What's the worse that could happen (turbo fins mangled)

I also posted this photo on Facebook (if it looks familiar). My 2019 Colorado is brand new (about 300 miles now) and the turbo has been whining pretty much the whole time (it was raining the day I drove it home, so I can't say for sure if I heard it then). This truck replaced my 2017 that GM bought back under the Lemon Law - that one didn't whine at all (this is my 5th diesel vehicle so I'm familiar with the sound of the turbo).

I decided to pull the intake hose off to check to see if I had the bent vane problem I've heard a lot about (it didn't seem likely, since it doesn't freeze here and the truck is brand new). And found this mess.

The service manager said he thinks it's fine to drive it, since the noise hasn't gotten any worse and it has been happening for at least 200 miles of driving.

My question: Do you all think it's fine to drive it like this?


(Clearly this should be covered under the warranty - I hadn't even opened the hood until I popped it to take this photo. But the service manager said something about how they'll have to take a look to "see how this happened". But they can't look at it until Tuesday.)

I'd be looking for a loose bolt or screw. It IS mangled.That thing had something it tried to suck into its innards.

Holy crap... That's the worst I've seen. Any cats missing in the area??

I would not drive it. There's bent fins, then there's mangled fins. I think when you look at how fast that turbine spins, the chance of a failure that creates far more issues is much higher. But I'm not a mechanic, and if he says you can drive it...

Wow that definitely had a nut or bolt get in and bounce around for a while.
I would drive it but easy.

So I wonder how many turbo failures that were thought to be ice were actually a nut or bolt or something else left in there after assembly.

Ouch

Are you seriously asking if that's okay to drive??? Hell no. Quarantine that thing. Demand a tow and a loaner car, all costs covered. Show the service manager that picture if they question anything.

Worst case scenario, bits of aluminum get sucked in through the intake and you trash the cylinder walls/rings/valves on your brand new engine. Looking at the shavings already sitting there, I'd request they send a boroscope in all 4 cylinders to make sure that hasn't already happened.

No, I would not drive this.


It is obvious that pieces of the blades have been broken off and are now all over the intake.


You best hope that the inter-cooler stopped them from getting into the cylinder heads, if that happens, well could score the cylinder walls so now you are looking at a new engine.


When turbo is being replaced they will need to clean out the whole system to make sure no pieces left. and I would watch oil consumption like a hawk now.

At least now we know where Sharon dropped that quarter on the assembly line.
And no, dont drive it. Id insist they checked everything downstream and replace anything affected.

If I was the tech. the intercooler would be replaced also. You can check the fins in it to see if something is temporarily stuck in it. Thatís my 2 cents.

Do not drive with your turbo looking like that.

It's a brand new truck fresh off the lot. Had you not opened it up to look just for fun, would you still be driving today? Service manager says drive it, they'll take a look. While it's definitely not right, internet paranoia says park your new investment immediately the world is coming to an end. What about for the tons of others on the road driving right now that have no clue their fins are bent/damaged? Drive the truck as you otherwise would have intended for a brand new vehicle purchase. Take it to dealer when your appointment is scheduled and let them decide. While yes it sucks, it's covered under warranty and you're in better position than anyone to get it repaired properly under warranty as it's so new and unmolested/modified.

Best of Luck,

Mike

Being ignorant doesn't make it any less of a problem. That's called gambling.


Park the truck and contact the dealer. Capture everything you can in writing for CYA.

Do not drive it. That is not the bent fin from ice that has been shown here on a few trucks. That is mangled from a hard object that was either dropped in intake post filter on assembly or maliciously from disgruntled employee at PDI dealer. .
If it were me I would demand a new truck because this is just purchased, and the turbo looks to have lost chunks of metal that have been blown into intercooler and possibly beyond.
If it were a bent fin like the ones that were affected by ice, I would say to keep driving it ( as some have done with no issues), have turbo replaced and carry on, but this is completely different. But, bolt ,screw, something was left in the intake and you should not have to own this truck.

Hahahahah. Nice choneofakind. If you're happy with gambling and sub par work then go ahead and stick your head back in the sand. Try thinking big picture here and take a look at dmaxjr reply, see if that makes any more sense. He is 100% spot on correct. OPs turbo does not appear to be a bent fin from piece of ice. That thing is trashed. You paranoid folks stop driving that and tow it to dealer and dealer does his best work to replace the turbo. Great- you just got your turbo replaced. If you're happy with that, I feel bad for you. There is obviously metal that went elsewhere downstream in the engine from what is missing on those fins. Drive the son of a bitch til it blows up and the dealer takes it back. That way you're getting it fixed right with either a new truck or engine replaced rather than just the turbo. I would expect the damn thing get fixed, and fixed correctly being brand new off the lot with 300 miles and a big loan pay off looking like that. A turbo swap is NOT the right way to fix that thing. To think otherwise is foolish and a gamble I'm not willing to make.

Best of Luck,

Mike

What's the worst that can happen? Problems and headaches and a shortened engine life, with GM and their dealer shining you on.

Something hard fragged that turbo, and metal bits were force fed into your engine at 22 PSI. Not the stuff one wants to have in their new 40K vehicle. If it were me there is no way I am keeping that truck. I would be a PITA, via legal action if necessary, to get the dealer to take the truck back and provide you with another one, or a refund. Absent the dealer taking care of me, I would get the turbo replaced under warranty and get rid of the truck.

Assuming I was dicked around by the dealer, I would also post that fragged turbo photo, name the dealer, and drop a negative PR nuclear bomb about how they dicked me around on every online outlet I could find. Alec Baldwin said it best in Pearl Harbor...

Go to another dealer.

I had 1 bent fin and my dealer immediately put me up in a loaner until the turbo could be replaced.

If you are still in warranty, they should tow it to the dealer at cost to them and furnish you a loaner car, and if they do not have one, make them get you a rental car at cost to them. Almost all dealerships, have Enterprise Rentals in them. I would be worried about what did it, and more so where the piece went/ended up. Are you in an area where it could have been a chunk of ice?

Looks like GM should have put a screen inline before the turbo, to protect against this.
