3 Engine And Engine Cooling problem

Failure Date: 05/01/2016

Hello: I own a 2007 Lexus Is250. My vehicle has had an ongoing engine misfire Issue and has run extremely rough. In addition, my srs light and there Is an Issue with the driver's side knee air bag inflator connector. Finally, my dashboard, front and rear door panels have been sticky and melted over time when it Is hot and there Is no reason why this Is occurring. The dashboard and door panels become glossy, crack and have broken off into pieces and the shine/gloss from the dashboard causes blinding while driving due to the reflection of the sun on the dashboard. These Issues have been going on for a period of over 10 years and I had multiple accidents due to these numerous Issues. I have reported these to Lexus corporate on multiple occasions, including in 2016 and 2017. However, Lexus has refused to fix them stating that they are aware of these Issues and had the zlj, zld and zla warranty programs but that they had expired in 2017. However, I later found out that none of those programs had expired at the time I called Lexus's corporate office. One of their programs, the zld warranty program, was apparently extended until 2021, however, Lexus failed to inform most vehicle owners of this. These Issues are a safety Issue. They have caused my car to malfunction for over 10 years and to have accidents. Many Lexus owners have also reported about these Issues in Lexus owner forums on the internet and have stated that they have had accidents due to these Issues, but Lexus failed to properly inform customers of the extended warranty and refused to fix these cars. With these Issues continuing and becoming worse over the years, they are no longer a warranty Issue, but a safety Issue for drivers. I am requesting that the nhsta investigate this Issue and require, if possible, that Lexus Issue safety recalls for these known defects and fix these Issues immediately to prevent car accidents.

4 Engine And Engine Cooling problem

Failure Date: 04/10/2010

I was driving on a local country road at about 15-20 mph (having just come out of a sharp turn). When I stepped on the accelerator after the turn, it suddenly began to "gun", at which point I stepped on the brake and to my horror got no response. I kept my foot on the brake, but the accelerator continued to rev or gun horrifyingly and the car continued to speed up. At another sharp turn I went off the road and sideswiped a tree, drove through the bedroom of a house (in one wall and out the other) and finally stopped in another tree. After an hour of police, fire, and other emergency personnel attempting to extricate me from the car, they had to remove the roof of the car to get me out of the vehicle. I was airlifted to the nearest hospital with a trauma center, where I was diagnosed with a fractured sternum, three broken ribs, two fractured vertebrae, and a lacerated liver. I was in the hospital for three days, after which I was released with a custom-fitted back brace that I was required to wear for the next six weeks. Fortunately, I was not permanently injured, but I suffer back pain regularly as a result of the fractured vertebrae.
