Beyond disappointed with this dealership. We bought a new Chrysler Pacifica a year ago, after shopping around, these guys were the friendliest and from our hometown of Houston, so we bought from them and have brought our van in for all the scheduled and recommended services this year.
The problems started from the beginning, our van had a putrid smell, an issue that went on for over 7 subsequent visits. Each time we would get our van back smelling so strong of deodorizer you could barely breathe. The 2nd or 3rd visit they actually checked the passenger compartment air filter, it stunk so bad that the service advisor, Sherry, wouldn't even touch it and almost gagged when she showed me the filter. Eventually, after contacting Chrysler and attempting to seek arbitration, I was contacted by the dealer and the problem was actually fixed, after 7-8 months. We have actually never had that "new car" smell.
We have had what I feel is an unreasonable amount of visits for warranty work, each issue has required multiple visits.
This last week was the worst. I bring the van in because the Auxiliary battery, that was recently replaced, was not working again and the rear hatch, that we had been in twice recently over because it wasn't opening and closing correctly, still wasnt opening and closing correctly. The passenger front tire was losing some air so I asked them to check the tires as well because we were going out of town this weekend.
The service advisor, Marc, called and informed me the van was ready but I had 2 bald tires in front that would need replacing. I questioned why a new van with only 15k miles needed new tires and he informed me that my tires have never been rotated, even though I have brought my van in for all recommended services. He said I had to specially request tire rotations, which I had, specifically asked the other advisor I had previously been assigned, Robert, and he told me the tires were rotated when the oil was changed, not to worry about it. Marc then tells me the only thing I can do is take my van to Discount Tires and see if they will warranty the tires because they are a Nexan dealer. I called Discount Tires and they informed me that l need service records showing proper maintenance for any warranty. After getting the van back, the tire is still losing air, only now the tire had been moved to the driver's side, I go to get air and the guy spots a nail in the tire and a big red scuff on the wheel.
I contact the service manager yesterday, explain everything and inform him that I have family coming into town and we are supposed to be heading to Northern AZ for the weekend. Today around noon, when we are supposed to be leaving, he contacted me, told me to come in and he'd take care of it and get me on the road right away I drive out and wait, after 30 minutes the tech informed me that all 4 tires have nails and staples in them and need replacing but they don't have the tires in stock.
So here I am, at Discount Tires, while my family, that flew in from Houston, angrily got a rental and went without me so they didn't lose all the money they spent on the tours in Jerome and Cottonwood they had planned for today.
I still haven't gotten a single answer about why the services on my vehicle weren't done aside from "I don't know" and Dave telling me that he hasn't had time to check into it.
