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.
