Cruise Control problems of the 2011 Chevrolet Silverado 1500

1 owner. Never driven on salted roads(south louisiana). Live 100 miles from coastline,not in a saltwater environment. Or driven in water other than rain. Cruise control dropping out, automatic transmission not shifting when supposed to. Traction control dropping out, service messages cycling in and out--traction control, stabilitrac , anti-lock brakes, check engine light, red brake light comes on and off. Speedometer going crazy. Brought vehicle to gm dealer for inspection/repair. Cause- internal failure of ecbm-electronic brake control module, due to corrosion in the connector due to water intrusion. Had to replace the module, and the vehicle chassis wiring harness. Total repair was $1,830. 39 for parts and labor. The dealer reported to me that the design/installation location of this module is flawed, and a faulty design allowed moisture to get into the module thru the connector. Which also resulted in the wiring harness connections into the ecbm also becoming corroded. . Dealer also told me that this faulty design will eventually become a recall, and for me to keep my invoice of this repair, as to be able to claim a reimbursement for this repair.

One night on the way home from work, I was driving 60mph and all of the sudden my truck hydroplaned. I managed to get the truck straight and regain control of the vehicle. About a week later, as I'm heading home all of the sudden my abs, brake, and traction control lights all illuminated. The dic reads service stabilitrak and service traction control, then it will display stabilitrak off and traction control off. I had the codes read and my trouble code was p069e - fuel pump control module requested mil illumination and u0073 - control module communication bus a off. All those lights mentioned above have been on for about a month. I looked up information about the fpcm and found out about gm recall 14515, I entered my VIN but the only recall that came up was for the takata airbag recall. As I read through the 14515 recall, I feel my truck is affected by it because, while driving the truck my speedometer jumps all around and is not stable. Also, when I try to accelerate, it feels like the engine stalls and there's no power there. Other times, it will down shift to increase rpms, but then soon shift gears into a higher gear then shift back into a low gear and repeat this until I let off the pedal. My tow haul mode will not stay engaged, cruise control will not stay engaged, and most of the time my truck won't even start when trying to use the remote start, instead lights just flash as I'm holding down the start button on the key fob. The truck feels really sluggish almost like there's no power, it seems like it hunts for the right gears while driving. Overall it just feels unsafe to drive.

Speed control (cruise) does not hold. While going down an incline from the mountains, cruise control was set for 65 mph, and the vehicle increased speed to 85+ mpg before applying brake to slow down. Called dealership and took vehicle to be checked in regards to this incident, and they stated that due to the department of transportation, new emission standards that transmission was made not to hold so as not to increase carbon footprint. This causes a very unsafe condition when driving when the cruise control is engaged.
