Anybody had this happen - running a few errands, go inside for a bit, come out, start the truck - about 6 warning lights on the dash, messages like "Traction Control off", "Steering assist off", "Brake assist off", "Check Trailer brakes"... and the kicker, "Vehicle speed limited to 43MPH" - which was a good thing since stopping a 4500 pound truck without power assist brakes is a lot of fun Anyhow, drove straight to the dealer, they kept it overnight (was late in the day when I dropped it off) - they called, I picked it up, and all the same warnings were still there! So drove right back into the service bay.... they kept it another 24 hours, made sure it was all clear. Picked it up... about a day later, the "Brake Assist" warning came back on, and the next day, OnStar emailed me with a warning to go get my Anti-lock brakes checked out.... So it's back at the dealer again... I know electronics can be a bit wonky sometimes, but 3 times in a week for basically the same electrical problem... Anybody seen this? (or had this kind of dumb stuff happen from the dealer - wait, nevermind, I know most of you have....)
Excerpts from the Manual below - So it looks like yes, it will come on above 35mph.. only way to keep it off is to be in 4WD-Low From page 27 of my Sierra Manual Traction Control/ Electronic Stability Control The vehicle has a Traction Control System (TCS) that limits wheel spin and the StabiliTrak/Electronic Stability Control (ESC) system that assists with directional control of the vehicle in difficult driving conditions. Both systems come on automatically when the vehicle is started and begins to move. . To turn off TCS, press and release g on the center stack. The traction off light i displays in the instrument cluster. The appropriate Driver Information Center (DIC) message displays. . To turn off both TCS and StabiliTrak/ESC, press and hold g until i and g illuminate GMC Sierra/Sierra Denali Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-1500-11698638) - 2019 - CRC - 3/5/19 28 In Brief in the instrument cluster and the appropriate DIC message displays. . Press and release g again to turn on both systems. StabiliTrak/ESC will automatically turn on if the vehicle exceeds 56 km/h (35 mph). Traction control will remain off. Then from page 247 When the transfer case (if equipped) is in Four-Wheel Drive Low, the stability system is automatically disabled, g comes on, and the appropriate message will appear on the Driver Information Center (DIC). Both traction control and StabiliTrak/ ESC are automatically disabled in this condition.
Yes, but it would take the Software group 6 months to write a Product Requirement Update and get it ratified, and the Q/A testing group another 6 months to make sure the code the programmer put it didn't break anything else. (yes, I work in Software)
I like mine... I like the look of the coating - you can still see the fold seams but they aren't hugely pronounced. It isn't 100% water tight, a bit of water gets inside the bed, but then again, the tailgate isn't 100% sealed either. Only issue I've had was out of the box 1 of the clips to hold the support rods up was broken. I called them and they send a whole bag of them... apparently they break a lot. It's a pretty weak part... The rest of it is great, no issues at all.
I think is a ploy to get you to drive the newer vehicle and plant the seeds of a new purchase... not much help on 2019 to 2020, but if you were driving a 2015 or something, then you drive the 2020 and get excited about a new ride... win for the dealer...
