There was a problem with our engine for about a year. But every time we took it to A different dealer,they told us there was nothing wrong with the car. One time in to Beaverton GMC and the problem was discovered and fixed. Not sure who the mechanic was but he deserves a raise! Thank you so much. Bill came to my rescue as always when I had a flat on the loaner. And Nathan came to my rescue when I left something a returned loaner. Great service!
