2019-2021's w/6.2L not involved in the recall

[Blade8971]

As a result of the recall issued by GM on the 6.2 in which 2019's thru to early 2021's that were not involved, I'm curious if the options stated below are being considered by these particular group of owners which I'm a part of as I have a 2020.

 

1. Keep the truck and implement modifications such as a DFM disable/delete and using a different viscosity of oil.
2. Trade in the truck for a new one equipped with a different engine such as the 3.0L or 5.3L, or go for a HD version.
3. Trade in the truck for a new one from another manufacturer.

My 6.2L 2019 AT4’s extended warranty just expired 3 weeks ago and I’m currently going between option 1 & 2. I’m leaning heavily towards 1, deleting the DFM and running either 5W30 or 0W40. Mostly because I own the truck outright, don’t tow enough to justify a 3L and I still love the thing plus everything new is so expensive.

Number 4. Pay it off keep it for a spare. Then buy another.

number 4 is just stupid. it really depends on if its paid off and mileage or do you like throw away money. i would go with number1. number 2 is not an option, buy newer tuck and most likely you will get a 10 speed which has its own problems. unless your willing to go withe 2.7 and 8 speed , it seems to be GM's most reliable power train for now. number 3 is a crapshoot, ford is no different than gm right now as they are having to also replace a lot of engines. so every manufacturer is having problems. if have money to throw away do what you want to do, if not stick with number 1

Interesting response. I’ve done that multiple times. I always have a vehicle available with 10 floating around family members. Especially if you buy CPO you get great deals. The nice addition is if I don’t want to drive a p/u I have choices. Your choice is modify it. Then hope it’s done right and risk being without a ride. My way has served me well.

Trade it for a 2.7L Turbo 4.

My situation is similar as my powertrain warranty expires in a few months, plus I finished paying off my loan last year.  So I'm exploring options 1 and 2 and so appear to be leaning towards option 1 as through 5 years of ownership the engine has been solid - no issues.

I didn't think much of that option as I figured it would be really expensive to buy a new truck outright with no deposit or trade in.  At least if the new breaks down, then you would still have the good-ole T1XX available for use.

Not a fan of the 2.7L's as the idea of a very small engine in a full-size truck is very unusual to me.  However, they do make decent power for an engine of that size.  I'd probably go for the 3.0L.

Unless you need to tow heavier weights don’t. 2.7 has had no mechanical issues. None of the other lines can say that.

The recall on them is not related to the DOD system, its a bearing, rod, & crank issue.  Because of this, I am not sure that you would want to tear into the motor with low mileage on it, just to replace the DOD system. HOWEVER, i did tear into mine and replaced all the lifters at 120K miles, so I cant really argue against it if you are high mileage.  The costs for parts was around $2-$2.5K and I replaced lifters, rods, fuel lines, and gaskets throughout. Timewise, it can be done in the driveway over a weekend.

I plan on keeping mine. If for some reason, it decides to go south then I’ll fix what needs to be fixed. It still would be cheaper than purchasing a new truck.

Would the L8P fit as a replacement for a boogered L87?

Just an idea. Keep the truck and disable DFM with Range Technologies module. Its a roll of the dice but its only about $300.00. I have used them on 3 T1s including my 2025 w/6.2L.

I’ve had a Pulsar LT installed for a few years now, unfortunately the lifters can still physically fail but it is less likely.
