2017 Elantra Startup Issue. Sign In
Hello, I have a 2017 Hyundai Elantra. This is completely random(probably 2 times a week) other 5 days no issues. When I first start up my car in the morning it runs really rough and would probably die if I didn't tap on the accelerator. After it warms up it runs completely perfect for the rest of the day. No check engine light, no codes from my scanner. Does anyone have any idea of what it could be?

Sounds like it has a misfire on cold startup.

I'd probably start out with a tune up but you may also have a coil or two getting weak.

Have it scanned for codes. There may be some helpful info there.

A failing fuel pump is also a possibility.
