Two problems related to engine and engine cooling have been reported for the 2007 Lexus IS250. The most recently reported issues are listed below.
Camshaft gear gone bad at only 85,000 and Lexus is aware of and does nothing to do a recall. This is a 3000,00 fix.
On 02/06/09 the car engine malfunction light turned on as well as the other one's on the dash. The car reduced the velocity while driving on the highway and did not accelerate any faster the 40 mph. I took the car to the Lexus dealership service department. They stated it was a misfire in some cylinder and also some problem with the gasoline. They fixed it. On may 4, 2009 I had the same problem with the car. The car malfunctioning lights turned on and the car loses velocity while driving on the highway. So far the car has been at the Lexus service department waiting to be repaired. Lexus stated it is the vehicle motor pipes that need be changed and they have not arrived at the dealership up until today may 26, 2009. They have told me the vehicle motor pipes are on back ordered until June 2009. What can I do??? the consumer was informed the engine escape valves were broken. Updated 05/27/09.
