've been bringing my vehicle here for years. When I needed a vacuum leak fixed, I trusted them like…read morealways and approved the estimate. Picked it up with the check engine light still on. Codes showed the problem had been there for hours - they never fixed it. This should have been a straightforward repair. When I asked what happened, staff were dismissive. Aliyah claimed my CV axles were causing a rough idle and suggested replacing them. That has nothing to do with a vacuum leak. I asked if they'd performed a smoke test. She said no because of a tear in the intake hose. But you have to seal the intake to run a smoke test - the tear would need to be fixed first for any diagnostics to work. Either they didn't do the work or they're making excuses. I paid for a simple fix I didn't get. After years of loyal business, I expected better. This isn't the shop I thought I knew. Feels like they took advantage of that trust.

I just want to say that there was a guy that worked there when I first started to go there he was Asian I don't remember his name. I felt that he was trustworthy. These guys now I feel they are not. I feel that they are just trying to make money and don't own up to the mechanics mistakes. I really think their mechanic needs more training or a new mechanic. This will be the last time I wright about this and I will be going to a new place that seems more transparent .they said they will let me look at what is leaking .when I tried to do that they made me go out of the area. Thankyou whomever is reading this

That never happens here. They are always busy but gives everyone respect and personal attention. I even came in on a super busy day because my tires were low and they were able to take me free of cost to fill up my tires. Amazing service from the gentle man who was filling my car. He was great! I can't remember his name, but he is Mexican and we were bonding over Filipino experiences. Then when I was leaving another worker opened my door for me. Stand up place! The servicing was just over $100 and that felt very fair. I will continue to take my car here and highly recommend then. Overall, 5/5 stars.
