Hi all, need some advice- Let me preface this with, I am not trying to get anyone in trouble nor an I trying to throw anyone under the bus. I just want my Colorado fixed. I appreciate anyones feedback as I explain the story.
2018 Colorado LT, 4x4, 30k miles....

About three weeks ago, I had an appointment at my local Chevrolet dealer, which is a very large dealer in the Dallas/Fort-Worth metroplex. The truck has a very weird sounding, only can be described as an intermittent, yet ANNOYING and LOUD squeaking/rubbing sound coming from what sounds like the front of the truck. I showed up to my appointment, and the service advisor and I went for a ride, and he said that he could barely hear the sound, but I was able to hear it as clear as day. He also pointed out that he heard it when we accelerated, and when we braked. Nothing when we were coasting, not using the brakes, etc. He told me that I would have to leave it with him for a few days, or get there early on a Saturday for his guys to take it in. I didn't have the ability to do that at the time, so I told him I would reach back out in about a week or so.
Fast forward a week - I was to be traveling so I was going to leave the truck prior to leaving the DFW airport. I ran some errands in the morning, and after getting the truck up to operating temperature, It is not making the sound, at all. Unfortunately I did not have the time to deal with this at the time so I went back to my house, and hopped a ride to the airport.

Once I got back, and started my routine I noticed that the noise is still back and I can still hear it as loud as day. I made an appointment for 8:15 AM on last Tuesday. I showed up at 7:30 and they got me checked in. We took it for a ride around the lot, and the service advisor heard the noise. He got me right in. the shuttle took me to work. About three hours later he called me and he said - and please bear with me, I am no mechanic and my terminology may be off - "There was a seal in the transfer casing that was rotted..we fixed it, blah blah..and now it is not making the noise, OH, and you need an oil change. Want that while you're here?".

Hopped an uber back to the dealer on my lunch and drove back to the office. Everything seemed fine. I got out of work around 5pm that day and went to the grocery store, sure enough, the noise is still there, and louder than ever. I am getting frustrated at this point. I reviewed the work order only to find out that it mentions nothing about fixing anything, only that the tech could not duplicate the issue I described.

At this point, I am very hesitant to go back to that dealership, so I reach out to some other local enthusiasts for a referral, and I make contact with someone who works at a dealership about 30minutes south of where I live. I was to stop by Saturday morning, and ask for his buddy the service advisor. No problem at all. I stopped in right on time, met with the advisor, we took it for a ride around the lot. Sure enough, there it is! The noise on the stop, and on the go! He heard it, I heard it. But he told me that they won't get to it until Monday because the suspension, front end guys, etc, won't be in. I say OK, Whatever it takes. I also say, hey since I am new to town and need my registration switched, can you guys please do a safety inspection? He says yeah no problem.

Another $35 uber back to my apartment.

Today I get a call. And now, I am being told that the noise I am hearing is the noise of air going into the engine, and it's louder because I have a K&N Blackwing Cold Air Intake system. Which makes absolutely zero sense, since the noise only happens on the stop and go, and it's also a grinding/rubbing/squeaking noise. However, at this point.. I am not arguing. Because I have a short temper and I really don't want to be mean right now. You catch more bees with honey than vinegar.

I'm not a mechanic, but that's the stupidest **** I've ever heard. I have had intakes on all of my cars. There's one on my 2018 ZL1 camaro, no noises like that. I had them on my 2016 SS, 2015 C7, etc.. Never had any issues. The only COMMON issue here is that much like in the past like I've dealt with Pontiac back in 2009, the dealership is using any kind of excuse to not have to do any work at all. (Example - in 2010, broken ball joint on my 2009 g8 gt - they blamed it on my roto-fab engine covers hitting the hood, when in fact, it was a MAJOR TSB..)

So a couple of things.

1) Where in DFW can I go to get this fixed
2) Should I even bother calling the GM customer care number.. because I am SERIOUSLY SICK OF "NO RENTALS BEING AVAILABLE" and having to pay for an uber. It's going to cost me $36 to get to the dealer tomorrow to pick the truck up.
3) Any other advise.

Thanks in advance.

At this point, I would go straight to the top..that being GM Corporate. It’s important to begin a paper trail so you have a leg to stand on. If you have the original air intake, itstall it and see if the noise goes away, this way no one can say anything, or have impact your warranty. Do not bring it to anyone else other than a GM dealer.

Escalate to GM. They should have loaners available for you, and they shouldn't be giving you back a vehicle that isn't fixed.

I'm currently going through the lemon law buyback process, and dealer incompetence has definitely played a role in keeping my truck off the road for 78 days in the last year and a half.

that’s my problem. I don’t have the intake. It’s back in pa.

Should I just call the GM customer service number or is there a better way of Star

DFW is a big area with a lot of Chevy and GMC dealers. Where are you located? It would make it easier to recommend another dealer to see.

No experience with recent service and how much luck you will have, but close to airport can mean a lot of things. (That dang airport grounds is larger than a lot of cities and really splits the region up. )

If northwest of airport, I would suggest Classic Chevrolet in Grapevine. Southwest of Airport, I would suggest Autonation in North Richland Hills.

Those of us who live west of 360 (Fort Worth area for those who do not know the area) rarely venture to the east (Dallas region) if we can help it. There is DANGER east of the 360 split.

I know that Freeman GMC over in Grapevine is a pain to get into the service department and get a loaner. They are always booked up.

You're out of my part of DFW, so I have no dealers to recommend, but remember that any GM dealer (Chevy, Buick, Cadillac, etc.) can work on any GM product since they all have access to the computer service databases of all the GM brands.

I haven’t personally dealt with the service department there but this is where I bought my truck and it was the best buying experience I’ve ever had. I also know someone with very discriminating tastes and zero tolerance for BS who uses exclusively them for service.

If you can get your original intake sent to you via UPS or whatever, I suggest making the truck original as alterations is an easy excuse for any dealer and GM to deny warranty coverage. It does not matter if you have had no ill effects on previous vehicles. If a dealer submits a claim with a note that the air filter system is not GM's, GM will most likely deny that claim and any following claim IF it pertains to the internals of the engine.

Very well could be the intake...


https://lmgtfy.com/?q=aftermarket+intake+squeaking

Tons of results from all different brands about that.

Your truck is much quieter than the other laundry list of loud V8 performance cars you named drop above, they are much harder to hear vehicle noises than something quiet like these trucks. Sounds like it is a pretty faint sound that you are hearing much louder in your head than it really is. Similar to the V8-V4 squeak in the fullsize trucks, it isn't that loud but some people make a mountain out of a mole hill and make it sound like it is a blow off valve from a 1,000 hp supra. Finally it makes sense it does it on accelerating and decelerating as that is when RPM's change versus the mostly static sound while cruising. Up shifts and down shifts change the pitch which it does while speeding up and slowing down. Also once the intake is warm stuff expands or contracts when cold so how it fits changes. Lots go in to it.

It may just be a quirk you have to live with, like the ticking from DI engines. I don't think the dealer matters as much as the service advisor and their corresponding tech they have a relationship with. Honestly some of the best service I have had was at James Wood in Denton. Good luck with either identifying it and getting it fixed or living with it.
