Brand new acura tl 2008 model. the rear left tire went flat without cause. i called the manufacturer they told me to go to mavis and have them look at it. i am on a donut and they expect me to go drive around. rather then shipping a new tire to my dealer so he can put it on they told me to go have it looked at it. this means i have to risk my life driving to a dealer who is going to try to charge me more money. i have 1,300 miles on my brand new car. *tr
