Remote Starting issue or not

[BCGM]

Hello GM

I will now post this here as I did not know there was this thread . I have a 2024 Chevrolet 2500 HD Custom 6.6 Gas engine built  in Oshawa

When starting the truck remotely you can here the initial startup as any vehicle would start but right at the very end  of the start and engaging there is a strange noise it is very hard to describe but it is different . Some are suggesting this is the purge of air from the oil pump and the start of delivery of oil to the engine .

Can you verify if this is in fact what is going on  ?

Here  is a video of another truck with same noise as my truck  

Thank you !

If you have air in your oil pump, your engine is on borrowed time. That should NOT happen EVER.

 

What that sounds like to me is the starter spooling down from a high RPM coupled with the drive gear retracting back into the starter. Stuff like this they used to take the time to engineer out of components ... but these days that kind of quality is a 20th century relic, so this is what you get.

 

The sound reminds me of those toy cars I had as a kid that had a flywheel and spring inside - you would rev them up by pushing them along the floor until you heard that flywheel spinning at a high RPM, then you could let the car go and it would shoot across the floor at 20 MPH, launch of jumps, smash into furniture and walls.

 

There was a point where you could get the RPM of that flywheel so high that it would go FAR out of balance. The whole car would make that exact sound, and the high RPM would bleed off SUPER fast due to the imbalance. Sounds exactly like what is going on with the starter. Just my educated guess anyway.

Okay having said that is this a normal noise ? 

Did you happen to see JR's explanation as to what he thinks is going on in my 2 other threads . Of course I'm not trying to stir anything up here between opinions I just want to know what is going on with the truck

I honestly have no idea. These days I don't work on anything built after 1994. Based on what is shared with me from those still in the industry, this is par for the course - noises, rattles, ticking, etc..

 

Probably better posting that in the 2024 truck forum so fellow owners can chime in with their experiences. This section doesn't get as much eyes on it.
