I have a 2011 SRX Luxury Cadillac that I purchased in February of 2012 with 7500 miles on it. It now has 67,042 miles on it and it has been a great car! Recently it has been losing power initially when I want to pass, sometimes when turning a corner, or occasionally from a stop light. Several times I came close to being rear-ended because of it. I will be going in for an oil change soon, but I am hoping to have an idea of what might be the cause... as a single person I don't want to be taken advantage of. Any help you can provide would be much appreciated.
