Their service department has no clue what they are doing. Took in my Yukon because I had a nail in the tire and I have a warranty. Arrived on a Tuesday and was advised 2 guys called and sick and come back another day. Came back Thursday, 2 hours wait to tell me they need to order a new tire as it can't be patched and won't have for another day or two. Then I said please swap out my spare as it is a full-size tire, waited another 1.5 hours and then they said they do not carry the tools to take off the spare?? WHAT?? They advised me to take to Discount Tire and buy a new tire. Well, I did take the Discount and guess what?? less than 1 hour and they repaired the patch for FREE!! I think they try to get out of fixing cars with warranty;s this is the 2nd time. Filing a BBB complaint. They SUCK!!! Funny thing is they texted me after asking if I would fill out their survey- I texted back for what? My car you said you couldn't change the tire on?? D
