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

      Silverado 4500-5500-6500 are they still being produced? Would have sold better as GMCs as well

      By C/K Man · Posted

      There was talk over the last couple of years that the contract to build these trucks between GM and International would not be renewed.  International moved production of all their other trucks besides the companion CV model out of the Springfield plant some time ago when they opened their San Antonio plant.  That left Springfield only building the Silverado Medium Duty, International CV Series, and some Express/Savanna long wheelbase cutaways.  International also put the plant up for sale some time ago.  This all answered my earlier question as to why GM and International did nothing with these trucks since they were introduced, as they had basically become a market 'placeholder' with a finite life.    The Silverado Medium Duty/International CV trucks were interesting combination of a GM powertrain, electrical system, and K2XX Silverado cab with an International chassis that was supposedly designed for a step-van type vehicle they never produced.  They were manufactured in International's Springfield plant along with the IH MV series initially.  When first introduced, there was much talk that the Silverado Medium Duty/CV would eventually get a gasoline engine option along with other upgrades and GM and IH would work on a class 6/7 joint venture truck.  This was before VW bought Navistar out, after that happened no more was said.  Draw your own conclusions...   About the time talk started that the GM/IH joint venture was not going to be renewed, rumors started that GM would develop a new line of medium duty trucks themselves.  The story is the new trucks will be part of the next generation HD's due in 2028, and will still feature a 'straight rail' chassis design that the current medium duty has.  GM views this as a desirable feature that differentiates their truck from the competition.  A gasoline engine option is also expected.  As the current Silverado Medium Duty remains in production until September 2026 and there is still a lot of inventory available do not expect any official word for some time.   I believe GM remains committed to their successful partnership with Isuzu, and all the LCF models will still be available from Chevy Commercial dealers.  Isuzu is on the cusp of opening a new large plant in South Carolina and there is also speculation that this may result in new product for both Isuzu and Chevy Commercial dealers.

      Software Update

      By nfisherman · Posted

      I have a 2026 2500 HD Ultimate. My phone app says there’s a software update available. It’s something about improved battery management and something to do with the running boards. I follow the instructions for the update but the “Check for Updates” option is greyed out in my settings menu. Has anyone else seen this? How did you resolve it? The help message just says “see your dealer” if the download doesn’t work. I’m just trying to save a trip.

      Exhaust Question

      By newdude · Posted

      Fuel mileage?  That's all how you use your right foot.  Exhaust will give you sound.   Stock exhaust 5.3 is 2.75" diameter piping.     If the truck is nice and worth putting some $$ into it, I'd go for a Corsa catback.  I had one on my 2019 old body 5.3 and it was just perfect.  Zero drone, just driving around and cruising on the highway you'd think it was stock, but when you opened it up it was like a Camaro with the factory dual mode.  Corsa bumps their catback to 3in diameter.
