NHTSA Complaint #11440973 — 2017 CHEVROLET SILVERADO 2500

On 09/30/2020, I purchase a used 2017 Chevrolet 2500HD work truck. Since the day I started driving, I been replacing tires every 2-3 months. I was told by different people, it’s normal because of weight. I took the truck to, suspension specialist, he said it was axle and wanted to charge 4000, didn’t have that money and decided to change tires, instead. I called dealer and explain, he said that maybe I cause it. This people are no help. Today, 11/18/2021- 5:18 pm, the center of the truck, between cab and rear bed, is sunken, it looks like the body frame got bent. It’s bad. I call dealer and spoke to Mr. Arbi, he said there’s nothing he can do and it’s my problem. I’m not going to start arguing and just told him thank you and decide to report him. When I bought it, I was told it was on a minor accident, nothing major. I don’t think so. I’m no expert, and I can see the body frame, bent. This dealer got me upset, just thinking that I’m stuck with this problem, and now I need to figure out how to fix, is the body frame. Please, help me, advise, what can I do, since I finance this truck. I, can’t drive it, I need to tow. I wish I can send picture. Thank you, any information will be appreciated. Miles when I bought, approx. 75000+. Miles today 11/18/2021. 143764
