Bought a new 2016 XC90 Momentum Plus on 7/23/16. On 7/30/16, the driver's computer went dark and the car lost acceleration. I was in an intersection when the failure occured.
The car was towed back to the dealer.

On 8/2/16, the service department called. They said there was a software bug that required an update.

They don't know exactly where the bug was and told me, "Just like any other repair there is no guarantee that this will not happen again."

That's a fail for Volvo.
