Hey Ya'll I am picking up my new 2022 Limited GMC Sierra SLT Crew, 5.3 10 speed next Saturday. Going on road trip right away to test it out. So with this said anything I should be looking for in a new truck with 10 miles on it?

 

Been hearing and reading horror stories about DFM, engine failures, tranny etc on GM rigs. Any input from others with this truck have experienced.

 

Have been GM driver all my life from 61 Olds Dynamic 88, 68 GTO, 66 GTO, to 2006 & 2007 Silverados.

 

Thanks for input.

I wouldn't worry about it. Just drive it, follow GM's maintenance intervals, and enjoy it. Chances are, you'll never have a problem. And if you do, that's what warranties are for.

 

Congratulations on the new truck and have a safe trip.

I wouldn't worry about it either. I've owned a 2015, 2019 and my current 2021 all with the 6.2l and either the 8spd or 10 spd tranny with no major problems. There are many more that have no problems than those that have them. Usually people don't post the good things, only if they have issues to try to get help. There's differing opinions but I personally would take it a little easy during break in period, not sure of the trip your taking but I would avoid long stretches of continuous 70-75mph driving until you put 500 or so miles on it. Just one persons opinion.

 

Enjoy the new truck!

Let her rip!  I've driven cars off the lot and embarked on a 5,000 road trip the next day.  No issues!

Most of the time a trip was the trigger for a new vehicle. Even pulling rigs. 40 years of letting it rip has never failed. Usually the exhaust shop, the gooseneck ball, transfer tank, toolbox. I remember the first V-10 had undercoating. Where the glass packs were  the undercoating melting off from exhaust heat. Fun times. The second V-10 my father power braking on the test drive. Rubber coating the quarter panels. The salesman wide eyed when we got back. I’ll take it was his response. Yea we break them in real good.

Based on the knowledge of engine builders that I have worked with on various autos, try not to keep the RPM's too steady, prolonged driving at a stationary RPM's is not preferred when trying to get the piston rings to seat and establish a good seal.  Despite what many people say, a good quick romp or two on the go fast pedal is not a bad thing and generates the heat and pressures required to make the piston rings form a good seal.  Just don't hang the engine at high RPMs to the point where its bouncing off the rev limiter.  Vary your RPM's as best you can and let the engine get up to full operating temperature before you shut it down.   

 

I know it sounds funny but manually putting your truck into a specific gear once warm, and then accelerating to a higher rpm and letting the engine slow you down, is a good way to break in the rings as well.  It varies RPMS, generates adequate heat and pressure, and is easy on the engine.  The key is to very your rpms and loads, don't let it sit at a stationary RPM for prolonged use if at all possible.

Found this in the Owners Manual for Break In, basically says what I mentioned above:

Probably the same people who wrote owners manuals on proper vehicle break ins. Told us not to eat salt, egg yokes, meat, bacon and drink diet soda. I don’t follow their advice anymore either.

I'm with you for the most part, on most things.  Its probably the difference between being within 99.0% of the acceptable efficiency rating and 99.1% when it comes to an OEM engine.  However, a break in procedure has never made the engine less efficient or less properly broken in :)

To be fair all of those things are relatively bad for you without moderation.

That’s true about everything. The problem was the substitutions were worse.

Thank you to all that have provided input. First drive is from dealership to hotel. Then off for a 350 5-hour trip until next stop. putt around town to see family then another 5-hour 350-mile trip for a tourist stop. Then 8 hour drive next day.

 

All in all, 3K mile trip right after purchase. So will take it easy for the 1st two days and drive like an old man that I am lol.

 

Will post pics once i get of course when time permits.

    • My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.
    • Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken. 
    • Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.
    • I have 2 choices. 
    • Do you have access to BP fuels? Some stations have Silver 91 E-0 priced the same as their 93 E-10.  There is a local Marathon with 90 alky free for $6 a gallon but I go down the road to BP for $5-ish. They also have a 100 E-0 but that stuff is $10 a pop.
