Truck makes Loud Bang. Check Engine and Codes. Found Turbo Pipe Burst

I was driving on a Tollway today on cruise control me and wife heard loud POP or BANG. Sounded it came from the front of the truck. Thought I had hit something, but I didn't. Instant power loss but truck running just acceleration is slow.

Two messages appear on dash display:
1) Service Electronic Throttle Control (Red Lightning Bolt)
2) Service Electronic Stability Control.

Thought maybe and ECU or other module had failed. Drove back home with just slow throttle response. It felt like it had lost any turbo boost.

Got home and inspected under the truck and found no leaks or smells. Opened the hood saw some oily residue on the air intake pipe from the filter. Took off the engine cover and found the Turbo feed pipe before entering inter-cooler had burst. Then saw something funny sitting on top of the engine block. A roughly 2-3 inch metal sleeve. When I looked at where the pipe had burst. It DID NOT look like this could of been thrown from the tubing assembly. The tubing was partly together and I couldn't see how this ring could have been shot out of the pipe. I just had the 01A HPFP recall done on my truck about 11 days ago. Is it likely the servicing mechanic forgot to reinstall the metal ring weakening the tubing?

Check for codes as well and got a bunch:
2022 RAM 1500 3L V6

~11,500 Miles
P0299 Turbocharger Underboost
P2471 Exhaust Gas Temperature Sensor Circuit High Bank 1 Sensor 4
P00101 Mass or Volume Air Flow Sensor "A" Circuit Range/Performance
P049B EGR "B" Flow Insufficient Detected
P0266- Cylinder 2 Contribution/Balance: No Sub Type Information

I'm taking it in to Ram service tomorrow, since it is still under warranty. I've attached pictures of the interesting particulars. You can clearly see the metal ring sitting just below the burst point. Notice the tubing still seems semi together.

Thoughts? Anyone else seen this before?

I took mine in for the HPFP recall about 2 weeks ago.
I got the “Service electronic throttle control” message cleared the code and 2 days latter loud noise loss of power. I pull the engine cover and notice the turbo down pipe broke off.

- Loud noise from engine area.
- Multiple error codes on dash.
- Immediate loss of power.

All of that and you limped it home before taking a look? Granted you probly didn't hurt anything here in this case but my only thoughts are you got real lucky there wasn't a different issue that you made much worse but trying to drive home in a wounded vehicle. You should have pulled over immediately to at least get eyes on the situation.

You got lucky, both in not making things worse but in that you are still under warranty. As long as they are paying the bill, hand it off and let it be their problem. Sounds like a possible mechanic screw up that should be easy enough for them to fix.

Thanks for the comments!

I didn't say in my post, but I did pull over and look at the situation. I didn't see any visual indications of a problem. The engine cover hid the obvious problem, but I didn't have tools with me to check it out. Truck restarted just fine after my inspection.

The truck is in the shop, expecting a diagnosis tomorrow.

I really want to know where the ring goes. I have my theory, but I'll wait for confirmation before commenting.

Wow, sounds like the same issue. Did you see a metal ring laying around as well?

Just got my truck back from service. They did not have a replacement turbo joint tubing in stock. Since it is a low failure part it is on back-order and expected in 15 days. The service technician used a similar strength tube cut to fix the problem.

Seems to be back to original power and no codes have popped back up. I'll baby it until the proper replacement is installed.

Remember that metal ring I mentioned, it goes in the plastic end of the hot side pipe to prevent distortion when the clamp is tightened.

IMHO, I believe the ring wasn't reinstalled during the recall fix and the clamp was under/over tightened resulting in the blow out. I have no proof but be forewarned just in case you get the HPFP service. Check for the ring after completion.

I have the same truck and had this exact problem yesterday. I was towing my travel trailer, heard the bang and had loss of power and the throttle control and stability control error codes. Camping weekend ruined. I've owned this truck for a month and driven it less than 3,000 miles (it has 23,000 miles on it) and already making a trip to the shop. Very disappointed.
