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.

Excessive oil consumption. Vehicle burns 3 1/2 qts of oil or more every 1500 miles. Causing my plugs to foul out and check engine code (0300) multiple cylinder misfire causing car to have sluggish acceleration. I took car in to charles barker Lexus and was charged a diag fee and then told the car is burning oil internally and would be $4100 plus parts for further diag. Lexus offered a customer support program for stated issues for 9 years w/ no mileage limitations of which I was never informed of and was within time frame to qualify. At the time I was unaware of the program and now Lexus is telling me my VIN # does not fall under that program and my vehicle is experiencing all of the identical issues. Also transmission solenoid failed causing hard jolt when slowing down before stopping. Fixed solenoid only to then have to replace cars computer. The transmission repair mechanic informed me of the ongoing problems with Lexus transmissions and computer failure for the 2006 gs 300 as well as a class action law suite that was filed because of the same issues excessive oil consumption. I have since contacted Lexus informing them of my issues and they decline to address my issues telling me that my vehicle VIN # does not fall under any recalls. I have spent over $2000 replacing the transmission solenoid and I had the cars computer rebuilt vs spending the additional money to replace it. Lexus denies the issues stated that is well documented on the forums pages and refuses to refund me for monies spent as well as refuses to address excessive oil consumption issues when they just settled a class action lawsuit for the same issues stated and offered a customer support program to pay for the cost of repairs for a period of 9 yrs with no mileage limitations. I have documentation for my repairs and looking for assistance in what action I need to take for this matter.

Takata recall...my 2006 Lexus GS300 has 131,467 miles & is excessively consuming oil. I was told by Lexus that they want to do a diagnostic tests for $2300 to take the engine apart. This problem started last year and is worse now. The low engine oil light comes on after only approximately 2,000 miles. I had the oil topped off & went back in 1,000 miles & there was hardly any oil on the dipstick. On the Lexus forum, this seems to be a common problem with the 2006 GS300 and Lexus needs to take responsibility for issues happening with their vehicles. If the engine were to fail while driving this could be detrimental. There was supposedly a letter about old consumption sent out, but they never contacted me with a letter or at the dealership.

Took my wife's car to jiffy lube in kent wa 98032 and the for got to put oil in the engine so we contacted the jiffy lube Corp..and they came out did the walk around inspection did and took pictures. That's all. Well my rings in the engine are blown because of no oil. So we took the car back to the jl and the worker said if we had any problems they jiffy lube would take care of any problems...so I do have the denial letter.

Engine consumes excess oil before interval services. Engine consumed approximately 5 quarts of total engine oil at 3,000 miles after latest oil change. Engine oil capacity is 6.3 quarts with filter replacement. No leaks have been observed. No blue smoke to rule out engine oil burn indicators. Engine dip stick shows signs of oil reduction after oil change. Checked oil levels after 1,000 miles and again at 3,000 miles. After 3,000 miles, oil is below the recommended intervals to almost non-existent on dipstick. Excess engine oil consumption without adequate knowledge of mechanics poses extreme threat to consumer safety and assets. Have researched 2006 gs 300 known issues - this is one of them. No repairs and/or fixes have been provided by Lexus usa, or Toyota usa.

Vehicle is burning through oil at accelerated rate. There are no oil leak markings from vehicle after vehicle is parked however, low engine oil light comes on within 1000 miles of oil change. The rate of this has been accelerating in the last year. The dealership (kuni Lexus) has inspected it, notified us of some sort of a recall which had an expiration date related to this issue. How can a recall expire" how come I was never notified"

Low engine oil condition with no evidence of leaks. Excessive oil burning and having to constantly check and add several times between regularly scheduled oil changes. Often observed by checking before warning indication. This could lead to major engine failure including sudden lockup, stall, overheating, thrown rods, etc.there is recent evidence and admission from Lexus that the piston rings were defective upon manufacture.

I took my vehicle into Lexus and they confirmed there was a problem with this exact year and make and model for the cars engine misfiring. Lexus has acknowledged there was a campaign to fix this very issue and have confirmed my car needs the work done but has said they will be of no service to me. This problem has been fixed for other customers in the same situation but I feel as though Lexus is directly ignoring me for a serious problem.
