Anyone experiencing a slight dash rattle in their 2019+?  Feels/sounds like its coming from the centre around the defrost vent or possibly the sunglass holder but I doubt its that piece.  I'm having a hard time pinpointing where it is exactly coming from.

 

The rattle has basically come out of no where, no noticeable rattle/sounds prior to the last few weeks.  It is winter now and it is damn cold up here in Canadian prairies, but other than being parked outside during work day its parked in a heated garage the rest of the time.  I suppose it could be the cold, but like I  said i can still hear it when driving to work after pulling out of the garage after driving for 20-25mins

 

Anyone dealing with the same or hearing the same and able to tell me where it is coming from/the fix?

Yea I have a rattle in that same area.  I tried to locate it by putting pressure on different parts of the dash with no luck.  It changes with different temps as some days there is no rattle at all.

Mine was in the dash as well and I took it into the dealership and they had to relocate the transmission harness because they have had a few T1s with this issue. He also stated that a couple of the screws holding down the center console were loose and he put loctite on them so they wouldn’t  come back out. Haven’t heard any rattles from dash since.

Yeah exactly the same, have not been able to pinpoint it, and it comes and goes based on temperature it seems.  Makes me wonder if its simply just expansion vs contraction of the plastics

Not sure the trans harness would be my issue, but the screws would make sense.  I'll have to see what the dealership thinks, and I may just wait until it gets worse (hopefully not) before taking it in to ensure they actually can fix it and not give the "couldnt replicate what your talking about"

That’s why I drove when I got to the dealership and took him for a ride. I went over ever d@mn pot-hole and railroad track I could find. He noticed it and I told them don’t give it back till it’s fixed. They took about a week.

Its related to cold temps.  I could duplicate it by pressing in a certain area of the defrost grill to the left of the light sensor. Somedays it would make the noise and other days no noise at all.   There is a 7mm head screw located under there that can be removed and it will lessen the noise.  I removed the screws one at a time and retested. I think it was one just to the left of the light sensor.  My noise was more of a creaking/etching type noise

This is my fear lol.  Thinking this might be happening to me in the near future.  In process of getting the wife a new car, so after that this becomes my next priority.

This makes sense to me.  To clarify, popping out the defrost grille and the screws beneath is what you are referring to?

Its more of a plastic on plastic etching noise and yes, below the grill

Mine seems to happen in relation to the engine.  Doesn't really happen when idling then it happens a little gets worse around 1000-1500 RMP then goes away.  But not always.  It's very random but annoying!

Yours might be related to the wire harness or the fuel/evap lines contacting the floor pan.  There is a pi available for this concern

What is a pi? And where can I find the harness or the lines?

I have a slight vib/rattle to the right of center dash. It only does it just coming off idle and only when it's first started.  After about 3 to 5 minutes it goes away.  Idle no rattle, light throttle input rattle, RPM goes above 1000 and it's goes away.  I don't get the vibration on deceleration passing said RPM range only when accelerating.  Makes me wonder if it's exhaust related and once heated tolerances change enough to make it go away.

My wife's 2023 Chevy 1500 is making this awfully annoying rattling sound. Coming from the center of her dashboard sounds like middle dashboard inside. She has a full bumper to bumper warranty but chevy says to open the dash it will be $1500. Anyone have any help for us?

I had a rattle that I thought was coming from the centre of the dash or a piece of nearby trim.

Turned out the drivers side sun visor was against the clip, but not snapped into the clip...

      Bench seat swap for 2021-2024 suburban

      By davester · Posted

      probably won't get a response from that user, as they haven't returned to the site since making that one post.  users don't (at least I don't, and I haven't seen any setting which would notify me via say, email) get any notification other than going to this site, and checking if they got a response on their thread...

      Wow I'm in a pickle. (Broke down truck) and a story.

