2018, 2500HD, Silverado, 4WD, 6.0 Engine, Reg Bed, Extended Cab

I've been a loyal Chevy owner for a long time. Have purchased 4 or 5 new Chevy pickups since the early 80's. Nothing but perfect reliability up until now. Maybe a water pump here and there, but nothing like this. Just retired, purchased another new Chevy. Getting ready for lots of travel. Not happening with this one, now I'm afraid to drive it to down to the grocery store.

Truck has been in for engine failure 3 times:
1st time -  1 Failed lifter and broken rocker arm 3/28/18 - 678 miles
2nd time - Multiple bent push rods, broken rocker arms, and failed lifters - 4/17/18 - 976 miles
3rd time - Oil Pump Failure, Metal found in oil pump - 8/16/18 - 3408 miles

The oil pump went out on a trip from California to Colorado. Got 900 miles into my planned 1000 mile trip and was stuck in a trailer park for 6 days. Never did make it to my bucket list destination.

From what I have researched, generally this 6.0 engine is pretty much bullet proof. Not this one. I believe this particular one has some underlying lubrication system issues. Pretty darn rare for lifters to go bad on a new engine. Multiple lifters....unheard of. Metal in the oil pump....not good.

My fear is that this engine is now compromised. It may run OK for a while, but what about 10 - 20 -30K down the road?

I asked that the engine be replaced when it went in the second time for lifters. GM would not approve it. After the oil pump nightmare I started a case with GM Customer Service. Asked for engine replacement or truck buyback. A rather slow and painful process so far. The rep I talked to is more concerned about reimbursing my expenses while stuck in the RV park. My main priority is to get a new engine or a new truck. That concern seems to be secondary to him and he keeps telling me to contact my Customer Experience Manager, but hasn't told me who that is, or how to get in touch with them.

Not very happy at this point in time. I hope GM comes through with the new engine or a buy back. Seems like the new engine back in April would have saved them money in the long run. Certainly would have helped them retain a loyal customer. Not feeling so loyal to GM right now.

Thanks for allowing me to vent my frustrations. Maybe someone on this forum or some of the other GM truck forums that I'll be posting to, can offer some hope, or advice, or share a similar experience and what steps they took to resolve it.

 

To be fair, I'll certainly follow up this post with the outcome. I hope it has a happy ending.

Lemon Law. Check your state for what qualifies and follow it to a T. Consider a Lemon Law attorney who normally get paid as part of the settlement so no up front out of pocket expense. Been through this myself in Florida and I can assure you GM is not your friend and will fight you all the way. Good luck.

Sounds like your the 1 in a million with this motor. Manufacturing defects do happen and this is what warranties were made for. However your lost time and the frustration you feel can not be compensated for.

tell him you appreciate what he is trying to do but that you would like to speak with his manager.  let his/her manager know that the only thing that is going to put your mind at ease over this is to have a completely new engine put in or be put into another brand new truck.  The 3 major/critical issues you have had with less than 5000 miles on the thing should never have happened and you have lost complete faith and trust in this truck and that the manager would feel the same way as well.  See how that goes.  Just keep it polite and professional though.

I'm going to try that route. Thanks for the advice.

I contacted GM Customer Care multiple times for various issues on my truck, none as severe as yours, and they were entirely unhelpful. I found the best way was to contact a Lemon Law firm and to let them handle things. These firms will only accept cases if they believe you can win and there is no cost to the consumer. My recommendation is to contact them, unfortunately, GM does not seem to care until they receive a letter from a law firm. It is still a long process, but it actually yields results. I'm not sure about CA's Lemon Laws, but I would think you are a perfect candidate to be covered under it.

Thanks for the replies and advice guys. Still trying to work it through GM. I'll give them a little more time to make it right. Not real hopeful. I'll update if anything moves in a good or bad direction.
The GM customer service guy is the most frustrating. Not sure if they train them to be that way or it is just incompetence. Very strange experience.

Have you tried posting in the HD section to see if any other members have a similar problem since this is the 6.0?

Where was your Colorado bucket list location? Just curious. 

