Good luck, I’m still waiting on the parts my dealer ordered for the repair of the side detection issue..... I will post, once they come in and the parts are installed, at least I’m able to keep and use my truck in the meantime

"This is why I buy foreign. I never have these problems with the Toyota's and Nissans."  Then why did you buy the Chevy in the first place?

What issue are you having with side detection? When I check my codes, I get one for side detection. I clear it and it comes back. No light though.

DIC reads “Service Side Detection System” every time truck is started, and no lane change alerts are working.....dealer said their equipment said my system needed to be reflashed, but when they tried my computer would not accept the the new reflash, they said GM told them to replace sensors and side mirror cameras, been waiting on parts now for over 2 weeks now so far

Does anyone get audible alerts when nearing the edge of a lane?  My lane detection icon on the gauge cluster will go from green to amber and then the electric steering will attempt to move me back into the center of my lane, but I never hear any warning or chime.  Is this behavior normal?

What I found on my Tahoe is the exact same thing you experience. I do get the seat to vibrate if I am about halfway to 3/4 over the line. It doesn’t alert all the time when I go over the line. I have tried intentionally and it wouldn’t do it. I have drifted over the line and it warbled needs. I think it takes into account the force on the steering wheel. Lots of things going on behind the scenes. Also there are setting for audible alert or seat vibrate in the infotainment section under vehicle safety alerts. Hope this helps

For one drive a few months ago I changed the alert settings to have seat vibration.  There is no way to have both the seat vibration and audible alert selected simultaneously in the touch screen menu, you have to pick between one or the other.  I did get the seat vibrating and the red lights illuminating on my windshield somehow when I was moving into a turn lane.  I was confused if this was the lane departure alert or the collision alert because I thought that the red blinking lights on the windshield were for the collision alert functionality.  But have never seen them again.  I went back to audible because it also uses seat vibration for the parking sensors.  I prefer the audible alerts for my parking sensors.

But I have never received an audible alert for going out of my lane, and I have intentionally drifted purposefully many times.  Like I said the icon turns amber from green and the electric steering tries to push me back, but if you go further out of the lane, the icon turns off and the electric steering stops trying to steer me back.  No beeping, never.

Actually it isn't so bad.  My wife had a 2015 and now a 2020 Nissan Rogue and the lane keep warning is very annoying so we turn it off.  Constant beeps unless you're always perfect in your lane and don't move around potholes!  Although if there is something out of the ordinary I would rather it be right rather than wrong.  But if your GM truck is doing the same thing I'd imagine it is normal, hopefully.

It just seems odd that the seat will vibrate if you have it set that way in the menu, but I won't hear any beeps if I have it set to the audible alert.  I would have thought that the seat vibrations were the precise equivalent of the audible alert, so if you received one, you would hear the other.

I’ll change to audible and see if I can get to alert tonight.

You must have LKA  - Lane Keep Assist. (the one that nudges the steering)

 

If it and you are able to stay in the lane -- no warning from LDW (Lane Departure Warning).

 

LDW should give a warning if you cross the line (or at least go beyond where the LKA tries to help) without using blinker. 

 

 

FWIW, vehicles without electric steering (like the HD pickups) can have LDW, but not LKA.  

If it has LKA it will also have LDW, but not necessarily the other way around.

It certainly doesn't give me any warning when crossing the line.  This happens all the time.  Cross the line after the electric steering tries to nudge me back and then nothing happens.  Normally the green or amber lane indicator on the gauge cluster also turns off at the same time since it isn't detecting a lane any longer.

 

However the lane keep assist electric steering is very accurate and does try to nudge me back over appropriately.  And also, the green lane icon does turn amber when it senses I am getting near.  There is no audible warning though what so ever and I've owned the vehicle for two months now.

I've tested it out in depth and it will always appropriately steering the vehicle back over within reason.  But if you force it and cross the line without using the turn signal, nothing happens.

 

By the way, I'm looking at the build sheet that GM sent me.

Anything that pertains to "lane" are only these two items:

UKC - LANE CHANGE ALERT WITH SIDE BLIND ZONE ALERT
UHX - LANE KEEP ASSIST

 

Is it possible that the vehicle is not equipped with lane departure warning?

Thanks.  Interested to hear what you hear, or don't hear.

According to this video regarding the 2015 GMC Sierra, the red lights that illuminated on my windshield awhile back were related to the collision warning system.

However, this video very clearly indicates that an audible tone should be produced when the lane keep assist icon turns from green to amber.  I'm not hearing that audible alert at all, although all of my other audible alerts seem to be working properly, such as the front and rear parking assist warning.  I can't imagine that sound just wouldn't be working if all of the other audio works fine.

 

 

But then you see this video here with a 2018 GMC Yukon Denali, you can see his lane keep icon switching from green to amber and there is definitely no audible alert being produced.  Although he does get an alert to "retake steering" when he takes his hands off of the wheel, which I have never seen either.  Of course the Denali has an entirely different gauge cluster as well.

Can’t speak to an audio alert for lane change system as all I remember is that the little yellow light in my outside side view mirrors used to light up yellow on start up and again if another vehicle was approaching on either side..... now I have no illumination in ether mirror at all, and the DIC warning that my side detection needs service, which just by the way, my service advisor just left me s message that the parts they were waiting on have now arrived, and I need to make an appt to have them installed... probable will get my truck back in next week, hope it all works

      Cam chain tensioner question

      By B14Sierra · Posted

      So I'm in the middle of a DOD AFM delete on my 6.2 L86 Sierra. I had a pick holding the tensioner but after I got the Cam phaser gear off I was cleaning off all the rtv and apparently I didn't have the pick seated far enough in. I bumped it and the tensioner sprang forward.  I think everything is good but I want a second opinion. The top of the tensioner is just a looped piece of plastic that rides in that channel right? There is no spring or anything is there? I got the gear and chain back on and it seems tight and everything looks right. I'm hoping nothing fell out.

      My 2015 1500 LTZ Silverado suddenly won't go into 4 x 4 low. It will go into 4 x 4 high.

      Transmission Woes :-(

      By asilverblazer · Posted

      Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions.

      summer road trips in the 2026 2500HD

      By Chuck FB · Posted

      I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that.