      Thanks - I wasn't quite caffeinated this morning. 2:1 makes sense, turning the crankshaft 360 degrees will turn the cam 180 degrees, and had I done that, the cam's dot would be at 6 and the crank's at 12 again.   I went ahead and took the sprocket off anyway, aligned everything dot-to-dot including the balance shaft just for s&g. I'm glad I did because I discovered no Loctite on the timing sprocket bolts. Maybe it's not required, but at only 20 ft-lb torque spec, those bolts aren't in there very tight. Cleaned and reassembled with some thread locker and torqued.   A general observation: Less is more with RTV. If a little doesn't stop a leak, a LOT probably won't, either. RTV is thinly veiled revenge, in a tube...

      The timing marks are ok, that is #1, you can turn it over until they line up and it won't change anything, the crankshaft turns twice for every camshaft revolution, I have always set up SB Chevs as your pic shows using a straight edge

      Someone's been here before.... There is a receipt for a 3-piece timing set, purchased earlier this year.   Is this picture something, or, nothing?   I have the timing cover off and my crank is perfectly TDC and the keyed gear's locating mark is dead on 12 o'clock.   The cam gear locating mark is also at 12 o'clock. Now, I'm not an expert, but all the install guides say the two locating marks should meet and be perfectly aligned when installing a timing set. The mark on the crank should be dead on 12:00 and the cam gear's mark should be dead on 6:00, and both marks should be perfectly vertically aligned.   I believe the timing gear is keyed or has a dowel that ensures it can only be installed on the cam in one position, so I have to believe the cam is out of phase somehow. At the very least, with a triangular bolt pattern, it can only be installed in one of 3 different positions.   Before I pulled the front cover, the truck was running alright, no service engine soon lights except an occasional P0172 / rich condition. Timing -16 timing at idle (should be +16), and total -35% fuel trim, two conditions I haven't been able to figure out.   In related news, my injector tested pretty well, wasn't leaking, but I had it rebuilt anyway, and it's on it's way back to me.         Along with this discovery, the good and bad:   Good: The oil pan seal appears undamaged.   Bad: -The timing cover has been reused, and the positioning dowels have been broken. That could explain some of the leaking. -Some kind of white paste or grease was used to try to seal the oil pan seal and timing cover (since wiped off..). -Then, someone globbed silicone all over the front of the cover and also buried the ckp sensor in it. But, they didn't put any inside the cover or use RTV to try to seal the oil pan seal with the timing cover (good).

      PF63 Oil Filters Going Away?

      By Grumpy Bear · Posted

      The guy that owns K&P filters last I checked in with him has over 300,000 miles on his Dodge base Hemi using his own 35 micron absolute stainless mesh filter from its first oil change.    The GM study I've posted a dozen times shows the relationship in engine life based in multiples of base units, not miles or years. That is the base unit is the number of miles the motor ran using the reference filter efficiency.    The above two paragraphs dismantle anecdotal arguments IF one changes oil often enough to prevent particle formation and the motor is in otherwise good shape. That is not full of silica (no air filter) or suffering a metallurgical issue that is not part of the lubrication discussion. Poor heat treat in example.   Data from UOA's I've reviewed from more than a few engines can show remarkably broad variations in oil cleanliness using the exact same filter over the course of an engines life.     Lastly there is the common sense of it. Wear debris WILL circulate the engine BEFORE it ever sees a filter in route to that filter and WILL harm the pump which NEVER sees filtered oil.    Alpha question then becomes, given the facts, how long do you believe is a reasonable service life from a vehicle you are certain you will not pass down? That is the junk yard will be it's resting place when you're done with it? (the moral issue most don't care about).    Omega question is then how diligent are you prepared to be in general mechanical, air & oil maintenance? Preventing particulates and keeping them sufficiently dilute; preventing the precursors from generation, amalgamation and precipitation.    If I get a good look at the engine bay of a vehicle I have a fair idea of the owners commitment to the inside of the power train. That 30 micron WIX is still more efficient than a sieve.
