I purchased a 2003 Nissan Pathfinder in June 2017, I took it to emissions and it failed due to a catalytic converter and other issues. I took it immediately back to the dealer to have it repaired as their legal obligation within the 30 days. It sat at their dealership 1-2 weeks after being told by numerous staff members that the work was being done and that it is difficult to have a catalytic converter replaced and that was why it was taking so long. I even had to have a car loaned to us because of said work being done. When I picked up the vehicle I was told By the sales rep Carson that I'd receive proof of the work that was done. Nope proof never sent. Now here I am 3 months later with the same issue on my vehicle. I called the dealership and spoke to manager Gabriel Bustos who states the work was NEVER done on this vehicle. Why would it have sat at their shop and been promised by numerous members of management and staff both-sales and finance that the work was being done to only find out it NEVER WAS!!! I am beyond frustrated and will post reviews for this dealer ship everywhere that I can. I will also investigate what I can due further. The lies the deception and the disappointment!!!
