Electrical System Problems of Lexus GX470

I have an 2006 Lexus Gx470 and these lights came abs, vsc trac, vsc off, skid, and check engine. The vehicle started making a humming noise at start up and now drives in stalled mode. Had codes check and it turns out I have the dreaded secondary air injection system (emissions) defect p0412, p0418 ,p1440/p1443, p1441/p1444, p2440, p2445, p1442/p1145 , which is a recurring problem. Replacement is a nightmare for self repair or a $2000+ repair.

This is not only a cosmetic issue but a safety issue (passenger side airbag) as well and even Toyota repair manuals say to replace the dash if there are any cracks yet dealers are not addressing the problem and are making owners pay thousands of dollars for a new dash when clearly there's a defect in the materials used to make the dash. This has been an issue for over 5yrs. . Read more...

When I purchased my vehicle from the Lexus dealer it had an occasional thump, bump clunk when I was stopped at stop lights. Sort like someone was trying to bump me forward. I have complained about this at every service appointment including warranty appointments. No one seems to know what it is. It has gotten much worse. I therefore have tried to do some internet research and appears that not only does Lexus know what it is but they might have actually published a technical service bulletin on the problem. I am fearful that the vehicle is becoming unsafe and I believe with the number of complaints I found on the Lexus sites that this is should be a recall issue not an issue that my dealer continually ignores. My Lexus also in cold weather (low 30s) has a large growling noise when stopped and brakes applied. I think it is part of the aforementioned issue. I have had my vehicle aligned a few times. It has a sensation of pulling right. However it stays true, pretty much, on the road. I should not have this feeling in the steering play. Lastly, I am constantly changing out the outside lights on the vehicle. Headlights, turn indicators and rear brake lights.
