2014 GMC Sierra
SLT AT
crew cab
short box
Built in MEXICO 9/13
I have the vibration also between 65 - 75mph. The passenger seat shakes like hell, the steering wheel has bad wobble. My dealer had tire shop next door install BFG All Terrain 285/55/R20 before I picked up the truck so I don't believe it is the tires. I was waiting on the first oil change to have several problems looked at. Like most on the thread between my wife and I we have purchased 9 GMC trucks and Yukon's since 99. I guess I will have to deal with the BS (BEND OVER) and trade the SOB in on a TUNDRA.
So far....
headlight moisture
On Star has never worked
sliding rear window noise
bad vibration at HW speed
And once you've purchased, GM, or dealer for that matter, doesn't care.
REGRET is all I have
Don't bother with "We are so sorry to hear, PM your VIN" LOL LOL
