When parking the car at a shopping mall, the car suddenly accelerated and jumped the curb. It finally stopped when it hit a stopped bus. Two teenage passengers were in the vehicle. The driver does not believe the accelerator was pressed enough to cause the vehicle to accelerate in the manner it did.

Without warning, the vehicle stopped accelerating as I was driving so I pulled off the road onto the shoulder. Once the car stopped, smoke began to come through the vents so I exited the vehicle. Several minutes later I could see flames coming from under the hood. Before the fire department could make it to the scene, the entire front end of the car burned completely. The fire department said they were going to classify it as a "mechanical failure".

September 20, 2012 I experienced my first misfire issue with my 2008 Lexus is 250. As I accelerated to approx 65 mph to entire a busy highway on ramp, I lost all acceleration in my vehicle. As this happened, I had the check engine light flashing, my check vsc indicator displaying, and my traction control light illuminating. I called Lexus, they advised that the car needed be towed in and the began to run the codes that were tripped. It was determined that I had extreme carbon build up in the engine, which was causing my engine to misfire. They did the "cleaning repair" which involved taking the engine apart, and sending a bunch of parts to a machine shop where they cleaned the heads & pistons. In total, I was without my car for over a month! fast forward to September 3, 2013. I now have 73,000 miles on my car, and the same thing happened again this evening as I was accelerating to approx 40 mph. This time I was on a busy 5 lane road, and lost all acceleration and had to essentially "coast" across 5 lanes of rush hour traffic to get to safety on the shoulder of the road. I immediately called Lexus, and once again they advised me that my car needed to be towed in. Today my service advisor contacted me to inform me that once again I have carbon build up in my engine and that it is misfiring. Unfortunately now, my car is beyond the 70,000 mile drive train warranty. He is working with corporate to see what my next steps are, but I refuse to pay for these repairs, and I do not feel that I should have to since it is essentially a repeat malfunction of an existing issue! it should also be noted that my is has been into the dealership 3x for engine noise/rough start up since I had the repairs completed last year. Every time, I was told that they logged the issue, but were unable to replicate it.

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.

I was driving my vehicle and the vehicle 3 car lengths ahead of me put on his brakes and when I went to put on my brakes my car continued to accelerate and I had no control of the braking and ran into the back of the vehicle. My airbags failed to deploy- my car was a complete loss to the front end ($17,000. 00) and the insurance appraiser,body shop, police officer, towing company were stunned that the airbags failed to deploy do to the severity of impact and damage.

As I was attempting to accelerate, the vsc light and check engine light came on, the car lost power, would not accelerate, and the engine started misfiring.

Car suddenly lurched forward (while my foot was on the brake approaching a stop sign) and struck the vehicle in front of me on January 6, 2012. This problem occurred again in December 2012 and January 2013, I. E. , car lurched forward while driver's foot was on the brake while approaching a stop light/sign. The latter incidents did not result in any accident or injury.

Car parked parallel to curb. Opened door, got into driver's seat, fastened seat belt, turned on ignition, as normal. Shifted from park into drive, immediately engine began to "rev up" uncontrolled, based on sound from engine. After a few seconds of increasing pitch of engine noise, car jumped the curb, over the adjacent side walk, and slammed into the brick wall in front of my house, slid along the wall, and car ended up against the fence of next door neighbor. Car moved about 6 feet in 2-3 seconds. Right hand and wrist of driver was injured on impact, trapezium bone broken in half, and a portion of bone smashed into little pieces. Hand and wrist muscles and tendons strained. Surgery was required two weeks later to put 4 metal rods in wrist to assist healing. In cast for total of 8+ weeks. Many sessions of occupational therapy will be needed to restore wrist and hand function, some loss of function is anticipated, and arthritis in wrist may result. Car damage included front bumper, front grill, front spoiler, grill assembly, headlamp, head lamp assembly, fog lamps, rt front wheel, right front lower arm control, right, left outer tie rod.

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 dealers 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.

