23' Lz0 - loud bang while driving and metallic chirping / sqeaking at ilde?

[CarbonProLZ0]

Ok. This thing has been a pita in the last few months...

23 lzo bought new (1000 dealer miles) and curren5ly has 49k.

Just did a trans service, dealer warranty work to include: fuel pump module, front seal and oil pan gasket. All within a few k miles from the same dealer that I purchased and have serviced the majority with.

Was driving 55 - 60mph when a bang was felt, like someone hit me in the rear, followed by a loss of power and metallic chirping or sqeaking. I pulled over and shut it down.

Currently sitting for a tow. GM fought me about towing it to the dealer that just did all the work because it was 3 miles outside of the 25 miles. Lmao. What a joke. Pretty disappointed in GM. Truck is babied.

Anyone have a stab? Thrust bearing even though its a '23?

Got time to kill, humor me lol.

Edit: I will add NO CEL at the time I shut it down. But I did it rather quick.

Sounds like the tranny dropped to a real low gear (someone hit me from behind).

That is what was first reported, that started the whole 10speed fiasco. The tranny would drop to a lower gear locking up the rear axle at highway speeds.

gm re-wrote software that once the computer detected the bad spool valve, it would not allow to shift above 5th gear.

Rythmic metallic chirping / sqeaking after. No movement, just at idle. I moved it off the road after I called the dealer. It did start and move on its own but didnt feel right at all.

Was dropped at the dealer this afternoon. They have it in thier system to diagnose tomorrow. We shall see....

Its too bad these trucks have so many issues. Im not expecting a perfect vehicle but the issues have been plenty for ta new 70k vehicle. Shame. Im a Toyota guy and thought I dodged a bullet with not buying a tundra, now not so sure.

I'm thinking bad valve body? Maybe improper fill procedure when they serviced it last. Could be lots of things. And unfortunately you can't buy anything new and reliable anymore in the 1500 platform. Gotta go 2500 gas for semi decent reliability.

I should have seen the writing on the wall when the "chrome" peeled off the grill at 10k miles. Lol.

If the refresh was out when I was in the market I would have bought a 3/4...couldnt see spending all that money in '23 for an immediately outdated truck.

Life has its ways I guess.

Every person that has had a tundra with problems says the same thing you are. Ive never met someone or talked to them on the internet that has had car problems and doesn’t say the same thing. Internet has allowed us to magnify anecdotal experiences. We definitely have problems with these trucks but so does everyone else buying other vehicles from different makes. I hope they get you back together and you have a few hundred thousand trouble free miles.

I appreciate the well wishes.

Unfortunately, have too many people close to me that have issues with these platforms. Most issues are common amongst the models and drivetrain respectively.

Rose colored lenses never helped anything, I agree.

Update: #1 rod and bearing are toast.
Needs a new motor.


I find this interesting because it just had wet gaskets done...no oil change since...what are the chances some gasketing came loose and plugged up an oiling port?

I treated this thing like a baby. No reason this thing should have grenaded at 49k miles.

I'm not surprised. GM has so many issues between the thrust bearings on these baby max engines to the trash 6.2 failures. Transmission failures left and right. The only two reliables are the 6.6 gas and the 6.6 dmax - when you remove the communism from your truck that is.

Anything is possible, but I'd say highly unlikely that gasket debris was a factor. It would have to bypass the screen on the oil pump pickup tube, grind up going thru the oil pump, then having to bypass the oil filter and finally not starving the camshaft bearing first.

You do have warranty, right?

 

[gemarsh]

How many miles since the pan was dropped?

There should have been glitter or gray sludge in the corners of the pan if it was very recent that the mechanic should have seen, replacing the pan gasket.

When you say bang, I'd say it threw a rod. A rod bearing going bad would show up first as a double knock for a bit, ~50 miles or so and then getting worse. But with Dino piss oil viscosity, I don't have any experience with, I'm OG.

Yes, its the 3.0 so its 10y-100k im pretty sure for the powertrain.

Now dealer is saying cylinder #1 in an email. So idk. All I know is it got mechanically funky in the motor.

Only reason im asking is because from my quick research this is kind of an odd failure.

Oil changes were done at factory intervals at the dealer. Everything was fine until it was opened up for the gasket stuff. Then the fuel pump module went a few k miles after that. Then this two weeks / 600 miles after the FPM was replaced.

Id have to check, but within the last 5k. They told me about the leaks and the warranty work at the last oil change. Im due for one again. I dont know if they change the oil after the gasket job or not. I would assume they did but lol...the world we live in who knows.

It went like this: Bang, then sqeak / chirping youd expect from rod / bearing issues. The classic. I knew it as soon as I heard it. Motor didnt like it, immediate drop in power. It ran for less than a minute while I pulled over. Its a busy 2 lane road with each direction doing 60mph +/-.

My first motor failure. Ive had a few vehicles and do 90% of the work myself....unless its a new one under warranty...go figure. Lol.

I just shake my head and throw my arms up every...single...time... I read this crap.

I know the babymax is new to gm, but gm has been...producing...a... [email protected].

You'd think they'd have it figured out by now!

They have the mark up figured out.
They are trying to squeeze too much efficiency of these motors in my opinion. At some point, between efficiency, power, and reliability, one has to go.
