Sad to say, but it's been a disappointment there at Bert Ogden GMC with the my truck that I purchased brand new (GMC Sierra SLT crew cab 2015), so the truck was not cheap. I've been very patient and taken it over 12 times over these past two years to get it fixed and nothing was resolved. If you looking to purchase, take in consideration that your brakes are going to squeak after the 5 month and their response is that it's absolutely normal. If the employee would of at least brought it up during the test driving it, i would of taken it into consideration before purchasing. Also their so called fixes only last for a month or two and then the problem reappears.
FYI it was around 6,000 miles when the problems appeared and as of now my truck just hit 20,000 in the span of two years. I been making monthly payments just so I can have my truck visit their shop and try to get fixed.
Oh yeah, instead of fixing my truck, their other response was " Purchase a new truck". My truck had only been 1 year old when I was told this.
*bert Ogden, I'm still waiting for the specialist that was going to check my brakes and it's been 2 years*
