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.
