I've been dealing with them for the last couple of years and I always seem to have an issue. One time I went because I had coolant leak and wanted to know how much it would cost to fix. I was told they wouldn't know without doing a diagnostic test which was a over $100. They took about an hour and a half to do the test and told me what all was wrong with my vehicle. The total would have been around $200 bucks to get it fixed but everything was under warranty so I just had to pay for the diagnostic. I agreed for them to service the issues noted. Another two hour wait and the rep comes back with a deep sigh and sad face saying unfortunately there was a totally different problem with my car--this time, something was broken and that it needed to be fixed or else I wouldn't be able to drive the vehicle. This broken part was upward of $400. This was a red flag to me because 1. You just did a diagnostic-- the entire point of doing one is to find any potential issues with the car, yet the test didn't tell you about this MAJOR problem??? 2. You tell me that this issue wouldn't be covered under my warranty. Why not? My warranty covered any internal issues that kept the car from functioning. The warranty should cover it. 3. I DROVE THE CAR THERE, without any major issues. I Immediately see this as a ploy to get me to pay the dealership SOMETHING out of pocket since my warranty covered everything else. It appeared to me that if the broken part on my vehicle wasn't discovered during the diagnostic test, then it was broken AFTER the test. I'm sure one of the mechanics broke it and they were trying to pass the cost off to me. I told him, I only agreed to the service that he told me about after the test and if something is broken then it's going to have to stay broken because that was never mentioned to me. He goes back and forth out of the lounge, I guess pretending to talk to someone, offering me a slightly lower price. Considering I wasn't budging with paying extras he finally said they'll just eat the cost on it because the vehicle won't run without it. Now I've been to several mechanics and NEVER had any of them decide to absorb $400 on ANYTHING that was supposedly the "fault of the customer". They tried to rip me off yet I wasn't falling for it so they gave up. I've also had a separate issue with their sales department . I was cold called by a rep who wanted me to do a trade in. After giving me the details she said she had to check my credit to see what my payments would be if I was to refinance. I told her I was not interested if I needed to do a credit check as I was in the process of repairing it. As a last ditch effort to get business she promised that she would do the calculations herself to get a range of what I'd might pay, that way she wouldn't have to check my credit. She said to make sure she got my info correctly she would send me a link to fill out my details and it would come directly to her and I agreed to do so. She called me back giving me some numbers and I decided I wasn't interested. About 30 minutes later I started getting notifications via email that I had hits on my credit, as this person had essentially shopped my information to banks trying to get the payment information together. I was pissed. Naturally I emailed supervisors and I got the brush off essentially saying when I filled out the link that gave them permission to run my credit. Total scammers. The only reason I didn't rate this a one star is because they do send coupons for oil changes which are relatively cheaper than going anywhere else. With my last oil change the rep just seemed like he was annoyed by my presence and was a little condescending when I inquired about the shuttle. Then he went off to get my paperwork and it was like a light switch went off. His whole demeanor changed. He was suddenly pleasant and very accommodating. This continued when I came back to get my car. At check out I saw a sticker on my paperwork that I was selected to fill out a survey on my visit. That's probably what brought on the sudden "customer service".
