Engine was misfiring last week, so I brought it to the dealer. They confirmed that I had a collapsed lifter, and that it had to be replaced under warranty. When going over the repairs with the service writer, they informed me that they only replaced the failed lifter. Out of curiosity, I asked him what such a repair would cost outside of the powertrain warranty. He told me it would cost anywhere between $3500-4000 if it happened again, and that all of the lifters would need to be replaced should I be paying out of pocket. He added that I would be "silly not to replace them all" due to the type and magnitude of service, and because of the likelihood that another fouled or damaged lifter could fail shortly after the first. GM only authorized the dealer to replace the single failed lifter in my engine. I drive for work, and already have 45,000 miles on my 2016 Sierra. I am happy to let GM replace as many lifters as need be on their dime. That said, as the end of my 60k mile powertrain warranty nears, I am worrying about long term reliability on this truck. I have maintained it meticulously. What are your thoughts? Since I've had a lifter failure at such low mileage, are there high odds that another will fail on me soon, or at all? Should I dump the Sierra and get another 5.3L? Would a Denali with the 6.2L be more reliable? The styling and interior of this truck have made it my favorite vehicle ever, so I'd hate to see it go.
Yikes. I've got a lot of these issues with my 2016 Sierra 5.3, amongst so many squeaks and rattles. Haven't gotten much better treatment at any of the three Chevy/GMC dealerships in my area. Maybe I should take it to the Cadillac garage
Same issues with my 2016 5.3 Sierra. I've read in one post that the rough idle is due to buildup on the fuel injectors. Another post says it is due to the low idle RPM, and that it can be fixed with a tune. Either seem likely to me - mine happens right at 500 RPM. Who knows what the dealer will tell me. Probably that it is "within GM spec" or that they "can't duplicate the problem." Of course, they'll tell me that at 5:50 PM, after keeping truck all day.
I hear you dude. I have a number of issues with my 2016 Sierra SLT 5.3L: Shake at highway speeds Engine vibration at idle Rattling center console Rattling rear sliding glass I've got 24,000 miles on the clock, and I'm seriously contemplating dumping the truck before the warranty runs out. What really gave me pause was test driving a 2012 Yukon SLT for my fiancé. The Yukon had 90,000 miles on it and drove more quietly and solidly than my new truck. Like you, I've gone through all of these issues with all 3 Chevy/GMC dealers in my area - none of them have been permanently fixed. Still trying to decide what to do with the truck. I'd hate to see it go - the styling is gorgeous inside and out - but I am getting tired of driving around in an expensive rattle box that is constantly in the shop.
I'm definitely trying to get the ball rolling on this mod. I have a few questions: NIXONRIDE, what year cluster did you install in your 2016 SLT? The link you shared in another post was for a NOS 2015 Yukon XL Cluster. I'm hoping this is what you had Chris White program, as it would be much cheaper than buying one new from GM Parts Direct. 2015 Denali Yukon XL Cluster ($200.99) - http://www.ebay.com/itm/2015-Denali-Yukon-XL-Instrument-Cluster-OEM-23249954-New-/231754299431?fits=Year%3A2015%7CSubmodel%3ADenali&hash=item35f5a1f827:g:lKsAAOSwdvpWDtS4&vxp=mtr New Cluster ($604.67) - http://www.gmpartsdirect.com/oe-gm/23249954 Since Chris says that the clusters must be correct for the body year, my thought is that I'll have to purchase from GM Parts Direct. Are you having any issues with Apple Car Play? Does the cluster Navigation work?
Mine doesn't seem like it will come out. I have been pulling on it and it won't budge at all. There is a tiny bit of play, but it seems to me that this one cannot be removed by the customer. Frustrating.
