2009 Lexus RX350 engine complaints
Page 2 of 2: complaints 11 to 15 of 15, newest first, as owners wrote them.
While driving in the very busy freeway, the car suddenly stopped without any prior warning or any signal. Upon lexus dealer inspection, the cause was , bolts used to secure the variable valve timing control device can become loose, one of the bolts came out and caused the timing chain to break and it broke the engine head, causing the vehicle to stop while being driven. Lexus has not recalled the rx 350 models, however on september 3, 2013 lexus has recalled is 350, is 350c and gs 350 vehicles for the exact same reason. My car has always been serviced at lexus dealer. According to lexus service department, there was no way for me to prevent this or to know. The sudden stop of the vehicle in the freeway as the result of this engine failure could have caused a major accident which was very life threatening. These engines has to be recalled for inspection and repair by lexus. Lexus did not accept the fault even though they accepted to pay partial part of the cost of the rebuilding the engine as a courtesy.
When the SUV shifts from 1st to 2rd gear the engine revs up about 1000 rpms and hesitates 2-5 seconds before the shift takes place. I can't rely on power when needed because of this. It's not constant, about 30% of the time it occurs. The same thing happens when down shifting. The dealer, kendall lexus of eugene oregon (rick strong-service manager) is aware of the problem and says "toyota won't put out a new chip to fix the problem". Rick strong also said" I told the salesman he should inform potential buyers about this problem before they purchase a vehicle". This problem is ongoing since I bought the vehicle.
I was driving my 2009 lexus rx 350 down a major surface street when my power brakes and steering went out. I attempted to drive again after moving to a side street, and my steering and brakes went out 2 more times, I then had my vehicle towed to my lexus dealer. They could not identify the reason for the problem.
Several times a week the engine idles fast on start up and lasts for about five minutes. It does not seem to be related to the weather and there seems to be no identifying factor with which it can be associated.
