I went to get in my car today to go to lunch and found an alert on the screen telling me that the right rear tire had 0psi pressure. I get out to take a look and sure enough...it's flat as can be. I know that there's no spare, but for how flat the tire is, no amount of "Fix-a-Flat" is going to make it usable again. There must be a nasty gash in the tire somewhere. My options are to have the car towed on a flatbed or jack up the car to get the wheel off. There's no jack...so...that's out. I tried to schedule a Tire Change via the MyChevrolet app but it just offered to help me call the local Chevy dealer to get the tire changed. I finally called them and they offered to send someone to jack it up, take the wheel off, replace/repair the tire and bring it back and put it on the car. Ugg....what a pain.
