Battery issue?

20silverado20 · March 28, 2023

Recently my battery has died at random times. Sometimes it cranks slow and starts, other times its dead. It started and i drove about 35 minutes to the store, came out less than 10 minutes it was dead. Jumped it and drove home it sat over night and started fine. It does it randomly and nothing is staying on, and i dont have any accessories hooked up to drain in. Could this be the battery? Or the alternator? Its been like this for over a month

Yes, it could be the battery or the alternator.

Take it an AutoZone, or O'Reilly, or any auto parts store and have them check the battery.

Battery is likely since they don't last worth anything anymore.

First time would be the last time.

Have your charging system tested under a load and if the amperage is up to spec. then replace the battery. AC Delco and Die Hard are good brands to consider.

Diagnostic Tip: No Start/ Ignition Will Not Turn ON/ No Power Due To A CAN bus 2 Issue/Lightning Strike/ Failed Over The Air Update

Involved Region or Country

North America

Condition

Some technicians may experience one or more of the following concerns:

No Start
Vehicle will not crank
Vehicle will not enter into Key On, Engine Off mode (Service Mode)
Vehicle's Instrument Panel Cluster will not Illuminate
Vehicle will not shut Off.

In addition to the above concerns, when using GDS2 to connect to the vehicle, the pop up message seen below will be displayed, prompting to turn the ignition on, but the ignition can not be turned on. In some cases, after several ignition button presses, the ignition may turn on. Then, the customer or dealer technician may notice that blower motor turns on at a higher speed and then the ignition will not be able to be turn Off.

Cause

This may be caused by either an issue with Can Bus 2, the vehicle received an "Over The Air" (OTA) update that has failed/ or the vehicle's electrical system was damaged by a voltage spike such as a lightning strike or an incorrect jump start procedure.
