Causes Related To Notice #PIE0576A:
GM engineering does not currently have a fix for this rare issue. If owners experience either of these no-start issues, the company would like dealerships to ask customers questions about the circumstances of the no-start condition.
Those questions include:
- Was the vehicle parked and for how long?
- Was the vehicle being driven during the no start condition?
- Was it a failure to normally start or a failure to restart after a start/stop event?
- Did the owner hear any abnormal noises during the event?
- Was the vehicle jump started or attempted to be jump started?
- How many times has this condition happened?
- How did the customer or technician eventually get the vehicle started?
- Are there any aftermarket accessories currently plugged into the vehicle?
If Your 2019/2020 Silverado/Sierra Has Had A “No Start” Condition:
Take it to your dealership and mention this notice number. Be prepared to answer questions similar to those mentioned above about the no start condition.
If you have not experienced a no start condition that exactly fits this notice you are not affected and there is nothing you need to do.
