2006 Lexus GS300/430Engine & cooling

Car is consuming excessive amounts of oil. A quart every 200 miles or so. Also even after doing an oil change the car is not leaking the oil but burning it. Please enforce The National Traffic and Motor Vehicle Safety Act (originally enacted in 1966 and now recodified as 49 U.S.C. Chapter 301). Contacted lexus but the car is out of warranty. The car is burning too much oil leading to more pollutants.

Car wouldn't start. Had it diagnosed and found out my fuel pressure sensor had melted and was leaking fuel had it replaced bug still smell gas in and around car. Car was under recalm for same issue years back and was serviced at the dealership. So I don't see how im liable for repairs if it was a problem when the car came off the assembly line

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. That's very low for a 13-year old car. This is my second lexus and it's very troubling to not only read this common problem for this year, and model car. Lexus are usually reliable vehicles.

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.

My lexus 2006 gs300 has misfire problem at 108355 miles, with error codes ps300, 301, and 302. Spoke with dealership (longo lexus), and they told me the customer satisfactory program (csp) is already expired to free repair by lexus in 2016. If lexus has defective valve spring that caused the carbon build up, then they should send us the safety recall letter, and I have never received any. That's very irresponsible in their part.

I have problem with my lexus gs300 129000 miles, engine run roughly at idle and it burns oil like crazy, every 1000 miles I add about 2.5 Q of oil. Looks like its carbon build-up issue on interior valves and components , I'm scared vehicle can stall. Dealer don't want to do anything about that because it's out of warranty already. Please help.

2006 Lexus GS300/430AirbagsEngine & cooling

I took my car into the dealer twice for the oil consumption issues during the period they offered it. I was turned away both times and only after the "repair period" ended was I informed that there was one to begin with. I've read about multiple people having the recall performed who had the same problem as me. My care now needs two to three quarts of oil per month and I was screwed out of my repair. Now we have the airbag light. I've read quite a few things online about temporarily repairing this airbag harness myself but thats not a solution to the actual problem. My children are in this vehicle daily and not having a fully functional airbag system is not at all safe.
