NHTSA Complaint #11499571 — 2020 FOREST RIVER FLAGSTAFF

The RV came with a heated mattress which I would often used to pre-heat the mattress before going to bed. On 11/23/2022, I turned the mattress heater on level 4 & went out of the camper. After about an hour, the smoke alarm went off & I came into the camper to find a very strong toxic odor. I found the smell was coming from the mattress & immediately turned off the heater. Upon further investigation, I saw a burn hole in the bedding & discovered the mattress smoldering. I feel fortunate that I was not sleeping with the mattress heater on when this occurred & fear the various alternative situations this may have caused. I have notified the RV dealer, as well as the RV, mattress & heating control manufacturers. They have responded but have not notified me as to a resolution or further investigation. The mattress, bedding & the heater control unit are available for inspection. I have made no contact with the fire or police department or my insurance company as I discovered the smoldering mattress before it actually caught fire.
