I discovered that the psi for my r/r tire was not registering on my dash board. I was getting a "service required" message. I called about 9 a.m. and got an appointment right away. I took my car in. They checked my actual tires and the tire sensors and discovered that my tires were fine. They then reset the sensors. My tires were all registering the appropriate psi, and I was on my way. Because proper tire inflation is so critical to safe driving, I appreciated getting right in and having the issue resolved. I was treated very respectfully. Overall, great experience.
