Turbo Failure

[NEVADADSL]

Well I had a CEL (P0234 Code Turbo Boost) a couple of months back on my 2021 Sierra 1500 Elevation with the LM2, and it took that long to get it into the dealer. Just got the call that the turbo bearings are going out and it needs a new turbo. This at 26K and change. Thank God it is under warranty. Dealer says they do see this happen but not that often. I love the truck but this makes me quite uneasy.

Wow, that is low mileage on a turbo.

I had the same thing on my 2021 LM2 at 10K miles. 2 weeks at the dealer to replace turbo. Haven’t had an issue since. 28k miles now.

Thanks for the update.

Before I shutdown the engine on my '24 RST 1500 LZ0 3.0, I always idle motor for about 3 minutes, especially after a long highway run. This helps lubricate and cool down the Turbo bearings, and dissipates excess heat, thereby prolonging bearing and Turbo life. When shutting down the motor I believe the Turbo is still spinning hot without any lube, and by idling the 3 minutes the turbo gets a chance to cool down. My Dad's old '66 Mack truck had a metal plate on the dash that said, "Idle 3 minutes before shutdown".

It was common knowledge to idle diesels down after pulling.

But then the damn epa and carb came along and it disappeared!

 

[Denny56]

Not sure what you mean, but I am assuming they don't like the Diesels to idle because of excessive exhaust emissions?

 

[gemarsh]

Yep, that is it!

Could have been a turbo that was over looked during inspection.

I never shut off the engine if the EGTs are above 415-430 degrees. For those w/o a gauge, letting the engine idle about a minute or so will get you there.
