Spyder shifted from reverse to 1st while backing up.

2018 Spyder RT - My wife's Spyder shifted from reverse to 1st while she was backing out of garage. She got it stopped before hitting anything but was wondering if anyone had any ideas concerning this.

Have you tried to replicate the incident on flat, safe ground? Put the Spyder in Reverse, crack the throttle a bit to move the Spyder backward, with your R foot nowhere near the brake pedal, push the shift lever to upshift. If the Spyder shifts to 1st you have a problem with the brake safety interlock.

I have tried to replicate the incident to no avail. I've tried with no brake, partial brake, just touching the brake etc. all while barely moving and at different speeds, again while accelerating and decelerating and cannot get it to happen again.

I am inclined to question the handlebar control as we have had the brake release problem come and go. On our other 2018 we had the handlebar control replaced in the first year we had it due to the brake release issue and failure to shift into and out of reverse. These were intermittent as well. I still have the brake release issue but very infrequently now. Her bike is getting more often with the brake release issue, it happened again yesterday while on a ride following the shifting issue mentioned above. Based on the responses to this post, it doesn't appear to be a common thing.

I am NOT saying this IS the case, but I have seen this happen on several occasions, including myself.
Rider, is looking at the R Button & Shifter, press buttons HEAR the CLUNK, look behind, and hit the THROTTLE.
Bike goes FORWARD!
Why? Because the Bike was NEVER in Reverse.
Hearing the CLUNK is not a guarantee the Bike is in Reverse. You are only in Reverse IF/WHEN that light comes on.
Yeah I know one would think Not Me, but ones realization of a situation does not always align with REALITY.

Yes, I have done exactly that, AJ……only once, mind you

I have been able to replicate the incident. While backing slowly, slight pressure on brake pedal but not applying the brake and bumping the shifter to shift up, the bike will shift and lurch forward.

Since I've no experience with MY '18 RTs I've exhausted my diagnostic ability. You may have a problem with that left handlebar switch assembly. Ouch!
