Noah was rude. After purchasing a set of tires and having an appointment scheduled for installation I came to drop my vehicle off and was repeatedly asked if I had already purchased the tires or if I was told the tires were in stock. I was given an appointment immediately after purchasing and was continuously asked such an idiotic question even when presenting a receipt. They managed to leave the left rear tire of our vehicle at 14 psi. Amateurs. .

Merced Costco Terrible Manager ADAM
I have always appreciated Costco’s great value and customer service, but my recent experience at the Merced location was disappointing. I had an interaction with a manager named Adam, and unfortunately, his approach was less than professional. Instead of providing helpful assistance, he came across as dismissive and unapproachable.
While I understand that managing a busy store can be stressful, I believe that every customer deserves to be treated with respect and courtesy. A little patience and a positive attitude go a long way in ensuring a pleasant shopping experience. I truly hope that Costco maintains its high standards of customer service and that interactions like this are addressed constructively.
I will continue shopping at Costco because of its great products and pricing, but I hope to see improvements in how customer concerns are handled in the future.

Had an appointment for 130 to have TPMS replaced. Arrived at 115, they said we are extremely busy it will be an hour to an hour and a half. Walk around Costco, get a call at 1:50 saying they needed to replace two TPMS sensors. I said go ahead. Over an hour later I am still waiting. I watched the service tech drop my Denali wheels face to face without a care in the world. They had all the tires on and then had to remove the two tires they put new TPMS sensors in and changed them again. This place is a joke. They have no idea what they are doing and have no care for peoples property. As I am writing this I am 2 hours into this and still do not have my car out.

Touo was very unprofessional and pushy on Monday, Sep 23rd around 7 pm. I ended up not buying at the end. Later on he followed me and my wife outside while I was filling my tires with air, and took a picture of my cars and ourselves. What kind of a person is this?
Since when Costco employs people who may be dangerous to its customers?
I’ll take my business elsewhere this time, and hoping not to see him there when I need tires again.

Booked an appointment, came in NO RECORD OF APPOINTMENT, CLERK GOT NASTY WITH ME. NOW WE HAVE TO WAIT HOURS, LIKE WE HAVE NO APPOINTMENT. DO NOT USE MERCED COSTCO, MANAGER ADMITTED TO ME MERCED COSTCO IS AN UNDERPERFORMING STORE! I also was charged more than the quote for the set of tires because they had the year of the truck completely wrong. But I gave them the exact tire size off of the tire so there should be no reason for the quote to be wrong. So we ended up paying $200 more. Because they can't get the prices right or the year of the truck or the appointment right.

I came in with a flat tire close to closing time and Justin assured me he could get my tire fixed. There was no other option at that hour so he saved my weekend by going out of his way to get the repair done in time.

Outstanding service!!! Ten star rating. Showed up on a Saturday afternoon. The manager Adam assisted me. I brought my Mom’s car in because the tire light was on and Toyota could not figure it out. Adam (A+) took the extra time to find the hidden pinpoint leak, called me with an update and the whole team was just awesome. Momma (87) was thrilled. She was stressed about this. You guys are superstars!!!!! Best, Kari and Leanne

Was trying to get a quote on a tire after a blow out. Was on the phone with my dad and the dude told me I need to get off the phone or he won’t sell me a tire. Also ordered a set of tires for my truck a couple years ago paid for everything only for them to tell me they couldn’t put the tires on my truck. Why I have no idea. Service here is ridiculous given them 3 different chances in the past 2 years only to be let down worse and worse as time goes on.

Thought I needed to get my tires replaced due to other technicians at other places telling me so but Adam (I believe that was his name) let me know that my tires were fine and would be for a couple of months! Also, they also accidentally had ordered the wrong tires for my car, which was no problem because they didn’t need to get replaced at the end but he explained to me that everything was fine. Ended up getting a refund for the tires ordered, but he was super kind and explained everything thoroughly! Will be coming back in the future once my tires do need to be replaced and definitely would want him to do the service.

Both the door staff and the employees working the food court were rude, and made me feel like I was inconveniencing them.

I have always loved Costco merced for many years. Until today... we took my mentally challenged older brother to get him a new TV. We somehow got separated from my husband who was taking our groceries to the car. I didn't have my card for reentry. I was waiting for him at the exit doors explaining to Juan my dilemma . He just kept telling me I couldn't stand at the exit and to move out of peoples way. So I went to the entrance and pleaded with the guy to let me look for him. He was kind enough to do so! afterwards I was both relieved and angry, I let Juan know what he didn't was really sh*#+y!! He just laughed at me as I started to cry. Maybe Costco can consider hiring some empathetic workers!! They have MANY of them!! Someone like the dapper gentleman at the door versus Juan who thought the situation was laughable!!
