I'm looking to buy a low mileage Truck based SUV for traveling and to replace my Chevy Van. I like the look and size of the Chevy Tahoe but the recall notice and issues with the Camshaft and FDM for their V8's are a concern. So I have a bunch of questions.
1- On the 6.2L V8 once its passed inspection and running 0W40 oil will that cause the check engine light to go on and post a P0016 Error code prior to failing on the highway at 70 mph? I really don't want a vehicle that freezes up on the highway in traffic without sufficient warning.
2- When looking at a low mileage 5.3L or 6.2L V8 Tahoe how to tell if its using a quart of oil every 1,000 miles? I don't want a vehicle that burns oil.
3- I've read that the 5.3L and 6.2L engines use the same camshaft. Is that true? If so then will the 5.3L V8's running 0W20 eventually have the same issues? If I run 0W40 in the 5.3L just to be safe does it void the warranty?
4- The recalled 6.2L vehicles have a new 10yr 150,000 mi engine warranty. Verses the 5.3L only having the original 5 yr 50,000 mi warranty. I keep my vehicles a long time and this might be the last V8 I buy. Leaning toward the longer warranty with the known issue?
5- I've found DFM defeat devices. I haven't seen anything on exactly what they do. I assume they block the command to the engine control computer to deactivate cylinders and pass all other commands? What happens if the module fails? How reliable are they? Do they work well? Would you use one on an engine that is still under warranty?
6- Looks like my forever Tahoe with Premium or RST packages and less than 30 kmi is going to run 55-65 k$. Having a hard time thinking about purchasing a $60,000 used Tahoe with an engine with known issues. While i already have a 2016 Chevy Van with a good 4.8L V8, no FDM, and no Start Stop. Its just really noisy and not a good road trip vehicle. Is the Tahoe ride worth it?
I wish I was paying attention in 2021 when I might have picked up a 2020. But I hadn't outgrown the van yet. My needs have changed. I really need a 2023 Tahoe RST with a 6.2L V8. or not?