Was on my way to Salida to ride a dual sport motorcycle event. Ended up 100 miles short in Montrose. I did get to do some riding west of Montrose, nice area.

Update, GM has assigned a new Customer Service Rep. She is, at least, a much better listener than the last guy.
On the way home from Colorado the oil pressure seemed low. It is at the dealer for that problem now. They tested it and the service rep told me there is a 90% chance I will get a new engine.
Stay tuned....

Hopefully my final update.

My dealer called me yesterday and said my truck is ready. I was quite surprised, because I'm still working with GM Customer Service on a buy-back. The dealer's service rep said "Really?... we just completed the install of a brand new factory fresh engine." apparently the two don't talk.

They found the oil pressure was 4psi, the cam bearings were shot, and the block was damaged beyond repair. I'm guessing where the cam rides.

So...I'm happy. New engine runs fine, and is much more quiet than the old one.

I'm supposed to talk to the GM service rep on Monday. I guess I'll tell her .... never mind.

The Service Dept guys at Jimmie Johnson Chevrolet in San Diego did a great job... Thanks!

GM / Chevy came through with the right fix....but what a painful process.

      2012 Sierra 1500 AC issues

      By Fishbones · Posted

      I just started having AC issues with my 2012 Sierra. The symptom is blowing warm air on all vents.  Here is what I have checked so far. Compressor clutch appears to be engaging and cycling  I checked all fuses and relay, no issues. The only thing I have notices is the short line that comes from the firewall is very cold / frosted. This line is approximately 12 inches long. The coldness stops when it hits the first line connector. As far as AC compressor - At first start the clutch engages, runs continually, Short AC line frosts up. After idling for several minutes the AC line thaws out some but is still cool and the compressor clutch starts cycling on and off every 5 seconds.  Any suggestions on what to look at next would be appreciated.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Unless you are using a bypass filer system with a Beta of 1000 at 2 micron the commercial filters we have access to, even the very best of them, are poor at the 5 to 10 micron range the typical UOA test can 'see'. Point is there are some truly awful filters being sold A 45 micron Beta 75 filter is what Dyson used to call a screen door on a submarine. That leaves wear metals disconnected from filtration unless particulates are larger than the test can 'see' and yet captured by the filter...which is its job. If that is true then you have a major issue screaming at you.    The graph isn't mine. It belongs to GM and their study on this area. I looked up those studies and provided those SAE tech paper addresses multiple times. Machinery Lubrication displayed it and confirmed it. So if you have doubts about the study you'll have to take it up with GM Engineering. Just like you would have to take up a difference in opinion about the meaning a word with Webster or the length of on inch with the National Institute of Standards and Technology.      Most manuals have two schedules. "Normal Service" and "Severe Service". On it's face it tells you that oil in severe service is more highly stressed and doesn't "Last as Long". The item to bore in on is LAST...what does that mean?    It's the same question one asks about how long to toast bread. What are the inputs? Bread type? Wattage of the toaster? Distance from the elements? What is your preferred level of done?    So lets paint this with a broader brush. Oil is made up of the base and the additive package. The first is altered by heat and oxygen and later is sacrificial with a finite life subject to inputs toward that end. Resistance and supply.    It is the reason an OEM's OCI's are determined by 1.) the specifications of the recommended lubricant and 2.) risk management toward the bottom line. Those lubricants are also subject to cost effectiveness for the OEM.    There is a tendency for most people to believe that the OEM recommended oil rest on the top shelf and that anything other is lesser than. Truth is there are more oils on higher shelves than those on the lower shelf below the OEM's. They make that choice on COST TO THE OEM. Testing is incidental to the margin.    GM makes MONEY, the car/truck is a TOOL to leverage MONEY. Insert whatever car brand you like. Until you forking over a million plus COST not quality is the driver. Thus it is by DESIGN the recommended OCI's and oils fall well short of 'best practice protections'. Proof isn't hard to find. GM Ecotec I-4 2400 breather system and cold start PCM tuning has killed more motors and resulted in more litigation for those that used the 'recommended' practice than GM could bear. What was their response? SHORTEN THE OCI. TWICE.    I don't know how long to leave oil in an I don't know how the oil will respond to MY circumstances and because I don't and can't blanket statement or anecdotal evidence my way out of it.....I TEST and FIND the right OCI for the oil I CHOOSE. There is no shortcut but there is blind allegiance. I don't blindly trust anything.    People hear the word 'detergent' and believe that in the context of oil it means the same thing as laundry soap... Only in the most rudimentary way. It's the first additive to give up on you and they are putting less and less with each new API standard. Solvency can be used but it cost. Some unique undisclosed chemistries can be used. Valvoline R & P in example. OEM's haven't an interest in anything they see as limiting market participation. Whatever.

