LTZDaddy

You know it would seem like they would have this system worked out by now than they do. I mean they've been putting it in other GM vehicles for years! Only wish I had a DIC warning warning. They told me if I had some sort of warning then they would know what to fix. I get the haptic feedback and/or the beep when I'm parking (depending on which one I've got turned on) but I've never got anything as far as the Collision Warning system or the lane keep assist or Lane Drift, flying to the moon, or whatever the heck they want pretend like it is.[emoji37] Sent from my SAMSUNG-SM-G935A using Tapatalk

And it might. ;) Problem is.... This is the Lane Keep Assist that isn't working. As well as the Collision Avoidance warning in the DIC. I get the haptic warnings when parking, THANK GOD. (Need those when positioning in the garage.) ;) Albeit the intensity in the left side of the seat is CONSIDERABLY less than the right. Enough so to where I can't really tell it's on if the right side is already activated. Guess we'll see what this week brings. Sent from my SAMSUNG-SM-G935A using Tapatalk

So I get a couple of PM's from the nice people at GM Customer Support that have been monitoring the forum. That's pretty good news I reckon. Then last Thursday morning I get a message that says they've contacted my local service manager (Dennis) and he's going to be calling me to set up an appointment to bring my brand new LTZ in so that this Enhanced Driver Alert System might FINALLY start working like it's supposed to. The thing is... I never received that call from the service manager Dennis. I go to the dealership Friday afternoon and walk right up in front of him and he never spoke. I asked my service writer what's going on, I tell him that I've been in contact with GM customer support, I have a case number, they have spoken with Dennis, and HE was supposed to call me about fixing my truck. He did not seem too have any clue what I was talking about re calling me and telling me that they were going to fix my truck! That's when he told me that the other truck they had in there they THINK they've got fixed. (That truck was a pearl High Country that was in the shop for over a week.) But that they were waiting to see how that truck worked out before they moved on to try to fix mine. From what I'm being told... What they are trying at this point is a "logic reset". Basically it means that they have to take all the components that are a part of the system and unplug them all. Then reconnect them, one at a time, let them power up, and let the system start to recognize (and I assume initialize) each of the components. Supposedly this is going to fix it. Considering how many components there are.... it sounds like it could be quite labor-intensive. I mean we're talking about bumper sensors, the camera in the windshield, the electric power steering, braking sensor (deceleration), gas pedal sensor (acceleration), yaw sensors (to include front to rear tilt / side to side tilt / steering input angle), whether or not you have your turn signal on, speed sensor, the main computer, the secondary computer(s), and the list goes on. Yet I ***still*** have no idea when they plan on actually FIXING IT. (Much less if they have a clue as to how it works.) [emoji37] Actually I was looking today at some of the information in the DIC that it gets from the yaw sensor. If you tell the DIC to put a page up for off road then it will tell you if you're in 2WD or 4WD/AWD, as well as your front to rear tilt, your side to side tilt, and your steering input angle. It's pretty freaking cool to watch it work as you go down the road... Especially if you're going off road (or just driving through your backyard pulling a 1000 pound trailer full of furniture grade wood scraps for instance).

OMG guys reading this makes my blood pressure go up. I mean first you have the radio that doesn't work which... Okay I get that things happen. But there ought to be a way to fix something when it's broke, right? BTW.... Alpine makes a front end to replace the factory touch screen that includes the entire bezel with the climate control area and the AC vents and all of that. The screen itself is a 10 inch touch screen and it interfaces with all of the OEM electronics and sensors and cameras and a whole bunch of other stuff that you can add to it. It is the most bad mama jama front end that I have ever seen to replace an OEM radio or even an after-market unit for that matter it is just stunning!!!! That being said, it's $4,000!!!!!!! ROTFLMAO (But I want one BAAAAD.) But what really troubles me about the general consensus of the responses on how GM / Chevy regards repairing the problem is what I think everyone should be extremely concerned about not just here but across the board with any make or manufacturer these days. That is the new boilerplate response that "It's not throwing codes so we can't fix it because it's not telling us what to fix". I had my brand new truck with 245 miles on it in the shop last week because the Collision warning and the Lane Keep Assist (or the Lane Warning system for that matter) DOES NOT WORK AT ALL. I know it has to be related to the camera because the camera is what tells it what to do. But it's not kicking codes so as far as the quote unquote "system" is concerned it's working correctly. When mine was in there was a white High Country doing the exact same thing. Or should I say not doing the exact same thing. They had been working on that one for 2 days and couldn't figure it out. So I dropped by there today to pick up my new floor mats and to order some nice sill plates and I asked what the status was. You guessed it. They still don't know what to do with mine. And the High Country... It's still in the shop! They put that guy in a rental / longer. And I guess he's happy.... who knows. It just seems insane to me that they can design a system and know exactly how it works but when it doesn't work they have no clue how to fix it. (Unless of course it's giving them error messages.) Then when it says fix this or fix that they go after it. But without the messages it's like monkeys humping footballs around there. I mean it's not the shops fault because the guys at the shop didn't design the systems.... but you would think at some point that they (GM) would take individuals from these dealerships and train them on these systems to where they could take some sort of initiative and start trying to troubleshoot on their own. That is the problem however... We're in an age where they do not trouble shoot anymore, they do not try to get to the bottom of things anymore, the plug a scanner in and wait for the scanner to tell them what's wrong. And if it doesn't tell them where to look then they just push it to the side and go get something else that does tell them what's going on and where to look and what parts bin to look in. From the post that talks about logic to the one that talks about they should start putting new parts in and making it work all of that makes sense... To us. LOL It's getting a little ridiculous if you ask me. I miss the analog days. ;) I know if mine goes in the shop for a week or two they better put me in something every bit as nice if not nicer than what I'm already driving. Just go ahead and put me in a Stingray 3 LT that'll work. Sent from my SAMSUNG-SM-G935A using Tapatalk

