I bought 2008 Lexus Is250 with 123k miles on 05/18/19. I had inspected by a mechanic prior to purchasing it. On one ocassion pror to accident, I backed out of a drive way. When I shifted the automatic transmission from reverse to drive it sudden accelerated for a brief moment, but it was clear in front of me and I remain in control. It only happened to me that one time that week and I thought nothing of it. In the morning of may 29, 2019 the car was parallel parked with a vehicle both in front behind it. My wife slowly back up the car to allow room to pull out of the parking spot. She turn the front wheels towards the curb so that the front of the car would slightly stick out. When she shifted the automatic transmission from reverse to drive, the car suddenly accelerated, jump over the curb and hit the concrete wall of a school. She panicked at the sudden acceleration and does not remember if she step on any pedal during that time. She only knows it accelerated as soon as she shifted to drive and then the car hit the wall. There were no injuries and no other car was involved. We moved the car off the side walk and notified the insurance and the school admin. The insurance declared it a total loss and took ownership of it. A gasoline car accelerate by opening the throttle to allow more air into the engine. The electronic throttle suddenly open due to the physical electronics and/or software controlling it when the transmission Is shift between reverse and drive. Dr. Ronald a. Belt theory seems plausible. If true you would think just changing the software to get an average of voltage samples would prevent the over compensation of the ecu throttle controller cause by low voltage spikes. . Read more...

3/8/2010 involving 2009 Lexus Is 250: as the driver of the Lexus Is 250 was entering the garage, she was applying pressure to the brake while the garage door was opening. As the driver released the brake to move forward into the garage, the Lexus Is 250 unexpectedly accelerated and the vehicle sped forward. The driver was stopped from going through the garage by forcefully pressing on the brakes and stopped by the garage cabinets. Acceleration marks were present on the asphalt approximately 10 feet before the opening of the garage and brake marks were present inside the garage. This was the first time the unexpected accelerated occurred and we immediately contacted the dealer for direction. The dealer suggested that we bring the car to the dealership for inspection. The owners were not comfortable driving the vehicle to the dealership due to the current incident of defective functioning. The dealer came to pick up the car and the owner followed in a courtesy vehicle back to the dealership. Once at the dealership, the customer service representative notified the owner that they were unable to accept the car do to the damage located in the driver side bumper which was a result of the incident. The dealership had possession of the keys and the vehicle. The owner notified the dealership that he was uncomfortable to drive (or have) a driver take the vehicle home do the vehicle malfunction. The owner was advised to contact 1-800-255-3987. The owner requested to leave the vehicle at the dealership to avoid any other incidents until the malfunction Is investigated. The Lexus Is 250 was taken to the dealership appox 2 weeks ago for maintenance. The driver side mat was removed over 3 months before the incident and no other repairs have been made to the car.

Rapid acceleration, 2009, Is 250, Lexus. Pulling into a parking space with the foot on the brake. Car accelerated, jumped a curb, over a 6 foot wide grass separation and totaled a parked car in front of the parking space. Car was serviced that very day for it's 5,000 mile check. First time we drove the car after being serviced. Had our car repaired for front end damage. Contacted Lexus on their hot line, reported the incident, was instructed to write them with all the details. Have not heard one thing from Lexus corporate since we sent the letter on 12/30/09 no one has checked the car. Contacted the dealer in peoria illinois. They would not return our calls. Confronted them about the problem on Saturday. They would take the car back in a trade. Would require me to take another lease, added a year onto the lease plus increased my monthly payment by $80. This was never an offer to check the vehicle. Car Is basically parked in the garage because we are afraid to drive it. It was not the floor mats. There Is no way that was a problem.

Four incidents of unintended acceleration. On four occasions the 2000 Lexus Is250 I purchased on September 3, 2009 had unintended acceleration of up to 5000 rpm. . Three times this occurred when starting the car in park; the fourth time was when the car was stopped and idling. Twice I had the dealer, thousand oaks, CA Lexus, examine the problem and was told no defect could be found. On the fourth occurrence I noticed my foot was on the edge of the brake pedal and depressing the accelerator simultaneously. I wear only a size 9 shoe, have been a licensed driver for over 65 years and have never had any experiences such as these. I have concluded that either the brake and accelerator pedals are too close to each other or they have been positioned too far to the left, that Is, too close to the steering column causing one's foot to be on the edge of the brake pedal. Since unintended acceleration has been revealed as a problem with the Lexus, I shall appreciated your response to the problem I have described. Thank you.

In early 02/09 I was driving home on interstate 695 n in maryland. I was traveling about 50 mph, when all of a sudden the car suddenly accelerated to about 95 mph through no effort of my own. I did not engage the accelerator pedal to increase the speed of the vehicle. I immediately engaged the foot brake to decelerate and but the car would not slow. Eventually after several attempts I was able to slow the car with the brake but the engine continued to violently rev. As I released the foot brake, the car once again accelerated without engaging the accelerator pedal. Even after engaging the emergency brake, the unaided acceleration and my attempt to decelerate the car continued. I was finally able to slow the car enough to pull out of traffic and over to the emergency lane and eventually stop the motion of the vehicle. Although I was able to bring the car to a stop, the engine continued to rev violently, the back tires spun out of control and the back of the car started to fish tail. I tried a number of different tactics to stop the car completely including, attempting to manually shift gears, putting the car in neutral etc. Finally, after several minutes I was able to turn off the ignition and bring the car to a complete stop and the ordeal came to an end without damaging the car and more importantly without injury to me or others. I had the car towed to dealership that night and explained the situation to the service organization the following day. The service team conducted multiple diagnostic tests but was unable to determine or explain the cause of the unintended acceleration to my satisfaction. One service rep suggested that the floor mat was the cause but I had checked immediately after the ordeal the night before to ensure that the floor mat had not become lodged under the accelerator pedal. Since the dealership was not able to determine the cause of the problem, I decided that the best course of action was to return the car and lease another car.
