2 questions (bed supports and temp sensor?)

Took off my bed to mount a 16 guage aluminum panel to act as a heat shield for the bed. I’ve had my previous run in with the bed fall apart so I was trying to straighten out the mount. I noticed the other side appears to be following. Anyone else have their bed off a 2015 and check out the back bed mounts?

Bottom support pieces bowing out this is the driver side (no current issue)

Bottom supports bowed heavily tried to straighten now just crooked

Also I believe the harness to the temp sensor is melting, atleast the conduit, known issue new mfg issue?
