"Service Driver Assist" 2015 Silverado HD LTZ

This weekend I drove about 300 miles to trade in my 2011 Silverado (LML) for a 2015 Silverado 2500 LTZ Duramax that I thought I had found a great deal on. Against my better judgement, I decided that it was once again ok to purchase a vehicle that was "new and improved" for that year. I had nothing but trouble with my 2011 with transmission issues and DEF/DPF problems CONSTANTLY. Anyway, I got to the dealership in OK and got all the paperwork behind me. As I was driving home I noticed that the Drivers assist would sometimes beep and other times vibrate. I thought that was strange because I had the setting on vibrate, as the beep gets annoying after a bit. Long story short, the intermittent vibrate/beep is getting worse and the vibrate hardly works at all now. The light that says "Service Driver Assist" comes on repeatedly (5 times on my drive home), especially if i get close to the road lines. So, now I feel like I am screwed because the dealer says I need to bring it to them because it is just out of the 36k mile warranty but they are 300 miles from me!!! My last Silverado almost "drove" me into the arms of a Ford or Dodge and I am afraid that this one is definitely off on the wrong foot. That's saying a lot from a guy that has driven only GM and is a 3rd generation GM believer.

 

Does anyone have advice or has anyone seen this problem on their Silverado or Sierra? Any advice is greatly appreciated!

Had a similar issue. Turned out to be an actuator for the driver alert system. When they finished problem solved.

Same problem with my 2015 2500. Stopped at a nearby gmc service shop while driving and Service Driver Assist warning was displayed. Actuator device under seat had a broken wire (vibration apparently breaks the wire). Replaced under warranty, even after 40k miles and all is good now.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.
