Thank you for the response and especially for this helpful tip. I had no idea that a locksmith could do this!! I assumed that these new keyless FOBs were some kind of proprietary digital thing that GM would have to supply.

Thanks again!

I'm new to the forum and would appreciate any and all ideas or suggestions.

Just took delivery of a 2023 Suburban Premier 5.3L (4WD) with 12,000 miles on it. Bought it from Carvana (my first internet vehicle purchase) and overall the experience has been positive. I have 7 days to return the vehicle if I'm not happy with it.

The price seemed to be competitive ($54,500) in my view, especially for a 4WD with low mileage and clean Carfax. Plus they made me a fair offer on my trade-in. The 2023 does have one minor, quarter sized blemish on the front driver side fender where someone did an amateurish job touching up a scratch.

Here are my initial thoughts and observations, as well as a few questions:


1. What are the most common problems with the 2022(+) drivetrain on the 5.3L / 4WD? I traded in a 2015 Suburban LT and loved it. I got 130,000 miles out of it without a single mechanical failure. Hoping and praying I'll have the same experience with this 2023.

2. What are the most desirable or "must have" upgrades or modifications on these current 5.3L Tahoes and Suburbans? I am 99.9% sure that I want to install an AutoStop Eliminator - but does anyone know if this causes warranty issues with GM? Any other suggestions or recommended modifications?

3. A few other miscellaneous observations:

The shifting feels a little weird to me. This could be due to the fact that my 2015 had a 6 speed transmission whereas the 2023 has a 10 speed, so perhaps I'm just feeling more shifts?

I'm disappointed that they took away the adjustable pedal feature. I loved that feature on my 2015 Suburban LT and I was surprised to discover that it isn't on the Premier trim package.

4. My only gripe (so far) about Carvana is that they did not disclose that it only came with one key. I haven't priced a spare key yet, but still ... bummer. Any thoughts about whether I should make a stink over the issue? Would it be worth it? To be fair, the listing didn't say anything about the number of keys, and I didn't ask. But they asked multiple times if my trade-in came with 2 or more keys, so clearly it's a big deal to them when they are buying!

Thanks for any feedback! I'm enjoying the forum so far and have already learned a lot.

On my new Tahoe, the "must have upgrades" 1) Install device that permanently overrides engine stop-start. There's a good chance the vehicle already has it. I use the one that installs behind the dash, it retains full functionality, but it remembers your selection and KEEPS it that way. 2) Disable Daytime Running Lights. the Chevrolet dealer can easily do this through programming. Most government vehicles or law-enforcement vehicles have them turned off for economic reasons. Some dealers won't do this. This may be more difficult for you because you don't have a relationship with any dealer.
