2014 GMC Sierra 1500 stabilitrak

[Uefa2k1]

My 2014 Sierra is displaying Service stabilitrak and the ABS light. It has 58k miles and never did this before and only does this when the road is wet and or raining. When this happens the tranny gets confused as to which gear to pick and the truck falls on it's face. Any one have this issue when It's raining? I have seen and searched other posts but couldn't find one where this happens under wet conditions.

So I took my truck into the dealer for a recall and they told me that the code it threw was for the right rear speed sensor. They wanted $240 to replace it so I went ahead and changed it myself. Still the same issue. I also tried the G218 fix by removing the sound material from the ground with no luck. Anyone have any other ideas what could cause my ABS light/ Stabilitrak warning to come on?

Do you happen to have the DTC that set?

Unfortunately no

Assuming you cleared the codes?

Initially After cycling the ignition the light went off. Drove about 15-20 miles and the traction control light flickered then Service Stabilitrak popped up

Not sure if you've solved the problem here.  But I'll add that this situation is happening with me right now.  I did a fresh oil change and a full gas filler-up, decided to add a little fuel additive (Additech).  That evening the family all loaded up to go out. The roads were very wet and there was a slight drizzle.  About a mile onto the HW going 65MPH, my truck starts to feel like it is struggling to maintain speed.  Felt like I had four flat tires pulling an RV uphill.  I pulled over check tires, all were good.  No dash lights were lit up.  Hopped back in and started driving and almost wrecked trying to get up to speed to merge back on the HW.  I took the next exit and barely made it to the gas station.  When I pulled in, all I had to do was take my foot off the accelerator and the truck stopped immediately as if brakes were being applied already.   Just prior to pulling in the station, my DIC was flashing the Stabilitrak dissabled message and the "T/C" light on the instrument panel was lit up. 
 

Left the truck there overnight and had it towed home the next day.  Decided to start it up and put it into gear; Drive, Rev, Drive, Rev...   The lights on the DIC dissapeared so I drove it around the hood for a slow mission and everything seemed normal.  I'm at a loss for what happened other than to think that the fuel additive somehow confused the brain to think the truck was receiving more power than normal and communicated this to the EBCM which was probably compromised because of wet roads.   Sounds like a wild assumption but the more I read up on the Stabilitrak and Traction control in relation to fuel delivery, it makes sense.  Couple this with the code it registered
