I have a 2017 V6 automatic with 45K miles that suddenly has a noticeable engine knock (never had the typewriter click common in GTs). It has all of the symptoms of a bad engine knock sensor, according to YouTube (knocking, sudden loss of power, bad gas mileage) EXCEPT the check engine light has not come on in the 3 days since I noticed the knock.
The knocking doesn't happen at all RPMs. It's there at idle and very loud during deceleration, but intermittent during acceleration. I'll be honest, I let it go at least 2-3,000 miles past the oil change light this last time. However, I changed the oil yesterday, drove it 60 miles roundtrip to work, and it made no difference in the knocking. I'm also using regular 87 gas.
I've read about the false knock issues. I have everything stock except for a muffler delete (which I don't recommend on a V6) and it's a convertible, but I think the chances are pretty low that this is being caused by a false knock somewhere else.
From what I can tell, the knock sensor isn't exactly easy to change out. The shop said it would cost $110 just to diagnose. I'm wondering if I should bring a new knock sensor with me, so they can change it quickly if that's the issue.
Has anyone else had this issue with a V6? Does the V6 have more than one knock sensor? Is there anything else that it could be?
***UPDATE*** The dealership is replacing the "short block." That's all the service advisor was able to tell me.
***UPDATE*** Finally got the car back after 2 weeks. The paperwork says "wrist pin binding" on cylinder 6. I drove it 30 miles to work and so far she's purring like a kitten.
