2017 3.6L Cold Start, Engine Noise, Rod Knock, Rattle?
Hey forum peeps,
So my 2017 Colorado, as well as my 2017 Canyon, both with the 3.6L v6 and both with 800-900 miles on them, makes a very strange noise on a cold start up. I tried searching but only came up with 1st gen stuff.
Anyways, on a cold start up in the morning or after the truck sits for more than maybe 8 hours, ( I am in Florida) it sound like a nasty rattle, cam chain, rod knock, sort of sound. I usually use my key fob to start the truck and I can always here it for a few seconds almost as if there is no lubriation...
So I just went to the dealer in the colorado and had the oil changed and it still does the same thing. I grabbed the keys to 2 different colorados on the dealers lot and both did the same exact thing. This may be totally normal but normal, mechanical train of thought tells me otherwise.
Have any of you had this exact problem? Maybe it is only an issue on the new v6 for 2017? I want to say that it almost sounds like an exhaust heat shield rattling but the truk makes ZERO noise other than cold starts.
I can try and take a short video for you guys and upload it and maybe it'll give you a better understanding of the type of noise. I am not sure how the quality will come out though from my cell phone.
Anyhow, thanks for any input on this. I appreciate you helping me brainstorm. I asked they dealer and they told me "Oh yea totally normal" before I could even tell them the make and model...lol I hate them so much.
