My car had the light on because something was definitely wrong with my tires. All my set of tires were bought at Costco with a full set of sensors. I usually go to Costco in Niles but there was no appointment slot so chose to visit the one in Glenview where I was able to get one of the last appointment slots. I waited definitely longer than I had expected, despite of having made the appointment because it was the day before a snow storm, and I was three days away from a personal occasion that would require some long distance drive. Despite this, I give these guys five stars because Costco Tire Centers never fail me and does their job to the level I want it to be. Sean was really awesome and cordial with great customer services, and I hope that Costco keeps him permanently. Peter was also awesome with updates and apologies for being late, even though they were all working late into the night to take care of my car. Not only I had my tires all fixed under the given Costco warranty, I have also found another great trustworthy Costco Tire Center in my neighborhood. Thank you, Costco Tire Center in Glenview, and I will be back! read more
