I took my vehicle to this shop based on their positive Google reviews, hoping to find a reliable…read moreplace near my new job. I was told my brakes and tires needed replacing, and as I commute long distances I wanted to make sure my vehicle was well equipped to handle winter conditions on the LIE. After my inspection was finished, I was quoted $1,079 for the brake replacement, new tires and the inspection, but when I went to pick up my car, I was charged in two installments (as the repairs took place on separate days) and the total was nearly $1,400--almost $320 more than what I was told the total would come out to be. To make matters worse, they removed my front license plate covers and replaced them with their own advertising covers without asking for my permission. Not only was I upset by the unauthorized advertising on my vehicle, but they also put my front license plate on upside down. (See attached photo for proof.) The final straw was hearing my brakes grinding after they had supposedly replaced them. This was incredibly disappointing and left me feeling taken advantage of. I had hoped to find a trustworthy auto shop for future service needs close to work, but instead, I feel like this place took advantage of my situation as a young woman needing an inspection. I won't be returning, and I strongly recommend you get a second opinion before trusting this business with your vehicle.

I hop in a vehicle and head from Southampton to Hampton Bays at 9AM on a monday knowning the trade parade will be there for the return yet fine with it since they had the oil. I get there and some clown who says "I spoke to you" goes in the back to get the oil. After 2 minutes the clown returns with 15W-50 and says this is all we have. Next the trade parade and a wasted hour. What morons.

They didn't have it but looked it up and ordered it for me. This was on a Wednesday night. By Thursday morning the fluid was there and I picked it up. That was great but it's not the best part of the story. I'm a woman and I'm not always comfortable trying to shop in an auto parts store. The staff at Advanced Auto are always friendly and extremely helpful. They are never impatient ,even when I'm not sure just exactly what I need. I wouldn't think of going any place else. They definitely deserve the 5 stars. Carol G.

New *** UPDATE ***…read more11/12/25 My interaction with the team over at Riverhead Mazda service department was so impressive that I came back the following week to purchase a second car!!! Again I was treated with respect and a knowledgeable team effort to ensure my needs were met. Special Thanks to my sales advisor Robyn who made herself available to me even during her time off to answer questions and assisted with connecting me to onsite staff promptly. Gerson (sales manager) worked together seamlessly with Robyn from start of sale until the end. Again Riverhead Mazda Team went way above and beyond! ***Original Review *** 11/02/25 Phenomenal SERVICE DEPARTMENT!!!! Thank you Greg Williams and your ENTIRE Service Team for providing me with respect. After purchasing a Mazda from another dealer in Huntington not only were you able to finally fix an on going issue that I had been having since day of purchase (from them the previous year) but you and your team went above and beyond to rectify my relationship with Mazda after their dealership dismissed and minimized my issue (while failing to present the product that I paid for with my hard earned money). You were HONEST, informative and attentive the moment I walked in which made my experience easy and amazing. Good people are hard to find, thank you for being one. I am so happy and will not hesitate to be a return customer with you and your team at Riverhead Mazda. THANK YOU!!!!
