I have purchased a conversion van that has been modified by an aftermarket upfitter but sold as new on a franchised GMC dealership lot. The van carries two placards with conflicting gvwr information. These vans are being modified in mass quantities. The rear springs have been changed to soften the ride but are inadequate to support the weight of a 3/4 ton van. The tires that are being installed on these vans for vanity reasons are not of the correct weight rating for a 3/4 ton van. We have had major issues with the tires failing and the rear springs bending. The conversion company, the GMC dealer, nor GM customer service wish to address these issues. Yet these vans continue to be sold in mass quantities on GMC and Chevrolet dealer lots as brand new vehicles. I am seeing many online complaints in forums and facebook groups from other owners with the same type of issues. I am genuinely concerned that someone is going to be injured eventually due to tire or spring failure. Also I have been having issues with the seat belts becoming completely unbolted from the seats. The fasteners used by the conversion company for the seat belts are also inadequate for today's standards. Please understand that my complaint is not in regard to the oem spec GM van. This complaint is related to a GM authorized upfitter that is taking brand new vans provided by GM, installing their parts, then selling them as new vehicles at GM dealerships. This conversion company (the Explorer van company) also installs their products on Ford, Mercedes, and possibly the Ram vans as well. We have had three tire failures already because of this issue. Belle tire would not sell us a replacement tire because the size installed on the van is not rated properly and there is no tire manufacturer in the us that produces a tire in the proper size with the correct weight ratings.
