I recently had to buy a replacement part. I checked online for the part number and prices at Lexus.com--first to make sure I was getting the correct part--and second, to have an idea about what the MSRP was. My local dealer, Rockville Lexus (Rockville, MD) offered to sell me the part for $65 OVER MSRP. You read it correctly--sixty-five dollars over MSRP. I wrote a letter to the company president. I never heard back from him, either. Maybe I'm old-fashioned in expecting a letter--US Postal type--to be responded to within 30 days, but...I don't think so.
I hope not all Lexus dealers are grossly over-charging their retail clients for parts, but apparently ROCKVILLE LEXUS, in ROCKVILLE, MD does. Like Sy Syms used to say "an educated customer is our best customer." Make sure you know the MSRP before putting your money down, and hopefully not overpaying for parts like you would if you bought at the rip-off artists at ROCKVILLE LEXUS.
I bought the part I needed from LEXUS PARTS NOW (https://www.lexuspartsnow.com) for about cost. Significantly below MSRP.
I recently acquired a 1999 Lexus ES300 from a craigslist seller who had removed the TRAC OFF and Check Engine Light bulbs from the instrument panel. I found this out when I went to get my car smog checked and upon investigation, it was pretty obvious that the instrument panel had been tampered with.
When I took everything apart this past weekend I was able to clear three of the five codes that were present but the ones that came back were these knock sensor fails/malfunctions. I believe my problem is that I replaced the OEM sensors with $25 junk from amazon. When it comes to these knock sensors, I've learned that they are incredibly sensitive and if they are not detecting the exact frequencies that the ECU is searching for it will probably throw the CEL.
The problem with these codes is that they will put your vehicle into "limp" mode and disable OD. Since I'm already in too deep to just flip this vehicle out of my life, I've decided to bite the bullet and purchase the OEM sensors for $160+ ea. I'll post an update to the forum when I complete the installation this weekend.
Hopefully this will help someone having similar problems down the line.

I have developed a "clunk" that seems to be coming from the passenger side trunk area when hitting a pothole or pavement change. First thought is a strut or mount going/gone bad so will probably replace all 4 struts. Need suggestions on whether to use OEM parts or aftermarket parts and sources. I prefer a smooth ride versus performance handling. Suggestions on the parts and process appreciated. Should the struts be replaced BEFORE or AFTER a full alignment? The work will be done by a shop, not by yours truly.
