It’s in the starter. They all do it. Nothing to be worried about

have you guys checked to see if its the steering shaft seal in the firewall? Theres a thread here describing all these symptoms.

If it's a tick under load that sounds like marbles in a can, It's the steering shaft boot. there is a TSB for 2017 and newer vehicles

The TPMS from a new style 19 will not work with the older style

Any update on this?

Alignment and tire balance. Then take it from there.

sounds to be coming from the starter

Wire open the valve permanently

If the sound disappears when you turn the steering, like going around a corner, and then reappears on the straight, its likely the steering shaft boot. There is a TSB for the 2017s for this. I really don’t think it’s a predetonation noise or seat noise, if it sounds like it’s coming from under the steering wheel. An alternative solution is to pump some lithium grease into the seal yourself to see if the noise settles down. If it does, that’s your issue.

If this is a marbles in a can sound, with low RPM and the engine under a slight load, it’s more than likely the steering shaft seal letting DI pump noise into the cabin.

I suppose really my question is has anybody disassembled the reclining mechanism and can they give me any pointers?

So I know the clicking issue has been covered and the suggested solution Is to do the hose clamp trick. my issue is somewhat different. I have an intermittent click noise that is coming from the recliner motor area of the seat. I can recreate the sound by adjusting the seat angle via the button, and then get in the back and put pressure on the shoulder of the seat in a side to side fashion. I then have to adjust the seat angle again to make the noise in this way. there seems to be a good bit of slop in the motor as it spins for about an eighth of a second before the seat moves. I’m hesitant to go to the dealership as they already said that they added the retainer, and that’s the fix, but that’s not a fix for my issue. in summary it sounds like an issue with the recliner mechanism, and not necessarily the frame itself. anybody any thoughts on this?

I hear DI noise

I should have added, my click is coming from somewhere from the back of the seat, not the seat area. You can also see below how deformed the retainer clip is.

Mine is starting to click again after 6k.

Super long extensions on my ratchet.

Ok! Do you open the 15mm bolt and completely remove it or just slide it down?

I'm going to have to have a look ar this. I just got a 14 for work and the noise is driving me nuts. 180K Km on it. My 16 has had it creep back in the last 3 weeks. Prior to this I pumped some grease in from outside it. I'm going to try some gm lube on the inside of the boot, and wrap it with some dynamat to see if theres any difference. I'm not interested in going to a dealer with my 16 - too much hassle!!

Pip5570 is also another solution.

Wow. Unbelievable that it was missed.

If you open the door you will see the weatherstrip on the inside. It's just pinched.

Try the grease trick and see if it helps. Then you'll know for sure.

I also used some grease on the inside side of the steering column. Try that
