My wife parked the cat in garage around 8 pm 5/31/13.she came inside the house and told there is smell of tar. I went and smelled but did not see anything. I thought she must have driven over asphalt. On 6/1/13 I came back from workout and decided to put the car in driveway found pool of fluid on floor below the front passenger side. Moved the car and check what it is, smell like engine oil. I towed the car to pep boys. After examining the car they found oil is leaking underneath of engine and mentioned to me some kind of tube is leaking. Underneath of engine block. They suggested to take to a dealer. I towed the car again to redlands Toyota, redlands, ca 92373. After hearing the problem he said it is similar to a Camry problem which was recalled. He mentioned the V6 engine of Lexus rx 350 and Camry are similar. He checked Lexus recall history, it was not recalled on 6/3/13 he called me and informed that vvti oil line have a pinhole causing oil leak. He also reported as a result of oil leak drive belt is all oily I had to go thru hassel, loss of transportation and mental agony not knowing what happening I did research and found rubber vvti is prone to be leak (2007-2011) and. Lexus re[laced that piece with metal. I contacted Lexus customers service, they will not accept Toyota's finding. I had to take it to Lexus dealer. What a waste of time, gas, and unnecessary hassel.....

I own a 2007 Lexus RX350. When starting my car, a grinding sound is heard coming from the engine every 1 out of 7 or 8 times. The performed a diagnostic test, and the dealer advised that the camshaft tower would need replacing. Apparently this is a common problem with the year, make, and model. The failure mileage was 89,000. Lexus said they woulc cover parts but not labor, labor is 2/3 of the cost (total estimate $3800). Apparently the car is unsafe to drive as is.

While driving on highway engine motor oil suddenly leak (massive leak all over the car underneath and back) and produce burning smoke. Did not know this happen(no warning signals at all) and wind blow the smoke back so the driver can't see it. The motor oil was down to nothing after been told by other driver to stop the car. Tow the car to Lexus dealer and been told the 'rear main seal and front timing cover seal' broke. The deal did not see the problem(rear main seal broke) before and don't know the cause. Did not see any oil leak underneath the car or any warning light for the past 5 years.

I have now had to replace 3 ignition coils. I only have the paperwork for 2 times, but each time the car began to run rough and the engine went off at stops, and the electrical system light went on. The first time this happened, which I think was in 2010, the Lexus technician said it was a fluke. The second time (above date), the Lexus technician said he was beginning to see a lot of ignition coil failures. This last time (today), the technician said replacing faulty ignition coils is now common, and just a part of maintenance. He also said some people were choosing to replace all 6 of them at once so that they wouldn't be stranded at night or on the road, and to save money. Obviously, there's a major problem with Lexus RX350 ignition coils.
