Lexus IS owners have reported 1 problem related to engine head gasket failure (under the engine and engine cooling category). The most recently reported issues are listed below. Also please check out the statistics and reliability analysis of Lexus IS based on all problems reported for the IS.
In August 2012 my car's engine light and vsc light came on. I took the car to the dealer and they found multiple misfires. The dealer replaced the gasket and 3 pistons and ring sets under warranty. My car engine has continued to intermittently shudder when moving and when idling at stop lights. Today (1/3/17) I was driving on the highway at normal speed and once again my engine light and vsc light are lit up. I received the 9 year extended warranty for carbon buildup, but it only covers me through 3/8/17. If I have carbon buildup again after that, it will cost me $2,000-$3,000 to fix. The engine failure in these Is250s (2006-2013) Is rampant and the car model needs to recalled and replaced.
