One problem related to air bag light on has been reported for the 2010 Lexus IS250. The most recently reported issues are listed below.
The red airbag light is permanently on on the dashboard that indicates the passenger airbag is off. This is a huge safety issue! although Lexus has realized this is an issue, they are taking advantage of their design flaws and charging an exorbitant price to fix the problem. This should be considered a recall since apparently this issue is widespread amongst all of these models especially after the warranty has expired.