My 2009 Is250 accelerated forward while stopped twice in one week. Stopped at red light with brake applied, car accelerated forward and stopped aggressively. Called Lexus of westminster service, 7600 westminster boulevard, westminster, CA 92683, telephone: 714. 890. 6707 and arranged for the car to be dropped off for diagnostics / repaired. Lexus of westminster had my car for one week for evaluation, now Lexus corporate called and said "nothing is wrong with vehicle and pick it up. I requested for Lexus corporate field technician to physically look at car and Lexus declined because there is no physical or property damage.

The contact owns a 2008 Lexus Is250. The contact was driving approximately 2 mph into a parking space. The vehicle surged over a sidewalk and came to a complete stop. The vehicle was taken to an independent mechanic and then transported to an authorized dealer to be repaired. The failure and current mileages were 15,000.

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!.

I was pulling into a parking space. There was a car parked to my left, I was driving slowly to be sure I didn't overlap into a handicap space on my right. Despite my care the car suddenly and independently accelerated forward and struck a building. My car is a 2009 Lexus Is250 and was about 6 months old at the time.

Accelerator recall on Lexus and Toyota. I received a notice undated last year on both of my vehicles 2007 Lexus is-250 and 2007 Toyota camry and we haven't received to the recall letter to have it repaired. This letter states that they don't have a remedy for it yet.

The contact owns a 2008 Lexus is-250 which was purchased in October 2008. He stated while traveling at speeds of less than 25 mph on a two-lane street, the vehicle accelerated uncontrollably. He attempted to depress the brake pedal; however, the vehicle continued to accelerate. He then utilized the emergency brake yet the vehicle continued to accelerate. The contact was able to force the gear shift selector into the park position and shut the vehicle off. When the vehicle came to a complete stop, he noticed that the driver's side floor mats were stuck under the accelerator pedal. The local dealer advised him to remove one of the floor mats from the vehicle. There were no recalls on his specific vehicle to date. The current and failure mileages were under 9,900.

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.

I was driving my wife's Lexus 2008 is 250 out of a parking lot when applying my foot on the brake the car accelerated. I now slammed my foot on the brakes and the car continued to accelerate. The only thing that stopped my car was the car in front of it with very little damage. If the car was not in front of me I was accelerating faster into on coming traffic. My floor mat is not on the floor as after the san diego incident that was Toyota's reasoning. We were told roughly a month and half ago to take the mat out, which I did right away. They can deny it all they want this car was accelerating and getting faster when applying the brake. The policeman at the scene instructed us to not drive this vehicle and to get a loaner which we did. The car was picked up and sent to Lexus in freehold. First we were told nothing is wrong and they test drove it and such. They were keeping it for 3 days now they are telling us they are keeping it for 3 weeks. There are reports all over the web on this with over 2000 complaints. It is obvious there is a major defect in their computer system. They really need to stop covering this up as 16 people have died. Fyi, this has happened to people in Lexus loaners and loaners do not have floor mats. Again, luckily the car was only 15 feet in front of me what if it was 100 ft!.

Hi, with all the news lately regarding the problems with "sticking" gas pedals on certain Toyota models, I wanted to emphasize that I don't believe the problem is limited to toyotas. I had e-mailed you previously to describe similar problems my wife and I have had with our 2006 is 250, where the car felt like it wanted to lurch forward with our foot on the brake pedal. Additionally, the tachometer needle was fluctuating while this was happening. Our car even died once at a stop light for no apparent reason. There is a record of our taking the car into putnam Lexus for inspection of this problem. We never did receive a response from Lexus to our first e-mail. And, we do not feel that a creeping floor mat was the cause of the problems we were experiencing. We feel that the problems we've described need to be investigated further since it is safety related. I just tried four times to send this description to Lexus through their online e-mail system but kept getting, "operation failed, illegal parameters. ".

The contact owns a 2006 Lexus Is250. While the vehicle was traveling 25 mph the contact attempted to brake and noticed that the vehicle had suddenly surged forward . The contact had to turn off the vehicle in order to stop the acceleration. The same failure has occurred on 3 prior occasions. The vehicle has not been diagnosed by the dealership and the failure mileage was 108000,current mileage was 113000.

The contact owns a 2006 Lexus Is250. The contact stated that while driving at various speeds she has experienced unexpected acceleration on seven different occasions. Each time the vehicle was inspected by a dealer and they advised her that would place a device in the vehicle so that if unattended acceleration was to occur the brakes would override it. The vehicle was repaired for the overriding of the acceleration. She has taken it in each time after each failure and they advised her that there was nothing wrong. The failure mileage was unknown.

