anything about it, it's very dangerous to have this loss of power like that. I think it must be some sensor because it's intermittent ( air flow sensor or else)? any idea?
Hi everyone, after a month without the problem, it did it again this morning but this time I’ve used my diag device and it says code P0301 cylinder 1 misfire? Thanks for your advice on thisAugust 15th, exact same thing just happened to my 2017 Elantra. I only noticed loss of power when I got off the freeway and was sitting at the light. My engine was shaking also. I wasn't sure I would make it to the tennis courts. It seemed to me like it was a fouled plug. It wasn't idling the way it normally does and when site I accellerated, it was sluggish. After a couple of hours of tennis, site I opened the hood but couldn't find anything except a dirty engine. Got on the same freeway to go home, never got above 68mph here, no engine light and running normally. here Yeah, sounds like a faulty sensor or a fouled plug. I only have 23,400 miles on my here car. site

My 2017 flashed a engine light, they showed a misfire. With no argument they replaced all ignition coils under warranty. Apparently there a service bulletin, "quiet recall" or whatever. The factory coils have some problem.that sounds exactly like my 2017, 2.0l..Elantra..in my case it was an intermittent # 2 coil pack was starting to fail.. would not show at dealership either, and i told them what it was going by my diagnostic reader, but they did not believe me till the next time i brought nit in and it finally acted up and they replaced it.. couple month later..# 3 fails the same way..14,000 miles.. gotta catch it when its on..good luck
