2015 Yukon Denali 8 speed transmission 6.2L Engine, still under powertrain warranty
Had issues with vehicle sometimes jolting forward as we were coming to a stop, also occasional hard shifting.
Took it to local GMC dealership. They said it's a known issue with programming and they would need to reprogram the entire computer system. They said it's not a recall and not covered under our existing powertrain warranty because it's "not a part failure of the transmission". Then said it would cost us $525 for them to reprogram.
Is this BS?
Should I call GM directly?
Do they have to reprogram all systems or just the TCM?
Would this be covered on the federal emission warranty (we are under 80k miles)?
Side question, if they reprogram everything, might that enable apple carplay?
