2 Engine And Engine Cooling problem of the 2006 Lexus GS300

Failure Date: 04/05/2018

While bringing the car to a stop, I am experiencing a very hard downshift from 2nd gear to 1st gear. This hard downshift is so abrupt that it feels as if you were rear ended. Research shows this being an electronic failure in the electronic control module backed with hundreds of complaints of this exact issue to this particular year, make and model. In several cases, mentions of a class action lawsuit against Toyota/Lexus have been mentioned. It's a costly, yet unnecessary repair caused by a flawed design within the electronic componentry. . Considering the reoccurrence of this issue on a mass scale, it may be one best addressed via recall.

3 Engine And Engine Cooling problem of the 1998 Lexus GS300

Failure Date: 10/17/2017

Purchased a 98 Gs300 six months ago and my vsc, abs, brake light and check engine warning gauges came up and will not go away. Did some research and found out the brake master cylinder, throttle position sensor and throttle position actuator were the problems. With these few items gone bad my car produces little to no power during acceleration. The car barely gets up to 45 mph with acceleration pedal all the way down to the floor. With the vsc gone bad there is an alarm that stretches to uncomfortable hearing levels that' hurts like the devil. My car will literally stop in the middle of cruising and won't pick up any speed unless I have my foot pedal all the way down to the floor, which also often times causes it to turn off on highways, all types of streets and other areas. Also with these items gone bad my car shifts so hard to the point where it jumps whenever I shift into any position. All in all the vehicle, I feel , is too dangerous to drive at this time.

5 Engine And Engine Cooling problem of the 2006 Lexus GS300

Failure Date: 09/20/2016

When I go to apply the brakes or of I'm coasting slow, the car jerks twice(once while the car is slowing down, and a harder jerk right before the car stops) every Lexus forum I visited where people had 2006 Lexus Gs300 awd's(with the same exact symptoms), they were mis-diagnosed being told it was their transmission, when in actuality it was their ecu that needed to be replaced. That is a computer failure, so I don't understand why there aren't recalls on this.
