If you are shopping for a used Chevy truck, make sure you check out this list of 2023-2025 Chevy Silverado 1500 known problems.
While not every truck will have an issue like seen below, you should be aware of the possibility and what is currently going on with Chevy Silverado 1500 trucks.
The information presented below was collected from NHTSA.gov complaints, recall information, various Facebook groups and online forums plus experience from covering the industry for the last 15 years.
6.2L V8 Engine Recall and Failure
At the time of this post, this is currently the hottest topic surrounding the Chevy Silverado 1500.
Currently, there is a recall impacting 600,000 2021–2024 Chevy Silverado 1500, GMC Sierra, Chevy Tahoe, GMC Yukon and Cadillac Escalade vehicles equipped with the 6.2L V8. These engines can completely fail due to “connecting rods and crankshafts with debris in oil passages or out-of-specification parts” according to NHTSA.gov documents.
Federal investigators have expanded a probe on this recall twice now looking at older models and now a new probe is looking at models that have had their engines replaced.
A big part of the controversy is GM’s fix is to switch to 0W40 weight oil from 0W20 for those engines that pass a test to see if they are good or not. Simply put it is a mess.
5.3L V8 Engine Lifter Failure
Another topic that comes up from time to time is lifter failure on the 5.3L V8 engine.
These lifters push on the pushrods to open the intake and exhaust valves in the engine. If they fail, you can loud ticking noises, the engine will misfire and you’ll have power loss.
This seems to go in batches with people posting about it for a few months then nothing for a while. I’ve personally spoken with a variety of dealerships and mechanics on it. Some rarely see it and chalk it up to not doing proper maintenance and others say it is a rampant issue.
At the forefront of the issue is the idea the cylinder deactivation system is causing the lifters to prematurely fail due to excessive use. The current 5.3L V8 uses a Dynamic Fuel Management (DFM) system (2019+) that replaced the Active Fuel Management system aka V8 mode to 4 cylinder mode.
The DFM system can shut down cylinders more rapidly and can have the truck run one just one cylinder at a time when you may be cruising downhill without a load. There is no indicator light on the dash.
Whether it is true or false that this is directly related to lifter failure is up for debate (trucks built during COVID without DFM had lifter failure as well), there are aftermarket solutions to disable these systems.
3.0L Duramax Diesel Thrust Bearing Issue and Coolant Control Valve
Another engine issue for GM has been recent and not so recently affected the 3.0L Duramax diesel engine. This is the fuel economy diesel returning mid-20s and even into the 30 MPG range for full-size trucks.
First, last October, I broke the news of a thrust bearing issue causing complete engine failure. This was just starting to happen in dealerships and we were seeing dealership technicians talking about it online. GM issued a service bulletin to test the engine after an owner asked for the test to be done. No recall. Many engines were replaced and I’ve only heard of one failing in January of 2026 since then.
Second, coolant control valve failures were pretty common for owners of 2021-2023 Silverado 1500s with this engine. This caused check-engine lights and the possibility of engine overheating. GM issued a special coverage (N252508340) for 2023 models only and provided free replacements for that part for up to 15 years/150,000 miles.
Why only 2023? Your guess is as good as mine.
Lastly, not really a known problem, but more of a known maintenance item is replacing the “wet” oil pump belt in the rear of the engine at 200,000 miles. This belt is considered wet because it circulates in oil. The issue is you’ll need to remove the transmission to get to the belt. It is really best done at a dealership and isn’t a cheap replacement item.
8- and 10-Speed Transmission Woes
GM transmission woes go back for years now. They seemingly have had issues for as long as I can remember and the 8-speed was especially troublesome.
Here’s the deal. The 2023 Silverado has the older 8-speed transmission that customers say has harsh shifts from 1-2, delayed engagements from park to drive and shudders. There’s a class-action lawsuit on that one.
Some customers have swapped out the transmission fluid to Mobil 1 synthetic and they say that’s fixed a lot of those issues.
The 2024 Silverado, only available on the 2.7L Turbomax 4 cylinder engine, has an updated 8-speed transmission that’s more believed to be more refined and revised versus the 2023 model. I haven’t heard nearly the complaints with the 2024 model like I did with the 2023 and older.
Then, let’s talk about the 10-speed transmission. This was co-developed with Ford and has had its share of problems including a rear-wheel lockup issue last year leading to a new valve body design (aka the brains of the transmission) being replaced.
The timing of this recall was especially bad since GM and Allison decided to call off their branding partnership on the 1500, 2500 and 3500 models at the end of 2025 with dealerships pulling down advertising by the spring of 2026. People associated the problems with the 10-speed to the ending of the brand partnership.
Going back to 2019, GM had Allison badges on trucks, but the transmissions weren’t built by Allison. It was a distinction the media reported on, but many consumers didn’t get the memo.
GM and Allison continue to partner on medium-duty trucks like the 4500, 5500 and 6500. So, take that how you will.
Ultimately, what do you do? Take the truck for a test drive and see what you think of the shifting.
Electrical and Infotainment Issues
The final issues I see are mostly related to electrical and infotainment issues. This mainly has to do with dash lights coming on unexpectedly and cell phones not connecting.
These issues are often either a small issue like a fuse or a random part failed for the dash lights coming on.
Cell phones not connecting is a common problem for all brands. This is often resolved with either updating the phone’s software, the truck’s software, turning off the phone completely and restarting it or buying a new phone.
The 2023 model was refreshed and runs a Google-based operating system which seems to have fixed a lot of the connectivity issues for many consumers. But there is always going to be a problem with an older device or user issue connecting to the software.
