Business ProfileforGrubbs Nissan

On 11/18/23 I purchased a used 2018 Nissan titan xd. I put $1000 down on a $29,800 used vehicle. The buying experience was very expedient, so expedient that i did not notice essential components for safe operation were missing. Including a lugnut, spare tire kit, and ***** I also was not informed that the previous owner changed the tire size, this is problematic because the stock 17 steel wheels use a different lugnut than the 20 alloys that i bought it with. I only became aware of this after this most recent issue stated below. The spare is also still the stock 17. This has caused issues with me trying to use my vsc wrap warranty to rectify the issue. They are claiming the vehicle has been tampered with and refuse to honor the warranty. I also have had service issues. They had charged me for a tire rotate that was not performed, i know it wasnt because i had a slow leak in the front left tire which was still in that position. It took two more visits to finally get the rotate completed. On Friday February 9th my front driver side tire sheared off the lug studs and nuts after violent shaking. Luckily i pulled over into a parking lot and it broke off as i parked. Now they have gotten the new rim, ************* on but other lug nuts are backing out. No investigation, basically your vehicle is unsafe, come get it. Resolving this issue to me looks like getting a proper size spare, making sure all remaining 18 lug studs and lug nuts are the correct type for the 20 tires that were already equipped on the truck at time of purchase. This is beyond unacceptable. Please help.
