Most likely the drivers door switch, but also check to see if it unlocks while you have the drivers door open . Open and close the door as you hit the switch, if this has some effect, then it could a short in the wiring at the pivot point. Sent from my SM-G955U using Tapatalk

I've had the same issue a couple of times . A bad battery or alternator will cause the electric assist power steering to lag . A cheap after market alternator can also cause it intermittently. There was actually a recall due to this issue also . Funny enough, I actually had this happen for the first time the next day after brought it in for the recall[emoji848] Sent from my SM-G955U using Tapatalk

I've had that happen ,must be a mixing door that's stuck . I'm sure youve pushed buttons trying to switch the airflow already , but keep doing that and it will probably become unstuck unexpectedly. I've had that and other similar weird things happen with the climate control that one day magically fixes itself. Sent from my SM-G955U using Tapatalk

I've been having an ongoing issue of my 2015 suburban going into Reduced Engine Power mode accompanied by a check engine light and stabilitrack light . This has happened in the past and it was a vacuum leak . However, this time I'm getting code P0191 (fuel rail pressure sensor). I've spent tons of money on the following Fuel rail cleaning Throttle body cleaning Fuel pump Fuel rail pressure sensor Checking wiring to the pressure sensor Plugs Wires Coil ECU After all of this I still have an intermittent issue of the truck going into a reduced engine power. It can happen twice in a day , or sometimes go 3 weeks without an occurrence, but it always happens. I carry a code scanner with me at all times because resetting the codes brings the truck back to life temporarily. Has anyone faced this same issue ? And if so what was finally the fix . Thanks people , any insight is much appreciated. Sent from my SM-G955U using Tapatalk

I've been dealing with the same issue. I get code p0191 along with stabilitrak and reduced engine power pop up. Plugs Wires Fuel rail cleaning Fuel rail sensor Fuel pump Nothing has fixed the issue and I have to keep an obd2 reader handy to clear the codes in order for the car to drive properly . Bad situation. Thinking that the throttle body or position sensor may be the issue , but I'm going broke trying to find a fix at this point . Sent from my SM-G955U using Tapatalk