Thanks for reaching out Julianne! PM Sent your way. As of today the service writer told me they still would not do anything because it did not say it was broken. Sent from my SAMSUNG-SM-G935A using Tapatalk

Yes sir... familiar with those puppies. ;) I I owned a flatbed towing business for almost 20 years and have been retired since 03 (at a very early age I might add) due to health reasons. Back in those days (started in 85) you had to buy a Ford if you wanted something with diesel power (which I did for the first 10 years) and in 94 I bought one that was the worst vehicle ever produced by human hands. From that point forward I went with GMC 6500's that were built over spec and underrated at 25995 pounds you could run those trucks 20 hours a day and hardly ever have any trouble out of them.... with absolutely marvelous CAT Power! This thing just astounded me yesterday though because they were telling me "Well we can't fix it because it's not telling us it's broke but we know it's not working". I mean WTF!!! Somebody needs to grow a brain. Sent from my SAMSUNG-SM-G935A using Tapatalk

Hi all, First post... long time GM/GMC owner, (like since the 70's for me, 30's for my dad). Also have been a reader of the forum for years now, (with the 05 Envoy Denali being in the family). ;) Don't mean to hijack here but I have a similar problem. We ordered the Costco Limited Edition Silverado LTZ back on May 27th, and took delivery a week ago (almost). Actually it was a few days late, came in July 8th. Can't say enough good things about the Costco program and just how easy it is, not to mention how much you save. OTOH... I'd NEVER have thought to go that route had I not happened by the Costco truck when building out GMC's and Chevy's online. Honestly I didn't need/want the sunroof or the "limited edition" 22" wheels as building the exact same truck (without those two options) was $2500 less. But after all the numbers were run, (not to mention the Costco $1000 cash card) the net-net wasn't but $500 more for a $2500 price difference... no brainer that one was. ;) We chose Siren Red tint coat, in 4WD, cocoa/dune, which was an upcharge to the base price, albeit only at supplier pricing. Then I added another 2K in 'accessories' after the fact that were not included in the (unchangeable) Costco deal. Without my additions, it was a tick over 59, but ended up well under 51, and still have the $1000 Costco card coming. Win win there. That however is the good news. Being as it's not a daily driver we've not gone out in it much in the last week, just around here locally. Although I had concerns that the LKA and Collision Avoidance wasn't working, but attributed that to small twisty roads here in town, and a lack of any real stop and go traffic to test out the collision avoidance. Yesterday however I made a 65 mile trek well north of Atlanta to my closest Hüper Optik dealer for ceramic 40 in the front doors, ceramic 70 in the back doors, back glass, and sunroof. It's AMAZING how cool it is now compared to before, with the 70 being almost clear, but blocking out all the IR. On that trip I couldn't for the life of me get the Lane Keep Assist to turn on. No green icons, no amber, nothing, zip, nada. It's on of course on the console, and the collision avoidance is set to maximum in the DIC. I had my share of bumper to bumper traffic, brakes being slammed on in front, and never got a warning, EVER. Tried the LKA numerous times and nothing, not even the light in the DIC. The truck has something like 230 miles on it at this point. So today I take it to the dealer and wait, and wait, annnnnnnd wait. Was there 5+ hours while they tried to figure out what was going on. At first the tech was thinking it wasn't LKA, but the warning of lane drift option and haptic seat he was chasing. Then they pulled the build sheet and FINALLY listened to what I was trying to tell them. There was also a brand new High Country in for (what they said) was the same problem. On mine, the tech said there was a power steering fault code (that he cleared) and thought he'd fixed it. (At that time he was still thinking it was only the bumper sensors though that he was trying to fix.) He said the High Country though had no fault codes and nothing with the steering. Go figure..... I confirmed with him though that we're talking about the CAMERA that works with the Lane Keep Assist, not just the sensor warning/haptic seat and/or beeps. At this point he said they couldn't fix it, "Because it's not acting up while it's on, so the system isn't telling us what is wrong". Then went on to say "If it was on, and not working correctly it'd show up in the system". This was AFTER he had taken it for TWO TEST DRIVES!!!!!! I was flabbergasted and said, "So you're telling me that because it ISN'T TELLING YOU what is wrong, that you're not going to fix it, because in your eyes it's working correctly? Even though you've driven it TWICE, and YOU KNOW it's turned on, and YOU KNOW it's not working!" He said, "Yes, that's correct. We can't fix it because we don't know what it's not doing." Although admitted it WAS INDEED ON, just not 'acting' like anything is wrong with it. To which my reply was. "So you're telling me I just bought a $60,000 truck with one of the biggest safety features on it that WASN'T FREE by the way, that doesn't work, doesn't tell you it's not working, and you DON'T KNOW how to fix it? Care to refund my money about now? I mean what the heck? Plus the left side of the seat hardly vibrates, but that's another matter. And the wireless charger doesn't work with my brand new S7 edge. That is a hardware problem, period. (Theirs, not mine, and I don't know if there will EVER be a fix for that.) ;) Ended up leaving the dealership after wasting most of the day there, (like from 8:00 till after 1:00). Service writer was at lunch (tech said he goes for 2 hours), Service Manager was at lunch too, (tech said he's slow when he's there). The tech did say all they could do was get with GM tech support and figure out what to do. It's obvious the system isn't working, and even more (painfully) obvious that they have NO freaking CLUE what to do. Anyhow.... sorry about the hijack/drift. But found this thread, and noticed it was at least similar. If anyone has had (or is) having the same problem I'd love to hear about it. Thanks!
