| At approximately 40,000 mi. my 2007 lexus is 250 developed a problem of stalling, shaking, misfiring and the vsc light, traction skid light and check engine lights all come on. the dealership initially tried to tell me that the gas cap was not on tight (not true) and then they tried to tell me that just turning the lights off would fix the problem (also not true). after i insisted that the problem was serious and dangerous, the technician drove the car home and had the same problem that i had been experiencing. finally, the dealership decided that carbon had built up on the valves and that was causing the engine to misfire and all the lights to come on. the dealership sent the valves to a shop and had them cleaned and ground down. the service manager told me that there was a design flaw and this is what lexus told them to do to fix it. now, here i am at 81,000 miles and the same thing happened again yesterday with the car shaking, stalling, misfiring and the vsc light, traction skid light and check engine lights coming on. it has been another 40,000 miles and the carbon has built up again. i have read on the internet that many other people have had the same problem. | |||

| On 3/5/11 at approximately 8:30 am, i was in a parking lot traveling at about 5 mph in drive with my right foot lightly applying the brake when the brakes seemed not to hold as they should and the engine suddenly increased to 4500 - 5500 rpm. i applied increased force to the brake pedal, placed the gear shift into park, and noted the rpms climbing above 5500. i then pressed the start/stop button and the engine stopped. this episode occurred on dry, smooth asphalt on a clear, cold (30 degree) day. the engine was at normal operating temperature, initially running at near idle (in the parking lot), with the gear shift in drive, cruise control off, radio, cd, a/c, defroster were all off. heat and fan were on with interior temp set at 74 degrees. this episode has not repeated as of the filing of this report (4 days post-event). note: i was wearing sneakers, not any type of oversized winter boots. the car mats had been previously replaced by the dealer as a result of an earlier recall; no additional mats were in place. all required maintenance, up to and including 36,000 miles, has been performed by the dealer. | |||

| 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. *jb | |||

| We have returned 2007 lexus is 250 4 times to dealer for stalling while on highway. dangerous scenario. each time the service center stated the car was fixed only to get back on highway and again it stalls. the last two times the car would not go over 5 mph within 24 hours of when car was returned to us. the last three trips to lexus have been within the last 2 weeks. i dont think lexus has a grasp of why their cars are stalling | |||

| Sudden acceleration with 2007 lexus is 250. *tr | |||

| Unintended sudden acceleration while braking for a stop sign in a residential area. this was the only time of the occurrence, was able to stop it by turning off the engine. upon restart, problem resolved itself. it was taken to the dealer with description of the problem, they noted idle was up from 750 rpm to 1100 rpm, decided to keep it overnight for further investigation. we where contacted the next day and told that the problem was resolved. they advised us the found a loose battery connection. no parts replaced but resolution and problem don't make sense. we did not experience any other electrical problems before the issue. we have the factory oem standard floor mats, secured by the hook and it was not touching the accelerator pedal. *tr | |||
