I have heard of this before and cant remember what the cause ended up being.... Last weekend hurricane matthew decided to turn into a real ******* and turn into a nor'easter and flood my street, my vehicles and my house.... Everythings drying out, yukon has a couple of issues left over, xm not working due to a communication issue message on the screen anytime i try to turn xm on, park assist off in the DIC constantly, and well every time i make a right hand turn or shortly thereafter, it will shut off. I did have an issue with the fuel pump not wanting to work for a day or so, thinking i just got water in the fpcm connector or fuel pump module connector, also noticed i am getting unusually good fuel mileage at the moment though, but i cant see that only affecting rh turns... Any ideas? Been dealing with house last few days, havent had time ti pull codes, plan on pulling them tomorrow....

Sorry about the flood man. Glad to see your still going fine. Now as to the vehicle cutting off during a right turn, that pretty wicked. I can't say that I've ever heard of this. Have you checked for Easter in your tank? Or in any of the Evap lines?

No i cant say i have checked for easter anywhere in my tank or evap lines, lol... water on the other hand, i am trying to run this tank out but am getting such good fuel mileage its taking forever!!! I think i have put about 150-200 miles on less than a 1/4 tank of fuel.... which is unheard of in this thing...normally taking my kids to my exes will use an 1/8-1/4 tank depending on my right foot... have also noticed it randomly feels like its bogging down on me just cruising at steady throttle... almost as if the engine momentarily shuts down and then restarts.... going to check fuel pressure monday when i have access to my fuel pressure guage!!!

A buddy's had a suburban do the same thing it turned out to be a bad fuel pump computer module mounted on the frame rail. Had water intrusion. I'm sure it's prolly the same thing as yours.

Kinda what i was thinking, but hoping not... got screwed with my insurance cancelling my policy and not informing me of it, and past week had been a real eyeopener with this storm to a lot of things....

Forgot about this thread, ended up being the FPCM, being full of water, also lost my prk assist module due to water getting into the connector inside the truck and shorting it out...
