What 2012 GMC Yukon Denali XL owners say
Body & structure
I have been a long time buyer of GM products, I still have a 99 tahoe, 07 GMC savanna and an 02 GMC sierra hd 2500, recently purchased a 2012 Yukon XL Denali used with 22,000 miles on it from old saybrook GMC in ct, clean as a whistle everything looked, went to wash it and spray underneath in the first week after I bought it and noticed underneath the frame wax all pealing and frame very rusted, along with many other things rusting . My 02 with 170,000 miles on it looks better then this. Also went on line and there are a lot of people complaining about the same thing. Im sure more would if they looked under there car. This has got to be a factory defect and they need to fix this problem. The dealer is telling me thats normal , I disagree seeing I have multiple cars/ gmcs my wife has a 2012 passat we bought new and is spotless underneath, and we have done nothing to the car.
My vehicle was parked in my driveway, stationary, on a suburban street in a small town overnight beginning at about 8 pm on Friday August 12,2016. The following morning, August 13, 2016 at at about 7:30 am I entered the vehicle to go to the store and observed a large crack running perpendicular with the dash from near the window to a over the instrument cluster. This is a known defect with similar GM models between 2007-2013(14). The safety concern is that the poorly crafted plastic dashboard cracks easily with no pressure applied to it. This means that that in the event of a collision, with great pressure applied, the dash would disintegrate at an alarming rate and would lead to shards of plastic impailing the occupants of the vehicle with varying amounts of harm. This defect is well documented by several other GM SUV/truck owners for this year span of production.
Air bags
The dash board is cracked and rattles near the air bag. This is concerning that if an accident would occur, the cracked dash could cause further bodily harm. This defect just showed up unexpectedly and I am afraid will crack more as time goes on. I cannot recall if it occurred while driving or stationary.
Large crack in dashboard around airbag, and above control panel. Concerned about safety and efficacy of airbag, and dashboard in the event of a front end crash. Vehicle is garage parked. GMC wants $1,600 to replace on a 6 year old vehicle with less than 60,000 miles on it.
