2012 Denali with 30k miles, Motor Needs Replaced

[GAFan]

Hello,

I have a 2012 Yukon Denali with approximately 30k miles. I purchased the vehicle brand new and we have never had any prior mechanical problems with it. We were in the process of loading our luggage into the vehicle to go on vacation when I noticed a very loud pinging, knocking noise coming from the motor. It sounded like someone was inside the motor with a hammer. We ended up having to borrow another vehicle to drive to the beach and we had our vehicle taken to the GMC Dealer. The service manager has called and states it appears the motor needs to be replaced as it sounds like a rod has broken inside the motor. The service manager is waiting on GM to give the authority for engine replacement vs rebuild. Has anyone heard of any engine issues with the 2012 Yukon Denali? It has been babied and driven by wife mainly around town. I was in disbelief when I got the call from the Service Manager indicating the motor needs to be replaced with such low miles.

Not common obviously.

However anything can happen.
It is a man made piece of equipment after all

i remember that same call on a 1998 S-10 i bought brand spanken new like 7 miles on the odometer when i left the lot
and by 9000 miles right after its 3rd oil change the lifters started tapping real bad because it was out of oil when i took it to the dealer and they ran a compression test and found one of the cylinders had literally no compression so they called and were informing me they were either going to replace the block or rebuild the motor

Thank you Jennifer.
It was actually one of the service advisors that contacted me.
I am really surprised more than anything about the motor issue.
I have sent you a PM.

That's crazy. I'm on my 4th GMT900 and this has never happened. Hopefully you get a new motor from GM for free

Very, very, very unusual. Looks like you are under warranty anyway. That is what it is there for- please let us know what you find for posterity.

 

[GAFan]

Will do. Thanks

Sorry for the headache you have had to deal with. To share my story, I've got a 2008 LTZ Avalanche with a 6.0L motor, 106k that was weeks away from trade-in. Slowly I started to notice a similar "hammering sound", which progressively got worse in about a week's time before I brought it in the dealer.

They also initially suggested a motor replacement, but after pulling the motor out they discovered a lifter had gone bad. I elected to have the motor rebuilt with new lifters and camshaft, in lieu of a replacement motor. Total cost was $4,200 and work was done in a week with a 12,000 mile/1 year warranty.

Be thankful you have that warranty and spend the extra cash on really frequent oil changes.

I'm guessing this is a Displacment on Demand motor. Only ones I saw have issues the short time I worked at a gm dealer.

 

[ezdaar]

wow, 4,200$ for lifter and cam swap.

Any update on this?
