Traverse sometimes starts dead ....

I am having a strange problem with my 2019 Traverse and wondered if anyone else has had this happen.

Several times I start it and then ... nothing. The vehicle is running but no entertainment display, no speed display, gas and temp gauges at zero, no RPM, nothing. Yes the engine is running! Could not even get it out of park to move it. Really odd.

If I shut down, then wait a bit then it comes to life fine.

However this has happened several times and I am getting concerned that the next time a restart may not fix it.

New 2019 model Redline. Built late August 2018, got it early September 2018.

Anyone else seen this odd quirk ??

Thanks!
... Mike ...
(It's nice, but I do miss the 99' Silverado it replaced .. not the same at all)

Weird...

Take a video and show it to the dealer. That is what it took for them to believe my "shift to park" issue.

Thanks for the ideas, I saw you video. When it happens I am more concerned about getting it going. Will go in Friday to see if they can fix. Probably won't be able to reproduce it and then they will shrug. I hope not.

Sigh .. should have but did not. Worst decision I ever made. Well maybe the ex-wife was the worst decision ever. It's a toss up.
I could do anything to it and knew it stem to stern. About the only thing you can do with these it get floor mats. Whee!

The black interior of the Redline is nice, but I wish they had added some red piping or color or anything. Had they done some of the things from the impala (ambient light, trim work, etc) it would have been great. Looked at High Country, but that garrish name on the headrest and colors turned me off.

Was used to getting into this before the Traverse. I kinda miss the real wood trim.

This sounds like what happens when you remote start the traverse. If you put your foot on the brake and hit the start button does anything happen?
Thomcat and bsried like this.

I've done this a couple of times. Then remembered to hit start.

Good call. Thought about that.
Nope it was sit down, press brake, push button, then be surprised. Perhaps the computer was having a brain fart or whatever.
Either way if I wait a while, then do the press brake, push button it comes back to normal.
So far.

How hard is the OP pressing on the brake? These VVT engines produce a poor vacuum and require an electric vacuum pump to supply additional vacuum for proper action of the brake booster. Further brake system related monitoring sensors are both electrical controlled by movement of the pedal and hydraulic pressure switch in the line.


Here's my .02 guess.

Some people complain of a hard pedal with the first start..I've had this also...likely because excessive braking in a parking maneuver exhausted the tiny booster reservoir and the electric pump couldn't keep up with demand, or upon sitting there could be bleed out through the check valve. If the pedal is hard, I push hard and have never had all systems fail to start. Once the engine starts engine vacuum and auxiliary pump vacuum charge the booster and pedal assist is obtained.



Could be, and this is just a guess......A light push on the pedal may be enough to trigger the electrical sensor on the pedal, but without hard enough pressure absent any remaining vacuum assist, to trigger the sensor in the hydraulic line with the engine and auxiliary vacuum assist pump off. If so the start obtained using the electrical sensors would mimic a remote start enough to get the engine and HVAC going, but the balance of the ECU functions will only be activated after pushing the pedal again, this time with enough assist to trip the hydraulic pressure sensor, i.e the repeat start should have a softer pedal being fed by engine and auxiliary pump vacuum, even a light foot pressure would then be enough to activate the hydraulic pressure sensor and activate all vehicle functions.


Firm foot pressure on a start is desirable and can't hurt anything other than your foot.

That is an interesting point ... I will mention that to the dealer when I bring it in on Friday.
It does make sense. The only time this has happened if it has sat for a few days, but not every time.
But not all the time. I have been trying to get data to figure out why and be able to recreate it before I bring it in.
I had thought electrical low and computer problem, but your idea make much more sense.
Thanks!
