Burien Chevrolet - Service Center

I'd been using Burien Chevrolet for some time when this happened. I'd been through a lot with them. Engine needed replacing because it threw a rod. $4,800 that cost me. Water pump went out. $290 that cost happened. I'd been through a lot with them. Engine needed replacing because it threw a rod. $4,800 that cost me. Water pump went out. $290 that cost me. Every issue I had, I brought my car too them. I get an SES light and I bring it to them, they tell me an oxygen sensor is out and must be replaced. I order the part from them for install. They install it. I see on the wall a poster promoting AC Delco parts and the quality of these American made parts. I trust they are quality no doubt. What really was a seller was that the Poster ALSO stated the following parts came with "Lifetime Warranties", including parts like Water Pumps, AND Oxygen sensors. I notice on my bill that there is no star next to the water pump ( a star like so * means it is a Lifetime warranted part ). So I ask the cashier/service specialist lady about this, and she gives me the blankest, dumbest stare like I asked her the square root of something. I hate to be harsh, but people with no obvious knowledge of automobiles should not be a "service specialist", but anyways she sends me to the gentlemen at the counter, Dwayne, and I ask why no star is present indicating a lifetime warranty. He laughs out loud, and says quote "Oxygen sensors are disposable parts, they go out no matter what and we don't warrant them forever." I pressed a little harder and his superior backs him up and says to some effect "GM recently changed their standards of what is warranted to life, Oxygen sensors no longer are in that category." I asked him why the poster was on the wall, literally 3 feet from him, saying otherwise. He just shrugged his chubby shoulders. I was young, naive, and 19 at the time so I didn't pry it. I think back now and I feel abused, like perhaps my youth was taken advantage of. I now do my own mechanics, but I never once returned to Burien Chevrolet. And that was 3 years ago. I plan on keeping that streak. More
