My Model S was showing less air in one tire. So I went to Costco and they filled it up. The guy told me that I have a nail in one of the tires. Costco said they will plug and patch it for $11. My question is: 1. Is it OK to get it fixed in Costco i.e. would they have experience with Teslas? 2. The guy at Costco told me that I have to release the suspension (or something like that) since they dont do that. Anyone know what he is talking about and how I can do it?