Lexus fast acceleration in my car. It has happened 4 or 5 times in my 2006 Lexus is 250, which I bought new. At first, I thought it was my fault since I usually wear wide athletic shoes. I thought that I was touching both the brake and accelerator and mentioned it to my sister, who works for a Lexus dealer. She told me that they were coming out with a letter about the floor mats causing the problem. I took the driver's side floor mat out of my car. I checked the clearance and it was about 2 inches. My brother, who was the former chairman of the board of engineers at westinghouse, told me that it sounded like a computer problem. I changed my driving shoes to get some thin sole, narrow puma's. It has happened once since then. I usually only use the Lexus for long trips, and most of the problems happened when I was parking the car after driving a long way. Without thinking what to do, I just put the car into neutral or if I wasn't moving, I'd shift it into park. Turn the engine off. Then, I would restart it and it was ok. I was a bit shaky and my wife thought I was nuts. Around town, I drive my old 1996 Toyota tacoma truck. Never had a problem with it. I bought it new and still use it every day.

"check vsc" engine light come on. Car decelerates while driving on highway. It started to shake when I stopped. Unable to drive faster than 40mph on highway. Lexus unable to fixed it. This is a velocity hazard on the road.

I like to report an incident of a possible manufacture malfunction on my 2008 Lexus Is250. The incident happened on 4/29/2010. I was first stopped for red light in the neutral gear. As I was ready to move forward on green light, I switched the automatic transmission to "drive," however the car just accelerated uncontrollable forward. I immediately stepped the brake pedal repeatedly (~3 times), but the brake didn't work until my car hit the car in front of me. After colliding with the car in front of me, my Lexus engine shut down by itself. I took my car to magnussen's Lexus dealership in fremont, CA, but they could not find a problem. In light of so many problems reported by other drivers against Toyota and Lexus, I started to think my incident is not an isolated case and may be significant for further investigation. I would like to make an official report to the incident that happened to me and ask you to address the possible safety issue. Best regards.

The contact owns a 2006 Lexus Is250. While driving the vehicle rapidly increased its speed up to 90 mph . He attempted to remove the floor- mat from under the accelerator pedal. However, the vehicle veered off of the road and then into a ditch. When the vehicle rolled over, one occupant was ejected from the front seat; since he was not wearing a seat belt. The other three passengers had bruises lacerations, and were hospitalized. The vehicle was completely destroyed. A police report was available. The failure mileage was 24,000.

In light of the recently announced safety recall for this vehicle, we felt compelled to inform you of the following incidents involving the referenced automobile: on or about April 2008 we had just left our house and traveled about two miles when we stopped at a red light. With the vehicle in gear and my foot on the brake, I felt the car attempting to surge forward. I applied greater pressure on the brake pedal and was able to keep the car from moving. This surging did not repeat itself at any other stops that day. ¿ on or about February 27, 2009, my wife had just left costco in our city and traveled about ⽠mile where she stopped at a red light prior to making a left turn. While waiting for the green light, the car suddenly stopped dead; the engine had unexpectedly shut itself off with the car in gear. She attempted to re-start the car several times to no avail. The police was called who in turn called aaa. While waiting for aaa to arrive, she attempted to re-start the vehicle one last time and was surprised to find that it did start successfully. The approximate time between the car's engine dying and being restarted was about 15 minutes. This has never repeated; however, my wife has noticed the engine idling fast while the car was stopped on several occasions. We brought the car into putnam Lexus for inspection on March 6, 2009, where they were unable to duplicate the problem. ¿ on September 2, 2009, we had just exited the freeway when we stopped at the first stop light. The cars engine began idling fast and then began idling rough. With my foot on the brake pedal, I glanced at the tachometer and noticed that the needle was not steady as it normally is but the rpms were fluctuating between a bit higher than normal and a bit lower than normal. This behavior has repeated sporadically on a number of occasions. We do not believe the floor mat caused the above incidents. We have only used the Lexus floor mats that came with the vehicle and the anchor.

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.
