My 2010 tried to kill me today

[skippy737]

Back ground:
Recently, my vehicle would flash a cel or stabilitrack or airbag light. ( as if possessed by devil. Every once in awhile the radio would go silent ( but not static silent like crossing under a bridge)

Today at highway speed no cruise control set-
I got an airbag light and a chime
Nav turned off radio went silent and screen blank
Both tirn signals would
Flash but not
Make clicking sound
Engine would surge. Id secondarily be able to accelerate, then it would lose power and orher lights would come on and flicker off and repeat
Then, my ac went full hot and unable to control. As i was slowing down and making my way to shoulder.
I figured it was
Electric so inturned off vehicle and restarted it and everyrhing seemed fine except AC nowblows HOT- then when i turn temp to full, nothing will blow out of vents.

Any ideas
Maybe an ECU or something dealing with computers or electronics is my suspect
I fear when i tell the dealer he will simply say cant replicate
Im covered fully under thegmpp so im not worried about cost

Im sure this is a common problem but i havent found any sure fire items to say what it could be

Any ideas

Could be a simple as it needs a new battery or as complicated as a demonic haunting.

Try the battery first before hiring an exorcist.

Battery brand new within 3 months

I just started it after an hr and everything reset

How old is the alternator?

We see allot of these. It's usually a bad ground cable. A loose connection at battery or a bad battery. Every once in a while it's a bad bcm some with water damage.

try replacing the negative battery cable first. A lot of peoples electronics issues have been solved this way

A little dramatic, no? I came in here expecting to hear that the truck went all transformers on you and flipped you down the highway into an oncoming convoy of semis.

Change your battery. My 2007 had the ABS/Stabilitrak warning a couple weeks ago. Chased several different things until the battery died on me. Bought a new battery and the truck now seems to run better in every way.

The initial tech stated its the negative battery cable. There is a tsb on it
Apparently if it exceeds the parameters of 200 millivolts, its gets all gremliny.

I should be notified in a day or two, but apparently its not uncommon

Bad ground cable.

I did a thread on it ages ago.

It's somewhere here.

 

[skippy737]

Yes i read it. They replaced that and the negative battery cable.
So we will see how it works soon.
These writeups allow us to go innand state to the dealership , hey this is the issue, its a known issue, this is what it possibly is and any referring TSBs or recalls, and its under warranty- so there.
So we sound informed and not wiling to accept a "cannot duplicate" answer
