Well it's been awhile since I posted last and I wanted to update what is going on with my vibration issues. As previously stated I've had the truck in the shop 3 times for a total of 26 days trying to get the vibration issue fixed. The vibration was occuring when my 2014 Silverado 1500 4X4 went from V6 to V4 mode. Once in V4 mode the steering wheel and truck would vibrate. The service manager after replacing the ring/penion and force balancing tires, and finally changing tires from Goodyear to Contenial, that he had no idea why this was occuring.
So I approched the general manger of the dealership to request a buy-back. He told me to open a case with GM and he'd work on finding out what to do, which I did. Now in my mind we're talking buy-back but in the general managers mind he was offering a trade-in. Huge difference. When they made me the offer I was getting $7K less for my truck and having to pay $2800 more for the new truck. Not a good deal for me. I told them I wanted a even trade on the vehicle with NO money out of my pocket. He said he'd have to contact GM to see if he could get anymore incentives. Well after 5 days later after I had to call back to get an update and of course he told me that GM could not do anything else and asked me if I'd like to proceed with the trade-in. I advised him I'd call him back.
Needless to say I was not happy with the deal and that evening I filled with the BBB Autoline to proceed with Lemon Law. It was amazing the very next day I got a call from GM Senior Advisor asking what the issue was with my truck, what I wanted, and which dealership I was working with and the contact name there. I went over everything with them and they advised they'd get back to me in a few days.
True to their word they called me back with an offer. That offer was a buy-back of my vehicle, MSRP of my truck for another vehicle of the same or less MSRP. So yesterday I found another truck, 2015 Sliverado LT V8 which I submitting through the GM senior rep this morning for replacement.
All in all I guess the squeeky wheel gets the grease and if you do have issues don't be afraid to report your problem to the BBB autoline. They are there to help and arbutrate if needed, but all I had to do was file with them to get GM to call and start the process. Thanks to this board for all the post and advise. It really helped.
