Engine light comes on and the car stalls or cuts off. The vsc light and traction light is on also. There's a burning smell that happens often. In addition my acceleration pedal causes me issues also which has put a whole in mat by getting stuck from time to time.

Upon starting the car the car shook and got a vsc and engine check light. Called the dealer right away and they said they would have to charge 100 to see what happened. Come to find. Out after the fact there was a voluntary notice put out by lexus on this issue which they have extended warranties for. This has already happened twice to me while driving and both times lexus will not fix it under warranty claiming it does not happen when they take it in. They will not fix the problem unless it occurs while their testing even though the notification indicating the issue is coming up. They have also claimed it is safe to drive although it does not seem safe to have a car randomly stall at any point of time. My research has shown that this is a common problem for consumers with this car. It is also understood that the fix would require a considerable amount of time to fix by lexus ( they would need to keep the car for a month). The cost associated with this is likely why they are hesitant to fix.

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.

I have an is 250 lexus, 2007. I purchased the car on october of 2006. Since my purchase, the car jumped back and forwards when the air conditioner was started and sometimes it shake when I stopped on a red light or a stop signal. I have complained about this issue many times but the dealer said that the computer do not detects the problem. Last month (july 22, 2010), I was driving my car on the highway and it unexpectedly decelerates and began to shake. I was unable to drive faster than certain miles. Also, the vsc light came on. My car has been in the dealer for a month right now and they do not have a final and conclusive diagnosis of what caused the incident and how to fix it. Further, I know other persons who this problem was occurred twice, so I expect it to occur again. Momentarily, they indicated that the problem was caused because of an accumulation of coal in the valves but they are still making tests to the car. The people from toyota have not been available to speak with me although I have requested so, and I have met in many occasions with dealer's representatives (they have indicated that they do not have to speak with me). I understand that the fact that the vehicle unexpectedly decelerates while in the highway is a major safety problem that should be taken care of by toyota. I may have caused an accident because of the unexpected speed problem. This car is not safety and something must be done. Moreover, when toyota is hiding it's responsibility.

I was driving to the gym at 5:30 am on july 3, 2008 in my lexus is 250. I pressed on the accelerator after a light turned green and the car took off, speeding faster and faster. I tried using the brakes and that didn't help. I engaged the emergency brake and that didn't work. My car continued to go faster and faster. I was scared to death and didn't know what else to do. Thankfully there was very little traffic due to the time of day. I pressed the electronic ignition button and that didn't work. I was preparing jump out of the car that was now speeding at about 60mph or so when I thought to put the car in park. That finally stopped the car. I jumped out of the car and a pedestrian lent me his cell phone to call my husband. The car was in the middle of the street "bucking" ( the engine was still revving and the car was in park - still running) for about 10 minutes until my husband arrived. He opened the door, checked the mat - it was not on the accelerator pedal. He turned off the car and we called lexus to have them come tow the car to the dealership. The dealership (lexus of watertown, ma) checked the car and told me there was nothing the matter with it. That I was the problem, that the mat was on the accelerator. This was not true. Both my husband and I saw the mat was not on the accelerator. They completely dismissed the entire event. I almost died driving their car and they blamed me (all the time knowing about the problem).

I purchased a 2007 lexus is250 about a month ago from carmax. I was driving at approx 30mph when a cat entered the roadway. I tried to slam on the brakes but the car accelerated instead and quickly gained speed. I don't know how fast I was going when I was able to step on the brake enough for it to stop. Carmax tells me its not their problem, even though they sold me a car that was already recalled. And lexus says that they don't have the part for it but will put me on a waiting list. So, I either gamble with my life and drive the car anyway, or I'm stuck without a vehicle at all. I'm furious!
