I went to a independent tire shop to get an alignment done recently (car started pulling slightly left). They said I needed new tires not an alignment. (Lexus dealer agreed.)
Took the car to Maui Costco where I purchased them. They said the tires were still useable. Five-year warranty expires in
2 months although the tires only have 36 thousand miles with a 60 thousand mile warranty.
Long story short, after contacting Costco Corp and having a meeting with the local assistant manager, they won't warrant the Michelins because of "uneven wear". The notes they add at the end of each bill has a list starting with something like "Always follow Manufacturer's recommendations". A few times the receipt also stated "check alignment" among other things. I assumed it was CYA boilerplate.
Never once did anyone say or write, "your tires are wearing unevenly" or anything similar.
As a result I will have to spend $600-$800 on new tires when an $85 dollar alignment would have saved these tires. According to Costco's manager, the document history shows this alignment problem was already going on when I purchased the tires 5 years ago.
WHY NOT MENTION IT TO ME THEN OR ANY TIME SINCE!
We all count on our mechanics and service personnel to let us know when they spot a problem with our cars. There is a disconnect here, between the mechanics and the front counter and they really let me down.
I am still a fan of Costco after more than 20 years as a customer there and at Price Club before it. To her credit, the manager handled the issue very professionally.
