AutoZone

My check engine light was on and I had already had it diagnosed by Honda. One of my O2 sensors was out but I needed to know which one (upstream or downstream). Luckily I had called Honda Service department and was knowledgeable about the issue.
I went to this AutoZone to have them read the engine code and tell me which sensor was broken so I could purchase the part from them. The guy came and read the code from my car and we then went inside to print out the code error.
The two error codes were both for the same exact part on the car that was broken. Bank 1 Sensor 1 (downstream O2 sensor). One code meant that the sensor was slow to respond and the other code said that the heating element was out on the 02 sensor.
The AutoZone employee tried to tell me that the two codes meant that both of my 02 sensors were bad and needed to be replaced and that he would be happy to order them for me. I argued with him and said that actually only the downstream sensor was out and that the printouts of the error codes he gave me clearly said in writing that they were both for the same sensor.
He said «Oh yeah, but you’re supposed to replace both sensors at the same time.» As if I’m so stupid that I think these are tires.
This just reinforces that fact that there is more dishonesty in car repair than maybe any other profession other than dentistry…
DON’T USE THIS LOCATION OF AUTOZONE

Anytime I needed something from here I found it. In my latest attempt at car self-​service it was to pick up an adhesive/​sealant to reattach the gasket that sits between the windshield and roof of the car. One $ 5 tube of Goop (and new wiper-​blades while I was there) took damn near 15 minutes to check out because everyone was working the returns/​exchanges line.
When the cashier was finally freed up to check people out she couldn’t. Why? No password to the register.
I really hate giving low reviews, I do. This store is convenient and like I said, I’ve never had an issue… in fact lemme tell you a good story from long ago:
I didn’t even know how to change the wiper blades or even what to look for when purchasing wiper blades when I first got my car in 2003 (yes this isn’t a current story but it does illustrate the point of what this store is capable of) One of the staff was very helpful in not only pointing out «the book» but showed me how to remove and replace one of the blades without cracking the clip before I checked out.
I do understand that it’s important to handle exchanges and refunds as quickly as checking out regular customers but one aspect shouldn’t have to suffer for the other.
At least when the cashier is back at the register they should have the tools to get their job done.
