2024 GMC Denali Ultimate
Justin Mullinax, 09/03/2023
2024 GMC Sierra 2500HD Denali Ultimate 4dr Crew Cab 4WD LB (6.6L 8cyl Turbodiesel 10A)
I purchased and still have a 2024 GMC Denali Ultimate that I have had nothing but issues with since the second week of purchasing new. The truck left me and my family stranded in Walsenburg Colorado with only 1,253 miles on it. We called On Star to have a wrecker take it to the dealer. On Star wouldn’t send a wrecker because we had a 22’ utility trailer so we where out a wrecker bill. I … called Ferguson GMC where I purchased the vehicle from and left multiple messages for my salesman and the GM to see what my options were. I never received a call or text from either. One week after the day it broke down I did get a call back from the service manager MIKE GENOVESE . Mike informed me there was nothing they could do since it was already at another dealership. The truck was taken to Wilcoxson GMC in Pueblo Colorado where it sat for 6 weeks getting a new DPF filter and Pressure Differential Sensor. GM has still been unwilling to compensate for the 6 weeks of being with our primary vehicle used for work. We literally had to purchase another New GMC from Wilcoxson to get home as there where no loaner vehicles available. When our 2024 GMC showed up at our house through GM reunite program it had 680 miles more than when it was delivered to the dealership and there was no diesel or def fluid in the truck. We finally got a reimbursement check for the hotel room we had to get for 2 nights waiting for the dealership to open. I wouldn’t recommend buying anything from General Motors as they don’t stand behind anything. I have spent over 40 hours trying to get a fair compensation or Buy Back from GM and have yet to get anywhere with them. I was told they would Repurchase it and was told to get in contact with MIKE GENOVESE the service manager at Ferguson GMC in Norman Oklahoma. I called Mike to schedule a time to bring it in for the Buy Back and he didn’t know anything about it. So I called Shaun Gusumano back and he assured me Mike was brought up to speed and would be handling it. Once again I called Mike and still isn’t aware. If you are having any issues with getting ahold of GM please let Shaun know as he is not taking care of my issues. [contact info removed]
