One problem related to warning light on has been reported for the 2007 Lexus IS250. The most recently reported issues are listed below.
Air bag warning light turned on while we were driving normally. The dealership quoted us the fix will be $3400. Service bulletin for this problem is l-sb-0167-08, and with this, air bag on driver side knee will not deploy. Although this is only a service bulletin, it seems to me as this is a safety issue, therefore, needs to be recalled. The charge of $3400, which basically is 10% of initial cost of the car, is unreasonable, especially given the frequent occurrence reported by other owners of this vehicle and how the problem is at the harness, where consumers have no access to on daily basis. It was reported online that the harness cable is designed to short causing the harness to stretch, which damage the harness over time. My car has not been in a major car accident to cause any alternations and repairs to this part of the vehicle.
