Sierra 1500 8-cyl

  • 55,000 miles


#sb-10-06-01-008 (problem) I am concerned with our safety due to the mechanical motor problem with the cylinders. GM warranty # [xxx] I have had oil consumption test done and they ordered parts and told me to bring it in. When bringing it in to "philips Buick GMC" fruitland park Florida, I was told that I would be able to get a comparable vehichle in exchange while mine is worked on. I get their and they try to give me a compact SUV. I am 6'2", 200lbs. And drive a 2007 4 door Sierra 1500 that I use for my commercial business every day for work. They were aware of this. I shut my business down to half of what it was in order to be able to afford loosing my truck for a couple days to waranty repairs. I was told I would get a full sized truck or SUV. I still have to haul product for my business just to keep it 50% running for those couple days. I also have 4, 200+lbs guys to haul around for work as well, and a special needs daughter who needs the aditional space of a full sized vehichle. I paid over $40,000 for my truck. Its not my fault that I have a warranty issue and it has to be worked on. So my business, family, and self shouldnt be the one who is inconvienanced for a GM warranty issue. GM needs to do what it takes to make this right. I spoke to GM and they told me to go rent one myself and pay myself. They said they would only give me $35 dollars a day for reimbursement. With this happening GM is making it impossible for me to work and get my truck fixed at the same time. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).
