 I purchased my 2017 Kia Sportage with 34 miles on it on September 6th.  9 days later it has 347 miles on it, and I am having some problems.   The past three mornings the car turns over a few times before starting.  This morning after it started, it acted like it wanted to cut off.  The car does a lot of transmission shifting when driving in slower traffic, and sometimes it doesn't accelerate unless you press the gas pedal pretty hard.  When stopped at red lights, it's starting to have noise and vibration.
