Lexus RX300 owners have reported 1 problem related to o2 sensor (under the electrical system category). The most recently reported issues are listed below.
I purchased used 1999 Lexus Rx300 in 2008 and so far I've had to replace the transmission due to unexpected catastrophic failure, both air ratio sensors, both knock sensors, oxygen sensor, front strut mounts, and now possibly have to change the transmission again (not shifting correctly). I was not aware that the 1999 to 2001 Rx300s were so problematic. Since this is my only vehicle and I am still making payments on it, I am stuck footing the bill for all these repairs. Which from what I have researched are attributed to bad engineering. I am constantly having to repair a vehicle which is supposedly known for quality. The problems that I've mentioned are just the major repairs. I have other minor issues such as rear power window must remain locked or it opens on it's own, dashboard lights do not illuminate,and power roof gets stuck open intermittently.
