[ALLANQ]

2013 silverado 2500hd ext cab 6 ft bed 6.0 gas

vibration from day 1 dealer changed 9 tires roadforced balance,

gm rep with newest vibration analyzer says within gm spec and is normal

and gm is done. last vist to dealer they made vibration worse and gouged

my rims with impact gun they dont like when you complain .

gm cust service say theres nothing wrong with my truck and there isnt

anything to fix hired a lawyer for lemon

 

trying another dealer current 2700 miles 6 weeks of hell

 

update 12000 miles 2 more dealer visits 2 new tires and one new rim vibration worse gm wont settle have to go to court

so in 11 months 11 tires one rim 17 days at dealer first visit was at 700 miles adding weight to bed or towing trailer does not help

gm doesn't care they have been paid

I have an 11 Sierra 2500HD with 60k+ miles. I have the same problem. Only mine does it from 60MPH and up. Went from Falken AT's to Firestone AT's helped a smidge. Also noticed roads and temperatures make a difference. Did the dealer route, same results as everyone here. I hope GM put locknuts on the passenger seat. I swear one day that thing will just rattle off. Maybe all those vibrations is why the wife likes riding in the truck so much LOL
