3 Air Bag Light On problem of the 2007 Lexus IS

Failure Date: 02/27/2019

We had the passenger airbag replaced as part of a recall. This work was performed by a certified Lexus dealership. When we got the car back after the repair, the passenger airbag light showed �off� even with a passenger in the seat. This airbag light and sensor had always worked correctly prior to the airbag replacement by Lexus. There are multiple complaints of the airbag wiring harness being too short and the replacement airbag causing this same Issue for many other Lexus owners. When we brought the car back to Lexus, they said we would need to purchase a new ecu sensor for thousands of dollars and that this Issue was not part of the recall and not caused by the repair. Again, this Issue arose due to the replacement of the airbag which was performed by Lexus and a required recall.

5 Air Bag Light On problem of the 2006 Lexus IS

Failure Date: 04/07/2017

The srs airbag light randomly comes on at variable times. After running the analysis with a bosch obd1200, it appears that the drivers side knee squib circuit Is showing an open fault. When the seat Is moved back, the wiring harness fails. Its believed that the factory installation of the wiring harness Is too short, causing strain on the harness connector. This causes a fault on the airbag module and renders the drivers side knee airbag inoperable. This should be considered a safety concern and a recall should fix this Issue.

6 Air Bag Light On problem of the 2008 Lexus IS

Failure Date: 09/20/2016

Plug for knee airbag becomes loose and triggers airbag light. Based on dealer feedback this Is a wire harness plug Issue and will cause the knee airbag to not inflate. This Is a potential safety concern cause by a possible design/manufacturing defect.

7 Air Bag Light On problem of the 2008 Lexus IS

Failure Date: 07/08/2016

The srs airbag light went off, needs a new sensor which Is around $1700. The airbags won't work unless the sensor Is replaced which Is a huge safety Issue.

8 Air Bag Light On problem of the 2010 Lexus IS

Failure Date: 02/10/2016

Takata recall. Recently financed a 2010 Lexus Is250 in Dec 2015. Shortly after I can't recall exactly when I noticed the airbag light was lit on, but I never paid much attention because I assumed that it was lit because it meant working active. After doing research I have learned that this was not the case and Is showing defective. This has been and still Is a big concern for many owners for a safety and deadly reasons. I am almost afraid to drive my car now for fear. I also do not not have the possible quoted other complaints for $3,000+ to fix this safety default. I am very disappointed in Lexus/Toyota for not having these defective non safe airbags on recall.

10 Air Bag Light On problem of the 2006 Lexus IS

Failure Date: 10/15/2014

My Lexus Is 250 air bag light came on. I took it in for service and Lexus of las vegas and they informed me that the wiring harness needs to be replaced because Lexus designed the part wrong. I learned that if I'm in an accident that my safety system will not work. Lexus needs to replace my death trap now. Fix the wiring harness. . . . Dulce ward.

11 Air Bag Light On problem of the 2006 Lexus IS

Failure Date: 07/24/2014

The airbag light Is now constantly displaying red on my dashboard. Nalley Lexus of smyrna GA stated that there Is a short in the wire harness and it needs to be repaired at a cost of $3300 or the airbags will not work in the event of a crash. From reading online in the Lexus owners blogs, this Is very common and I have read in the forums that Lexus, in 2006, 2007, installed a wiring harness that was too short. The harness plugs become loose and in some cases the wire insulation becomes chafed and shorts out the airbag system. I am not aware where the poster got their information but I, along with others think this Is should be a saftey recall.

12 Air Bag Light On problem of the 2008 Lexus IS

Failure Date: 06/01/2013

Over time, airbag wiring harness becomes loose and/or disconnected, causing airbag light to illuminate and disabling one or more airbags in the event of a crash. Lexus dealers confirm the problem but will not fix without costly payment.
