Stinger problem

[Michael brown]

I have a 2018 kia stinger v6. It has 37k miles I was driving and lost some power at 3000k rpm, and the car studer and the check engine light came on. I went to Kia and they said one of the spark plug was bad so they changed all 6 plugs but the problem persist any ideas ?
They replaced the spark plugs and now same thing happend again , now they tell me two of the spark plugs cracked again said they will be changing the coils next

I've got a 2018 Stinger as well approximately 39000 miles I had the same type issue dealer ended up replacing a coil pack, I'm guessing they didn't check the plugs because I just recently changed them and one was cracked

Picture of the crack plug I pulled out, this was middle plug on driver side

The number 5 and 6 plugs cracked on mine the ceramic. So now they are going to replace the coils.

I have a 2018 also. Spark plugs and Computer replaced - problem solved.

What computer? Are you saying they replaced the ECU?

What computer? Are you saying they replaced the ECU?

Yes. That was in 2018/19. Covered under warranty. No issue since

Hey Rob ,
Have you had any problems with your fwd collision warning not working , I enable and disable that option still does not work, any ideas ?

 

[Robs GT]

Have you had your front bumper off anytime recently? Maybe the connection they on the driver side has become loose, otherwise I'm not heard of this

 

[Michael brown]

No have not removed the front bumper no work done there , guess I will have to consult with Kia
Thanks

I have a 2019 with 82,000 so might catch you next year Gunner Like everyone else, I also had the spark plug issue at about 45,000 miles and the dealer replaced all coil packs and spark plugs with no issues since Overall a very solid and dependable car. My goal is 300,000 miles, so guess I will see if it makes it.
