Contact Titan customer service. Since their garbage products have this problem all the time, many many people have gotten partial refunds in exchange for just modifying it yourself to fix it rather than sending it back for a replacement. If you have the skill and equipment to fix it, that is great, but you deserve at least a partial refund because of their garbage quality control. And they will give you that refund.
Btw, what does it tell you about how much it cost them to manufacture this junk? they have so many manufacturing defects that they are willy-nilly taking return shipments and sending replacements or refunding money constantly everyday. And yet still remain a profitable company in business. It speaks volumes about their company. They have literally made a lack of quality control a business model.
