So I bought my wife a used 2020 Tahoe Limited with 23k miles. Excellent shape and she loves it but we're having some issues with the starter. Occasionally when pushing the start button on the dash the starter will spin and not engage the flywheel. After fighting with the dealer over the course of several visits (of course it wouldn't occur while in their possession) they finally replaced the starter under warranty two weeks ago. Now the issue is worse and the non-engagement is occurring about every other day. Very frustrating to say the least. Note, back in June we were having some issues with low voltage and dealer determined that the battery was leaking causing low voltage and causing all sorts of issues. Dealer replaced the battery, thoroughly cleaned the battery tray area where some of the fluid leaked out and this appeared to fix the low voltage issues. I need to take it back to the dealer but any recommendations as to the cause? Dealer has been less than helpful since we didn't purchase from them. I'm thinking possibly low voltage issue still at the starter, chipped flywheel, what else?

Thank you for any guidance you all can provide.

I believe there is a tsb for that. This one rings a bell.

TSB #20-NA-218​


If its not that one search for more or one with your year truck. There are several.

Thank you very much. I'll look into these and see if the stealer can see if our vehicle needs these updates.
