Otto Cadillac - Service Center

I was warned not to use this dealership due to poor service, dishonest salespersons, and ridiculous mark up on sales and service but I didn't listen and now I am paying the price. I bought a Certified service, dishonest salespersons, and ridiculous mark up on sales and service but I didn't listen and now I am paying the price. I bought a Certified pre-owned 2008 CTS from OTTO with many issues such as rear end failure at 60k miles, rusted out break lines, bad steering shaft and ECM issues. Major parts that shouldn't fail on a new car. I also bought the extended warranty ($2,200) for add protection but later I found out that this warranty doesn't cover any expensive parts just junk that doesn't matter. Here is an example of how the service department lies and deceives customers. Customer- "hey my car burns a quart of oil every 3k miles" Service- "sir that is incorrect, your car consumes a quart of oil every 3k miles which is normal for a Cadillac". Word play or con artist? The bottom line is a new car with less than 60K miles shouldn't eat a quart of oil unless you have leaks or engine problems... common sense. I feel sorry for the elderly, women or people not mechanically inclined that don't know any better cuz these fools will rob you blindly! More
