I recently took my 2009 Chevy Tahoe to the 6th Street Charlotte, NC location of McCarthy Tire. I've been a long time customer of this location. Before it was a McCarthy Tire Center I had my cars serviced with Gerard.
I asked for an oil change and for the mechanic to check out the check engine light. After running the codes the mechanic determined that the issue was my gas cap was loose. I was charged $85 on my bill for this determination in addition to $30 for the oil change.
I realize this is a business and you've got to have a margin, but I feel that I was taken advantage of on the $85 charge. Many of your competitors offer this diagnostic service for free. And there was no real auto repair service required or rendered.
While I like the location of McCarthy in Charlotte and the ability to drop my car off at the location and walk to work, I will not be having my car serviced with McCarthy Tire again. Their competitors are offering a better value.
