This page covers 6 recalls and 11 owner complaints for the 2010 Lexus Is 350c.
The dominant theme in 2010 Lexus IS 350C complaints centers almost entirely on the airbag system, specifically the driver or passenger airbag inflator. The vast majority of complaints describe owners waiting extended periods, in some cases nearly a year or more, for replacement parts to become available so repairs could be completed. Several owners report signing agreements not to drive their vehicles in the meantime and receiving loaner cars while continuing to make payments on a car they couldn't use. The frustration across these reports isn't about a sudden failure while driving, most owners describe no active airbag malfunction they experienced firsthand, but rather an inability to get the repair done due to parts shortages. One complaint each mentions a tire issue and a powertrain concern, but neither surfaces as a pattern at this complaint volume.

The 2010 Lexus IS 350C has 6 recalls, the most serious being a passenger-side airbag inflator that can rupture and send metal fragments into the cabin, posing a risk of serious injury or death.
This airbag defect affects vehicles registered in high-humidity states and territories, and prior repair attempts did not fully resolve the issue across all affected vehicles, which is why multiple recall campaigns exist for the same problem. On the fuel system side, the fuel pulsation dampers on IS350C models equipped with the 3.5L V6 engine can develop cracks in their internal diaphragms over time, allowing fuel to leak and raising the risk of a fire if that fuel contacts an ignition source. There is also a wiper concern: the wiper motor or linkage can fail, leaving the driver without a working windshield wiper in rain or other low-visibility conditions.
