MacBook Pro 2017 A1708 problem with SSD

Sounds like the SSD is most likely bad. The SSD in the non-Touchbar 2016-2017 MBPro has a high rate of failure which usually occur during power on or when waking from sleep as the SSD does not go ready quick enough due to an issue with the SSD's controller. Many times the Kernel Panic will show "nvme" in the beginning of the report where "nvme" is a reference to the type of SSD used in this laptop. The most common Kernel Panic I've seen for these SSD failures is something like "nvme: A fatal error occurred", although there can also be a couple other variations.

I have confirmed the "nvme: A fatal error occurred" is always an SSD failure (assuming there is no liquid damage to the laptop). When I see any other "nvme" based Kernel Panics, I will boot from an external macOS USB3 SSD. I will then sleep the laptop for a little bit, then wake it up to see if it will trigger the SSD to disappear. When that happens, I will check to see if the physical SSD is shown in the Apple System Profiler by clicking "NVMExpress" on the left pane and seeing if the physical SSD information appears on the right pane. If there is no physical information for the SSD, then it confirms an SSD failure since the SSD is the weakest link, but there is always a slim chance of a Logic Board failure affecting the SSD support circuitry.

Fortunately this particular model has a removable internal SSD, so you can replace it with a third party OWC SSD.

Hi,

I suppose your MacBook Pro has power or battery related issue.

You'd better take your MacBook Pro to your local retail AppleStore, Genius Bar or Apple Authorized Service Provider to be examined deep inside of your MacBook Pro there.
