While you have it at the dealer the valve covers should be checked for oil leaks. It is hard to see in there with the stock engine cover in place. To remove it well it just pops straight up and out of the way. check for leaks just below the oil filler tube. and around the spark plug wires.I did that repair with the ic pump as one visit on the $150 deductible ( certified used warranty) Be ready for the dealer to be clueless about common problems with these cars.
