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.

I was driving my 2008 is250 at about 40 MPH on a two lane roadway when I felt the car accelerate suddenly. I took my foot off the gas pedal but it continued to accelerate to 85 MPH. I immediately hit the brake but the vehicle did not stop or even slow down. I had pressed the brake pedal as far as it would go but the vehicle did not respond. The third time I pressed the brake pedal the vehicle began to slow down but would not stop. The speed slowly decreased to about 20 MPH but still did not stop. Luckily there was little traffic volume but I was approaching an intersection. The car was slowing down but not stopping. Finally it came to a crawl just as the traffic light turned green. I let go of the brake and the car thrusted forward. I pressed the brake pedal yet again and the vehicle finally came to a stop. I called lexus dealership to report the problem. They towed the car to their service center. Noone asked for specific details of the incident. It didn't seem that this type of complainant was anything new to them.

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
