No need for a response like this. First warning. Next you'll get some time off... OK?

Been on active on multiple car forums for 17 years now, that's is one of the weirdest responses I've ever seen.

The problem with those sites and others like them is that the majority of people who respond are those with issues. GM puts out nearly half a million of these trucks per year so that is about 2 milli

2015 All Terrain 6.2

Developed the dreaded tapping sound on left side of engine.  Push rod on #7 cylinder was bent and valve lifter stuck open.  All valve lifters on left side replaced as well as #7 push rod.  25701 miles on truck and 12.5K miles later no issues.  However it did convince me to purchase an extended warranty from James E Black Cadillac.  Had been changing the oil and filter every 7000-7500 miles, after engine work went to 6K max between oil changes.

I have a 2014 5.3 with a 110k on it.  So far nothing for motor and transmission other than regular maintenance.

I’m at ~135k on my 2014. Only major thing I’ve had done was had to have the AC condenser replaced at 58k and 130k. No engine work at all.

2016 SLT 5.3L @ 85K No engine work never been opened etc.  AC compressor failed while back......just wipers,tires,brakes windshields etc.  Usually go 7-12K on oil obviously not worried about me's pushrods.....they are actually very stout v8's get you one!

75K on my 2014 5.3 V8 and no issues with the engine. Small stuff like AC condensor around 60K but the big kicker was my lovely transmission went out at 73K miles 4 months out of the 5 year 100K warranty. Otherwise trucks been good

My Torque Converter went at 120k miles, required a complete rebuild of the trans.

Have you gotten your trans flushed yet? TC is a known issue with the 2014 and 2015 models.

172k and still going strong on my 2015 5.3.  I change air filters every 40-50k, 7-9k oil changes, did plugs at about 110k.  I also fogged the motor with Sea foam at about 100k.  I also force the system to stay in v8 mode by keeping the trans in 5th gear.

 

Hoping to hit 250k with this one.  Shouldn't be an issue. 

 

Replaced entire A/C System at 130k

Rebuilt Transmission at 170k

 

Other than that just brakes and other preventative maintenance like fluids for transfer case, differentials, greasing here and there. 

 

This truck has been cared for, but it's also been put to work hard almost daily.  I'm very impressed with the overall quality.  People seldom believe it has the miles it does, especially after seeing interior.  I keep it clean but nothing fading, ripped, broken, ect.  Cloth interior.

2014 GMC Sierra K1500 5.3 V8 - Purchased new August 2014.  Build date in June, 2014.  Only work so far:

 

At 30,000 miles or so CEL on three separate times over a two week period - always code P050D - no other code.

 

Dealer replaced all 8 fuel injectors.  All covered under my GMPP extended warranty but the $200.00 deductible.

 

Truck is getting better mileage around town and on highway.  By my calculations at least 2 more mpg.  Engine also sounds quieter.

 

Use Mobil1 0W-20 Advanced Fuel Economy Dexos1 Certified oil.

2014 Double Cab 1500 LT, Z60 5.3, 6L80E

Needed regular oil changes, air filter, cabin filter, front brake pads and rotors and shocks at 100k. AC kept shitting the bed. Otherwise a good truck. Headlight bulbs around 90k.

2017 Crew Cab 1500 LT, Z85, 5.3, 6L80E

Oil changes, air filter at 50k, diff change at 50k, at 67k now and not a single major problem. AC is different from my 2014 and seems much better. I do have a catch can on, but saw no issues on my 2014 related to oil and carbon buildup.

Seems like a good truck, these K2s. I don't have much bad to say.

How many miles now on your Ecotec's 4.3 5.3 6.2? Please state any engine work/repairs done and estimated miles?

 

40,000 New plugs is all for me! Only because I am GDI ****** is why

 

 

 

Are these engines more reliable than FERD'S you tell me.............

122,500 miles with my 'normal' maintenance only. I did replace the VLOM supply screen and pressure switch at 75 K because I wanted to. Just me being curious. Both were perfect upon inspection. Kept the switch as a future spare. Standard 100 K tune up. Plugs and wires. Cleaned the MAF. None of it needed doing. Lowered the thermostat to 170 F what, two years ago? Want to, not need to. Again me being me. Replaced the plastic starter shield last fall when it warped ticking on the flywheel ring gear. Nuisance noise. Is that more reliable than a FERD?

Most likely it's been more reliable than a FERD.  From now until 200k is where the GM powertrain and FERD show their true colors.  FERDS are nice to look at but not a contractor grade truck for 1500's imo

      DTC P2C48 auxiliary cooling pump

      I tried tapping it.  This might sound like a dumb question, you should feel vibration or some type of noise when it turns on? Can someone please verify? Thank you all!

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      I feel better now for my own view point and actions or lack there of towards the dealership service theme reading your post and others. GM corporate is who offers the two free oil changes on the HD trucks and I bought my truck in Feb of 2025 and those oil change offers run out within 2 years I believe and I highly doubt I will be using either one of them. I had asked if I could officially give those free services to another customer ( a friend ) and they said no, its all a GM corporate thing based on the vehicle in question. What that service advisor did however was go into a little story about how such and such customer was denied engine warranty because he had done his own oil changes because then they are not documented ... you see where that goes and so an employee playing the game of scaring the customer into having the service work done there most certainly triggered my thought process. At a later date I did talk to the person who handles warranty claims at the dealership and she said to be sure to document the oil changes and keep receipts for the oil and filter ( coped the receipts from cases of Mobil oil and case of filters I bought from them ) and the vehicles VIN, the date of service, mileage etc and staple that together as a record I would give them if that was ever needed and I keep my own log book for services for each vehicle as well. Oh and about 8 months after I bought the truck the dealer starts calling me to offer a maintenance service since they haven't seen my vehicle show up on their system ... for the mere fee of 300.00 Canadian to change the oil and rotate the tires and a few other minor checks and I declined the offer, I get the call again a couple of months later for the same thing and she could tell I was not interested and she asked if they should take my name off the call list and I said yes, do that !.    By the way did you happen to keep your factory oil filter to open it up and see the surprises inside as I expect some will show up as per the odd little sliver of metal shaving and particles that the filter does trap along with bits of grey silicone sealer that come off of the inside edge of mating surfaces. I have cut open every filter so far on my truck although few miles but have changed the oil often and the second filter was vastly better with very little of anything, that first filter was the unsettling one as I expected it would be.

      I get why they do this…but man…not ideal. I only extract on inboard boat engines because the drains are buried and even then I hate it because it’s easy to leave a quart behind with that method.   They should market it as an “oil refresh” not oil change!

      I only get oil changed where I can watch. Valvoline pulls through the dipstick into a see thru glass. When done they show me the dipstick. About the only way they can mess up is using the wrong oil. But that secret wouldn’t stay secret long. Honda uses TQ wrenches on everything. You can watch through a plate glass window. Discount tires does that with tires. Trust but verify.

      I would not argue that with you. It would be pointless to argue against the truth and you speak the truth.    My question and in fact the entire point of this thread is an exploration into the levers of wear which happens no matter how well we maintain our powertrains.    Some of these levers we exert a good deal of influence over which can and do result is lower wear, longer powertrain life. Some others we are sort of stuck with.    An engine is typically done when the ring to bore seal no longer is able to do the job effectively. Normally the first thing to go in a engine otherwise well maintained and adult driven is this seal.    Looking into the means, methods, products and attitudes that influence the rate of wear seems a worthwhile inquiry to me.