      By KARNUT · Posted

      For some unexplained reason my father wanted a salvage yard. As we were getting the family business off the ground one brother ran the salvage yard. We gathered there when rained out working on pipelines in the eighties to pull parts. Perfectly good running vehicles would come to us simply because they wouldn’t pass emissions inspection. We were able to swap parts and sell some of them. I got a clean old nova with a bad engine. I pulled a perfectly good small block out a Camaro. A father and son project with a rebuilt engine. The son couldn’t get the engine running right. The problem was the spark plugs weren’t gapped. The 90s vehicles probably widened the gap of shade tree do it yourself engine repair. My do it yourself hot rod repair stopped at the 70s. After that my trusted mechanic kept them in running shape.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      I have an old dental chair in my shop. Something I got for free and apparently it has more than scrap value? People collect them although mine isn't restored or anything. It's visually interesting (1930's Ritter) which is why I like it. And it IS decently comfortable if you kick back.   When a good buddy of mine saw it he said, let me guess, Atlas. It's a conversation piece? As in, you ask the questions, they do the talking?   Where do you hide the jar of teeth?   I would never.

      Are we talking about the same thing, though? The 7 versus 3 wear metals was from Lakespeed's 3.0-specific oil brand comparison test between AcDelco oil and Mobil ESP. The filter remains a constant so whatever excess particles the AcDelco oil is producing aren't being filtered out.   I'm assuming there's a parallel comparison to be made; IF the filter can filter down those particles, engine life increases, and your graph makes the case that a better filter (lower micron rating) can increase engine life. Introducing fewer particles AND filtering those particles with higher efficiency is the best of all worlds. Good oil, good filter.   Where we may disagree is the "baseline relative engine life". I'm more apt to believe the base engine life value is 200k+ on very average oil and filters, "bulk oil of unknown brand and white-label generic fleet-grade filter, Jiffy Lube"   Going from a 10 micron filter to a 5 micron filter should boost a base 200k to 275k in a vacuum as a single factor alone.   Here's the whatabout: How does regularly changing the oil and filter ahead of recommended schedule influence baseline engine life? Most people aren't going to science the heck out of this stuff or ask about Micron ratings, HTHS, or wear comparison tests at Jiffy Lube. Most of the Jiffy lube techs would say they need to call their tech support line to even try to get an answer.   --   Because we love anecdotes here, when I was fishing for 4.3 parts at a local yard this weekend, ALL of the 4.3 vehicles had well over 200k. I love looking at odometers of junked vehicles. How far did THIS go before landing at the crusher? The ones that still had engines weren't seized. None of them were vehicles I'd consider were Amsoil queens, in fact most of them had some kind of service cling-sticker in the corner of the windshield indicating it probably had very average maintenance services. Even the fresh parts rigs- I'm not sure taking an S/T series to 400k has much value considering the running value of those vehicles was probably somewhere around $1,000. 25+ years is a good run on time alone.   The intake manifold I salvaged had clean and bright pool areas. As expected, I found the fuel lines in the manifold rubbed through, just like mine. I'm guessing the lines on that donor truck started leaking, the truck started running rough, and its owner said that's enough I'm unwilling or can't take it out of service for several days, or spend $1000+ to repair it at a shop, it's simply time for a newer more reliable vehicle (or, more than likely, this is the 2nd, 3rd time this has happened in the truck's lifetime). While I don't count on my Blazer for reliability, the thought of giving it away for parts at certain points during my adventure, and being mentally free from its needs has has crossed my mind. I'd be losing $1500 or so, but I can only make more money; not time.
