Thank you! This is helpful information - I appreciate it.

Hi Team - my dealership is struggling to figure out this problem - I'm wondering if anyone else out there has experienced or heard about something similar. Truck was purchased brand-new in December of 2022 and has 18k miles on it today. It has an interlock system that was installed in February of 2023 (the device I have to blow in before I can start the engine to prove I'm not drunk). It's a SmartStart interlock system. Around September for 2023 I had the oil changed at a Mike Maroone GMC in Boulder. After this I started noticing a noise when accelerating and decelerating. It's not the typical high-pitched noice of the turbo spinning up. To me it sounds more like a police siren. This video shows the noise: It's like a "woooooooo WOOOOOOOOo" noise After a while, I got the error message "Reduced Acceleration - Drive With Care" and a solid orange engine light. NOTE: I only get the "Reduced Acceleration" message periodically, when driving over 55 mph uphill. It goes away after turning the engine off and stays off for weeks until I accelerate up a steep hill again. The orange engine light goes away when the truck is very cold. I brought my truck to Foundations Chevy/Cadillac/GMC and they looked at it. The tech said the Interlock installation caused a leak to the air intake and they replace these parts: This fixed NOTHING!!! Still check engine light, still "Reduced Acceleration" message, still "woooo WOOOOOOoooo" sound. Brought it back to them and they said "well, maybe it's the turbo - let's replace the turbo". Now I've been waiting for over a month for the turbo part to arrive - it hasn't arrived and the dealership tells me it's backordered with no ETA. What I'm wondering is: 1.) Anyone else have any experience with a similar issue and can tell me anything about it? 2.) Will another dealership maybe have more luck getting the turbo part that Foundations hasn't been able to get? 3.) I have been driving this thing without issues other than the sound, the light and the error message, but I'm afraid to take it on a long drive up into the mountains. Can I keep driving it? Am I potentially damaging it more by continuing to drive it? Can I get the manufacturer to take the damn truck back since it has an issue that I can't seem to get fixed? It is under warranty. The interlock system was installed and Foundations tried to blame that for the issue, but it doesn't seem to me like they were correct about that. Any advice is much appreciated! Thanks Bobby

Hey all - new here - trying to see if I can upgrade the steering wheel controls on my brand new 2022 Sierra 1500 Pro - crew cab 2.7L short box. Photo attached - I just want to add the phone and radio controls to the blank on the right side of the steering wheel. I would even replace the entire wheel if that were an option. Just can’t believe how little info there is for this model and year truck! Any help/guidance is much appreciated.
