100% agree! They need to fix the problem.

This is what GM customer care said to me, Thank you for your e-mail. We appreciate the time you have taken to correspond with us and offer your concerns and comments. Your comments have been documented. In response to your concern with the noise on yo0ur vehicle that they told you that was normal. Reason is each pulse makes a tone, which combined with the other pulses forms a harmonic series. The same thing happens in all engines, but it's the irregular firing sequence that gives a big V8 its distinctive throbbing sound. With regards to the heated/ventilated chips, there is no ETA yet available. Our teams have been working hard to find a solution to retrofit vehicles with these convenience features that our customers want to continue to enjoy. We are excited to confirm all vehicles covered by the previous announcement will be eligible for a retrofit process that will activate the operation of the heated and ventilated seat modules. This retrofit process will begin when parts become available and at no cost to you. Once parts are available to begin the retrofit process, dealers and customers will be notified accordingly. The retrofit process began in late Q2 2022, and we understand that due to the scale of the number of vehicles impacted, this process may take some time to complete for all of the vehicles that require retrofit. Your dealership will contact you as soon as the parts are received, and will make arrangements to get your vehicle in for service. Should you require future assistance, please contact us again through our website at www.gm.ca or call our Customer Care Centre, toll-free, 1-800-263-3777 or 1-800-263-7854 (French), Monday to Friday, 8:00am to 11:00pm, Saturdays, 8:00am to 5:00pm, Eastern Standard Time. Thank you for contacting General Motors of Canada Company. Please visit our web site again Regards, Valerie

I have a 2022 trail boss with 3500K on it and it dose the same thing, had it to the dealer 4 times now and have put multiple complaints in to GM and basically told me to get bent as this is a normal noise, and its like that to make the truck sound more like a V8...HAHAHA.. they even put a new exhaust on it and it still did the same thing. this has to be the most annoying noise ever, and wish GM would step up and fix the problem... if any one has any updates on how to fix that would be great.

Took the truck in to the dealer last week and GM said this is a normal noise and they will not replace the exhaust.. NOT HAPPY!! the service manager told my wife to put in a clime to GM and ask for are money back and give back the truck.... WOW!! they also started up 2 brand new V8 6.2L high countries they had on the lot and they also made the same noise, to bad they didn't have some trail bosses there to show me. they also aid they took my exhaust off and put an old one on that they had lying around the shop that had 120K on it and it still made the noise. GM also said the ratel/squealing sound is to make the truck sound more like a V8.... HAHAHAHAH, Bull Sh*t... any way I guess I'm stuck with this as GM will not do anything to fix it, you think that they sell over a million trucks per year and make billons they would do something for there costumers that spend any where from 50k to 80k on a truck.
