5.3L and 6.2L lifter failure lottery
3.0L timing belt behind the engine (150K to 200K mile service depending on the year)
Body dents if you breathe on it wrong.
Some are built in Mexico.
Engine and transmission drive great if 6.2L. 5.3L is known to be underpowered. I've only driven the latter at elevation in a Suburban and it was certainly underpowered there. No experience with the 3.0L, but people like them. I had a 2020 6.2L RST Silverado for four years.
If you're a performance oriented driver at all, the 10 speed is lacking true manual controls and sport mode is a joke. Otherwise, it's very smooth and is pretty quick with the 6.2L. The 6.2L has a lot of grunt that makes it fun to drive at part throttle.
Fuel economy with the 6.2L was 14.7 lifetime but could get 21 on the highway. Premium fuel required in the 6.2L.

Can disable the AFM/DFM for $200 and solve the lifter issue.
That's what I used mine for. It was good for that, just be careful putting stuff in the bed or knocking mud off your boots on the rocker. It dents easy. I ended up pulling the rocker panel dents out with PDR glue and I could actually push the high spots back down with my thumb.TexMexAggie1 said:

A lot of people get away with running regular gas, but I wouldn't do it. The engine detects knock and pulls timing to account for fuel less than 91 octane. By the time the knock sensors kick in the detonation is already occurring, which can cause damage to the piston surface, cylinder walls, and rod bearings. Furthermore, you're losing hp/tq and fuel economy by doing so. Both the Ram 5.7L (89) and Nissan 5.6L (91) recommend higher grade fuel as well. The 6.2L has fairly high compression and some of that detonation risk is mitigated with the cooling effects of direct injection, but it's designed for premium fuel and I don't think that's a bad thing considering it is a premium engine with an aggressive but relatively efficient combustion cycle.AustinCountyAg said:recommended, not requiredaggieforester05 said:

The 5.3 has plenty of power unless you plan to tow heavy loads. If you are not towing all the time, the 5.3 is PERFECTLY fine power wise.

The 5.3 and 6.2 are good engines, but a $200 electrical disabling device does not "solve" the issue. It's a good bandaid, but you have to physically remove the 8 DOD/AFM lifters, physically plug the 8 oil towers in the valley, and retune it in order to actually solve the problem.
The real culprit is the EPA and ridiculous CAFE standards for imaginary climate change and feelz.
The two I have done the lifters failed collapsed. The roller was not frozen on either one. But yes, once repaired it will go 250K+ miles. And federal regulators are a problem.aggieforester05 said:
... The roller freezes up and eats into the cam, sending metal shavings through your oil system.
That being said, once you do the delete, you should have a really solid engine that will go for 250K+ miles with little drama.
Manufacturers have had to sacrifice reliability across the board to satisfy federal regulators and it isn't getting any better anytime soon.
To piggy back, any recommendations on who or where to take it to get it done in Houston area. I have a 23 Sierra SLT I want to do this to.tamuags08 said:

Assuming that completely voids your warranty?
