Problems with 2007 Lexus RX 350 ENGINE AND ENGINE COOLING

My 2007 rx350 was in for 50k maintenance service. i was informed of the power steering oil leaking. no dropping of oil was noticed on the parking floor at my home. technician informed that the oil reservoir was almost empty. i was asked to replace the power steering rack. i was told by the lexus technician that about 30% of rx-350 2006 seem to have this issue within 5 years of in service date and toyota/ lexus id not pay any concern for the safety of the owners. i cannot imagine that i am driving on the freeway at highway speeds running without oil in the power steering. please review and advise all owners of this failure and ensure lexus recalls and fix this issue for all owners. *tr

Lexus rx 350s have defective ignition coil packs. they are failing like bad light bulbs. when one fails the vsc and "check engine" lights come on; drive too far and the engine starts to shake so violently you simply can not drive. two of the six in my car have failed so far. i am told toyota used the same engine in their '07 avalons with the same results. they need to recall and replace all of them. *tr

I was driving down the street and my car started making a ticking noise. it got louder and would barely accelerate. it smelled like it was burning and it was smoking. once i got it to the mechanic, he said my oil line burst and i all the oil gushed out. he said he has seen this problem many times before. lexus said they have not heard of this issue, even though when my mechanic called they had over 200 of these parts in stock! *tr

The engine in my 2007 lexus rx-350 began making a loud noise and eventually stopped. fortunately, i was able to maintain control and there was no fire, but the result could have been very different had the event happened on the freeway rather than on a surface street since steering and stopping the vehicle was extremely difficult when the engine died. when i stopped, oil was dripping out onto the ground. after taking the vehicle to westside lexus in houston, it was discovered that a rubber hose on the oil pipe sub assembly (part no. le15707-31030, i believe) had failed, causing the crankcase oil to spray out over the engine and firewall. thankfully, there was no fire--this time! failure of the hose and loss of the crankcase oil caused a number of catastrophic failures to occur. first, since the camshaft or some other valve train component was seizing up, the timing chain jumped time from one of the sprockets, causing at least two of the intake valves to be struck by the pistons, this necessitated replacement of over $2750 worth of parts under warranty, including the alternator which was apparently directly hit with a spray of oil. i asked that the engine be replaced, but westside lexus refused, saying there would be no reduction in engine longevity due to loss of the engine oil. there was no oil showing on the dipstick when it was checked after the incident, but the service technician, mr. tam, reported that there was an estimated 2 quarts remaining in the crankcase when he drained it and that he didn't expect "bottom end" damage to the main bearings, crankshaft, and connecting rods. i don't know whether this is true or not, but i am concerned that something like this could happen with catastrophic results. the service manager, mr. michael lorch, indicated that lexus had experienced similar problems on other vehicles and that the part has been redesigned, but no formal recall has been undertaken. why isn't the hose metal braid instead of rubber? *tr
