NHTSA Complaint #10748834 — 2015 LEXUS RC 350

WHEN I'M USING MY VENTILATED SEATS THE BOTTOM OF THE SEAT IS NICE AND COOL BUT IT FEELS LIKE THE MY BACK IS BEING HEATED. I ALWAYS HAVE VENTILATION ON LOWEST SETTING. THE TOP OF THE SEAT BETWEEN SHOULDER BLADES... VERY HOT!??? SERIOUSLY. I FELT IT WITH MY HAND, AS IF THE VENTILATION WAS SHORTING THE HEATING ELEMENTS. IT STAYED HOT A WHILE AFTER I TURNED OFF VENTILATION. THEN IT COOLED. HAD THIS HAPPEN TO ME ON MY WAY HOME. THE BOTTOM OF THE SEAT WAS COOLING BUT MID BACK THE SEAT GOT VERY HOT. TURNING IT OFF DID CUT THE HEAT AND THEN IT WOULD COME RIGHT BACK WHEN I TURNED IT ON. AND IT SEEMED TO BE GONE. THIS HAPPENED TO ME. TO MAKE SURE I TURNED ON THE VENTILATION ON THE PASSENGER SIDE TOO, NO ONE SITTING IN IT. IT WARMS UP AT THE SAME SPOT AS THE DRIVER SIDE. JUST BELOW SHOULDER BLADE AREA. THE SEAT PORTION IS COOL AND YOU CAN FEEL THE AIR. THE BACK (WARMER PART) IS NOT EMITTING AIR, BUT JUST HOT. TURNED THE SWITCH ON AND OFF, BUT STILL GETS HOT IN THE THE BACK. FINALLY, TURNED THE CAR OFF FOR ABOUT 10 MINUTES. TURNED IT BACK ON, AND THE PROBLEM WENT AWAY. HOWEVER, I FEEL THAT THIS PROBLEM WILL RETURN. JUST USED VENTED SEATS I EXPERIENCED THE EXACT SAME THING. COOLING ON THE SEAT AND IT GOT VERY HOT ABOUT WHERE MY SHOULDER BLADES ARE. IT WAS UNCOMFORTABLE ENOUGH THAT I WAS COOLER LEAVING THEM OFF. I TAKE IT INTO THE DEALER FOR THE 5K CHECKUP SOON. THE BACK OF THE SEAT HEATING IS REALLY ANNOYING!! HOPE IT'S A QUICK FIX! THEY CAN'T REPLICATE THE PROBLEM, THUS UNABLE TO DIAGNOSE. ALTHOUGH I'M NOT HAPPY WITH THE FACT THIS PROBLEM IS NOT RESOLVED, I KNOW THAT THE PROBLEM IS OCCURS AT RANDOM. WE JUST HAVE TO KEEP THEM AWARE THAT THE PROBLEM EXIST BY REPORTING IT. THE SERVICE WRITER CREATED A CASE NUMBER (IT'S PRINTED IN THE PAPERWORK) AND SUBMITTED TO LEXUS CORP. HOPEFULLY WE GET A FIX FOR THIS SOON.
