    My 2015 GMC Sierra 1500 recently started having all the symptoms under GM internal recall number 18289. I lose my power steering briefly and the electronics turn off momentarily. I lose dash, AC, radio and GPS. It comes back on within a second or two and only does this during low speed turning. I ran my VIN but it does not show under this recall despite having the correct Make/Model/Year. It is currently at the shop because it isn't safe to drive and I was hoping I could get a reimbursement for the repairs. NHTSA Campaign Number: 18V586000 (GM's Internal Number: 18289)

    From time to time since I got the vehicle, the lights flicker inside and out. I've had the alternator changed but it continues. Then when pressing the lock button on the key fob the horn sounds as if it has a shortage. Sometimes its loud and sometimes it's barely heard.

    When backing up, either on a hill or flat surface, the brakes fail to stop the vehicle. There is a pulsing sensation with the brakes due to failure of the vacuum. The brake pedal also becomes impossible to depress. No warning lights appear when this occurs.

    For no apparent reason the truck goes into “low power mode” and gives off code p2138 often happens around 30-35 mph. Have had it happen to me also around 45 mph also. I have replaced sensors and parts to which a month or so goes by and it happens again.
