Hello fellow Lexus owners I'm new to this forum I purchased a 2014 Lexus IS250 F Sport I have 13000 miles roughly in the last month or so I have noticed after driving a a few miles and park the car and it has been sitting for an hour or so when I get in it to start it up at initial startup sounds like a diesel I have seen and read on the older models in this forum that it has been a TSB for the cam gear I contacted Lexus and they are aware of this issue but on the older models has anybody experienced this on a newer model 2014 or newer any info very appreciated thanks fellow Lexus owners... please help
