At approximately 85K total miles, IS250 automatic began dropping from 5-6K RPM to 2-3K RPM whenever changing road grade to an incline or decline, usually above 50 mph, dropping to 35 mph on the highway. To maintain proper speed, I would have to downshift from D to S and floor the accelerator. Traction control, parking brake, and ABS lights would sometimes coincide with this problem. This continued until I sold the IS250 at 88K miles.

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.

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.

May of 2009 - leased 09 Lexus IS250; having only driven it for about 1 week when entering the onramp of I-35 in Texas, suddenly realized that car was accelerating out of control. The cruise control locked in by itself. RPM was off the charts. I could not exit at "my" exit and continued South on I-35. I tried to brake, but nothing happened. I called my husband and told him my car was out of control. I kept trying to brake...still nothing. Somehow the car started to slow, I got on the shoulder and kept going for 1-2 miles. I tried to put the car into neutral...RPM's again were out of control. I think that then I immediately put the car into "park" and pushed the engine start/stop button and waited for help. Luckily, I or no one else was injured in this incident. Lexus assured me it was because of the floor mats, but I've never been fully convinced. It has only happened that one time, but honestly, that's enough for me. I tried to trade the car in, but salesman said it was not a good idea ($) since the car was new.

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. Updated 05/24/10

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.

This was a loaner car. The gas pedal stuck on the floor. The heavy rubber mat caught the edge of the gas pedal and held it down on the floor. I was able to shift to neutral (don't know how the engine didn't blow up), brake the car to a stop, shift to park and shut engine off. I saw this morning on tv that there have been fatalities reported on Toyota vehicles related to this issue.
