“We had our Lexus smogged and the airbag light was on when we picked it up. We took it to the Lexus dealer and they said it is the wiring harness. $3500 to repair. This is not a component that is supposed to fail, so Lexus should be responsible for the fix.”

“Hi, with all the news lately regarding the problems with sticking gas pedals on certain toyota models, I wanted to emphasize that I don't believe the problem is limited to toyotas. I had e-mailed you previously to describe similar problems my wife and I have had with our 2006 IS 250, where the car felt like it wanted to lurch forward with our foot on the brake pedal. Additionally, the tachometer needle was fluctuating while this was happening. Our car even died once at a stop light for no apparent reason. There is a record of our taking the car into putnam Lexus for inspection of this problem. …”

NHTSA complaint #10669868, filed 2015-01, 65,600 miles

“Vehicle (2006 Lexus is250 w. 62,000 miles) with an illuminated airbag light due to a faulty wiring harness. This is a known problem that Lexus acknowledges but refuse to fix without charging (out of warranty) owners over $3,500. There is even a technical service bulletin ( TSB ) issued for this problem, the TSB number is l-sb-0167-08. This is an outrageous expense and a recall should have been issued. This directly compromises the safety of the drive, passengers and other parties in the even of an accident.”
