For model year 2006 and 2007 in the USA there is no side indicators to let other drivers know your gonna make a turn. In Japan there was/is fender indicators not sure if they function as signal indicators however were removed or not included in the USA release. I was almost blind sided on the freeway a few days ago cause the driver to my right didn't/couldn't see my signal indicators. Other drivers have to be directly behind or directly in front to see the turn indicators. For model year 2008 to 2011 identical body and style only with the addition of turn signal lights on the rear view mirrors that have a full 180 degree visibility.
When I was driving at night, all of a sudden driver side headlight (low beam) turned off and I was driving with one light all alone. I tried switching on and off but still didn't resolved. Next day morning both lights were glowing but the driver side light went off after 10-15 min. Then I turned off and on, it came back. Not sure whether its a faulty light bulb or something else.

Faulty ECU computer resulting in hard jerk when shifting between first and second gear. The engine repair unit goes bad after 100,000 miles. Multiple vehicles reported the issue after experiencing fuel induction problems and oil loss related to bad .gaskets. Car started jerking on the highway cause a rear end bumper collision while intraffic.
I purchased my vehicle (used) in 2014. I have experienced a rebuilt transmission ($4200), new alternator and now I'm currently experience oil consumption. My car is burning oil at-at-a rapid pace. I have replaced my oil two times in two months. My mechanic has informed me that it's the engine (manufacturer issue) and it is due to carbon build up due to a standard for this make, model and year. It's burning alot of oil that is causing the build up in the engine. It was advised that I should replace the engine (who can afford that) or have it rebuilt. If this a manufacturer defect it is not the responsibility of the owner. This is my only vehicle and I'm a mother of two young children. It's very unsafe for me to drive and is jerking; while I drive. I just topped off my oil again this weekend; due to the oil light coming on. I only have 146,461 miles on the vehicle. …

I have a problem with my 2006 GS300 that I purchased new, I'm the original owner and have my car regularly serviced. Back in 2013 I had my transmission replaced by Lexus of westminster at about 80,000 miles, I was shocked when recently while driving my car starts to pull whenever I start braking whether I'm going slow or fast, I get an extra thump. I took my car to the Lexus of cerritos who stated I need my transmission replaced again. My car only has 169,000 miles on it. So that would make this the 3rd transmission. I feel like I have a lemon car. I have replaced the headlights excessively, I have replaced ECU sensors and even tire pressure sensors as well as starter. I don't believe I should have to replace my transmission so often, I am not a hard driver and the last transmission was replaced less than 60,000 miles ago. …
