Anyone have an issue with the 2018 Elantra GT Sport turbo model losing power and shutting down? Car has 20K miles and this issue happened
last Thursday without any warning. Dealer has had it since Friday and they have no answer yet even though it has shut down for them. Any replies
would be appreciated if you have experienced this.

Usually it would be caused by a misfire code, followed by a flashing check engine light. Typically coil packs are the culprit.

Have them check the turbo oil lines mine were not to spec so shifting of the engine would cause limp mode and oil to spray out. That was the culprit on my car. My second culprit was coils that were starting to fail and plugs that were hella dirty and poorly gaped. Have not had any turbo related isues since then.

I'm having similar issues with my 2018 elantra gt sport lately.

First, it started with a persistent check engine light for misfires in cyl 3. After having plugs replaced and engine light cleared, started the car up a few days later in my garage and check engine light came on...followed by it blinking and the engine sputtering and rpm being erratic...tried to drive it out of garage but no power. Took it into the dealership again and this time, they told me faulty ignition coils. Got those replaced and low and behold...after about a week, check engine light comes on again.

This is seriously becoming tiresome.
