After a 5 hour road trip (S. Tahoe to home in South Bay Area) in our MX yesterday, we got a low tire pressure warning during the last 15 mins before reaching our home. Thank gawd it happened then and not during our trip in Tahoe or worse, during the drive to or from. We tried out the new Tesla Mobile Service (mobile tire repair van) and here's our experience of the new pilot program. After calling their Roadside Service department, they said they could come out immediately, but I scheduled it for later in the day since I was at work (MX was at home). Their tech Mike (friendly, informative, and overall awesome guy) came to our home with a service van fully stocked with tires and wheels. He had my exact replacement ContiSilent 20" rear tire just in case the tire wasn't repairable. I had previously found the source of the leak coming from a screw that was in between two of the tire's treads (in one of the "valleys" between two treads that make contact with the road--see pictures). Mike was confident that he could repair the tire ($57 and change), saving me the expense of replacing it for $350. Phew! Our MX has only 2500 miles on it. Contrary to what I've read here on TMC, the MX CAN be easily jacked up with a floor jack. Some others have posted that it's not possible due to the frame not being strong enough for a corner-jack due to the vehicle's heavy weight, etc. I'm confirming that the car can be jacked up by a floor jack when done properly. The wheel was removed from the car and taken to the van. He had the tire dismounted very fast and showed me the culprit of the leak, a fricken 2" drywall-type screw (see pictures). Equipped with everything he needed to fix the leak and re-balance the wheel, he was done in 45 minutes flat! (sorry for the pun, but I had to). Here are some pictures that not only show the screw that caused this, but of the Tesla Mobile Service van too. Mike even offered me a cold drink while waiting, as well as a coloring book for my daughter (they've thought of everything to make sure the customer is comfortable while waiting--pure genius!) The small cost of this flat repair was well worth it. It saved me time and the hassles of taking the car into a service center, waiting, taking time off of work, etc. I know some tire shops will repair flats for free, but I wanted Tesla service for this issue, and to see how this Tesla Mobile Service works. The Tesla Mobile Service worked really well for us. Mike said that they currently have 2 vans in operation here in the Bay Area, and 3 more coming soon in preparation for the Model 3 coming out in volume. They currently cover from San Francisco to Gilroy. It makes a lot more sense economically, than building service centers all over the country. I will definitely use it again the next time we need eligible service.
