NHTSA defect investigations
Federal safety investigators have looked into a possible defect involving the 2015 Lexus RC 350:
Desiccated Air Bag Inflator Rupture
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited.
What 2015 Lexus RC 350 owners say
Seats
Same issue as stated in NHTSA id numbers 10881898, 10761786 and 10748834. Sporadic seat cooling problem -- panels on seat back sometimes heat in cooling mode. For one test I did, the car was in the garage and cool (so existing heat from the car being parked in the sun was not a factor). I started the car, turned on the seat coolers and got out (so body heat was not a factor). I could very specifically feel heat on the top panel of the seat back (both the driver's seat and the passenger seat). I took it into my local Lexus dealer (September, 2015) and they reported "seats cooling properly without fault". However, as there are 3 other complaints on this issue, there would perhaps seem to be a non-isolated problem.
When I am using my ventilated seats the bottom of the seat is cool and feels good but the back upper portion near shoulder blades feels like its being heated. I have the cold air on in the car and the cold air on in the seats and I can have both at maximum cool and it will still heat up. Worse is that it is random but has been occurring on other cars too as seen in forums. When you turn the cooling seats off it will cool down and when you turn them back on then it will heat up again.
